while词语用法:
1、while用作连词时,表示“在…(过程)中,在…期间”。常用来引导时间状语从句,当主句的主语和while所引导的从句的主语一致时,while从句中的主语、谓语往往可以省去。
2、while还可引导让步状语从句,意思是“虽然,尽管”,含有对比意味。
词义辨析:
nevertheless,while,whereas这些连词或副词均含“但是,可是,然而,而”之意。
1、nevertheless指尽管作出完全让步,也不会发生任何影响。
2、while表对比,一般可与whereas换用,但程度弱一些。
3、whereas表对比,一般可与while互换。
例如:
She likes to lie down for a while after lunch.
她喜欢午饭后躺一会儿。

①While there is life ,there is hope.只要生命存在,就有希望。
