高考英语语法定语从句
高考英语复习6.定语从句（语法）
高考英语复习6.定语从句（语法）语法讲座：定语从句一、先行词、关系代词和关系副词1．先行词(antecedent)就是被定语从句所修饰的名词。
在英语中，定语从句跟在被修饰词之后，所以被修饰词就是“先行”的词。
2．连接定语从句，要用关系代词(relative pronoun)和关系副词(relative adverb)。
关系代词和关系副词与连接词不完全相同，因为它们除了连接主句和定语从句，还在定语从句中代替一定的成分。
二、关系代词1．who先行词是“人”，在从句中代替主语。
注意：代替从句中的主语，who不能省略。
who的单复数由先行词决定。
但是要注意“one of +先行词”与“the only one of +先行词”的情况。
2．whom先行词是“人”，在从句中代替宾语。
whom在从句中经常可以省略，但如果在介词后面，则不能省。
3．which先行词是“物”，在从句中可以代替主语或宾语。
which代替主语时，不能省略，它的单复数由先行词决定。
which 代替宾语时则经常省略，但如果在介词后面，那么也不能省略。
which的先行词有时还可以是前面的整个句子，这时它总是看成单数，也不能省略。
4．that先行词可以是“人”，也可以是“物”，在从句中可以代替主语或者宾语。
that代替主语时，不能省略，代替宾语时则经常省略。
that不能用在介词之后。
在以下三种情况时，我们一般不用关系代词who, whom, 和which，而只用that：1）先行词是不定代词如anything, something, all等词，或由all, every, little, any, much, the very 等词所修饰；2）先行词前有最高级形容词或序数词所修饰；3）先行词是由and连接的两个词，分别指“人”和“物”。
5．whose先行词可以是“人”，也可以是“物”，在从句中代替定语。
whose不能省略。
如果先行词是“物”，我们也可以用sth. of which代替whose。

2023届高考英语定语从句(通用3篇)
2023届高考英语定语从句（通用3篇）2023届高考英语定语从句篇1语法复习四：定语从句（一）定语从句一般由关系代词和关系副词引导1、关系代词：who, whom, whose, which, that, as2、关系副词：when, where, why关系代词和关系副词必需位于从句之首，主句先行词之后，起着连接先行词和从句的作用，同时在从句中又充当句子成分。
e.g. she is the girl who sings best of all.（关系代词who在从句中作主语）the comrade with whom i came knows french.（whom在从句中作介词with的宾语）3、关系代词和关系副词的用法：1）当先行词为人时用who 作主语，whom 作宾语；2）当先行词为物或整个句子时用which ，可作主语或宾语；3）先行词为人、物时用that ，可作主语或宾语；4）whose用作定语，可指人或物；5）关系副词when（指时间，在定语从句中作时间状语，where（指地点，在定语从句中作地点状语），why（指缘由，在定语从句中作缘由状语）。
（二）限制性定语从句与非限制性定语从句1、限制性定语从句：从句与主句关系亲密，去掉从句，主句意义不完整，甚至不合规律。
e.g. i was the only person in our office who was invited.（去掉定语从句，意思就不完整）2、非限制性定语从句：从句对先行词关系不亲密，去掉定从句，意思仍旧完整。
形式上用逗号隔开，不能that用引导。

1）用that而不用 which的状况：①先行词为不定代词all, anything, nothing, …；②先行词有最高级修饰，有序数词修饰；③先行词有only, very, any等词修饰；④先行词既有人又有物时。
高考英语语法定语从句讲解与练习附答案
定语从句与高考定语从句是高考的热点，主要考查关系代词和关系副词的正确运用，特别是它们在非限制性定语从句中的运用。
主要考点有：1.关系代词who, which, that, whom, as, whose的基本用法。
2.关系副词when, where, why的基本用法。
3.定语从句中关系词的特殊用法。
4.定语从句中“介词＋关系代词”介词的确定。
5. which/ as引导的非限制性定语从句的区别。
一、定语从句的分类限制性定语从句定语从句非限制性定语从句二、限制性定语从句和非限制性定语从句的区别区别一：形式不同限定性定语从句主句和从句之间不用逗号隔开；而非限定性定语从句与主句之间通常____用___逗号隔开。
区别二：功能不同限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意____不明确___；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意不影响。
如：People who take physical exercise live longer. 进行体育锻炼的人活得长些。
(若把从句去掉句子就失去意义)His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。
(若把从句去句子意义仍然完整)比较下面的两个句子：I have a sister who is a doctor. 我有一个当医生的姐姐。
(姐姐不止一个)I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。
(只有一个姐姐)区别三：翻译不同在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。
如：He is the man whose car was stolen. 他就是汽车被窃的那个人。
I’ve invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。

高考高中英语核心语法详解 定语从句
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。
高考英语语法之从句讲义：定语从句精讲
高考英语语法之从句讲义：定语从句精讲充当定语的句子叫定语从句。
定语从句修饰的名词叫先行词(the antecedent).定语从句由关系代词: who, whom, which, 关系形容词whose 和关系副词when, where, why引导，关系词除了起连接从句和名词的作用外，还作从句的句子成分。
1.限制性定语从句Who的先行词是人，作定语从句的主语：This is the man who will give us a talk tomorrow.Whom的先行词是人，作定语从句的宾语：This is the man whom I talked about the other day.Which 的先行词是物，作从句的主语和宾语Here is a book which may be helpful in you English study.This is the book which I like best.上述例句都可改用that.Whose是个关系形容词，在从句中作定语。
A teacher is a person whose duty is to teach.When, where, why 分别作从句的时间状语、地点状语和原因状语。
He will never forget the day when the accident took place.This was the room where we studied.Do you know the reason why he was late?2.非限定性定语从句：非限定性定语从句所修饰的先行词可以是名词（许多是专有名词），也可以是整个主句，它对先行词不加限定，只起附加说明作用，如果没有，也不影响句意和语法结构。
非限定性定语从句和先行词书写时有逗号断开。
Yesterday I happened to see John, who was eager to have a talk with you.She was late again, which was annoying.区分限定性定语从句和非限定性定语从句很重要。
高考英语语法定语从句考点突破
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。

