所谓when和while,都是关系副词。中文翻译为“当…的时候”、“在…的时候”等。它们在用法上有所差异。

1. when 用法:when 通常引导的是时间状语从句。

例如:

① I was taking a shower when the phone rang. (我正在洗澡的时候电话响了。)

② When she was young, she wanted to travel the world. (她年轻的时候想周游世界。)

2. while 用法:while 也可以引导时间状语从句,但要表示的时间段必须要长。

例如:

① She had to wait for half an hour while the doctor was in surgery. (医生在手术时,她等了半小时。)

② You should listen carefully while the teacher is speaking. (老师在讲课的时候你应该认真听。)

另外,while 还有“然而,尽管”的意思。

例如:
