高考英语定语从句考点整理概念定语可以由形容词、名词、代词、分词、不定式以及介词短语等来担任，也可以由一个句子来充当，充当定语功能的句子称为定语从句。
定语从句“三要素”1.先行词：被定语从句所修饰的名词或代词①指人的先行词②指物的先行词★先行词还可以是前面整个句子所叙述的事情。
He has passed the driving test, which surprises all of us. (which替代前面所叙述的事情) 先行词2.关系词：引导定语的词(1)关系词的作用①替代前面的先行词（替代作用）②连接主句和定语从句（连接作用）③在定语从句中作句子成分（成分作用）(2)关系词的分类①标准：根据关系词在从句中做的句子成分种类②关系代词：在从句中做主，宾，表，定（that/which/who/whom/whose/as）③关系副词：在从句中作状语(When/where/why)3.定语从句：用来做定语，修饰限定先行词的句子定语从句的分类1.限制性定语从句：对先行词起限定修饰作用。
He is a teacher who works at our school.2.非限制性定语从句：对先行词起补充说明作用(先行词与定语从句之间有逗号隔开)Beijing, which is the capital of China, is a beautiful city with a long history.比较：He has two sons, who work in the same company.(He has only two sons.)He has two sons who work in the same company.(Perhaps he has two more sons)定语从句的10个难点1.关系代词的省略(限定性定语从句)(1)关系代词在定语从句中作宾语She is the girl (whom / that) I loved before. (可以省略whom/that)(2)关系代词在定语从句中作表语He is no longer the boy (that) he used to be. (可以省略that)(3)关系代词作介词宾语，介词在从句句尾时可以省略Housing price is a problem (that/which) people are interested in.比较：Housing price is a problem in which people are interested.（此时只能用which且不能省略）2.先行词是人(that/who的区别)(1)用that的情况①以疑问词who开头的句子中Who is the man that is shouting there?②关系代词在从句中作表语时She is not the girl that she used to be.③先行词被the very, the right, the only修饰This is the very person that we are looking for.(2)用who的情况①先行词是one, ones, anybody, all, none, those 等Those who want to go to the cinema will have to wait at the gate of the school.②句子中有两个定语从句,一个用了that,另外一个用whoWho is the boy that won the gold medal?③在there be 结构中There are many young men who are against him.④在非限定性定语从句当中Tom, who is my best friend, has gone abroad to study.3.先行词是物(that / which的区别)(1)用which的情况①在非限定性定语从句中She lost the game, which depressed her greatly.②关系词置于介词之后，作宾语The pen with which you write is Jack’s.③先行词是that或定语从句中套定语从句,一个关系词用that,另一个用which.Let me show you the novel that I borrowed from the library which is newly open to us.(2)用that的情况①先行词是不定代词如all, little, few, much,anything, everything, nothing, none, no one等She did all that she could to help us.②先行词被all, every, no, some, little, much, the only, he very, the right，the last等所修饰时This is the very book that I want.③先行词中既有人又有物时She described in her compositions the people and he places that impressed her most.④先行词前有序数词或形容词最高级修饰时This is the best book that I have ever read.This is the first film that I’ve seen since I came here.⑤定语从句中套定语从句，其中一个关系词以用which, 另外一个用thatHe built a factory which produced things that had never been seen before.⑥当主句的主语是疑问词which,另一个用thatWho is the person that is standing at the gate?4.As引导定语从句用法(1)As 既可以引导限制性定语从句也可以用于非限定性定句中充当主语，宾语，表语等。
