它们都有什么区别?怎么用?
定语从句由关系代词who、whom、whose、which、what、as和关系副词where、when、why等引导,但须记住:
1.what不能引导定语从句.
2.关系词的分析须考虑它在定语从句中的成分。
一.指人的关系代词有who、whose、whom、that. 试分析:
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. (=The man who/whom that my father shook hands with just now is our headmaster.)注:
A. 指人时有时只用who不宜用that。
1.先行词为one、ones或anyone
(1)The comrade I want to learn from is the one who studies hard and works hard.
(2)Anyone who breaks the law should be punished.
2.先行词为these时
These who are going to Beijing are the best students of our school.
3.在there be 开头的句子中
There is a student who wants to see you.
4.一个句子中带有两个定语从句,其中一个定语从句的关系代词是that,另一个宜用who,以免重复。
The student that won the first prize is the monitor who works hards.
5.在非限制性定语从句中
A。I met a friend of mine in the street, who had just come from Japan.
B.主句以who开头的句子中,只用that,不用who。
二.指物的关系代词有which、whose(=of which)、that. 试分析:
1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
注:
A. 介词如果位于作为其宾语的关系代词之前时,只能用whom、 which不能用who或that.
(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短语动词中的介词不可与动词拆开,在定语从句中其介词不可前置,只能放在其动词之后。
Is this the book which she is looking for?
The old man who/whom they are waiting for is Professor Li.
The child who/whom she is looking after is Wang Ping’s son.
C. 指物时,下列情况下只能用that ,不宜用which。
(1)先行词为不定代词,如All、much、anything、everything、nothing、something、none、the one等。
We are willing to do anything that is good to the people.
I have told them all (that) I know.
All that can be done has been done.
(2)先行词是序数词或被序数词、修饰时。
The first book that I read last night was an English novel.
(3)先行词是形容词最高级或被最高级修饰时。
This is one of the most interesting films that I have ever seen.
This is the best that can be done now.
(4)如果有两个或两个以上分别表示人和物的先行词时(先行词既有人又有物),定语从句的关系代词用which和who都不合适,只能用that。
We know nothing about the doctors and the hospitals that you are talking about.
There are sheep and men that can be seen on the hill.
(5)如果先行词被the only、the very、the last、the same、any、 few 、little、no、 all 、one of、 just修饰时。
This is the only book that can be lent to you.
(6)当主句是以which开头的特殊问句时,关系代词只用that。
Which is the dictionary that he used yesterday ?
D.只物时,下列情况下只能用which,不宜用that。
(1)关系代词放在介词之后
This is the factory in which we once worked.
(2)非限制性定语从句中
This is the book, which is written by Lu Xun.
(3)that,Those作主语时
Those which are on the desk are English books.
E.先行词前有such、the same、 as时, 关系代词用as,不用that, 但the same…as…表示同样的, the same…that…表示同一的
He knows as many people as are present at the meeting.
Such people as you refer to are rare nowadays.
三.比较When/which、where /which、why.
which I still never forget.
This is the day when I joined the party.
which he spent reading the books.
where I found the book.
which makes machines.
This is the place which we once visited.
which I will never forget.
which I am looking for.
限制性定语从句与非限制性定语从句的区别:
限制性定语从句
非限制性定语从句
All the students who study hard have passed.学习努力的学生都考试及格了。(只有努力的及格了,不努力的没及格。) All the students ,who study hard have passed.所有的学生都及格了,他们学习努力。(没有人不及格,这些学生都很努力。)
从句是先行词不可缺少的定语(如去掉,主句意思就不完整或不正确。) 从句是对先行词的附加说明(如去掉,主句意思仍清楚,不受影响。) 与主句关系密切,不用逗号 与主句关系不十分密切,用逗号与主句隔开译为汉语时,从句译在先行词前,与先行词用“的”连接 译为汉语时,从句放在主句后面关系代词that可以代替who、whom(指人)、which(指物) 关系代词不用that,只用who、whom(指人)、which(指物) 关系代词代替宾语时可以省略 关系代词不能省略关系代词as和which
先研究下面两个例句:
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出来,这头象像条蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考试不及格,这使得他父亲很生气。
这两个例句中,as和which所代表的都是整个主句所表示的内容。但有两点不同之处:
1. 在形式上as引导的非限制性定语从句可位于主句的后面,也可位于主句的前面;而which引导的非限制性定语从句只能位于主句的后面,不能位于主句的前面。
2. 在意义上,as引导的定语从句和主句的关系一般为一致关系,常译为“正如……”,“就像……”,而which引导的定语从句和主句的关系是因果关系,或which引导的定语从句是对主句的评论。因此,在意思通顺的情况下,which可代替as,而as许多时候不能代替which,如句○2。再如:
1.He was late again, as / which we had expected. =As we had expected, he was late again. 正如我们所料,他又迟到了。/他又迟到了这是我们早就料到的。
2. The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期没有打扫了,因此整条街很脏。(不用as)
3.The young man cheated his friend of much money, which was disgraceful. 那年轻人诈骗了他朋友许多钱财,这是不光彩的。(不 用as)
4.He takes exercise everyday, which has done a lot of good to his health. 他每天运动,这对他的身体很有好处。(不用as)
5.As has already been pointed out, English is rather difficult for a foreigner. 正如已经指出的那样,英语对于初学者说,是相当难学的。在such…as…、the same…as…、 as…、 as many…/much as…等结构中,as不能用which代替。如:
1.Such books as this are too difficult for beginners. 这样的书对于初学的人来说是太难了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大楼里。
3.He knows as many people as are present at the meeting. 他认识所有到会的人。
4.That day we all got up early as usual. 那天我们和平时一样,都起得很早。
“One of the +复数名词”后面定语从句中谓语单复数情况
这一结构后面的定语从句的谓语动词通常用复数形式,跟定语从句所靠近的那个复数名词在数上保持一致。如:
1. That is one of the books that are required for study at school.
2. This is one of the most wonderful novels that have been published since 1990.
3. She is one of the few persons who know Spanish .
4. This is one of the most famous plays that were written in the thirties,
如果one of +复数名词这一结构前面带有the only、the very之类的限定语,后面定语从句的谓语动词则要用单数形式,这是因为定语从句在意义上修饰的是而不是那个复数名词。如:
1.He is the only one of the teachers who knows French in our school.( 修饰the only one)
He is one of the teachers who know French in our school.( 修饰the teachers)
2.This is the only one of the rooms that is free now. (修饰the only one)
This is one of the rooms that are free now. (修饰rooms)
as与which引导的定语从句
两者均可引导非限制性定语从句,有时可以互换,但下列情况多用as。
1. 关系代词引导的定语从句居句首时。 As we all know, the earth is round.
2. 当与such或the same连用时,一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 当从句和主句语义一致时,用as,反之则用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在从句中作主语时,后面常接行为动词的被动语态,如be known,be said,be reported等,如从句中行为动词是主动语态,一般要用which作主语。
She has been late again, as was expected.
Tom has made great progress, which made us happy.
1.what不能引导定语从句.
2.关系词的分析须考虑它在定语从句中的成分。
一.指人的关系代词有who、whose、whom、that. 试分析:
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. (=The man who/whom that my father shook hands with just now is our headmaster.)注:
A. 指人时有时只用who不宜用that。

