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等介词短语或一个时间状语从句(在复合句中,由时间连接词引导的状语从句叫做时间状语从句)来表示,也可以用一个表示过去的动作来表示,还可能通过上下文来表示.
例；By nine o’clock last night,we had got 200 pictures from the spaceship.
到昨天晚上9点钟,我们已经收到200 张飞船发来的图片.
（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.
例；I had been at the bus stop for 20 minutes when a bus finally came.
我在车站已经等了20分钟,一辆公共汽车终于来了.
He said he had worked in that factory since 1949.
他说他自从1949年以来他就在那家工厂工作.
（3）叙述过去发生的事情,在已叙述了过去发生的事情后,反过来追述或补充以前发生的动作时,常使用过去完成时.
例；Mr.Smith died yesterday.He had been a good friend of mine.
史密斯先生昨天就去世了.他以前是我的好朋友.
I didn’t know a thing about the verbs,for I had not studied my lesson.
我对动词一无所知,因为我没有好好学习功课.
（4）在含有定语从句的主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时.
例；I returned the book that I had borrowed.我已归还了我借的书.
She found the key that she had lost.她发现她失去了的钥匙.
（5）过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句（或间接引语）中,这时从句中的动作发生在主句表示的过去的动作之前.
例；He said that he had known her well.他说他早就很了解她了.
I thought I had sent the letter a week before.我认为我一星期前就把信寄出去了.
（6）状语从句：在过去不同时间发生的两个动作中,“发生在过去的过去”,用过去完成时；发生在后,用一般过去时.
如when,before,after,as soon as,till/until引导的
e.g：When I woke up,it had already stopped raining.
我醒来时雨已停了.
She didn’t go to bed until she had finished her work.
她直到把工作做完之后才睡觉.
注意：如果两个动作紧接着发生,则常常不用过去完成时,特别是在包含before和after的复合句中,因为 这 时从句的动作和主句的动作发生的先后顺序已经非常明确,这时可以用一般过去时代替过去完成时.
e.g：After he 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.
（7）动词think,want,hope,mean,plan,intend等用过去完成时来表示过去未曾实现的想法,希望,打算或意图等.
e.g：They had wanted to help but could not get there in time.
他们本来打算去帮忙,但没有及时赶到那里.
We had hoped to be able to come and see you .
我们本来希望能来看看你.
（8）过去完成时还可用在hardlywhen no soonerthan It was the first
time…等固定句型中.
e.g：Hardly had he begun to speak when the audience interrupted him.
他刚开始演讲,听众就打断了他.
No sooner had he arrived than he went away again.
他刚到就又走了.
It was the third time that he had been out of work that year.
这是他那一年第三次失业了.
时间状语
before,when,after,by+,until,once,had no sooner……than,yet,already等.
再问： 对不起我说的是had the car checked 和 had checked the car ,在这个句子上有什么区别，我可以写成 I havn't had checked the car for february.
再答： have在这个搭配里是使役动词 意为使...让... have sth done 就是使某物成一种...的状态 比如 have my bicycle repaired 意思是使我的自行车被修理 其实就是说修我的自行车 这个结构强调的是sth是被动的接受动作,而不是主动,并且可以不标明动作的施行者,只强调接受动作的一方. 拿上面的例子来说 修车可能并不是你自己修 但是你要去把它送修 那么这个时候就可以使用这个结构 不用说明是"修车的人"修了你的车. 过去式就是had sth done
例；By nine o’clock last night,we had got 200 pictures from the spaceship.
到昨天晚上9点钟,我们已经收到200 张飞船发来的图片.
（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.