语法复习：定语从句考点易错点归纳考点一：关系代词的用法1.限制性定语从句和非限制性定语从句的区别：1)The girl who/that is holding a pink umbrella is Jim’s sister.2)I like the novel Gone with the Wind very much, which is popular with readers all over the world.①形式上：非限制性定语从句和主句之间用逗号隔开，不能用that引导。
②作用上：限制性定语从句与主句关系密切，对先行词起修饰限制作用，如果去掉从句，主句意义不完整，甚至不合逻辑。
非限制性定语从句与主句关系不密切，对主句起补充说明作用，去掉从句，意思仍然完整。
2.先行词+who/whom引导的定语从句：1)Most students like the teachers _________ can understand them.2)The professor ____________________they want to visit is president of the university.3)Anyone __________laughs last laughs best.4)Do you know the woman with ____________ my manager talked just now?①who在定语从句中作什么成分？②whom在定语从句中作什么成分？③who/whom什么时候可以省略？④什么时候只能用whom⑤先行词为指人的one, ones, anyone, those 时，关系代词常用who。
3.先行词+whose引导的定语从句：1)The prize will go to the writer whose story shows the most imagination.2)The school shop, whose customers are mainly students , is closed for the holiday.①whose :“…的”，其后紧跟______词，在定语从句中作________。

英语语法高中定语从句知识点归纳总结定语从句是英语语法中的一个重要概念，它在句子中起到修饰名词或代词的作用。
在高中英语学习中，掌握定语从句的使用方法和规则对于提高语言表达能力和理解能力非常关键。
本文将对高中英语定语从句的知识点进行归纳总结。
一、定语从句的定义和作用定语从句是一个句子，它修饰一个名词或代词，用来给出更多的信息，进一步描述或限定该名词或代词的特定内容。
定语从句可以用来修饰人、事、物、地点等。
它在句子中的作用是为主句提供更多的信息，使句子更具体、更有表达力。
二、定语从句的引导词1.关系代词：定语从句中常用的关系代词有：- 人：who，whom，whose- 物：which，that，whose- 人或物：as，where，when2.关系副词：定语从句中常用的关系副词有：- 地点：where- 时间：when- 原因：why三、定语从句的基本结构定语从句的基本结构为：关系代词/副词 + 主句。
其中，关系代词或副词在定语从句中担任主语、宾语、表语或定语的作用。
四、定语从句的几个常见类型1.限制性定语从句：限制性定语从句用来对先行词进行进一步的限定，它的信息是先行词不可或缺的一部分。
限制性定语从句与主句之间没有逗号隔开，通常使用关系代词that，也可使用which或who。
例子:The book that you borrowed from me is very interesting.你从我这里借的那本书非常有趣。
2.非限制性定语从句：非限制性定语从句用来对先行词进行附加说明，它的信息只是对先行词的附加补充，可以省略而不影响句子的整体意思。
非限制性定语从句与主句之间用逗号隔开，通常使用关系代词which，也可使用who。
例子:The weather, which was sunny and warm, made our picnic very enjoyable.天气晴朗温暖，使得我们的野餐非常愉快。
高考英语定语从句用法及注意事项一、关系代词引导的定语从句1、that指人或物在从句中作主语，宾语或表语which指物在从句中作主语，宾语或表语（作宾语时可以省略）who指人在从句中作主语，宾语或表语whom指人在从句中作宾语whose指人或物在从句中作定语as指人或物在从句中作主语，宾语或表语but指人或物在从句中作主语，宾语或表语注意：指物时，whose+名词=the+名词+ofwhich或ofwhich+the+名词2、as的用法（1）常用于下列结构：such…as;so…as;thesame…as;as…as注意：thesame…as表示同一类，不同一个thesame…that表示同一个（2）as与which的区别a、位置不同as可放在主句后，主句前或主句中间；which只能放在主句后。
b、as起连接作用，表达说话人的观点、看法，并指出主句内容的根据或出处，意为“正如，正像”。
Which相当于并列句，可以用andthis来代替，意为“这一点，这件事’”。
注意：as常用于下列结构：asweknow/asisknowntoall,asweallcansee,ashasbeensaidbefore/above, asmightbeexcepted,asisoftenthecase,一般不能用which代替as。
c、在从句中作主语时，which既可作系动词be的主语也可作实义动词的主语，而as只可作系动词be的主语。
二、只用that不用which的情况1、先行词为all,much,everything,nothing,something,anything,nothing,none,theo ne等不定代词时。
2、先行词被only,any,few,little,no,all,just,very,right等修饰时。
3、当先行词是最高级或被形容词最高级修饰时。
4、当先行词是序数词或被序数词修饰时。
5、当先行词是数词时。
定语从句相关知识点总结一、定语从句的概念。
