1、过去进行时：定义：过去进行时，是表示过去某个具体时刻正在进行的事情或动作。结构：主语+was/were +doing(动词的现在分词)+其他 用法：1、过去进行时表示过去某段时间内持续进行的动作或者事情。常用的时间状语this morning, the whole morning, all day yesterday, from nine to ten last 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 rese
2、arching all day last Sunday? 上周日他一整天都在研究什么?(3)My brother fell down 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 station. 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正
3、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)3. 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。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
4、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,constantly,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.他总是那样工作。6. 通常不能用于过去进行时的动词主要有： be, believe
5、, belong, care, forget, hate, have(拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。I was knowing the answer (x)I knew the answer. 正确I wasnt understanding him. (x)I didnt understand him. 正确We couldnt find you anywhere around 8 oclock yesterday ev
6、ening. -Im sorry for that. I _in the supermarket then. A:shop B:am shopping C:was shopping D:will shop 三、when, while 的用法 when和while与过去进行时有着密切的关系，他们作从属连词时都有“当.时候”之意，用法稍有不同：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
7、（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。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。when和while两个词还可以用作并列连词，但意思不同，when相当于“在那时”，等于at that time或just then;而while则相当于“而；却；但是”；相当于but,表示对比关系。（这一点暂时可以不掌握）eg. I was playing computer games when my father got home.
8、= When my father got home,I was playing computer games. (2) Mother was cooking when/while I was doing my homework. = When/While I was doing my homework, mother was cooking.例1.While she _ (watch) TV, her son _ (play) outside the room.2. Girls _(dance) while boys _(sing) at the party. 练习题When the teac
9、her _ (come) into the classroom, the students _（laugh）loudly.过去进行时跟一般过去时的区别：一：过去进行强调动作在过去某时或某段时间正在进行或持续，而一般过去时表示动作已经完成。 She was writing her composition last night. She wrote a composition last night. 二：表示状态，感觉或心里活动的静态动词（如be, like,love,hate,fear,own,hear,see,know,want,notice等）可用一般过去时，不能同过去进行时。My moth
