第1篇 ted英语演讲稿：我们为什么要睡觉

简介：一生中，我们有三分之一的时间都在睡眠中度过。关于睡眠，你又了解多少?睡眠专家russell foster为我们解答为什么要睡觉，以及睡眠对健康的影响。

what i'd like to do today is talk about one of my favorite subjects, and that is the neuroscience of sleep.

now, there is a sound -- (alarm clock) -- aah, it worked -- a sound that is desperately, desperately familiar to most of us, and of course it's the sound of the alarm clock. and what that truly ghastly, awful sound does is stop the single most important behavioral e_perience that we have, and that's sleep. if you're an average sort of person, 36 percent of your life will be spent asleep, which means that if you live to 90, then 32 years will have been spent entirely asleep.

now what that 32 years is telling us is that sleep at some level is important. and yet, for most of us, we don't give sleep a second thought. we throw it away. we really just don't think about sleep. and so what i'd like to do today is change your views, change your ideas and your thoughts about sleep. and the journey that i want to take you on, we need to start by going back in time.

'enjoy the honey-heavy dew of slumber.' any ideas who said that? shakespeare's julius caesar. yes, let me give you a few more quotes. 'o sleep, o gentle sleep, nature's soft nurse, how have i frighted thee?' shakespeare again, from -- i won't say it -- the scottish play. [correction: henry iv, part 2] (laughter) from the same time: 'sleep is the golden chain that ties health and our bodies together.' e_tremely prophetic, by thomas dekker, another elizabethan dramatist.

but if we jump forward 400 years, the tone about sleep changes somewhat. this is from thomas edison, from the beginning of the 20th century. 'sleep is a criminal waste of time and a heritage from our cave days.' bang. (laughter) and if we also jump into the 1980s, some of you may remember that margaret thatcher was reported to have said, 'sleep is for wimps.' and of course the infamous -- what was his name? -- the infamous gordon gekko from 'wall street' said, 'money never sleeps.'

what do we do in the 20th century about sleep? well, of course, we use thomas edison's light bulb to invade the night, and we occupied the dark, and in the process of this occupation, we've treated sleep as an illness, almost. we've treated it as an enemy. at most now, i suppose, we tolerate the need for sleep, and at worst perhaps many of us think of sleep as an illness that needs some sort of a cure. and our ignorance about sleep is really quite profound.

why is it? why do we abandon sleep in our thoughts? well, it's because you don't do anything much while you're asleep, it seems. you don't eat. you don't drink. and you don't have se_. well, most of us anyway. and so therefore it's -- sorry. it's a complete waste of time, right? wrong. actually, sleep is an incredibly important part of our biology, and neuroscientists are beginning to e_plain why it's so very important. so let's move to the brain.

now, here we have a brain. this is donated by a social scientist, and they said they didn't know what it was, or indeed how to use it, so -- (laughter) sorry. so i borrowed it. i don't think they noticed. okay. (laughter)

the point i'm trying to make is that when you're asleep, this thing doesn't shut down. in fact, some areas of the brain are actually more active during the sleep state than during the wake state. the other thing that's really important about sleep is that it doesn't arise from a single structure within the brain, but is to some e_tent a network property, and if we flip the brain on its back -- i love this little bit of spinal cord here -- this bit here is the hypothalamus, and right under there is a whole raft of interesting structures, not least the biological clock. the biological clock tells us when it's good to be up, when it's good to be asleep, and what that structure does is interact with a whole raft of other areas within the hypothalamus, the lateral hypothalamus, the ventrolateral preoptic nuclei. all of those combine, and they send projections down to the brain stem here. the brain stem then projects forward and bathes the corte_, this wonderfully wrinkly bit over here, with neurotransmitters that keep us awake and essentially provide us with our consciousness. so sleep arises from a whole raft of different interactions within the brain, and essentially, sleep is turned on and off as a result of a range of

okay. so where have we got to? we've said that sleep is complicated and it takes 32 years of our life. but what i haven't e_plained is what sleep is about. so why do we sleep? and it won't surprise any of you that, of course, the scientists, we don't have a consensus. there are dozens of different ideas about why we sleep, and i'm going to outline three of those.

the first is sort of the restoration idea, and it's somewhat intuitive. essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night. and indeed, as an e_planation, it goes back to aristotle, so that's, what, 2,300 years ago. it's gone in and out of fashion. it's fashionable at the moment because what's been shown is that within the brain, a whole raft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways. so there's good evidence for the whole restoration hypothesis.

what about energy conservation? again, perhaps intuitive. you essentially sleep to save calories. now, when you do the sums, though, it doesn't really pan out. if you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night. now, that's the equivalent of a hot dog bun. now, i would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep. so i'm less convinced by the energy conservation idea.

but the third idea i'm quite attracted to, which is brain processing and memory consolidation. what we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed. it's really hugely attenuated. so sleep and memory consolidation is also very important. however, it's not just the laying down of memory and recalling it. what's turned out to be really e_citing is that our ability to come up with novel solutions to comple_ problems is hugely enhanced by a night of sleep. in fact, it's been estimated to give us a threefold advantage. sleeping at night enhances our creativity. and what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.

okay. so we've had three e_planations for why we might sleep, and i think the important thing to realize is that the details will vary, and it's probable we sleep for multiple different reasons. but sleep is not an indulgence. it's not some sort of thing that we can take on board rather casually. i think that sleep was once likened to an upgrade from economy to business class, you know, the equiavlent of. it's not even an upgrade from economy to first class. the critical thing to realize is that if you don't sleep, you don't fly. essentially, you never get there, and what's e_traordinary about much of our society these days is that we are desperately sleep-deprived.

so let's now look at sleep deprivation. huge sectors of society are sleep-deprived, and let's look at our sleep-o-meter. so in the 1950s, good data suggests that most of us were getting around about eight hours of sleep a night. nowadays, we sleep one and a half to two hours less every night, so we're in the si_-and-a-half-hours-every-night league. for teenagers, it's worse, much worse. they need nine hours for full brain performance, and many of them, on a school night, are only getting five hours of sleep. it's simply not enough. if we think about other sectors of society, the aged, if you are aged, then your ability to sleep in a single block is somewhat disrupted, and many sleep, again, less than five hours a night. shift work. shift work is e_traordinary, perhaps 20 percent of the working population, and the body clock does not shift to the demands of working at night. it's locked onto the same light-dark cycle as the rest of us. so when the poor old shift worker is going home to try and sleep during the day, desperately tired, the body clock is saying, 'wake up. this is the time to be awake.' so the quality of sleep that you get as a night shift worker is usually very poor, again in that sort of five-hour region. and then, of course, tens of millions of people suffer from jet lag. so who here has jet lag? well, my goodness gracious. well, thank you very much indeed for not falling asleep, because that's what your brain is craving.

one of the things that the brain does is indulge in micro-sleeps, this involuntary falling asleep, and you have essentially no control over it. now, micro-sleeps can be sort of somewhat embarrassing, but they can also be deadly. it's been estimated that 31 percent of drivers will fall asleep at the wheel at least once in their life, and in the u.s., the statistics are pretty good: 100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep. a hundred thousand a year. it's e_traordinary. at another level of terror, we dip into the tragic accidents at chernobyl and indeed the space shuttle challenger, which was so tragically lost. and in the investigations that followed those disasters, poor judgment as a result of e_tended shift work and loss of vigilance and tiredness was attributed to a big chunk of those disasters.

so when you're tired, and you lack sleep, you have poor memory, you have poor creativity, you have increased impulsiveness, and you have overall poor judgment. but my friends, it's so much worse than that.

(laughter)

if you are a tired brain, the brain is craving things to wake it up. so drugs, stimulants. caffeine represents the stimulant of choice across much of the western world. much of the day is fueled by caffeine, and if you're a really naughty tired brain, nicotine. and of course, you're fueling the waking state with these stimulants, and then of course it gets to 11 o'clock at night, and the brain says to itself, 'ah, well actually, i need to be asleep fairly shortly. what do we do about that when i'm feeling completely wired?' well, of course, you then resort to alcohol. now alcohol, short-term, you know, once or twice, to use to mildly sedate you, can be very useful. it can actually ease the sleep transition. but what you must be so aware of is that alcohol doesn't provide sleep, a biological mimic for sleep. it sedates you. so it actually harms some of the neural proccessing that's going on during memory consolidation and memory recall. so it's a short-term acute measure, but for goodness sake, don't become addicted to alcohol as a way of getting to sleep every night.

another connection between loss of sleep is weight gain. if you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. what's the connection here? well, sleep loss seems to give rise to the release of the hormone ghrelin, the hunger hormone. ghrelin is released. it gets to the brain. the brain says, 'i need carbohydrates,' and what it does is seek out carbohydrates and particularly sugars. so there's a link between tiredness and the metabolic predisposition for weight gain.

stress. tired people are massively stressed. and one of the things of stress, of course, is loss of memory, which is what i sort of just then had a little lapse of. but stress is so much more. so if you're acutely stressed, not a great problem, but it's sustained stress associated with sleep loss that's the problem. so sustained stress leads to suppressed immunity, and so tired people tend to have higher rates of overall infection, and there's some very good studies showing that shift workers, for e_ample, have higher rates of cancer. increased levels of stress throw glucose into the circulation. glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. therefore, diabetes 2. stress increases cardiovascular disease as a result of raising blood pressure. so there's a whole raft of things associated with sleep loss that are more than just a mildly impaired brain, which is where i think most people think that sleep loss resides.

so at this point in the talk, this is a nice time to think, well, do you think on the whole i'm getting enough sleep? so a quick show of hands. who feels that they're getting enough sleep here? oh. well, that's pretty impressive. good. we'll talk more about that later, about what are your tips.

so most of us, of course, ask the question, 'well, how do i know whether i'm getting enough sleep?' well, it's not rocket science. if you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived. listen to them. listen to yourself.

what do you do? well -- and this is slightly offensive -- sleep for dummies: make your bedroom a haven for sleep. the first critical thing is make it as dark as you possibly can, and also make it slightly cool. very important. actually, reduce your amount of light e_posure at least half an hour before you go to bed. light increases levels of alertness and will delay sleep. what's the last thing that most of us do before we go to bed? we stand in a massively lit bathroom looking into the mirror cleaning our teeth. it's the worst thing we can possibly do before we went to sleep. turn off those mobile phones. turn off those computers. turn off all of those things that are also going to e_cite the brain. try not to drink caffeine too late in the day, ideally not after lunch. now, we've set about reducing light e_posure before you go to bed, but light e_posure in the morning is very good at setting the biological clock to the light-dark cycle. so seek out morning light. basically, listen to yourself. wind down. do those sorts of things that you know are going to ease you off into the honey-heavy dew of slumber.

okay. that's some facts. what about some myths?

teenagers are lazy. no. poor things. they have a biological predisposition to go to bed late and get up late, so give them a break.

we need eight hours of sleep a night. that's an average. some people need more. some people need less. and what you need to do is listen to your body. do you need that much or do you need more? simple as that.

old people need less sleep. not true. the sleep demands of the aged do not go down. essentially, sleep fragments and becomes less robust, but sleep requirements do not go down.

and the fourth myth is, early to bed, early to rise makes a man healthy, wealthy and wise. well that's wrong at so many different levels. (laughter) there is no, no evidence that getting up early and going to bed early gives you more wealth at all. there's no difference in socioeconomic status. in my e_perience, the only difference between morning people and evening people is that those people that get up in the morning early are just horribly smug.

(laughter) (applause)

okay. so for the last part, the last few minutes, what i want to do is change gears and talk about some really new, breaking areas of neuroscience, which is the association between mental health, mental illness and sleep disruption. we've known for 130 years that in severe mental illness, there is always, always sleep disruption, but it's been largely ignored. in the 1970s, when people started to think about this again, they said, 'yes, well, of course you have sleep disruption in schizophrenia because they're on anti-psychotics. it's the anti-psychotics causing the sleep problems,' ignoring the fact that for a hundred years previously, sleep disruption had been reported before anti-psychotics.

so what's going on? lots of groups, several groups are studying conditions like depression, schizophrenia and bipolar, and what's going on in terms of sleep disruption. we have a big study which we published last year on schizophrenia, and the data were quite e_traordinary. in those individuals with schizophrenia, much of the time, they were awake during the night phase and then they were asleep during the day. other groups showed no 24-hour patterns whatsoever. their sleep was absolutely smashed. and some had no ability to regulate their sleep by the light-dark cycle. they were getting up later and later and later and later each night. it was smashed.

so what's going on? and the really e_citing news is that mental illness and sleep are not simply associated but they are physically linked within the brain. the neural networks that predispose you to normal sleep, give you normal sleep, and those that give you normal mental health are overlapping. and what's the evidence for that? well, genes that have been shown to be very important in the generation of normal sleep, when mutated, when changed, also predispose individuals to mental health problems. and last year, we published a study which showed that a gene that's been linked to schizophrenia, which, when mutated, also smashes the sleep. so we have evidence of a genuine mechanistic overlap between these two important systems.

other work flowed from these studies. the first was that sleep disruption actually precedes certain types of mental illness, and we've shown that in those young individuals who are at high risk of developing bipolar disorder, they already have a sleep abnormality prior to any clinical diagnosis of bipolar. the other bit of data was that sleep disruption may actually e_acerbate, make worse the mental illness state. my colleague dan freeman has used a range of agents which have stabilized sleep and reduced levels of paranoia in those individuals by 50 percent.

so what have we got? we've got, in these connections, some really e_citing things. in terms of the neuroscience, by understanding the neuroscience of these two systems, we're really beginning to understand how both sleep and mental illness are generated and regulated within the brain. the second area is that if we can use sleep and sleep disruption as an early warning signal, then we have the chance of going in. if we know that these individuals are vulnerable, early intervention then becomes possible. and the third, which i think is the most e_citing, is that we can think of the sleep centers within the brain as a new therapeutic target. stabilize sleep in those individuals who are vulnerable, we can certainly make them healthier, but also alleviate some of the appalling symptoms of mental illness.

so let me just finish. what i started by saying is take sleep seriously. our attitudes toward sleep are so very different from a pre-industrial age, when we were almost wrapped in a duvet. we used to understand intuitively the importance of sleep. and this isn't some sort of crystal-waving nonsense. this is a pragmatic response to good health. if you have good sleep, it increases your concentration, attention, decision-making, creativity, social skills, health. if you get sleep, it reduces your mood changes, your stress, your levels of anger, your impulsivity, and your tendency to drink and take drugs. and we finished by saying that an understanding of the neuroscience of sleep is really informing the way we think about some of the causes of mental illness, and indeed is providing us new ways to treat these incredibly debilitating conditions.

jim butcher, the fantasy writer, said, 'sleep is god. go worship.' and i can only recommend that you do the same.

thank you for your attention.

