定语从句连接方法

❶ 定语从句该怎么用

有关定语从句的概念(1)定语从句：就是在复合句里充当定语的从句，它通常紧靠在所修饰的名词或代词后面。(2)先行词：就是被定语从句修饰的名词或代词。(3)关系词：引导定语从句的词叫关系词。关系词有关系代词who, whom, whose, which和that等;关系副词有when, where, why等。关系词不仅起连接作用，而且还代表先行词并在定语从句中担任某一句子成分，关系代词作主语、宾语、定语、表语等，关系副词作状语。如：This is the book that my father bought me yesterday. 这就是我父亲昨天帮我买的那本书。说明：句中修饰the book的that my father bought me yesterday就是定语从句;被定语从句所修饰的the book这是先行词;代表the book的关系代词that在定语从句中作bought的直接宾语。The time when he arrives is not known. 他到达的时间还不知道。说明：句中when he arrives是定语从句，被定语从句修饰的the time是先行词，关系副词when作时间状语。
■关系代词的一般用法先行词是人，在从句中作主语用who，作宾语用whom或who，作定语用whose;先行词是物，在定语从句中作主语或宾语都用which，作定语用of which或whose均可。在限制性定语从句中which, who, whom都可用that代替。关系代词作宾语时常被省略。This is the man who helped me yesterday. 这就是昨天帮助我的那个人。(作主语)The teacher (who/whom/that) you want to see is coming. 你要见的老师来了。(作see的宾语，可以省略)I met a boy whose father was a astronaut. 我认识一位男孩，他的父亲是宇航员。(作定语)Here is the coat which/that will be made to you. 这是一件做给你的衣服。(作主语)This is the factory (which/that) we visited last year.这就是我们去年参观的那家工厂。(作visited的宾语，可以省略)He has a book whose cover (=the cover of which) is very beautiful. 他有一本封面非常漂亮的书。
■关系副词的一般用法关系副词有when, where, why，在定语从句中作状语，分别表示时间、地点和原因。when的先行词通常是time, day, season, age, occasion等时间名词;where的先行词通常是place, city, town, village, house, case, situation, scenes等地点或情形名词;why的先行词只能是reason。关系副词when和where有时可用“介词+which”代替，why可用for which代替。如：There are occasions when (=on which) one must yield. 任何人都有不得不屈服的时候。Beijing is the place where (=in which) I was born.北京是我的.出生地。Is this the reason why (=for which) he refused our offer?这就是他拒绝我们帮助他的理由吗?注意：先行词虽然是时间或地点，但若在定语从句中作主语或宾语时，要用关系代词。(1)The factory where his father worked has closed. 他父亲曾工作的那家工厂关闭了。(作状语)比较：The factory which/that was built in 1978 has closed. 1978年建的那家工厂关闭了。(作主语)(2) I’ll never forget the days when we lived together. 我永远也忘不了我们一起生活的那些日子。(作状语)比较：I’ll never forget the days (that) we spent in Australia. 我永远也忘不了我们在澳大利亚度过的那些日子。(作及物动词spent的宾语)(3) The reason (why) she was ill was that she had eaten bad meat. 她生病的原因是她吃了变质的肉。(作状语，用关系副词)比较：The reason (that) he gave for his absence was obviously fabricated.他所说的缺席理由显然是编造的。(作gave的宾语，用关系代词)

❷ 定语从句的使用方法

定语从句及相关术语
1.定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。关系词常有3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。

，名词，代词，数词，分词，副词，不定式以及介词短语来担任，也可以由一个句子来担任．
定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句．
I. 限制性定语从句的特殊用法
II. 非限制性定语从句
III. 同位语从句
IV. 同位语从句和定语从句的区别

I. 限制性定语从句的特殊用法
1. way + 定语从句

way 后面跟定语从句有三种形式。

(1) way + in which + 定语从句

例如：

She was pleased with the way in which he had accepted her criticism.

(2) way + that +定语从句

例如：

They didn’t do it in the way that we do now.

(3) way + 定语从句

例如：

He didn’t speak the way I do.

2. as 引导的定语从句

(1) 在由 as 引导的定语从句中所修饰的词（先行词）前面常有 such 或 the same。

例如：

Such people as you describe are rare nowadays.

I have the same trouble as you (have).

