[自我归纳]
过去完成时表示过去某一时间或动作以前已经发生或完成了的动作,对过去的某一点造成的某种影响或是结果,用来指在另一个过去行动之前就已经完成了的事件。其中1,2,3,5,6的谓语动词的动作发生在另一动词的动作之前。4句中用的是by the time...(到……之前/为止)结构。
一、过去完成时的结构
主语+had+动词过去分词+其他.
①肯定句:主语+had+动词过去分词+其他.
②否定句:主语+had+not+动词过去分词+其他.
③疑问句:Had+主语+动词过去分词+其他?
肯定回答:Yes,主语+had.
否定回答:No,主语+hadn't.
④特殊疑问句:特殊疑问词或词组+had+主语+动词过去分词+其他?
⑤被动语态:主语+had(not)+been+动词过去分词+其他.
二、过去完成时的用法
1.过去某一时刻或动作之前已完成的动作或存在的状态。可以用by,before等介词短语或一个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,还可通过上下文来表示。
When the explorer hurried to the destination,the others had already left.
当这名探险者匆忙赶到目的地的时候,其他人已经离开了。
By ten o'clock last Sunday,I had taken 200 pictures on the mountain.
到上周日10点钟,我已经在山上拍摄了200张照片。
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。
He told us that he had done the scientific research for 5 years.
他告诉我们他做科学研究已经5年了。
3.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。
I had never thought that you were content to help me.
我从未想过你愿意帮我。
I had intended to come over to see you, but was prevented from doing so.
我原打算过来看你,但受阻未成。
4.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。
She said that she had never been to Paris.
她说她从未去过巴黎。
5.在状语从句中,在过去不同时间发生的两个动作中,发生在前的,用过去完成时;发生在后的,用一般过去时。从句常由when,before,after,as soon as,till/until引导。
When I got to the railway station, the train had left.
当我到达火车站时,火车已经开走了。
[名师点津] before,after引导的时间状语从句中,由于before和after本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句多用一般过去时。
After he arrived in England,he worked hard to improve his English.
到达英格兰之后,他努力提高自己的英语水平。
6.过去完成时的常用固定句型
(1)主语+had hardly/scarcely+过去分词+when+从句(从句用一般过去时)/主语+no sooner过去分词+than+从句;当hardly,scarcely,no sooner等表示否定意义的词(组)位于句首时,主句要倒装。
I had no sooner reached home than it began to rain.
=No sooner had I reached home than it began to rain.
我刚到家就下雨了。
(2)It was+一段时间+since从句(从句用过去完成时)
It was at least three months since I had left Beijing.
我离开北京至少有3个月了。
(3)It was the first/second/...time+(that)从句(从句用过去完成时)

那是我第一次用英语在网上聊天。
(4)主句(过去完成时)+by the time ...(一般过去时)
We had got everything ready by the time they arrived.
在他们到达时,我们已经做好一切准备了。
(5)句子(过去完成时)+by the end of ...(表示过去的时间)
By the end of last term,we had learned English at least for four years.
到上个学期末,我们至少已经学了四年英语了。
7.过去完成时和一般过去时的区别
(1)一般过去时表示过去发生的动作或存在的状态,而过去完成时则表示在过去某一时间或动作之前已经完成的动作或状态,即“过去的过去”。当强调过去某一动作发生在另一动作之前时,常用过去完成时。
We had reached the station before ten o'clock.
10点钟之前我们已到达了车站。
(2)过去完成时与一般过去时都可以和确定的、表示过去的时间状语连用,但意义有所不同。
He had done the work at six o'clock.
在6点钟的时候他已经完成了那项工作。
He did the work at six o'clock.
他是在6点钟的时候做那项工作的。
8.过去完成时和过去完成进行时的区别
过去完成进行时强调动作的持续性,过去完成时表示在过去某一具体时间或动作之前已经发生或完成的动作,强调动作已结束这一事实。
They had been building the road by the end of last month.
到上个月月底为止,他们一直在修建这条路。
They had built the road by the end of last month.
上个月月底,他们已建好了这条路。