定语从句详解⾸先，（任何）从句结构：“关联词+从句主语+从句谓语”位置：从句之⾸，主句先⾏词之后。
成分：关系代词和关系副词均在定语从句中充当句⼦成分。
⾮限制性定语从句：（1）反作补充说明，与主语关系不甚密切，朗读时先⾏词⽤降调并稍做停顿，多半逗号与主句隔开。
（2）能修饰整个句⼦，限制性定语从句则不能。
与限制性定语从句含义不同，限制-是确指，⾮限制性定语从句是泛指。
（3）先⾏词为{专有名词，具有特指对象的名词}⼀般要⽤到⾮限制性定语从句。
（4）关系代词不能⽤that ，先⾏词指{⼈：⽤who、whom；物：which }关系代词与介词“介词+关系代词”既能引导⾮限制性定语从句，⼜能引导⾮限制性定语从句。
介词要根据先⾏词、从句的谓语动词、从句中的形容词来选择，也可根据句意选择。
I．介词放在关系代词的前⾯时，介词短语只能⽤which代物；和⽤whom代⼈；whose还可在从句中与它所修饰的词⼀起作介词宾语。
This is the hero of whom we are proud.I want to find the very pen with which I wrote that letter.The boss in whose company my father worked is a very kind person.II．当介词放在句⼦的末尾时，可⽤that/which代物，that/whom/who来作为介词的宾语，且这个做介词宾语的关系代词往往忽略This is the hero that (who/whom/忽略) we are proud of.特:(1)from where为”介词+关系副词”结构,where作from的宾语,但也可引导定语从句。
例如:We stood at the top of the hill,from where we can see the town.(2) 有些动词+介词所组成的短语动词，关系⾮常紧密，介词不能前置。

高考英语定语从句
高考英语定语从句
高考英语定语从句是高考考试中重要的语法知识点之一。
定语从句用来修饰名词或代词，限定或说明其特定的属性、特征或身份。
在考试中，经常会出现关于定语从句的题目，需要考生掌握该知识点并正确运用。
定语从句通常由关系代词或关系副词引导，常见的关系代词有：that, which, who, whom, whose；关系副词有：where, when, why。

宾语或介词宾语时，不可省略。
定语从句的结构分为限制性定语从句和非限制性定语从句。
限制性定语从句是对前面的名词进行限定，如果去掉该定语从句，整个句子的意思会发生改变或不完整；非限制性定语从句是对前面的名词进行补充说明，如果去掉该定语从句，整个句子的意思仍然完整。
在使用定语从句时，需要注意一些常见的错误。

要掌握定语从句的正确使用，需要多进行相关的练习和例句的分析。
培养整体理解句子的能力，了解句子之间的逻辑关系，以便正确判断定语从句的引导词和相应位置。

高考英语语法填空之定语从句
高考英语语法填空之定语从句一：知识储备1．确定是定语从句设空处无提示词，而设空前的主句完整；设空后的句子不完整，且对设空前的某一名词或代词起限定作用，考虑填定语从句关系词。
2．掌握3步法解题技巧第1步：分清限制与非限制在先行词的后面出现逗号的，是非限制性定语从句。
①that不能引导非限制性定语从句。
②which引导非限制性定语从句可代表主句的全部或部分内容，which意为“这一点”。
③as引导非限制性定语从句，可放句中或句首，意为“正如”。
其后的谓语动词多是be seen，be known，be reported，be mentioned，be said，is often the case等。
第2步：寻找先行词，辨别人与物①先行词指人：用that/who/whom/whose；②先行词指物：用that/which/whose等。
第3步：判断所缺成分，确定关系词①缺少主语：that/which/who；②缺少动词的宾语：that/which/who/whom；③缺少介词的宾语：whom/which；④缺少定语：whose；⑤缺少时间、地点或原因状语时：分别用when，where，why。
3．必记定语从句中的2个高频考点①当先行词为表示抽象地点的名词，如point，situation，case，stage等，若在从句中作状语，用关系副词where引导定语从句；若作主语或宾语，则用关系代词that/which。
②先行词为表示时间、地点或原因的名词，在从句中作状语时，用when/where/why引导从句；在从句中作主语或宾语时，用that或which引导从句。

高考英语 语法专项 语从句
落堕市安心阳光实验学校高级中学高考英语语法专项定语从句一、知识点拨：定语从句，也称之为形容词性从句，在复合句中修饰、限定某一名词、代词或相当于名词的词组或句子。
被定语从句所修饰的名词或代词叫先行词；引导定语从句的词叫关系词。
关系词可分为关系代词：that , which , who , whom, whose, as 在从句中作主语，宾语，表语，定语；关系副词：when, where, why在从句中作状语。
例如：1. The man who lives next to us sells vegetables.2. You must do everything that I do.3. Do you remember the afternoon when we first met three years ago?上面两句中的man和everything,afternoon是被定语从句修饰的词，叫先行词，其后的黑体部分为定语从句，其中who和that,when叫关系词，分别在从句中作主语，宾语和状语。
二、认识定语从句：划出下列复合句中的定语从句部分，找出各个句子中的先行词，关系词。
