（一）定义
1)在复合句中（一个句子的某一成分由句子承当），修饰某一名词或代词从句叫定语从句或形容词从句；在句中起定语的作用.
2)被定语从句修饰的词叫做先行词antecedent
1) The man who lives next to us is a policeman.[
先行词 关系代词 定语从句
2) You must do everything that I do.
先行词 关系代词 定语从句
(二)：关系代词的作用;
1.连接主句和从句。
2.代表被修饰的先行词。
3.在定语从句做一个句子成分。

先行词 关系代词 定语从句
(三)：定语从句中有 关系代词 who, whom, whose, which, that, as.
关系副词 when, where, why 等引导定语从句。

限制性定语从句 非限制性定语从句
从句与先行词的关系 从句是先行词不可缺少的定语，如果省去，主句的意思就会不完整或不明确。 从句只是对先行词的附加说明，如果省去,主句的意思仍然清楚或完整

关系代词一般不可省
修饰 从句只修饰一个名词或代词 可以修饰一个名词或代词也可修饰整个主句
翻译 定语从句译在被修饰词的前面 定语从句通常被译成另一个独立的句子
限制性 非限制性
形式上 无逗号 有逗号
内容上 先行词不是唯一的 先行词是唯一的，定语从句可有可无。
关系词 可用that ,why.作宾语可以省略 不可用that ,why。关系词一律不省。
先行词 名词或代词 名词或代词，也可以使整个句子
汉语翻译 译作定语 译成并列句
1．二者差异比较
限制定语从句紧跟先行词，同先行词之间一般不加逗号，仅修饰先行词，可以由关系代词．关系副词或that来引导。非限制性定语从句仅作补充或说明，用逗号与主句隔开，既可修饰先行词，又可修饰整个主句，不可用that引导。
He has a brother who is a physicist.
He has a brother, who is a physicist. (只有一个)
He returned all the books which are written in English.
He returned all the books, which are written in English.
I will wear no clothes which will be out of ordinary.
I will wear no clothes, which will be out of ordinary.

I’m sure I know the person who served me.
Tom, who served us, is the owner of the restaurant.
A student who studies hard will make good progress.
The student, who lives far from school, is the leader of their football match.
（六） 关系代词that和 which的区别
<1>． 只能用that的情况
(1) 如果先行词是all, much, anything, something, nothing, everything, little, none ，few.等不定代词，关系代词一般只用that，不用which。例如：
All the people that are present burst into tears.
Everything that we saw was interesting.
I’m interested in everything that I don’t know.
All that is needed is a supply of oil.
(2) 如果先等词被 all ,little none any, only, few, much, no, some, very等词修饰，关系代词常用that,不用which.
例如：I read all the books that you gave to me.
This is the only money that I have in my pocket.
All the money that was collected was given to the Hope Project.
(3) 如果先行词被序数词、形容词最高级修饰或者先行词是最高级时，关系代词常用that,不用which。
This is the first book that was written in English.
This is the last factory that I visited.
This is the best film that I have ever seen.
This is the funniest thing that I ever heard.
(4) 如果先等词被the only ,the very , the same ,the last修饰，关系代词常用that,不用which.
This is the only book that I really like.
He was the only person in the office that was invited to the ball.
(5) 先行词有两个，一个指人，一个指物，关系代词应该用that。而不用who, which.
例如： The boy and the dog that are in the picture are very lovely.
He talked about the teachers and schools that he had visited.
(6)who ,which开头的特殊疑问句中，关系代词用that.
Who is the person that is standing there?
Which of us that knows English doesn’t know this?
which of the novel do you like best?
(7) 关系代词作表语时，关系代词用that.
It took us many years to make the city that it is today.
He is not the man that he used to be.
China isn’t the country it used to be.
(8) 先行词是奇数词或是序数词时，关系代词用that .
Yesterday I caught two fish. Now you can see the two that are still alive in the basin of water.
(9) 当主句 “ there be “开头时，关系代词要用that 引导的定语从句修饰该句型的主语。
There are four desks in the middle of the office that are used for the teachers.
(10) 当先行词是 “ to be “ 后面的表语时关系代词用that .
This is the dictionary that was bought in the bookstore yesterday.
<2>．只能用which的情况
1) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。如：
There are about seven million people taking part in the election, most of whom、are well educated.
Bei jing , which is china’s capital, is rich in culture.
2)those/that +名词后的定语从句用which引导。不能用关系代词that。
That pen which he took is mine.
A shop should keep those goods which sells well.
3) 介词后只用which
This is the room in which he lived.
I don’t know the man to whom you talked.
The chair on which he is sitting is made of wood.
(4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中，which可以作主语，也可以作宾语或表语， 不用that..例如：
He succeeded in the competition, which made his parents very happy.
(5)先行词是that时，关系代词要用which.
What’s that which flashed in the sky just now?
(6) 关系代词后面有插入语时，益用关系代词 which.
Here is the English grammar book which, as I have told you, will help to improve your English.
<3>．只用who, whom.而不用that的情况
(1) 如果先行词是anyone, anybody, everyone, everybody, someone, somebody, those, ones等时，关系代词应该用 who 或whom，不用 which .that。例如：
Is there anyone here who will go with you?
