从句
which、that 是关系代词，它在从句中代替先行词the building,
同时担任从句中的主语，也起连词的作用，把两个简单句连接 起来。
❖ 关系代词的使用取决于先行词，它们的关系非常密切，因为关系代词在
定语从句中代替主句中的先行词，所以它在一般情况下都跟在先行词之后， 而且它的 人称、数必须和先行词一致。
He knew the teacher (that) we met yesterday. 4.whose 是代词的所有格形式, 它既可以代人也可以代物。 I saw a woman . Her bag was stolen .
I saw a woman whose bag was stolen. Please show me the book . Its cover is red.

(完整版)定语从句语法详解
定语从句语法专题（Attributive Clauses）教案一. 定语从句的概述:1.定语从句：在复合句中，修饰某一名词或代词的从句叫定语从句。
在句中做定语，被修饰的名词或代词，叫做先行词。
从句通常放在先行词之后，由关系词（关系代词或关系副词）引导。
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。
eg She is the girl（who got the first prize.）girl先行词who充当从句主语, 从句做定语修饰girlThis is the boy who broke the window.这就是打破窗子的孩子。
the boy是先行词, who broke the window是限制性定语从句, 明确指出theboy是打破窗子的那个孩子,who 在从句中充当主语That is the house where he lived ten years ago.He is the man who/that lives next door.He is the man who I want to see.先行词关系词定语从句复合句: 是由一个主句和一个或一个以上的从句构成的句子, 复合句中的主句和从句都具有完整的的主语和谓语, 主句是复合句的主体, 可以独立存在, 从句需要有一个连词引导, 是修饰说明主句的, 不能独立存在, 根据在句中的不同作用, 从句可以分为三类: 定语从句, 名词性从句, 状语从句。
二. 引导定语从句的关系词有两大类:1.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: that, who, whom, whose, which, as（主, 宾, 定）关系副词: when, where, why.（状语）2.关系词的作用:（1）引导定语从句, 在先行词和定语从句之间起连接作用；（2）代替先行词在句中充当成分。