第2篇 我为什么添光彩演讲稿范文

各位评委、在座的各位朋友们：

大家好！我演讲的题目是《我为__添光彩》。

今天站在这里我很高兴，高兴的是能够站在这里表达我的满腔热情；我很自豪，自豪的是我正在为__的发展增光添彩。

我们的__位于中国五大淡水湖之一的__湖畔，是苏北著名的湖滨生态旅游城市，闻名遐迩的“鱼米之乡”，素有“水乡泽国、人间仙境”的美誉。一年前，踌躇满志的我，怀着兴奋和渴望的心情来到了这里。

我是组织部的一名工作人员，也是一名外地来__工作的大学生。刚工作时，我也有过理想与现实落差的忧郁和彷徨，也有过工作和生活失落和苦闷。常常还会有人问，你一个大学生怎么到__来了，怎么不去苏南大城市发展，加上环境的不适应带来的烦躁不安，当初的那份喜悦也渐渐消失。每每此时，我就在思索着自己的人生。直到有一天，我才明白，其实我是缺少精神支柱和理想，工作才没有方向，感到一片茫然。生活，不是缺少精彩，而是需要创造精彩。

著名的黎巴嫩诗人纪伯伦在他的首中曾经这么说过:生活是黑暗的,除非有了渴望；所有渴望都是盲目的,除非有了知识；一切知识都是徒然的,除非有了工作；所有工作都是空虚的,除非有了爱。是啊，当我们带着爱工作时，我们就会与自己与他人、与社会合为一体！掩卷沉思，自己的理想都跑到哪里去了呢？我绝不能这样饱食终日吗？我暗暗下定决心，一定把自己的工作当做生活的乐趣，一定要对自己的工作投入更多的爱，一定要为自己脚踏的这块土地、为自己的第二故乡做点什么！

也许有人会说，一个人的力量那么渺小，又能怎么样呢？的确，一个人的力量往往微不足道，但是如果每个渺小的我们都能付出自己最大的努力，那么我们终能积跬步以至千里，积小流以成江河！我一名普通的组工干部，惟有干好平凡的工作，不懈的努力。努力就意味着要立足岗位，从本职工作做起，从身边小事做起。对待群众时做到“一把椅子让人，一杯开水敬人，一句好话暖人，一张笑脸迎人，一颗诚心感人，一股正气激人”，即便这是平凡的小事，但这却是我对工作的爱，对洪泽的爱，对我脚踏的第二故乡的爱！

人最宝贵的是青春，当回忆往事的时候，不能因为虚度年华而悔恨，也不因碌碌无为而羞耻。不错，与苏南经济发达地区相比，我们__的确属于次发达地区。但是，这不能成为我们停滞不前的理由，相反更应该成为我们迎追赶超、勇往直前的动力。众所周知，我们的__拥有丰富的芒硝、地热资源，元明粉年产量居亚洲第一、世界第二。__盛产鱼、虾、蟹等各种水产品，生态农业独具特色。短短几年，我们的工业经济也突飞猛进，配套设施齐全的工业园区业已成为新的经济增长点。这丰富的资源，这迅猛的发展势头，难道不应该成为我们加快发展的理由吗？这一切的一切不正是由我们__千千万万平凡勤劳的人们一点一滴创造出来的吗？看到这些，我们这些知识青年还有什么理由自怨自艾，有什么理由虚度光阴呢？

如果__是一只展翅待飞的天鹅，我愿做天鹅翅膀上一片小小的羽毛，为天鹅的振翅高飞带来一份力量；如果说__是一条出水的蛟龙，我愿做蛟龙身上的一片鳞光，为腾飞的蛟龙带来灿烂的光芒。

不必走遍中华大地，身居__，就能感受到党的春光。一座座高楼大厦拔地而起。一条条乡村水泥路铺设而成。一户户渔民笑逐颜开。看着这么大好的形势，我们怎能不为之振奋？

未来在我们面前铺就了一张白纸，大笔挥就了__辽阔壮美的远景，剩下的图画将由我们来增光添彩。要想这幅画美轮美奂，每枝画笔都得广集丹青，细细调制，今天、明天以及明天的明天，我愿挥洒我的汗水，用青春和智慧，为__光辉的未来涂抹上最亮丽的色彩！

我的演讲完了，谢谢大家！

第3篇 ted英语演讲稿：为什么_代表未知？

i have the answer to a question that we've all asked. the question is, why is it that the letter _ represents the unknown? now i know we learned that in math class, but now it's everywhere in the culture -- the _ prize, the _-files, project _, ted_. where'd that come from?

about si_ years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is e_tremely precise and carries a lot of information. that's one of the reasons so much of what we've come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.

this includes the little system in arabic called al-jebra. and al-jebr roughly translates to 'the system for reconciling disparate parts.' al-jebr finally came into english as algebra. one e_ample among many.

the arabic te_ts containing this mathematical wisdom finally made their way to europe -- which is to say spain -- in the 11th and 12th centuries. and when they arrived there was tremendous interest in translating this wisdom into a european language.

but there were problems. one problem is there are some sounds in arabic that just don't make it through a european voice bo_ without lots of practice. trust me on that one. also, those very sounds tend not to be represented by the characters that are available in european languages.

here's one of the culprits. this is the letter sheen, and it makes the sound we think of as sh -- 'sh.' it's also the very first letter of the word shalan, which means 'something' just like the the english word 'something' -- some undefined, unknown thing.

now in arabic, we can make this definite by adding the definite article 'al.' so this is al-shalan -- the unknown thing. and this is a word that appears throughout early mathematics, such as this 10th century derivation of proofs.

the problem for the medieval spanish scholars who were tasked with translating this material is that the letter sheen and the word shalan can't be rendered into spanish because spanish doesn't have that sh, that 'sh' sound. so by convention, they created a rule in which they borrowed the ck sound, 'ck' sound, from the classical greek in the form of the letter kai.

later when this material was translated into a common european language, which is to say latin, they simply replaced the greek kai with the latin _. and once that happened, once this material was in latin, it formed the basis for mathematics te_tbooks for almost 600 years.

but now we have the answer to our question. why is it that _ is the unknown? _ is the unknown because you can't say 'sh' in spanish. (laughter) and i thought that was worth sharing.

第4篇 人类为什么要做人造太阳的演讲稿范文

我们人类的自然能源，大约还能用两三百年，即使是核能也是数百年的时间。我觉得能源危机带来一个很大的问题，不光是能源本身，还有雾霾，就是环境的变化，那么未来一定要有更好的清洁能源。科学家做了大量的研究，一种方法是可再生，就像太阳能、风能，但是它们有一个缺点就是不是你想要多少就能来多少，没有太阳就没有太阳能，没有风就没有风能，所以人类未来最终的解决途径就是核聚变，太阳就是一个巨大的聚变体，几十亿年为人类提供了光、热。那么我们怎么才能实现可控的聚变呢？科学家想了很多种方法，希望在地球上实现“人造太阳”这一梦想。如果这个愿望成真，那么我们从海水里提取一杯氘，它就可以产出三百公升汽油这么大的能量。而且聚变非常干净，因为聚变就是把两个氢核放在一起，当温度到了上亿度以后，它们就会聚合在一起，出来的一个是能量，一个是氦，氦是清洁的。在过去的几年中，我们就开始了中国“人造太阳”之梦，大家可以看一看，这个堆叫中国工程聚变热核实验堆，是我本人设计的。这个装置的托卡马克就放在那个主机里面，在红色的主机的中间，周边是发电的功能。这一个装置代表着中华民族腾飞和人类实现聚变的梦想，像一个展翅的大鹏。这就是一个完整的托卡马克“人造太阳”装置，我们做了30年。

为什么我去做这件事？我是1982年大学毕业，在大学里学习很好，高一就上大学，二十岁大学毕业。我有个习惯就是每个礼拜五的下午到图书馆看书，那时候还没有网络。有一天我找到了一个小册子，就讲托卡马克，总共就12页。我当年在上学的时候，王元院士到我们学校去上课，就说看书要从薄到厚，从厚到薄，这是你们大学里都要做的一件事情。这个小册子我看了三遍，从薄到厚，从厚到薄，就是看不懂，不知道什么是托卡马克，我就问老师，老师说这是个好东西，有可能在未来的30年左右发电。我就励志去做这件事情，所以我就考了研究生，考到了我们这个科学岛上。那是一个很漂亮的岛，在一个人造湖的中间。去学了以后我就发现，非常非常复杂，每天都有新东西，越学越觉得很有味道。我觉得这应该是我做的一件事情，觉得自己很幸运。聚变是人类的梦想，国家的需求和我作为科学家的兴趣，这些有机地结合在了一起。所以这件事情，我一直做了34年，现在还在做。

我相信你们在座的各位可能也不知道什么是托卡马克。大家都知道核聚变就是氢弹，实现氢弹也不是非常容易的，它的条件是要实现上亿度。我们有什么办法能够盛装一团上亿度的火球呢？如果我们可以用磁场把这一团火球悬浮起来，那么这时候就有可能继续给它加热，苏联人把这种方法叫做托卡马克。大家看过《钢铁侠》吧，《钢铁侠》里面就有一个这样的装置，中间的这个球不是用有形的东西做的，而是用磁场把它做起来，那些发光的东西就能够把它悬浮起来。温度再高，只要通过悬浮，不碰到材料，那么就不会被烧化。这个时候我们就不断地再给它加热，等达到了上亿度以后它就产生能量。这就是磁约束，这个磁场，这个环境，就叫托卡马克。

从1958年以后，全世界都在做托卡马克。苏联人在70年代末做了一个叫t7的半超导托卡马克，90年代初，他们要做一个更先进的作为第二代，他们希望把第一代装置送到其他国家。我们的前所长是霍裕平院士，他一听到这个消息，立刻就说中国做聚变，不是为了科学家写几个报告，中国做聚变是为了真正解决我们一百年、两百年后的能源问题，所以我们一定要做超导。他很快就跟卡达姆柴夫联系上了，就是俄罗斯的一个科学院的院士。霍老师就提出来用生活用品、羽绒服、牛仔裤、瓷器，大约四百万人民币去跟他换。再加上一起聊天的过程中，喝点伏特加，大家情绪都很高，很快就达成了协议，对方愿意把价值1800万卢布的第一个托卡马克送给我们中国。

因为科学无国界，我们想去做这件事情，就一定要站在巨人的肩膀上。大家可以看到这个装置，在运之前，我们把它所有的部件都拆了下来。为了做这件事情，我们所长用了我们全所上下两年的工资，总共有四百万，我们就勒紧裤腰带。做聚变这件事，一个人是不行的，一定需要一个团队。我们这个合肥超环做成了以后拍了一张照片，你们能找到我在哪儿吗？中间的那个站在猴山上的，唯一穿西服的就是我。我一直说一点，这个团队要相互支持，相护帮助，最重要的一件事情还要相互欣赏，你看到一个人都不喜欢他，都不欣赏他，在一起合作，这是不可能的事情。

经过三年半的时间，我们终于建成了这么一个装置，我们在上面做了很多很多的实验。应该说比苏联科学家做得要好很多。苏联科学家当时只是验证低温工程跟托卡马克是能够用的，所以它只有一秒钟的时间，大约一千万度。我们在这个装置上最高的温度做到了五千万度几秒钟，然后在一千两百万度的情况下，时间达到了最长的四百秒钟，比法国人做得还好。

但是这还远远不够，我刚才说要真的实现聚变的话要到上亿度，需要更长的时间，必须做新一代的全超导托卡马克。2006年的时候，我们第一次建成了一个全超导托卡马克，里面有很多艰辛，有些关键的部件当时是进口俄罗斯的，坏了以后我们自己也不会修，所以要请俄罗斯专家来修。一修的话就有很多困难，我记得有一次，专家来了以后，一下飞机，大约在下午5点半的时候，我们把他接到现场，但是他非常不情愿，他说：“我饿了，”我说：“行，我请你吃饭。”请吃饭后他又说：“我要喝伏特加，”“行”，我说。我也不太擅长喝伏特加，就陪他喝了。喝完伏特加以后，他还说不行，他说：“我已经坐了十几个小时的飞机，很辛苦，我要去睡觉。”然后我们几百人就眼睁睁地看着他吃饱了又去睡觉，我们就在那等。所以从那时起，我们这些人的心里就在想关键技术部分一定要百分之百国产化，最关键的部件我们一定要自己做。

我们做了很多很多研究，比如说用什么方法加热到上亿度，大家都知道加热最方便的方法是微波炉，把饭放进微波炉一分钟就热了。这是全世界最大的微波炉，是我们自己做的，整个加在一起有六个兆瓦，六个兆瓦是什么概念？比平常家里五百瓦到六百瓦的微波炉大一万倍以上。用它连续不断地对这一团火球进行加热，加到上亿度，去年的时候我们就做成了。这个装置我们团队花了将近十五年的心血做到现在，我很自豪地告诉你们，在这个装置的周边，几乎每一个部件都是我们自己做的。

有了这个东西我们就开始一步一步地，从几秒钟到十几秒钟到几百秒钟。我们在上个月做到了一百秒钟五千万度这么一个参数，五千万度什么概念？比太阳心部的温度还要高三倍。我跟你们说这些东西的时候，实际上背后藏着很多的艰辛。我这一辈子，大约做了将近二十万次人造太阳的实验，有将近四万次失败了。失败是什么结果？东西烧坏，打得火星四冒，就像烟花一样。正是因为这一次次的失败才铸造了我们一步一步地往前走，这是一个非常漫长的过程。尽管一百秒离一千秒钟，离一万秒钟的距离还很大，但是我们一直要做。

正是由于聚变这件事情的重要性，所以全世界也都在做，不光是中国人，从1985年开始就在想做这件事。全世界七方联合起来，欧盟二十七个国家算一方，第二方是日本，第三方是俄罗斯，第四方是美国，第五方是中国，第六方是韩国，最后印度也加入了进来，建造的这个托卡马克，我们叫国际热核聚变实验堆。我想说一个小故事，谈判的时候，有很多厂址，就像奥运会一样。日本人希望拉动我们去支持他，把厂址选在日本，为此来了很多很多代表团。第一次来的时候说，如果你支持我们的话，那么我们可以给你百分之十的高层位置，我们说不行，我们依赖于科学，不依赖于位置。第二次又来了，说你们所有到我们这个地方的房租我们全免费，而且给你们的太太免费找工作。大家知道日本妇女一般是没有工作的，但是他们知道中国的女同志是有工作的，我们还是说不行。第三次说，你们只要同意，我们可以给你百分之十的回扣，就是再给你百分之十的东西让你们去做。最后我们一共列出来了十六项技术指标，三项日本是不占优的，第一件事就是地震，厂址那地方有大量的地震；第二有美军基地，旁边美军基地的导弹经常误发在周边；第三没有技术指标，他们也是哑口无言，最后我们一致同意选择在法国。我说这个故事为什么呢？就是科学家做事情，一定要在国家需要你的时候，勇敢地站出来，为国家担当。

讲了那么多，也不知道大家听懂了没有，但是有一点，我觉得聚变是一个值得我们再奋斗很长时间的东西。我已经做了三十四年，很多人说可能还需要五十年，还需要一百年。我觉得这都没有关系，我长期以来有这么一个梦想，就是在我的有生之年，有一盏灯泡能被聚变之能所点亮，这一盏灯泡一定要也只能在中国。

谢谢大家。

第5篇 入党为什么，我为党做了什么演讲稿

入党为什么，为党做什么演讲稿

执法维权党支部 邓润林

大家上午好！感谢大家，让我能在这次“入党为什么，为党做什么”的专题演讲中有表达自己的机会。说实话，站在这里，我非常紧张，不仅因为这是我第一次站在这里，更是因为我要面对众多阅历比我深、见识比我广的领导和同事来谈一个很大的话题。下面我从三个层次来谈谈我个人的粗浅认识，不当之处请各位领导和同事批评指正。

我是在读研究生的时候入党的，在上大学时我们班级只有三四个党员，那时候入党对我来说还是一件遥远的事情。但是一进入研究生班，我们班48个人就有30多个党员，党员成为我们班级的主流群体。那时候，我们班党支部的活动开展的有声有色，党组织成员有许多学习和交流的机会，而我作为一个群众，经常被邀请参加党组织的活动，并给了我很多锻炼和成长的机会，在潜移默化中就很自然的成为了其中名正言顺的一员。我为什么入党，最根本的还是缘于我对______及共产主义思想的认同。

但是，对于共产党及其坚持的共产主义思想，我经历了一个由浅入深的认识过程。思想汇报专题最初，我是从历史资料上了解到，______领导中国人民取得了新民主主义革命和社会主义革命的伟大胜利，并开展了大刀阔斧的社会主义改革，共产党在我心中就是人民的救世主，是我心目中的英雄。后来，我开始思考，历史为什么会从众多的政党中选择共产党？自古以来，成王败寇，青梅煮酒论英雄。成功者自有其成功的理由，必然具有独到和值得称道的地方。共产党能在革命与建设中脱颖而出，不是偶然，而是历史的必然选择。历史为什么会这样选择呢？这还得从共产主义思想说起。

什么样的文化理念就会造就什么样的政党，共产党的先进性就在于他坚持的共产主义思想文化理念具有与生俱来的先进性，在于马列思想揭示的是社会发展的客观规律，而一脉相承的毛泽东思想、邓小平理论、三个代表以及后来的科学发展观是马列思想在中国具体实践中的发展和应用，都是顺应民心，符合广大人民群众的最根本利益，符合自然和社会发展规律的。酷猫写作范文网科学发展观强调和谐，坚持人与自然的和谐发展，坚持经济与社会的和谐发展，这也是共产党在各种客观规律中寻找平衡点的尝试和探索。

在许多地方，毛主席被作为神敬仰和膜拜。中国传统文化认为，神即道，道法自然，毛主席的高明之处也许就在于能认清规律并利用规律做事情。尊重规律，按规律办事，顺势而为，这就是历史的选择。

具体到我们的知识产权事业，随着经济全球化和社会发展，知识产权必将成为企业竞争乃至国家竞争的有力武器，谁拥有了核心知识产权，谁就掌握了行业的制高点，也就在市场竞争中拥有了话语权。随着知识产权成为市场竞争无法回避的话题，海外知识产权摩擦与争端必将加剧，不可否认，我国目前的知识产权状况与发达国家相比还有很大的差距，但是，外有压力，内有需求，知识产权事业必将进入一个高速发展的阶段。这也许还有一个时间的问题，但这是由经济和社会发展规律决定的必然趋势和走向。

我能为党做什么呢？对我而言，最基本的要求就是做好本职工作，从身边的小事做起，从细微处做起。我所在的知识产权维权援助和项目受理窗口是知识产权局接近群众的第一道窗口，也是一个最接地气的服务群众的平台。在人来人往，不知不觉中就会给人知识产权局的最初印象。因此，我必须谨言慎行，规范自己言谈举止，利用专利解答别人的咨询，甚至我还需要耐心倾听别人的抱怨，也可能要分享别人从发明创造中获得的快乐。范文top100我承担的另一项工作是知识产权项目申报，文件制定与具体执行处室如何明确职责分工，如何沟通协作，方便申报单位和个人，切实解决项目申报过程中出现的各类问题，提高工作效率，这都是值得思考，并且下一步应当解决的问题，也是贯彻党的群众路线，为民办实事的要求。而在处理知识产权维权援助案件中，站在为民服务的角度，我们有必要规范案件的受理文件和条件，进一步完善案件的部门移送体系，给维权请求人或投诉人一个满意的答复。这不只是完成工作任务，更是在为民众服务的过程中体现这项工作的价值。在司法鉴定工作方面，可以利用今年的考评评价的机会，完善相关制度，在制度设计时更多的融入为民服务的思想。

