定语从句中什么时候用WHICH什么时候用THAT引导

定语从句中什么时候用that什么时候用who.which~

1、that的用法
that的先行词是人或物,在定语从句中作主语、宾语或表语。
主要特点有：
①that在定语从句中作主语时不省略,作宾语时可以省略；
②that不引导非限制性定语从句；
③that前不加介词
例子Theforeigners that visited our school yesterday are from Canada.
昨天参观我们学校的外国人来自加拿大。(that代替人作主语)
只能用that引导定语从句的情况:
①先行词被序数词或形容词最高级修饰；
②先行词是不定代词all, the one, everything等；
③先行词被 any , the only , the last等修饰；
④先行词既指人又指物时。
例子Alice is the only person ( that ) I can trustin the office.
爱丽丝是办公室里我唯一信任的人。(先行词被the only修饰只用that)
2、which的用法
先行词是物,在定语从句中作主主语或宾语。
主要特点：
①which在定语从句中作主语时不能省略,作宾语时可以省略,引导非限制性定语从句时不能省略；
②which的前面可以有介词;
③which的先行词可以是前面数个的的句子,意为”这使…….;这一点……”。
例子 A computeris a machine which can do many things for us.
电脑是一种可以为我们做许多事情的机器。( which作主语)
3、who的用法
who的先行词是人。who在定语从句中作主语、宾语或表语。
例子 I like theboy who gets along well with his classmates
我喜欢那个与他的同学相处得好的男孩。
先行词为one、ones、anyone或 those时,或双重定语从句中一个定语从句的关系代词是that，另一个指人的关系代词词用who。

扩展资料
在定语从句中which和that用法区别：在定语从句中，which 和that 在指代事物时，一般可以互换使用，但并非在任何情况下都是这样，几种宜用that,而不宜用which 的情况如下：
1、先行词为不定代词,all,much,something,everything,anything,nothing,none,the one等。
2、先行词被only, any, few, little, no, just, very, one of等词修饰时。
3、先行词是序数词时或被序数词修饰时。
4、先行词是最高级或被最高级修饰时。
5、先行词既有人又有物,用which和who都不适合,这时宜用that。
6、被修饰词为数词时。
7、如果有两个从句,其中一个关系代词已用which ,另一个关系代词宜用that,以避免语言的单调或重复。
8、疑问词是who或which,关系代词宜用that,以避免重复。
9、主句是There be 结构,修饰其主句的定语从句宜用that 作关系代词。
10、被修饰成分为表语时,或者关系代词本身是定语从句的表语时,该关系代词宜用that。
定语从句中宜用which而不宜用that 的情况：
1、当关系代词的前面有介词时。
2、在非限制性定语从句中。
3、在一个句子中有两个定语从句,其中一个定语从句的关系代词用了that, 另一个宜用which。
4、当关系代词后面带有插入语时。
5、先行词本身是that, 宜用which。
6、先行词是those+复数名词。

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,有时也可以修饰部分或整个句子.
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,as .
关系副词有：when, where, why ,how .
关系代词和关系副词放在先行词和定语从句之间,起连接作用,同时又可做定语从句的一个成分.当关系代词做宾语时可以省略.
定语从句中的谓语动词必须在人称上和数量上和先行词保持一致.
定语从句分为限制性定语从句和非限制性定语从句.
1 、关系代词引导的定语从句
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?（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.（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. Please pass me the book whose (of which) cover is green.
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.（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. (which / that在句中作宾语)
关系代词that和which 都可以指物,that 和Who 都可以指人,其用法区别：
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.
c)多用who 的情况
①关系代词在从句中做主语
A friend who helps you in time of need is a real friend .
②先行词为those , people 时
Those who were either fools or unfit for their offices could not see the cloth .
③先行词为all, anyone , ones , one 指人时
One who doesn’t work hard will never succeed in his work .
④在There be句型中
There is a stranger who wants to see you .
⑤在被分隔的定语从句中
A new teacher will come tomorrow who will teach you German .
⑥在有两个定语从句的句子中,其一用who,其二用that,但若先行词后接两个以上的并列定语从句时,后一个必须重复前一个关系代词.
The student who was praised at the meeting is the monitor that is very modest and studies very hard .
There is a teacher who is always ready to help others and who enjoys what he does .
2) 只能用that作为定语从句的关系代词的情况
a) 在不定代词,如：anything, nothing, everything, all, much, few, any, little等作先行词时,只用that,不用which.
All that is needed is a supply of oil.
Finally, the thief handed everything that he had stolen to the police.
b) 先行词有the only, the very, the just修饰时,只用that.
He is the very man that helped the girl out of the water .
c) 先行词为序数词(the last)、数词、形容词最高级时,只用that..
The first English book that I read was “The Prince and the Pauper” by Mark Twin .
d) 先行词既有人,又有物时.
He talked about the teachers and schools that he visited .
e)当主句是以who 或which 开始的特殊疑问句时,用that 以避免重复.
Who is the person that is standing at the gate .
f)关系代词在从句中做表语
He is not the man that he used to be .
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、方式或理由的名词,在从句中作状语.
1)when, where, why,how
关系副词when, where, why,how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.
Beijing is the place where (in which) I was born.
Is this the reason why (for which) he refused our offer?
I’m surprised the way how (by which) he works out the problem .
注意：
①在非限制性定语从句中,"介词+ which"结构不能代替关系副词.
如：They set up a state for their own , where they would be free to keep Negroes as slaves .
②含有介词短语的动词一般不能拆开,介词仍放在动词后面.
Is this the book which (that) she was looking for ?
3、名词/数词/代词 /形容词最高级 + 介词 + 关系代词引导定语从句
She has written a book , the name of which I have forgotten .
There are fifty-five students in our class , all of whom are working hard .
There are five continents in the world , the largest of which is Asia .
4、 as, which 引导非限定性定语从句的差别：
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.
as可引导非限制性从句,常带有'正如'的意思.
As is know, smoking is harmful to one's health.
用法区别：
(1) as 引导的定语从句可置于句首,而which不可.
As we all know , he never smokes .
(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..
(3)非限定性定语从句中出现expect , think , suppose 等表示猜测、想象、预料等时.
She succeeded in her doing the research work , as we expected .
(4)As 的用法 the same… as；such…as 中的as 是一种固定结构, 和……一样…….
I should like to use the same tool as is used here .
We should have such a dictionary as he is using .

