While作为并列连词,意思为“而,然而”,表前后意义上的对比或转折。
例如:There’s plenty of rain in the southeast,while theres little in the northeast.东南部雨量充足,而西北部则很少下雨。

  另外while还有别的用法,while引导状语从句,有以下两种含义:

  1.表示某个动作正在进行的'同时,另一动作也在进行之中,这时主从句都用进行时态,有对同类的两个动作进行对比的意味.如:

  While I was playing the piano,she was dancing.我在弹钢琴,她在跳舞.

  While Jim is picking apples,Kate is carrying apples to the truck.吉姆正在摘苹果,凯特正在把苹果搬到卡车上去.

  2.表示某个动作正在进行时,又发生了另一动作(该动作用一般过去时).如:

  While I was reading,I fell asleep.我读着读着就睡着了.

  While we were swimming in the river,we saw a fish jump out of the water.我们正在河中游泳时,看见一条鱼跃出了水面.
