过去完成时态
Explaining:
过去完成时的基本用法：
①表示在过去某一时刻或动作以前完成了的动作。可以用by，before等介词短语或时间状语从句来表示，也可通过上下文来暗示。
如：Had you reached the station before ten o’clock 你们十点以前已经到达火车站了吗？
I had finished writing my composition by 10:00 this morning.今天上午十点以前，我已经写完了我的作文。
②表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态，常和for，since构成的时间状语连用。
如：I had studied English for three years before coming to this school.
在我来这个学校之前，已经学习了三年英语。
③在主从复合句中叙述过去的事。动作发生在前，用过去完成时；发生在后，用一般过去时。
如：I returned the book that I had borrowed.
我归还了我借的书。
When I woke up , it had already stopped raining.
我醒来时雨已停了。
(2)by the time意为“到……时为止，在……以前”，引导时间状语从句，主句常用过去完成时。
如：By the time I came in, Tom had written his name on the blackboard.
当我进来时，汤姆已经把他的名字写在黑板上了。
By the time he had lost contact with the Party.
这时他已和党失去联系。

3. by the time+一般过去时 “在……以前”
4. when+一般过去时“在……之前”