1. 在复合句中，修饰某一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，定语从句一般放在先行词的后面。
- 例如：I like the book which/that is very interesting. 其中“book”是先行词，“which/that is very interesting”是定语从句，用来修饰“book”。
二、关系代词的用法。
1. that.- 既可以指人也可以指物，在从句中作主语或宾语。
- 当先行词是all, much, little, something, everything, anything, nothing, none等不定代词时，关系代词用that。
- 例如：All that can be done has been done.（先行词是“All”，关系代词“that”在从句中作主语）- 当先行词被序数词或形容词最高级修饰时，关系代词用that。
- 例如：This is the best film that I have ever seen.（先行词“film”被最高级“the best”修饰，关系代词“that”在从句中作宾语，可省略）- 当先行词被the only, the very, the same等修饰时，关系代词用that。
- 例如：This is the very book that I want.（先行词“book”被“the very”修饰，关系代词“that”在从句中作宾语）2. which.- 指物，在从句中作主语或宾语。
- 例如：The book which/that is on the desk is mine.（“which/that”在从句中作主语）；I like the book which/that you lent me.（“which/that”在从句中作宾语）- 在非限制性定语从句（从句与主句之间用逗号隔开）中，只能用which，不能用that。
高中英语语法知识总结：定语从句下面就是小编给大家带来的高中英语语法知识总结：定语从句，希望能帮助到大家!高中英语语法知识总结：定语从句易错点1 关系代词与关系副词的混用1.定语从句相当于一个形容词，起定词作用，修饰名词或代词2.定语从句的引导词的三种功用:( 1)引导定语从句(2)替代先行词(3)在定语从句中充当一定的成分。
3.解题要领:根据定语从句中所缺成分来确定是用关系代词还是关系副词，决不要因先行词是时间名词就用when，是地点名词就用where。
易错点2 关系代词who、whom、whose的误用对于定语从句关系词的考查，首先要确定从句是什么类型的从句，然后再分析关系词在从句中的成分，最后选择正确的词。
要求考生具有一定的句子分析能力，和理解能力。
如果缺少主宾表，要用that或which，缺少状语用关系副词when，where，why，缺少定语用whose。
易错点3 关系代词that和which的误用只用which，不能用that的情况(1) 在介词提前到关系代词之前形成"介词+关系代词"结构来修饰表事物的先行词时，关系代词必须用which.如：☞The house in which we live is very large. 我们住的房子非常大。
这就是老师正在谈及的那本参考书。
注意：如果介词不放在修饰事物的限定性定语从句的句首，which就可换为that，如：☞This is the question which/that we’ve had so much discussion about. =This is the question about which we’ve had so much discussion. 这就是我们已经多次讨论过的问题。
(2) 先行词为"those+表事物的复数名词"时，关系代词通常只用which而不用that。
如：☞Students should keep in mind those regulations which restrict their behavior.学生应牢记那些规范自己的行为准则。

定语从句1.定语从句基本概念定语从句：在复合句中，修饰名词或代词的从句叫定语从句。
关系词：引导定语从句的词叫关系词。
先行词：被修饰的名词或代词叫先行词。
定语从句一般放在先行词的后面。
2.定语从句的关系词引导定语从句的关系词有关系代词和关系副词。
常见的关系代词包括that，which，who（宾格whom，所有格whose），as 等。
关系副词包括where，when，why等。
关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。
7.注意事项：2. 定语从句中的主谓一致①定语从句中的谓语动词由先行词决定。
例如：I, who am your good friend, will try my best to help you.②当“one of +复数名词”后接定语从句时，从句中的谓语动词和复数名词一致，用复数；而“the only one of +复数名词”后接定语从句时，从句中的谓语动词和the only one一致，用单数。
例如：Susan is one of the students who have won the prize three times.Susan is the only one of the students who has won the prize three times.3. 定语从句中的插入语现象定语从句中的关系词后面有时会加入一些句子作插入语，如I think, I believe, I expect, I guess, I am sure等。
解题时，去掉插入语，会使句子简单化。
例如：Mr Lee made another discovery, which (I think) is very important.4. 通常只用that，不用which, who或whom的情况：①当先行词为all, everything, nothing, anything, little, few, much, none等不定代词时。
