(完整版)定语从句语法详解
定语从句语法专题（Attributive Clauses）教案一. 定语从句的概述:1.定语从句：在复合句中，修饰某一名词或代词的从句叫定语从句。
在句中做定语，被修饰的名词或代词，叫做先行词。
从句通常放在先行词之后，由关系词（关系代词或关系副词）引导。
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。
eg She is the girl（who got the first prize.）girl先行词who充当从句主语, 从句做定语修饰girlThis is the boy who broke the window.这就是打破窗子的孩子。
the boy是先行词, who broke the window是限制性定语从句, 明确指出theboy是打破窗子的那个孩子,who 在从句中充当主语That is the house where he lived ten years ago.He is the man who/that lives next door.He is the man who I want to see.先行词关系词定语从句复合句: 是由一个主句和一个或一个以上的从句构成的句子, 复合句中的主句和从句都具有完整的的主语和谓语, 主句是复合句的主体, 可以独立存在, 从句需要有一个连词引导, 是修饰说明主句的, 不能独立存在, 根据在句中的不同作用, 从句可以分为三类: 定语从句, 名词性从句, 状语从句。
二. 引导定语从句的关系词有两大类:1.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: that, who, whom, whose, which, as（主, 宾, 定）关系副词: when, where, why.（状语）2.关系词的作用:（1）引导定语从句, 在先行词和定语从句之间起连接作用；（2）代替先行词在句中充当成分。

(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。

高考英语一轮复习 语法点专题讲解 定语从句
定语从句Ⅰ. 定语从句的特点定语从句修饰前面的名词或代词，它由“关系代词或副词＋从句”构成，它所修饰的名词或代词称作先行词。
定语从句通常置于先行词之后。
例如：My brother works in the factory which is not far from your house.注意：关系代词或副词在定语从句中，一定充当一个成分。
Ⅱ. 用于限定性定语从句的关系代词who, whom, which, that, whose等关系代词在定语从句中所指对象是人或物，在从句中作主语、宾语、介词宾语或定语。
它们的形式变化如下：Ⅲ. who, whom, that代表人A.who, that作主格，不能省略。
例如：The man who/that spoke at the meeting this morning is a famous lawyer.作主格时，who较that更常用。
B.who, whom, that,作动词的宾语。
口语中常用who或that代替whom。
经常可以省略。
例如：The girl who(m)/that you saw just now is Jane.The girl you saw just now is Jane.C.当先行词是all, nobody, no one, somebody, someone, anybody等词或者名词有形容词最高级或序数词修饰时，指人时who和that都可以用。

2020高考英语一轮复习同步攻关 语法部分 第8讲 定语从
第8讲定语从句1. 定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。
2. 先行词：被定语从句修饰的那个名词或代词称为先行词。
3. 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：who, whom, whose, which, that, as等；关系副词：where, when, why等。
关系词常有三个作用：引导定语从句；代替先行词；在定语从句中充当一个成分。
例如：Harry Potter is the most interesting novel that I have read. (that I have read 是定语从句；novel是先行词；that 是关系代词，代替先行词novel，在从句中作have read 的宾语。
)关系词指代人或物以及在定语从句中充当的成分4. 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和主句隔开，是先行词不可缺少的部分，去掉它主句意思往往不明确，翻译成先行词的定语，“……的……”。
非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，通常翻译成主句的并列句。
关系代词that和关系副词why不能引导非限制性定语从句。
His brother who is now a lawyer always encourages him to go to college.他那个现在是律师的哥哥总是鼓励他上大学。
(他还有其他的哥哥)His brother, who is now a lawyer, always encourages him to go to college.他的哥哥，现在是律师，总是鼓励他上大学。
(他只有一个哥哥)一、关系代词的使用【例句观察】①She is the woman (whom / that / who)I wanted to see yesterday.她是我昨天想看的那个女的。

