We were watching TV from seven to nine last night. 昨晚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？
二、 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? 昨晚九点她在做什么？ (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)
三、 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)
四、 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。
五、常用的时间状语
this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while如：
　　 My brother fell while he was riding his bicycle and hurt himself.　
　　 It was raining when they left the station.
　　 When I got to the top of the mountain, the sun was shining.　
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.
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。
