定语从句语法总结定语从句语法总结定语从句语法总结一．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.定语从句的位置：紧跟先行词（名词或代词）之后。
4.引导词：引导定语从句的词（包括关系代词和关系副词）。
（1）关系代词：thatwhowhomwhichas（2）关系副词：whenwherewhy5.引导词的位置：位于定语从句之前（先行词之后）。
【as除外】6.引导词的功能（作用）：（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（关系代词充当主语或宾语，关系副词充当状语）。
7.定语从句的类型：（1）限定性定语从句（主句和定语从句之间无逗号）。
①直接由引导词引导定语从句The man who you’re talking to is my friend.②由介词+关系代词（whomwhich）引导The man to whom you’re talking is my fr iend.I need a pen with which I can write a letter.=I need a piece of paper on which I can write a letter.介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。
例如：The man (whowhomthat)I talked about at the meeting is from Beijing University.=The man about whom I talked at the meeting is from Beijing University.The palace (whichthat)I often pay a visit to was built in the 17th century.=The palace to which I often pay a visit was built in the 17th century.（2）非限定性定语从句（主句和定语从句之间用逗号隔开）。
定语从句总结主讲：赵晓君在复合句中，修饰某一名词或代词的从句叫定语从句。
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。
一、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）等，关系副词包括where， when， why等。
关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。
二、定语从句的分类根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。
限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去，非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。
三、关系代词的用法1. that 既可以用于指人，也可以用于指物。
在从句中作主语或宾语，作主语时不可省略，作宾语可省略。
2.which用于指物，在句中作主语或宾语，作主语不可省略，作宾语可省略。
3.who， whom用于指人，who 用作主语，whom用作宾语。
在口语中，有时可用who 代替whom，也可省略。
注意：（1）当定语从句中含有介词，介词放在句末时，who， that， which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。
例如：This is the house in which we lived last year.这是我们去年居住的房子。
Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。
（2）含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。
例如：This is the person whom you are looking for. 这就是你要找的那个人。
（3）that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。
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。
定语从句知识点总结第1篇一、省去作主语的关系代词致错误：The changes have happened in the past few years make the city look even more beautiful.正：The changes that have happened in the past few years make the city look even more beautiful.误：Those want to visit the art exhibition sign your names，please.正：Those who want to visit the art exhibition sign your names，please.分析：关系代词在定语从句中作宾语时可以省，但作主语时不能省。
二、从句中使用多余的代词或副词致错误：The compositions we handed them in two weeks ago haven’t been marked yet.正：The compositions we handed in two we eks ago haven’t been marked yet.分析：从句中省去了作宾语的关系代词that或xxxch，应去掉them。
误：After living in Paris for 60 years，he returned to the small town where he grew up as a child there.正：After living in Paris for 60 years，he returned to the small town where he grew up as a child.分析：关系副词where在从句中作地点状语，xxxhere属语义重复，应去掉。
三、as / it / xxxch混用致错误：As is known to all that smoking does great harm to health.正：It is known to all that smoking does great harm to health.或As is known to all，smoking does great harm to health.分析：as引导非限制性定语从句，置于句首时，要用逗号与主句隔开;it放在句首，作形式主语时，将从句后置，中间不用逗号。
定语从句知识点总结详细一、定语从句的概念定语从句是一种对名词起修饰或限制作用的从句，它通常由关系词引导，用来进一步说明先行词的情况、属性或特征。

）三、定语从句的结构定语从句通常由关系代词或者关系副词引导，加上从句。
关系代词包括that, which, who, whom, whose等，关系副词有when, where, why等。

定语从句总结(精辟)1.定语从句: 1) 定语从句的定义在复合句中，修饰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先行词。
引导定语从句的词叫关系词。
关系词包括关系代词who(宾格whom,所有格whose),that, which 和关系副词where, when, why 等。
The boy who is wearing a black coat bought a dictionary yesterday.The noodles that（which）my mother cooked were delicious. The school where I learned judo was very large.I remember the day when our band was formed.I do n’t know the reason why she got so angry this morning.2) 定语从句的种类：定语从句可以分为限定性定语从句和非限定性定语从句。
(1)限定性定语从句：它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。
这种从句与主句的关系十分密切，书写时不可用逗号分开。
如果关系代词在限定性定语从句中作宾语，关系代词通常可以省略。
Do you know the girl who just came in?Shanghai is a city（that）I’ve always wanted to visit.Her sister married a man (who/whom/that) she met on a plane.The time when I first met Mr. White was a very difficult period of my life.(2)非限定性定语从句：它只是对先行词作附加补充说明，如果去掉，主句的意思仍然清楚完整。
这种从句与主句的关系不是很密切，书写时往往用逗号分开。
非限定性定语从句一般不用that 引导，而且不可以省略关系词。
