中考英语积累:while用法面面观
一、while用作名词时,意为“一段时间,一会儿”。
例如:I stayed there for a short while.(我在那儿呆了一小会儿。)
The postman came a short while ago.(邮递员刚刚来过。)
二、while用作连词时,有以下几种含义:
1.意为“当……时候,和……同时”,引导时间状语从句。例如:While I was watching TV, the bell rang.(我看电视时,铃响了。)
Meimei watched TV while she ate her supper.(梅梅边吃晚饭边看电视。)
2.意为“虽然,尽管”,引导让步状语从句。例如:
While it was late, he went on working.(虽然很晚了,但他还在继续工作。)
While he is in poor health, he works hard.(虽然他身体不好,但他还是努力工作。)
3.连接两个并列句子,表示“对比”关系。例如:

I like singing while she likes dancing.(我喜欢唱歌,而她喜欢跳舞。)
You like sports, while I prefer music.(你喜欢体育,而我更喜欢音乐。)
三、while引导状语从句时,请注意:
while引导的时间状语从句既可放在句首,也可放在句末;而while引导的让步状语从句一般放在句首,不放在句末。另外,也可以从意义上加以区分。例如:
While he was tired, he went on working.(虽然他累了,但他还是继续工作。)
