例如： The man who is shaking hands with my father is a policeman.该句中，who is shaking hands with my father 是定语从句，修饰先行词 the man ，“ who”是引导定语从句的关系词，代替先行词 the man ，在定语从句中作主语。
二:限制性定语从句和非限制性定语从句限制性定语从句形式上：不用逗号“，”与主句隔开。
意义上：是先行词不可缺少的定语，如删除，主句则失去意义或意思表达不完整。
译法上：译成先行词的定语：“．．．的”关系词的使用上： A ．作宾语时可省略 B ．可用 that C ．可用 who 代替 whom非限制性定语从句形式上：用逗号“，”与主句隔开。
意义上：只是对先行词的补充说明，如删除，主句仍能表达完整的意思。
译法上：通常译成主句的并列句。

被修饰的名词或代词叫先行词。
定语从句一般放在先行词的后面。
2 定语从句的关系词引导定语从句的关系词有关系代词和关系副词。
常见的关系代词包括that ，which ，who （宾格whom，所有格whose ），as 等。

*限制性定语从句1)大多数定语从句对所修饰词的意思加以限制,表示“…的人(或东西),称为限制性定语从句( Defining Attributive Clauses),如The man who robbed him has been arrested.抢劫他的人被速捕了。
The girl whom I saw told me to come back today我见到的那个姑娘叫我今天再来。
2)这类从句多由关系代词或关系副词引导a. Everyone who(that) knew him liked him. 认识他的人都喜欢他。
The friend with whom I was traveling spoke French.和我一道旅行的那位朋友能讲法语。
*非限制性定语从句1)非限制性定语从句( Non-defining Attributive Clauses)对所修饰的词没有限制词义的作用,而只是补充一些说明,通常都有一个逗号把它和句子的其他部分分开,在译成中文时,这个从句多译成一个并列句。
限制性定语从句拿掉以后,句子意思常发生变化,甚至不能成立,而非限制性定语从句拿掉以后对剩下部分没有太大的影响。

定语从句讲解(完整版)
定语从句讲解(完整版)定语从句是一种常见的语法结构，用于对名词或代词进行修饰和限定。
在英语中，定语从句的使用可以使句子更加丰富和准确。
下面，我将为您详细讲解定语从句的构成、用法和注意事项。
一、定语从句的构成定语从句由引导词、关系词和从句组成。
引导词通常是先行词，即被修饰的名词或代词；关系词用于引导定语从句，并将先行词与从句连接起来；从句则是对先行词进行修饰和限定的部分。
1. 引导词：先行词通常是名词或代词，它可以是主语、宾语或表语。
例如：The book that you gave me is very interesting.（你给我的那本书很有趣。
）The man who is talking to the teacher is my father.（正在和老师交谈的那个人是我的父亲。
）2. 关系词：关系词用于引导定语从句，并将先行词与从句连接起来。
关系词有who、which、that、whom、whose等。
例如： The book that you gave me is very interesting.（你给我的那本书很有趣。
）The man who is talking to the teacher is my father.（正在和老师交谈的那个人是我的父亲。
）3. 从句：从句是对先行词进行修饰和限定的部分。
从句中通常包含主语、谓语和宾语等成分。
例如：那本书很有趣。
）The man who is talking to the teacher is my father.（正在和老师交谈的那个人是我的父亲。
）二、定语从句的用法1. 限定性定语从句：限定性定语从句对先行词起到限定作用，即只有满足定语从句条件的名词或代词才是先行词的准确含义。
限定性定语从句通常紧跟在先行词之后，且不能用逗号与主句隔开。
例如： The book that you gave me is very interesting.（你给我的那本书很有趣。

非限制性定语从句
1. 非限制性定语从句的定义
非限制性定语从句是对被修饰部分进行附加说明，如果 去掉，主句的意思仍然完整或清楚。它和主句之间的关 系比较松散，因此常用逗号隔开。

