理由:
一、 概念和用法:过去进行时表示在过去某一时刻或某一段时间内进行或发生的动作.其形式为was /were + V-ing.常与表示过去的时间状语连用,如:last night,last Saturday等;或者与when,while,as引导的过去时间状语连用.例如:
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.
What was he researching all day last Sunday?上周日他一整天都在研究什么?
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:
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)
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)
四、 通常不能用于过去进行时的动词主要有:agree,be,believe,belong,care,forget,hate,have(拥有),hear,know,like,love,mean,mind,notice,own,remember,seem,suppose,understand,want,wish等.例如:
误:I was knowing the answer.
正:I knew the answer.我知道答案.
误:I wasn‘t understanding him.
正:I didn‘t understand him.我不明白他的意思.
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
