【点拨】while连词,意为"尽管;虽然";其用法大致有以下四种用法:1.引导时间状语从句,意为"当……的时候;和……同时",此时的主从句谓语动作同时发生,从句谓语通常是延续性动词。
e.g. Mary watched TV while she ate her supper.
玛丽边吃饭边看电视。While she was listening to the radio, she fell asleep.
她听着收音机睡着了。
while引导从句时,如主从句的主语一致,且从句谓语又含有be,则从句主语和be可省略。while后可直接跟现在分词、名词、形容词或介词短语。

appeal to the general readers.
这本书受到学者的欢迎,同时也会引起一般读者的兴趣。
6.意为"趁着"。
