【语法感悟】
过去完成时是由______________构成的;其否定形式是________________;其被动语态是________________。
had +过去分词
hadn't/had not done
had been done
语法精讲
一、定义
过去完成时的动作需在过去某一时间之前发生,即发生在“过去的过去”。
When they got there,the ship had set off.
当他们到达那时,轮船已经起航了。
二、过去完成时的构成
肯定句:主语+had done
否定句:主语+had not done
被动句:主语+had (not) been done
一般疑问句:Had+主语+done
特殊疑问句:疑问词+had+主语+done
Soon I realized I had made a serious mistake.
我很快就意识到我犯了一个严重的错误。

Had Tom left before I arrived
我到达之前汤姆就离开了吗
What had you done before I arrived here
我来这儿之前,你们做了什么
三、过去完成时的用法
1.“已完成”的用法:
表示某一动作或状态在过去某一时间之前或过去某一动作之前已经完成。句中常用by引导的时间状语或以before,until,when,than等词引导的内含一般过去时的时间状语从句。
By 5:00 yesterday morning we had done the work.
到昨天早上5点钟时,我们已经做完了那件工作。
He had just finished sweeping the classroom when the teacher returned from the office.
老师从办公室回来时,他刚把教室扫完。
【特别提醒】
在包含before和after的复合句中,因为从句动作和主句动作发生的先后顺序已经非常明确,可以用一般过去时代替过去完成时。
The train (had) started before I reached the station.
在我到达车站之前,列车已经开了。
After he (had) arrived in England,Marx worked hard to improve his English.
马克思到达英格兰之后,努力提高他的英语水平。

直到那时一切都很顺利。
John and Jane had known each other for a long time before their marriage.
约翰和简在结婚前就认识很长时间了。
3.“虚拟性”的用法:
过去完成时有时表示一种未实现的愿望或想法,常用动词有hope,expect,suppose,think,want,intend,mean,plan等;或用在if,wish,as if引导的虚拟语气中。
He had intended to help you but he had no time then.
他本打算帮助你的,但当时没有时间。
If she had worked hard,she would have succeeded.
要是她努力的话,她就会成功了。(事实上她没努力,也没成功。)
I wish I had gone with you to the concert.
我要是和你一起去音乐会就好了。
4.用于某些固定句型中:
①在hardly/scarcely/barely...when...,no sooner...than...等结构中,表示“刚刚……就……”。when和than从句里用一般过去时,主句用过去完成时,当否定副词位于句首时,要用部分倒装,即:
Hardly/Scarcely+had+主语+done+when+过去时
No sooner+had+主语+done+than+过去时
I had hardly/no sooner got home when/than the rain poured down.
=Hardly/No sooner had I got home when/than the rain poured down.
我刚到家,大雨就倾盆而下。
②It was/had been+一段时间+since从句。since 从句的谓语用过去完成时。
It was ten years since we had had such a wonderful time.
