谁能讲解下英语中的各种从句?

谁能详细的讲解以下 英语中的定语从句~

定语从句其实很简单。定语从句，顾名思义，就是用一个从句做定语来修饰前面的词语，但这个从句（也包括除定语从句以外所有的从句）是不能独立成句的。(定语从句可以是各种时态，但在这里为了方便，举例时只用几种基本时态。)定语从句永远置于被修饰者后面，而且有引导词。引导词在从句中充当两种成分：一是主语，此时引导词不可省略；二是宾语，此时引导词可省略。引导词主要有以下几种：
一 that,可以在一切句子中使用，即指代一切人、物。如：

(1)你刚才画的那幅画很漂亮。
The picture (that) you drew is very beautiful.
(此时that充当drew的宾语，可省略。)
(2)刚才与你说话的那人是谁？
Who is the person that talked with you?
(此时that充当talked的主语，不可省略。)

二 which，只能指代物。如：
(1)你看见的那条狗是我的。
The dog (which) you saw is mine.
(此时which充当saw的宾语，可以省略。)
(2)攻击你的那条狗不是他的。
The dog which attacked you isn't his.
(此时which充当attacked的主语，不可省略。)
另外，上部分中的(1)句中的that可以用which代替，同样可以省略。

三 who，只能用于修饰人，可在从句中充当主语及宾语，但充当宾语时一般用宾格whom，whom可省略。如：
(1)和你儿子玩的那个小女孩是谁的女儿？
Whose daughter is the girl who is playing with your son?
(此时who充当is playing的主语，不可省略。)
(2)你要遇见的那个人就是你的老师。
The man (who/whom) you will see is your teacher.
(此时who/whom充当see的宾语，可省略。)
另外，第一部分中的(2)句中的that可用who代替，同样不可省略。

四 whose，有“…的”的意思，可用于修饰人、物，一般不可省略。如：
(1)这就是爸爸是个警察的那个小男孩。
This is the boy whose father is a policeman.
(2)房主是个商人的那所房子很大。
The house whose owner is a bussinessman is very large.

定语从句若要转换句型，如变一般疑问句、特殊疑问句(例如划线部分提问的题型)、反意疑问句时，如果你不明白，可以先将引导词和从句一同去掉不看，先把剩下的简单句按照基本方法转换，再在完成的句子里找到需要修饰的部分，把从句原封不动安在后面就可以了。同样，若疑问句要求回答时也可以用这种方法。

定语从句概要： （这是有关定语从句的精要介绍，涵盖了有关定语从句的各个方面，供参考：） 引导定语从句的关联词包括关系代词和关系副词。关系代词有that, which, whose, who, whom, as；关系副词有when, where, why。关系代词和关系副词在定语从句中都充当一定的句法成份。关系代词在从句中充当动词的宾语时一般可以省略。 关系代词的选用比较复杂，受下列条件的制约： (1) 要看先行词是指人还是指物， (2) 要看关系代词在从句中句法功能， (3) 要看定语从句是限定性的还是非限定性的。 在定语从句中充当的成分 ↓ 用于限定性或非限定性从句 只用于限定性从句 指人 指物 指人或指物 主语 who which that 宾语 whom which that 谓语 whose whose (of which) That 只能用在限定性定语从句中，而who, whom, which, which 既可用于限定性定语从句中，也可用于非限定性定语从句。 I know that he is a man who means what he says. I know that he is a man that means what he says. 【我知道他是一个守信用的人。】 The gentleman whom she met addressed her with courtesy. The gentleman that she met addressed her with courtesy. 【她遇到的那位先生很有礼貌地向她打了招呼。】 The gentleman she met addressed her with courtesy.（在从句中充当动词宾语的关系代词，可以省略。） The watch which was lost has been found. The watch that was lost has been found. 【丢了的表找到了。】 Here is the material which you need. (注：现代美语中不允许这样用) Here is the material that you need. Here is the material you need. 【你要的材料在这儿了。】 You are the only one whose advice he might listen to. 他也就是听你的话吧。 关系副词的选用相对来说比较简单，如果先行词是表示时间的名词，如time, day 等，则用when, 如先行词为表示地点的名词，如place, house, area 等等，则选用where。如果先行词为reason 则选用why I will never forget the mountain village where I spent my childhood. I will never forget the mountain village in which I spent my childhood. 我永远也不会忘记我度过童年的那个小山村。 I don’t know the reason why he did that. I don’t know the reason for which he did that. 【我不知道他为什么这么做。】 当先行词是all, something, nothing 等不定代词时，或者先行词的前面有first, last, only, few, much, some, any, no 等词修饰时，或者先行词的前面有最高级修饰时，一般只用that 而不用which 来引导定语从句： I have explained everything that I can to you. I have explained everything I can to you. 【我已经尽一切可能把事情向你解释得一清二楚。】 具体详情请上百度百科查询。从句—请点击此连接就可查询各种从句的具体解释 http://baike.baidu.com/view/138129.htm

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。

英语中几大从句的用法总结（转自英语吧）2007年02月09日 星期五 22:31
今天起为大家介绍一下英语中几大从句的用法以及其相关内容，如果总结地不够详尽的，还请各位朋友补充说明，谢谢。

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.

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.

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.
Wherever she went,she took her little daughter with her.

*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。
Mickey Mouse is so attractive that the children are reluctant to leave.
3)引导目的状语从句的连词有：so that,in order that,for fear that,lest等，从句常使用may,might,can,could,would等情态动词。
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.
