一、基本结构与用法

表示两个同时进行的动作

当主句和从句的动作在过去某一时间段内同时发生时,使用"while"引导时间状语从句,从句用过去进行时,主句用过去完成时或一般过去时。

- 例:

- While I was reading a book, my brother came in. (我正在读书时,他进来了)

强调动作的持续性

该结构要求从句和主句的动作必须是延续性的(如"reading"、"cooking"),而非瞬间动作(如"opened"、"stopped")。

二、典型例句解析

日常场景

- While she was listening to music, the phone rang. (她正在听音乐时,电话响了)

- While we were having dinner, he came into our room. (我们正在吃晚饭时,他进了房间)

自然现象与行为结合

- While it was raining, we watched a movie. (下雨时,我们看了电影)

- While the storm passed, the power came back. (暴风雨过后,电力恢复了)

对比与转折

- While she was studying hard, her cat jumped on her desk. (她正在努力学习时,猫跳上了书桌)

- While we were planning the trip, unexpected delays occurred. (我们正在计划旅行时,意外延误发生了)

三、注意事项

时间范围:

需明确两个动作是否在同一时间段内完成,避免混淆。

动词选择:仅限延续性动词(如"eating"、"reading"),非延续性动词需改写为延续性表达(如"have dinner"改为"were having dinner")。

通过以上例句和解析,可灵活运用"while+过去进行时"结构描述过去同时发生的动作。
