时间状语从句是指用时间的连词来连接一个句子作状语的复合句。连接时间状语从句的连词有:when、as、which等等。当as引导时间状语从句的时候,其含义是“一边…一边…”。下面我们来看一下,when、while与as在引导时间状语从句时的区别:
一、as引导时间状语从句的时候,其动作必须是可延续性的动作。主要是用来强调主句和从句动作同时发生的,当然as也可以用来强调动作的先后顺序。比如:He sang as he walk in the road.他在路上边唱歌边散步。I is doing my homework as my mother is cooking the dinner.当我妈妈在做晚饭的时候,我正在做作业。As we going to the supermarket, it began to rain.当我们出门去超市的时候,外面开始下雨了。
二、when引导时间状语从句的时候,其动作可以是延续性的动作,也可以是瞬时动作。比如:when he achieved home, I finished my homework.当他到家的时候,我已经完成了作业。When I lived in this town, I used to eating lunch in this room.当我在镇子上住的时候,我经常在这间房里面吃午饭。When we going to the movies, he came back there.当我们准备去看电影的时候,他回到了这里。
三、While引导时间状语从句的时候,其动作必须是延续性的。主要是为了强调主句和从句的动作同时发生。比如:While my mother was watching TV, my father was playing the telephone.当我妈妈在看电视的时候,我爸在玩手机。While the teacher is teaching ,I is reading the noval in the class.当我的老师在讲课的时候,我正在看小说。I eating the breakfast, while my teacher caming the classroom.当我在吃早餐的时候,老师走进了教室。
