【即时应用】
①——I’m going to the post office.
——______you’re there, can you get me some stamps?
A. As B. While C. Because D. If

2)while还可以用作从属连词，作“在„„期间”，“当„„时候”讲，使用时应注意它与用作从属连词的when的区别：
when引导的时间状语从句，即可表示“一段时间”，又可表示“一点时间”，因此从句的谓语动词既可以是延续性的，也可以是非延续性的。如：
①I hope to see you when(while)I stay in Beijing on business.
(一段时间)当我出差北京时，希望见到你。
②When the clock struck twelve, all the lights went out.
(一点时间)当钟敲响十二下时，灯全部熄灭了。
【注意】while引导的时间状语从句只能表示“一段时间”所以 while从句的谓语动词应是延续性动词(或状态动词)。例如：
①While I stayed(or was) in Shanghai, I saw her three times.
我在上海期间见到她三次。
如果从句的谓语动词是延续性的，可以用while也可以用when。例 如：
②While(When) we were having a meeting, a stranger came in.
我们在开会时，一个陌生人走了进来。
