【第1篇 小学英语语法总结：过去完成时
1 、过去完成时是一个相对时态，表示过去的过去，只有在两个过去发生的动作相比较时才可显示出来。
e.g. as soon as we got to the station, the train had left.
注：主从句表达的动作紧接时，即两动作发生的时间没有明显时间上的悬殊或空档时，主从句都可用一般过去时。
e.g. where did your brother study before he joined the army?
2 、过去完成时可表示截止过去某一时间动作的总或动作的结束。
e.g. by the end of last month. we had reviewed four books
by eight o`clock, he had finished his homework.
与这个时态连用的时间状语常有：
by 1985, by eight o`clock, by then, by the end of last month, by the time when, when, as soon as, before 等连词引导的时间状语从句，表示主句动作结束的时间。