People all like those who have good manners.
（2） 当先行词是指人的集合名词时，如果作这个名词着眼于集体的整体，关系代词用which;若是指集体中的各个成员，则用who。
Mr. Smith came to visit my family, who were watching TV then.
Our class, which is a very good one, was praised again at the meeting.
(3)当先行词有较长的 后置定语或者在被分割的定语从句中，宜用关系代词 who
Pro. Wang is coming soon who will give us a talk on how to learn English.
(4) 当先行词用-body 或-one 构成的复合不定代词时，关系代词用who
We’d better not believe in anyone who we don’t know.
(5) 当先行词是一个限定性的表示人的特定名词时，常用who
The aunt/uncle who came to see us last week is my brother’s sister.
（七）．“介词＋关系代词“是一个普遍使用的结构
(1)“介词＋关系代词“可以引导限制性定语从句，也可以引导非限制性定语从句。“介词＋关系代词“结构中的介词可以是 in, on, about, from, for, with, to at, of, without 等，关系代词只可用whom或 which,不可用 that 。其中whom代表人，which代表物
Who is the comrade with whom you shook hands?
He works in a factory, in front of which there is a river
Give me the book the cover of which is red (the cover of which=whose cover)
He is the man whose father is a teacher.=He is the man the father of whom is a teacher.
This is the neighborhood from whom I borrowed the bicycle.
(2) from where为“介词＋关系副词“结构，但也可以引导定语从句（不常用）。例如：
We stood at the top of the hill, from where we can see the town..
（3）***关系代词前的介词如何确定？
A.依据定语从句中动词的某种习惯搭配
Mr. Smith bought a new house on which he spent all his money.
B.依据先行词的某种习惯搭配确定
There was no way in which it could be bought back to the earth. ( in this way)
C.根据所表达的意思确定
The gas with which doctors can save the patients is called oxygen.
The gas without which we can not live is called oxygen.
(4)***注意关系代词的位置
介词在关系代词前时，只能用which 和whom不能用that 代替，也不可省略；介词在句尾时，关系代词可which ,that ,whom, who,都行，而且还可以省略。
This is the drawer in which I put my letters.
= This is the drawer (which/that )I put my letters in.
Have you seen the pen with which I wrote letters this morning?
= Have you seen the pen (which/that) I wrote letters with this morning?
所以一个句子有时有多种用法
如：那就是他工作的大学
This is the college at which he works.
This is the college that/which he works at.
This is the college where he works.
但像listen to, look at, depend on, pay attention to, take care of等固定短语动词，在定语从句中一般不宜将介词与动词分开。例如：
This is the boy whom she has taken care of.
This is the book which /that I am looking for.
This is the girl I have been looking for the whole afternoon.
（八） whose 引导从句的意义
1）指人=of whom 表示所修饰的“某（些）人的用做所修饰的先行词的所有格。
A child whose parents are dead is called an orphan.
2) 指物=of which 表所修饰的“某物的“
I live in the room whose window faces south.
I live in the room, the window of which faces south
( whose +从句 可以用“of which +从句”代替)
（九）As 与which 是有区别的
A) 相同之处： 都可以用来引导非限制性定语从句，指代前面的主句所表达的内容。which 可做宾语或表语
He failed once more in the match, which was a great pity.
He succeeded in the composition, which made his parents very happy.
B) 区别：
1）as引导的非限制性定语从句位置较灵活，可以位于主句前面．中间或后面，一般用逗号与主句隔开，但which所引导的非限制性定语从句只能放在主句之后。例如：
1) As we all know, Galileo’s theory of falling objects is right.
= Galileo’s theory of falling objects, as we all know, is right
= Galileo’s theory of falling objects is right, as we all know.
2) He was thrown into prison, which got round throughout our village
3) As is expected, the England team won the football match.
4) The earth runs around the sun, as is known by everyone.
5) He was late again, which made me unhappy
6) As you know, he is good at English.
2.） as有“如” 、“正如”、“像”、“正像”的含义，which 没有。后面的谓语动词多是see, know, expect, say, mention, report等。
Bob did an excellent job, as we had expected.
Our team won the game, which made us happy.
As is known to all, Taiwan is part of China.
We are facing the same problems as we did years ago.
We are facing the problems which we faced years ago.
We hope to get such a tool as he is using.
We hope to get the tool which he is using.
3.) as 在引导限制性定语从句多与such 或the same连用，可以代替先行词是人或物的名词。
the same…as such….as
This is the same story as he told me.
I hope to get such a book as he is using
4).as 也可单独使用，引导非限制性定语从句，作用相当于which。可代表一个句子。例如：
The elephant’s nose is like a snake, as anybody can see.
5).as做主语时， 其后必跟系动词，而which 无此限制
The meeting was put off, as was what we wanted.
He was murdered, as seemed true.
