过去进行时表示在过去某一时刻或某一段时间内进行或发生的动作。
1. 过去进行时的基本用法主要表示过去某一时间点或者时间段正在进行的动作。 如:He was wrking the mment his father came他爸爸进来的时候他在工作。He was sleeping the whle night yesterday. 他昨晚一整晚都在睡觉。
2. 过去进行时表示现在主要是为了使语气委婉、客气。 如: I was wndering if yu culd 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。
3. 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, frever, cntinually等副词连用。 如: They were always quarrelling. 他们老是吵架。
just then(那时), at this time yesterday, yesterday afternn, at that time, the whle mrning, all day yesterday, frm nine t ten last evening, thse days,this mrning或以when, while,as引导的谓语动词是一般过去时的时间状语等。
过去进行时和一般过去时区别
1)过去进行时表示过去某时正在进行的动作,而一般过去时则表示一个完成的动作。也就是说用一般过去时,只表示有过这件事;用过去进行时,则强调动作的连续性。① I wrte a letter this mrning. 今天上午我写了一封信。(信写完了)I was writing a letter this mrning. 今天上午我在写一封信。(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 t me. 她朝我挥了挥手。 She was waving t me. 她一直朝我挥手。
when, while区别
他们作从属连词时都有“当……. 时候”之意,用法稍有不同:1.when引导的时间状语从句的谓语动词可以是短暂性动词,也可以是延续性动词,而while引导的时间状语从句中的谓语动词只能是延续性动词。
when +短/延while +延
以when, while及as引导的时间状语从句 延续性动词:指动作可以延续一段时间,而不是瞬间结束。 如:wrk、study、drink、eat等。非延续性动词:指动作极为短暂,瞬间结束如:start、begin、jump、knck等。
2.when引导的从句谓语动词如果是短暂性动词则用一般过去时,主句是延续性动词则用过去进行时,从句动作发生在主句动作的时间段之内(长动作用过去进行时,短动作用一般过去时);如果主句和从句两个谓语动词都是延续性动词则全部用过去进行时,这时when和while都可以用。
eg. ⑴ I was playing cmputer games when my father gt hme. (2) Mther was cking when/while I was ding my hmewrk.(3)She gt hme while/when her mther was cking .
3.when从句的谓语动词可以在主句谓语动作之前、之后或同时发生;while和as从句的谓语动作必须是和主句谓语动作同时发生。
He was abut t leave when he came acrss an ld friend.He had just left hme when a friend visited himHe was wrking when his friend came
While 有表对比的概念,译成 “然而”eg I was cleaning the flr while he was watching TV.
The children __________(play) ftball at fur yesterday afternn. The baby __________ (sleep) when the mther came back.
