定语从句1、功能：=形容词，修饰名词或代词，在句中作定语一：先行词：被定语从句所修饰的词二：关系词：用来连接定语从句，并在从句中代表先行词。
在从句中充当的成分：主语、宾语学会找关系词，看先行词指的是什么-----先行词，看关系词在从句中所充当的成分。
2、一般用法先行词是物：which that先行词是人：who whom that关系代词在从句中作宾语时可以省略。
e.g. The young man ( whom ) you saw was our manager.There is something ( that ) we must keep in mind.限制性定语从句与非限制性定语从句（逗号隔开非限制）1)限制性定语从句：从句与主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。
e.g. I was the only person in our office who was invited.（去掉定语从句，意思就不完整）2)非限制性定语从句：从句对先行词关系不密切，去掉定从句，意思仍然完整。
形式上用逗号隔开，不能that用引导。

There are about 400 students in our grade,most of whom are from Haidian District.10.关系副词：作时间状语：when=at/in/on/during which作地点状语：where=in/at/to/on which作原因状语：why=for which辨析The reason why.../The reason that.../The reason is that...The reason why...中why引导的是定语从句,why在句子中作原因状语,可以替换成for which;The reason that...中that引导的是同位语从句,that不作成分,that后面的内容说明reason的内容;The reason is that...是that引导的表语从句,不能用because,以免重复;五、其他1.主谓一致：从句中的谓语动词要和先行词的单复数保持一致;在“the one of + 复数名词”结构中,定语从句中的谓语动词常用复数形式;但是在the one of +复数形式或the only one of +复数名词结构中,定语从句的谓语动词用单数形式;2.关系词的省略与不可省略：关系代词在定语从句中作动词的宾语,表语时可以省略关系代词在定语从句中作介词的宾语,且介词在从句句尾时非限制性定从中的关系代词不可省略介词+关系代词中的关系代词不可省略表示时间的名词后关系副词可以省略,如the time,the moment表示地点名词后关系副词可以省略,如the place先行词the reason后面的关系副词可以省略先行词为way方法,手段时,关系副词可以省略3.如何判断定语从句和同位语从句根据that在从句中是否作成分来判断：that在定语从句中担任成分,在同位语从句中不做成分;The newsthathe told me yesterday is not true.The news that he singer will come here is not true.根据意思来判断：在引导词前加is后,如果句子成立就是同位语从句,否则是定语从句;The news is that he told me yesterday.句子不成立The news is that the singer will come here.句子成立4.定语从句转变为ing和ed形式直接转化为ing或ed形式,,去掉定语从句中who/which is/was/are/were.The boy who is playing the piano is from London.I like this film,which was directed by Zhang Yimou.将句子中的动词进行ing形式转化①The number of people who learn Chinese rises each year.=The number of people learning Chinese rises each year.②My grandfather,who hasn’t been used to living in the city,has decided to settle in the country.=My grandfather,not having been used to living in the city,has decided to settle in the country.=Not having been used to living in the city, my grandfather has decided to settle in the country.。

定语从句知识点梳理1.定语从句：定语从句是由关系代词或关系副词引导的从句，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。
2.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。
关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。

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。
1）who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下：Is he the man who/that wants to see you?他就是你想见的人吗？（who/that在从句中作主语）He is the man whom/ that I saw yesterday.他就是我昨天见的那个人。
（whom/that在从句中作宾语）2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 如：They rushed over to help the man whose car had broken down.Please pass me the book whose (of which) cover is green.3）which, that它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：A prosperity which / that had never been seen before appears in the countryside.The package (which / that) you are carrying is about to come unwrapped.4) asAs用于先行词前有as, so, such, the same修饰的限制性定语从句.You can take as many books as you need.(二) 关系副词when, where, why（在句中作状语）1. when指时间，在定语从句中做时间状语(1) I still remember the day when I first came to the school.(2) The time when we got together finally came.2. where指地点，在定语从句中做地点状语(1) Shanghai is the city where I was born.(2) The house where I lived ten years ago has been pulled down.3. why指原因，在定语从句中做原因状语(1) Please tell me the reason why you missed the plane.(2) I don’t know the reason why he looks unhappy today.注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换(1) The reason why/ for which he refused the invitation is not clear,(2) From the year when/in which he was going to school he began to know what he wanted when hegrew up.注意：介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等(1) This is the watch which/that I am looking for. (T)(2) This is the watch for which I am looking. (F)2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose(1) The man with whom you talked is my friend. (T)(2) The man with that you talked is my friend. (F)3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词(1) He loved his parents deeply, both of whom are very kind to him.(2) In the basket there are quite many apples, some of which have gone bad.4. 介词后面的关系词不能省略。

高中英语定语从句语法精讲练习(带答案)
高中英语语法讲解——定语从句(名师精讲必考语法知识点+实战训练，建议下载练习)一、先行词、关系代词和关系副词1．先行词(antecedent)就是被定语从句所修饰的名词。
在英语中，定语从句跟在被修饰词之后，所以被修饰词就是“先行”的词。
eg. The lovely girl often helps the old lady.She lives next door to our school.→The lovely girl who lives next door to our school often helps the old lady.→The lovely girl often helps the old lady who lives next door to our school.The lovely girl often helps the old lady.You met her at school yesterday.→The lovely girl (whom)you met at school yesterday often helps the old lady.→The lovely girl often helps the old lady (whom) you met at school yesterday.2．连接定语从句，要用关系代词(relative pronoun)和关系副词(relative adverb)。
关系代词和关系副词与连接词不完全相同，因为它们除了连接主句和定语从句，还在定语从句中代替一定的成分。
eg. The book which I bought yesterday is very interesting.← The book is very interesting. I bought the book yesterday.I have visited the house where Andersen wrote The Emperor’s New Clothes.←I have visited the house. Andersen wrote The Emperor’s New C lothes in the house.二、关系代词1．who的先行词是“人”，在从句中代替主语。

