概念与结构
概念: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,即“过去的过去( past-in-the-past )”。
构成:“助动词 had + 过去分词”,其中 had 通用于各种人称。
They had already had breakfast before they arrived at the hotel.在到达旅馆之前,他们已经吃过了早饭。
She had finished writing the composition by 10:00 this morning. 今天早晨10点之前,她已经写完了作文。
- 二. 过去完成时的用法
用法1. 表示一个动作或状态在过去某一时间或动作之前已经完成或结束,即发生在“过去的过去”。
When I woke up, it had stopped raining.
用法2. 表示某一动作或状态在过去某时之前已经开始,一直延续到这一过去时间,而且动作尚未结束,仍然有继续下去的可能。
By the end of last year, he had worked in the factory for twenty years.
- 三. 过去完成时的判断依据
- 由时间状语来判定
一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有:
(1)by + 过去的时间点
I had finished reading the novel by nine o'clock last night.
(2)by the end of + 过去的时间点,
We had learned over two thousand English words by the end of last term.
(3)before + 过去的时间点,
They had planted six hundred trees before last Wednesday.
- 由“过去的过去”来判定
过去完成时表示“过去的过去”,是指在过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在:
(1)宾语从句中
当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。
She said that she had seen the film before.
(2)状语从句中
在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时。
When I got to the station, the train had already left.
注意: 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、从句都用一般过去时。例如:
Where did you study before you came here?
After he closed the door, he left the classroom.
(3)表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…",例如:
We had thought that you would come, but you didn't.
- 根据上、下文来判定
I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.

I didn’t know if he would come.
They never knew that population would become a big problem.
She didn’t tell me where she would go.
Betty said she would visit the Great Wall next Saturday.
- 二. 过去将来时的结构及用法

He told me he would go to Beijing.
2.“was/ were+going to+动词原形”常表示按计划或安排即将发生的事。
She said she was going to start off at once.
I was told that he was going to return home.
此结构还可表示根据某种迹象来看,很可能或即将发生的事情。

- come, go, leave, arrive, start等瞬时动词动词可用过去进行时表示过去将来的含义。
He said the train was leaving at six the next morning.
She told me she was coming to see me.
- 条件状语从句和时间状语从句中须用一般过去时代替过去将来时。
The teacher said that it would be very difficult to make progress if I didn’t work hard.
- 三. 过去将来时典型错误例析
- 我们不知道他是否要在会上发言。
误:We didn’t know whether he is going to speak at the meeting.
正:We didn’t know whether he was going to speak at the meeting.
析:该句主句为过去时,且宾语从句表示从过去某个时间看来将要发生的动作,所以从句要用过去将来时态。
- 老师问汤姆长大后准备干什么。
误:The teacher asked Tom what he was going to be when he would grow up.
正:The teacher asked Tom what he was going to be when he grew up.
析:在时间状语从句中,常用一般过去时表示在过去看来将要发生的动作。
- 他们说如果下星期天不下雨他们就去农场。
误:They said that they were going to the farm if it would not rain the next Sunday.
正:They said that they were going to the farm if it didn’t rain the next Sunday.
析:在条件状语从句中,也常用一般过去时表示在过去看来将要发生的动作。
- 王林打电话告诉她妈妈,她要买一些书。
误:Wang Lin rang up to tell her mother that she should buy some books.
正:Wang Lin rang up to tell her mother that she would buy some books.
析:过去将来时可以由“助动词should/would+动词原形”构成,但should一般只用于第一人称。而would可用于各种人称。
