过去进行时的讲与练(与一般过去时)

过去进行时的讲与练

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 time yesterday.昨天的这个时候我正在做作业。

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

过去进行时的构成：

肯定形式：主语+was/were+V-ing

否定形式：主语+was not (wasn't)/were not (weren't)+V-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，at that time/moment, (at) this time yesterday (last night/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。（已经看完）
