（一）定语从句的概念定语从句：一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。
在主句中充当定语成分。
被修饰的词叫先行词。
定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后。
定语从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。
因此，Handsome boy = the boy who is handsomeBeautiful flower = the flower which is beautiful被定语从句修饰的词叫先行词，引导定语从句的词叫关系词。
关系词可分为关系代词（who, whom, whose, which, that)和关系副词(when, where, why)关系词都充当从句的某个成分，它所替代的相应成分应省去。
在定语从句中，当who, which, that作主语时，谓语的单复数应与先行词保持一致。

②代替先行词。
③在定语从句中担当一个成分。
定语从句分为限制性定语从句和非限制性定语从句。
非限制性定语从句与先行词的关系不如限制性定语从句与先行词的关系紧密，没有它，主句的意思也清楚，因此用逗号隔开。
关系词在非限制性定语从句中的用法与在限制性定语从句中的用法基本一样。

初中定语从句
定语从句一、定语从句一般是由关系代词（who，that，which，whose，whom）或关系副词（when，where，why）引导的。
eg：Do you know the man who came to see Xiao Yang this morning?At the time when I saw him, he was well.二、限定性定语从句和非限定性定语从句1.限定性定语从句修饰的词代表一个或一类特定的人或东西，如果去掉了定语从句，剩下的部分就会失去意义，不能成立或意思不清，或不能说明问题。
2.非限定性定语从句，支队所修饰的词作进一步说明，去掉之后其他部分仍可成立。
关系词前有逗号。
eg: Those who want to go please sign their names here.The letter that I received from him yesterday is very important.The students ho went to see the film were very disappointed.eg: She was very fond of speaking French, which indeed she spoke well.I have many friends, some of whom are paints.三、关系词的选择1.限定性定语从句，如果修饰人关系词多用who，that，当关系词在从句中作宾语用whom，who.eg：The people who you were taking to were Swedes.The people that you were taking to were Swedes.The people whom you were taking to were Swedes.2.如果定语从句修饰物，用关系代词that 或which.eg: The parcel that came just now was for me.The parcel whichcame just now was for me.3.关系词在介词之后只能用which.eg : The tool with which he is working is called a wrench.The tool which he is working with is called a wrench.4.当限定性定语从句修饰的是时间，常用关系副词when来引导从句，也可不用关系词或用that。
初中英语知识点：定语从句
中考英语定语从句讲解一、定义：在复合句中，修饰某一名词或代词的从句叫做定语从句；被定语从句所修饰的词叫做先行词。
如：1) The man who lives next to us is a policeman. 2) You must do everything that I do.引导定语从句的词：关系代词that, which, who(宾格who, 所有格whose) 关系副词where, when、why 关系词的作用：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单词作定语时通常放在它所修饰的词之前，作前置定语。
短语和从句作定语时则放在所修饰的词之后，作后置定语。
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。
