while后面直接加动词时一般要分为两种情况。如果该动词和主句主语之间为主动关系,则一般用动词现在分词形式即Ving。但是,如果该动词和主句主语之间为被动关系时,则用其过去分词形式。
while用法:
一、while作名词用,表示“一会儿”“一段时间”。
二、While作连词。
1、引导时间状语。
2、引起让步状语从句,意思是“虽然但是”、“尽管但”(多放于句首)。
3、引起条件状语,意思是“只要”。
三、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。
四、while,when,as的用法区别。
都译为“当的时候”,区别为:when后的从句谓语动词既可是延续性动词,也可是短暂性动词,而且还可作并列连词,译为“这时”。
