初中英语过去进行时专项语法讲解(一)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。(二)结构 was/were +doing (现在分词)(三)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: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. 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: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. 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 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 _ asleep.A. read; was fallingB. was reading; fellC. was reading; was fallingD. 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。过去进行时与一般过去时区别都强调过去发生的事 进行时强调过程,不一定完成 过去时强调事件,一定完成 p,s表示一个动作正在进行时,另一个动作发生了 如:He played when I was studying. 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) when 和while的用法区别 两者的区别如下: when是at or during 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, 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. b They were singing while we were dancing. 一、 选择题。1.