(2) As 在定语从句中可以作主语、宾语或表语。

例如：

Let’s discuss only such questions as concern everyone of us.（作主语）

I never heard such stories as he tells.（作宾语）

I’ve never seen such a clever man as he is.（作表语）

(3) As 有时引导非限制性定语从句，可在定语从句中作主语、宾语、表语，修饰主句，常解释为正如、如同。

例如：

As is known to all, the earth moves round the sun.（作主语）

As was expected, he performed the task with success.（作主语）

As he predicted, the wind changed.（作宾语）

The meeting is very important, as indeed it is.（作表语）

II. 非限制性定语从句
1.非限制性定语从句由 who, whom, which 引导（不可用 that），还可以由 whose, when, where 等词引导。

非限制性定语从句要用逗号隔开，非限制性定语从句可以删去，整个句子的意思还是完整的，而限制性定语从句如果被删去，句子的意思不完整。

例如：

Mr Brown, who is our English teacher, lives near our school.

Yesterday I met my son’s school master, whom you saw at my home last year.

He has finished the difficult exercise, which is easy for you.

The factory is headed by a 35-year-old man, whose wife is from America.

They will fly to Qing, where they plan to stay for two weeks.

In these days, when I was a child, the city had no instry to speak of.

注意：非限制性定语从句中的关系词是不可省略的。

2.非限制性定语从句有时并非修饰名词或代词，它可以修饰整个句子。

例如：

They have invited me to visit their country, which is very kind of them.

3.in front of, at the back of, in the middle of 等短语在定语从句中的用法。

如果关系代词是作这类介词短语的宾语时，介词短语必须提前。

例如：

Yesterday afternoon we arrived at his log cabin, in front of which stood a tall

tree.

4.注意此类句子表达方式。

There are forty students in their class, thirty of whom are League members.

也可以改成

There are forty students in their class, of whom thirty are League members.

III.同位语从句

同位语从句常跟在 idea, fact, doubt, thought, belief, news, hope 等词后面，由连接代词 that（不可用 which）和连接副词 when, where, whether 等引导。

例如：

I had no idea that you were here.

The fact that he is unfit for his job is quite clear.

Then arose the question where we were to get the machine needed.

All the time she was in bitter doubt whether she was right.

IV.同位语从句和定语从句的区别

同位语从句用于名词后面，对该名词的内容作进一步说明，连接词在从句中不作成份。

定语从句用于修饰名词或代词，引导定语从句的关系代词或关系副词往往在定语从句中作一个成份。

例如：

Have you heard the news that Mr Smith will come to give a lecture on Irish Fairy Tales?

这里 that 引导的是同位语从句，不可以用 which 代替 that， 连接代词在从句中不作成份。

Have you told him the news that I told you last week?

这里 that 引导的是定语从句，可以用 which 代替 that，它在定语从句中作宾语

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。
1 关系代词引导的定语从句

关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that
这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想见的人吗？（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。（whom/that在从句中作宾语）

2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：
They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green.请递给我那本绿皮的书。

3）which, that
它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语）

2 关系副词引导的定语从句

关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。
1）when, where, why
关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：
There are occasions when (on which) one must yield.任何人都有不得不屈服的时候。
Beijing is the place where (in which) I was born.北京是我的出生地。
Is this the reason why (for which) he refused our offer?这就是他拒绝我们帮助他的理由吗？

2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：
His father died the year (that / when / in which) he was born.他父亲在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。

3 判断关系代词与关系副词

方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.

判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.

习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。

方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。
例1. Is this museum ___ you visited a few days age?
A. whereB. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. whereB. that C. on whichD. the one
答案：例1 D，例2 A

例1变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。
而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。

4 限制性和非限制性定语从句

1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month.这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。

3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。

说明：关系代词that和关系副词why不能引导非限制性定语从句。

5 介词+关系词

1）介词后面的关系词不能省略。
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 和where 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?

6 as, which 非限定性定语从句

由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.

