高考英语定语从句详细解析
高考英语定语从句详细解析在句中修饰名词或代词的从句，因其修饰作用相当于形容词，故称形容词性从句，即通常所说的定语从句。
被定语从句修饰的词叫先行词，区别定语从句和名词性从句的最简易的办法就是看从句前有无被修饰的先行词。
引导定语从句的关系词既起着联系作用，同时又作定语从句的一个成分。
这些关系词包括：1）关系代词：先行词为人：________、_________ 、_______、________。
先行词为物：________、________、________、________ 。
2）关系副词：_________ 、_______、________。
注意：引导定语从句的关系词和引导名词性从句的连接词有许多是共用的，但它们在从句中的作用有所不同，注意区别。
尤其要注意的是what只能引导名词性从句，不能引导定语从句。
定语从句一般紧跟在先行词后，但有时也被一个短语隔开。
例如：I was the only person in my office who was invited.1．关系代词的用法：关系代词在从句中充当主语、宾语、定语或表语等成分。
The comrade ______ visited our class yesterday is our new headmaster.（作主语）He is no longer the man ______ he used to be. （作表语）This is the book ______ I referred to in my talk. (作宾语)Wei Fang is the student ______ home caught fire last week. (作定语)使用关系代词值得注意以下几点：①that, which在从句中作主语时，不能省略；作宾语时，在口语和非正式语中经常省略。
whom 也常可省略。
例如：He is the man (whom) you have been looking for. （作宾语）②that, which在从句中作主语时，如果先行词前面有序数词、最高级以及有the only，the very等修饰时，只能用that, 不能用which。
(word完整版)英语定语从句用法详解
英语定语从句用法详解在复合句中，修饰名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词，引导定语从句的有关系代词 who, whom, whose， which, that等和关系副词where， when, why等，关系代词和关系副词在定语从句中担任句子成份.1.由who引导的定语从句中， who用作主语，如： This is the boy who often helps me.2。
由whom引导的定语从句中，whom用作宾语，如：The man whom you are waiting for has gone home.3.由whose引导的定语从句中， whose用作定语，如： Do you know the girl whose skirt is white? 4。
由which引导的定语从句中，which用作主语或谓语动词的宾语或介词的宾语，如：The room in which there is a machine is a work shop。
The river which is in front of my house is very clean.This is the pen which you want。
注意：(1）whom, which用作介词宾语时，介词可放在 whom、which之前 , 也可放在从句原来的位置上;但在含有介词的动词固定词组中，介词只能放在原来的位置上。
如： He is the very person whom we must take good care of.(2）引导非限制性定语从句时，必须用关系代词which，不用that，如：I have lostmy bag， which I like very much.（3）关系代词在句中作主语时，从句的谓语动词的人称和数必须和先行词保持一致.5.由that引导的定语从句中，that可以指人或物,在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语,如：The book that I bought yesterday was written by Lu Xun.注意在下面几种情况下必须用 that引导定语从句。

初中英语定语从句(全,含练习及答案解析)
（一）定语从句的概念定语从句：一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。
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。
因此，Handsome boy = the boy who is handsomeBeautiful flower = the flower which is beautiful被定语从句修饰的词叫先行词，引导定语从句的词叫关系词。
关系词可分为关系代词（who, whom, whose, which, that)和关系副词(when, where, why)关系词都充当从句的某个成分，它所替代的相应成分应省去。
在定语从句中，当who, which, that作主语时，谓语的单复数应与先行词保持一致。
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。
定语从句分为限制性定语从句和非限制性定语从句。
非限制性定语从句与先行词的关系不如限制性定语从句与先行词的关系紧密，没有它，主句的意思也清楚，因此用逗号隔开。
关系词在非限制性定语从句中的用法与在限制性定语从句中的用法基本一样。
（二）关系代词用法作用例句关系代词指示对象That人/物主（宾）The student that answered the question was John.回答问题的学生是约翰。
The book （that）you lent me was interesting.你借给我的那本书很有趣。
Which物主（宾）Football is a game which is liked by most boys. 足球是大多数男孩都喜欢的游戏.This is the pen (which) he bought yesterday. 这是他昨天刚买的钢笔.Who人主（宾） A doctor is a person who looks after people's health.The man（who）you met just now is my friend. Whom人（宾）The man（whom）you met just now is my friend. 你刚刚见到的那个人就是我的朋友.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.Whose人.物定He has a friend whose father is a doctor.Please pass me the book whose (of which) cover is green.注意一：1）介词后面的关系词不能省略。

