英语三大从句的知识我想要三大从句完整的知识讲解

优质解答

以下这些是我整理出来的,估计你看懂后,这块是绝对没问题的!

o(∩_∩)o...呵呵

从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子.在英语中,主要有三大从句,即名词性从句（包括主语从句,宾语从句,表语从句,同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）.

主语从句用作主语,如：：

That the earth is round is true. 地球为圆的是真实的.

宾语从句用作宾语.如：

Do you know where he lives?

表语从句用作表语,如：

My opinion is that you should not go alone. 我的意见是你不应单独前往.

同位语从句用于解释说明前面的名词.如：

The fact that the earth is round is true. 地球是圆的的事实是真实的.（that从句用于解释说明the fact）

定语从句相当于一个形容词,用于修饰前面的名词.如：

The student who answered the question was John. 回答问题的学生是John.

状语从句相当于一个副词,如：

When it rains, I usually go to school by bus. 天下雨时,我通常坐公共汽车上学.（时间状语）

If he comes tomorrow, you will see him. 如果他明天来,你就可以看见他.（if 引导的条件状语从句,其结构为：if +状语从句,＋主句）.要注意在状语从句中有一个规则是“主将从现”,即主句是将来时,则从句要用一般现在时表示将来.

主句和从句的划分方法是相同的.句子的成分从谓语动词处来划分比较容易.谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语.如：

I am a teacher. 其中,I 是主语,am是谓语,a teacher 是表语.

He likes playing football very mucy. 其中,he是主语,likes是谓语,playing football是宾语,very much是状语.

名词从句、定语从句

名词从句

名词从句有四类：宾语从句、主语从句、表语从句、同位语从句.例如：

宾语从句：I don’t know where he will go.

主语从句：Where he will go is unknown.

表语从句：The problem is how we can get so much money.

同位语从句：We all feel sorry about the news that he failed in the game.

下面几点是学习名词从句要加以注意的：

1． whether和if都可以引导宾语从句表达“是否”意,（即引导宾语从句时if和whether

可以互换）但以下几种名词从句要用whether（不用if）引导：

（1） 引导主语从句,且在句首时.例：Whether he has won the tennis is not known.(但

It is not known whether/if he has won the tennis).

（2） 引导表语从句时.例The problem is whether he can get a job.

（3） 引导同位语从句时.例：I have no idea whether he will come.

（4） 介词后的whether从句.例：I worry about whether I hurt her feelings.

2． 位于句首引导主语从句的that不可忘.

例如：That he got the first place in the competition surprised all of us.

3． 在“It is suggested/proposed/ordered/a pity/no wonder/necessary/strange/…＋

that从句”结构中,that从句谓语有时用（should）do这样的虚拟语气形式.

例如：It is suggested that we(should) improve the relations between us.

It is a pity that one(should) stay in one place all one´s life.

It is strange that she should have failed to see her own shortcomings（缺点）.

4． 在“The reason why…is that…”句式中that不要误为because.

例如：The reason why he didn´t go to school yesterday is that he was ill.

5． 名词从句中that,what用法比较：

引导名词从句的that是连词,在句中无成份,无意义,而what是连接代词,what＝the

thing(s) that.

例如：It was told in yesterday´s newspaper that what the students had done was praised

by the factory.

I know that he will study.

I know what he will study.

That he works hard at his lessons is known to us all.

What he works hard at is known to us all.

All I ask is that you should tell the truth./He is not what(＝the person that)he

used to be.他和以前大不相同了.

6． where在名词从句中的使用特点：

where在名词从句中有时可以变为“the place where”,有时可以变为“介词＋the place where” 形式.例如：

主从：Where(＝The place where)she has gone is still unknown.

宾从：Would you please tell me where(＝the place where) Mr Smith lives?

表从：Your dictionary remains where(＝in/at the place where)you put.

同位从：Have you any idea where(＝of the place where) she is spending her holidays?

7． 无论是哪种名词从句都是陈述语序.例如：

I know where he lives./Please tell me what her name is.

