一、时间状语从句时间状语从句用来表示一个动作或事件的时间。

它们通常以连词when,while,before,after等开头。

1. 结构时间状语从句通常由一个从句和一个主句构成。

初中状语从句

初中状语从句

初中英语知识点归纳:状语从句一时间状语从句1.时间状语从句表示时间,引导词有:when, while, as, till, until before, after, since等。

时间状语从句的引导词所表示的意思不尽相同,要注意把握不同引导词所表示的不同时间关系,以及它在具体句子中对应的时态、语态等问题。

注意:as(在……时候,因为),since(自从,因为),它们可以引导时间从句,并强调主句和从句的动作同事发生。

并且while有时还可以表示对比。

例如:(1)While my mother was reading the newspaper, I was watching TV.(read是延续性的动词,read和watch同事发生)I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球。

(对比)(2)when(当……的时候),引导的从句的谓语动词可以是延续性动词,也可以是瞬间动词。

从句动作可与主语动作同事发生,也可在其后发生。

I was reading a book when she came into my room(come是瞬间动词,只能用when引导,不能用while)I often missed my home when(while) I lived in New York.(live是延续性动词,when可用while代替)(3)when和while的区别还在于:while引导的时间状语从句多用于进行时态,而when引导的时间状语从句多用于一般时态。

While they were talking, the bell rang.正在他们谈话的时候,上课铃响了。

(4)as译作“一边……一边”、“随着……”,侧重主句和从句的动作同时发生。

有时可与when,while通用。

We always sing as we walk.我们总是边走边唱。

八种状语从句

八种状语从句

八种状语从句状语从句在句中作状语,修饰主句中的动词、形容词和副词等。

按其作用和意义可分为时间、原因、目的、结果、条件、让步、方式、比较八种。

下面对这八种从句的要点加以总结。

一、各类状语从句的引导词及易混词的区别。

1. 时间状语从句1) 引导词(1)表示“当……时候”:when, while, as, whenever(2)表示“一……就……”:as soon as(3)其它:after, before, since, until, by the timeWhenever he comes, he brings a friend. 他每次来都带个朋友。

I want to see him as soon as he arrives. 他一来我就要见他。

I went to bed after I finished my homework. 我做完家庭作业之后才睡觉。

2) 易混引导词when, while, as 的区别when既可指“时间点”,与瞬时动词连用,也可指“时间段”,与延续性动词连用(这时可与while互换)。

如:When he came in, his mother was cooking. 他进来时,他妈妈正在烧饭。

When(While)we were at school, we went to the library every day. 我们在校求学时,每天都到图书馆去。

while 只表示时间段,因此while从句的谓语动词要用延续性动词。

Please don' t talk so loud while others are talking. 别人在工作时,切勿大声讲话。

as 与when 用法相似,但着重强调主句动作与从句动作同时发生,有“随着……”或“一边……一边……”之意。

She sang as she went along. 她边走边唱。

As you get older, you get more knowledge.随着年龄的增长,你获得的知识就越多。
