高考英语从句综合知识点高考英语从句是考试中的重要部分，对于学生来说也是一个相对难以掌握的知识点。
在复习过程中，学生需要综合掌握从句的各种类型及正确的用法。
在这篇文章中，我将为大家总结一些高考英语从句的综合知识点。
一、名词性从句名词性从句主要有三种形式：主语从句、宾语从句和表语从句。
在考试中，我们需要根据不同的语境来正确地使用它们。
1. 主语从句：主语从句在句子中充当主语成分，常用连词有that和whether/if。
例如：Whether we will win the match is still uncertain.（我们是否能赢得比赛还不确定。
）2. 宾语从句：宾语从句在句子中充当宾语成分，常用连词有that, whether/if, 还有一些特殊的动词后接宾语从句，如hope, suggest, advise 等。
例如：They suggested that we should go hiking this weekend.（他们建议我们这个周末去远足。
）3. 表语从句：表语从句在句子中充当表语成分，常用连词有that和whether/if。
例如：The question is whether he will come to the party or not.（问题是他是否会来参加派对。
）二、定语从句定语从句用来修饰名词或代词，在句中充当定语成分。
在日常口语和写作中，定语从句的使用频率相对较高，因此熟练掌握其用法对于高考很有必要。
定语从句的关系词有：that, which, who, whom, whose等。
我们需要根据先行词在定语从句中的作用来选择合适的关系词。
1. 关系代词that和which的区别：that用于限定性定语从句中，不可以省略。
而which则用于非限定性定语从句中，用于修饰整句的内容，可以省略。
例如：The book that I borrowed from the library is very interesting.（我从图书馆借来的那本书非常有趣。
定语从句总结一：定语后置的总结〔1〕介词短语作定语：the landlady in the bad situation/ the way in error/ thethiefwith a gun / the communication in English /The student in sorrow didn’t pass the English exam.〔2〕表语形容词作定语：the presidents alive in the U.S.A are all male.〔3〕不定合成代词被修饰：Although I had dinner tonight, I still need something delicious tohave.〔4〕副词作定语：the students here are all come from Shenyang.〔5〕不定式作后置定语：the destination to go / the cookbook to use / the movie to cast/ the match to fire / the classical music to listen / the hammerto use / the task to finish〔6〕现在分词作定语：the man pronouncing the wrong pronunciation is a principal. 〔7〕过去分词作后置定语：the service given in the hotel is 5-star. / the signal signed bythe students are for cheating in the final exam.(P10-1) English is a language spoken all around the world.(P10) In only fifty years, English has developed into thelanguage most widely spoken and used in the world.〔8〕定语从句：〔P4〕The lesson (that) we can learn from Chuck and all others who haveunusual friends is that friends are teachers.二：定语从句的概念和公式特点(P3-1):关系代词在从句中作主语Chuck is a businessmanwho is always so busy that he has little time for his friends.先行词〔被修饰的名词或代词〕+ 关系词〔起连接作用的代词和副词〕+〔,〕定语从句〔在句中作成分〕三：定语从句的分类When I took the money from her grandfather, I looked back at the girl, who was giving me the prettiest, largest smile (that)I have ever seen.限定性定语从句和非限定性定语从句的区别1：限定性没有逗号，非有逗号。
高考英语要考的定语从句考点统计汇总定语从句作为英语语法，在学习过程中属于中较难理解与掌握的部分，也正是由于其复杂程度较高、逻辑性较强、理解难度很大。
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who Who 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。
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。
高考高中英语核心语法详解定语从句关系从句//定语从句一、基础知识1. 由来：两个句子之间要有一个重复元素产生关联。
重复点上改写为关系词，由此产生关系从句。
这个重复点在主要从句中称为先行词（antecedent）。
在关系从句中称为关系词，分为关系代词和关系副词。
结构一般比较固定：先行词+关系词+从句例：The boss lives opposite my house. 那位老板住在我家对面。
He is very rich. 他很富有。
说明：the boss 和he 为重复点；下面保留boss，把he改写为who，组成一句话：The boss who lives opposite my house is very rich. 住在我家对面的那位老板很富有。
boss称为为先行词；who为关系引导词；who引导的句子称为关系从句或定语从句。
2.内涵:忌重复原则决定，目的让句子更紧凑；尾重原则，决定重点信息后置。
3.先行词：被关系从句所修饰的词The tall man who is standing over there is my uncle. 正站在那儿的高个子男士是我叔叔。
man为先行词。
4. 关系词：让两个句子产生关联；具有双重角色；（1）角色一：代替前面的先行词；（2）角色二：起到连接作用，并在其引导的句子中承担相应语法成分；例：This is the book that I bought yesterday. 这是我昨天买的那本书。
that代替前面的先行词book; that同时是其引导句子中bought的宾语。
5. 限制性定语从句与非限制性定语从句区分口诀: 有无逗号；限定不限定；展开不展开；a. 限制性: 从句紧跟先行词，两者之间无逗号，并且句意特别指定先行词，并不展开。
b.非限制性：先行词与从句中间用逗号隔开;句意非特指不限定，从句继续展开。
例：限制性There is a tribe of busy little people who live in the Frozen Zone.一个忙碌的小人部落住在冰冻区。
