限时练习：40min 完成时间： 月 日 天气： 作业10 过去进行时 【一】、过去进行时结构：was/were + 动词的现在分词 否定句则在was/were后加一个not,疑问句将was/were提前则可。 如：He was reading a book at 5:00pm yesterday. →He was not reading a book at 5:00 yesterday. →Was he reading a book at 5:00 yesterday? (Yes, he was./ No, he wasn’t.) →What was he doing at 5:00 yesterday? 【二】、过去进行时用法： （1）过去进行时主要表示过去某个时刻（时间点）正在进行的动作，常和过去的状语连用。 如：（just）then 那时，当时；at this/that time 在这/那时；at that moment=then在那时 at 3:00 yesterday afternoon在昨天下午三点；（at）this time yesterday在昨天这个时候 ①What were you doing at nine last night? 昨晚九点的时候，你在做什么？ ②I was watching TV at home at 3:00 yesterday afternoon. 我昨天下午三点正在家里看电视。 ③They were playing football at this time yesterday.昨天这个时候他们在踢足球。 （2）过去进行时也可以表示过去某一段时间内（时间段）正在进行的动作。常与those days, the whole morning, from 8:00 to 12:00 last night，last night 等时间状语连用。 ①From 1983 to 1998 , he was teaching at Yale . 从1983到1998年，他正在耶鲁大学教书。 ②They were building a bridge last winter . 去年冬天他们正在造一座桥。 ③He was writing a book those days. 那几天他正在写一本书。 （3）根据情境或上下文需要使用过去进行时。 A: I saw you in the library yesterday morning. What were you doing there? B: I was reading a book on Diaoyu Island. （4）过去进行时常出现在含有when和while引导的时间状语从句的复合句中. eg. ①I was playing computer games when my father got home. = When my father got home, I was playing computer games. ② Mother was cooking while I was doing my homework. = While I was doing my homework, mother was cooking. ★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： 结论 ※a. when后常跟短动词（瞬间动词），有时也可跟长动词。 while后只能接长动词（延续性动词或be动词）。 ※b. 主句和从句两个动作都发生在过去，长动作用过去进行时，短动作用一般过去时，短动作发生在长动作进行的过程当中。 ※C. while连接两个长动作，当两个动作一长一短时， while(when)放在长动词的前 面，when放在短动词的前面。 （5）过去进行时和一般过去时的区别。 过去进行时表示过去某时正在进行的动作，而一般过去时则表示一个完成的动作。也就是说用一般过去时，只表示有过这件事；用过去进行时，则强调动作的连续性。 ① I wrote a letter this morning. 今天上午我写了一封信。（信写完了） I was writing a letter this morning. 今天上午我在写一封信。（信不一定写完） ② Th
