过去将来时
Past Future Tense
Amanda
【用法】        过去将来时表示在过去某个时间看来将要发生的动作或存在的状态。即:过去将来时是“立足过去,着眼未来”的一种时态, 常用于宾语从句中
判断这种时态的依据是:要有表示过去的“动作”,而不是时间。
I heard that they were going to return to
Shanghai soon. 
 我听说他们不久要回到上海。
【构成】①would/should + 动词原形
should主要用于主语是第一人称时;would可用于各种人称
He said he would go to the cinema tonight.
Mary told me she would go abroad next year.
I said I should learn French this year.
②was/were going to + 动词原形
No one knew when he was going e. 没有人知道他什么时候来。
She said she was going to start off at once.
她说她将立即出发。
I was told that he was going to return home.
有人告诉我他准备回家。
③ come, go, leave, arrive, start等动词可用过去进行时代替过去将来时。例如:
He said the train was leaving at six the next morning.
他说火车将于第二天早晨六点离开。
She told me she ing to see me.
她告诉我她要来看我。
④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。例如:
When she came I would let you know.
我不知道她什么时候来,但她来了我会告诉你。
The teacher said that it would be very difficult to make progress if I didn’t work hard.
老师说,如果我不努力学习的话,就很难取得进步。
过去将来时典型错误例析
1. 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。
2. 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。
3. 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。
4. 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。
