初中英语语法定语从句讲解&练习
初中英语语法——定语从句在复合句中，修饰某一或的从句叫做。
定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后。
如：1) The man who lives next to us is a policeman.2) You must do everything that I do.上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。
引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why关系词常有三个作用：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（二）关系代词引导的定语从句1.who指人，在从句中做主语(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 about.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。
(2) 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. ( which 在句子中做主语)(2) This is the pen (which) he bought yesterday. ( which 在句子中做宾语)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。
(1) The people that/who come to visit the city are all here. (在句子中做主语)(2) Where is the man that/whom I saw this morning? (在句子中做宾语)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 lived in a house whose roof has fallen in.whose指物时，常用以下结构来代替(3)The classroom whose door is broken will soon be repaired.=The classroom the door of which is broken will soon be repaired.(4)Do you like the book whose color is yellow?=Do you like the book the color of which is yellow?注：that 用法(1)不用that的情况(a) 在引导非限定性定语从句时。
(错)The tree, that is four hundred years old, is very famous here.(b) 介词后不能用。
We depend on the land from which we get our food.We depend on the land that/which we get our food from.(2) 只能用that作为定语从句的关系代词的情况(a) 在there be 句型中，只用that，不用which。
(b) 在不定代词，如：anything, nothing, the one, all等作先行词时，只用that，不用which。
(c) 先行词有the only, the very,the same,the last,just修饰时，只用that。
(d) 先行词为序数词、数词、形容词最高级时，只用that,不能用which。
.(e) 先行词既有人，又有物时。
(f) 先行词指物，在主句中作表语时．(g) 为了避免重复．(h)先行词是the way或the reason时，that可作关系副词，也可省略(i) 主句的主语是疑问词who /which时举例：Is this the book that you borrowed in the library?这是你在图书馆借的那本书吗？Who that break the window should be punished．谁打碎了窗户都要受到惩罚．All that is needed is a supply of oil.所需的只是供油问题。
Finally, the thief handed everything that he had stolen to the police.那贼最终把偷的全部东西交给了警察。
（三）关系副词引导定语从句关系副词关系副词：在句中作状语关系副词=介词+关系代词why=for whichwhere=in/ at/ on/ ... which (介词同先行词搭配)when=during/ on/ in/ ... which (介词同先行词搭配)1. where指地点，在定语从句中做地点状语用来表示地点的定语从句。
(1) Shanghai is the city where I was born.(2) The house where I lived ten years ago has been pulled down.2. when引导定语从句表示时间。
在定语从句中做时间状语也可做连接词用(1) I still remember the day when I first came to the school.(2) The time when we got together finally came.[注]表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。
By the time you arrived in London, we had stayed there for two weeks.到你到达伦敦的时候，我们在那里已经待了两个星期。
I still remember the first time I met her. 我仍然记得我第一次见到她。
Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。
每一次他去出差，他带来了生活必需品，如毛巾，肥皂，牙刷等，很多。
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.注：1）介词后面的关系代词不能省略。
2）that前不能有介词。
3）某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when ,where和why 互换。

作用使句子表达更具体、生动，有助于读者或听者更准确地理解所表达的内容。
前置定语通常将定语从句放在被修饰词的前面，如“漂亮的花园”中，“漂亮的”就是前置定语。
将定语从句放在被修饰词的后面，用逗号隔开，如“花园，漂亮的”中，“漂亮的”就是后置定语。
对被修饰词进行必要的限定，使句子意思更明确，如“我喜欢那本红色的书”中，“红色的”就是限定性定语从句。
对被修饰词进行补充说明，去掉后不影响句子意思的完整性，如“我昨天买了本书，它是关于历史的”中，“它是关于历史的”就是非限定性定语从句。
后置定语限定性定语从句非限定性定语从句结构形式与其他从句区别与名词性从句区别名词性从句在句子中充当主语、宾语等成分，而定语从句则充当定语成分，修饰名词或代词。

