II根据如下的语言现象总结关于一般过去进行式的语言规律 我妈妈在做饭，同时，我爸爸在看报纸。 My mother was cooking while my father was reading a newspaper. 过去进行时和 When 连用 A was/were +doing sth When B +did sth. 过去进行时和 while 连用 A was/were +doing sth While B + was/were +doing sth at 9 p.m. yesterday A rabbit was ……. While a pig was…. 总结 when while 用作连词，都是“当...时”的意思 when引导的时间状语从句，通常使用一般过去时 while引导的时间状语从句，通常使用（过去）进行时 while前后的动词都是进行时态时，while表示与此同时。 一般过去时与过去进行时的区别 1、一般过去时往往表示某一动作已经成，而过去进行时却表示动作在持续或未完成。 　比较： She wrote a letter to her friend last night. 她昨晚给朋友写了封信。 (信写完了) She was writing a letter to her friend last night. 她昨晚一直在给朋友写信。 (信不一定写完) 2、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。 如： She waved to me. 她朝我挥了挥手。 She was waving to me. 她一直朝我挥手。 3、句中有a moment ago之类的短语一般用一般过去时。 4、句中有at this time last Sunday, from 8 to 9 yesterday 之类的状语一般用过去进行时。过去进行时可以用来代替一般过去时，表示更为偶然而非预定的动作： I was talking to Tom the other day． 那天我跟汤姆聊天来着。 典型的例子 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. 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。 1.
