过去进行时

(一)定义

过去进行时,是表示过去某个具体时刻正在进行的事情或动作。

(二)结构

was/were +doing (现在分词)

(三)用法

1、过去进行时表示过去某段时间内持续进行的动作或者事情。常用的时间状语this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while等等

(1)We were watching TV from seven to nine last night.

2. 过去进行时可以表示在过去某个时间点发生的事情。时间点可以用介词短语、副词或从句来表示。

What was she doing at nine o'clock yesterday?

昨天晚上九点她在做什么?第一文库网 (介词短语表示时间点)

When I saw him he was decorating his room.

当我看见他的时候他正在装饰房间。 (when从句表示时间点)

3. 在复合句中,如果主要动作和背景动作都是延续的或同时发生的,那么主从句的动词都可用过去进行时。

While he was waiting for the bus, he was reading a newspaper.

他边等车边看报。 (两个动作都是延续的)

He was cleaning his car while I was cooking.

他擦车时我在做饭。(两个动作同时进行)

4、表示在过去即将发生的动作。

She asked him whether he was coming back for supper.

5、表示过去的反复性或习惯性的动作,常与副词always, constantly, continually, frequently等连用,常常带有说话人的某种感情色彩。

His mother was always working like that.

(四)句型

肯定句: 主语+was/ were+ doing+…

He was cooking at six last night.

否定句: 主语+was/ were +not(wasn’t/ weren’t) +doing+…..

He was not cooking at six last night.

一般疑问句: Was/Were +主语+ doing+….?

两回答 肯:Yes, 主语+was/were 否:No,主语+wasn’t/ weren’t Was he cooking at six last night?

Yes ,he was No, he wasn’t.

特殊疑问句: 特殊疑问词+一般疑问句

What was he doing at six last night?

when 和while的用法区别:

① when既指时间点,也可指一段时间,while只指一段时间,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词。

② when 说明从句的动作和主句的动作可以是同时,也可以是先后发生;while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。 ③ 由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时;如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导

When the teacher came in, we were talking.

当此句改变主从句的位置时,则为:

While we were talking, the teacher came in.
