（1）过去完成时态的用法
过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作或状态，它描述的动作发生在“过去的过去”。基本结构为“主语+助动词had+过去分词”。否定式为“had not (hadn’t) +过去分词”；疑问句中把 had放到主语前面。Language points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。Language points②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。Language points③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。Language points(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。
