过去进行时

1、过去进行时的定义

肯定式 I was working He/She/it was working. 疑问式 Wereyou working? Washe/she/it working? Yes, he/she/it was. No, he/she/it wasn’t. 否定式 I was not working He/she/it was not working. We were not working You were not working They were not working We were working. Were we working? You were working Were you working? Theywere working Were they working? ４、过去进行时的基本用法

a. 过去进行时表示过去某一时间正在进行的动作，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 expecting you yesterday. 他们昨天一直在等待。 b. 过去进行时可与soon, the next moment, in minutes, minutes later等时间状语连用，表示一个新的动作刚刚开始。如：

Soon the whole town was talking about it. 不久镇上的人就都谈论起这种事了。

c. 过去进行时可用来申述原因或用作借口，这种用法常用在口语中。如： -- Have you finished your homework, Mary? 玛丽，你作业做完了吗？ -- No, I was helping my mother is the kitchen all day yesterday. 还没呢，我昨天一天都帮妈妈在厨房干活。

d. 过去进行时可用来为一个后一系列动作的发生提供背景。如： I hurt my leg when I was riding a bike. 我在骑车时把腿摔坏了。 e. 过去进行时可表示过去未曾实现的愿望或打算，这时be动词was/were要重读。如：

I was writing him a letter this morning and forgot all about it. 我本该今天早上给他写信的，后来全给忘了。

I was seeing her tomorrow. 我本来打算明天会见她。

He was watching the play yesterday, but he was too busy. 他昨天本来要看那场戏的，可是太忙了。

5、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。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。

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。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。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）