典型例题
1）Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. whichD. he
答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。

2）The weather turned out to be very good, ___ was more than we could expect.
A. whatB. whichC. thatD. it
答案B。which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。

3）It rained hard yesterday, ____ prevented me from going to the park..
A. thatB. whichC. as D. it
答案B.
as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
(1） as 引导的定语从句可置于句首，而which不可。
(2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。
在本题中，prevent由于是行为动词，所以正确选项应为B。

As 的用法
例1. the same… as；such…as 中的as 是一种固定结构, 和……一样……。
I have got into the same trouble as he (has).
例2. as可引导非限制性从句，常带有'正如'。
As we know, smoking is harmful to one's health.
As is know, smoking is harmful to one's health.
As是关系代词。例1中的as作know的宾语；例2中，它充当从句的主语，谓语动词know要用被动式。

7 先行词和关系词二合一

1)Whoever spits in public will be punished here.
(Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school.
(what 可以用all that代替)

8 what/whatever;that/what; who/whoever

1）what = the thing which；whatever = anything
What you want has been sent here.
Whatever you want makes no difference to me.
2) who= the person that whoever= anyone who
（错）Who breaks the law will be punished.
（错）Whoever robbed the bank is not clear.
（对）Whoever breaks the law will be punished.
（对）Who robbed the bank is not clear.
3) that 和 what
当that引导定语从句时 ，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从句， 用作连接代词，作从句的具体成分，且不能省略。
I think (that) you will like the stamps.
What we need is more practice.

9 关系代词that 的用法

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, much, few, any, little等作先行词时，只用that，不用which。
c)先行词有the only, the very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。.
e)先行词既有人，又有物时。

举例：
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。

❸ 英语定语从句的连接词的选法是什么呀越细越好

很简单的，人用who,that,物用which,that.当
先行词
受到only
very
之类的副词修饰时，只能用that.
非限定性定语从句
，必须用which或者who,不能用that.

❹ 定语从句中连接词的用法

4、先行词：被定语从句修饰的名词、代词称为先行词。
关系代词引导的定语从句举例
关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1、who, whom, that
这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
(1) Is he the man who/that wants to see you? 他就是想见你的人吗？（who/that在从句中作主语）
(2) He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语）
2、Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）
(1) They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。
(2) Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。
3、 which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
(1) A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作主语）
(2) The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语）
限定性定语从句

一、关系代词（在句中作主语、宾语或定语）
1. that既可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语也可以省略。[eg：this is the book （which）you want。]
2而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置
3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括当先行词是anything, everything, nothing , none等不定代词时，或者是由every, any, all, some, no, little, few, much等修饰时等，这时的that常被省略 还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that
4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语
5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与 of which 调换,表达的意思一样。
二、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是关系副词，用来表示地点的定语从句。
2. when引导定语从句表示时间〔注〕值得一提的是，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.
I still remember the first time I met her.
Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。
3. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导
There is somebody here who wants to speak to you. 这里有人要和你说话。
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. 在踢足球的男孩们是一班的.
(2) Yesterday I helped an old man who lost his way. 昨天，我帮助了一个迷路的老人.
2. whom指人，在定语从句中充当宾语，常省略。（注：who和whom已无太大区别，基本可以通用。唯一区别是who可以做主语而whom不可以。）
(1) Mr. Liu is the person (whom) you talked with on the bus. 刘先生就是在公交车上和你聊天的那个人.
(2) Mr. Ling is just the boy whom I want to see. 凌先生恰巧就是我想见的那个男孩.
(3) The man who/whom you met just now is my friend. 你刚刚见到的那个人就是我的朋友.
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。
如果在从句中做宾语,就用whom或who.比如: He is the man whom/who I talk to. 他就是那个和我聊天的男人.
如果是在从句中作主语就只能用who.比如: He is the man who has an English book. 他就是那个有英语书的男人.
3. 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 once 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.
(4) The classroom the door of which is broken will soon be repaired.
(5) Do you like the book whose color is yellow?
(6) Do you like the book the color of which is yellow?
4.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. 足球是大多数男孩都喜欢的游戏.
(2) This is the pen (which) he bought yesterday. 这是他昨天刚买的钢笔.
5. that指人时，相当于who或者whom；指物时，相当于which。
在定语从句中做主语或者宾语，做宾语时可省略。
(5) The number of the people that/who come to visit the city each year rises one million.
(6) Where is the man that/whom I saw this morning?

关系副词引导的定语从句

1. when指时间，在定语从句中做时间状语
(1) I still remember the day when I first came to the school.
(2) The time when we got together finally came.
2. where指地点，在定语从句中做地点状语
(1) Shanghai is the city where I was born.
(2) The house where I lived ten years ago has been pulled down.
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.

