❶ 英语中从句的语法大全
英语中六大从句用法总结
1.主语从句
1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.
3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.
2.宾语从句
1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。
He didn't think that the money was well spent.
3.表语从句
表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.
The reason why so many people died there is that there were not enough food supplies.
It looks as if successful international cultural communication will make the world smaller.
4.同位语从句
同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。
She finally made the decision that she would join the fashion show.
I had no idea how many books I could borrow at a time.
The news came that their team had won the championship.
5.定语从句
定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。
*限制性定语从句
限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)关系代词的省略
在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。
This is one of those things with which we have to put up.
This is one of those things (which\that) we have to put up with.
3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
5.定语从句
*非限制性定语从句
非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.
*“介词+which\whom\whose”引导的定语从句
“介词+which\whom\whose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中，代替先行词是人或物的名词。as引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。
These are not such problems as can be easily solved.(as代替先行词problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)
6.状语从句
*时间状语从句
引导时间状语从句的从属连词和词组有：
1）when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。
As soon as I sent an e-mail message,I received positive responses.
The moment he heard the good news,he jumped with joy.
*地点状语从句
引导地点状语从句的连词是where,wherever.

*原因、结果和目的状语从句
1）引导原因状语从句的从属连词有：because,as,since,now(that),seeing that,considering that,in that等。
Considering that he is a freshman,we must say he is doing well.
2)引导结果状语从句的连词有：so...that,such...that
,so that,that,so等。

We got up early this morning so that we could catch the first bus to the railway station.
*条件和让步状语从句
1）引导条件状语从句的连词和词组有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+谓语”。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中，谓语动词常用虚拟语气，表示与事实相反。
The young man made the experiment just as the teacher had taught him.
Everything went on as usual as if nothing had happened.
❷ 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=ring/ 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.
❸ 英语语法中的从句
大致有下面几种（以下是我个人总结的，仅供参考）：
一、名词性从句
其中又包括主语从句、同位语从句、宾语从句、表语从句
What I have is only a piece of bread.(What引导的主语从句)
News spread in the village that he came back.(that引导的同位语从句)
I think that you are right.(that引导的宾语从句)
What I appreciate is that you are brave.(that引导的标语从句)
二、形容词性从句
也就是定语从句
The mountain is beautiful from the top of which we can see our school.(which 引导的定语从句)
三、状语从句
主要有时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语从句、让步状语从句、比较状语从句、程度状语从句、方式状语从句、结果状语从句
I will call you as soon as I arrive in Beijing. （as soon as引导的时间状语从句）
You should have put the book where you found it.(where引导的地点状语从句)
I hate you because you hurt me.(because 引导的原因状语从句)

She passed the examination though she had not studied very hard.(though引导的让步状语从句)
She finds it easier to read than to write．（than引导的比较状语从句）
❹ 英语语法中什么是从句，宾语从句壮语从句和其他从句呢解释清楚点谢谢。通俗点也没关系能懂就行了，最...
答：从句与主句的关系，好比是子公司和总公司的关系。一个公司有经理和工作人员。一个句子有主语和谓语两部分组成。子公司是总公司的一个组成部分。从句是主句中的一个句子成分。按功能分，有名词性从句（包括主语从句、宾语从句、表语从句和同位语从句）、形容词性从句（即定语从句）和副词性从句（即状语从句），按句子成分分有主、宾、表、同、定、状语从句
例：That the earth goes around the sun is know to us all. 主语从句。
We all know that the earth goes around the sun. 宾语从句。
What we all know is that the earth goes around the sun. 主语从句， 表语从句。
The fact that the earth goes aroung the sun is known to us all. 同位语从句。
This is the best film I have even seen. 定语从句。
Where there is a river, there is a big city. 状语从句。
❺ 英语语法中从句有几种，要详细的。
英语中六大从句用法总结
1.主语从句
1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.
3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.
2.宾语从句
1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。
He didn't think that the money was well spent.
3.表语从句
表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.
The reason why so many people died there is that there were not enough food supplies.
It looks as if successful international cultural communication will make the world smaller.
4.同位语从句
同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。
She finally made the decision that she would join the fashion show.
I had no idea how many books I could borrow at a time.
The news came that their team had won the championship.
5.定语从句
定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。
*限制性定语从句
限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)关系代词的省略
在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。
This is one of those things with which we have to put up.
This is one of those things (which\that) we have to put up with.
3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
5.定语从句
*非限制性定语从句
非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.
*“介词+which\whom\whose”引导的定语从句
“介词+which\whom\whose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中，代替先行词是人或物的名词。as引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。
These are not such problems as can be easily solved.(as代替先行词problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)
6.状语从句
*时间状语从句
引导时间状语从句的从属连词和词组有：
1）when,whenever,while,as,after,before,since,till,until,once等。

*地点状语从句

*条件和让步状语从句
1）引导条件状语从句的连词和词组有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+谓语”。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中，谓语动词常用虚拟语气，表示与事实相反。