The old woman, who lives on her own, has a cat for company. Lori is going to marry Mark, whom she does not love. Beijing, which is the capital city of China, is a very beautiful city.3) 关系代词的用法：在定语从句中，关系代词起着连接主句与从句，指代先行词和在从句中作句子成分的三重作用。
关系代词的选用取决于主句中的先行词以及关系代词在从句中作何种成分。
一．关系代词who, whom 的用法（1）who 可以代替人（即它的先行词必须是人），在从句中担任主语，往往也可以代替在从句中担任宾格的whom,但它的前面不能有介词，如果带介词则必须用宾格whom，即“介词+whom”. E.g. Jonny is a person who always has novel ideas.The girl who the first prize in the contest is from Zhejiang.The person who/whom you just talked to is Mr. Depp.---The person to whom you just talked is Mr. Depp. (介词to提到定语从句前，只能用whom.)We’ll go to the hospital to see the patients, most of whom are children.(whom 前常用表示数量的词none/neither/both/each/all of…)(2)在定语从句中，who, that 指人时可以通用，但在下列情况下用who,而不用that.A) 先行词是one, ones, anyone 时，宜用who.One who has nothing to fear for oneself dares to tell the truth. The ones who flatter me don’t please me. Anyone who laughs last laughs best.Anyone who fails to finish the task given should be criticized.B) 先行词为those 时，宜用who. Those who want to go to the Great Wall sign up here.No words are strong enough to express our thanks to those who worked hard to rescue survivors in the earthquake.C) 当先行词有较长的后置定语时，宜用who.I met a girl in the street yesterday who grew up in Yunnan province.D) 一个句子中带有两个定语从句时，其中一个定语从句的关系代词时that，另一个宜用who. E.g. The boy that you met last night is the group leader who studies very hard.E) 在there be 开头的句子中，事宜用who.There is a young man who wants to see your father. There was a king who was kind to his people.There are many old men who are against this plan.二．关系代词whose 的用法：关系代词whose 是关系代词who 的所有格形式，它既可以代人，也可以代物。
当whose 代物时，相当于of which. Whose 引导的定语从句既可以是限定性定语从句，也可以是非限定性定语从句。
Do you know Peter whose father happens to be working in your company?The tourist wanted to book a room whose window faces south. =The tourist wanted to book a room the window of which faces south.=The tourist wanted to book a room . The room’s window faces south.We went to see our teacher Miss Styles, whose husband lost his life in the earthquake.Xi’an, whose walls remain as good as before, is one of the few cities with city walls.三．关系代词that, which 的用法（1）在限定性定语从句中指代物时，which 和that 一般可通用。
The new house that/which I has just bought is about six miles away.They planted some trees that /which didn’t need much water.(2) 限定性定语从句中只用that 而不用which 的情况。
A）先行词有形容词最高级修饰时This is the best way that has been used against pollution.Polly is the most direct young woman that I have ever come across .B) 先行词有序数词修饰时This is the third time that they have met.The very first time that Lester saw the film, he made up his mind to become a doctor.C)主句已有疑问词who 或which 时Which of the car s that are in front of the hotel belongs to you? Who is the man that is sitting by the lake ?D) 先行词既有人又有物时He talked about the schools and teachers that he had visited. The bike and his rider that had run over an old man were taken to the police station.E) 先行词为all, much, few, little, something, everything, anything, nothing, none 等不定代词时It’s easy to do the repair. All that you need is a hammer andsome nails.We haven’t got much that we can offer you.I’d like to tell you something that will make you surprised.F) 先行词前面有the very, the only, the same, any, few, little, no, all, one of 等词修饰时This is the very room that I slept in that evening.The only thing that we can do is to give you some money.Li Ming is the only one that wants to be a teacher.G) 有两个定语从句，其中一个关系代词以用which,另一个宜用thatEdison built up a factory which produced things that had never been seen before.(3) 只用which 而不用that 的情况A) 引导非限定定语从句时The fish, which I bought this morning, is very fresh.My house, which I bought two years ago, has got a lovely garden.Jim passed the driving test, which surprised everybody in the office.Helen was much kinder to her youngest son than to others, which , of course, made the others envy him.The factory produces half a million pairs of shoes every year,most of which are sold abroad.(which 前常用none/neither/most/both/each/all/a little of等词修饰)B）在限定性定语从句中，关系带词前有介词时I was put in a position in which I had to accept I was less important.This is the hotel in which you will stay.= That’s the hotel (which/that) you will stay in.(此句中，如果介词in 放在句子的后面，那么关系代词既可用which,也可用that,还可省略。
