（完整版）定语从句讲解总结定语从句讲解⼀．定语从句1.注意英汉差异：汉语的定语⽆论多长都放在被修饰词的前⾯，⽽英语中的定语则不然，是⼀个词时，放在被修饰词的前⾯，如：①.a beautiful girl ②.a lovely boy是两个以上的词组、短语或从句则放在被修饰词的后⾯，如：③.She is the girl in red. 她就是穿红⾐的⼥孩。
④.The lady carried a bag full of money. 那位⼥⼠背了个装满钱的包。
⑤.He is the man who you are looking for. 她就是你在找的⼈。
2.分清主句与从句，看究竟哪个句⼦缺少成分。
如上⾯第5：主句：He is the man从句：who you are looking for在从句中，looking for 的宾语是the man.因此选⽤关系代词 who(whom)放置于句⾸，便是定语从句。
3.从句中做宾语的关系代词可以省略，故第5题可以写成：He is the man you are looking for.⼆．定语从句（从句部分）1、功能：相当于形容词，修饰名词或代词，在句中作定语2、位置：定语从句置于被修饰词之后Those who are willing to attend the party, sign here please.3、先⾏词：被定语从句修饰的词称为先⾏词（1）先⾏词⼀般是名词和不定代词，如:some-, any-, every-和no与-boy, -thing的合成词；或all、none、any、some、that、those等代词。
数词也可以作先⾏词，⼈称代词也同样可作先⾏词。
（2）先⾏词与关系词是等量关系。
必须注意两点：①先⾏词在从句中作主语时，从句谓语动词的数由先⾏词⽽定。
This is the place which is worth visiting.②关系词在从句句⼦中充当了成分，其意思就是先⾏词的意义，所以在从句中不能重复其意。
定语从句一．几个基本概念1.定语从句的定义：用作定语的从句叫定语从句。
2.先行词：被定语从句所修饰的名词或代词。
3.关系词：引导定语从句的词（包括关系代词和关系副词）。
﹙1﹚关系代词：that/who/whom/which/as/whose﹙2﹚关系副词：when/where/why4.关系词的功能：﹙1﹚连接先行词和定语从句。
﹙2﹚在定语从句中充当一定的成分（关系代词充当主语、宾语或表语，关系副词充当状语）。
5.定语从句的类型：(限定性定语从句和非限定性定语从句)1.在形式上非限定性定语从句与主句有逗号隔开。
He always makes fun of me, which upsets me.2.非限定性定语从句的作用：它只是补充说明先行词的情况，翻译时可译成两个句子。
The engineer, whose leg was badly hurt, was quickly sent to hospital.（那位工程师被很快送往医院，其腿部受了重伤）The engineer whose leg was badly hurt was quickly sent to hospital.（那位腿部受了重伤的工程师被很快送往医院）二、关系代词1.who/that指人，作定语从句的主语，不能省略。
Do you know the gentleman who/that is sitting there?2.whom/who/that指人是宾格，作定语从句的宾语（动宾或介宾）。
①当作动宾（动词后接宾语）时，关系代词可省略。
Do you know the gentleman (whom/who/that) we met just now?②当作介宾（介词后接宾语）时：介词不提前时，关系代词可省略；介词提前时，关系代词不可省The man (whom/who/that) I spoke with is my teacher.The man with whom I spoke is my teacher.※注：固定的动词短语（动词+介词）如look for, take care of等不能把动词与介词拆开，既介词不能提至引导词前。
1一、定语从句概述定语可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语 等来担任，也可以由一个句子来担任。
在句子中起定语作用的从句称为定语 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。
被定 语从句修饰的名词叫先行词，引导定语从句的词叫关系词。
二 关系词的用法。
关系词可分为关系代词和关系副词。
关系词指代先行词，放在先行词与 定语从句之间起连接作用，同时又充当定语从句中的某一种成分（主语、宾 语、状语等）。
引导定语从句的关系代词有"at ，who ，whom ，whose ，which;关系副词有 when ，where ，why 等。
关系词在句子中的指代作用及成分如下表 1.关系代词的用法(1) who, whom 的用法二者都用于指人。
who 在定语从句中作主语、宾语;whom 在定语从句中 作宾语。
在现代英语里，有时who 也可代替whom 在从句中作宾语。
作 宾语的关系代词who ，whom 可以省略(介词后作宾语的关系代词除外）。
She was the one who did most of the talking 。
大部分时间都是她在说话。
（作主语） The boy who I know studies best in his class.我认识的那个男孩在班上学习最好。
（作宾语）I happened to meet the professor (who/whom) I got to know at a party. 我碰巧遇见了那位在一次聚会上认识的教授。
（作宾语，whom 可用who 代替) whom 在从句中作介词的宾语，且介词提到whom 前面时，不能用who 代替。
Yesterday I came across a few friends with whom I went to the park .昨天 我碰见了几个朋友，我和他们一起去了公园。

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。
定语从句总结-完整版一、定语从句：由关系代词who, whom, whose, that, which,as; 关系副词when, where, why 引导。
