定语从句
1. 限制和非限制性定语从句:限制性定语从句是名词词组不可缺少的一个组成部分, 去掉了会造成病句或意义不明确; 非限制性定语从句属于补充说明性质, 去掉了不会影响主要意义, 通常用逗号与它的先行词分开.
The boys who wanted to play football were disappointed when it rained.
The boys, who wanted to play football, were disappointed when it rained.
如果定语从句的先行词是专有名词, 或是带有形容词性物主代词(my, his, etc)或形容词性指示代词(this, that, etc)作限定词, 其后的定语从句通常都是非限制性的: Mary Smith, who is in the corner, wants to meet you.
Her mother, who had long suffered form arthritis, died last night.
All these books, which have been donated by visiting professors, are to be used by the postgraduates.
在非限制性定语从句中只能用who/whom指人, 用which指物,通常不用that替代.
My father, who had been on a visit to America, returned yesterday.
All the books, which had pictures in them, were sent to the little girl.
2. 定语从句的引导词
1) that, who, whom: 非限制性定语从句, 如果修饰人, 一般用who,有时用that (作主语时用who较多). 如果关系代词在从句中作宾语, 就应当用宾格 whom 或that,但在大多数情况下都可以省略掉, 在口语中可用who代替whom.
Here is the man (whom) you’ve been looking for.
He is a man (that) you can safely depend on.
The people (who/that) you were talking to were Swedes.
There are some people here who I want you to meet.
但在介词后只能用whom:
This is the man to whom I referred.
但在口语中一般都把介词放到句子后面去, 这时可用that, 但省略时更多一些.
Have you met the person about whom he was speaking?
Have you met the person (that) he was speaking about
The girl to whom I spoke is my cousin.
The girl (who/that) I spoke to is my cousin.
2) 限制性定语从句如果修饰“物”, 用关系代词that的时候较多, 也有时用which..当这个代词在从句中是用作宾语时, 在绝大多数情况下都是省略的, 特别是口语中(尤其是当被修饰的词是all, everything等词时):
Have you everything you need?
(Is there) anything I can do for you?
All you have to do is to press the button.
在介词后只能用which, 在口语中一般都把介词放到从句后部去, 这时可以用that, 但省略的时候更多一些:
The tool with which he is working is called a wrench.
The tool (that) he is working with is called a wrench.
This is the question about which we’ve had so much discussion.
This is the question (that) we’ve had so much discussion about.
定语从句一般是修饰名词或代词的, 但间或也可以修饰整个句子a), 或是句子的`一部分b), 引导词用which:
a) They have invited me to visit their country, which is very kind of them.
The activity was postponed, which was exactly what we wanted
b) When deeply absorbed in work, which he often was, he would forget all about eating and sleeping.
She was very patient towards the children, which her husband seldom was.
3) whose: 在表示“．．．的”这个概念时, 可用所有格 whose; whose 用于指物, 有时可与of which交替使用, 通常的词序是 名词词组 + of which:
Is there anyone in your class whose family is in the northeast?
We had a meeting whose purpose was completely unclear. (…the purpose of which was…) He’s written a book the name of which I’ve completely forgotten. (…whose name I’ve…)
of which前的名词词组也可以由some, any, none, all, both, several, enough, many, most, few以及基数词担任; 这些词也能用在of whom之前.
The buses, most of which were already full, were surrounded by an angry crowd.
It’s a family of eight children, all of whom are studying music.
4) 关系副词 when, where, why: 它们的含义相当于 at which, in which, for which, 因此它们之间有交替使用的可能.
The day when he was born…
on which he was born…
which he was born on…
The office where he works…
at which he works…
which he works at…
有时可用that替代关系副词, 在口语中that可省略.
Every time (that) the telephone rings, he gets nervous.
This was the first time I had serious trouble with my boss.
Do you know anywhere (that) I can get a drink?
This is the place (where) we met yesterday.
That is the reason (why) he did it.
在the way 后也可用that 替代in which, 在口语中that也可省略.
This is the way (that/in which) he did it.
That’s the way I look at it.
3. 如果定语从句中谓语为there is, 作主语的关系代词也常可省掉:
I must make full use of the time there is left to me and do as much as I can for the people.
This is the fastest train (that) there is to Nanjing.
4. 定语从句的简化:定语从句与不定式结构, -ing分词结构, -ed分词结构以及无动词分句等有着转换关系.
He was the only one to realize the danger (= who realized the danger).
The woman driving the car (= who was driving the car) indicated that she was going to turn left. The man injured by the bullet (= who was injured by the bullet) was taken to hospital.
All the women present (= who were present) looked up in alarm.
第2篇：定语从句语法总结
定语从句语法总结
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。以下是小编为大家整理分享的定语从句语法总结，欢迎阅读参考。
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：that/who/whom/which/as
（2）关系副词：when/where/why
5.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（whom/which）引导
The man to whom you’re talking is my friend.
