在定语从句中which和where有什么区别?
There are many works of art in the museum ( ) we will visit tomorrow.A.where B.who C.which 我怎么A C觉得都行呢?

在定语从句中which和where有什么区别?There are many works of art in the museum ( ) we will visit tomorrow.A.where B.who C.which 我怎么A C觉得都行呢?
应该选C. The museum在这里表示物,作visit的宾语部分,所以用which.
定语从句及相关术语
1.定语从句：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,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.

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.
[编辑本段]介词和关系代词
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 ,where和why 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?
This is the reason why he came late.
This is the reason for which he came late.
介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时
从句常由介词+关系代词引导
(1) The school (that/which) he once studied in is very famous.
= The school in which he once studied is very famous.
(2) Tomorrow I will bring here a magazine (that/which) you asked for.
= Tomorrow I will bring here a magazine for which you asked.
(3) We’ll go to hear the famous singer (whom/that/who) we have often talked about.
= We’ll go to hear the famous singer about whom we have often talked.
注意：
1. 含有介词的动词短语一般不拆开使用,如：look for, look after, take care of等
T This is the watch which/that I am looking for. (T＝正确)
F This is the watch for which I am looking. (F＝错误)
2. 若介词放在关系代词前,关系代词指人时用whom,不可用who或者that；指物时用which,不能用that；关系代词是所有格时用whose
(1) The man with whom you talked is my friend. (T)
The man with that you talked is my friend. (F)
(2) The plane in which we flew to Canada is very comfortable. (T)
The plane in that we flew in to Canada is very comfortable. (F)
3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词
(1) He loved his parents deeply, both of whom are very kind to him.
(2) In the basket there are quite many apples, some of which have gone bad.
(3) There are forty students in our class in all, most of whom are from big cities.
关系代词
关系代词（一般情况下）that 可用who ,whom 和which在从句做主语,谓动词的宾语,但是不能做介词的宾语.
which指物,在从句中作主语,谓语或宾语；
who在从句中作主语；
whom在从句中宾语；
where在从句中修饰表地点的名词,做地点状语；
when在从句中通常修饰表时间的名词,做时间状语；
why在从句中做原因状语,先行词通常是"reason"
有时why也可用for+which代替.
例：A doctor is a person who looks after people's health.

定语从句修饰先行词
判断介词和关系代词
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.不及物动词后面无宾语,就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语,则要求用关系代词.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 ago?
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,is后应跟表语,只有the one可以,而后面的you visited a few days ago则做one的定语从句.
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) .
[编辑本段]先行词和关系词
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)
但这两句句子已经不是定语从句了,是名词性从句.因为定语从句一定要有先行词,而名词性从句没有.将“Whoever”、“what”分别用“Anyone who”、“all that”代替后,才是定语从句,先行词分别是“Anyone”、“all”.
as,which引导的非限制性定语从句 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 known, 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.
一、“as / which” 特殊定语从句的先行成分
1. 形容词或形容词短语作先行成分, 具有形容词意义的介词短语也可以充当先行成分,如：
My grandmother’s house was always of great importance to me, as my own is.
在一定的语言环境里,有些名词可以具有形容词的性质.这些名词主要是那些表示人的身份、职业、状态的名词.值得一提的是,在这些具有形容词性质的名词之后,引导定语从句的关系代词不能用who / whom.
2. 动词短语先行成分.
这种动词短语既可是限定形式也可是非限定形式.如果是动态动词短语,它们在从句中就一般有限定或非限定形式的替代动词do和as / which一起代替.do可以出现,也可以不出现,但不能用其它动词代替.
3. 句子作先行成分.
这句子可以是整个主句也可以只是主句中的一个从句.有时是连续几个句子,有时甚至可以是一个完整的故事.
二、“as/which”特殊定语从句在句中的位置
由于先行成分的构成成分不同,“as/which”特殊定语从句在句中的位置有以下几种情况：
1. 形容词做先行成分时：形容词或形容词短语（含具有形容词性质的名词）作先行成分,“as / which”特殊定语从句置于先行成分之后.
2. 动词短语作先行成分时：动词短语作先行成分时,“as / which”特殊定语从句置于先行成分之后.但是,当从句中含有表示主观意志的插入成分时,“as”特殊定语从句可以移至句子之首.
3. 句子作先行成分时：“as”特殊定语从句的位置较灵活,可以置于先行成分之前、之中或之后.但如果先行成分是直接引语,“as”特殊定语从句多在先行成分之前.如果先行成分是否定句,“as”特殊定语从句与否定词的相对位置不同可以使它产生不同的意义.由于“as”特殊定语从句具有这一特点,所以有时它的位置不能随便移动.在非正式的文体里,“which”特殊定语从句可以出现在先行成分之中.
三、“as/which”特殊定语从句的语义功能
一般说来,as与which的语义功能相同,可以相互替换.但先行成分为句子时,它们的语义功能则有差异.
1. 表示结果
表示结果的特殊定语从句与其先行成分之间存在着一定的因果关系,从句中往往使用有结果意义的词,如动词result, make, enable, cause和形容词interesting, surprising, delightful, disgraceful等.
2. 表示评注
表示评注的特殊定语从句对其先行成分所述事实的正确性有肯定的倾向,它通常与那些表示客观事实,普遍真理或某种习性的先行成分连用；从句中则常用一些表示“合乎自然规律”、“众所周知”或“经常发生”等意义的词语,如natural, known to all, usual等.
3. 有无状语意义
“as”特殊定语从句具有状语意义（主要是方式状语意义）,而“which”特殊定语从句则无状语意义.“as”特殊定语从句的状语意义要求它在语义上与其先行成分的语义保持一致,“which”特殊定语从句则不受这种限制.
四、关系代词as与which的句法功能
1. as / which 在特殊定语从句中作主语.
as作主语时,谓语动词常为连系动词（主要是be, seem）,主语补语为usual、 a rule、 a matter of fact等时,系动词be习惯经常省略.行为动词作“as”特殊定语从句的谓语时一般用于被动语态（其中助动词be常略）,不及物的行为动词在“as”特殊定语从句中作谓语的极少,常见的有happen一词.如：
Freddie, as might be expected, was attending the conference.
Which作主语时,谓语动词不限,主语被动皆可,只是谓语动词为被动语态时助动词be省略.
2. as和which都可以在特殊定语从句中宾语.
3. as和 which在特殊定语从句中作补语.如：
We thought him a gentleman, as/which he could never be.
“as”特殊定语从句中可以主谓倒装,“which”从句中则不能主谓倒装.
如果先行成分不是主语补语或宾语补语,关系代词用which而不用as.如：
He talked like a native, which/as he hardly was.
4. which在特殊从定语句中作定语.
which可以在特殊定语从句中作定语,修饰fact, matter, thing 等名词.这些名词代表先行成分表达的意义,有时将其略去句义仍然完整.as不能作定语.如：
I was told to go not by train but bus, which advice I followed.
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 duty 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.
3、当先行词被形容词最高级修饰时
This is the best film that I have seen.
4、当形容词被the very, the only,the same,the last 修饰时
(1) This is the very good 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
Can you remember the scientist and his theory that we have learned?
7.当关系代词在定语从句中做表语
The village is no longer the one that it used to be 10 years ago.

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.例如：
This is the house in which I lived two years ago. 这是我两年前住过的房子.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗?
Do you remember the day when you joined our club?
