英语中的定语从语，宾语从句，状语从句的详解

定语从句就是一个从句在整个句子中充当定语的成分

宾语从句就是一个从句在整个句子中充当宾语的成分

状语从句就是一个从句在整个句子中充当状语的成分

定语从句

（一）、定义：在复合句中，修饰某一名词或代词的从句叫做定语从句。

定语 定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语（动词不定式短语、动名词短语和分词短语）或句子，汉语中常用‘……的"表示。主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任。单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。

定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后。

如：1) The man who lives next to us is a policeman.

2) You must do everything that I do.

上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。

引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why

关系词常有三个作用：1、引导定语从句 2、代替先行词 3、在定语从句中担当一个成分

（二）、关系代词引导的定语从句

1.who指人，在从句中做主语

(1)The boys who are playing football are from Class One.

(2)Yesterday I helped an old man who lost his way.

2. whom指人，在定语从句中充当宾语，常可省略。

(1) Mr. Liu is the person (whom) you talked about.

注意：关系代词whom在口语和非正式语体中常用who代替，可省略。

(3) The man who/whom you met just now is my friend.

3. which指物，在定语从句中做主语或者宾语，做宾语时可省略

(1) Football is a game which is liked by most boys. ( which 在句子中做主语)

(2) This is the pen (which) he bought yesterday. ( which 在句子中做宾语)

4. that指人时，相当于who或者whom；指物时，相当于which。

在宾语从句中做主语或者宾语，做宾语时可省略。

(5) The people that/who come to visit the city are all here. (在句子中做主语)

(6) Where is the man that/whom I saw this morning? (在句子中做宾语)

5. whose通常指人，也可指物，在定语从句中做定语

(1) He has a friend whose father is a doctor.

(2) I lived in a house whose roof has fallen in.

whose指物时，常用以下结构来代替

(3)The classroom whose door is broken will soon be repaired.

=The classroom the door of which is broken will soon be repaired.

(5)Do you like the book whose color is yellow?

=Do you like the book the color of which is yellow?

注：that 用法

(1)不用that的情况

(a) 在引导非限定性定语从句时。

(错)The tree, that is four hundred years old, is very famous here.

(b) 介词后不能用。

We depend on the land from which we get our food.

We depend on the land that/which we get our food from.

(2) 只能用that作为定语从句的关系代词的情况

(a) 在there be 句型中，只用that，不用which。

(b) 在不定代词，如：anything, nothing, the one, all等作先行词时，只用that，不用which。

(c) 先行词有the only, the very,the same,the last,just修饰时，只用that。

(d) 先行词为序数词、数词、形容词最高级时，只用that,不能用which。.

(e) 先行词既有人，又有物时。

(f) 先行词指物，在主句中作表语时．

(g) 为了避免重复．

(h)先行词是the way或the reason时，that可作关系副词，也可省略

(i) 主句的主语是疑问词who /which时

举例：

Is this the book that you borrowed in the library?

这是你在图书馆借的那本书吗？

Who that break the window should be punished．

谁打碎了窗户都要受到惩罚．

All that is needed is a supply of oil.

所需的只是供油问题。

Finally, the thief handed everything that he had stolen to the police.

那贼最终把偷的全部东西交给了警察。

（三）、关系副词引导定语从句

关系副词 关系副词：在句中作状语

关系副词=介词+关系代词

why=for which

where=in/ at/ on/ ... which (介词同先行词搭配)

when=during/ on/ in/ ... which (介词同先行词搭配)

1. where指地点，在定语从句中做地点状语用来表示地点的定语从句。

(1) Shanghai is the city where I was born.

(2) The house where I lived ten years ago has been pulled down.

2. when引导定语从句表示时间。在定语从句中做时间状语也可做连接词用

(1) I still remember the day when I first came to the school.

(2) The time when we got together finally came.

[注]表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。

By the time you arrived in London, we had stayed there for two weeks.

到你到达伦敦的时候，我们在那里已经待了两个星期。

I still remember the first time I met her. 我仍然记得我第一次见到她。

Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。

每一次他去出差，他带来了生活必需品，如毛巾，肥皂，牙刷等，很多。

3. why指原因 在定语从句中做原因状语

(1) Please tell me the reason why you missed the plane.

(2) I don"t know the reason why he looks unhappy today.