我原来在企业工作，也帮朋友打理过一家小企业，我为客户提供过服务，也作为客户享受过别人的服务，其中让我感触很深的是，真正的站在客户的角度想问题，为客户考虑，客户是能感受得到的，最终打动并赢得客户的并非所谓的营销技巧，而是用真心为客户。我想，在这一点上，政府和企业有相通之处，用心为民，民众都是能感受到的，最终也才能发展自己。

有人说，中国是一个缺少信仰的国度，但实际上，共产主义就是一种信仰，而走群众路线，是______按照客观规律做出的

第6篇 奥巴马演讲稿：我们为什么要上学

时间：__年9月8日

地点：弗吉尼亚州，阿林顿市

嗨，大家好！你们今天过得怎么样？我现在和弗吉尼亚州阿林顿郡韦克菲尔德高中的学生们在一起，全国各地也有从幼儿园到高三的众多学生们通过电视关注这里，我很高兴你们能共同分享这一时刻。

我知道，对你们中的许多人来说，今天是开学的第一天，你们中的有一些刚刚进入幼儿园或升上初高中，对你们来说，这是在新学校的第一天，因此，假如你们感到有些紧张，那也是很正常的。我想也会有许多毕业班的学生们正自信满满地准备最后一年的冲刺。不过，我想无论你有多大、在读哪个年级，许多人都打心底里希望现在还在放暑假，以及今天不用那么早起床。我可以理解这份心情。

小时候，我们家在印度尼西亚住过几年，而我妈妈没钱送我去其他美国孩子们上学的地方去读书，因此她决定自己给我上课——时间是每周一到周五的凌晨4点半。显然，我不怎么喜欢那么早就爬起来，很多时候，我就这么在厨房的桌子前睡着了。每当我埋怨的时候，我妈总会用同一副表情看着我说：“小鬼，你以为教你我就很轻松？” 所以，我可以理解你们中的许多人对于开学还需要时间来调整和适应，但今天我站在这里，是为了和你们谈一些重要的事情。我要和你们谈一谈你们每个人的教育，以及在新的学年里，你们应当做些什么。

知名人士11我做过许多关于教育的讲话，也常常用到“责任”这个词。我谈到过教师们有责任激励和启迪你们，督促你们学习。我谈到过家长们有责任看管你们认真学习、完成作业，不要成天只会看电视或打游戏机。

我也很多次谈到过政府有责任设定高标准严要求、协助老师和校长们的工作，改变在有些学校里学生得不到应有的学习机会的现状。但哪怕这一切都达到最好，哪怕我们有最尽职的教师、最好的家长、和最优秀的学校，假如你们不去履行自己的责任的话，那么这一切努力都会白费。——除非你每天准时去上学、除非你认真地听老师讲课、除非你把父母、长辈和其他大人们说的话放在心上、除非你肯付出成功所必需的努力，否则这一切都会失去意义。而这就是我今天讲话的主题：对于自己的教育，你们中每一个人的责任。

首先，我想谈谈你们对于自己有什么责任。 你们中的每一个人都会有自己擅长的东西，每一个人都是有用之材，而发现自己的才能是什么，就是你们要对自己担起的责任。教育给你们提供了发现自己才能的机会。或许你能写出优美的文字——甚至有一天能让那些文字出现在书籍和报刊上——但假如不在英语课上经常练习写作，你不会发现自己有这样的天赋；或许你能成为一个发明家、创造家——甚至设计出像今天的iphone一样流行的产品，或研制出新的药物与疫苗——但假如不在自然科学课程上做上几次实验，你不会知道自己有这样的天赋；或许你能成为一名议员或最高法院法官，但假如你不去加入什么学生会或参加几次辩论赛，你也不会发现自己的才能。而且，我可以向你保证，不管你将来想要做什么，你都需要相应的教育。

知名人士11——你想当名医生、当名教师或当名警官？你想成为护士、成为建筑设计师、律师或军人？无论你选择哪一种职业，良好的教育都必不可少，这世上不存在不把书念完就能拿到好工作的美梦，任何工作，都需要你的汗水、训练与学习。不仅仅对于你们个人的未来有重要意义，你们的教育如何也会对这个国家、乃至世界的未来产生重要影响。今天你们在学校中学习的内容，将会决定我们整个国家在未来迎接重大挑战时的表现。

你们需要在数理科学课程上学习的知识和技能，去治疗癌症、艾滋那样的疾病，和解决我们面临的能源问题与环境问题；你们需要在历史社科课程上培养出的观察力与判断力，来减轻和消除无家可归与贫困、犯罪问题和各种歧视，让这个国家变得更加公平和自由；你们需要在各类课程中逐渐累积和发展出来的创新意识和思维，去创业和建立新的公司与企业，来制造就业机会和推动经济的增长。我们需要你们中的每一个人都培养和发展自己的天赋、技能和才智，来解决我们所面对的最困难的问题。

假如你不这么做——假如你放弃学习——那么你不仅是放弃了自己，也是放弃了你的国家。当然，我明白，读好书并不总是件容易的事。我知道你们中的许多人在生活中面临着各种各样的问题，很难把精力集中在专心读书之上。我知道你们的感受。我父亲在我两岁时就离开了家庭，是母亲一人将我们拉扯大，有时她付不起帐单，有时我们得不到其他孩子们都有的东西，有时我会想，假如父亲在该多好，有时我会感到孤独无助，与周围的环境格格不入。因此我并不总是能专心学习，我做过许多自己觉得丢脸的事情，也惹出过许多不该惹的麻烦，我的生活岌岌可危，随时可能急转直下。但我很幸运。我在许多事上都得到了重来的机会，我得到了去大学读法学院、实现自己梦想的机会。

知名人士11我的妻子——现在得叫她第一夫人米歇尔·奥巴马了——也有着相似的人生故事，她的父母都没读过大学，也没有什么财产，但他们和她都辛勤工作，好让她有机会去这个国家最优秀的学校读书。

你们中有些人可能没有这些有利条件，或许你的生活中没有能为你提供帮助和支持的长辈，或许你的某个家长没有工作、经济拮据，或许你住的社区不那么安全，或许你认识一些会对你产生不良影响的朋友，等等。但归根结底，你的生活状况——你的长相、出身、经济条件、家庭氛围——都不是疏忽学业和态度恶劣的借口，这些不是你去跟老师顶嘴、逃课、或是辍学的借口，这些不是你不好好读书的借口。

你的未来，并不取决于你现在的生活有多好或多坏。没有人为你编排好你的命运，在美国，你的命运由你自己书写，你的未来由你自己掌握。而在这片土地上的每个地方，千千万万和你一样的年轻人正是这样在书写着自己的命运。

例如德克萨斯州罗马市的贾斯敏·佩雷兹。刚进学校时，她根本不会说英语，她住的地方几乎没人上过大学，她的父母也没有受过高等教育，但她努力学习，取得了优异的成绩，靠奖学金进入了布朗大学，如今正在攻读公共卫生专业的博士学位。

我还想起了加利福尼亚州洛斯拉图斯市的安多尼·舒尔兹，他从三岁起就开始与脑癌病魔做斗争，他熬过了一次次治疗与手术——其中一次影响了他的记忆，因此他得花出比常人多几百个小时的时间来完成学业，但他从不曾落下自己的功课。这个秋天，他要开始在大学读书了。

又比如在我的家乡，伊利诺斯州芝加哥市，身为孤儿的香特尔·史蒂夫换过多次收养家庭，从小在治安很差的地区长大，但她努力争取到了在当地保健站工作的机会、发起了一个让青少年远离犯罪团伙的项目，很快，她也将以优异的成绩从中学毕业，去大学深造。贾斯敏、安多尼和香特尔与你们并没有什么不同。

和你们一样，他们也在生活中遭遇各种各样的困难与问题，但他们拒绝放弃，他们选择为自己的教育担起责任、给自己定下奋斗的目标。我希望你们中的每一个人，都能做得到这些。因此，在今天，我号召你们每一个人都为自己的教育定下一个目标——并在之后，尽自己的一切努力去实现它。

知名人士11你的目标可以很简单，像是完成作业、认真听讲或每天阅读——或许你打算参加一些课外活动，或在社区做些志愿工作；或许你决定为那些因为长相或出身等等原因而受嘲弄或欺负的孩子做主、维护他们的权益，因为你和我一样，认为每个孩子都应该能有一个安全的学习环境；或许你认为该学着更好的照顾自己，来为将来的学习做准备……

当然，除此之外，我希望你们都多多洗手、感到身体不舒服的时候要多在家休息，免得大家在秋冬感冒高发季节都得流感。不管你决定做什么，我都希望你能坚持到底，希望你能真的下定决心。我知道有些时候，电视上播放的节目会让你产生这样那样的错觉，似乎你不需要付出多大的努力就能腰缠万贯、功成名就——你会认为只要会唱rap、会打篮球或参加个什么真人秀节目就能坐享其成，但现实是，你几乎没有可能走上其中任何一条道路。因为，成功是件难事。

你不可能对要读的每门课程都兴趣盎然，你不可能和每名带课教师都相处顺利，你也不可能每次都遇上看起来和现实生活有关的作业。而且，并不是每件事，你都能在头一次尝试时获得成功。但那没有关系。因为在这个世界上，最最成功的人们往往也经历过最多的失败。

j.k.罗琳的第一本《哈利·波特》被出版商拒绝了十二次才最终出版；迈克尔·乔丹上高中时被学校的篮球队刷了下来，在他的职业生涯里，他输了几百场比赛、投失过几千次射篮，知道他是怎么说的吗？“我一生不停地失败、失败再失败，这就是我现在成功的原因。”

他们的成功，源于他们明白人不能让失败左右自己——而是要从中吸取经验。从失败中，你可以明白下一次自己可以做出怎样的改变；假如你惹了什么麻烦，那并不说明你就是个捣蛋贵，而是在提醒你，在将来要对自己有更严格的要求；假如你考了个低分，那并不说明你就比别人笨，而是在告诉你，自己得在学习上花更多的时间。没有哪一个人一生出来就擅长做什么事情的，只有努力才能培养出技能。

任何人都不是在第一次接触一项体育运动时就成为校队的代表，任何人都不是在第一次唱一首歌时就找准每一个音，一切都需要熟能生巧。对于学业也是一样，你或许要反复运算才能解出一道数学题的正确答案，你或许需要读一段文字好几遍才能理解它的意思，你或许得把论文改上好几次才能符合提交的标准。这都是很正常的。不要害怕提问。不要不敢向他人求助。——我每天都在这么做。求助并不是软弱的表现，恰恰相反，它说明你有勇气承认自己的不足、并愿意去学习新的知识。所以，有不懂时，就向大人们求助吧——找个你信得过的对象，例如父母、长辈、老师、教练或辅导员——让他们帮助你向目标前进。

知名人士11你要记住，哪怕你表现不好、哪怕你失去信心、哪怕你觉得身边的人都已经放弃了你——永远不要自己放弃自己。因为当你放弃自己的时候，你也放弃了自己的国家。

美国不是一个人们遭遇困难就轻易放弃的国度，在这个国家，人们坚持到底、人们加倍努力，为了他们所热爱的国度，每一个人都尽着自己最大的努力，不会给自己留任何余地。

250年前，有一群和你们一样的学生，他们之后奋起努力、用一场革命最终造就了这个国家；75年前，有一群和你们一样的学生，他们之后战胜了大萧条、赢得了二战；就在20年前，和你们一样的学生们，他们后来创立了google、twitter和facebook,改变了我们人与人之间沟通的方式。因此，今天我想要问你们，你们会做出什么样的贡献？你们将解决什么样的难题？你们能发现什么样的事物？二十、五十或百年之后，假如那时的美国总统也来做一次开学演讲的话，他会怎样描述你们对这个国家所做的一切？你们的家长、你们的老师和我，每一个人都在尽最大的努力，确保你们都能得到应有的教育来回答这些问题。

例如我正在努力为你们提供更安全的教室、更多的书籍、更先进的设施与计算机。但你们也要担起自己的责任。因此我要求你们在今年能够认真起来，我要求你们尽心地去做自己着手的每一件事，我要求你们每一个人都有所成就。请不要让我们失望——不要让你的家人、你的国家和你自己失望。你们要成为我们骄傲，我知道，你们一定可以做到。谢谢大家，上帝保佑你们，上帝保佑美国。

第7篇 ted英语演讲稿：我们为什么快乐？

when you have 21 minutes to speak, two million years seems like a really long time. but evolutionarily, two million years is nothing. and yet in two million years the human brain has nearly tripled in mass, going from the one-and-a-quarter pound brain of our ancestor here, habilis, to the almost three-pound meatloaf that everybody here has between their ears. what is it about a big brain that nature was so eager for every one of us to have one?

well, it turns out when brains triple in size, they don't just get three times bigger; they gain new structures. and one of the main reasons our brain got so big is because it got a new part, called the 'frontal lobe.' and particularly, a part called the 'pre-frontal corte_.' now what does a pre-frontal corte_ do for you that should justify the entire architectural overhaul of the human skull in the blink of evolutionary time?

well, it turns out the pre-frontal corte_ does lots of things, but one of the most important things it does is it is an e_perience simulator. flight pilots practice in flight simulators so that they don't make real mistakes in planes. human beings have this marvelous adaptation that they can actually have e_periences in their heads before they try them out in real life. this is a trick that none of our ancestors could do, and that no other animal can do quite like we can. it's a marvelous adaptation. it's up there with opposable thumbs and standing upright and language as one of the things that got our species out of the trees and into the shopping mall.

now -- (laughter) -- all of you have done this. i mean, you know, ben and jerry's doesn't have liver-and-onion ice cream, and it's not because they whipped some up, tried it and went, 'yuck.' it's because, without leaving your armchair, you can simulate that flavor and say 'yuck' before you make it.

let's see how your e_perience simulators are working. let's just run a quick diagnostic before i proceed with the rest of the talk. here's two different futures that i invite you to contemplate, and you can try to simulate them and tell me which one you think you might prefer. one of them is winning the lottery. this is about 314 million dollars. and the other is becoming paraplegic. so, just give it a moment of thought. you probably don't feel like you need a moment of thought.

interestingly, there are data on these two groups of people, data on how happy they are. and this is e_actly what you e_pected, isn't it? but these aren't the data. i made these up!

these are the data. you failed the pop quiz, and you're hardly five minutes into the lecture. because the fact is that a year after losing the use of their legs, and a year after winning the lotto, lottery winners and paraplegics are equally happy with their lives.

now, don't feel too bad about failing the first pop quiz, because everybody fails all of the pop quizzes all of the time. the research that my laboratory has been doing, that economists and psychologists around the country have been doing, have revealed something really quite startling to us, something we call the 'impact bias,' which is the tendency for the simulator to work badly. for the simulator to make you believe that different outcomes are more different than in fact they really are.

from field studies to laboratory studies, we see that winning or losing an election, gaining or losing a romantic partner, getting or not getting a promotion, passing or not passing a college test, on and on, have far less impact, less intensity and much less duration than people e_pect them to have. in fact, a recent study -- this almost floors me -- a recent study showing how major life traumas affect people suggests that if it happened over three months ago, with only a few e_ceptions, it has no impact whatsoever on your happiness.

why? because happiness can be synthesized. sir thomas brown wrote in 1642, 'i am the happiest man alive. i have that in me that can convert poverty to riches, adversity to prosperity. i am more invulnerable than achilles; fortune hath not one place to hit me.' what kind of remarkable machinery does this guy have in his head?

well, it turns out it's precisely the same remarkable machinery that all off us have. human beings have something that we might think of as a 'psychological immune system.' a system of cognitive processes, largely non-conscious cognitive processes, that help them change their views of the world, so that they can feel better about the worlds in which they find themselves. like sir thomas, you have this machine. unlike sir thomas, you seem not to know it. (laughter)

we synthesize happiness, but we think happiness is a thing to be found. now, you don't need me to give you too many e_amples of people synthesizing happiness, i suspect. though i'm going to show you some e_perimental evidence, you don't have to look very far for evidence.

as a challenge to myself, since i say this once in a while in lectures, i took a copy of the new york times and tried to find some instances of people synthesizing happiness. and here are three guys synthesizing happiness. 'i am so much better off physically, financially, emotionally, mentally and almost every other way.' 'i don't have one minute's regret. it was a glorious e_perience.' 'i believe it turned out for the best.'

who are these characters who are so damn happy? well, the first one is jim wright. some of you are old enough to remember: he was the chairman of the house of representatives and he resigned in disgrace when this young republican named newt gingrich found out about a shady book deal he had done. he lost everything. the most powerful democrat in the country, he lost everything. he lost his money; he lost his power. what does he have to say all these years later about it? 'i am so much better off physically, financially, mentally and in almost every other way.' what other way would there be to be better off? vegetably? minerally? animally? he's pretty much covered them there.

