①.when"当......时候"引导的时间状语从句，其动词既可以是延续性动作的动词，也可以是瞬间性动作的动词,如：

_________ the students heard the teacher's footsteps, they all stopped talking.

当学生们听到老师的脚步声时，他们都停止了讲话。(从句动作发生在前)

② as"当.......时候"或"一边.......一边"引导的时间状语从句其动词的动作是延续性的，而且侧重表示主句和从句的动作并相发生：

We were having breakfast __________ she was combing her hair.

她梳头时我们在吃早饭。

③ while表示"在某一段时间里"或"在……期间"，其所引导的从句的动作是延续性的，并侧重表示和主句的动作同时发生。如：

大学毕业后我们就再没见过面。