定语从句讲解
定语从句一、关于定语从句的简单的概念1．先行词：被定语从句所修饰的词。
2．关系词：是指连接先行词和定语从句并且在定语从句中做一定成分的词，既包括关系代词，又包括关系副词。
3．定语从句一般放在被修饰的名词后面。
例如：I don’t like the doctor who asks too many questions.先行词关系词（整个斜体部分为定语从句）上句是由这样的两句变化出来的。
1：I don’t like the doctor.2：The doctor asks too many questions.主语第二句变为第一句的定语从句时将the doctor 用关系代词“who”取代，放在第一句所修饰的名词（the doctor）后面，”who”在定语从句中所做成分是主语。
二、找正确的关系词的方法：瞻前顾后瞻前：先看先行词是人还是物，还是表时间地点的名词。
顾后：看关系词在后面的定语从句中所做的成分。
三、非限定性定语从句非限定性定语从句是对主句先行词的补充说明，没有从句并不影响主句意思的明确或完整。
这种从句一般用逗号与主句分开。
在非限定性定语从句中，一般通常不用关系代词that。
有时，主从复合句中的定语从句是限定性的还是非限定性的取决于全句意思或上下文。
限定性定语从句是句子中不可缺少的组成成分。
如没有限定性定语从句，先行词的意思就不明确，主句也不完整，从句和主句之间不用逗号分开。
四、在定语从句中只能用that的情况1．在先行词为all, everything, nothing, something, anything, little, much等不定代词。
2．先行词被all, every, no, some, any, little, much等词修饰。
3．先行词被the only, the very, the same, the last 等词修饰。
4．先行词被序数词或形容词的最高级修饰时。
5．当先行词既包含人有包含物时。

定语从句解析
定语从句在句中起定语作用，修饰某一名词或代词，或修饰整个主句的从句，叫作定语从句。
被定语从句修饰的词叫做“先行词”，定语从句通常跟在先行词之后，主要由关系代词who, whom, whose, which, that和关系副词when, where, why引出，它们在意义上代表先行词，同时在定语从句中担任某种句子成分。

1)先行词指物时，用关系代词that/ which在从句中作主语或宾语。
如：He bought a coat that/which cost little．他买了一件花钱很少的大衣。
（作主语）The car which/ that he bought yesterday is a secondhand one.他昨天买的车是二手车。
（作宾语）2)先行词指人时，用关系代词that/ who在从句中作主语或宾语（在口语中who代替whom）。
如：The man who/that gave a speech on TV is the president.发表电视讲话的人是总统。
（作主语）This is the strange man that/ who/whom I met yesterday.这就是我昨天遇到的陌生人。
（作宾语）3)whose在从句中作定语，既可指人，作“某（些）人的”解，也可指“物”，作“某（些）物的”解。
如：This is the little girl whose parents weer killed in the great earthquake.这就是父母在大地震中死亡的那个小女孩。
4)We live in a house whose windows open to the south.我们住在窗户朝南的房子里。

定语从句语法讲解
定语从句语法解析
哎呀，说起这个定语从句，咱们得细细道来，免得整得一头雾水。
你想啊，它就像是个“贴身保镖”，专门给名词或者代词整点“背景资料”，让它们看起来更“有料”。
首先，咱们得明白这定语从句的“三件套”：先行词、关系词、从句部分。
先行词嘛，就是你要“保卫”的那个名词或代词；关系词呢，就像个“桥梁”，把先行词和从句连起来，常用的有“那个”、“啥子”之类的；从句部分，就是具体说明先行词的那些话了。
再来说说分类，它分两类：限制性和非限制性。
限制性定语从句没得它，句子就不完整，就像少了盐的川菜，没味儿；非限制性呢，就像是菜里的葱花，有它更好，没它也成。
关系词里头，who、whom、whose、that、which这些个，各有各的用处。
比如，说人的时候，who和whom就派上用场了；说物呢，which和that就得出来“耍”了。
注意哈，有些时候只能用that，不能用which，比如先行词是“啥子都”、“全部”这些个词的时候。
还有啊，这定语从句里头还有省略的小技巧。
要是关系词在从句里头作宾语，那就可以直接省略了，整得句子更简洁。
最后，咱们得记住，这定语从句是个好东西，用好了能让你的句子更生动、更有层次感。
就像咱们四川话一样，虽然直白，但里头也是讲究得很，多听多说，自然就通了。

