其 它 用 法
1. 过去进行时表示现在主要是为了使语气委婉、客气。
如:
I was wondering if you could give me a lift.
我不知你能否让我搭一下车
【注】一般过去时也有类似用法,但比较而言,用过去进行时显得更客气,更不肯定。能否让我搭一下车。
2. 过去进行时表示感彩与现在进行时相似,过去进行时也可表示满意、称赞、惊讶、厌恶等感彩,也通常与 always, forever, continually等副词连用。
如: (1)、 They were always quarrelling. 他们老是吵架。
(2)、 My father was always smoking when he was young.
3. 动词be的过去进行时也可表示过去一时的表现或暂时的状态。
比较:
He was friendly.
他很友好。 (指过去长期如此)
He was being friendly.
他当时显得很友好。(指当时一时的表现)
S1: What were you doing while Li Jie was getting ready to go out
S2: I was sleeping while Li Jie was getting ready to go out.
S1: What were you doing while she was tavelling on the underground
S2: I ___________ while she was travelling on the underground.
While用法:表示在过去的某个时间,前后两个动作是同时进行的。
如果主要动作和背景动作都是延续的或同时发生的,那么主从句的动词都可用过去进行时
When和while用法: 描述一件事发生的背景;一个长动作发生的时候,另一个短动作发生。
My brother fell while he was riding his bicycle.
It was raining when they left the station.
短
短
长
长
过去进行时常与when, while连用,意思是
"当……之时"。
while后面一般跟延续性动词,常用进行时;
when后面既可跟延续性动词,也可跟瞬间动词,常用过去式。
一般过去时与过去进行时的区别
1、一般过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。
比较:
She wrote a letter to her friend last night.
她昨晚给朋友写了封信。 (信写完了)
She was writing a letter to her friend last night. 她昨晚一直在给朋友写信。 (信不一定写完)
2、一般过去时表示只做一次动作,而过去进行时却表示动作反复地进行。
如:
She waved to me.
她朝我挥了挥手。
She was waving to me.
她一直朝我挥手。
3、句中有a moment ago之类的短语一般用一般过去时。
4、句中有at this time last Sunday, from 8 to 9 yesterday 之类的状语一般用过去进行时。过去进行时可以用来代替一般过去时,表示更为偶然而非预定的动作:
I was talking to Tom the other day.
那天我跟汤姆聊天来着。
典型的例子
1) Mary ___ a dress when she cut her finger. A. made B. is making C. was making D. makes
答案C. 割伤手指是已发生的事情,应用过去时。同 时,when表时间的同时性,"玛丽在做衣服时"提供事情发生的背景,因此用过去进行时。
2) As she ___ the newspaper, Granny ___ asleep. read; was falling B. was reading; fell C. was reading; was falling D. read;fell
答案B.句中的as = when, while,意为"当……之时"。描述一件事发生的背景时,用过去进行;一个长动作发生的时候,另一个短动作发生。句意为 "在她看报纸时,奶奶睡着了。"句中的 fell (fall的过去时),是系动词,后跟形容词,如:fall sick。
