8.过去完成时 表示动作发生在过去某一时间之前已经完成的动作或状态， 强调“过去的过去”， 常与 by the time, by the end of…,before , by 等引导时间的状语连用。
基本结构 主语+ had + 动词过去分词 + 其他成分 When I got to the cinema yesterday the film had begun already. He had learned English before he came here.
现在完成时与一般过去时的区别： 1)现在完成时侧重于对现在的影响；而一般过去时侧重于某一动作发生在过去某个时间或某段时间。即现在完成时侧重于现在的结果，而一般过去时侧重于动作发生的时间。例如：
I have seen the film. 我看过这部电影。(现在我仍记得电影的内容) I saw the film three days ago. 三天前我看了这部电影。(强调是三天前,而不是别的什么时候看的电影)
be going to含有“打算，准备”的意思，而will则没有这个意思， She is going to lend us her book. He will be here in half an hour.
be about to＋V.原形（意为马上做某事，在时间上指最近的将来） I am about to leave school. 不能与表示时间的副词连用。 They are about to set out.(√) They are about to set，变y为i加-ed. study----studied carry----carried cry----cried try----tried d)以元音字母＋y结尾的单词直接加-ed. play----played stay----stayed