❽ 高中的英语语法，从句部分的讲解
高三英语语法重点难点点拨 <<陈老师课堂>>
高中英语状语从句讲解
一．原因从句
1. 由as／because／since 引导的原因从句：
We camped there as／because／since it was too dark to go on．我们在那里露宿是因为天太黑，不能再继续往前走了。
As／Because／Since it was too dark to go on，we camped there．因为天太黑不能再继续往前走，我们就在那儿露宿了。
2. in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand．既然你在这儿，就帮我个忙吧。
As／Since／Seeing that Tom knows French，he’d better do the talking．既然汤姆懂法语，最好让他来谈。
二．结果从句
结果状语从句——引导结果状语从句的连词有：so that, so…that, such that, such…that, that等。当从句前面有逗号时，so that中that可省略，如：
It was dark, so (that) we could see nothing in front of us.
“So + 形容词 / 副词 + that”是引导结果状语从句的常用结构，如：
He talked so loud that he annoyed the speaker. He was so brilliant that he made a lot of inventions.
“such (a) + 形容词 + 名词 + that”与“so…that”的意义相同，如：
It was such a hot day that people could not go out. He painted such beautiful pictures that the visitors were lost in admiration.
such／so…that引导的结果从句
A such是形容词，用于形容词+名词结构之前：
They had such a fierce dog that no one dared to go near their house．他们有一条如此凶猛的狗，以致没人敢靠近他们家。
He spoke for such a long time that people began to fall asleep．他说了这么长时间，以致在座的人都犯困了。
B so是副词，用于副词和不带名词的形容词之前：
The snow fell so fast that our footsteps were soon covered up．雪下得这么快，以致我们的脚印很快就被雪盖住了。
His speech went on for so long that people began to fall asleep．他的讲话这么长，以致在座的人都开始犯困了。
Their dog was so fierce that no one dared come near it．他们的狗太凶猛了，所以没人敢靠近它。
such不能用于much和many之前，so可用于后跟名词的much和many之前：
There was so much st that we couldn’t see what was happening．灰尘太大了，使得我们看不清发生了什么事。
So many people complained that they took the programme off．抱怨的人太多，所以他们取消了那个节目。
C 注意：such＋a＋形容词＋名词可由so＋形容词＋a＋名词来代替，所以such a good man可由so good a man来代替。这只能在名词前面有a／an的情况下使用。
热点之一：含有否定意义的副词放在句首引起的部分倒装
此类副词有：not，never，seldom，hardly，rarely，little等。例如：
Not a single word did he say at the meeting．（在会上，他什么也没说。）
热点之二：含有否定意义的连接词置于句首引起的部分倒装
此类连接词有：not only．．．but also，neither．．．nor．．．，no sooner．．．than，scarcely．．．when，hardly．．．when等。请看例句：
No sooner had she gone out than the telephone rang．（她一出门电话就响了。）
热点之三：搞清so（nor ，neither）＋助动词＋主语与so（nor ，neither）＋主语＋助动词之间的区别
前者表示重复前句部分的内容，译为“也是如此”。而后者表示对前句内容的进一步肯定或证实，译为“确实如此”。例如：
Lily can't answer the question．Neither can I．莉莉不能回答这问题。我也不能。
Tom was late for school yesterday．So he was. 汤姆昨天上学迟到。他确实如此。
热点之四：省略if的虚拟条件句以had ／were ／should开头引起的部分倒装
这是虚拟语气中比较特殊的一种，其实质就是省略if后引起的变化。如：
Had he worked harder，he would have got through the exams．（要是他努力学习的话，他是会通过考试的。）
热点之五：not until置于句首引起后面句子的部分倒装
not until意为“直到……才……”，位于句首时引起后面的主句倒装。如：
Not until the teacher came did he finish his homework．老师来了他才完成作业。
热点之六：only短语置于句首引起的部分倒装
only放在句首，修饰副词、介词短语或状语从句，常引起后面句子部分倒装。如：
Only in this way can you learn English well．只有通过这种方式，你才能把英语学好。
让步从句
它们由下列词来引导：although，though，even though，even if，no matter，however有时也可以使用whatever。as也可以，但是只限于形容词＋as＋be结构。
Although／Though／Even though／Even if you don’t like him you can still be polite．尽管／即使／纵然／即使你不喜欢他，你仍可有礼貌一些。
No matter what you do，don’t touch this switch．无论怎样，都别碰这个按钮。
However rich people are，they always seem anxious to make more money．无论人们多么富有，他们似乎总还渴望赚到更多的钱。

Whatever you do，don’t tell him that I told you this．无论如何，别跟他说这件事是我告诉你的。
Patient as he was，he had no intention of waiting for three hours．哪怕他再有耐心，也不打算等上三个小时。
比较从句

You work harder than he does／than him／than I did at your age．你比他干得卖劲／我在你这个年龄时干得卖劲。
时间从句
A 时间从句由下列表示时间的连词来引导：
after immediately till／until no sooner…than when as soon as since whenever before the sooner while hardly…when the minute the moment
B 时间从句中不用将来时态。
1 如将下列将来时态放入时间从句中，须将它变为一般时态。
You’ll be back soon．I’ll stay till then．= I’ll stay till you get back．你会很快回来，我一直等到那时。
C since从句
since从句后面常跟完成时态
They’ve moved house twice since they got married．／Since they got married，they’ve moved house twice．他们结婚后已搬了两次家。

It’s ages since I sailed／have sailed a boat．我未驾驶帆船已有好多年了。
I haven’t sailed a boat since I left college．自从我大学毕业后就没再驾驶帆船了。
D after从句
after从句之后常跟完成时态：
After／When he had rung off I remembered… 等他把电话挂断后，我才想起……
After／When you’ve finished with it，hang it up．你用完了之后，请把它挂起来。
E hardly／scarcely… when，no sooner… than
The performance had hardly begun when the lights went out．= Hardly had the performance begun when the lights went out．演出刚开始就停电了。
这里可以用scarcely代替hardly，但不常见。

He no sooner earns any money than he spends it．= Immediately he earns any money he spends it．他钱一挣到手，就花光了。
注意the sooner…the sooner的用法：
The sooner we start，the sooner we’ll be there．我们动身得越早，到那儿就越早。
