定语从句(1)
定语从句一．定语从句的定义：所谓定语从句，就是用一个句子来做定语来修饰一个名词，其中被修饰的名词叫做先行词，连接先行词和从句之间（或者说引导定语从句）的词语叫做关系词，关系词分为关系代词和关系副词。
其中常见的关系代词有：that,which,who,whom,whose,as,but,than;常见的关系副词有：why,when,where.（注意：what，how，whether，if和特殊疑问词+ever不能引导定语从句）。
二．如何选择定语从句的连接词：首先明确先行词是什么，然后找到后面的从句，把从句单独拿出来分析，看一看先行词在句子中做什么成分，根据语法选择连接词。
Eg:He tried to escape from the prison that/which was builtin the Middle Age .分析：1.找先行词：prison 2.把prison放入从句中可以看到prison在从句中是做主语，即the prison was built in the Middle Age .而在定语从句中能充当主语的连接词一般情况下是that和which，于是就能选出连接词了。
三．连接词的用法：1.that：可以修饰人和物，在从句中作主语或宾语,表语，做宾语的时候一般情况下可以省略。
Eg: She is a girl who/that has long hair.(在从句中做主语) Is this the news (that)/which you wanted to tell me yesterday?(在从句中做宾语，可以省略that)He is no longer a kind-hearted man that he used to be(在从句中做表语)注意：1）that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：His father died in the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。

定语从句（一）--------关系代词的用法一．定语从句的概念在复合句中，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。
引导定语从句的词叫做关系词。
关系词有三个作用：1、引导定语从句;2、代替先行词；3、在定语从句中担当一个成分。
二、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，whom和whose，关系副词包括where，when，why等。
Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。
（that作主语）The coat （that）I put on the desk is blue.（that作宾语）The building which stands near the train station is a supermarket. （作主语）The film （which）we saw last night was wonderful. （作宾语）3. who指人在从句中做主语或宾语，作主语不可省略，作宾语可省略。
例如：The boys who are playing football are from Class One.翻译：指人，在定语从句中充当宾语，常用who代替，可省略。
例如：Mr. Ling is just the man whom I want to see.翻译：5..whose通常指人，也可指物，在定语从句中做定语(1) He has a friend whose father is a doctor.(2) I once lived in a house whose roof has fallen in.(3) The classroom whose door is broken will soon be repaired.(4) The classroom the door of which is broken will soon be repaired.(5) Do you like the book whose cover is yellow(6) Do you like the book the color of which is yellow2. 关系词只能用that的情况：a. 先行词被序数词或形容词最高级所修饰，或本身是序数词、基数词、形容词最高级时;例如：He was the first person that passed the exam. 他是第一个通过考试的人。

定语从句1
定语从句定语从句是初中语法中较难的一个知识点，同时也是近几年中考必考的。
一．定义：在复合句中修饰某一名词或代词的从句叫定语从句。
二．特点：1.先行词：定语从句所修饰的名词或代词 2. 关联词：1）引出定语从句，并作从句的一个成分。
可作主语、宾语、定语、状语，作宾语可省略。
2）关联词包括关系代词和关系副词。
关联词位于先行词和定语从句之间。
关系代词：that, which, who, whom, whose代指先行词。
关系副词：when, where, why作时间状语。
三．基本结构：先行词+关联词+定语从句剩余部分四．关系代词的用法：1. that 和whichthat指人或物，作主语或宾语，作宾语可省略，主语不能。
Which指物，不指人，作主语或宾语，作宾语可省略，主语不能。
His father works in a factory that/which makes TV sets.Who was hurt in the accident that/which happened yesterday?The coat (which/that) I put on the desk is black.注意：The room in which I live is very big. (在介词后面不能用that)2.只能用that不能用which引导的定语从句：1) 先行词被形容词最高级修饰时，定语从句只能用thatThis is the most interesting story (that) I have ever heard.2）先行词被序数词修饰时，定语从句只能用thatThe children like the second lesson that is about “The Football Match”.3）先行词被the only，the very 或the same等修饰，定语从句只能用that引导。
定语从句(1)
The reason why his sister was late is that her husband is dangerously ill in hospital.
句中why 不可用that 代替，以避免重复；that 不能用because 或why 替代。陈述句主语 reason 的表语从句中只能用that 引导，that 不做从句中的任何成份。
• as与which • as引导的定语从句可以放在主句之前，之中或其后； which引导的定语从句只能放在主句之后。 • as一般用于一些固定句型中，有“正如”之意。 如be said/reported/expected/known/imagined/pointed out/shown/announced等被动形式，或as you see/hear/know等结构中。 • Eg: As is said, they will send us to help the children in the less-developed areas. • 据说，他们要派我们去帮助那些欠发达地区的儿 童。 • She did well in her studies, which made her parents satisfied. • 她学习很好，这使她父母很满意。
专有名词具有“独一无二”的含义，因 此通常用非限制性定语从句来修饰。
Hangzhou, which we visited last year, is one of the most beautiful cities in China.
that 不能引导非限制性定语从句。其他引导限制 性定语从句的关系代词、关系副词皆可引导非限 制性定语从句，且不可省略。
当 the same修饰先行词时，引导定语从句 的关系代词可用as, 或that。用that表示他所 引导的内容与先行词所讲的事物是同一个； 用as表示“同类”。 This is the same bicycle that I have lost. 这是我丢失的那辆自行车。 This is the same bicycle as I have lost. 这辆自行车跟我丢的那辆一样。
定语从句(1)(that,which,who,who,whose)
注意：在“one of +复数名词+定语从句”结构中，复数名词是先行词， 引导词在定语从句中作主语时，其谓语动词用复数。但当one前有the (only)时，one是先行词，定语从句的谓语动词用单数。如：
He is one of the students who have been to Beijing. 他是去过北京的 学生之一。
1. the most important thing _____we should pay attention to is the first thing____ I have said. 2. He never reads anything _____is not worth reading. 3.