高中英语定语从句语法讲解(推荐)
高中英语定语从句语法讲解【概念】定语从句,也称为关系从句或形容词性从句,由关系代词或关系副词引导,用来限制,描绘或说明主句中的某一个名词或代词(有时也可以说明整个主句或主句中的一部分),即句子作定语.定语从句所修饰的对象被称为先行词.定语从句按其作用可分为限制性定语从句和非限制性定语从句.关系代词和关系副词的作用有:①连接作用:引导从句并同时连接主句和从句②替代作用:在从句中替代它前面的先行词③作成分:在从句中充当句子成分.如:主语(who,that,which);宾语(who,whom,which,that);表语(that,as);定语(whose,...of whom/which);时间状语(when),地点状语(where)和原因状语(why).说明:关系代词在从句中宾语时可省略,作其他成分时一般不可省略.(一)关系代词的用法1.关系词用法分类关系词例词所修饰的先行词在从句中所作的成分省略情况关系代词who 人主语,宾语,表语作宾语时可省略whom 人宾语可省略which 物主语,宾语,表语作宾语时可省略that 人或物主语,宾语,表语作宾语时可省略as 人,物或主语,宾语,表语不可省略事whose 人或物定语不可省略关系副词when 时间名词时间状语不可省略where 地点名词地点状语不可省略why 原因名词原因状语不可省略2.关系代词that和which的用法⑴限制性定语从句中,必须用关系代词that的情况:①当先行词是不定代词all,much,little,something,everything,anything,nothing,none等时.Do you have anything that you want to say for yourself?You should hand in all that you have.②当先行词被the only,the very,any,few,little,no,all等词修饰时.This is the very person that I'm waiting for.The only thing that we can do is to give you some advice.③当先行词是形容词最高级或先行词的前面有形容词最高级修饰时.This is the best way that has been used against pollution.This is the most interesting film that I've ever seen.④当先行词是序数词或它前面有序数词修饰时.This train is the last that will go to Suzhou.What is the first American film that you have seen?⑤当先行词既有人又有物时.Do you know the things and persons that they are talking about?⑵当先行词指物时,定语从句中关系代词必须用which的情况:①在非限制性定语从句中,只用which,不用that.Helen was much kinder to her youngest son than to the others,which,of course,made the others envy him.②当定语从句中的介词提前时,只用which,不用that.This is the school i n which I once studied.3.关系代词who/that,whom和whose的用法.当先行词指人: ①在定语从句中作主语时,用who/that,不可省略②在定语从句中作宾语时,用whom/who/that,可以省略③在定语从句中作定语时,用whose,不可省略She is the girl who/that lives next door.(先行词在定语从句中作主语)That's the girl(whom/who/that)I teach.(先行词在定语从句中作宾语)This is the scientist w hose achievements are well known.(先行词在定语从句中作定语)This is the house w hose w indow broke last night.=This is the house,the window o f which broke last night.=This is the house,o f which the window broke last night.4."介词+关系代词"引导的定语从句⑴当介词放在关系代词的前面时,关系代词常用which或whom,关系代词不能省略.Is this the house in which Shakespeare was born?He paid the boy ＄10 for washing ten windows,most o f which hadn't been cleaned for at least a year. In the dark street,there wasn't a single person to whom she could turn for help.⑵在限制性定语从句中,当介词位于定语从句的末尾时,可用that/which(指物),that/whom/who(指人)作介词的宾语,而且作介词宾语的关系代词可以省略.thatThis is the hero who we are proud o f.whom(可省略)thatThis is the pen which I wrote the letter with.(可省略)⑶"介词+which/whom+不定式"结构The beggar has no money with which to buy food.=The beggar has no money to buy food with.=The beggar has no money that he can buy food with.5.关系代词as引导的定语从句关系代词as既可以引导限制性定语从句,也可以引导非限制性定语从句,as在从句中作主语,宾语或表语.as引导限制性定语从句时常用于下列句式:such+名词+as...像....一样的,像....之类的⑴the same+名词+as...和....一样的其中关系代词as在从句中担当主语,宾语或表语.We have found s uch materials as are used in their factory.(as作主语)These houses were sold at such a low price as people expected.(as作宾语)He is not the same man as he was.(as作表语)⑵...such as..such为代词,意为"这样的人或物",as引导定语从句并在从句中担当成分,定语从句修饰先行词such. This book is not such as I expect.(as作宾语)6.关系代词as与which引导非限制性定语从句时的区别as引导的非限制性定语从句,既可在主句前,又可在主句后,有时还可插入主句中,而which引导的非限制性定语从句只能置于主句之后.相同的是两者都可替代整个主句的内容.The weather turned out to be very good,which was more than we could expert.As is known to everybody,the moon travels round the earth once every month.=The moon travels round the earth once every month,as/which is known to everybody.(二)关系副词的用法1.当关系词在定语从句中作状语时,要用关系副词.其中when=表时间的介词(in,at,on,during)+which;where=表地点的介词(in,at,on,under)+which;why=表原因的介词(for)+which.I still remember the day when I first came to Beijing.(when=on which)Can you tell me the office where he works?(where=in which)Do you know the reason w hy he is absent?(why=for which)2.有时先行词为抽象名词situation,stage,point等,表示模糊化的地点,可用where引导定语从句. The accident has reached a point where both their parents are to be called in.(三)定语从句用法的其他要点1.定语从句中的谓语动词与先行词保持一致当引导定语从句的关系代词在从句中作主语时,定语从句中的谓语动词在人称,数方面应该与先行词保持一致.⑴one of+复数名词+关系代词+动词复数形式.Titanic is one of the most wonderful movies that have been produced in Hollywood.⑵the only one of+复数名词+关系代词+动词单数形式Titanic is the only one of these wonderful movies that has been produced in Hollywood.⑶当关系代词as与which引导非限制性定语从句,修饰主句内容时,若as与which作主语,则从句的谓语动词用单数形式.Great changes have taken place in China,as is known to all.2.注意way和time后接定语从句的情况⑴当先行词是way(意为"方式,方法"),定语从句中缺宾语时,引导定语从句的关系词有下列三种形式:thatThe way which he explained to us was quite simple.不填而当定语从句中缺状语时,引导定语从句的关系词有以下三种形式:。

