状语从句知识点详解(初中英语专项复习)14

状语从句知识点详解(初中英语专项复习)状语从句的概念: 用一个句子作状语来修饰动词和形容词,以表明动作发生或状态存在的时间、地点、原因等,这个句子就叫做状语从句。
状语从句的分类:状语从句共分为九大类,包括:时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。
下面分别讲解:一、时间状语从句概念:用来表示时间的状语从句,由when, while, as, till, until,before, after, since等引导。
由于时间状语从句的引导词所表示的意思并非一致,不同引导词表达不同的时间,它们在句子中对应的时态、语态等也有所不同。
例如:when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词,也可以是延续性动词。
从句动作可与主语动作通常先后发生也可同时发生。
I was writing when my sister came back.( come是瞬间动词,只能用when引导,不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词,while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词,cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋,而我姐姐喜欢看小说。
(while表示对比)when和while的区别还有: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 we were playing games, our headmaster called me .我们正在做游戏的时候,校长叫我了。
初中英语语法——状语从句

状语从句一、考点解读今天我们复习状语从句,英语中状语与中文的状语大致相同,分为时间状语、地点状语、原因状语、目的状语、结果状语、条件状语、方式状语等等。
如果一个主从复合句中的从句是用来表示时间,原因等等时,那就称为状语从句。
在主从复合句中修饰主句中的动词、形容词、副词等的从句叫做状语从句,又由于其功能与副词非常相近,又称做副词性从句。
状语从句一般可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句和方式状语从句九种。
这节课我们主要复习如下的内容:1.时间状语从句2.地点状语从句3.原因状语从句4.目的状语从句5.结果状语从句6.条件状语从句7.让步状语从句8.比较状语从句9.方式状语从句二、专题梳理(一)时间状语从句在句子中起时间状语作用的句子称为时间状语从句。
时间状语从句可以放在句首、句中和句尾。
常用来引导时间状语从句的引导词有:when 当……时候while 当……时候as 当……时候、一边after 在……之后before 在……之前since 自从ever since 自从once 一……就……whenever 不管什么时候by the time 到……as long as 长达……as soon as 一……就……till/until 直到……1.when,while,as的用法从属连词when,while,as都可用来引导时间状语从句,意为“在……时候”。
但在具体用法上又不尽相同。
(1)这三个连词中,when用得最广,常可代替while与as。
与while相比,when引导的从句动词既可是延续性的,也可是终止性的。
as在这一点上与when相同,while所引导的从句中,动词只能是延续性的。
在初中阶段,我们几乎很少讲as引导时间状语从句。
是因为as在初中阶段是一种供了解性的内容。
e.g.When the fire broke out, all the studentswere sleeping soundly.(终止性的)当火灾发生时,所有的学生正在熟睡中。

1.when, while, as引导的时间状语从句2. 比较until和till此两个连词意义相同。
肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。

Wait till I call you. 等着我叫你。
(在肯定句中可用before代替。
例如:Let’s get in the wheat before the sun sets.)否定句:She didn’t arrive until 6 o’clock. 她直到6点才到。

例题解析
1、易混引导词while, when, as的区别:
(1)when既可以指“时间点”,与瞬间动词连用,也可以指“时间段”,与延续性动词连用(=while)。
如:
When he came in, his mother was cooking.
When (While) we were at school, we went to the library every day.
(2)While表示时间段,因此,while 从句的谓语动词要用延续性动词。
如:
Please don’t talk so loud while others are working.
(3)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。
如:
As you get older, you get more knowledge.随着年龄的增长,你获得的知识就越多。
2、Because, as, since 的区别:
Because用于表示直接原因,回答why提出的问题,语气最强;As用于说明原因, 着重点在主句,常译成“由于”;since表示显然的或已知的理由或事实,常译成“既然”。
如:Water is very important because we can’t live without it.
He didn’t come yesterday as his mother was ill.
I’ll do it for you since you are busy.
3.such…that, so…that, so that 引导结果状语从句的区别:
such是形容词,修饰名词; so 是副词,修饰形容词或副词。
其结构如下:
1) such + a (n)+ 形容词+单数可数名词+that……
2) such+形容词+复数可数名词+that ……
3) such +形容词+不可数名词+that……。
如:
This was such a good film that I went to see it several times.
It was such good books that they sell well.
It was such bad weather that I had to stay at home.
He spoke so fast that I couldn’t follow him.
He is such a lovely boy that we all like him.
=He is so lovely a boy that we all like him.
注:在“形容词+可数名词复数/不可数名词”结构中,当名词前有many, much, few, little 表示数量的多少时,名词前用so。
如:
She made so many mistakes that she didn’t pass the exam.
