1、主体上在于后面谓语动词上的区别:
while引导时间状语从句,从句中的谓语需要用延续性动词或者是形容状态的词。
如:While the discussion was still going on,George came in.
当讨论还在进行时,乔治走了进来。
而让步状语从句时态较为随意。
While he loves his students,he is very strict with them.
虽然他爱他的学生,可是他对他们很严格。
2、翻译上的区别:
引导让步状语从句,经常用在句首。翻译为:尽管,虽然。
如:While I admit his good points I can see his bad.
尽管我承认他的长处,但我也看到了他的不足。
而时间状语从句不一定仅仅放在句首。翻译为:当什么时候
如:Strike while the iron is hot.
趁热打铁。
3、这就是最主要的区别,另外,while还常常作并列连词用,意思为“而,然而”,表前后意义上的对比或转折。
如:There’s plenty of rain in the southeast,while there's little in the northeast.
东南部雨量充足,而西北部则很少下雨。
Some people waste food while others haven't enough.
有些人浪费粮食,然而有些人却吃不饱。
扩展资料:
While用法:
1、while作名词用,表示“一会儿”“一段时间”
例句:She likes to lie down for a while after lunch.
她喜欢午饭后躺一会儿。
2、While作连词引导时间状语
例句:We must strike while the iron is hot.
趁热打铁。
3、引起让步状语从句,意思是“虽然…但是….”,“尽管…但是…”(多放于句首)。
例句:While he loves his students,he is very strict with them..
虽然他爱他的学生,可是他对他们很严格。
4、引起条件状语,意思是“只要”。
While there is life there is hope.
只要生命存在,就有希望。
While there is a way there is away.
有志者事竟成。
5、While作并列连词用,意思为“而,然而”,表对比。而but表转折。注意用心比较体会while与but的句中用意
Some people waste food while others haven't enough.
有些人很费粮食,然而有些人却吃不饱。