定语从句1
定语从句定语从句功能及位置功能：定语从句相当于形容词，修饰名词或代词，在句中作定语。
位置：定语从句置于被修饰词之后。
例：Those who are willing to attend the party , sign your names here please. 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，一般跟在它所修饰的先行词后面。
(定语从句的概念:在复合句中,修饰某一名词或代词的从句叫做定语从句.被修饰的名词或代词叫做先行词,定语从句一般放在先行词的后面.）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，绝对没有what；关系副词有where, when, why,how等。
关系词常有3个作用：①连接作用，引导定语从句。
②代替主句中的先行词，甚至可能是主句中的一部分或者整个主句。
③在定语从句中充当一句子成分。
注：关系代词有主语、宾语之分。
一般whom作为宾语。
关系代词在从句中作主语，宾语，表语，定语等，关系副词在从句中作地点状语，时间状语，原因状语等。
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（动词不定式短语、动名词短语和分词短语）或句子，汉语中常用‘……的’表示。
主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任。
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。
先行词被定语从句修饰的名词、代词称为先行词。
如The man The book关系代词引导的定语从句举例关系代词所代替的先行词是人或物的名词或代词，并在从句中充当主语、宾语、定语等成分。
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。

三、关系词只能用that而不用which的情况
1．当先行词为all, everything, nothing, anything, much等不 定代词时。 Have you taken down everything that Mr. Li said? All that can be done has been done.
2．高考对简单句、并列句和各种复合句的考查 常表现在对连词的选择和使用上。如：and, but, or, while 以及其他连接名词性从句、定语从句和状语从句 的连接词、关联词。