高中英语语法总结大全之定语从句定语从句定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，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等。
关系副词有：when, where, why等。
关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
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?他就是你想见的人吗？（who/that在从句中作主语）He is the man whom/ that I saw yesterday.他就是我昨天见的那个人。
（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.那人车坏了，大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green.请递给我那本绿皮的书。
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. 农村出现了前所未有的繁荣。
（which / that在句中作宾语）The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。
高中语法专项定语从句专题思维导图：1. 定义：在复合句中充当定语的从句，即一个句子作定语（=形容词）。
2. 关系代词在定语从句中充当主语、宾语、表语、定语3. 关系副词在定语从句中作时间、地点、原因状语1. 关系代词who, whom, which, that, whose, as4. 限制性定语从句 2. 关系副词when, where, why定语从句 3. 从句对先行词起修饰限定作用，二者关系密切1. 关系代词who, whom, which, whose, as5. 非限制性定语从句 2. 关系副词when, where, why3. 从句只对先行词起补充说明作用，主从句常用逗号隔开定语从句一定没有what和how，非限制性定语从句一定没有that。
1.关系代词的基本用法2.关系代词that和which的用法区别3.关系代词as和which的用法区别4.关系副词的基本用法5.定语从句的其他用法要点一. 关系代词的基本用法导入：1.He has two sons and both of them are teachers.2.He has two sons, both of whom are teachers.基本用法：注意：（1）关系代词在定语从句中作主语时，不可省略。
在定语从句中作宾语时whom/who/which/that可以省略，as一般不省略。
（2）whose可与of which转换。
Whose = the + 名词+ of whichWhose = of which + the + 名词This is the house whose window broke last night.= This is the house, the window of which broke last night.= This is the house, of which the window broke last night.（3）such....as....结构（as引导定语从句）与such....that...结构（that引导状语从句）的区别例句：1.It is such a big stone as no man can lift.2.It is such a big stone that no one can lift it.二. 关系代词that和which的用法区别1.限制性定语从句中，必须用关系代词that的情况。
高考英语语法定语从句考点突破一、基本概念1．定语从句：在一个主从复合句中修饰某一个名词、代词或修饰整个主句的从句叫定语从句。
换句话说，定语从句就是用来作定语的句子。
2．先行词：被定语从句修饰的名词或代词叫先行词。
先行词前一般用the ，但在指“一个”概念时可用 a , an 。
3．关系代词/ 关系副词：连接先行词和定语从句的词叫关系词，根据其在从句中作用分为关系代词或关系副词。
若先行词在从句中作主语、宾语和定语等，应用关系代词引导定语从句；若先行词在从句中作时间状语、地点状语和原因状语等，应用关系副词引导定语从句。
4．定语从句的位置：一般紧跟在先行词后面。
但有时因句子结构的需要，定语从句和先行词被某些成分隔开。
5．引导定语从句的关系词分为二类：关系代词：that, which ,who, whom ,whose , as关系副词：when, where, why二、基本用法1．关系代词的基本用法（见下表）：2．使用关系代词时应注意的几个问题：a. 在以下几种情况下只使用that不用which。
1.先行词是不定代词时，如: all, anything, everything, nothing, something, little, few, much。
1.I told him all (that) I know.2.He gave her everything (that) he had.2.先行词被all, every, any, the very, the only, the just等修饰时。
1.I have read all the books (that) you gave me.2.You can take any book (that) you like.3.先行词被序数词和形容词的最高级修饰时。
1. This is the best book (that) I have ever read.2. The second place (that) I want to visit is Shanghai.4.先行词既有人又有物时。
干货高中英语语法归纳总结大全，高考必备1.定语从句引导定语从句的关系代词有that,which,who（宾格whom），所有格whose）和关系副词where when why 等，关系代词或关系副词在定语从句中充当一个成分，关系代词that，which,who,whom等在从句中分别作主语或宾语，whose 在从句中作定语，而关系副词when,where,why等在从句中作状语。
如：①I will never forget the days when/in which we worked together.②I will never forget the days which/that we spent together.解析：在句①中，表示时间的名词the days在从句中充当的是状语，所以用关系副词when来代指，引导定语从句修饰先行词the days；而在句②中，表示时间的名词the days在从句中充当的是动词spent的宾语，所以用关系代词that或which来代指。
同样，表示地点或原因的名词如果在从句中作状语，则用关系副词where 或why 来代指；如果在从句中作动词的宾语，则用which或that来代替。
如：①This is the factory where/in which I worked.（作状语）②This is the factory that/which I visited years ago.（作宾语）注：当先行词为time,reason, place时，引导词可以省略。
①This was the first (when/what) I had serious trouble with my boss.②That is the reason (why) I did it.③This is the place (where) we met yesterday.另外，定语从句中谓语动词的数应与先行词的数相一致。