PS：that也不是万能的……
关系代词that 的用法
(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, much, few, any, little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。
[编辑本段]难点分析
（一）限制性定语从句只能用that的几种情况
1、当先行词是anything, everything, nothing (something 除外), few, all, none, little, some等代词时，或者是由every, any, all, some, no, little, few, much，each等修饰时
(1) Have you taken down everything (that) Mr. Li has said?
(2) There seems to be nothing (that) seems impossible for him in the world.
(3) All that can be done has been done.
(4) There is little (that) I can do for you.
注意1：部分时候that可以省略，如部分例句将that用括号括住。
注意2：当先行词指人时，偶尔也可以用who
(4) Any man that/.who has a sense of ty won’t do such a thing.
2、当先行词被序数词修饰
The first place that they visited in London was the Big Ben.

其实就如一楼的所说，定语从句的语法并不算难，有个固定的格式，只要弄明白前后句之间的联系和意思就好填空了。提供一下本人的答案，不过还是希望LZ可以理解记忆最好~~

❻ 定语从句的结构是什么

定语从句结构为：定语从句=先行词+关系词+从句

1、先行词指被定语从句修饰的名词、代词。一般先行词出现在定语从句的前面。

2、关系词作用：连接作用，连接主句和定语从句。指代先行词。在定语从句中担当成分。

3、定语用来限定、修饰名词或代词，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、分词短语）汉语中常用“……的”表示。

从句在主句中充当定语成分。被修饰的词叫先行词。定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后。

定语 从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。

(6)定语从句连接方法扩展阅读：

关系代词所代替的先行词是人或物的名词或代词，并在从句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。

which在定语从句中指物，可作主语或及物动词或介词的宾语，作宾语时可省略；that在定语从句中既可指人又可指物。

在定语从句中作主语、宾语和表语，作宾语时可省略，指人时，相当于who或whom，指物时，相当于which，作介词宾语时，介词不可提到that前，当介词提前时，需要用which或whom来代替。

关系代词：在句中作主语、宾语或定语。

1、that既可代表事物也可代表人，“which”代表事物；它们在从句中作主语或宾语，作宾语可省略“that”在从句中作宾语时常可省略关系词，“which”在从句省略。[eg：This is the book （which）you want.]

2、如果which在从句中作“不及物动词+介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前面，但有的则放在它前面的位置。

❼ 定语从句的用法

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。
18.1 关系代词引导的定语从句

关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that
这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想见的人吗？（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。（whom/that在从句中作宾语）

2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：
They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。

3）which, that
它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语）

18.2 关系副词引导的定语从句

关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。
1）when, where, why
关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。
Beijing is the place where (in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗？

2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：
His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。

18.3 判断关系代词与关系副词

方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.

判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.

习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。

方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D，例2 A

例1变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。
而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。

18.4 限制性和非限制性定语从句

1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。

3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。

说明：关系代词that和关系副词why不能引导非限制性定语从句。

18.5 介词+关系词

1）介词后面的关系词不能省略。
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 和where 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?
18.6 as, which 非限定性定语从句

由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.

典型例题
1）Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。

2）The weather turned out to be very good, ___ was more than we could expect.
A. what B. which C. that D. it
答案B。which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。

3）It rained hard yesterday, ____ prevented me from going to the park..
A. that B. which C. as D. it
答案B.
as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
(1） as 引导的定语从句可置于句首，而which不可。
(2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。
在本题中，prevent由于是行为动词，所以正确选项应为B。

As 的用法
例1. the same… as；such…as 中的as 是一种固定结构, 和……一样……。
I have got into the same trouble as he (has).
例2. as可引导非限制性从句，常带有'正如'。
As we know, smoking is harmful to one's health.
As is know, smoking is harmful to one's health.
As是关系代词。例1中的as作know的宾语；例2中，它充当从句的主语，谓语动词know要用被动式。
18.7 先行词和关系词二合一

1)Whoever spits in public will be punished here.
(Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school.
(what 可以用all that代替)

