初三英语定语从句知识点
初三英语定语从句知识点一、定语从句的概念及基本用法定语从句是修饰一个名词或代词的从句，起到对这个名词或代词进行限定或说明的作用。
定语从句通常由关系代词或关系副词引导，对其前面的名词或代词进行修饰。
1. 关系代词引导的定语从句关系代词有who, whom, whose, which和that，它们在定语从句中用来代替句子的主语、宾语、所有格或宾语。
例如：The girl who is talking to Tom is my sister.正在和汤姆说话的那个女孩是我姐姐。
2. 关系副词引导的定语从句关系副词有where, when和why，它们在定语从句中用来代替地点、时间和原因。
例如：I still remember the day when we first met.我仍然记得我们第一次见面的那天。
二、定语从句的位置和引导词选择1. 定语从句通常紧跟在被修饰的名词或代词之后，修饰它。
例如：The book that I borrowed from the library is very interesting.我从图书馆借来的那本书很有趣。
2. 引导定语从句的关系词选择要根据被修饰的名词或代词在定语从句中的成分来确定。
a. 如果在定语从句中充当主语，则用关系代词who或which。
b. 如果在定语从句中充当宾语，则用关系代词whom或which。
c. 如果在定语从句中充当宾语，并且前面有介词，则用关系代词whom或which，介词与关系代词一起构成介词短语。
d. 如果在定语从句中充当定语，则用关系代词whose或which。
e. 如果在定语从句中充当状语，则用关系副词where、when或why。
例如：The man who/whom I met yesterday is a teacher.昨天我遇见的那个人是一位教师。
The book which/that is on the table is mine.在桌子上的那本书是我的。
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。
Anyone who wants to apply for this job must send us the resume by em ail first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。

关系代词在定语从句中做主语,宾语,定语,关系副词在定语从句中做状语.引导定语从句的关系代词有who,whose,whom,which,that,引导定语从句的关系副词有when,where,why;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是关系副词，用来表示地点的定语从句。
2.when引导定语从句表示时间四、限定性定语从句和非限定性定语从句的区别：限定性定语从句是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。
这种从句和主句的关系十分密切，写时不用逗号分开。
非限定性定语从句和主句的关系不十分密切，只是对先行词作些附加的说明，如果去掉，主句的意思依然清楚。
这种从句和主句之间往往用逗号分开，一般不用that引导。
五、.下面详细讲解各个关系代词的用法：1）由who引导的定语从句,who在从句中做主语(口语中也可做宾语),代替表示人的先行词.例如:This is the man who helped me.Do you know the man who spoke just now?The boy who/whom we saw yesterday is John’s brother.2）whom引导的定语从句,whom在从句中作宾语,代替表示人的先行词(口语中可以省略).The doctor(whom)you are looking for is in the room.The person(whom)you just talked to is Mr.Li.=The person to whom you just talked is Mr.Li.(介词后whom不能省略,也不能用that.)The babies whom the nurses are looking for are very healthy.(固定短语中的介词一般不省略,介词仍放在动词之后)3）.whose引导的定语从句,whose在从句中作定语,代替人或物的先行词.Do you know the woman whose name is Mary.Pass me the dictionary whose cover is black.4）.that引导的定语从句,代替表示人或物的先行词,that在从句中做主语或宾语,作宾语时可省略,不能放在介词后面作宾语.1.The letter(that//which)I received was from my father.2.I can’t find the letter that//which came this morning.3.Do you still remember the days(that//which)we spent together?4.This is the man that//who helped me.5.The house(that//which)we live in is not large.=The house in which we live is not large.6.The doctor(that//whom//who)you are looking for is in the room. 5）.which引导的定语从句,which代替表示物的先行词，在从句中做主语,也可做宾语,或介词的宾语,先行词可以是词、短语、句子。

