__________________________________________________________________________________ 理解并掌握过去进行时的用法

过去进行时

一、过去进行时的基本用法

过去进行时表示过去某一时刻或过去某一阶段内正在进行或一直进行的动作。

1. 表示过去某一时刻正在进行的动作。

I was doing my homework at this time yesterday. 昨天这个时候我在做作业。

2. 表示某一阶段内正在进行的动作。

I was staying here from March to May last year. 去年从3月到5月我一直呆在这。

二、过去进行时的构成：was/were + doing

否定句、一般疑问句、特殊疑问句

注意：英语中有四类动词一般不用进行时（不用现在进行时和过去进行时）

(1)表心理状态、情感的动词，如love, hate, like, care, respect, please, prefer, know等，若用进行时则

词意改变。I’m forgetting it . (=beginning to forget )

(2)表存在、状态的动词，如appear, exist, lie, remain, stand, seem等

(3)表感觉的动词，如see, hear, feel, smell, sound, taste等

(4)表一时性的动词，如accept, allow, admit, decide, end, refuse, permit, promise等。

三、时间状语标志词

at that time/moment, (at) this time yesterday (last night/Sunday/week…),

at+点钟+yesterday (last night / Sunday…), when sb. did sth

注意：

1. when后通常用短暂短性动词，while后通常用持续性动词，因此它所引导的状语从句中，谓语动词常用进行时态，例如：

When the car exploded I was walking past it. 我路过的时候那个车爆炸了。

While I was walking past the car it exploded. 当我路过的时候那个车爆炸了。

2. 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。例如：

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

3. 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。例如：

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。

四、一般过去时和过去进行时的区别

1. 一般过去式常表示在过去某时发生的动作或存在的状态（包括过去习惯动作），常与一般过去

时连用的时间状语有：

just now, a moment ago, yesterday, last week(month, year), the day before yesterday及表示过去的时间状语从句。例如：

I was sixteen yesterday old last year. 我去年16岁。

He worked in a factory in 1986. 他1986年在一家工厂工作。

I met her in the street the day before yesterday. 前天我在街上遇见了她。

He often swam in the river when he was young. 他小时候常在河里游泳。

2. 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。例如：

What were you doing at seven p.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。

3. 一般过去时往往表示某一动作已经完成，而过去进行时却表示动作在持续或未完成。例如：

I saw you while you were speaking to the teacher. 你在和老师谈话时我看见了你。

注意：有的过去时间状语既可用于一般过去时，也可用于过去进行时，但含义不同。例如：

She wrote a letter to her friend last night. 她昨晚给她的朋友写了封信。（信写完了）

She was writing a letter to her friend last night.她昨晚一直在给她的朋友写信。（信不一定写完）