18.8 what/whatever;that/what; who/whoever

1）what = the thing which；whatever = anything
What you want has been sent here.
Whatever you want makes no difference to me.
2) who= the person that whoever= anyone who
（错）Who breaks the law will be punished.
（错）Whoever robbed the bank is not clear.
（对）Whoever breaks the law will be punished.
（对）Who robbed the bank is not clear.
3) that 和 what
当that引导定语从句时 ，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从 句， 用作连接代词，作从句的具体成分，且不能省略。
I think (that) you will like the stamps.
What we need is more practice.
18.9 关系代词that 的用法

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, much, few, any, little等作先行词时，只用that，不用which。
c) 先行词有the only, the very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。.
e) 先行词既有人，又有物时。

举例：
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。

这些全在这了 够了吧？

❽ 定语从句的结构

从句结构
先行词
指被定语从句修饰的名词、代词。
一般先行词出现在定语从句的前面。[1]
关联词
关联词常有2个作用：
①连接作用，引导定语从句。
②代替先行词，在定语从句中担当一个成分。
注：关系代词有主语、宾语、定语之分。一般who做主语或其宾格形式的whom做宾语，whose作为定语（whom，whose不可省略）。关系代词在从句中作主语，宾语，定语等，关系副词在从句中作地点状语（where）时间状语（when），原因状语（why）。[1]
定语
定语用来限定、修饰名词或代词，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、动名词表示的）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、从句作定语时则放在所修饰的词之后，作后置定语。
被定语从句修饰的名词、代词称为先行词。如“the
girl”，“the
book”
如:She
is
the
girl
who
likes
singing.
她就是那个爱唱歌的女孩。
这就是一个定语从句。[1]

❾ 定语从句连词用法

简单点说呢,除了前面有介词后面必须得用which,that都是可以用的,就是说,除了以上情况,能用which的地方就能用that.that既可以指人又可以指物.而which就不行,它只可以指代物,然后如果先行词前面有某些限定词如last啊什么的就只能用that不能用which.
who跟whom的区别就是后者只能在从句中充当宾语而前者主语宾语都行..whose就可以理解成是形容词性物主代词,意“为...的”.
这类题型基本都是以选择题的形式出现,可以用排除法,

❿ 用定语从句连接下列句子

这是将两个简单句变为定语从句的基本方法。
方法： 1 找到 两个句子中的共同的词。并以主要说的句子为主句。
第一句为例 my sisiter broke the digital camera. I bought it last week.
共同的 词 为 the digital cameral 和 it , 第一句是主句 ，因为第二句是说明camera的来源或介绍的，解释说明的 。
2 这个词 主句保留 从句中的 用 引导词 代替 ：人用 who或whom代替 物用 which 代替
my sisiter broke the digital camera. I bought （which） last week.

3 就近原则：将引导词提前紧跟先行词（就是两句话中相同的这个词）-
my sisiter broke the digital camera （which） I bought last week. 这句中 which 在从句中做宾语 所以也可以省略 。

希望你能自己变一下 后面的。
注意：1 找哪个是主句是看主要要表达的意思。主句不一样，强调的重点不一样（第2题见下面的解析 ）
2 先行词的选择 that 既能代替人 又能代替物 但 多是在 主句中那个词是 the/ my/ most 等词修饰的时候
这三个叫关系代词 这个词做主语或宾语
还有几个叫关系副词 这个词 做状语 一般就是地点 时间和原因 where when why 没有what
比如 常说的一句话 you are the most beautiful girl I have ever seen.
就是 you are the most beautiful girl 和 I have ever seen the girl。

第2题 The policeman is Bill's father. He helped Grandma cross the street.

你可以是 The policeman who is Bill's father helped Grandma cross the street.
意思强调的是 比尔的爸爸是个警察，他扶老奶奶过马路。 “扶老奶奶过马路” 是重点

The policeman who helped Grandma cross the street is Bill's father.
意思强调的是 扶老奶奶过马路的那个警察是比尔的爸爸。 "警察是比尔的爸爸"是重点

3 The book (which) he has taken away is very interesting.

4 The boy who brought us the letter yesterday is my brother.
或者
The boy who is my brother brought us the letter yesterday.

5 The hospital where i was born is not far from here.
或者
I was born a hosipital which is not far from here.

注意 同是先行词 hosipital 但是 关系词一个是用where，在从句中做地点状语 另一个用which 做从句的 主语

6 I will never forget the day when i join the party.
或 I joined the party on the day (which ) I will never forget. 同5 的道理
