还可以表示，表示主句动作发生在从句动作进行的过程中。

例：While his mother (cook) in the kitchen, the boy fell asleep in the chair.
5.在when 和while引导的从句中，当主句和从句的主语一致，并且从句中有be动词时，可以省略主语和be 动词，构成when/ while + 结构。

例：1）她遇到困难时总是向我求助。

, she always asks for my help.

使用要点：1) 时态呼应。

主句用将来时，从句用现在时；主句是过去时，从句也用过去的某种时态。

2）位置。

从句可以位于主句之前，也可以位于主句之后。

从句在前时，主从句之间用逗号隔开。
