时间状语从句知识点归纳

时间状语从句知识点归纳

时间状语从句知识点归纳when/while/as 当……时,随着(一)when:表示“时间点”1. When my mother came into the house(=When coming into the house), she found me lying there awake .当我妈妈走进屋子时,发现我醒着躺在那。

这个句子主句是一般过去时,从句是一般过去时。

同时要注意,当从句主语和主句主语一致时,往往可以省略从句的主语,将从句谓语转化为现在分词形式即“when+Ving”这种短语形式代替状语从句;(二) while:表示“时间段”1、while they are arranging everything for their children, they are also interfering their growth.当他们在为子女安排一切的同时, 也在干涉他们的成长。

请大家注意以下几点:A. While译为“当...时”或“在…期间”,while引导的从句通常为进行时,即指一段时间,表示从句动作在进行时,主句动作也在进行中,所以此时主句一般也是进行时;B. While还能译为“趁”和“虽然/然而”,while译为“虽然/然而”时是让步状语从句。

如果发现while引导的状语从句与主句方向相反时,肯定是让步状语从句,表示“虽然/然而”,这一点要区分清楚。

(三)as:表示“随着”1、As Tony listened to those words, smile appeared on his face.随着托尼听到这些话, 微笑出现在了他的脸上。

这个句子主句是一般过去时,从句也是一般过去时。

A. As引导的从句侧重于表示主句发生的背景和条件,所以一般不为进行时,主句也不是进行时;B. As一般译为“随着”,当然也可以理解为“当…时”,不过从句的动作有持续发展之意,这一点不同于when/while。

I waited till the rain stopped. 我一直等到雨停。 He didn’t give me the answer until I asked him the second time. 直到我问了第二次,他才回答我 的问题。

As children get older, they become more and more interested in things around them.
随着孩子年龄的增大,他们就会对 他们周围的事情越来越感兴趣。