6)as引导从句时，从句语义必须和主句一致
She was married again, which was unexpected
She was married again, as was unexpected 7
7）the same …as 与the same ..that 的区别： 前者修饰的是原物同样的
而后者修饰的就是先行词
This is the same watch as I lost.这和我丢的那一只手表是一样的。
This is the dame watch that I lost.着就是我丢的那一只手表。
（十）什么时候that 可以省略？
1) 引导同位语从句，主语从句，表语从句不能省略，且不做成分。
The name “ whitewater ”comes from the fact that the water in these streams and rivers looks white when it moves quickly.
It’s known to all that light travels in straight lines. ( that 置后可一省略)
The reason for his absence was that he was ill. ( 有时可省，一般不省)
2）宾语从句中可以省略
I don’t think (that) you are right.
3）that 只有在定语从句中做成分，可做主、宾、表语。
（十一）关系代词做主语，谓语动词的单复数取决于先行词而不是关系代词。
I want to see the film that is on show.
The students who don’t study hard will not pas the exam.
(十二)one of the… 与the one of the … 做先行词时谓语不一致。
Li Bai is one of the greatest poets that have lived in China.
Li Bai is the one of the greatest poets that has lived in China.
This is one of the books that I have been written in Chinese.
This is the only one of the books that has been written in Chinese.
He is one of the boys who are willing to do it.
He is the only one of the boys who is willing to do it.
（十三）．关系副词引导的定语从句
1．关系副词也可以引导定语从句
关系副词在从句中分别表示时间．地点或原因。关系副词when在从句中充当时间状语，where 充当地点状语，why充当原因状语。
1)when 表示时间, 充当时间状语 when=on/ in/ of /at…+which
I still remember the day when I join the party
I will never forget the day when I first came to Beijing.
但注意：
1.当先行词是表地点：place ,room, mountain, airport等时间：time, day, year, month, week,等原因：reason 等名词时,并且分别在句中做地点、时间、原因状语时，应用where ,when ,why引导。但是如果如果表示时间地点原因的名词不做状语，而是做主语，宾语，或者表语时，必须用关系代词that /which来引导而不是用where等。
I still remember the day that we spent together。
May 1 is the day that I will never forget。
The Yangtze Gorges is a beautiful place (that /which) people all over the world look forward to visiting.
长江三峡是个美丽的地方，全世界的人都渴望来参观。
The moment (that /which) I turned around, she had left and disappeared in the crowd.
Is this the reason that he gave us for being late?
This is the factory that we visited
That is the house that he lived in..
The place that we had been to was far.
The shop that /which we saw is beautiful.
2.当先行词为 by the time ,any time , the way, every time, the first time ,the last time 时，关系词不用when而用that.或省略
This is the last time that I shall give you a lesson.
The first time I saw him was in 1980
By the time he was 14 he had learned advanced mathematics
但如果time前无修饰语,关系词用that when 均可
I will never forgot the time when (that) we met for the first time.
3. 当先行词为way 时，关系词用in which ,that, 或省略.
This is the way that/ in which / 不加 he smiles.
但注意：
4.why 表示原因（现行词只有一个 reason），做原因状语。 Why= for which
That is the reason why he was late.
（十四）学生容易出现的问题。
1. 在定语从句中多加了宾语，如：
Some of the boys I invited them didn’t come.
Some of the boys I invited didn’t come.
Is this the horse you drew it yesterday?
Is this the horse you drew yesterday?
2. 把定语从句的动词的单复数弄错。
Those who has finished may leave the classroom now.
They key opens the room is missing.
Those who have finished may leave the classroom now.
This is one of the rivers in China which flows northward.
This is one of the rivers in China which flows northward.
3. 省略了定语从句中做主语的关系代词。
Children eat a lot of sugar often get bad teeth.
Children who eat a lot of sugar often get bad teeth.
They key opens the room is missing.
They key which/that opens the room is missing.
4. 定语从句中加了多余的关系副词或者是介词。
The house where he lives in needs repairing.
The house where he lives needs repairing.
The house which/that he lives in needs repairing.
This is the time at when he’s more likely to be in.
This is the time when he’s more likely to be in.
This is the time at which he’s more likely to be in.
（十五）代有插入语的定语从句who 与whom 的选用。
担主语成分时用who ,担 宾格成分时用whom
方法：要区分是定语从句中的插入语还是主谓结构。
Jason is a man who (I believed) is honest.(去掉仍成立)
Jason is a man whom I believe to be honest.
做宾语
The girl who we supposed was drowned came back.
The girl who we supposed to be drowned came back.
（十六）什么时候宜用非限制性定语从句
1） 当先行词是专有名词时，通常用非限制性定语从句，它本身就具有特殊性，无需在加限定。
Shenzhen, which is in South China, is developing rapidly.
My house, which I bought last year, has got a garden .
Mr. Smith bought a new house on which he spent all his money.
2) 当先行词是具有某一特征的人或者物中的一个，但跟非限制从句时则表示唯一的一个，compare:
Her room has a window which faces south.
Her room has a window, which faces south.
I have a brother who is working in Beijing.
I have a brother, who is working in Beijing.
3.当先行词表示类属意义，即表示某类动物，事物或人时，其后所跟的定语从句一般是非限制性的。
A sleep is a useful animal, whose wool has many uses.
Football, which is a very interesting game, is now played all over the world.