高一级英语定语从句讲解
高一级英语定语从句讲解一、定语从句1．定语从句三步：第一找出先行词；第二看先行词在定语从句中的语法功能（做主语、宾语或状语）；第三选择合适的关联词。
2．定语从句在选择关联词that 与which时，常常容易出错，所以应记住什么时候只能用that，什么时候只能用which.（1）．只能用that 的情况归纳4种：即先得词被序数词最高级修饰过；先行词为all 、everything、nothing等不定代词；先行词同时是人和物并列时；最后先行词分别被the only 、the very the same、the last 修饰。
请看下列四组例句，注意其先行词：①．The first thing that we should do is to work out a plan .②．I t almost seemed as if the good man were trying to teach us all that he knew at this lesson .③．Later my father and Mr. Crosset talked for about half an four of things and persons that they remembered in school.④．This is the very dictionary that I want to find .（2）．只用which is 情况有两种情况：一是非限制性定语从句，关联词要用which；二是做介词宾语时只能用which。
请看下列两组例句：I said nothing , which made him more angry .I have the book about which you are talking .三、在定语从句的非限制性定语中，which 和as 是容易混淆的。
在很多情况下两者兼可互换，但在下列情况中不可互换：1、通常As 可以放在整句的句首，而which，只能在逗号之后，as 本身含有“正如”，as 在定语从句中既可是主语也可做宾语As appear from her paper ,she has read widely in Romantic literature.She is remarkable, as I have told you .2、which 在做非限制性定语从句关联词时可以无明确先行词，指前句整个的意思，如：She has married again, which surprises us .四、在定语从句中，许多人往往分不清all that 和what, what 实际上只引导名词性从句，它相当于all that两个字，例如：All that I know is that he has made up his mind to heave the country for a new place.= what I know is that ……定语从句知识要点：一、限定性定语从句：注：先行词是time, minute, moment, next tim 很少用关系副词when,可用that 但通常省去。
定语从句-高一英语语法专题
高一英语语法专题定语从句一、概念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，一般紧跟在它所修饰的先行词后面。

注：that和which在从句中作宾语时常可省略。
e.g. The number of the people that come to visit the city each year rises one million.e.g. Football is a game which is liked by most boys.2.代表物时多用which，但在带有下列词的句子中用that而不用which：当先行词是anything, everything, nothing , none等不定代词时，或者是every, any, all, some, no, little, few, much等修饰时等，或者是有序数词或形容词最高级修饰时、既有人又有物时、句中前面有which时都只能用that。
3. who和whom引导的从句用来修饰人，who作从句中的主语,whom作宾语e.g. The boys who are playing football are from Class One.e.g. Mr. Ling is just the boy whom I want to see.e.g. The man who/whom you met just now is my friend.4. 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。

四、限定性定语从句和非限定性定语从句的区别1.限定性定语从句：限定性定语从句与主句的关系十分紧密，缺之不可，对先行词起限定、修饰的作用。
如果将其去掉，会影响句子完整性，甚至意义不明。
限定性定语从句的先行词前面不可加其他定语修饰词，并且不用逗号隔开。
2.非限定性定语从句：非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，它与主句之间通常用逗号隔开。
非限定性定语从句前面可以加其他定语修饰词。
非限定性定语从句先行词为专有名词或者具有特指性的名词时，一般不用that。
非限定性定语从句还可以由as引导。