moreese bickham is somebody you've never heard of. moreese bickham uttered these words upon being released. he was 78 years old. he spent 37 years in a louisiana state penitentiary for a crime he didn't commit. he was ultimately e_onerated, at the age of 78, through dna evidence. and what did he have to say about his e_perience? 'i don't have one minute's regret. it was a glorious e_perience.' glorious! this guy is not saying, 'well, you know, there were some nice guys. they had a gym.' it's 'glorious,' a word we usually reserve for something like a religious e_perience.

harry s. langerman uttered these words, and he's somebody you might have known but didn't, because in 1949 he read a little article in the paper about a hamburger stand owned by these two brothers named mcdonalds. and he thought, 'that's a really neat idea!' so he went to find them. they said, 'we can give you a franchise on this for 3,000 bucks.' harry went back to new york, asked his brother who's an investment banker to loan him the 3,000 dollars, and his brother's immortal words were, 'you idiot, nobody eats hamburgers.' he wouldn't lend him the money, and of course si_ months later ray croc had e_actly the same idea. it turns out people do eat hamburgers, and ray croc, for a while, became the richest man in america.

and then finally -- you know, the best of all possible worlds -- some of you recognize this young photo of pete best, who was the original drummer for the beatles, until they, you know, sent him out on an errand and snuck away and picked up ringo on a tour. well, in 1994, when pete best was interviewed -- yes, he's still a drummer; yes, he's a studio musician -- he had this to say: 'i'm happier than i would have been with the beatles.'

okay. there's something important to be learned from these people, and it is the secret of happiness. here it is, finally to be revealed. first: accrue wealth, power, and prestige, then lose it. (laughter) second: spend as much of your life in prison as you possibly can. (laughter) third: make somebody else really, really rich. (laughter) and finally: never ever join the beatles. (laughter)

ok. now i, like ze frank, can predict your ne_t thought, which is, 'yeah, right.' because when people synthesize happiness, as these gentlemen seem to have done, we all smile at them, but we kind of roll our eyes and say, 'yeah right, you never really wanted the job.' 'oh yeah, right. you really didn't have that much in common with her, and you figured that out just about the time she threw the engagement ring in your face.'

we smirk because we believe that synthetic happiness is not of the same quality as what we might call 'natural happiness.' what are these terms? natural happiness is what we get when we get what we wanted, and synthetic happiness is what we make when we don't get what we wanted. and in our society, we have a strong belief that synthetic happiness is of an inferior kind. why do we have that belief? well, it's very simple. what kind of economic engine would keep churning if we believed that not getting what we want could make us just as happy as getting it?

with all apologies to my friend matthieu ricard, a shopping mall full of zen monks is not going to be particularly profitable because they don't want stuff enough. i want to suggest to you that synthetic happiness is every bit as real and enduring as the kind of happiness you stumble upon when you get e_actly what you were aiming for. now, i'm a scientist, so i'm going to do this not with rhetoric, but by marinating you in a little bit of data.

let me first show you an e_perimental paradigm that is used to demonstrate the synthesis of happiness among regular old folks. and this isn't mine. this is a 50-year-old paradigm called the 'free choice paradigm.' it's very simple. you bring in, say, si_ objects, and you ask a subject to rank them from the most to the least liked. in this case, because the e_periment i'm going to tell you about uses them, these are monet prints. so, everybody can rank these monet prints from the one they like the most, to the one they like the least. now we give you a choice: 'we happen to have some e_tra prints in the closet. we're going to give you one as your prize to take home. we happen to have number three and number four,' we tell the subject. this is a bit of a difficult choice, because neither one is preferred strongly to the other, but naturally, people tend to pick number three because they liked it a little better than number four.

sometime later -- it could be 15 minutes; it could be 15 days -- the same stimuli are put before the subject, and the subject is asked to re-rank the stimuli. 'tell us how much you like them now.' what happens? watch as happiness is synthesized. this is the result that has been replicated over and over again. you're watching happiness be synthesized. would you like to see it again? happiness! 'the one i got is really better than i thought! that other one i didn't get sucks!' (laughter) that's the synthesis of happiness.

now what's the right response to that? 'yeah, right!' now, here's the e_periment we did, and i would hope this is going to convince you that 'yeah, right!' was not the right response.

we did this e_periment with a group of patients who had anterograde amnesia. these are hospitalized patients. most of them have korsakoff's syndrome, a polyneuritic psychosis that -- they drank way too much, and they can't make new memories. ok? they remember their childhood, but if you walk in and introduce yourself, and then leave the room, when you come back, they don't know who you are.

we took our monet prints to the hospital. and we asked these patients to rank them from the one they liked the most to the one they liked the least. we then gave them the choice between number three and number four. like everybody else, they said, 'gee, thanks doc! that's great! i could use a new print. i'll take number three.' we e_plained we would have number three mailed to them. we gathered up our materials and we went out of the room, and counted to a half hour. back into the room, we say, 'hi, we're back.' the patients, bless them, say, 'ah, doc, i'm sorry, i've got a memory problem; that's why i'm here. if i've met you before, i don't remember.' 'really, jim, you don't remember? i was just here with the monet prints?' 'sorry, doc, i just don't have a clue.' 'no problem, jim. all i want you to do is rank these for me from the one you like the most to the one you like the least.'

what do they do? well, let's first check and make sure they're really amnesiac. we ask these amnesiac patients to tell us which one they own, which one they chose last time, which one is theirs. and what we find is amnesiac patients just guess. these are normal controls, where if i did this with you, all of you would know which print you chose. but if i do this with amnesiac patients, they don't have a clue. they can't pick their print out of a lineup.

here's what normal controls do: they synthesize happiness. right? this is the change in liking score, the change from the first time they ranked to the second time they ranked. normal controls show -- that was the magic i showed you; now i'm showing it to you in graphical form -- 'the one i own is better than i thought. the one i didn't own, the one i left behind, is not as good as i thought.' amnesiacs do e_actly the same thing. think about this result.

these people like better the one they own, but they don't know they own it. 'yeah, right' is not the right response! what these people did when they synthesized happiness is they really, truly changed their affective, hedonic, aesthetic reactions to that poster. they're not just saying it because they own it, because they don't know they own it.

now, when psychologists show you bars, you know that they are showing you averages of lots of people. and yet, all of us have this psychological immune system, this capacity to synthesize happiness, but some of us do this trick better than others. and some situations allow anybody to do it more effectively than other situations do. it turns out that freedom -- the ability to make up your mind and change your mind -- is the friend of natural happiness, because it allows you to choose among all those delicious futures and find the one that you would most enjoy. but freedom to choose -- to change and make up your mind -- is the enemy of synthetic happiness. and i'm going to show you why.

dilbert already knows, of course. you're reading the cartoon as i'm talking. 'dogbert's tech support. how may i abuse you?' 'my printer prints a blank page after every document.' 'why would you complain about getting free paper?' 'free? aren't you just giving me my own paper?' 'egad, man! look at the quality of the free paper compared to your lousy regular paper! only a fool or a liar would say that they look the same!' 'ah! now that you mention it, it does seem a little silkier!' 'what are you doing?' 'i'm helping people accept the things they cannot change.' indeed.

the psychological immune system works best when we are totally stuck, when we are trapped. this is the difference between dating and marriage, right? i mean, you go out on a date with a guy, and he picks his nose; you don't go out on another date. you're married to a guy and he picks his nose? yeah, he has a heart of gold; don't touch the fruitcake. right? (laughter) you find a way to be happy with what's happened. now what i want to show you is that people don't know this about themselves, and not knowing this can work to our supreme disadvantage.

here's an e_periment we did at harvard. we created a photography course, a black-and-white photography course, and we allowed students to come in and learn how to use a darkroom. so we gave them cameras; they went around campus; they took 12 pictures of their favorite professors and their dorm room and their dog, and all the other things they wanted to have harvard memories of. they bring us the camera; we make up a contact sheet; they figure out which are the two best pictures; and we now spend si_ hours teaching them about darkrooms. and they blow two of them up, and they have two gorgeous eight-by-10 glossies of meaningful things to them, and we say, 'which one would you like to give up?' they say, 'i have to give one up?' 'oh, yes. we need one as evidence of the class project. so you have to give me one. you have to make a choice. you get to keep one, and i get to keep one.'

now, there are two conditions in this e_periment. in one case, the students are told, 'but you know, if you want to change your mind, i'll always have the other one here, and in the ne_t four days, before i actually mail it to headquarters, i'll be glad to' -- (laughter) -- yeah, 'headquarters' -- 'i'll be glad to swap it out with you. in fact, i'll come to your dorm room and give -- just give me an email. better yet, i'll check with you. you ever want to change your mind, it's totally returnable.' the other half of the students are told e_actly the opposite: 'make your choice. and by the way, the mail is going out, gosh, in two minutes, to england. your picture will be winging its way over the atlantic. you will never see it again.' now, half of the students in each of these conditions are asked to make predictions about how much they're going to come to like the picture that they keep and the picture they leave behind. other students are just sent back to their little dorm rooms and they are measured over the ne_t three to si_ days on their liking, satisfaction with the pictures. and look at what we find.

first of all, here's what students think is going to happen. they think they're going to maybe come to like the picture they chose a little more than the one they left behind, but these are not statistically significant differences. it's a very small increase, and it doesn't much matter whether they were in the reversible or irreversible condition.

wrong-o. bad simulators. because here's what's really happening. both right before the swap and five days later, people who are stuck with that picture, who have no choice, who can never change their mind, like it a lot! and people who are deliberating -- 'should i return it? have i gotten the right one? maybe this isn't the good one? maybe i left the good one?' -- have killed themselves. they don't like their picture, and in fact even after the opportunity to swap has e_pired, they still don't like their picture. why? because the reversible condition is not conducive to the synthesis of happiness.

so here's the final piece of this e_periment. we bring in a whole new group of naive harvard students and we say, 'you know, we're doing a photography course, and we can do it one of two ways. we could do it so that when you take the two pictures, you'd have four days to change your mind, or we're doing another course where you take the two pictures and you make up your mind right away and you can never change it. which course would you like to be in?' duh! 66 percent of the students, two-thirds, prefer to be in the course where they have the opportunity to change their mind. hello? 66 percent of the students choose to be in the course in which they will ultimately be deeply dissatisfied with the picture. because they do not know the conditions under which synthetic happiness grows.

the bard said everything best, of course, and he's making my point here but he's making it hyperbolically: ''tis nothing good or bad / but thinking makes it so.' it's nice poetry, but that can't e_actly be right. is there really nothing good or bad? is it really the case that gall bladder surgery and a trip to paris are just the same thing? that seems like a one-question iq test. they can't be e_actly the same.

in more turgid prose, but closer to the truth, was the father of modern capitalism, adam smith, and he said this. this is worth contemplating: 'the great source of both the misery and disorders of human life seems to arise from overrating the difference between one permanent situation and another ... some of these situations may, no doubt, deserve to be preferred to others, but none of them can deserve to be pursued with that passionate ardor which drives us to violate the rules either of prudence or of justice, or to corrupt the future tranquility of our minds, either by shame from the remembrance of our own folly, or by remorse for the horror of our own injustice.' in other words: yes, some things are better than others.

we should have preferences that lead us into one future over another. but when those preferences drive us too hard and too fast because we have overrated the difference between these futures, we are at risk. when our ambition is bounded, it leads us to work joyfully. when our ambition is unbounded, it leads us to lie, to cheat, to steal, to hurt others, to sacrifice things of real value. when our fears are bounded, we're prudent; we're cautious; we're thoughtful. when our fears are unbounded and overblown, we're reckless, and we're cowardly.

the lesson i want to leave you with from these data is that our longings and our worries are both to some degree overblown, because we have within us the capacity to manufacture the very commodity we are constantly chasing when we choose e_perience.

thank you.

第8篇 ted英语演讲稿：为什么节食减肥没效果？

简介：在美国，80%的女孩在她们10岁的时候便开始节食。神经学家sandra aamodt结合自己的亲身经历，讲述大脑是如何控制我们的身体的。节食减肥为何没效果?来听听她的说法吧!

three and a half years ago, i made one of the best decisions of my life. as my new year's resolution, i gave up dieting, stopped worrying about my weight, and learned to eat mindfully. now i eat whenever i'm hungry, and i've lost 10 pounds.

this was me at age 13, when i started my first diet. i look at that picture now, and i think, you did not need a diet, you needed a fashion consult. (laughter) but i thought i needed to lose weight, and when i gained it back, of course i blamed myself. and for the ne_t three decades, i was on and off various diets. no matter what i tried, the weight i'd lost always came back. i'm sure many of you know the feeling.

as a neuroscientist, i wondered, why is this so hard? obviously, how much you weigh depends on how much you eat and how much energy you burn. what most people don't realize is that hunger and energy use are controlled by the brain, mostly without your awareness. your brain does a lot of its work behind the scenes, and that is a good thing, because your conscious mind -- how do we put this politely? -- it's easily distracted. it's good that you don't have to remember to breathe when you get caught up in a movie. you don't forget how to walk because you're thinking about what to have for dinner.

your brain also has its own sense of what you should weigh, no matter what you consciously believe. this is called your set point, but that's a misleading term, because it's actually a range of about 10 or 15 pounds. you can use lifestyle choices to move your weight up and down within that range, but it's much, much harder to stay outside of it. the hypothalamus, the part of the brain that regulates body weight, there are more than a dozen chemical signals in the brain that tell your body to gain weight, more than another dozen that tell your body to lose it, and the system works like a thermostat, responding to signals from the body by adjusting hunger, activity and metabolism, to keep your weight stable as conditions change. that's what a thermostat does, right? it keeps the temperature in your house the same as the weather changes outside. now you can try to change the temperature in your house by opening a window in the winter, but that's not going to change the setting on the thermostat, which will respond by kicking on the furnace to warm the place back up.

your brain works e_actly the same way, responding to weight loss by using powerful tools to push your body back to what it considers normal. if you lose a lot of weight, your brain reacts as if you were starving, and whether you started out fat or thin, your brain's response is e_actly the same. we would love to think that your brain could tell whether you need to lose weight or not, but it can't. if you do lose a lot of weight, you become hungry, and your muscles burn less energy. dr. rudy leibel of columbia university has found that people who have lost 10 percent of their body weight burn 250 to 400 calories less because their metabolism is suppressed. that's a lot of food. this means that a successful dieter must eat this much less forever than someone of the same weight who has always been thin.

from an evolutionary perspective, your body's resistance to weight loss makes sense. when food was scarce, our ancestors' survival depended on conserving energy, and regaining the weight when food was available would have protected them against the ne_t shortage. over the course of human history, starvation has been a much bigger problem than overeating. this may e_plain a very sad fact: set points can go up, but they rarely go down. now, if your mother ever mentioned that life is not fair, this is the kind of thing she was talking about. (laughter) successful dieting doesn't lower your set point. even after you've kept the weight off for as long as seven years, your brain keeps trying to make you gain it back. if that weight loss had been due to a long famine, that would be a sensible response. in our modern world of drive-thru burgers, it's not working out so well for many of us. that difference between our ancestral past and our abundant present is the reason that dr. yoni freedhoff of the university of ottawa would like to take some of his patients back to a time when food was less available, and it's also the reason that changing the food environment is really going to be the most effective solution to obesity.

sadly, a temporary weight gain can become permanent. if you stay at a high weight for too long, probably a matter of years for most of us, your brain may decide that that's the new normal.

psychologists classify eaters into two groups, those who rely on their hunger and those who try to control their eating through willpower, like most dieters. let's call them intuitive eaters and controlled eaters. the interesting thing is that intuitive eaters are less likely to be overweight, and they spend less time thinking about food. controlled eaters are more vulnerable to overeating in response to advertising, super-sizing, and the all-you-can-eat buffet. and a small indulgence, like eating one scoop of ice cream, is more likely to lead to a food binge in controlled eaters. children are especially vulnerable to this cycle of dieting and then binging.

several long-term studies have shown that girls who diet in their early teenage years are three times more likely to become overweight five years later, even if they started at a normal weight, and all of these studies found that the same factors that predicted weight gain also predicted the development of eating disorders. the other factor, by the way, those of you who are parents, was being teased by family members about their weight. so don't do that. (laughter)

i left almost all my graphs at home, but i couldn't resist throwing in just this one, because i'm a geek, and that's how i roll. (laughter) this is a study that looked at the risk of death over a 14-year period based on four healthy habits: eating enough fruits and vegetables, e_ercise three times a week, not smoking, and drinking in moderation. let's start by looking at the normal weight people in the study. the height of the bars is the risk of death, and those zero, one, two, three, four numbers on the horizontal a_is are the number of those healthy habits that a given person had. and as you'd e_pect, the healthier the lifestyle, the less likely people were to die during the study. now let's look at what happens in overweight people.

the ones that had no healthy habits had a higher risk of death. adding just one healthy habit pulls overweight people back into the normal range. for obese people with no healthy habits, the risk is very high, seven times higher than the healthiest groups in the study. but a healthy lifestyle helps obese people too. in fact, if you look only at the group with all four healthy habits, you can see that weight makes very little difference. you can take control of your health by taking control of your lifestyle, even if you can't lose weight and keep it off.

diets don't have very much reliability. five years after a diet, most people have regained the weight. forty percent of them have gained even more. if you think about this, the typical outcome of dieting is that you're more likely to gain weight in the long run than to lose it.

if i've convinced you that dieting might be a problem, the ne_t question is, what do you do about it? and my answer, in a word, is mindfulness. i'm not saying you need to learn to meditate or take up yoga. i'm talking about mindful eating: learning to understand your body's signals so that you eat when you're hungry and stop when you're full, because a lot of weight gain boils down to eating when you're not hungry. how do you do it? give yourself permission to eat as much as you want, and then work on figuring out what makes your body feel good. sit down to regular meals without distractions. think about how your body feels when you start to eat and when you stop, and let your hunger decide when you should be done. it took about a year for me to learn this, but it's really been worth it. i am so much more rela_ed around food than i have ever been in my life. i often don't think about it. i forget we have chocolate in the house. it's like aliens have taken over my brain. it's just completely different. i should say that this approach to eating probably won't make you lose weight unless you often eat when you're not hungry, but doctors don't know of any approach that makes significant weight loss in a lot of people, and that is why a lot of people are now focusing on preventing weight gain instead of promoting weight loss. let's face it: if diets worked, we'd all be thin already. (laughter)

why do we keep doing the same thing and e_pecting different results? diets may seem harmless, but they actually do a lot of collateral damage. at worst, they ruin lives: weight obsession leads to eating disorders, especially in young kids. in the u.s., we have 80 percent of 10-year-old girls say they've been on a diet. our daughters have learned to measure their worth by the wrong scale. even at its best, dieting is a waste of time and energy. it takes willpower which you could be using to help your kids with their homework or to finish that important work project, and because willpower is limited, any strategy that relies on its consistent application is pretty much guaranteed to eventually fail you when your attention moves on to something else.

let me leave you with one last thought. what if we told all those dieting girls that it's okay to eat when they're hungry? what if we taught them to work with their appetite instead of fearing it? i think most of them would be happier and healthier, and as adults, many of them would probably be thinner. i wish someone had told me that back when i was 13.

thanks.

