过去进行时讲解与练习过去进行时讲解与练习1、知识、知识 1：(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。 What was he researching all day last Sunday?上周日他一整天都在研究什么？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。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，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. 不用于进行时的动词感官动词：hear,see,notice,feel,taste 表示态度感情的动词： like,love,hate 表心理状态： feel,want,prefer 表占有：own,have, 表存在状态和持续： look,owe,be 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 falling B. was reading; fell C. was reading; was falling D. 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。2.2.例题解析例题解析一、单项选择1.

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. 2. They were singing while we were dancing.四、课堂练习四、课堂练习一、选择题。 （ ）1.