中考英语 定语从句讲解
中考英语定语从句讲解定语从句定语从句是复合句中修饰名词或代词的句子。
被修饰的词叫先行词，引导定语从句的词叫关系词。
定语从句分为限定性和非限定性两种。
限定性定语从句是必不可少的，没有它，先行词的意思不明确，主句也不完整。
非限定性定语从句是对先行词的补充说明，没有它不会影响先行词或主句意思的完整性。
限定性定语从句与先行词之间不用逗号，非限定性定语从句一般用逗号同主句分开。
限定性定语从句的结构是先行词+关系词+从句。
关系代词有which。
who。
whom。
whose。
that，关系副词有where。
when。
why。
定语从句的实质是把两个句子合并为一个句子，保留先行词，舍去与先行词互指的词，用关系词代替舍去部分。
例如，将"I saw the man。
He closed the door."合并为一个句子可以得到"The man who/that I saw closed the door."。
关系词的选择要根据先行词的分类和在从句中充当的成分来确定。
如果先行词是人并在从句中做主语或宾语，可以用who/that或者whom/that；如果先行词是物并在从句中做主语或宾语，可以用which/that；如果先行词是人或物并在从句中做定语，可以用whose或者of which；如果先行词表示时间、地点或原因，可以用when。
where。
why。
总之，定语从句是复合句中一个重要的句型，掌握好定语从句的用法和结构可以帮助我们更好地表达自己的意思。
XXX man XXX。
They had planned to meet her and learn from her。
I know the XXX。
Practice:1.I have a XXX.2.XXX Emily was XXX I gave her.3.The man that broke his leg in a match used to be a football player.Note: That can be used instead of which in some cases。

e.g:Mr. Green，who is watching TV，is my uncle.（三）(限定性)定语从句的结构Mary is a girl who has long hair.先行词关系词定语从句关系代词关系副词which, who, whom,whose, that where, when, why（四）定语从句的实质：二句合一（合并条件：人物先行在句一，又占句二一席地）Mary is a girl.合并为一个句子She has long hair.思路：留（保留先行词）-----舍（舍去与先行词互指的词）----替（用关系词代替舍去部分）Mary is a girl who/that has long hair.请把下列句子二句合一1. I saw the man.He closed the door2.The girl is happy. She won the race3.The man called the police . His wallet was stolen（五）定语从句关系词的确定:● a.先行词的分类● b.先行词在从句中充当的成分1.先行词做主语人：who/that物：which/that2.先行词做宾语人：who/whom/that物：which/that3.先行词做定语人：whose物：whose/of which 4.先行词做状语：w h e n,w h e r e,w h y●who, whom, whose, that用法区别.●who /that作定语从句的主语或宾语.The man who/that is speaking at the meeting is a worker. 做题思路：先分解——分析——再合并●Whom /that作定语从句的宾语The woman（whom/that) they wanted to visit is a teacher.分解The woman is a teacher.注意: 关系代词作动词宾语时可省略.●whose 作定语从句的定语.I know the girl whose mother is a teacher.分解I know the girl.The girl’s mother is a teacher.小结：关系词判断步骤●首先，要辨别出先行词。
如果先行词是指人,关系词可能就用who, that whom, whose。
如果先行词指物,关系词可能用which或that●然后，要确定关系词在从句中的成分。
请看下表先行词主语宾语定语人who, that who(m), that whose物which,that which, that whose,of which巩固练习：用适当代关系词填空1. I have a friend ________ likes listening to classical music.2. Yesterday Emily was wearing the new dress __________ I gave her.3. The man ______ leg broke in a match used to be a football player.（六）只能用that,不能用which的情况：(1)先行词为all, everything，anything，nothing, something, nothing ,few, little, much, the one 等不定代词时；(2)先行词被形容词最高级所修饰或被the only, the very, the last, any, few, little , no, all, one of 等修饰时：(3)先行词为数词或被序数词（含last)修饰时。
（4）先行词是并列词组既有人又有物时。
(5)在以who, which开头的句子中为了避免重复。
口诀：不定代词这一伙，全用that准没错先行词前有修饰，千万不能用which.请在以下例句中体会以上规则：1. Here is something that I will tell you.2.We haven’t got much that we can offer you.3. Is it the one that you want ?4.This is the most interesting story that I have ever heard.5. I can remember well the persons and some pictures that I see.6.Which is the bike that you lost?7.Who is the woman that was praised at the meeting?（七）只能使用w h i c h的情况●1.关系代词前有介词时；●2.先行词本身是t h a t时；●3.非限定定语从句●口诀:要有w h i c h别着急，●介词提前逗隔离。