3.在there be 开头的句子中
There is a student who wants to see you.
4.一个句子中带有两个定语从句,其中一个定语从句的关系代词是that,另一个宜用who,以免重复。
The student that won the first prize is the monitor who works hards.
5.在非限制性定语从句中
A。I met a friend of mine in the street, who had just come from Japan.
B.主句以who开头的句子中,只用that,不用who。

1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
注:
A. 介词如果位于作为其宾语的关系代词之前时,只能用whom、 which不能用who或that.

1。宾语从句一般是由that,what···引导的句子作宾语,起修饰谓语的作用。要放在所修饰谓语之后。由that引导时,that在从句中作主语一定不能省略,如果作从句的宾语是可以省略的。
2.表语从句一般由that和关系代词如what···引导的,有时也由关系副词引导如when,where···表语从句要放在系动词之后,起表语的作用,用来修饰主语。
3.状语从句可表示时间,地点,原因,结果,方式,让步···时间状语从句可由when,while和一些副词如after,before,till···来引导。地点状语从句通常由where引导。原因状语从句一般由because(of),as,since···来引导。说白了,状语从句的引导词就是由有相应含义的关系副词和词组等词引导。还有就是,状语从句一般放在句尾。
4.定语从句是用一个句子来修饰先行词(先行词可以是人,物,全句)。定语从句的引导词为that,关系代词(what,which)和关系副词(when,where,how,why)。一般情况下,that可以通用。当定语从句修饰全句时,从句中的谓语用单数。定语从句一般紧跟先行词,但有时候定语从句和先行词之间也会有其他的句子成分,这时就要仔细辨析了,分清定语从句修饰的谁就好办了。
5.同位语从句和定语从句很相像,引导词和位置是一样的,所以很容易被他们迷惑。但是同位语从句是用来说明先行词的内容的,所以一般情况下,先行词是news,fact,thought,reply等抽象名词。通常同位语从句的引导词是that,而that在从句中不做任何成分,只起连接作用。而定语从句是用来修饰先行词的,相当于形容词的作用。定语从句中的that在从句中做主语或宾语,做宾语时可以省略。
最后送你一句话,要想学好语法,还是需要多练习的,多分析句子中的结构。

宾语从句:在句子中起宾语作用的从句叫做宾语从句。宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。
表语从句:表语从句就是用一个句子作为表语。说明主语是什么或者怎么样,由名词、形容词或相当于名词或形容词的词或短语充当,和连系动词一起构成谓语。
状语从句:状语从句 (Adverbial Clause) 状语从句指句子用作状语时,起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导,也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。
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。
同位语从句:在复合句中充当同位语的名词性从句称为同位语从句。
等到初三总复习的时候,老师会详细解释的
如果还没到初三,即使不太懂也没事的

从句在句子中做宾语,起到宾语的作用,就是宾语从句。比如Nobody knew whether he could pass the exam. whether he could pass the exam就是knew的宾语
其它的也是这样,看宾语在句子中的作用。