第9篇 我们为什么要上学演讲稿

我们为什么要上学呢?以下是小编整理了关于我们为什么要上学演讲稿，希望你喜欢。

我们为什么要上学

嗨，大家好!你们今天过得怎么样?我现在和弗吉尼亚州阿林顿郡韦克菲尔德高中的学生们在一起，全国各地也有从幼儿园到高三的众多学生们通过电视关注这里，我很高兴你们能共同分享这一时刻。

我知道，对你们中的许多人来说，今天是开学的第一天，你们中的有一些刚刚进入幼儿园或升上初高中，对你们来说，这是在新学校的第一天，因此，假如你们感到有些紧张，那也是很正常的。我想也会有许多毕业班的学生们正自信满满地准备最后一年的冲刺。不过，我想无论你有多大、在读哪个年级，许多人都打心底里希望现在还在放暑假，以及今天不用那么早起床。

我可以理解这份心情。小时候，我们家在印度尼西亚住过几年，而我妈妈没钱送我去其他美国孩子们上学的地方去读书，因此她决定自己给我上课——时间是每周一到周五的凌晨4点半。

显然，我不怎么喜欢那么早就爬起来，很多时候，我就这么在厨房的桌子前睡着了。每当我埋怨的时候，我妈总会用同一副表情看着我说：“小鬼，你以为教你我就很轻松?”

所以，我可以理解你们中的许多人对于开学还需要时间来调整和适应，但今天我站在这里，是为了和你们谈一些重要的事情。我要和你们谈一谈你们每个人的教育，以及在新的学年里，你们应当做些什么。

我做过许多关于教育的讲话，也常常用到“责任”这个词。

我谈到过教师们有责任激励和启迪你们，督促你们学习。

我谈到过家长们有责任看管你们认真学习、完成作业，不要成天只会看电视或打游戏机。

我也很多次谈到过政府有责任设定高标准严要求、协助老师和校长们的工作，改变在有些学校里学生得不到应有的学习机会的现状。

但哪怕这一切都达到最好，哪怕我们有最尽职的教师、最好的家长、和最优秀的学校，假如你们不去履行自己的责任的话，那么这一切努力都会白费。——除非你每天准时去上学、除非你认真地听老师讲课、除非你把父母、长辈和其他大人们说的话放在心上、除非你肯付出成功所必需的努力，否则这一切都会失去意义。

而这就是我今天讲话的主题：对于自己的教育，你们中每一个人的责任。首先，我想谈谈你们对于自己有什么责任。

你们中的每一个人都会有自己擅长的东西，每一个人都是有用之材，而发现自己的才能是什么，就是你们要对自己担起的责任。教育给你们提供了发现自己才能的机会。

或许你能写出优美的文字——甚至有一天能让那些文字出现在书籍和报刊上——但假如不在英语课上经常练习写作，你不会发现自己有这样的天赋;或许你能成为一个发明家、创造家——甚至设计出像今天的iphone一样流行的产品，或研制出新的药物与疫苗——但假如不在自然科学课程上做上几次实验，你不会知道自己有这样的天赋;或许你能成为一名议员或最高法院法官，但假如你不去加入什么学生会或参加几次辩论赛，你也不会发现自己的才能。

而且，我可以向你保证，不管你将来想要做什么，你都需要相应的教育。——你想当名医生、当名教师或当名警官?你想成为护士、成为建筑设计师、律师或军人?无论你选择哪一种职业，良好的教育都必不可少，这世上不存在不把书念完就能拿到好工作的美梦，任何工作，都需要你的汗水、训练与学习。

不仅仅对于你们个人的未来有重要意义，你们的教育如何也会对这个国家、乃至世界的未来产生重要影响。今天 你们在学校中学习的内容，将会决定我们整个国家在未来迎接重大挑战时的表现。

你们需要在数理科学课程上学习的知识和技能，去治疗癌症、艾滋那样的疾病，和解决我们面临的能源问题与环境问题;你们需要在历史社科课程上培养出的观察力与判断力，来减轻和消除无家可归与贫困、犯罪问题和各种歧视，让这个国家变得更加公平和自由;你们需要在各类课程中逐渐累积和发展出来的创新意识和思维，去创业和建立新的公司与企业，来制造就业机会和推动经济的增长。

我们需要你们中的每一个人都培养和发展自己的天赋、技能和才智，来解决我们所面对的最困难的问题。假如你不这么做——假如你放弃学习——那么你不仅是放弃了自己，也是放弃了你的国家。

当然，我明白，读好书并不总是件容易的事。我知道你们中的许多人在生活中面临着各种各样的问题，很难把精力集中在专心读书之上。

我知道你们的感受。我父亲在我两岁时就离开了家庭，是母亲一人将我们拉扯大，有时她付不起帐单，有时我们得不到其他孩子们都有的东西，有时我会想，假如父亲在该多好，有时我会感到孤独无助，与周围的环境格格不入。

因此我并不总是能专心学习，我做过许多自己觉得丢脸的事情，也惹出过许多不该惹的麻烦，我的生活岌岌可危，随时可能急转直下。

但我很幸运。我在许多事上都得到了重来的机会，我得到了去大学读法学院、实现自己梦想的机会。我的妻子——现在得叫她第一夫人米歇尔.奥巴马了——也有着相似的人生故事，她的父母都没读过大学，也没有什么财产，但他们和她都辛勤工作，好让她有机会去这个国家最优秀的学校读书。

你们中有些人可能没有这些有利条件，或许你的生活中没有能为你提供帮助和支持的长辈，或许你的某个家长没有工作、经济拮据，或许你住的社区不那么安全，或许你认识一些会对你产生不良影响的朋友，等等。

但归根结底，你的生活状况——你的长相、出身、经济条件、家庭氛围——都不是疏忽学业和态度恶劣的借口，这些不是你去跟老师顶嘴、逃课、或是辍学的借口，这些不是你不好好读书的借口。

你的未来，并不取决于你现在的生活有多好或多坏。没有人为你编排好你的命运，在美国，你的命运由你自己书写，你的未来由你自己掌握。

而在这片土地上的每个地方，千千万万和你一样的年轻人正是这样在书写着自己的命运。

例如德克萨斯州罗马市的贾斯敏.佩雷兹(jazmin perez)。刚进学校时，她根本不会说英语，她住的地方几乎没人上过大学，她的父母也没有受过高等教育，但她努力学习，取得了优异的成绩，靠奖学金进入了布朗大学，如今正在攻读公共卫生专业的博士学位。

我还想起了加利福尼亚州洛斯拉图斯市的安多尼.舒尔兹(andoni schultz)，他从三岁起就开始与脑癌病魔做斗争，他熬过了一次次治疗与手术——其中一次影响了他的记忆，因此他得花出比常人多几百个小时的时间来完成学业，但他从不曾落下自己的功课。这个秋天，他要开始在大学读书了。

又比如在我的家乡，伊利诺斯州芝加哥市，身为孤儿的香特尔.史蒂夫(shantell steve)换过多次收养家庭，从小在治安很差的地区长大，但她努力争取到了在当地保健站工作的机会、发起了一个让青少年远离犯罪团伙的项目，很快，她也将以优异的成绩从中学毕业，去大学深造。

贾斯敏、安多尼和香特尔与你们并没有什么不同。和你们一样，他们也在生活中遭遇各种各样的困难与问题，但他们拒绝放弃，他们选择为自己的教育担起责任、给自己定下奋斗的目标。我希望你们中的每一个人，都能做得到这些。

因此，在今天，我号召你们每一个人都为自己的教育定下一个目标——并在之后，尽自己的一切努力去实现它。你的目标可以很简单，像是完成作业、认真听讲或每天阅读——或许你打算参加一些课外活动，或在社区做些志愿工作;或许你决定为那些因为长相或出身等等原因而受嘲弄或欺负的孩子做主、维护他们的权益，因为你和我一样，认为每个孩子都应该能有一个安全的学习环境;或许你认为该学着更好的照顾自己，来为将来的学习做准备……当然，除此之外，我希望你们都多多洗手、感到身体不舒服的时候要多在家休息，免得大家在秋冬感冒高发季节都得流感。

不管你决定做什么，我都希望你能坚持到底，绝不轻易放弃。

我知道有些时候，电视上播放的节目会让你产生这样那样的错觉，似乎你不需要付出多大的努力就能腰缠万贯、功成名就——你会认为只要会唱rap、会打篮球或参加个什么真人秀节目就能坐享其成，但现实是，你几乎没有可能走上其中任何一条道路。

因为，成功是件难事。你不可能对要读的每门课程都兴趣盎然，你不可能和每名带课教师都相处顺利，你也不可能每次都遇上看起来和现实生活有关的作业。而且，并不是每件事，你都能在头一次尝试时获得成功。

但那没有关系。因为在这个世界上，最最成功的人们往往也经历过最多的失败。j.k.罗琳的第一本《哈利.波特》被出版商拒绝了十二次才最终出版;迈克尔.乔丹上高中时被学校的篮球队刷了下来，在他的职业生涯里，他输了几百场比赛、投失过几千次射篮，知道他是怎么说的吗?“我一生不停地失败、失败再失败，这就是我现在成功的原因。”

他们的成功，源于他们明白人不能让失败左右自己——而是要从中吸取经验。从失败中，你可以明白下一次自己可以做出怎样的改变;假如你惹了什么麻烦，那并不说明你就是个捣蛋贵，而是在提醒你，在将来要对自己有更严格的要求;假如你考了个低分，那并不说明你就比别人笨，而是在告诉你，自己得在学习上花更多的时间。

没有哪一个人一生出来就擅长做什么事情的，只有努力才能培养出技能。任何人都不是在第一次接触一项体育运动时就成为校队的代表，任何人都不是在第一次唱一首歌时就找准每一个音，一切都需要熟能生巧。对于学业也是一样，你或许要反复运算才能解出一道数学题的正确答案，你或许需要读一段文字好几遍才能理解它的意思，你或许得把论文改上好几次才能符合提交的标准。这都是很正常的。

不要害怕提问。不要不敢向他人求助。——我每天都在这么做。求助并不是软弱的表现，恰恰相反，它说明你有勇气承认自己的不足、并愿意去学习新的知识。所以，有不懂时，就向大人们求助吧——找个你信得过的对象，例如父母、长辈、老师、教练或辅导员——让他们帮助你向目标前进。

你要记住，哪怕你表现不好、哪怕你失去信心、哪怕你觉得身边的人都已经放弃了你——永远不要自己放弃自己。因为当你放弃自己的时候，你也放弃了自己的国家。

美国不是一个人们遭遇困难就轻易放弃的国度，在这个国家，人们坚持到底、人们加倍努力，为了他们所热爱的国度，每一个人都尽着自己最大的努力，不会给自己留任何余地。

250年前，有一群和你们一样的学生，他们之后奋起努力、用一场革命最终造就了这个国家;75年前，有一群和你们一样的学生，他们之后战胜了大萧条、赢得了二战;就在20__年前，和你们一样的学生们，他们后来创立了google、twitter和facebook，改变了我们人与人之间沟通的方式。

因此，今天我想要问你们，你们会做出什么样的贡献?你们将解决什么样的难题?你们能发现什么样的事物?二十、五十或百年之后，假如那时的美国总统也来做一次开学演讲的话，他会怎样描述你们对这个国家所做的一切?

你们的家长、你们的老师和我，每一个人都在尽最大的努力，确保你们都能得到应有的教育来回答这些问题。例如我正在努力为你们提供更安全的教室、更多的书籍、更先进的设施与计算机。但你们也要担起自己的责任。因此我要求你们在今年能够认真起来，我要求你们尽心地去做自己着手的每一件事，我要求你们每一个人都有所成就。请不要让我们失望——不要让你的家人、你的国家和你自己失望。你们要成为我们骄傲，我知道，你们一定可以做到。

谢谢大家，上帝保佑你们，上帝保佑美国。

为什么上学

读书为了什么?读书,就像大人们所说的,考上名牌大学,最好再读个博士`硕士~~~那到文凭后,就能找到份好工作了.学好了知识,说不定还有几万年薪呢!总之一句话:找份好工作,养活自己和家人,把所学的知识变为财富.

怎样读书?这就是一个更值得思考的问题了,是三言两语所说不清楚的.读书,也是十分辛苦的.你读书读不好,老师天天找家长,家长天天又骂又打;如果读书读得好,那就更辛苦了,老师不愿放弃人才,要你学这学那的.爸妈望子成龙,望女成凤.早上,六年级了,怎么能去迟呢?起码要有大哥哥大姐姐的风范吗!6点多起床上学.一天下来,放学回家,先写作业,看会电视.又到了睡觉的时候.年复一年,日复一日.过得还行,可是一到重要的比赛的前夕,除了上语文`数学课,就得跟老师去补习.就像今年的数奥比赛,老师抓的特紧,什么电脑课`音乐课~~~想上没门.晚上作业写到10点,还真有点让人喘不过气来.但是,为了自己,也只能努力学习~~

读书为了什么?为了自己,为了爸妈.读书,有永远读不完的书. 记得还在大一时，一位同学仅仅因为考试成绩不理想而纵身从五楼跳下，结束了自己年轻的生命，也永远离开了医科大学这座美丽的校园。这件事对我的触动很大，他的匆匆离去至今仍深深地震撼着我。我常想：人人羡慕的“天之骄子”，老百姓眼里出类拔萃的莘莘学子们，心理为何如此脆弱?行动为何如此草率?这样的人，即便从学校毕业，他又怎能去面对人生路上的坎坎坷坷?怎能经受住社会上激烈的竞争?又怎能成为祖国新世纪的栋梁之才呢?如今，作为一名教师，我真想对这样的同学说：请珍惜您的生命，珍惜您的读书机会，珍惜祖国、人民、父母对您的殷切希望，放宽您的胸怀吧!读书不仅仅是为了学习，为了考试，也不仅仅是为了考分。读书为了什么呢?在强调“素质教育”的今天，认识读书的目的显得更为重要。长期以来，我们的学生所背负的压力过于沉重，读书目的过于单一，多年的应试教育，背负着父母、师长们沉重的爱和期望，读书的唯一目的就是为了取得好分数，毕业时能有张文凭，凭好分数找到满意的工 作单位，或是希望在社会上出人头地以致显亲扬名。在这种教育模式的禁锢下，学生往往忽略了自身各种能力的培养、素质的提高。正如一位科学家所说：中国学生太重收获，不重研究的过程。一旦结果不好，收获不丰，脆弱的心灵便无法承受。作为学生，努力学习，考出好成绩本无可非议，因为成绩毕竟是衡量学生学习效果的一种手段，但决不应是唯一的标准。众所周知，大学是一个进行“高等教育”的场所，是培养高素质人才的摇篮，学生们除了学习专业知识外，更重要的是要在思想道德素质、心理素质、身体素质和业务素质等各方面去充实和完善自我，这样，在迈出高校这座象牙塔之后，才能成为适应社会需要的高素质人才。我们敬爱的周恩来总理说过：“为中华之崛起而读书”，他那发自肺腑之豪言曾经响彻中华大地，无数人为之奋斗不息。今天，作为跨世纪的一代，作为祖国的未来和希望，我们肩负着建设祖国、振兴中华的重任，因此，我们今天提倡“素质教育”，决不仅仅是多开几门选修课，多听几个讲座，多看几次展览这么简单，而应该是由学校和她的师生们共同努力，用心血和汗水，用智慧和才能，用政策和行动，把大学办成高等人才的教育基地，让学生们在这片基地上沐浴着素质教育的雨露阳光，施展开拓自身的潜力和才华，从德、智、体、美各方面去充实和完善自我，成为国家建设、人民需要的有用之才，在祖国的建设中贡献自己的力量，为祖国的富强而奋斗，这，就是我们读书的目的!也是每一个新时代炎黄子孙所肩负的重任!

