【第3篇 小学五年级英语语法总结:be动词用法
be动词(am、is、are)+not、
情态动词can+ not、
助动词(do、does) + not
如何将一个肯定的陈述句改为否定句:
1、看句中有无be动词,如有,直接在be动词后+ not。
2、看句中有无情态动词,如有,直接在情态动词后+ not。
3、如上述二者都没有,就应用助动词+ not。分四个步骤:
(1)肯定陈述句中本来是没有助动词的,要加上去,位置在主语(某人或某物)后,动词前。
(2)确定助动词用do、does,根据句中动词,动词是原形的助动词就用do,动词是第三人称单数的助动词就用does,
(3)在助动词后加not。
(4)原句中动词假如发生变化就要恢复成原形。
强调一点,有some的要考虑是否要用any。
