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.,过去进行时表示感情色彩与现在进行时相似，过去进行时也可表示满意、称赞、惊讶、厌恶等感情色彩，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,Practice,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,rain,ing,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,。,用所给动词的正确形式填空：,Do you know what they _(do)this