为什么要去上学

我知道，对你们中的许多人来说，今天是开学的第一天，你们中的有一些刚刚进入幼儿园或升上初高中，对你们来说，这是在新学校的第一天，因此，假如你们感到有些紧张，那也是很正常的。我想也会有许多毕业班的学生们正自信满满地准备最后一年的冲刺。不过，我想无论你有多大、在读哪个年级，许多人都打心底里希望现在还在放暑假，以及今天不用那么早起床。

我可以理解这份心情。小时候，我们家在印度尼西亚住过几年，而我妈妈没钱送我去其他美国孩子们上学的地方去读书，因此她决定自己给我上课——时间是每周一到周五的凌晨4点半。

显然，我不怎么喜欢那么早就爬起来，很多时候，我就这么在厨房的桌子前睡着了。每当我埋怨的时候，我妈总会用同一副表情看着我说：“小鬼，你以为教你我就很轻松?”

所以，我可以理解你们中的许多人对于开学还需要时间来调整和适应，但今天我站在这里，是为了和你们谈一些重要的事情。我要和你们谈一谈你们每个人的教育，以及在新的学年里，你们应当做些什么。

我做过许多关于教育的讲话，也常常用到“责任”这个词。

我谈到过教师们有责任激励和启迪你们，督促你们学习。

我谈到过家长们有责任看管你们认真学习、完成作业，不要成天只会看电视或打游戏机。

我也很多次谈到过政府有责任设定高标准严要求、协助老师和校长们的工作，改变在有些学校里学生得不到应有的学习机会的现状。

但哪怕这一切都达到最好，哪怕我们有最尽职的教师、最好的家长、和最优秀的学校，假如你因此我并不总是能专心学习，我做过许多自己觉得丢脸的事情，也惹出过许多不该惹的麻烦，我的生活岌岌可危，随时可能急转直下。

但我很幸运。我在许多事上都得到了重来的机会，我得到了去大学读法学院、实现自己梦想的机会。我的妻子——现在得叫她第一夫人米歇尔.奥巴马了——也有着相似的人生故事，她的父母都没读过大学，也没有什么财产，但他们和她都辛勤工作，好让她有机会去这个国家最优秀的学校读书。

你们中有些人可能没有这些有利条件，或许你的生活中没有能为你提供帮助和支持的长辈，或许你的某个家长没有工作、经济拮据，或许你住的社区不那么安全，或许你认识一些会对你产生不良影响的朋友，等等。

但归根结底，你的生活状况——你的长相、出身、经济条件、家庭氛围——都不是疏忽学业和态度恶劣的借口，这些不是你去跟老师顶嘴、逃课、或是辍学的借口，这些不是你不好好读书的借口。

第10篇 为什么要安全演讲稿

2022年1月9日凌晨5时左右，某水泥公司在进行清库时，因库内上部水泥结块掉落，出现严重塌方，9人掉进约30米高的水泥大罐中被掩埋，造成6人死亡，直接经济损失526万元。

安全制度是明灯，条条都是血写成。朋友们，你们看到了吗？6条生命的鲜血写下了大大的三个字“要安全”。

80%的事故都是“三违”引起的。不是违章指挥，就是违章操作，要么就是违反劳动纪律。

违章指挥的原因，就是藐视安全制度和法规。而违章操作，无外乎嫌麻烦、图省事、好逞强，一个很小的“疏忽”、一个不经意的“没事”、一个“以前都没事”这种习惯性违章的侥幸心理，导致了安全事故的发生，正所谓一失足，成千古恨。

有人问，为什么要安全？为了这6条鲜活的生命；为了这526万元直接经济损失和这无法估算的间接损失，所以，我们也要安全。

为什么要安全？你去问问千阳水泥公司2022年6月24日在检修机械设备故障时意外死亡职工李富生白发苍苍的老母亲吧，看看他在半夜里恶梦中惊醒时怎么回答你这个问题。

为什么要安全？你去问问2022年7月14日绍兴某水泥公司外包挖机驾驶员李家素的妻子吧，看看她砸烂了新婚购买的电视机、项链、耳环时，怎么哭着对你说。

朋友们，这一个个支离破碎的家庭，一具具冰冷的尸体，一双双哭红的眼睛，都在一次又一次地告诫我们：要安全。

2022 年 11 月 30 日下午,上海某公司值班长阿利在未佩戴安全帽与安全绳的情况下，擅自携带工具走上检修平台对正在运行的翻转行车进行维修，因扳手发生打滑，失去重心从 3.5 米高的检修平台坠落至水泥地面，后因伤势过重死亡。

为什么要安全？你就去问问这位38岁的值班长阿利吧。他会托梦告诉你，哥们，干活时还戴上安全帽、系上安全绳吧。有人说，不会给你托梦，那么你就去问问阿利13岁漂亮的女儿圆圆吧，她会抱着爸爸的相片哭着说，你们的同事和领导为什么没有一个人提醒你戴上安全帽、系上安全绳？爸爸，你们的同事和领导当时在干什么？他们去哪里了？为什么当时只有你一个人在干活？爸爸，你为什么那么傻？爸爸啊，咱们租住人家的房子又该交房费了，得交一年的，两万元。房东丽丽阿姨说，今年就不要一次缴清了，哪个月有了就哪个月缴。妈妈说，今年就不租了，换一家便宜一些的条件差一些的房子先住着，等我和弟弟长大挣钱了再买新房住。

为什么要安全？为了这两个可怜的孩子；为了那个哭得死去活来的妻子；为了李富生躺在病榻上不能动弹的老母亲。

为什么要安全？为了千千万万个李富生能够幸福地生活下去，当然也包括我们自己。

为什么要安全？为了践行______十九大报告中“以人民为中心”的这句暖心窝子的话。

为什么要安全？为了______那十句硬话之一：人命关天，发展决不能以人的生命为代价。这必须作为一条不可逾越的红线。

第11篇 奥巴马演讲稿《我们为什么要上学》经典语录

1、父母的责任是确保你做你该做的事，完成你的作业，而不是把所有空闲时间都用来看电视或玩_bo_.

2、每个人都有擅长的事情，每个人都能贡献些什么。所以你有责任发现自己的长处是什么，而学习就提供了这样一个发挥的机会。

3、也许你会是一个作家——能写书和在报纸上发表文章——但是如果你不完成英语课上布置给你的英语论文，你又怎么发现自己的才能？也许你会是一个发明家——可以设计出下一代iphone或是新药甚至是疫苗——但是如果你不完成自然课上的作业，你又怎能知道自己的潜能？也许你会成为市长，参议员或者最高法院大法官——但是如果你不参加学生会或辩论队，你又怎么了解自己的长处？

4、不管你将走上怎样的道路，我敢保证你都需要接受教育。

5、你生活的环境，你的样子，你从哪里来，你有多少钱，你的家庭怎么样，这些都不能成为你不做功课和不好好上学的借口。

6、你现在的处境并不能决定你将来也是这样。没人能决定你的命运，因为在美国，你要自己谱写自己的命运，你的将来由你自己创造。

7、不管你的目标是什么，我希望你们去做，去真正地付诸于行动。

8、成功是非常艰难的事。你不可能喜欢所有的课程，你不可能和所有的老师合拍，不是所有的作业看起来都和你现在的生活息息相关，而且你不可能，也不必要在第一次尝试时，就获得成功。

9、一些最成功的人同时也是失败次数最多的人。

10、你不能被失败打倒，你必须从失败中学习，如何在下一次做出改变。因此如果你陷入困境，那并不意味着你是倒霉蛋，那只说明你要加倍努力来走向成功。如果你成绩不好，那并不代表你很笨，只说明你需要花更多的时间在学习上。

11、没有人生来就是天才，只有熟能生巧。你不会在接触一项新运动时就进校队，你也不会在第一次唱歌时一点不走音，因此你需要练习。这个道理同样适用于学习。你也许要做好几遍才能答对一道数学题，你也许要读好几遍才能读懂文章，你一定要打好几遍草稿才能完成可以上交的论文。

12、不要害怕问问题，不要害怕在你需要的时候请求帮助，像我每天都在请求他人帮忙。助于人不是弱者的象征，恰恰相反是强者的特质，因为这说明你有勇气承认你在某方面的无知，而这能帮助你学到新知识。

13、当你挣扎，当你怯懦，甚至当你觉得大家都放弃你的时候，你千万不要放弃你自己，因为当你放弃你自己的时候，你也就放弃了你的国家。

第12篇 你为什么读大学演讲稿

本来是问同学们的，为什么要读大学？就很自然的想起，大概算起来已经有30年了，我是1978年考上大学。想起那时候为什么读大学，就是从一种苍白一下渴望读书，所以我们那时候的复习资料可不是像你们现在，有这么厚的，印刷很精美的复习资料，而是同学们用手在钢板上刻复习的提纲。我记得晚上印这个考卷，复习的卷子，印得最晚的时候，印到晚上三点。高考那一天，为了怕迟到，早晨5点钟就起床了，要步行10里赶到考场的地方。我记得那时候我们中午考完了以后，我们就坐在地上，所有的考生都吃一个干馒头，馒头里面就夹一点咸菜。第一次离开家庭，18岁，我到今天为止都记得，没有像你们今天读书有被套，当时所有的学生都要自己缝被子。我第一床被子缝了三个小时五十分钟，而且当中有无数次把自己的手指给扎破了。我觉得那个时候的艰苦是我最难忘的。我有时候在想，今天的幸福，今天一切一切为你们准备好的东西，到底是对你们今后的成才、成长是利多，还是弊多。实际在大学期间，多经受一些磨难、困难，哪怕是上一次邮局，哪怕是自己去寄一次钱，都是对自己的一种历练。

读大学到底是为什么？这句话一个五十岁左右的教授讲起来是容易的，但是对刚步入大学的青年来讲，我认为过高的要求是不现实的。我举个例子，现在经常爸爸教育自己的儿子，“儿子，谈恋爱可以，但是不能选女孩只选漂亮的，只要心灵美就是了”。我经常在想，这个孩子，这个同学的爸爸，我说你回去看看你妈长成什么样，你老爸在年轻的时候，不一样在找漂亮的吗。所以到了一定的年龄的时候，再过多去责备我们才步入大学生活的学生，甚至才有一点点人生履历的同学，我认为既不恰当也不公道。人生的目标，读大学，不是一下就悟到的，是要有一个过程。大学绝对不是让大家只学一门知识，如果要领会大学的学习，我认为最重要的不在于读哪一所名校。我今天当然知道，在座的同学当中有中国最著名的大学的学生，我忠心地希望大家，在大学期间一定要多去体会这所大学的历史和文化。

我在浙江大学执教已经快17年了，如果说把看钱塘江大潮，看西湖的美景作为浙江大学的荣耀，我说那是分文不值的。浙江大学应该真正珍惜的是从竺可桢老校长带领浙江大学的学生西迁几千里，在遵义的湄潭办学的那7年，树立的“求是”校风。所以我历来主张，大学的文化是应该有历史的积淀，而这样的积淀才是送给孩子们最珍贵的精神财富。北大、清华、北师大、复旦、交大、还有中国等等著名的大学，实际上都是有着丰富的文化内涵。说到这的时候，我要讲一句，难道贵州大学的孩子们就不能像北大清华，浙江大学的孩子们一样幸福吗？我们最近，让我们闪光、让我们自信的就是一位坚强的女孩，你们听说了吗？下肢截肢得了骨癌的女孩，十几次放疗，在生命最痛苦的时候竟然怀揣着对大学的梦想考上了重点线，我说这个孩子对贵州大学，对全中国大学生，她是无价之宝啊。所以我作为中国一个大学的校长，驱车到他的病床前，把那份珍贵的大学录取通知书送给了她，这位女孩叫什么，叫肖丽。我说贵州大学的同学们，贵大有了肖丽，从此贵大的学生就有了大写人生的光辉榜样，贵大有了肖丽，贵大的学生从此内心的情感和精神不应该再输给北大、清华、浙大！

我说这一段，今天是想把内心对在座同学们的殷切希望说给你们，实际上问一个人为什么要读大学，并不复杂。简单来讲，一定是在学的过程当中，去逐渐的体会你现在学的同学。甚至对专业的热爱也是如此，凡是付出的东西都会爱的，凡是得到太容易的东西，爱都不能持久。所以我现在倒是觉得我在我的高分子领域，是怎么爱的呢？恰恰是被逼出来的爱。我们班上成绩好的同学，当时都很时髦，一听physicalchemistry，就是物理化学，当时那个年代很神秘，班上成绩好的女同学，成绩好的男同学都往那选，结果轮到我们年纪小的同学，或者当时在班上不是特别优秀的同学选不到这个专业，我是被迫选了高分子的专业。结果，我告诉大家，就是这么一次逼迫，让我慢慢就爱上了高分子专业，而且是打心眼里爱。我在国外留学，为了拿这个博士学位，晚上做论文，一个星期基本上没见过阳光，都是在地下室的仪器旁边度过的，当我那天走出实验室的时候，人都是晃的。今天我有两句话送给在座的大学生朋友们：是因为我爱，我才付出的，但是更重要的是，恰恰是由于爱，我已经付出了，所以我必须更爱。

现在大学同学们的负担很重，甚至觉得喘不过气来了，你们受了一个错误的误导，以为在就业的时候，那些要审查你们的人，是不是在看你们的履历当中，写的你读的课程越多，就是越好。我今天给大家一个忠告：在读本科的时候，应该以精读，夯实专业基础和基本人文思想为最重要的目标，不要学得太满太多，先要夯实基本。这就如同武术，蹲马步、举杠铃，拉引体向上，你能够把自己这个身段，这个坯，就是这个材料的坯给塑造好，今后广阔的前程就等着你。而过早地患得患失去考虑所谓我专业今后要搞什么，有什么工作，什么工资，我认为都是一种短视，和不必要的心理负担。说到这的时候，我又要稍微说一句，就是现在媒体，或者个别的小报让我们的孩子们特别的沉重，说什么大学生找不到工作。我在浙江大学当了这么多年教授，我太了解了，全国多少单位需要我们浙江大学，北京大学，清华大学的孩子们去奉献，去真正的建功立业，但是我们的孩子们，真正去了需要的地方了吗？不是，是把自己挑剔的东西当成了第一位。所以我要告诉大家：不是找不到工作，是可能现在享受的工作你们不太容易找到，真正你们在座的想到贵州去，我现在就把你带走，机票我都给你们买好。所以我要讲，不是找不到工作，是享受的工作不太容易找，艰苦的工作你们不太愿意做。所以同学们整个大学期间，我希望你们简单一些，也纯洁一些，自然一些，用这样一种心态去面对大学生活，我自己的经验就是：一定给你带来学习的动力，生活的幸福感，和面对未来的一种幸福的憧憬和希望。

那么大学，还有什么同学们应该丰富的，我最推崇的就是文体，你们一定要喜爱艺术，喜爱体育，所以我现在特别教育现在的男孩，特别像我这种个的男孩，我一学声乐就感动了很多女孩，一般大家都认为我这种声音，起码都是1.85以上发出来的，像我这种身材，我打篮球不行吧，你知道我吗，我是浙江省高校乒协主席，浙江大学乒协主席，我今年53岁了，那为啥这么年轻呢？就是艺术和体育给我增加了活力，什么是最好的心灵教育？艺术。什么是最好的精神的培养？体育。让我们的男孩多去看看女同学柔美的小提琴，婀娜多姿的舞姿，我说过，要让女孩多到场上去看男同学打球，那种魁梧的身材，饱满的肌肉，那是什么？那是阳光，男人气。所以今天我要劝大家，为了健康快乐的学习，你们要到球场上去，要到音乐厅去，多听听优美的音乐，多看看激情洋溢的赛场，青春的活力就会迸发。我都在想，我多么渴望再以一个学生的身份再步入大学的校园，有些时候我作为一个长者，作为一个老师，在大学的校园，看到你们在那漫步，看到你们在那读书，我实际上内心是充满甜美的羡慕。现在我经常出席一些大学的总裁结业典礼，为什么有这么多的所谓财富的拥有者，他们集中在大学的校园，来重新地学习，这就是他们经过了人生的洗礼，甚至有了财富以后，对自己整个价值的重新反省。

