1.-I'm going to the post office.
-_____you're there,can you get me some stamps?
A.As B.While
正确答案是B,麻烦详细解释一下as和while的区别.
2.If you are sent to work ____ you are not used to the people's life style,be sure to adapt yourself to them as soon as possible.
A.where B.in which
麻烦也详解一下这两个词.
最好能通俗一点.

1.两个都有"与.同时"的意思,有一些区别as只用于是陈述已经发生的事件,一个事情和另一事情同时发生的.while还可以表示"当.的时候",可以做一个条件句来用.
可以说As he were there,he got me some stamps.
但不能说As you're there,can you get me some stamps?
另:I'm going to the post office.说明我还在路上,所以无论如果都不能用AS
as用做"由于"的时候,也只能做为已经发生的事情的理由.
2.in which在引导定语从句的时候相当于where
这题是状语从句没用in which这样的用法