注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换

(1) The reason why/ for which he refused the invitation is not clear,

(2) From the year when/in which he was going to school, he began to know what he wanted when he grew up.

注：1）介词后面的关系代词不能省略。

2）that前不能有介词。

3） 某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同

关系副词when ,where和why 互换。

This is the house in which I lived two years ago.

This is the house where I lived two years ago.

Do you remember the day on which you joined our club?

Do you remember the day when you joined our club?

This is the reason why he came late.

This is the reason for which he came late.

宾语从句

（一） 宾语从句的种类

宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。根据引导宾语从句的不同连词，宾语从句可分为三类。

1. 由that引导的宾语从句。that只有语法作用，没有实在的意义，在口语

和非正式文体中可以省略。例如：

He said (that) he wanted to stay at home.

She doesn"t know (that) she is seriously ill.

I am sure (that) he will succeed.

2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如：

Do you know who (whom) they are waiting foe?

He asked whose handwriting was the best.

Can you tell me where the No.3 bus stop is?

I don"t know why the train is late.

3. 由if或whether引导的宾语从句。if和whether在句中的意思是“是否”。例如：

I want to know if (whether) he lives there.

He asked me whether (if) I could help him.

（二）宾语从句的语序

宾语从句的语序应为陈述句的语序。例如：

I hear (that) physics isn"t easy.

I think (that) you will like this school soon.

Can you tell me how I can get to zoo?

Please tell me when we"ll have the meeting.

（三）宾语从句的时态

1. 如果主句的时态是一般现在时，宾语从句该用什麽时态就用什麽时态。

如： I don"t think (that) you are right.

Please tell us where he is.

Can you tell me how I can get to the railway station?

2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时， 过去进行时， 过去将来时，过去完成时）。例如：

He asked what time it was.

He told me that he was preparing for the sports meet.

He asked if you had written to Peter.

He said that he would go back to the U.S. soon.

3. 如果宾语从句所陈述的是客观真理，其时态常用一般现在时。例如：

Our teacher said that January is the first month of the year.

Scientists have proved that the earth turns around the sun.

状语从句

状语从句

状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句， 原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。

1. 时间状语从句

(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如：

It was raining hard（rain hard 下大雨） when got to school yesterday.

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.

After he finished middle school, he went to work in a factory.

(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：

I"ll ring you up as soon as I get to New York.

I will tell him everything when he comes back.

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.

Don"t get off（从下来） until the bus stops.

【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。 Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。固定组合里from morning till night，till/until是不能替换的，】

2. 条件状语从句

(1)条件状语从句通常由if, unless引导。例如：

What shall we do if it snows tomorrow?

Don"t leave the building unless I tell you to.

(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：

I"ll help you with your English if am free tomorrow.

He won"t be late unless he is ill.

(3)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如：

Hurry up, or you"ll be late. =If you don"t hurry up, you"ll be late.

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.

As it is raining, we shall not （不得；不应该）go the zoo.

Since you can"t answer the question, I"ll ask someone else.

(2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如：

------Why aren"t going there?

------Because I don"t want to.

As he has no car, he can"t get there easily.

Since we have no money, we can"t buy it.

(3)because和so不能同用在一个句子里。

4. 结果状语从句

(1)结果状语从句由so…that, such…that, so that引导。例如：

He is so poor that he can"t buy a bike for his son.

She is such a good teacher that everybody likes her.

My pencil fell under the desk, so that I couldn"t see it.

(2)so…that语such...that可以互换。例如：

在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是: “...so + 形容词（副词）+ that + 从句”。例如：

He was so glad that he couldn"t say a word.

The hall is so big that it can hold 2,000 people.

Mother lives so far away that we hardly ever（几乎不，从来不） see her.

在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或an。例如：

It was such a hot day that nobody wanted to do anything.

He had such long arms that he could almost touch the ceiling.（天花板）

He made such rapid progress that he did very well in the mid-term.

有时上述两种结构是可以互换的。例如：

It was such a wonderful film that all of us wanted to see it again.

=The film was so wonderful that all of us wanted to see it again.

It is such an important match that nobody wants to miss it.

=The match is so important that nobody wants to miss it.

(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。例如：

Soon there were so many deer that they ate up all the wild roses.

He has so little time that he can"t go to the cinema（去看电影） with you.