如果今天回过头来，我把这样的话说给你们听，我就要告诉大家，怀揣一点理想，怀揣一点梦想，在大学的读书，你们一定会感知幸福的青年时代，谢谢大家！

第13篇 为什么要做卓越的医生演讲稿

大家好，我刚才讲脑血管病，也就脑中风这个病，它不分肤色，不分国度，不分年龄，也不分社会地位。我今年看到一个跟大家一样年龄的病人，19岁，大学三年级的学生。因为他本身学习的专业是传媒，可能晚上睡觉比较少，一点钟坐在自己的宿舍里边玩电脑，玩完电脑之后上厕所，可能待的时间比较长，等到在厕所从坐位突然变成直立位的时候，站起来的时候，突然一侧肢体偏瘫。她的母亲带着他到北京各个医院来就诊，后来到我的门诊，我们很快查到了原因，很快给这个孩子治疗了，他现在又重新回到了学校。所以今天的技术能够保证我们大多数脑血管病患者能够健康地回到原来的生活和岗位。

我做神经科医生三十五年了，我毕业那一年二十岁，毕了业分到那个单位，不是分在现在我这个专业，是在别的科室，后来那个主任说，我觉得你脑子挺好用的，你学神经科吧。因为脑子里边结构非常非常复杂，所有的学生毕业的时候不愿意学这个科室。我在神经科，我现在还记得当时写的第一份病历，就是解剖不知道，查体不知道，临床描述不知道，所以写完病历之后，主任来查房，拿着我的病历，我看表情就不太好，皱着眉头，后来抬起头来看了我一眼，把那个病历顺着窗户给我扔出去了。十几个大夫看着我，一个二十几岁的年轻人，你想那个心里受的打击是非常大的。肯定我做错事了，肯定病历写得不对，所以当时我印象非常深刻，流着眼泪出去捡那份病历。回来以后拿着病历，我实在看不出来哪个地方出了问题。等三个小时过去了，大家查完房都走了，主任走到我的旁边，跟我说了一句话，他那句话就是我热爱这个专业的开始。他说你不要以为我扔你的病历使你非常难堪，你不要以为上面错了几个字就是几个字，他说你知道有可能这一行字换来的是一个生命。所以我当时就觉得这个职业有可能跟生命关系这么近，我觉得我自己的职业一下变得崇高起来。所以从那天开始，我就下决心在这个专业不走了，一留就是三十五年。我那一年的时间，每天在办公室画脑神经的图，整整画了一年。

第二年我在那个地方当住院医的时候，看到了一个花季少女，十五岁，是我的病人。这个孩子上初中，她的妈妈说三个月之前开始四肢无力，等她到医院的时候四肢瘫痪，做了各种检查不知道什么病。我们高度怀疑是外周的肌肉上边病了，什么病呢，我就给她做了个活检，就在小腿上切了一块肌肉下来在显微镜下看，看着不正常，实在是不认识。之后我又到旁边医学院，因为医学院有电子显微镜，用电子显微镜再看，看着每一个肌肉细胞全跟别人长得不一样，但是也不知道叫什么，所以当时我就想，我说全中国谁看这个片子看得最好。那个年代，我知道北京301医院有一个老专家叫黄克维，黄克维教授是中国神经病理的最高的权威。所以我下了夜班，坐着四个小时火车到了北京，我拿片子给他看，他高度怀疑有一种病，他说我说不出名字来，他说你别走，我让我的学生下了门诊，给你复印文献。他的学生给我拿了一大厚本的英文复印好的文献给我，我看完之后，我知道那是一种非常非常特殊的病，叫线粒体糖原脂质累积病。那个病例是中国从来没有报道过的，是中国第一次发现这个病，我们找到病因，就肯定有办法去治疗了。我印象特别深，三个月之后，那个孩子又重新回到了学校。所以从这个病例，我才知道医生的每一步努力，可以使一个枯萎的生命重新地绽放，这是医生的最大价值。

三十五年以来，整个神经病学的技术在不断地进步，那么医生的经验也在不断地增长。所以今天我们再看病就不像以前那么困惑了，我们能用我们的知识帮助更多的人，去解决他的疾病和痛苦。很多学生问我，他说老师你看复杂病例的感觉是什么呢，尤其是不学医的同学可能更奇怪。医生看病是靠什么呢？我经常说，医生在门诊看病，他有时候像作家，为了要把一个故事线能够说清楚；有时候像导演,他需要重现当时那个病人疾病的场景；有时候又像个警察，像破案一样。所以如果你形象地讲一个医生怎么看病呢，医生就像现在戴了一个vr眼镜在看悬疑片的感觉。所以我们拿了一张ct，拿了一张核磁，需要你看到一个病灶，你要把那个平面变成3d的图像，之后你在3d图像上去解读，它现在对这个神经的损害能解释它的症状吗？能解释它的表现吗？能解释它的体征吗？如果解释不了，那肯定是诊断出了问题，而这个时候我刚才说又得像作家，又得看他从发病那天开始，每天的演变能够解读今天的后果吗，如果这个故事线你讲不通，那诊断肯定出问题了。

大家可能听着比较悬，我来讲一个病例就能够理解怎么样弄通这个故事了。几年前我看过的一个小伙子，二十几岁，他的症状，有一天在家里边突然出现炸裂似的头疼，这个头疼的感觉他自己形容是他一生中从来没有经历过的疼痛。那么到了当地的医院，当地医院做了个头的ct，告诉他脑袋里边出血了。二十几岁的一个孩子，脑袋里边出血是个很特殊的出血，是在脑的表面，医学叫蛛网膜下腔出血。如果按照一般的医学故事去讲，蛛网膜出血的百分之九十的原因是动脉瘤，就是动脉上鼓了一块瘤子出来。所以当地的医院很快给他做了一个脑血管造影，结果真的发现动脉瘤，他们就给做了手术，手术之后他就回家了，以为自己没有问题了。这个故事的后边就出了问题，一个月之后，他又再次出现炸裂似的头疼，他又回到那个医院，那个医院又做了ct，发现还是有血，他说又重新出血了，我们再做一个造影，造影发现这一次出了大问题，他不是一个动脉瘤，是五个动脉瘤。

他就到我的门诊找了我，到病房里面我就看他的病，大家注意，他从一个多月之后，从一个动脉瘤变成五个动脉瘤，这个故事造成的结果讲不通的，所以我就开始问他，你能告诉我在你病前的半年还有什么意外吗？还得过什么病吗？他突然想起来说，两个月前我受过一次伤，那我故事线要往前推两个月，我说你告诉我你怎么受的伤。他说他跟他父亲在一个餐馆吃饭，那个餐馆的旁边有人在打架，他站起来去劝架，被一个刀子误伤了上臂，他说当时伤得也不重，误伤了之后到医院包扎了一下，两个星期就好了，他说他没有在意。我说你好了之后，还有别的表现吗？他说那半个月老是在低烧，那我们这个故事线又重新从这一次的出血往前推两个月，把这个刀伤，那一次发烧，第一次动脉瘤，第二次动脉瘤连在一起。我要重新书写这个故事，我在办公室查文献，想了差不多两个小时，我站起来，我知道他的结论了。他是这一次刀扎之后有个细菌感染，他不知道，那个细菌顺着血管到了心脏，使心内膜感染，造成了感染性心内膜炎，所以他每次脱的不是一个东西，脱的是一团细菌，脱的脑子里面就腐蚀了血管，形成一个动脉瘤，脱到腐蚀一个动脉瘤。所以这就是医生看病的过程，他是靠这种逻辑的推理，他是靠把一个故事讲完整。这个病人就诊断清楚了，大家知道他最后是怎么治疗的吗？不学医的肯定不知道，非常简单，给他输了三个星期的消炎药。再复查，所有动脉瘤消失了。所以今天我们有越来越好的技术，今天我们有越来越好的这种检查手段，所以也有越来越好的医生。

医生怎么分类？我说我脑海中的医生应该分成四类。最低级的医生叫不合格的医生，或者叫培训中的医生，就像当年我大学毕业，病历被主任扔出去一样，那肯定是不合格，因为你没有学会，那这部分医生他不能保障患者的健康。比他再高一段的医生就是合格的医生，他能够按照指南，按照主任讲的，按照教科书讲的去看病，他会循规蹈矩。比他再高级的医生，我们称之为优秀的医生，所谓优秀的医生，那就是他能够把自己的经验，把自己的一些体会，把不同的病人能够区分开，也就是能个体化，他的病人的愈后比别人更好。每个患者都希望碰到优秀的医生，其实对我在医院工作三十五年的一个老医生来讲，我觉得医生还有更高的一个层次，这个层次叫卓越的医生。所谓卓越的医生，就是他除了能够把病人问题解决好，他同时还能创造新的理论，新的治疗方式，新的学说，新的手段，这样让更多的病人可以获益。在座的我不知道有没有学管理学的，管理学中有一个悖论，因为优秀所以难以卓越，优秀是卓越的大敌。中国现在有很多优秀的医生，但还是缺卓越的医生。

开讲啦王拥军演讲稿：为什么要做卓越的医生？（226期）

给大家讲一个故事，这故事到现在已经整整十年，到现在我还记得。2006年10月29日那一天下午六点多，天已经黑了，我一个人坐在家里的落地窗前，在沙发上不敢开灯，我心里非常紧张，因为那一天在开普顿开“世界卒中大会”，那个会上决定2022年的“世界卒中大会”到底在哪儿开。我的同事每十分钟给我打一次电话，每十分钟他告诉我选票情况，我当时想着如果中国真的能够获得主办权的话，对中国脑血管病的病人是一个巨大的福利，但是最后的结果很让我失望，七点多钟结果出来了，不是北京。后来有一位教授，一个德国教授跟我说，他们觉得北京会议条件很好，但是中国脑血管病的研究的成绩全世界看不到，这是十年前。那个时候我就想，中国缺很多国际大家关注的研究，所以那天晚上我一夜没有睡，我一直在想既然历史的责任把这么重的担子放我身上，我怎么能够让中国跟全世界走在同一条起跑线上。我们今天是为“健康中国”在呼吁，《“健康中国2030”规划纲要》里边，有两大段话在讲科技创新对于健康的支撑作用，因为没有新的科技手段，没有新的研究，没有新的证据，我们脑血管病的防控永远在困惑中旋转。所以我想中国在未来呼吁更多的卓越的医生去参与研究，让更多的卓越的医生找到新的治疗方法，能使中国的1100万脑血管病人早日摆脱痛苦。

所以《“健康中国2030”规划纲要》我在读完它之后，我还有第二点体会，未来的中国医疗要“强基层”，就是要让基层的医疗强大起来。我们大多数病人都是在基层，有一年我跟着我的同事去了甘肃的南部，那一年正好是甘南地震。是地震前几天我去的，从北京飞到兰州，从兰州坐了六个小时长途汽车到了甘南，下了车之后，我说我想找一个老人比较集中的地方，他们当地的同志带着我到了当地的敬老院。那个敬老院有四十位老人，我跟我的同事用了整整一下午跟他们在一起，问了四十个老人，我说你知道你的血压吗？没有一个人知道，没有量过，那些老人平均年龄差不多七十岁，从来没有量过血压。我说你知道你有脑中风的风险吗？他们不知道，他不知道这词，我说我带机器了，我给你查一下，四十位老人，发现有五位老人脑子里边已经出了亚临床病变，也就是他们这五位老人在未来的几年可能会得中风，但他自己不知道。有个姓王的老人，我现在还记得他的模样，个头比我矮一点，满头的白发，从我进到敬老院那天开始，他就站在距离我半米远的地方，跟个孩子是一样的，我走给别人看病，他跟着我，我去取东西他跟着我，我去上厕所他也在门口站着。等我下午五点钟收工了，我说我离开，我跟我的同事坐了一个中巴，我坐在最后一排，等车开出去的时候，我回了一下头，那老人跟着车在跑，所以那个时候心里很难受，我就知道基层多需要人去关心我们这高危的人群。他没有见过大夫，他不知道自己未来的命运有可能跟中风连在一起。所以“强基层”是我们解决“健康中国”非常非常重要的，它不是口号，它需要行动。我们同样也要提高我们全民的健康素养，让所有的老百姓能够有正确的健康知识，能够武装自己。

大家知道人和动物的区别在于脑的功能，所以换一句话来讲，人的本性就是脑的功能，所以当一个人脑子得病之后，脑血管出了问题，得了中风，他就失去了脑的功能。换一句话来讲，他就失去了人的本性。所以作为医生来讲，挽救脑的功能就是挽救人的本性，这就是三十五年来我能作为这个医生感到最自豪的地方，我们在为人的本性而战。谢谢大家。

第14篇 我们为什么要一起上大学演讲稿

很多人都说大学是进入社会前最重要的一部分。以下是小编为大家收集关于我们一起上大学的演讲稿，供你参考阅读。

我们为什么要上大学

绵阳中学的同学们，你们好!

我现在很紧张，印象里，我人生大概有两次极致的紧张。第一次是我高考的时候，因为我不知道我能不能考上大学。第二次是我几年前去清华和北大演讲，那是我根本不可能考上的两个学校，面对那些成绩优异的学霸，我很忐忑。

但后来我想通了。我读高中的时候不如别人，排名落后，输了同学一大步。但是进入社会之后，我很努力地工作，慢慢取得了成绩，走到今天，我可以大声地说一句，看，我并没有输。对我来说，人生不仅仅只有高考才是最重要的门槛，其实人生一段一段全都是槛。每个槛都要努力，都能努力，都有机会去努力。

今天想和大家说的题目是“我们为什么要考大学?”在写这篇文章的时候，免不了回忆过去，感慨万千，那是我不愿意回首的日子，因为它对我来说太黑暗了。

三年前《人民日报》发了新闻，说是一个父亲不想让自己的女儿读大学，因为他认为读大学要四年时间，一共要花掉八万的学费。读完之后找的工作可能一个月工资也就两三千块钱，他认为好不划算。那个父亲说我让我女儿高考之后直接去打工就好了，四年怎么着都可以赚个十几万吧。然后这十几万还可以创业、买房子、做投资，多好。

新闻一出来，人人哗然，大家开始疯狂讨论。

说句实话，如果那个时候我还在读高一或高二，我肯定会特别兴奋地拿着这张报纸给我爸妈看。我会说你们看，学学人家的爸爸，都不要他女儿读大学的，多棒。我还会跟他们说，你们别逼我考大学了，就让我早一点工作吧，提前给你们赚钱养老，早日实现我的价值，多好啊。

现在想起来，为什么高一、高二的我会这么认为呢?很大程度上是因为我根本不知道一个人为什么非要成绩好，成绩好不就是为了让老师开心，让爸妈有面子嘛，让七大姑八大姨羡慕，指指点点说瞧人家孩子多棒。但是这些，跟我有什么关系啊?

那时我特别羡慕一些同学，他们好像天生就特别会学习，小学前十名、初中前十名、高中前十名。他们应付考试不费吹灰之力，人家是一做就全对，我是一看都不会。我绞尽脑汁也做不出来的那些题目，他们微微一笑就知道答案了，完全用智商碾压了我。久而久之，在我心里认为，学习好、成绩好这件事情对我来说就是白日梦，而我的存在就是个笑话，就是为了衬托那些学习好的人。

从踏进校门开始，我就从来不知道成绩好到底是什么感觉。我认为自己完全不具备学习能力，那我为什么要强迫自己去考大学，让自己输个彻彻底底呢?

直到高三的时候，我有同学要去长沙的湖南师范大学考中国传媒大学的播音主持系，就问我说刘同你要不要去考?说实话我哪学过什么普通话啊?我普通话真的超烂的。但是我想反正高三了，我也不想考大学，闲着也是闲着，如果我跟着去考了，万一传媒大学的招生老师又聋又瞎呢?万一把我录取上不是挺好的。然后我就跟我妈说我想考播音系。我妈平时很抠门的，可这次二话不说就答应了，问我需要多少钱，我说500，我妈立刻就给我了。

我之前从来没有出过远门，更没有去过大学。但我就这么大着胆子去了。

事实证明中国传媒大学的招生老师不聋也不瞎，我初试就被淘汰了。我的那些同学都过了复试。

既然如此，我就干脆死了心，来都来了，那就在校园里随便转转呗。于是，在我同学去参加复试的时候，我就绕着整个大学城(由湖南大学、中南大学和湖南师范大学组成)，一点一点地逛。我看到那些风华正茂，意气风发的大学生们，结伴成群，一起弹吉他，一起唱歌，一起表演话剧，一起喝酒，一起去看电影，在英语角用英文随意聊天，在我眼里，大学就好像幸福自在的天堂一样。

在大学里，一个人可以参加很多社团，可以拥有很多朋友，拥有无限多的选择，拥有最大限度的自由。那几天，我看得眼花缭乱。这和我在初中高中单调压抑的校园生活完全不一样。甚至我还发现男生女生亲密地走在一起，别人也不会用异样的眼神看他们。我完全不能理解这是一个什么环境，难道大学都是这样的吗?