定语从句1.定语从句——修饰名词或代词的从句。
换句话说，名词、代词后的从句叫定语从句。
2.先行词——被定语从句修饰的名词、代词、甚至词组或句子叫先行词。
3.关系词——引导定语从句的词叫关系词。
4.关系词分两种：一是关系代词(在定语从句中担任主、宾、表、定语成分)二是关系副词(在定语从句中担任状语成分)关系词的三个功能：1. 连接功能（连接先行词与定语从句）；2. 担任功能（在定语从句中担任主、宾、表、定、状语）；3. 替代功能（在定语从句中代替先行词）。
A plane is a machine. The machine can fly.A plane is a machine, and the machine can fly.A plane is a machine that can fly.5.关系代词有：who, whom, whose, that, which, as在定语从句中可担任主语的是：who, that, which, as在定语从句中可担任宾语的是：who, whom, that, which, as在定语从句中可担任定语的是：whose, which当先行词是人时，可用的关系词是：who, whom, that, as当先行词是物时，可用的关系词是：which, that, whose, as6.关系副词有：when (先行词为时间),where (先行词为地点),why (先行词为原因)关系副词 = 介词 + which / whom7.定语从句分为两种：限制性与非限制性。
先行词与关系词之间无逗号隔开为限制性；有逗号隔开则为非限制性。
非限制性定语从句一般不可用关系代词that 引导。
唯一可以置于先行词之前的定语从句由关系代词as 引导二.关系代词引导的定语从句1.who指人，在从句中做主语或宾语(1) The boys who are playing football are from Class One.(2) Yesterday I helped an old man who lost his way.2. whom指人，在定语从句中充当宾语，常可省略。
(1) Mr. Liu is the person (whom) you talked ab out on the bus.(2) Mr. Ling is just the boy whom I want to see .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。
(3) The man who/whom you met just now is my friend.3. 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.(2) This is the pen (which) he bought yesterday .4. that指人时，相当于who 或者whom；指物时，相当于which。
在宾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 m orning?5. 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 broken.whose指物时，常用以下结构来代替(3) The classroom whose door is broken will s oon be repaired.(4) The classroom the door of which is broken will soon be repaired.(5) Do you like the book whose cover is yellow ?(6) Do you like the book the color of which is y ellow?三.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.(2) The school in which he once studied is very famous.(3) Tomorrow I will bring here a magazine (tha t/which) you asked for.(4) Tomorrow I will bring here a magazine for which you asked.(5) We'll go to hear the famous singer (whom/ that/who) we have often talked about. (6) We'll go to hear the famous singer about w hom 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(1) This is the watch which/that I am looking f or. (T)(2) This is the watch for which I am looking. (F) 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)(2) The man who/that you talked with is my fri end. (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 who are from big cities.四．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 wantedwhen he grew up.(3) Great changes have taken place in the city in which/where I was born.五．限制性定语从句和非限制性定语从句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：（关系词不可省略）(1) His mother, who loves him very much,is strict with him.(2) China, which was founded in 1949, is beco ming more and more powerful.限制性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体，更明确。
限制性定语从句不能被省略，否则句意就不完整。
非限制性定语从句与先行词关系不十分密切，只是对其作一些附加说明，不起限定制约作用。
如果将非限制性定语从句省去，主句的意义仍然完整。
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every, any, all, some, no, little, few, much 等修时(1) Have you taken down everything that Mr. Li has said?(2) There seems to be nothing that seems imp ossible 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 wo n'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. 当先行词被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 histheory 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。
