高考英语语法复习定语从句讲义
定语从句定语从句的核心考点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 for the plan raise your hands，please.3.先行词：被定语从句修饰的词称为先行词。
先行词一般是名词和不定代词，如：some-，any-，every-和no-与-body，-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。
4.关系词：连接先行词与从句的词叫关系词。
关系代词：who，whom，which，that，whose，as等关系副词：when，where，why等5.确定关系词的步骤：(1)先找先行词，看先行词指的是什么。
(2)看关系词在从句中所充当的成分。
注意：先行词与关系词是等量关系。
(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。
There are many places we can visit (them) in China.6.在定语从句中，当先行词指物时，下列情况的关系词宜用that而不用which：(1)当先行词是序数词或形容词最高级或被序数词、形容词最高级修饰时。
(2)先行词被all，every，no，some，any，little，much，the only，the very，few等修饰时。
(3)先行词为all，much，little，none，few，something，anything等不定代词时。
(4)先行词中既有人又有物时。
He was looking pleasantly at the children and parcels that filled his bus.(5)先行词在主句中作表语时。

第二讲定语及定语从句[思维导图]Ⅰ.定语1．修饰或限定名词或代词的词、短语或从句被称为定语。
2．定语可由形容词、数词、形容词性物主代词、介词短语、非谓语动词或定语从句等充当。
3．定语有前置和后置两种情况，如短语结构、从句等作定语时，常置于被修饰词之后。
The beautiful girl is her daughter.(形容词和形容词性物主代词作前置定语)那个漂亮的女孩是她的女儿。
The building being repaired is our library.(非谓语动词作后置定语)正在修复的那幢楼是我们的图书馆。
Ⅱ.定语从句一、必须掌握的定语从句的3个概念及2种分类1．定语从句在复合句中，修饰名词或代词的从句叫作定语从句。
The boy who is reading needs the pen which you bought yesterday.那个在阅读的男孩需要你昨天买的钢笔。
(定语从句作后置定语)定语从句可以分为限制性定语从句和非限制性定语从句。
2．先行词：被定语从句所修饰的词或句子叫先行词，作先行词的可以是：(1)一个词(通常是名词，也可以是代词)This is the place which is worth visiting.这是值得参观的地方。
He laughs best who laughs last.谁笑到最后，谁笑得最好。
(2)一个短语Many life’s problems which were solved by asking family members，friends or colleagues are beyond the capability of the extended family to resolve.许多以前可以通过询问家庭成员、朋友或者同事就能解决的生活问题，是现在的大家庭无力解决的。
(3)一个分句The Greeks assumed that the structure of language had some connection with the process of thought，which took root in Europe longbefore people have realized how diverse languages could be.希腊人认为，语言结构和思维过程之间存在着某种联系。
这一观点是在人们尚未认识到语言的千差万别以前就早已在欧洲扎下了根。
(4)一个完整的句子I found an old man lying on the ground and I took him to hospital ina taxi immediately，which was why I was late that morning.我发现一个老人躺在马路上，我乘出租车立即把他送到了医院，这就是那天上午我迟到的原因。
3．关系词引导定语从句的词叫关系词。
关系词包括关系代词和关系副词。
关系词有三大作用：代指先行词，引导定语从句，在从句中作句子成分。
4．分类(1)限制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。
如果关系代词在限制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?你认识那个刚刚进来的女孩吗？The time when I first met Mr.White was a very difficult period of my life.我第一次遇见怀特先生的时候是一个我一生中非常困难的时期。
(2)非限制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。
非限制性定语从句一般不用that引导。
The old woman，who lives on her own, has a cat for company.这个老妇人一个人住，养了一只猫陪伴她。
He whispered to me the news，which was really amazing.他低声告诉我这个消息，它真令人惊叹。
二、正确使用关系词1．关系代词Those who are interested in the film can contact me.对该电影感兴趣的可与我联系。
My daughter，whose job requires her to do a lot of travelling，is always away from home.我的女儿总不在家，她的工作需要经常出差。
[名师指津] 关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
Tom is one of the engineers who are sent abroad.汤姆是被派往国外的工程师之一。
Tom is the only one of the engineers who has come up with the solution. 汤姆就是唯一提出解决方案的那位工程师。
2．两组关系词的区别(1)4种只用that而不用which的情况：①先行词是不定代词或者先行词被不定代词所修饰时，关系代词通常只用that。
Do you have anything that you want to say for yourself?你有什么要为自己说的吗？②先行词被序数词、形容词最高级，the only，the very，the last等修饰时，关系代词通常只用that，不用which。
This is one of the most exciting football games that I have ever seen.这是我见过的最激动人心的足球比赛之一。
This is the only thing that we can do now.这是我们现在唯一能做的事情。
③先行词既有人又有物时，关系代词只用that，不用which。
The scientist and his achievements that you told me about are admired by us all.我们所有人都钦佩你告诉我的那位科学家和他所取得的成就。
④当先行词在主句中作表语，而关系代词也作表语时。
Shanghai is no longer the city that it used to be.上海不再是过去的那座城市了。
(2)which与as引导非限制性定语从句的3点区别She married again，which was unexpected.她再婚了，这是始料未及的。
She married again，as we expected.正如我们预料的那样，她再婚了。
[名师指津] as引导限制性定语从句常用于下列句式：such＋名词＋as(像……一样的，像……之类的)；such(pron.)＋as(像……一样的，像……之类的)；the same＋名词＋as(和……同样的)。
We have found such materials as are used in their factory.我们已经找到了像他们工厂里用的那种材料。
I have the same book as he has.我和他有同样的书。
3．关系副词I still remember the day when I first came to Beijing.我还记得第一次来北京的那一天。
The Voice of China has set up a big stage for young people with a talent for music，where some have stood out among them.《中国好声音》为有音乐天赋的年轻人建立了一个大舞台，在这个舞台上一些人从中脱颖而出。
The reason why he failed in the ex am was that he didn’t study hard.他考试失败的原因是他学习不努力。
[名师指津] 当先行词为表示抽象地点的名词situation，case，stage，point等，且关系词在定语从句中作状语时，用关系副词where引导定语从句。
如果关系词在定语从句中作主语或宾语时则用关系代词which/that。
They have reached the point where they have to separate with each other. 他们已经到了必须分手的地步。
4．“介词＋关系词”引导的定语从句Recently，I bought an ancient vase，the price of which was very reasonable.最近，我买了一个古董花瓶，它的价格很合理。
He has ten cousins，the youngest of whom is very clever.他有十个表兄弟，最小的那个很聪明。

Lily might possibly come，in which case I’ll ask her.莉莉可能会来，要是那样的话我就去问她。
There is a big window in my room，from where I can see the railway station.我的房间有一个大窗户，透过它我可以看到火车站。
“缺什么，补什么”，准确选用关系词1．如果先行词指人，定语从句中缺少主语，限制性定语从句中用who/that；非限制性定语从句用who。
2．如果先行词指人，定语从句中缺少宾语，限制性定语从句中用who/that/whom；非限制性定语从句用whom。
3．如果先行词指物，定语从句中缺少主语或宾语，限制性定语从句中用which/that；非限制性定语从句用which。
4．如果先行词指时间或地点，定语从句中缺少时间状语或地点状语，定语从句中用when/where; 如果从句中缺少的是主语或宾语，则用that/which。
5．不论先行词指人还是物，只要关系词在定语从句中作定语就用whose。
6．如果先行词指人，“介词＋关系代词”引导的定语从句中的关系词用whom，如果先行词指物，“介词＋关系代词”引导的定语从句中的关系词用which。