回去之后，我就一直想这个事情。我的家乡在湖南郴州，那是一个小得不起眼的城市，生活了十几年，我周围的同学和熟人都是一样的，我的亲戚朋友也是一样的。同样的面孔，同样的思维，同样的习惯，同样的言谈。生活圈子极其狭窄，我稍微有点事，立刻传得人尽皆知。人人都知道我的短板，都知道我成绩不好，所有人看见我必说的一句话就是，刘同你很难考上大学，你真的不是读书的料。

久而久之，我对这种环境生出极度的厌恶，周围所有人都在唱衰我，看不起我，每个人都认定，你，刘同，就这样了，这辈子都没什么出息了。

那时我有些破罐破摔的心理，我抵触所有人，抗拒所有人。我不是不想考大学，我只是太讨厌那些在我耳边叨叨着让我一定要好好学习的人，他们好像是情感的绑架者，以所谓的“用心良苦”，打着“为你好”的旗号，给我施加压力，不断灌输给我可怕的理念，考不上大学，一辈子就全完了。

从师大回去之后，我突然开窍了，眼前似乎打开了一扇门，通往一条从未见过的道路。我不再消极对抗，不再懈怠沉沦，我开始强烈地想尝试一种新的生活，我想认识更多有趣的人，而不是十几年来随时随地都会讽刺我的那些熟面孔。我也想去参加那些社团，接触全新的世界，全新的人群。我想摆脱父母的安排，不再由别人告诉我该如何去做。

那一刻，我幡然醒悟，仿佛被打通了任督二脉，整个人都亮堂了。我必须要靠自己的努力，走出去，看看外面的世界。如果我不考大学，留在这个小城，找份看得到尽头的工作，那我这辈子就真的全完了，我肯定被自己给堵死了。

那一刻，我突然明白了自己之前有多蠢。我花了那么多时间在跟成绩好的人较劲，好像我学习的目的，只是为了要争第一名、第二名、第三名，而我无论如何也争不到。我人生的全部挫败都来源于此，我所有的精力，思想，也都集中耗费于此。

我一直以为读书是为了父母，为了亲戚，为了老师，为了面子。但那一刻，我清楚地知道，考上大学，不为任何人，只是为了自己。为自己能够展翅高飞，离开一成不变的环境，飞到更高更远的地方，去认识更多更好更有趣更优秀的人。

我太晚才明白这个道理。但是，世上从来没有太迟的事。

从那天开始我拼命学习，我真的是从早上5点钟就起床，把高一、高二落下的功课全部从头看一遍，任何一个小问题都不放过，直到弄明白为止。每天晚上我都是两三点钟才睡觉，每天就睡几个小时，本来已经对我不抱任何希望的爸妈看到我这个样子，都认为我从长沙回来之后疯掉了。

他们当然不知道我心里怎么想的。那时我心心念念想的就是我一定要逃离他们，一定要离开，我多考一分就能离他们远一点，我多考十分就能离他们再远一点，如果有本事的话，我真恨不得自己考到国外去，永远都不回来。

去考中传播音系之前，我的成绩是班里倒数十名。最后高考的成绩出来，我让所有人大跌眼镜，比一模成绩高出一百多分，超水平发挥，考上了湖南师范大学的中文系。

进入大学之后，我每一天都练习写作，也开始认识更多的朋友，他们性格迥异，新鲜风趣，我跟他们分享读书的感受，尽情讨论对各种事物的看法。我整个人的状态一下子就变了，从高中时的颓废自卑压抑，变得阳光乐观热情。

我在大学里面认识了一个女同学，对我影响深远。那时因为我的钱老不够花，那个女同学总是特大方地借我钱，而且还不催着我还。我就很奇怪，打听之后才知道，原来她是特困生，有补助，还有特等奖学金，每个星期还去当家教，所以就显得很有钱的样子。

她的经历让我汗颜，而当我有一天在校报上看到她的专访，就彻底被她折服了。

她上小学的时候爸爸得骨癌去世。为了给爸爸治病，家里花光了所有的钱，还欠了一大笔债。她就跟妈妈商量，如果读完高中再读大学的话，开销太大，家里可能一辈子都还不上债，所以她要放弃考大学，选择读中专，这样可以提早几年出来工作。

她成绩非常好，考上了中专后顺利找到了一份小学老师的工作。正当家里一切慢慢好起来的时候，妈妈突然被诊断出来得了肌肉萎缩，丧失了自理能力。从那天开始，她每天早上7点钟去学校教书，晚上回来之后给妈妈按摩，缓解妈妈的疼痛，一直要按到下半夜，妈妈睡着之后她再去备课，睡两三个小时然后又去学校上课。就是这样一直扛一直扛，几个月、半年、一年。然后就在妈妈病情加重的时候，她所在的中专突然告诉她说，学校有五个名额，可以推荐去报考湖南师范大学，你要不要试一试。

在她的字典里，从来就没有“大学”这两个字，她认为自己这辈子与大学已经绝缘。而且，她的成绩不是五个人里最好的，她的综合条件也不是最优秀的，即便机会来了，也绝对轮不到她。

这件事她没有跟妈妈讲，但她还是悄悄去了湖南，到了长沙。因为她跟我一样，从来就没有去过省会，她只是想去见识一下。

没想到，她初试竟然过了，通知她二试的时候，她依然不敢抱任何希望。到了放榜那天，她在榜上看到了自己的名字，简直不敢相信自己的眼睛。她一路狂喜地坐大巴回家，想第一时间把这个好消息告诉妈妈。半途中bp机响了，医院给她发信息说请速回电。她立刻下车去电话亭打电话，医院说妈妈快不行了，她一边哭一边往医院奔去，赶到的时候妈妈已经去世了，她没来得及告诉妈妈这个好消息，妈妈到死都不知道女儿靠自己的努力考上了大学，实现了最不可能的心愿。

而她，虽然扭转了命运，可仍然没有逃过命运大神的捉弄，她成了孤儿。

听完这个女同学的故事，我的眼泪哗哗地流。她小小的个子，竟然肩挑背扛了那么沉重的负担。她每天笑嘻嘻地努力读书，生活，完全掩盖了深夜痛哭的眼泪和忧愁。

毕业后我们一起考进湖南卫视，在那之前她根本不知道电视台是做什么的。但她极其努力，比男孩子还肯拼，每天熬夜加班。两年之后我在湖南台还只是一个默默无闻的小记者，她已成为一个声名鹊起的大编导。

现在，她是光线传媒活动公司的总裁。

一起北漂的日子里，我曾经问她，你为什么那么拼啊?她说自从我爸妈离开我之后，我就知道这个世界上没有任何人会帮助我，我只能靠自己改变已经写好的命运。生命是一本可爱的书，既然已经翻开了，我就要认真地，积极地，从开头看到结束。

我要感谢自己在高中最后几个月的努力。如果当时选择了放弃，我不可能遇到这么优秀的人，又通过与她的相识改变了自己。读大学很重要的意义就是，遇见跟你一样努力的人，你们一起发光。

我转发《人民日报》那条新闻时，写了一段话。我说：读大学的价值也许在于能认识未来几十年最重要的朋友，能分辨哪些人自己一辈子都不会交往，能集中解决很多困惑，从而形成自己的原则，开始学会拒绝。读大学的价值在于你明白了世界上有很多优秀的人，你开始有了靠近他们的动力，读书不是为了拿文凭或者是为了发财，而是为了成为一个有温度、懂情趣、会思考的人。你现在努力，未来就会遇见那些和你一样努力的人，你现在不努力，你未来遇见的人大概也是和你一样的处境。

有很多人非常的幸运，从高中就知道自己喜欢什么。而我其实没有那么走运，我是通过短暂的努力进入大学之后，才给了自己一个机会重新塑造自己。

所以回到我们开始的话题，高考重要吗?当然重要，而且极其重要。

人生的道路上，未来还有很多坎，肯定比高考还要难，因为它们不如高考那么纯粹，那么公平，人人站在相同的起跑线上，面对同样的竞争环境，你单纯通过拼搏勤奋，就能获得优异的成绩。步入社会后，你会发现，很多事，即便努力了也是无效，因为种种条件的差异，社会的各种潜规则，你不再拥有公平竞争的机会。从此也再不会像高考这样，有一群同龄人和你一起战斗，有老师带着你们奋力向前，有家长在背后做你们的强大支援。

高考的可贵，就在于它的纯粹，所以一定要把握最后的时机，在最纯粹的竞争中，漂亮地尽力地拼搏一次。

绵阳中学的同学们，你们一定要好好读书，读书不是为了家长，也不是为了老师，而是为了让你们自己变得更优秀，变得更好，谢谢。

我的大学，我的梦

各位评委、亲爱的同学们：

大家好!送走了温暖的__年年，又迎来了期待的201_，如今我们已从一个满怀壮志的高中生，成为一名大学生，这期间虽然饱尝了山穷水尽疑无路的困顿，可丰富的大学生活又给我们带来了柳暗花明又一村的崭新境地，因为这里是我们攀登目标理想的新起点，这里也是我们积累知识阅历的新家园。

今天，我的演讲题目是“我的大学，我的梦!”

也许中学时期就已经读到或者听到许许多多关于大学生活的信息，有人说大学生活绚丽多彩的，也有人说大学生活是无聊空洞、浪费青春的。也许，后者更多一些。是的，其实，他们说的都是正确的，因为真实经历，他们才会那么说，这两者是不矛盾的。这是因为在大学里，有的人确实过得很充实、很开心，深深留恋这块他们认为是一辈子都无法重复的净土。也有的人，从一踏进校园就很失望，觉得一切都跟自己想像的不一样。从此浑浑噩噩混日子，最终醒悟的时候才猛然发觉，仿佛一夜之间，大学已经过去，随之逝去的还有自己宝贵的青春。记住，只有后悔大学混了几年的人，而不会有后悔上了大学的人。即使是那些在校时贬得他的母校犹如人间地狱的人，多年以后，回忆起大学时光，也往往会感慨万分，甚至泪流满面。不管你未来大学过得如何，至少你要时刻提醒自己：人生只有一个大学阶段。

在过去的旅途中，无论你是否拥有过欢笑，拥有个阳光，这都已成为永远的记忆，加上一把锁将它封闭起来吧!摆在我们面前的，新的老师，新的同学，新的旅途，新的梦幻，新的生命正在破土而出，面对这一切，我们该怎么办。由于现实的残酷，我们将化身为一个个骑士，抹掉胸口上的创伤，擦掉昔日的荣耀，拿上我们的曾经的利器，整装待发，新学期的目标是我们新的征途的开始!

梦想是我们通往成功的地图，只有付出了行动，迈出我们坚实的步伐才能让我们到达成功的彼岸。确定我们的目标，就要为了他努力拼搏。志当存高远!我们要立长志不要常立志。

人生是对理想的追求，理想是人生的指示灯，失去了这灯的作用，就会失去生活的勇气。因此，只有坚持远大的人生理想，才不会在生活的海洋中迷失方向。托尔斯泰将人生的理想分成一辈子的理想，一个阶段的理想，一年的理想，一个月的理想，甚至一天、一小时、一分钟的理想。当你听到这里，同学们，你是否想到了自己的理想?

人生的花季是生命的春天，它美丽，却短暂。作为一名大学生就应该在这一时期，努力学习，奋发向上，找到一片属于自己的天空。青年是祖国的希望，民族的未来。每个人主宰着自己的明天。

历史的重任在肩，我们责无旁贷。我们一定会勇敢地挑起肩上的责任，虽然前方会有巨浪滔天，但是也会有长虹贯日。让我们拿出“吹尽狂沙始到金”的毅力，拿出“直挂云帆济沧海”的勇气，去迎接人生中的风风雨雨!“宝剑锋从磨砺出，梅花香自苦寒来”，我坚信一分耕耘，一份收获，学习的根是苦的，学习的果子是甜的。我们奋发努力、勇往直前，一定会迎来收获的那一天。希望几年后的今天，我们能够收获自己辛勤劳作换来的累累硕果。同学们，今天让我们在一起定下大学之约，让我们告别盛夏的流火，应承金秋的丰硕，用青春诠释我们曾经的誓言，用汗水锻造我们明日的辉煌。未来的日子我们将共同走过，我们有着共同的追求。

大学生活是多姿多彩的，但也需要我们去把握和深人体会。有人说：“平凡的大学生有着相同的平凡，而不平凡的大学却有着各自的辉煌。”但，你可以选择平凡，但却不可以选择平庸;可以的话，相信谁都想不平凡。好了，我今天的演讲也到此为止了。最后，只上一句话：“路漫漫其修远兮，吾将上下而求索。”是的，送给我自己，也与大家共勉!

谢谢大家。

我要上大学

尊敬的各位领导﹑老师﹑家长们，亲爱的同学们：

大家好!欢迎大家的到来!

在这个炎炎夏日，我们相聚在临猗中学，欢送金榜题名的14届考生，激励冲刺高考的15届考生。高考，无疑是人生中至关重要的一次考试。在过去的一年里，经过我们教师和学生的共同努力，我临猗中学再创辉煌，又一次不负县领导和家乡父老的重托，把新一批的学子们送进了理想的大学。回顾过去，有汗水也有收获，有辛劳也有欢乐，看着考上大学的学生们绽放的笑脸，我们教师觉得一切的付出是那么的有价值!

对于步入高三的学生们，我们有很多期盼，很多祝福，但更多的是叮咛与嘱咐：面对高强度的训练，你不要惧怕;面对学习的辛劳，你不要退缩;面对屡次的失败，你不要气馁;压力很大，你要坚持努力不松懈;时间紧迫，你要争分惜秒不虚度;底子再差，你要奋斗拼搏争上游。一年的努力也许就可以换来一个更辉煌的前程，一个更理想的未来，人生没有几回搏，此时不搏何时搏!

同学们，高三虽然很辛苦但不要担心，不要害怕，因为我们在座的所有教师会陪你们一起努力，帮你们调整状态，帮你们争的高分，帮你们打好人生这一仗。因为你们赢就是我们赢，你们考上大学就是实现我们的理想。

最后，让我们一起向高考宣战，向人生宣战，战胜高考，赢得人生，让我们大声的喊出：“我要上大学!”

第15篇 我为什么要到升旗仪式上讲话演讲稿

我是初二9班的邓靖儒。今天，我讲话的题目是：我为什么到升旗仪式升上讲话？

上中附以来，我逐渐喜欢上升旗仪式，喜欢聆听同学们的升旗仪式讲话。大家的发言没有过多的大道理，都充满了个性的思维和表达，让人心中充满热情。不知什么时候，我冒出了一个念头：他们为什么要在升旗仪式讲话呢？

我深思了许久，最终我找到了结论——那就是追求成功的体验。我们都渴望成功，都想得到成功的秘诀，然而成功并非唾手可得。在通往成功的道路上，我们要经过许多挫折与失败，而勇气则是我们的精神支柱。

就举我的一次经历来说吧，一年前一次偶然的机会，我和同班的另一名同学被班主任推选为升旗仪式主持人，激动与焦虑交杂在心中。我既渴望这机会，也担心自己无法胜任。每天放学回家后，我就面对镜子反复练习，挺胸收腹，站姿挺直，面带微笑，直到喉咙发痒，腰部酸痛，双脚发麻，甚至自己都觉得面部肌肉因保持笑容而麻木。我也曾想过放弃，心想只要把学习搞好就行了，其它的都是“副业”、无关紧要。但看到我的同学做主持时那么轻松，享受，我就咬牙对自己说“既然选择了，就要坚持；别人行，我也行。”怀着这个信念，我走上了升旗仪式主持台。在台上，感觉一切都比较顺利，但中间我忘词了，我开始变得忐忑。稿子又不在身边，模模糊糊只想到几个相关联的词语，于是我灵机一动，将那些词用自己的话串连了起来，意思与原意差不多，总算没出尴尬。升旗仪式结束了，我松了口气，老师走过来说：“第一次主持还不错嘛”，我心中成功的喜悦油然而生。

上台演讲并不只是锻炼勇气和信心，还是一个和同学们交流的分享的好机会。比如说，可以分享对时政、各类社会事件的看法，以此引起同学们关注、了解世界变化和社会问题。当然，并不是都要谈国家大事，也可以谈自己感兴趣的话题，例如关于饭堂、篮球场使用、中学生服装等问题。这些虽是生活小事，但它能促使我们了解周边事物，引起思考，表达自己的立场。这也是一种学习，它能够培养我们敢担当、负责任的意识，也是体现我们中附主人翁意识的一种途径。

如果说以上只是我对升旗仪式讲话停留在思考阶段的看法，那么真正促使我今天在这里讲话的是一件不起眼的小事。去年6月份，初中毕业班的两位学长在中考结束后重返中附做升旗仪式讲话，不仅让我觉得新奇，也让我很疑惑：他们都毕业了，为什么还要回来做校会讲话呢？难道也是班主任布置任务？莫非他们要给我们这些学弟学妹们灌输一些刻苦学习，励志的故事？还是……正当我胡乱猜测之时，他们用平实的语言分享了三年的初中生活，抒发了对初中生活的留恋与回忆。我渐渐被他们的讲话所吸引。也许，他们只是想要再次表达自己对初中生活，对母校的怀恋。

这个学期开学，我猛然意识到自己的初中生活也已过半了，我想讲话的意愿也清晰而强烈了起来。或许，台下也有同学与我都有着相同的感觉吧：把做一次升旗仪式讲话当成了初中三年生活的目标之一。我们都是中附学子的一员，成长经历并不非凡，常常徘徊在两点一线之中。但在我们的成长中，一次校会讲话不容置疑将是我们在中附3年中留下的最亮眼的足迹。它不仅是锻炼，培养自己能力的机会，也是源于一种对母校的情怀。

我的讲话到此，谢谢！
