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)

五、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。