当一个特殊疑问句本身就是陈述语序（即“主＋谓＋（宾）”或“主＋系＋表”结构）,将其变为间接引语（即宾语从句）时,无需改变语序.例如：

What´s the matter with him? She asked me what was the matter with him.

Who looks after your grandfather? He asked me who looked after my grandfather.

名词从句考点分析

1．They want to know ______ do to help us. (NMET)

A. what they can B. how they can C. how can they D. what can they

析：此题要选陈述语序项,故应排除C、D.又因how they can do不完整,do后无宾

语,故也应排除,只有A项既是陈述语序,且what they can do完整正确地表达出“他

们能做些什么”这一意思,故答案为A.

2．His teacher ______ he ______ bright and ______ he was worth teaching.

A.didn’t think;was;that B.thought;was;whether

C.didn’t think;was;× D.thought;wasn´t;×

析：观察题目,可知think后跟有and连接的两个并列宾语从句,这时前一个宾语从句

的引导语that可以省略,但引导后一宾语从句的that不可省略,据此,可排除C、D

两个选项.若选B项,全句意思不通,而选择A项可表达“他的老师认为他不聪明,不

值得教”这一意思,且语法结构无误,故可定A是正确答案.

3．______ is done cannot be undone.

A.How B.That C.What D.Where

析：do一般作及物动词使用,从题干看,需选一词作主语（逻辑上是done的宾语）.

而A.How,D.Where均是副词,不能作主语,故应排除.B项that一词只能在定语从句

中作主语,不能在主语从句中作主语,也应排除.只有选what(＝the thing that),才

能正确表述“凡是做的不可不做”这一意思.

4．Take care ______ you don´t make mistakes in the coming exam.

A.of that B.about that C.for what D.that

析：take care是“注意”、“当心”意,后面可跟that引导的宾语从句来表达“当心

不要…”意思,据此,该题应选D.

5．To his surprise,the umbrella was not ______ he had put.

A.which B.where C.the place D.that

析：观察题干,was not后是表语,根据where在表语从句中相当于in/at the place where,

将其置于空白处则可表达“伞不在他当初放的地方”这一意思,而C选项缺少词,不可

选.A、D项皆不合用.

6．______ we can´t get seems better than ______ we have.

A.what;what B.what;that C.that;that D.that;what

析：此题显然是要表达“我们得不到的东西似乎比我们得到的东西好.”这一意思,即

“A seems better that B”结构,根据what＝the thing(s) that这一特点,将其置

于两空白处正好可以表达出前者比后者好这一意思,故答案为A.

7．______ we’ll go camping tomorrow depends on the weather.

A.If B.Whether C.That D.Where

析：此题depends前的主语从句是一个不肯定的内容,在句首表“是否”意时,只能用

Whether,不可用If.故答案为B.

8．______ they are most interested in is ______ they can produce more and better

cars.

A.That;how B.What;how C.What;what D.That;that

析：is前面是一个主语从句,要表达“他们最感兴趣的（东西）”这一意思,只能选what

填入空白;is是表语从句,显然只有选how才能表达“如何生产更多更好的汽车”,故

答案为B.

9．He made a suggestion that the English test ______ until next Wednesday.

A.will be put off B.be put off C.will put off D.put off

析：suggestion,order,adivce等词后的同位语从句谓语要用（should）do的形式,且

该句中test与put off为被动关系,故选B.

10．I don´t think ______ he said something like that is right.

A.that B.what C.whether D.when

析：此句think后是一宾语从句,这个宾语从句的主语在is之前,它是一个被动句.

因为he said something like that已经含有主、谓、宾、状等成分,只有选不表意义,

不做成分的that才合适,故选A.

定语从句

一、 定语从句与引导词

定语从句是在复合句中修饰某一名词或代词的从句.被修饰的名词或代词叫做选行词,

而引导定语从句的词叫引导词,有关系代词和关系副词两类.