定语从句一、定语从句与引导词定语从句是在复合句中修饰某一名词或代词的从句。
被修饰的名词或代词叫做先行词，而引导定语从句的词叫引导词，有关系代词和关系副词两类。
懂得什么样的先行词后用什么样的引导词是学好定语从句的关键。
1．关系代词有：that, which, who, whom, whose, 在定语从句中作主语、宾语、表语，whose作定语。
代人的有：who, whom, whose, that；代物的有：that, which, whose. 例如：The man who helped you is Mr White. (who代人，在定语从句中作主语)That is the person (whom/who/that) you want to see. (whom, who, that代人，在定语从句中作宾语，可省略)I’m not the fool (that) you thought me to be. (that代人，在定从中作表语)A dictionary is a useful book which(＝that) tells us the meaning of words(which或that代物，在定从中作主语)2．关系副词有：when(指时间)，where(指地点),why(指原因)，在定语从句中作状语。
例如：Would you suggest a time(when) we can have a talk?(when可省略)The house where they live is not very large./This is the reason why he did not came to the meeting.注意：不是表时间的先行词都用when引导定从，不是表地点的先行词都用where引导定从。
例如：We’ll visit the factory which(＝that) makes radios.(which或that在定从中作主语，where不可用主语，故不可用)They still remember the happy days (which/that) they spent in Beidaihe.(which或that在定从中作spent的宾语，when不可作宾语，故不可用)二、限制性定语从句与非限制性定语从句限制性定语从句和主句之间不用逗号分开，修饰主句中的某一个名词或名词词组或代词；非限制性定语从句常用逗号和主句隔开，可以修饰主句中的某一个词，也可修饰整个句子。
非限制性定语从句不能用that引导，引导非限制性定语从句的关系词不能省略。
非限制性定语从句例：Li Ping’s father, who works in a factory, is an engineer.He tore up my photo, which made me very angry.(which指代主句内容，因前后两句是因果关系，此时which不可换为as。
)He is good at physics, as is known to us all.＝As is known to us all, he is good at physics.(as指代主句内容，在as is known/believed, as we all know/believe这类结构中as不可换为which)三、that 和which 用法的区别首先，that和which在从句里都可以做宾语和主语，做宾语时可以省略。
在定语从句中,有种说法叫"关宾省",意思是关系代词在限制性定语从句中作宾语可以省略,不管是that，whic h，还是whom。
但是which能引导非限制性定语从句，that则不行。
其次，记得以下只能用that的几种情况：1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。
如：We should do all that is useful to the people. 我们应该做一切有益于人民的事情。
Please tell me anything that you know about the matter. 有关此事，凡是你所知道的请告诉我。
2. 当先行词被any, few, little, no, not, every, each, all, much, some等词修饰时。
如：You can take any seat that is free. 任何空着的座位你都可以坐。
There is little work that is fit for you. 几乎没有适合你的工作。
3. 当先行词为序数词或被序数词所修饰时。
如：When people talk about the cities of China, the first that comes to my mind is Beijing. 人们谈论起中国的城市的时候，我首先想到的是北京。
This is the fourth film that has been shown in our school this term. 这是我们校本学期放映的第四部电影。
4. 当先行词为形容词最高级或被形容词最高级修饰时。
如：The best that I could do was to apologize. 我唯一能做的就是赔礼道歉了。
This is the most interesting story book that I have ever read. 这是我读过的一本最有趣的故事书。
5. 当先行词被the very, the only, the last, the just,the same等修饰时。
如：This is the very book that I’m looking for. 这正是我在找的书。
The only thing that we could do was to wait. 我们唯一能做的事就是等待。
注意：先行词被the same修饰时，关系代词也可用as。
如：I need the same book that / as you have. 我需要有你一样的书。
6. 当先行词既包含人又包含物时。
如：They are talking of the heroines and their deeds that interest them. 他们正在谈论他们感兴趣的女英雄及她们的事迹。
7. 当先行词是疑问代词who，which，或主句以这些词开头时。
如：Who that has ever worked together with him doesn’t admire him? 曾经和他一起工作过的谁不钦佩他？Which is the star that is nearer to the earth？哪个是离地球比较近的星星？8. 当先行词为主句表语或关系代词为从句表语时。
如：That’s a good book that will help you a lot. 那是本对你很有帮助的书。
Our school is no longer the place that it used to be. 我们的学校现在已不是过去的那个样子了。
9. 先行词为time时，当time表示次数，引导词用that, 可省略。
当表示时间，可用that 或when引导，都可省略。
如：I do remember the first time(that) I had ever heard the sweetest voice in the w orld.我很清楚地记得当我第一次听到世界上最美的声音的时候。
I didn't remember the exact time （when/that）I arrived in Shanghai last month. 我不记得上个月到达上海的确切时间了。
最后，请注意以下几种只能使用which的情况:1. 在“介词＋关系代词”结构中，关系代词必须用which。
如：The house in which we live is very large. 我们住的房子非常大。
This is the reference book of which the teacher is speaking. 这就是老师正在谈及的那本参考书。
注意：如果介词不放在修饰事物的限定性定语从句的句首，which就可换为that，例如：This is the question which/that we’ve had so much discussion about.=This is the question about which we’ve had so much discussion. 这就是我们已经多次讨论过的问题。
2. 先行词为“those＋表事物的复数名词”时，关系代词通常只用which而不用that。
如：You should grasp well those skills which may be used in the future work.3、当主句中的主语被that修饰时。
e.g. That dog which I found in the street belongs to Mary.最后，记得这个特殊情况吧：当先行词是表示原因或方式的名词时，可以用that引导定语从句，相当于介词+which，that可以省略。
如：She likes the child for the very reason that (=for which) she loves his father. 她喜欢那个孩子因为她爱着孩子的父亲。
He didn’t like the way that (=in which) she speaks to his mother. 他不喜欢她对他的母亲那样说话。
Imagine the speed that (=at which) he drives the car. 很难想象，他开车开得那么快。
The reason (that /for which /why) he came here was to ask for our help.他来这里的原因是寻求我们的帮助。
四、As引导的定语从句1. as用作关系代词和关系副词引导限制性定语从句，并在从句中作主语、宾语、状语或表语，构成the same…as, such…as, so…as, as…as…等结构，也就是说，先行词之前一旦出现same, such, so, as这些词时，而先行词的后面又跟着一个从句，这时就要考虑是不是要用as作为关系词来连接这个词和这个句子。