高中英语---定语从句一定义及相关术语1．定语从句：修饰某一名词或代词的从句叫定语从句。
定语从句一般紧跟在它所修饰的词之后。
2．先行词：被定语从句修饰的词叫先行词。
3．关系词：引导定语从句的词叫关系词。
关系词有关系代词和关系副词。
关系代词有that, which, who, whom, whose, as等；关系副词有when, where, why等关系词在定语从句中有三大作用1. 连接作用——连接先行词和定语从句。
2. 替代作用——在定语从句中替代从句所修饰的先行词。
3. 成分作用——在定语从句中作主语、宾语、定语或状语。
The man who is shaking hands with my father is a policeman.二关系代词引导的定语从句引导定语从句的关系代词主要有who, whom, whose, which, that等。
它们分别代替前面的先行词，并在定语从句中作主语、宾语或定语。
1. who 指人，在定语从句中作主语。
That is the teacher who teaches us physics.2. whom 指人，在定语从句中做宾语，可省略，在口语或非正式文体中常可用who 来代替。
Li Ming is just the boy (whom) I want to see.3. which 指物，在定语从句中做主语或宾语，做宾语时常可省略。
Football is a game which is liked by most boys.4. that 指人时，相当于who 或whom；指物时，相当于which.。
在定语从句中作主语或宾语，作宾语时常可省略。
He is the man that/who lives next door.Where is the man (that/whom) I saw this morning? 、The season that/which comes after spring is summer.The dress (that/which) Ann bought doesn’t fit her very well.5. whose 指人、物皆可，与后面的名词有所属关系，在定语从句中做定语。
I visited a scientist whose name is known all over the country.注意：指物时，常用以下结构来代替：The house whose windows are broken is empty.=The house the windows of which are broken is empty.Do you like the book whose cover is yellow?=Do you like the book the cover of which is yellow?三“介词+关系代词”引导的定语从句关系代词在从句中作介词宾语时，可以跟介词一起放在从句与主句之间（that, who不可以），也可以把介词放在从句中有关动词的后面，使关系代词紧跟它所修饰的先行词。
The school (which/that) he once studied in is very famous.=The school in which he once studied is very famous.This is the boy (whom/who/that) I played tennis with yesterday.=This is the boy with whom I played tennis with yesterday.注意：1. 含有介词的短语动词一般不拆开，介词仍放在短语动词的后面。
如：look for, look after, take care of 等。
2. 介词后的关系代词不可用that和who，若介词放在关系代词前，关系代词指人时只可用whom指物时只可用which；关系代词是所有格时用whose。
The man with whom you talked just now is my neighbour.3. “介词+关系代词”前还可有some, any, none, all, both, neither, many, most, each, few等代词或者数词。
如：He loves his parents deeply, both of whom are very kind to him.四关系副词引导的定语从句引导定语从句的关系副词有when, where和why等。
when, where, why都在定语从句中作状语，在意义上相当于介词+which结构，分别代替表示时间、地点或原因的先行词。
1. when 指时间，在定语从句中作时间状语。
I still remember the day when I first came to this school.注意：关系副词引导的定语从句经常可以用“介词+关系代词”引导的定语从句来表示。
如：I’ll never forget the day when/on which I first met you.Great changes are taking place in the city where/in which they live.五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，如果去掉，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whomThe teacher told me that Tom was the only person that I could depend on.China is a country which has a long history.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，如果去掉，主句仍能表达完整的意思。
译法上：通常译成主句的并列句。
关系词的使用上：A．不可省略 B．不用that C．不可用who 代替whomHis mother, who loves him very much, is strict with him.I have been to Hangzhou, which is a very beautiful city.（一）限制性定语从句中只能用that 引导定语从句的情况1.先行词为all, much, little, something, everything, anything, nothing, none, few, the one等时。
Everything that he said was true. 他所说的一切都是真的。
2.当先行词被the very（恰恰，正好）, the only，any，few，little，no，all修饰时。
This is the very grammar book (that) I want to buy.3．当先行词是形容词最高级或被形容词最高级修饰时。
This is the best that has been used against pollution.4. 当先行词是序数词或被序数词修饰时。

Do you know the things and persons that they are talking about?7．先行词在定语从句中做表语,而关系代词在从句中也做表语时。
She is no longer the sweet girl (that) she used to be.He is not the man (that) he seems. 人不可貌相。
（二）关系代词as和which 引导的定语从句1. as 和which都可以在定语从句中做主语或宾语，代表前面整个句子。
如：He married her, as / which was natural. He is honest, as / which we can see.2. as 引导的非限制性定语从句可以放在主句之前、主句之后，甚至还可以分割主句。
which 引导的非限制性定语从句只可放在主句之后。
另外，as 常常有“正如、正像”的含义。
As is known to all, China is a developing country.John, as you know, is a famous writer.Zhang Hua has been to Paris more than ten times, which I don’t believe.注意：当主句和从句之间存在着逻辑上的因果关系时，关系词往往只用which。
如：Tom was late for school again and again, which made his teacher very angry.1. 当先行词受such, the same 修饰时，关系词常用as。
如：I’ve never heard such stories as he tells.（三）以the way为先行词的限制性定语从句常由in which或that引导，而且通常可以省略。
The way (that/in which) he answered the questions was surprising.（四）关系代词与关系副词的选择用关系代词还是关系副词引导定语从句要看关系词在定语从句中的作用（所担当的成分）。
