过去进行时的四种用法如下:
1.表示过去某个时刻或某一阶段正在进行的动作
常和表示过去时间的状语如then(那时),at this(that)time(在这时/那时),yesterday(昨天),last year(去年)等连用。但在不少情况下,没有表示时间的状语,此时需通过上下文来表示:
What were you doing at about 4 o'clock yesterday afternoon? —I was listening to music.昨天下午4点钟左右你在做什么? ——我在听音乐。
Jane was working on her homework last night.简昨晚在写作业。
2.在某事(动作)发生前开始的动作
过去进行时和一般过去时经常在一个句子里使用。用过去进行时表示过去正在进行的动作。过去进行时可用于主句,亦可用于从句:
Just as I was leaving the house,the telephone rang.我正要出门,电话铃响了。(用于从句)
He broke his leg when he was playing football.他踢足球的时候把腿伤了。(用于从句)
She was reading when he called.他来访时,她正在看书。(用于主句)
3.表示同时进行的动作
While you were writing letters,I was reading a book.你写信的时候,我在看书。
While we were having breakfast,John was talking on the tele-phone.我们吃早饭的时候,约翰在打电话。
4.表示过去将来的动作
过去进行时亦可表示从过去某时间看将要发生的动作。常用在间接引语中:
She was leaving early the next morning.第二天一早她就要离开此地了。(从过去某时间看)
She asked whether he was coming back for lunch.她问他晚饭是否回家来吃。(用于间接引语中)
We were coming to see you,but it rained(so we didn't).我们本预备来看你,只是下雨了。