人教版高一英语定语从句全面讲解与练习
定语从句定语：定语用来限定、修饰名词或代词的,是对名词或代词起修饰、限定作用的词、短语或句子,汉语中常用‘……的’表示;例如 a clever boy the boiling water fallen leaves•The boy in the classroom needs a pen.•The man standing there is my teacher.定语从句：一个句子充当定语The boy who is reading needs the pen.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;Ⅰ. 概念：1 定语从句：在主从复合句中用作定语的从句叫定语从句;定语从句一般紧接在先行词后面;2 先行词：被定语从句修饰的成份;先行词可以为一个词,短语,或整个主句;3 关系词：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;分为关系代词和关系副词;4 定语从句基本构成：先行词+关系词+从句A 关系词的作用：1 引导定语从句,连接主句和从句,相当于一个连词；2 必在从句中作某个句子成份可以做主语,宾语,表语,定语,状语1.The student who answered the question was John.2. I know the reason why he was so angry.3. The boy whom you are talking to is my brother.4. I’d like a room whose window looks out over the sea.B简单句变定语从句例1：The girl is Mary. The girl is standing there.The girl who is standing there is Mary.如何改写定语从句1、找准主句和从句,并找出两个简单句的共有成分,确定先行词;2、将从句中的共有成分去掉;3.找准关系词,用关系词引导从句剩下的部分,并紧接在被修饰词先行词之后;例2：A plane is a machine. The machine can fly.例3：The girl is Mary. We saw her yesterday.C定语从句选择关系词三步曲：第一找出先行词；第二看先行词在定语从句中的语法功能做主语、宾语或状语；第三选择合适的关系词;Ⅱ. 几个关系代词的基本用法：●that: 可指人或物；在定语从句中作主语,宾语,表语;指人时,相当于who或whom；指物时,相当于which 一般不用于非限制性定语从句; 不可置于介词后作宾语如：1. A letter that/which is written in pencil is difficult to read. 主语2. Do you know the gentleman that/who spoke just now3. You can take anything that you like. 宾语4. What is the question that/which they are talking about5. Here is the man who/whom/that you want to see.●which: 指物；在定语从句中作主语,宾语如：1. The book which/that was on the desk was bought by my father.主语2. The book which/that I bought yesterday is very interesting.宾语3. He was proud, which his brother never was. 表语●who, whom, whose:who: 主格, 在从句中作主语,在口语或非正式用法中作宾语; 只可指人whom: 宾格,在从句中作宾语; 只可指人whose: 属格,在从句中作定语,可指人也可指物;I like the students who/that work hard. 主语All who heard the story were amazed. 代词如he, they, any, those, all, one等后多用who.He's a man from whom we should learn. 宾语= He's a man whom/who/that we should learn from.A child whose parents are dead is called an orphan.指人I'd like a room whose window faces south. 指物whose +n. =the +n. + of which 物= of which 物+ the +n.=I'd like a room of which the window faces south. whose + n. =the +n. + of whom人= of whom人+ the +n.=I'd like a room the window of which faces south.注意：定语从句中的谓语动词的单复数于先行词保持一致This is one of the best books that have ever been written.He is one of the students who study hard at school.当one前面有the only等限定词和修饰语时, 定语从句的谓语动词要与one保持一致而取单数形式例如This is the only one of the best books that has ever been written.He is the only one of the students who studies hard at school.Ⅲ. 几个易混淆的关系代词的比较:●宜用that, 而不宜用which 的情况.①先行词为不定代词表示物,all, much, something, everything, anything ,nothing, none, the one等,②先行词被only, any, few, little, no, just, very, one of等词修饰时;③先行词是序数词时或被序数词修饰时;④先行词是最高级或被最高级修饰时;.⑤先行词既有人又有物,用which和who都不适合,这时宜用that. 如：⑧主句是There be 结构,修饰其主句的定语从句宜用that 作关系代词. 如：1. There is still a seat in the corner that is still free.⑨被修饰成分为表语时,或者关系代词本身是定语从句的表语时,该关系代词宜用that .2. My home village is no longer the place that it used to be .●定语从句中宜用which而不宜用that 的情况:①当关系代词的前面有介词时.1.A zoo is a park in which many kinds of animals are kept for exhibition.