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 (who/whom/that) 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 (which/that) 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）。
① 直接由引导词引导定语从句。
② 由介词+关系代词（whom/which）引导。
I live in a house far away from the city, in front of which is a big tree.
There is an apple tree standing at the gate, on which are many apples.
This is the man to whom I gave the book.
③ 由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”(先行词指
人用whom,指物用which)引导。One, some, any, none, all, both, several, many, most, neither, either等词、数词、分数或百分比与of whom或of which连用。
He has five children, two of whom are abroad.
(比较：He has five children, and two of them are abroad.)
We have three books, none of which is/are interesting.
(比较：We have three books, but none of them is/are interesting.)
除why和that不能引导非限定性定语从句外，其余引导词都可以，用法同限定性定语从句一样。但要注意以下区别。
1.在形式上非限定性定语从句与主句有逗号隔开。
2.非限定性定语从句的作用：它只是补充说明先行词的情况，翻译时可译成两个句子。
The engineer, whose leg was badly hurt, was quickly sent to hospital.
（那位工程师被很快送往医院，其腿部受了重伤）
The engineer whose leg was badly hurt was quickly sent to hospital.
（那位腿部受了重伤的工程师被很快送往医院）
3.在非限定性定语从句中，任何引导词都不能省略（包括引导词在此定语从句中充当宾语在内）。指人做主语时只能用who, 做宾语时用whom; [要学习网-中学生最喜欢的学习论坛；网址www.yaoxuexi.cn手机版地址wap.yaoxuexi.cn]
指物做主语，宾语都用which; 关系副词用when或where，也不能省略。
The man, ______ is sitting on the chair, is my father.
The woman, _______ I met yesterday, is my English teacher.
The city, _______ is far away, is very beautiful.
He went to America, ______ his parents live.
He joined the Army yesterday, ______ I left, too.
4.whose引导非限定性定语从句：
The house, whose window faces south, is mine.
=The house, the window of which faces south, is mine.
＝The house, of which the window faces south, is mine.
二.定语从句中关系代词和关系副词的基本用法
1.who/that指人是主格在定语从句中代替先行词，又作定语从句的'主语，不能省略。
Do you know the gentleman who/that is sitting there?
2.whom/who/that指人是宾格，在定语从句中代替先行词，又作定语从句的宾语（动宾或介宾）。
① 当作动宾（动词后接宾语）时，关系代词可省略。
Do you know the gentleman (whom/who/that) we met just now?
② 当作介宾（介词后接宾语）时：
介词不提前时，关系代词可省略；
介词提前时，关系代词不可省，即介词＋whom(指人时介词后的关系代词只能用whom)。
The man (whom/who/that) I spoke with is my teacher.
The man with whom I spoke is my teacher.
※注：固定的动词短语（动词+介词）如look for, take care of等不能把动词与介词拆开，既介词不能提至引导词前。
She is the right girl (who/whom/that) we are looking for.
3.whose: 指人或物，是所有格“…的”形式。Whose+n.一起在定语从句中充当主语、宾语（动宾或介宾）即先行词的什么东西怎样了，whose不能省略。。Whose+n. = the +n. + of which/whom= of which/ whom+ the =n.
I didn’t find the desk whose leg was broken. （主语）
He is the student whose pencil I broke yesterday. （动宾）
The boss in whose company I work is very kind. （介宾）
4.which/that 指物，指代先行词且在定语从句中作主语或宾语（动宾或介宾）。
① 当作动宾时，关系代词可省略。
② 当作介宾时：
介词不提前时，关系代词可省略；
介词提前时，关系代词不可省，即介词＋which(指物时介词后的关系代词只能用which)。
The house which/that was destroyed in the earthquake is weak.
The pen (which/that) you found yesterday is mine.
The games (that/which) the young men competed in were difficult.
The games in which the young men competed were difficult.
※注:介词+关系代词即介词+whom/which(先行词指人用whom，指物用which)。
※5.as指人或物，在定语从句中可作主语，宾语，表语或状语，不能省略。主要用于 “the same …as…；such …as…；so …as…；as … as…；as follows”固定结构中，形式固定此时的引导限定性定语从句。要用as代替who(m), which, 或that引导定语从句：
Such people as knew Hill thought he was honest.
Such people as Hill knew thought he was honest.
My hometown is no longer the same as it was.
Here is so big a stone as no one can lift.
The child knows as much as grow-ups (know).

定语从句概述
I关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、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。
1）who,whom,that
这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如：
Ishethemanwho/thatwantstoseeyou?他就是你想见的人吗？（who/that在从句中作主语）
Heisthemanwhom/thatIsawyesterday.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ofwhich互换）。例如：
Theyrushedovertohelp
