初中过去进行时讲解练习及答案`

过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作，常和表过去的时间状语连用，如： I was doing my homework at this timeyesterday.昨天的这个时候我正在做作业。

They were waiting for youyesterday.他们昨天一直在等你。

过去进行时的构成：肯定形式：主语was/wereV-ing 否定形式：主语was not wasnt/were not werentV-ing疑问形式：Was/Were主语V-ing。

基本用法：1.过去进行时表示过去某一段时间或某一时刻正在进行的动作。

常与之连用的时间状语有， that attime/moment at this time yesterday lastnight/Sunday/week… at 点钟 yesterday last night /Sunday…，when sb. did sth等时间状语从句，如： What were you doing at 7p.m. yesterday昨天晚上七点你在干什么？ I first met Mary three years ago. She was working at a radio shop at the time.我第一次遇到玛丽是在三年前，当时她在一家无线电商店工作。

I was cooking when she knocked at the door. 她敲门时我正在做饭。

2. when后通常用表示暂短性动词，while后通常用表示持续性动词，因此它所引导的状语从句中，谓语动词常用进行时态，如： When the car exploded I was walking past it. While I was walking past the car it exploded. 3.when用作并列连词时，主句常用进行时态，从句则用一般过去时，表示主句动作发生的过程中，另一个意想不到的动作发生了。

如： I was walking in the street when someone called me. 我正在街上走时突然有人喊我。

4. when作并列连词，表示“（这时）突然”之意时，第一个并列分句用过去进行时，when引导的并列分句用一般过去时。

如： I was taking a walk when I met him.我正在散步，突然遇见了他。

We were playing outside when it began to rain.我们正在外边玩，这时下起雨来了一般过去时与过去进行时的用法比较：一般过去时表示“在过去某个时间发生的动作或存在的状态”，而过去进行时则表示“在过去某个特定时间正在进行的动作”。

如：Tom wrote a letter to his friend last night. 汤姆昨晚给他的朋友写了封信。

（信写完了） Tom was writing a letter to his friend last night.汤姆昨晚一直在给他的朋友写信。

（信不一定写完，只是强调了动作的延续性）。

过去进行时和一般过去时的差别：一般过去时表示“在过去某个时间发生的动作或存在的状态”，而过去进行时则表示“在过去某个特定时间正在进行的动作”。

例如： I was reading an English novel last night. 昨晚我在看一本英文小说。

（可能没看完） I read an English novel last night我昨晚看了一本英文小说。