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) 。

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。

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?

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。

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)

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.

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。

五．限制性定语从句和非限制性定语从句
限制性定语从句 非限制性定语从句
形式上 不用逗号和主句隔开 用逗号和主句隔开
意义上 是先行词不可缺少的定语，不能删除 是对先行词的补充说明，删除后意思仍完整
译法上 翻译成先行词的定语，“…的…” 通常翻译成主句的并列句
关系词的使用上 A．做宾语时可省略 B。可用that
C．可用who代替whom A．不可省 B。不用that
C。不用who代替whom
限制性定语从句举例：
(1) The teacher told me that Tom was the only person that I could depend on.
(2) China is a country which has a long history.
非限制性定语从句举例：
(1) His mother, who loves him very much, is strict with him.

要注意区分以下几个句子的不同
(1) His brother who is now a doctor always encourages him to go to college.
他那当医生的哥哥常鼓励他要考上大学。（他还有其他的哥哥）
(2) His brother, who is now a doctor, always encourages him to go to college.
他的哥哥是当医生的，常鼓励他要考上大学。（他只有一个哥哥）
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：当先行词指人时，偶尔也可以用who
(4) Any man that/.who has a sense of duty won’t do such a thing.
2. 当先行词被序数词修饰
(1) The first place that they visited in London was the Big Ben.
3. 当先行词被形容词最高级修饰时
(1) This is the best film that I have seen.
4. 当形容词被the very, the only 修饰时
(1) This is the very dictionary that I want to buy,
(2) After the fire in his house, the old car is the only thing that he owned.
当先行词指人时，偶尔也可以用who
(3) Wang Hua is the only person in our school who will attend the meeting/
5. 当先行词前面有who, which等疑问代词时
(1) Who is the man that is standing there?
(2) Which is the T-shirt that fits me most?
6. 当先行词既有人，也有动物或者物体时
(1) Can you remember the scientist and his theory that we have learned?
（二）关系代词as和which引导的定语从句
as和which引导非限制性定语从句，有相同之处也有不同之处。具体情况是：
1．As和which都可以在定语从句中做主语或者宾语，代表前面整个句子。
(1) He married her, as/which was natural.
(2) He was honest, as/which we can see.
2. as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思
(1) As is known to all, China is a developing country.
(2) He is from the south, as we can see from his accent.
(3) John, as you know, is a famous writer.
(4) He has been to Paris more than several times, which I don’t believe.
注意：当主句和从句存在逻辑上的因果关系时，常用which
(5) Tom was always late for school, which made his teacher angry.
3. 当先行次受such, the same修饰时，常用as
(1) I have never heard such a story as he tells.
(2) He is not such a fool as he looks.
(3) This is the same book as I lost last week.
注意：当先行次由the same修饰时，偶尔也用that引导定语从句，但是和由as所引导的定语从句意思不同
(4) She wore the same dress that she wore at Mary’s wedding. 她穿着她在MARY婚礼上穿过的一条裙子。
(5) She wore the same dress as her young sister wore. 她穿着和她妹妹所穿的一样的裙子。

（三）以the way为先行词的定语从句通常由in which, that引导，而且通常可以省略。
(1) The way in which/ that/./ he answered the question was surprising.

(四) but有时也可以做关系词引导定语从句
(1) There are very few but understand his idea. ( but= who don’t )

(五) 区分定语从句和同位语从句
1．定语从句修饰先行词，它和先行词是修饰关系；同位语从句说明先行词的具体内容，是补充说明的关系
(1) The plane that has just taken off is for London. 定语从句
(2) The fact that he has been dead is clear. 同位于从句
2．定语从句由关系代词或者关系副词引导，关系词在句中充当成分，有时可以省略；同位语从句主要由that引导，在句中一般不做成分；句子也可以由when, where, how, why, whether, what等词引导，充当成分
(1) The news he told me is true.
(2) The news that he has just died is true.
(3) The problem that we are facing now is how we can collect so much money. 定语
(4) The problem how we can collect so much money is difficult to solve.
3. 同位语从句和先行词一般可以用be动词发展成一个完整的句子，而定语从句不可以
(1) The idea that we could ask the teacher for advice is wonderful. 同位语
(2) The idea was that we could ask the teacher for advice.
(3) The fact that the earth moves around the earth is known to all.
(4) The fact is that the earth moves around the earth.

下面的笔记请楼主参考:

定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以及行为方式状语从句。名词从句包括主语从句，宾语从句，表语从句和同位语从句及there be句型。

一、 限定性定语从句

1. that即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在从句中作宾语则不能省略。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

2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢

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all, anything, much等，这时的that常被省略

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. where是关系副词，用来表示地点的定语从句

6. 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 arrive in London, we will have stayed there for two weeks.

I still remember the first time I met her.

Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.

7. 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

8. 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

二、非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立

1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分

2. 在引导限定性定语从句时，that有时相当于in which, at which, for which或at which

Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。

I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐，而他恰恰与我相反。

We arrived the day that(on which) they left. 刚好我们到的那天他们走了。
