同学你好
while的具体用法
1、“当……时候”，引导时间状语从句(从句动作必须是延续性的)。

Please don't talk so loud while others are working. While I was cleaning  the window, my finger was seriously cut.

2、“虽然，尽管”相当于although，引导让步状语从句(常把while放在句首)。

While she is a top student， she has some shortcomings.

3、“只要，如果”等于as long as，引导条件状语从句。

While you study hard， your effort will pay off.
祝学习愉快哦