3 关系代词as的用法
用于限制性定语从句中：当先行词被so，as，such，the same所修饰时，关系代词用as指人或物，而不用which。
用于非限制性定语从句中： 非限制性定语从句，特别是先行词是整个主句时，由which和as引导的非限制性定语从句，是高考命题的热点。
[注] as引导的非限制性定语从句与which引导的非限制性定语从句的区别：
②This is the same place ________ I visited three years ago.
This is the same place ________ I worked three years ago.
③He failed in the exam，________ made his father very angry.
＝The man pulled out a gold watch，of ________ the hands were made of small diamonds.
10找准先行词
一般说来，定语从句是跟在它所修饰的先行词之后，但有时也会出现先行词和定语从句被一个词或一个短语所分隔，或者谓语太短等情况，这时我们要根据定语从句的句意判断哪一个词是先行词。
③当先行词被形容词最高级或序数词所修饰时。
④当先行词被the only和the very所修饰时。
⑤当先行词在定语从句中作表语时。
⑥当要避免与疑问词which重复时。
只用which的场合：
①“介词＋which”，指物。
②非限制性定语从句中。
③防止重复。
④指人的性质身份时，而不是指人时。
用适当的关系代词或关系副词填空：
定语从句和先行词之间常常会有I think，you know，I believe，I thought等插入语。做此类题目时，我们要先去除插入语，再选择正确的关系词。
完成下列句子：
①This is the school ________ you know I once studied.
②I picked up a man ________ I thought was honest.
＝I picked up a man ________ I thought to be honest.
③He made a discovery，________(我认为) is very important.
8只能用that或which的情况
只用that的场合：
①当先行词既指人又指物时。
②当先行词是不定代词anything，nothing，everything，all，some，little，few，much，none或被不定代词修饰时。
He failed in the exam，________ I had expected.
④A lot of language learning, ________ has been discovered, is happening in the first year of life, so parents should talk much to their children during that period.
用适当的关系词填空：
①This is one point ________ we must insist on.
I have reached a point in my life ________ I am supposed to make decisions of my own.
②Occasions are quite rare ________ I have the time to spend a day with my kids.
定语从句
名词或代词后起到修饰作用的句子
从句中少成分： 关系代词
先行词为人who that或whom
先行词为物which或that
先行词为句子which或as
先行词与从句中主语为所属关系whose
从句中不少成分： 关系for which
先行词表时间（常见表时间的词有：period，occasion，stage，interval，stay等）用when=介词which
①He is the person ________ we should learn.
②The bag ________ he put his books is lost.
③The man ________ she is talking is a doctor.
④The train ________ he was travelling was late.
④I don't know the way ________ he used last time.
I don't know the way ________ he solved the problem last time.
2. 介词＋关系代词
介词后只能用which指物，whom指人，不可用that。介词的选用可根据从句中相关词组确定，也可结合句意根据先行词确定。该介词也可放在从句之尾。用适当的“介词＋关系代词”填空：
6定语从句中的数要保持一致
完成下列句子：
①Those who ________(break) the law should be punished.
＝Anyone who ________(break)the law should be punished.
＝Whoever ________(break) the law should be punished.
用适当的关系词填空：
①Do you know the man in ________ car she came here?
②The man pulled out a gold watch，________ hands were made of small diamonds.
＝The man pulled out a gold watch，the hands of ________ were made of small diamonds.
①He told us all ________ had happened.

③This is the first place ________ we visited yesterday.

④This is the only plant ________ grows in the area.

4 并列句和非限制性定语从句的判断
并列句是由两个简单句组成的，句子中间必须要有并列连词；而定语从句是由主句和从句构成的。
完成下列句子：
①He has two brothers，and both of ________ are workers.
He has two brothers，both of ________ are workers.
③The days are gone ________ we used the foreign oil.
11“the one＋that/which/where”和that，which，where的区别
完成下列句子：
①Is this the museum ________ you visited last year?
Is this museum ________ you visited last year?
as引导的非限制性定语从句可以放在主句前、插在主句中间或放在主句末尾，而which引导的非限制性定语从句只能放在主句后面；as引导的从句有“正如”之意，而which则没此意。
用适当的关系词填空： ①This is such a heavy bag ________ I can't carry.
This is such a heavy bag ________ I can't carry it .
He may not come and in ________ case we will not wait for him.
5先行词模糊化
表地点的先行词模糊化在句中作状语时用关系副词where，相当于in which；在句中作主语和宾语仍用关系代词。常见的词有：point，situation，position，profession，job，case，system，scene，activity，society，culture，strategy，model，accident，economy，crime等；常见的表时间的词有：period，occasion，stage，interval，stay等。
①I still remember the day ________ we studied together.
