在复合句中,修饰主句中的动词、形容词或副词等的从句叫状语从句。状语从句根据它表达的意思可分为时间、地点、原因、目的、结果、让步、比较(或方式)和条件等类。

1.时间状语从句

引导连词有when,while,till,notuntil,since,after ,before ,as soon as

他没有看那部电影,因为他已经看过了。

They couldnt get on the train,for it was too crowed.

比较:because, since, as和for

1)because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或已为人们所知,就用as或since。

I didnt go, because I was afraid.

Since /As the weather is so bad, we have to delay our journey.

2)由because引导的从句如果放在句末,且前面有逗号,则可以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,

就只能用for。

He is absent today, because / for he is ill.

He must be ill, for he is absent today.

注意:because不能和so 连用。

4.目的状语从句

引导连词有that,so that,in order that。

So that 以便/以致

例如:

(1)They studied hard so that they could pass the exam.

(2)They started early so that they caught the early bus.

注意点:

在例句(1)中,是引导目的状语;在例句(2)中,是引导结果状语。一般来讲,从句中含有情态动词的,为目的状语。无情态动词的,为结果状语。

5.结果状语从句

引导连词有that,sothat,such.that

The box is so heavy that I cant lift it.

这个盒子如此沉,以致我无法抬起来。

such+名词性词组+that

So+形容词/副词+that如此以致

例如:

(1)She is such a good teacher that we all love her.

(2)It was such a hot day that they didnt go out for a walk as usual.

注意点:

1.such+a+形容词+名词+that,可以改写成:so+形容词+a+名词+that

例句(1)可以改写成:She is so good a teacher that we all love her.

2.在such+形容词+名词复数或不可数名词+that结构中,形容词如果是many/few或much/little时,用so不用such,即:so+many/few+可数名词复数+that,so+much/little+不可数名词+that

(1)There are so many people in the room that I cant get in.

吉姆比路希年长。

如果你吃到坏了的食物,就会生病。

If it doesnt rain tomorrow, we will have a sports meet.

注意:主句是将来时,从句用一般现在时。

状语从句中常见的误点

1) 时间状语从句和条件状语从句中的时态与主句的搭配:(俗称:主将从现)

2) 原因状语从句because与because of ;

Because+从句和because of +n./ pron

例如:

初中英语语法学习建议

总是站在系统的高度把握知识

很多同学在学习中习惯于跟着老师一节一节的走,一章一章的学,不太对意章节与学科整体系统之间的关系,只见树木,不见森林。随着时间推移,所学知识不断增加,就会感到内容繁杂、头绪不清,记忆负担加重。事实上,任何一门学科都有自身的知识结构系统,学习一门学科前最先应了解这一系统,从整体上把握知识,学习每一部分内容都要弄清其在整体系统中的位置,这样做往往使所学知识更容易把握。

追根溯源,寻求事物之间的内在联系

学习最忌死记硬背,特别是理科学习,更重要的是弄清楚道理,所以不论学习什么内容,都要问为什么,这样学到的知识似有源上水,有木之本。即使你所提的问题超出了中学知识范围,甚至老师也回答不出来,但这并不要紧,要紧的是对什么事都要有求知欲,好奇心,这往往是培养我们学习兴趣的重要途径,更重要的是养成这种思考习惯,有利于思维品质的训练。

发散思维,养成联想的思维习惯

在学习中我们应经常注意新旧知识之间、学科之间、所学内容与生活实际等方面的联系,不要孤立的对待知识,养成多角度地去思考问题的习惯,有意识地去训练思维的流畅性、灵活性及独创性,长期下去,必然会促进智力素质的发展。

语法的关键性是很重要的。对于初中生来说,这个时候才刚开始学习语法,要具备熟练的语法技巧,才能够把握住英语这门课程的成绩。语法怎样才能够运用自如。英孚英语告诉你,使用英孚英语提供的语法技巧,根据技巧去结合语法共同使用着。将语法举一反三的放在文章中去使用着。

While he was doing his homework, the telephone rang. As he walked along(沿着走)the lake, he sang happily. He had learned a little Chinese before he came to China.

He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里 如果主句用肯定式,其含义是“一直到……时”,谓语动词只能用延续性动词。 如果主句用否定式,其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。 例如: The young man read till the light went out(熄灭). Let’s wait until the rain stops. We won’t start until Bob comes.

Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如: He didn’t come to school because he was ill.

初中英语语法专题讲解--状语从句

一,状语从句 状语从句在主从复合句中修饰主句中的动词、形容词或副词等,起副词的作用。状语从句由从属连词引导,从属连词在从句中不担任任何句子成分。状语从句可位于主句之前,也可位于主句之后。位于主句之前,一般要加逗号与主句分开;位于句末则不需要。状语从句根据它所表达的意思可分为时间、地点、原因、目的、结果、比较,让步、方式和条件状语从句等类。 (一),时间状语从句引导时间状语从句的从属连词有:when, while, as soon as, before, after, since , till, until 等 【注】1,until (till) 直到,在用until 表达时间状语的句子中,主句中的动词是要十分小心去选择。如动词是持续性动词,它要用肯定句,如:I studied hard until 12 o'clock last night. 如果动词是瞬间截止性动词,则要用否定句,即,not---until “直到…才”。如:He didn't go to bed until his mother came back.They didn’t stop until they finished t he work . 2,时间状语从句中的谓语动词不能用,将来时,终能用一般现在时表示一般将来时,即“主将从现”原则。如, When he comes, I’ll tell him about it. I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话 (二),条件状语从句通常由从属连词if,unless等引导 【注】1,条件状语从句与时间状语从句一样,从句中不能用将来时态,要用一般现在时态表示一般将来时态,也符合“主将从现”原则。如, If it snows tomorrow, we will build a snowman. If it rains, they won't go to the park on Sunday I won’t go to his party unless I am invited . ,2,要区别是条件、时间状语从句还是宾语从句,因为在宾语从句中该用什么时态用什么时态,如: I want to know if he will come here tomorrow I want to know if it will rain tomorrow. If it doesn’t rain, I will go hiking. I don’t know when he will come, When he comes, I’ll tell him about it. (三),让步状语从句通常由从属连词though(although)(虽然,尽管),even if(even though)(即使)等引导注:翻译是后半句带有转折的意味,但不能由but连接。 有although或though就不能有but,如, Although they are poor, they are happy. Although he didn’t pass the exam ,his father didn’t get angry with him . (四),目的状语从句通常由从属 so that,in order that等引导,意为“以便,为了”并且这种从句中的谓语一般有情态动词may,might,can,could等如, Speak clearly so that they may understand you. He got up very early so that he could catch the early bus (五),结果状语从句由so…that…、such….that…(如此…..以致于…)引导结果状语从句。其区别为:so+形容词/副词+that(如此…以至于),such+(a/an)+形 容词+名词+that(如此…以至于)如, It was raining so hard that we couldn’t see the road . She is such a beautiful girl that everyone likes her (六)原因状语从句由because 、since 、as(因为、既然、由于)引导的原因状语从句。如,Because it was wet, he took a taxi.

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 students were sleeping soundly.(终止性的) 当火灾发生时,所有的学生正在熟睡 中。 The telephone rang while I was taking a bath.(延续性的) 我在洗澡时电话响了。
