初中英语过去进行时讲解及练习
　　(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：
（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）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 o'clock 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、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 answer. 　　正：I knew the answer. 我知道答案。
　误：I wasn't understanding him. 　　　正：I didn't 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。
　　（四）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. (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)
