3、 重要语法归纳
(一)过去完成时
含义:表示过去某一时间或动作之前发生或完成的动作
结构:助动词had+动词过去分词
标志语:1)by+过去的时间
2) by the end of+过去的时间点
3) By the time+从句
4) Before/when+时间点
(二)比较一般过去时和现在完成时的异同
1. 共同点:动作都是在过去完成。
I saw the film yesterday evening.
I have seen the film before.
(看电影这件事都是在过去完成的。)
2. 区别:
①现在完成时强调过去发生的动作对现在的影响和结果,而一般过去时与现在没有联系,只是说明某个动作发生的时间是在过去。
②一般过去时通常与具体明确的过去时间状语连用。如yesterday, last week , two years ago,just now,in 2002 等;而现在完成时则常与 just ,already ,ever ,never 等模糊的过去时间状语和 these days ,this week ,since..., for... 等表示一段时间的状语连用。