②在非限制性定语从句中.1.Crusoe's dog, which was are now very old, became ill and died .2.More and more people are beginning to learn English, which is becoming very popular in our country. which 指代主句B who & that:● who 和that 指代人时,有些情况宜用who, 而不宜用that①先行词为anyone, anybody, those, all, one, ones, they, he, people时. 如：.②在There be 结构中,修饰主语的定语从句宜用关系代词who 指代人. 如：1.There is a gentleman who wants to see you .Ⅳ.关系副词引导的定语从句:●When 指时间,在定语从句中作时间状语;定语从句中when=in/on/at which, 其先行词是表时间的名词如：time, day, week, tear, month, etc.I still remember the day when /on which my brother joined the army.作状语I shall never forget the day when Shen Zhou Ⅴwas launched, which has a great effect on my life.I still remember the days which/that we spent together. 作宾语Next winter which/that you'll spend in Harbin, I'm sure, will be exciting.●Where 指地点,在定语从句中作地点状语;定语从句中where=in/on/at which,其先行词是表示地点的名词,如：place, school, factory, room, etc.This is the factory where /in which he worked last year. 作状语This is the place where I was born.This is the park which/that they visited last year. 作宾语I live in the room which was bought by my father.I think you have got to the point where a change is needed, or you would fail.He's got himself into a dangerous situation where he's likely to lose control of the plane.●Why 指原因,在定语从句中作原因状语;先行词为reason 时,可用for which指代；如：That’s the reason why/for which he was late.The reason why / for which he didn't attend the meeting was that he was ill.I don't believe the reason that/which he gave me. 作宾语Have you asked him the reason t hat may explain his success 作主语当先行词为way时,关系词在句中作状语时,定语从句常用that, in which引导,that常可以省略;way后的定语从句的引导词不用时较多;但如果关系词在句中作主语或宾语时,则用which或that 引导;如:This is the way that /in which I do such things.比较: Please do the experiment in the waythat/whichI have shown you.V.介词+关系代词考点1.基本考点考点1 简单介词+关系代词引导定语从句时,that和who不能用于介词之后,能用于介词＋关系代词引导定语从句的代词只有which和whom;考查“介词+ 关系代词”引导的定语从句,关系代词前该选什么样的介词,要根据不同的语境、词组搭配、习语、惯用法等来决定,归纳起来介词的选择主要依据如下几点：①介词与定语从句的先行词搭配;如：The farm on which I once worked has taken on a new look．on the farm②介词与从句中动词搭配;如：Who is the man with whom our teacher is shaking hands shake hands with sb.In the dark street there wasn’t a single person to whom she could turn for help. turn to sb. for help③介词与定语从句中的形容词搭配,如：The west lake, for which Hang Zhou is famous, is a beautiful place. be famous for④根据句子的意思来决定, 此时不但要注意其前的搭配也要注意其后的搭配;Water is very important for us without which we can’t live.2004辽宁The factory produces half a million pairs of shoes every year, 80% of which are sold abroad．2006辽宁I was told that there were about 50 foreign students studying Chinese in the school, most of whom were from Germany.The old man has two daughters．Both of them are doctors．那位老人有两个女儿,她们都是医生;③as 常用在as we all know；as you know; as is known to all; as you see; as we can see; as has been expected 等结构中;例如：一般译为"正如""就像","这一点"As we all know, smoking is harmful to one's health . as 作宾语=As is known to all, smoking is harmful to one's health . as 作主语=It's known to all that smoking is harmful to one's health .=Smoking is harmful to one's health, as we all know .as 作宾语Jack has won the first prize, as often happens. 像往常一样,Jack得了一等奖;训练题汇总◆EX1用适当的关系词填空.1.