懂得什么样的先行词后用什么样的引导词是学好定语从句的关键.

1． 关系代词有：that,which,who,whom,whose,在定语从句中作主语、宾语中表语,whose

作定语.代人的有：who,whom,whose,that；代物的有：that,which,whose.例如：

The man who helped you is Mr White.(who代人,在定语从句中作主语)

That is the person(whom/who/that) you want to see.(whom,who,that代人,在定

语从句中作宾语,可省略)

I´m not the fool(that) you thought me to be.(that代人,在定从中作表语)

A dictionary is a useful book which(＝that) tells us the meaning of words(which

或that代物,在定从中作主语)

2． 关系副词有：when(指时间),where(指地点),why(指原因),在定语从句中作状语.

例如：Would you suggest a time(when) we can have a talk?(when可省略)

The house where they live is not very large./This is the reason why he did not came to the meeting.

注意：不是表时间的先行词都用when引导定从,不是表地点的先行词都用where引导定从.例如：We´ll visit the factory which(＝that) makes radios.

(which或that在定从中作主语,where不可用主语,故不可用)

They still remember the happy days(which/that) they spent in Beidaihe.

(which或that在定从中作spent的宾语,when不可作宾语,故不可用)

二、限制性定语从句与非限制性定语从句

限制性定语从句和主句之间不用逗号分开,修饰主句中的某一个名词或名词词组或代

词；非限制性定语从句常用逗号和主句隔开,可以修饰主句中的某一个词,也可修饰整个句子.非限制性定语从句不能用that引导,引导非限制性定语从句的关系词不能省略.非限制性定语从句例：Li Ping´s father, who works in a factory, is an engineer./He tore up my photo, which made me very angry.(which指代主句内容,因前后两句是因果关系,此时which不可换为as.)

He is good at physics, as is known to us all.＝As is known to us all, he is good at physics.(as指代主句内容,在as is known/believed, as we all know/believe这类结构中as不可换为which)

三、 只用that引导和不用that引导的场合

1． 只用that引导和不用that引导的场合

1） 当先行词既包括人又包括物时：He talked about the men and the books that attracted

him.

2） 指物的先行词被any, every, only, very, all, no等修饰时：These are the very points that interest me./That´s the only watch that I like most.

3） 指物的先行词被序数词或形容词最高级修饰时：The first step that we are to take is very difficult./This is the second card that he gave me.

4） 先行词是指物的不定代词all,little,few,much,及everything,anything,nothing等时：There is still much that can be done about it./Have you got everything that you need?

5） 先行词是who时：Who that have seen him does not like him?

2． 不用that的场合如下：

1）非限制性定语从句中 Last night ,I saw a very good film,which was about the Long

March .

2）介词放在关系代词之前时 This is the man from whom I learnt the news

3）句中出现了that,或先行词是that时 I have found that which I was looking for.

问题1：谁能告诉我关于三大从句的知识[英语科目]

你太懒了；

最佳答案

宾语从句：

I don't think that he can answer this question, can he?我认为他答不出这个问题,不是吗?

状语从句：

If it doesn't rain tomorrow,we will go there by bike.如果明天不下雨,我们就骑自行车去那里.

定语从句：

I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反.

状语从句：

用一个句子（从句）来作另一个句子（主句）的状语,用作状语的句子就叫作状语从句.作什么样的状语就叫什么类型的状语从句.例如：条件状语从句就是用一个句子来作条件状语.

状语从句的分类：

（1）时间状语从句

凡是从句都必须有引导词,引导时间状语从句的词有when,before,after,until,as soon as,while 等.

（2）条件状语从句

主要看一下由if引导的条件状语从句.if 意为“如果”,引导条件状语从句时,表示假如有从句的动作发生就（不）会有主句的动作发生.例如：

If it doesn't rain tomorrow,we will go there by bike.如果明天不下雨,我们就骑自行车去那里.

If I get there early,I can see the doctor quickly.如果我早早地到那里,我就可以快点看病.

