过去进行时的用法与练习

一、用法说明

■表示在过去某一时刻或某一阶段正在发生的动作。如:

What were you doing this time yesterday? 昨天这个时候你在做什么?

句型:

肯定句:主语+was/were+doing+其它

否定句:主语+was/were+not+doing+其它

一般疑问句及答语:Was/Were+主语+doing+其它

特殊疑问句:特殊疑问词+was/were+主语+doing+其它

注意:

一、过去进行时的主要用法是描述一件事发生的背景;一个长动作发生的时候,另一个短动作发生。常用的时间状语this morning,the whole morning,all day yesterday,from nine to ten last evening,when,while。例如:

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

昨天晚上七点到九点的时候我们在看电视。

4.It was raining when they left the station. 他们离开车站的时候天正在下雨。

5.When I got to the top of the mountain, the sun was shining.

当我到达山顶的时候,阳光灿烂。

二、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。如:1.What was she doing at nine o'clock yesterday? 昨天晚上九点她在做什么?(介词短语表示时间点) 2.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)

三、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。例如: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)
