知识点复习+习题跟踪训练
【知识复习】
过去进行时的概念和用法:
(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。
(2) 结构:was/were +doing (现在分词)
否定式:was / were not + doing
was not = wasn’t were not = weren’t
疑问句:将 was / were 调到主语前,结构为:Was/Were+主语+verb-ing?
回答:Yes, 主语+was/were.
No, 主语+ was not/wasn’t. were not/weren’t.
(三)用法
1. 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:
例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。
例2. It was raining when they left the station.他们离开车站的时候天正在下雨。
例3. 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。
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。
例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)
例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)
【知识梳理2】while\when\as 与过去进行时
1. when, while 和 as 这三个词都有“当………时候”的意思。
例1. There were fewer sandstorms when my grandparents were young. 我祖父母年轻时沙尘暴要少些。
例2. While Mille was watching TV, her mum was sleeping.米莉在看电视时,妈妈在睡觉。
例3. I saw a traffic accident as I was riding to school this morning.今天早晨我骑自行车时看到一起交通事故。
2. when 和 as 既可以指某一点时间,也可以指某一段时间,其从句谓语动词表示的动作既可以是瞬间性的,也可以是延续性的;while指一段时间,从句中的谓语动词必须是延续性的。
即:指一段时间时when, while 和as都可用;指一点时间时,只能用when或as,不能用while。
例. 试比较:
1. When/As he woke up, it was eight o’clock.(对)
2. While he woke up, it was eight o’clock.(错)
3. When/While/As I was waiting for a bus, I met her.(错)
3.当 while , when 和 as 放在句首时,两个句子应用逗号隔开。
例1. When the teacher came in, we were talking.
例2. While the pig was dancing, the rabbit was jumping.
例3. As the two men were leaving, a message arrived.