5. 比较状语从句

比较状语从句通常由as…as, 比较级 + than…等连词引导。例如：

Tom runs faster than John does.

This classroom is as big as that one.

6. 目的状语从句

(1)目的状语从句通常由 so that, in order that（为了，以便）引导。例如：

We started early so that we could catch the first train.

He studies hard so that he could work better in the future.

We used the computer in order that we might save time.

(2)so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：

Speak clearly so that they may understand you. (目的状语从句)

Jack is badly ill so that he has to rest. (结果状语从句)

7. 让步状语从句

(1)让步状语从句通常由although, though等连词引导。例如：

Though he is young, he knows a lot.

Although I am tired, I must go on working.

(2)although(though)不能用在同一个句子中。例如：

我们不能说：Though it was raining hard, but he still went out.

应该说：Though it was raining hard, he still went out.或It was raining hard, but he still went out.

8. 地点状语从句

地点状语从句常常由where来引导。例如：

Go where you like.

Where there is a will, there is a way.

总结：状语从句分类及常用连词：

类别　　　　　　　　连　　　　词

时间状语从句　　when, whenever, while, as, before, after, since, till, once（一旦）

地点状语从句　　where, wherever

原因状语从句　　because, since, as, for, now that（既然，由于）etc. （et cetera，等于and so on）

目的状语从句　　in order that(为了，以便), so that, that, etc.

结果状语从句　　so…that, so that, such…that, that, etc.

条件状语从句　　if, unless, as(so)long as, etc.

让步状语从句　　though, although, even if, even though, however, whatever, as, etc.

比较状语从句　　as…as, so…as, than, etc.

方式状语从句　　as, as if, as though, etc.

根据英语从句在句子中的句法作用，从句可分为三类：名词性从句，形容词性从句和副词性从句。通过对引导从句的各种引导词进行观察，我们不难发现，有的从句可以直接从引导词的形式和意义上来区分。如：Though the old man is over seventy, he still sees well and hears well. 我们一读此句，就可以认定，由Though引导的从句是一个让步状语从句。因为though只能引导让步状语从句，不能引导其它从句，但是有些引导词却能引导多种从句。如引导词when：既可以引导时间状语从句又可以引导定语从句，还可以引导名词性从句。此外，象that，where等，三类从句均可引导；who既可引导定语从句，又可引导名词性从句；so that 即可引导目的状语从句，又可引导结果状语从句……因此，这些形同义不同的引导词给我们理解、掌握、运用各种从句带来了很大困难。另外，搞不清楚从句在句子中所起的作用，就不能正确理解原文。那么，怎样正确区分各种形同义不同的引导词引导的从句呢？

1、 分析句子结构以区虽从句的种类 遇到一个复合句，首先要分析其句子结构，看从句在整个句子中起什么作用，那么它就是什么从句。

2、 分析引导词的句法作用以区别从句的种类 that这个词即是引导同位语从句，又可引导定语从句，这种两种从句从形式和结构上看特别相似，如何区分呢？ 区分that引导的是同位语从句还是定语从句的方法是，看that在从句中是否充当句子成分，若that在从句中不充当任何成分，则为同位语从句；若that在从句中充当主语或宾语，则为定语从句。

3、 根据被修饰词来判断从句的种类 定语从句常常修饰一些具有实际意义的名词，如：the film；the student；the book；a house等等。而同位语从句常常修饰一些表示抽象概念的名词，如fact、idea、promise、truth等，用来说明这些名词所表示的具体内容。状语从句在句子中常用来修饰谓语动词。

4、 根据从句前词的词性来判断从句的种类 宾语从句分两种：动词的宾语从句、介词的宾语从句。宾语从句前肯定是动词或介词。定语从句是用来修饰名词或代词的，所以其前一定是一个名词或代词。

5、 根据上下文意义和结构形式上区分从句的种类 如so that即可引导目的状语从句，又可引导结果状语从句，如何区分呢？主要从以下两点来区分。 ①根据上下文意义判断。“以便……”表示目的，是目的状语从句，“以致于……”，“结果……”表示结果，是结果状语从句。 ②从结构形式上来分辨。so that前有逗号，为结果状语从句，反之，则为目的状语从句。有时，so that前无逗号，这里要看从句中有无can、could、may、might、will、would、should 等情态动词，如果有，则多是目的状语从句，若没有，则多是结果状语从句
