过去进行时-英语语法讲解与练习.ppt

过去进行时,基本概念：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。,基本结构：主语+was/were+doing+其他内容,用法,一、过去某个时间点正在发生的事情 时间点可以用介词短语、副词或从句来表示 如： What was she doing at nine oclock yesterday? 昨天晚上九点她在做什么？（介词短语表示时间点） When I saw him he was decorating his room. 当我看见他的时候他正在装饰房间。（when从句表示时间点）,二、过去一段时间内一直在进行的动作 常用的时间状语：this morning,the whole morning,all day yesterday,from nine to ten last evening. 如： We were watching TV from seven to nine last night. 昨天晚上七点到九点的时候我们正在看电视。 What was he researching all day last Sunday? 上周日他一整天都在研究什么？,三、过去进行时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。 常用when，while引导的从句 如： My brother fell while he was riding his bicycle and hurt himself. 我哥哥骑自行车的时候从车上摔下来，受伤了。 It was raining when they left the station. 他们离开车站的时候天正在下雨。 When I got to the top of the mountain,the sun was shining. 当我到达山顶的时候，阳光灿烂。,四、在复合句中，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。 如： While he was waiting for the bus,he was reading a newspaper. 他边等车边看报。（两个动作都是延续的） He was cleaning his car while I was cooking. 他擦车时我在做饭。（两个动作同时进行）,五、用过去进行时代替过去将来时 1）表示渐变的动词有：get,grow,become,turn, run,go,begin,die等 如：The leaves were turning red. It was getting warmer and warmer. He was dying. 2)短暂性动词用于过去进行时表示即将发生的或预定中计划好的活动。 如：We were leaving soon. During that time he was going with us.(表示打算）,六、一般过去时代替过去进行时 句型：There went/came+n. 如： There went the bell. There came the crying of Mrs Smith.,七、与always,often,usually等连用表喜爱，讨厌等感情色彩。 如： He was always changing his mind.,-Did you watch the basketball match yesterday? -Yes,I did.You know,my brother_in the match. A.is playing B.was playing C.has played D.had played,B,解析 句意为：-你昨天看篮球赛了吗？-看了。你要知道，我的弟弟在那场比赛中上场打球。故此处应该用过去进行时态。,The telephone_,but by the time I got indoors,it stopped. A.had rung B.was ringing C.rings D.has rung,B,解析 由句意“电话响着，但我进入室内时停了。”可知，该题表达的时间与过去有关，而与现在无关。由此，排除C、D两项。而如果选A项，则与后面it stopped在逻辑上存在错误。,-Tom,you didnt come to the party last night? -I_,but I suddenly remembered I had homework to do. A.had to B.didnt C.was going to D.wouldnt,C,解析 have to不得不，be going to do sth.表示按计划或安排要做某事。根据but可知，此处应选择C项。,-Did you see a man in black pass by just now? -No,sir.I_a newspaper. A.
