10、ast evening, when, while例如： （1） We were watching TV from seven to nine last night. 昨天晚上七点到九点的时候我们在看电视。 （2） What was he researching all day last Sunday? 上周日他一整天都在研究什么？ （3）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。 （4） It was raining when they left the stat

11、ion. 他们离开车站的时候天正在下雨。 （5）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。 2. 过去进行时可以表示在过去某个时间点发生的事情。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) 3. 在复合句中

12、，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。例如： 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) 4、 表示在过去即将发生的动作。如： She asked him whether he was coming back for supper. 5、 表示过去的反复性或习惯性的动作，常与副词always,const

13、antly,continually,frequently等连用，常常带有说话人的某种感情色彩。如： His mother was always working like that.他目前总是那样工作。 6. 通常不能用于过去进行时的动词主要有：agree, be, believe, belong, care, forget, hate, have(拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。例如：误：I was knowing the

14、 answer. 正：I knew the answer. 我知道答案。 误：I wasnt understanding him. 正：I didnt understand him. 我不明白他的意思。 典型例题： 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 _ as

15、leep. A. read; was falling B. was reading; fell C. was reading; was falling D. read;fell 3) 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。（四） 过去进行时和一般过去时的区别 1 一般过去时叙述旧事，过去进行时描述背景。 、一般过去时 ） 叙述过去状态、动作或事件 He went to Beiji

16、ng the other day.（带具体时间） ） 表示过去的习惯 a) would ,used to与过去时 would 表间断性不规则的习惯，常带频率时间 used to 表一贯性有规律的习惯 They used to meet and would sometimes exchange one or two words. He smoked a lot two years ago. （过去行为） b) Would 用于文中不用于句首，只表过去习惯。 Used to 表今昔对比的含义，叙述习惯动作可与would 换用。 When he was a boy , he would often

17、go there . （叙述过去） She isnt what she used to be. (今昔对比) c) 表示状态时一般只用used to Tom used to be fat /There used to stand a tree there. (状态) d) was (were) used to +ving表示“合适于，适应于.” He used to work at night . (“习惯”表经常) He was used to working at night. (习惯表适应) ） 表示过去的经历，平行动作，依此事件用一般过去时。Hesatthereandlistenedt

18、otheradio.(依此发生)） 表示客气委婉的语气，用于情态动词，助动词和want , wonder , hope 等 How did you like the film? / Could you help me? B. 过去进行时 表示在过去某阶段或某一时刻正在发生 What were you doing at 8:30 last night? (过去某时刻正在发生) 短暂性动词用过去进行时表示按计划、打算 During that time he was going with us.(表示打算) 与always ,often ,usually 等连用表喜爱，讨厌等感情色彩。 He was

19、 always Changing his mind. 2、 过去进行时与一般过去时的区别 （1） 过去进行时与一般过去时，两者都表示过去发生的动作,但过去进行时表示在过去某一特定的时间点或时间段正在进行的动作,而一般过去时表示在过去时间完成的动作例如: I was typing a letter last night. 昨晚我在打一封信(可能没打完) I typed some letters last night. 我昨晚打了一些信(已经打完) A. 过去进行时却表示动作在持续或未完成，而一般过时往往表示某一动作已经完成。 I was reading the book at that time

20、. (未读完，“读”的片段) I read the book yesterday. (已读完，表整个“读”) B、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。 She waved to me. 她朝我挥了挥手。 It was raining all night.(优先用was raining ,rained 为持续动词，故也可使用) He was writing a letter the whole of afternoon. (短暂动词与持续时间连用，表反复，连续发生，不可用一般过去时)when 和while的用法区别 两者的区别如下： when是at or during

21、the time that, 既指时间点，也可指一段时间； while是during the time that，只指一段时间，因此when引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词，而while从句中的动词必须是延续性动词。 when 说明从句的动作和主句的动作可以是同时，也可以是先后发生；while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。 由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导，如：a. When the teacher came in,

22、we were talking. 当此句改变主从句的位置时，则为：While we were talking, the teacher came in. They were singing while we were dancing.1. I _(have) my breakfast at half past six yesterday morning. 2.
