过去进行时

　　 My brother fell while he was riding his bicycle and hurt himself.

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。
比较过去时与现在完成时

一般过去时的时间状语:
yesterday, last week，…ago, in1980, in October, just now, 具体的时间状语

　 3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know.
