Information Technology PPT，第五部分内容：语法整体突破

过去将来时

一、基本构成

过去将来时表示从过去某个时间看将要发生的动作或存在的状态，常用于宾语从句或间接引语中。过去将来时常用“should/would＋动词原形”或“was/were going to＋动词原形”来表达。

[合作探究]　画出下列句子中的过去将来时

示例：I asked if he would come and fix my TV set.

①He asked me yesterday when I should leave for Paris.

②They wanted to know how they would finish the homework earlier.

③I wish I would go with him to the cinema tonight.

④I was told that he was going to return home.

⑤He said that he would wait for me at the school gate.

[自主发现1]

过去将来时是由“____________________________”或“____________________________”构成的。

过去将来时的基本特征，即“立足过去，着眼未来”。它表示从过去某一时间来看将要发生的某个动作或存在的某种状态。但这个“将来”时间绝不会延伸到“现在”，而仅限于“过去时间区域内”。

[合作探究]　

He said that he would wait for us at the bus stop.他说他要在车站等我们的。

Whenever we had trouble, he would come to help us.

每当我们遇到困难时，他总会给予帮助。

I didn’t know when she would come，but 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。

We were going to go to the cinema when the phone rang.

我们正准备去电影院，这时电话响了。

[自主发现2]

(1)过去将来时可以表示从过去某时看来将要发生的动作或存在的状态。

(2)条件状语从句和时间状语从句中须用________________代替过去将来时。

(3)was/were going to do表示____________、计划做某事，或将要发生某事。

[名师提醒]　表示过去的某种习惯性行为，只用____________。

三、其他结构

[合作探究]

我不能参加汤姆的生日晚会，因为我要去医院。

He was on the point of leaving when we came in.

我们进来时，他正要动身。