3）地点状语从句用法要点

常用where（哪里）和wherever（无论哪里）eg.

Where there is a will,there is a way. 有志者,事竟成.

We will go wherever the motherland need us most. 我们要到祖国最需要的地方去.

（4）原因状语从句用法要点

常用的引导连词有because,as和since,三者的区别是：在回答问题的时候,使用because；对于显而易见的原因,常用as或since；as和since的从句常放在主句之前,而because的从句常放在主句之后.eg.

Why did you go? I went because Tom told me to go. 你为何去?那是因为汤姆叫我去.

He was angry not because we were late but because we made a noise.

他很生气不是因为我们来迟了,而是因为我们弄出了声音.

As it was raining hard,we had to be indoors. 由于雨太大,我们只好呆在家里.

Since you feel ill,you'd better not go to work. 既然你感觉不舒服,你最好不要去上班了.

（5）目的状语从句用法要点

常用的引导连词有so that,that和in order that译为：以便,为了,目的是.eg.

Please speak more slowly so that we can make full notes. 请讲慢一点,以便我们能作详细笔记.

I shall write down your address that I may not forget. 我要把你的地址记下来,以免忘记.

I sent the letter by air mail in order that it might reach him in time. 这封信我以航空信发出,以便他能及时收到.

注：目的状语从句可以用动词不定式来替换做目的状语.eg.

We work harder than usual finish it in a week. 我们比平常加倍努力工作以在一周内完成工作.

三、主句与从句时态一致的问题.

在时间状语从句和条件状语从句中,主句和从句之间的时态一致问题一般分下列两种情况：

1. 若主句是祈使句,或主句中有情态动词,或主句中谓语动词是一般将来时,那么从句用一般现在时表示一般将来时.例如：

Be careful when you cross the road. 过马路时要小心.

Put up your hand if you have any questions to ask. 如果你们有问题要问的话,请举手.

The traffic must stop when the lights are red. 红灯亮时,车辆必须停下.

2. 若主从句谓语动词都是陈述过去,那么主从句都可以用一般过去时.例如：

She could sing when she was four years old. 她四岁的时候就会唱歌.

宾语从句：

宾语从句是用来充当宾语成分的句子.其构成为"引导词+主语+谓语+其它",其语序是陈述句语序.引导宾语从句的连接词很多,多有实在意义,称为有意连词；that也可以引导宾语从句,但本身没有实在意义,称为无意连词.

1.that引导的宾语从句可以作动词、形容词等的宾语.主句中常见的谓语动词有say, know, hear, see, hope, think, believe, write, tell等.系动词加形容词afraid, worried, sure等后,也可用that引导的宾语从句.

如：I hope that he will come back soon. 我希望他能快点回来.

2.在由that引导的宾语从句中,由于连词that只起引导功能,无具体意义,不作句子成分, 因此在口语或非正式文体中常可省略,省略之后不影响原句性质和意义.

3.由that引导的宾语从句中的时态,通常分三种情况：若主句为一般现在时或一般将来时,宾语从句可根据具体情况选用时态；若主句是过去时,从句一般用相应的过去时态；若从句表示的是客观真理、名言、自然现象等,从句时态不受主句限制.

4.主句若是I/We think (believe, guess, suppose, imagine...)时,后面的宾语从句若要表示否定概念时,一般应将否定词not 转移到主句的谓语中.

如：I don't think (that) you are right. 我认为你不对.

5.含that宾语从句的复合句在变成反意疑问句时,如果主句的谓语动词为think,believe, guess, suppose, imagine等且主语是第一人称时,附加疑问部分要由从句决定；反之,附加疑问部分由主句决定.

如：I don't think that he can answer this question, can he?我认为他答不出这个问题,不是吗?

定语从句：

定语从句（Attributive Clauses）在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词.定语从句通常出现在先行词之后,由关系词（关系代词或关系副词）引出.

关系代词有：who, whom, whose, that, which等.

关系副词有：when, where, why等.

I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反.