关于定语从句

语+谓语+其他成分。

初中英语语法——定语从句
定语从句一、考点解读定语从句在初中阶段要求掌握的内容以前不是很多，在以前的教材中，定语从句只是作一些简单的介绍，但现在的新教材中出现的内容较多，而且在中考中的阅读理解、完型填空、汉译英和作文中通常出现含有定语从句的句子，因此我们对于定语从句应该有一个较全面的了解，为在中考中考出高分数打好基础。
我们主要复习如下内容：1．先行词与关系词2．限制性定语从句与非限制性定语从句3．关系代词的用法4．关系副词的用法5．定语从句需注意的事项6．初中阶段学习定语从句的要点二、专题梳理（一）什么是定语从句定语可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语等来充当，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。
定语从句在句中的作用相当于形容词，故又称为形容词性从句。
定语从句用来修饰名词、代词或整个主句。
gets first in his class.汤姆是一个用功的学生，他在班里总是第一名。
（修饰名词student。
）Football is played over 80popular.80多个国家都在踢足球，因此足球很流行。
（修饰整个主句Football is playedover 80 countries。
）（二）先行词与关系词1．什么是先行词：被定语从句修饰的名词、代词称为先行词。
可以这样理解，之所以称它为先行词，是因为先行词总是出现在定语从句之前，而不同于普通形容词修饰名词，形容词常位于名词之前。
bring.别忘了我让你带的书。
（the book为先行词。
）2．先行词与关系词的关系：引导定语从句的词被称为关系词。
关系词根据其在定语从句中的功能可分为关系代词和关系副词。
关系代词在定语从句中作主语、宾语、表语、定语等，关系副词在定语从句中作状语。
含有定语从句的句子一般分为两层：即主句层（第一层），定语从句层（第二层）。
特别提示：①关系词一般紧跟在先行词之后引导定语从句。
定语从句总在被修饰的先行词后面。
(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。
初中英语语法专题—定语从句讲解
初中英语语法专题—定语从句讲解一、什么是定语从句？定语从句是用来修饰名词或代词的从句。
它通常紧跟在被修饰的名词或代词后面，并对其进行进一步的说明或限制。
二、引导定语从句的关系词引导定语从句的关系词主要有：that, which, who, whom, whose, when, where等。
- that用于修饰物，常用来引导限制性定语从句；- which用于修饰物，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；- who用于修饰人，常用来引导限制性定语从句；- whom用于修饰人，在非正式情况下，常省略为who，也可以引导非限制性定语从句；- whose表示所属关系，修饰人或物；- when表示时间，在定语从句中用来引导时间状语从句；- where表示地点，在定语从句中用来引导地点状语从句。

初中英语定语从句语法详解
初中英语定语从句语法详解初中英语定语从句语法详解(名师剖析语法知识点+ 实战训练题，值得下载打印)定语从句是一种形容词的关系从句。
它由关系代词或关系副词引导（1）。
初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。
一、英语中的定语从句与汉语中的定语位置不同。
在复合句中，修饰某一名词或代词的从句叫做定语从句。
英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。
如：The man who / that I saw at the school gate yesterday is my English teacher.先行词定语从句昨天我在校门口看见的那个人是我的英语老师。
二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。
被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。
限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。
关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。
关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。
如：I am waiting for the boy who /that is wearing a red coat. （主语）先行词关系代词我正在等穿着红色外套的那个男孩。
The dictionary that / which my sister gave me last Sunday is very expensive.(宾语)先行词关系代词我姐姐上周星期天给我的那本字典很贵。

定语从句的基本结构为：关系代词/关系副词 + 句子。

二、关系代词和关系副词的使用1. 关系代词的使用（1）that：用于修饰人或物，可用于限制性定语从句和非限制性定语从句。
例如，The book that I borrowed from the library is very interesting.（我从图书馆借的那本书非常有趣。
）（2）which：用于修饰物，可用于限制性定语从句和非限制性定语从句。
例如，The car which is parked outside is mine.（停在外面的那辆车是我的。
）（3）who：用于修饰人，只能用于非限制性定语从句。
例如，Tom, who is my best friend, is coming to visit me tomorrow.（汤姆，我的最好朋友，明天要来看我。
）（4）whom：用于修饰人，只能用于非限制性定语从句，作为宾语时常常被省略。
例如，The girl whom I met yesterday is a famous singer.（我昨天遇到的那个女孩是一位著名的歌手。

中考定语从句知识点详细!
在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
【定语从句】一、定语从句概念定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。
定语一般是由形容词充当，所以定语从句又称作形容词从句。
另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。
定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。
请看示例：The woman who lives next door is a teacher.先行词定语从句在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。
二、关系代词引导的定语从句关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。
常见的关系代词有：who, that, which。
它们的主格、宾格和所有格如下表所示：格先行词主格宾格所有格人who whom whose物which which whose of which人、物that that —（一）关系代词who, whom和 whose的用法who代替人，是主格，在定语从句中作主语。
例如：An architect is a person who designs buildings. 建筑师是设计房屋的人。
I will never forget the teacher who taught us chemistry in the first year o f my senior middle school. 我将永远不会忘记在高一时教我们化学的那位老师。
