定语从句一．定语从句的定义：所谓定语从句，就是用一个句子来做定语来修饰一个名词，其中被修饰的名词叫做先行词，连接先行词和从句之间（或者说引导定语从句）的词语叫做关系词，关系词分为关系代词和关系副词。
其中常见的关系代词有：that,which,who,whom,whose,as,but,than;常见的关系副词有：why,when,where.（注意：what，how，whether，if和特殊疑问词+ever不能引导定语从句）。
二．如何选择定语从句的连接词：首先明确先行词是什么，然后找到后面的从句，把从句单独拿出来分析，看一看先行词在句子中做什么成分，根据语法选择连接词。
Eg:He tried to escape from the prison that/which was builtin the Middle Age .分析：1.找先行词：prison 2.把prison放入从句中可以看到prison在从句中是做主语，即the prison was built in the Middle Age .而在定语从句中能充当主语的连接词一般情况下是that和which，于是就能选出连接词了。
三．连接词的用法：1.that：可以修饰人和物，在从句中作主语或宾语,表语，做宾语的时候一般情况下可以省略。
Eg: She is a girl who/that has long hair.(在从句中做主语) Is this the news (that)/which you wanted to tell me yesterday?(在从句中做宾语，可以省略that)He is no longer a kind-hearted man that he used to be(在从句中做表语)注意：1）that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：His father died in the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。

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。
定语从句一、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。
told him all (that) I know.gave her everything (that) he had.2.先行词被all, every, any, the very, the only, the just等修饰时。

定语从句一、定语从句及相关概念1、定语从句（The Attributive Clause)：在句中作定语，修饰某一名词或代词(甚至整个主句)的从句。
Mary is a beautiful girl 形容词作定语Mary is a girl （who has long hair）.The girl (whom I met) is Lucy.The school (where I study) is far from my home.I still remember the day（when I came here）.句子作定语, 叫做定语从句2、先行词（Antecedent)：被定语从句所修饰的名词或代词或句子.3、关系词(Relatives)引导定语从句的词，并代替先行词在从句中担任一定的成分二、定语从句中关系词及其作用，定语从句关系词分两类：1 Relative Pronouns（关系代词）:who , whom, which, that, whose, as2 Relative Adverbs（关系副词）:when, where, why关系词的作用：1、指代作用：指代先行词；2、连接作用：连接主从句；3、成分作用：在从句中充当成分The man who lives next to us sells vegetables.I’ll never forget the days which we spent together.This is the house where I lived two years ago.Do you know the reason why she was late.1 .The man who came to our school is Mr. Wang.（主语）2.

The computer____ they use belongs to the school.5.The school ____ is five meters away will be rebuilt.6. I will never forget the days____ we studied together.四．限制性定语从句和非限制性定语从句1限制性定语从句对先行词起修饰限定作用,常和先行词紧密相连2 而非限制性定语从句是对先行词起补充说明作用, 非限制性定语从句中，先行词与定语从句往往有逗号隔开,非限制性定语从句相当于并列句、状语从句, 非限制性定语从句不能用that来引导, 非限制性定语从句常常用来修饰整个句子如：I want to see this man, who can speak English.He gave up the plan, which was a very good one.I met John, who told me the news.I will take this one, which seems to be the best one.He has two sons, who work in the same company.He has two sons who work in the same company.教师评价: 批阅日期。
