高考英语语法专题复习：定语从句

高考英语复习6.定语从句（语法）语法讲座：定语从句一、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。

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。

二、关系代词1．who先行词是“人”，在从句中代替主语。

注意：代替从句中的主语，who不能省略。

who的单复数由先行词决定。

但是要注意“one of +先行词”与“the only one of +先行词”的情况。

2．whom先行词是“人”，在从句中代替宾语。

whom在从句中经常可以省略，但如果在介词后面，则不能省。

3．which先行词是“物”，在从句中可以代替主语或宾语。

which代替主语时，不能省略，它的单复数由先行词决定。

which 代替宾语时则经常省略，但如果在介词后面，那么也不能省略。

which的先行词有时还可以是前面的整个句子，这时它总是看成单数，也不能省略。

4．that先行词可以是“人”，也可以是“物”，在从句中可以代替主语或者宾语。

that代替主语时，不能省略，代替宾语时则经常省略。

that不能用在介词之后。

在以下三种情况时，我们一般不用关系代词who, whom, 和which，而只用that：1）先行词是不定代词如anything, something, all等词，或由all, every, little, any, much, the very 等词所修饰；2）先行词前有最高级形容词或序数词所修饰；3）先行词是由and连接的两个词，分别指“人”和“物”。

5．whose先行词可以是“人”，也可以是“物”，在从句中代替定语。

whose不能省略。

如果先行词是“物”，我们也可以用sth. of which代替whose。

牛津译林版英语高考英语语法专题复习：定语从句归纳拓展讲解语法专题一定语从句定语从句在句中作定语，修饰名词或代词。

被修饰的名词或者代词被称为先行词，定语从句一般放在先行词的后面。

引导定语从句的词被称为关系词，关系词有关系代词和关系副词，它们在先行词和定语从句之间起引导作用，在意义上代替先行词，在定语从句中充当一个成分。

其基本解题方法是：第一，找出先行词；第二，看先行词在定语从句中充当的成分，作主语、宾语、表语或定语时要用关系代词，如果作状语，则要选用关系副词；第三，看先行词是否为特殊词，然后根据需要选用合适的关系词。

考点一关系代词与关系副词的区别关系代词有who，whom，which，tha t和whose，另外，as 也可充当关系代词。

关系代词在定语从句中充当主语、宾语、表语和定语。

关系副词有when，where 和why，在定语从句中充当状语。

1．who 指人，在定语从句中作主语或宾语。

The boys who are playing football are from Class One.2．whom 指人，在定语从句中作宾语，常可省略。

Mr Liu is the person（wh o m）you talked about just now.3．which 指物，在定语从句中作主语或宾语，作宾语时常可省略。

The book which he gave me is very interesting.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。

She is the pop star（that）I want to see very much.5．whose 可指人或物，修饰名词或代词，在定语从句中充当定语。

“whose＋名词”可改为“the＋名词＋of which/whom”或“ofwhich/whom the＋名词”。

The house whose windows are very large is my uncle's.＝The houseof which the windows are very large is my uncle's.6．as 可指人也可指物，在定语从句中作主语、宾语或表语。

There are many places we can visit（them）in China.4、关系词：引导定语从句的都称关系词关系代词：who, whom, which, that, whose, as。

关系副词：when, where, why。

（2）看关系词在从句中所充当的成分。

高考英语语法之从句讲义：定语从句精讲充当定语的句子叫定语从句。

定语从句修饰的名词叫先行词(the antecedent).定语从句由关系代词: who, whom, which, 关系形容词whose 和关系副词when, where, why引导，关系词除了起连接从句和名词的作用外，还作从句的句子成分。

1.限制性定语从句Who的先行词是人，作定语从句的主语：This is the man who will give us a talk tomorrow.Whom的先行词是人，作定语从句的宾语：This is the man whom I talked about the other day.Which 的先行词是物，作从句的主语和宾语Here is a book which may be helpful in you English study.This is the book which I like best.上述例句都可改用that.Whose是个关系形容词，在从句中作定语。

A teacher is a person whose duty is to teach.When, where, why 分别作从句的时间状语、地点状语和原因状语。

He will never forget the day when the accident took place.This was the room where we studied.Do you know the reason why he was late?2.非限定性定语从句：非限定性定语从句所修饰的先行词可以是名词（许多是专有名词），也可以是整个主句，它对先行词不加限定，只起附加说明作用，如果没有，也不影响句意和语法结构。

非限定性定语从句和先行词书写时有逗号断开。

Yesterday I happened to see John, who was eager to have a talk with you.She was late again, which was annoying.区分限定性定语从句和非限定性定语从句很重要。

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。

关系词常有3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。

3. 先行词：被定语从句修饰的名词、代词称为先行词。

一、关系词的用法(一)关系代词who, whom, whose, that, which（在句中作主语、宾语或定语）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。

语法复习四：定语从句（一）定语从句一般由关系代词和关系副词引导1、关系代词：who, whom, whose, which, that, as2、关系副词：when, where, why关系代词和关系副词必须位于从句之首，主句先行词之后，起着连接先行词和从句的作用，同时在从句中又充当句子成分。

e.g. She is the girl who sings best of all.（关系代词who在从句中作主语）The comrade with whom I came knows French.（whom在从句中作介词with的宾语）3、关系代词和关系副词的用法：1）当先行词为人时用who 作主语，whom作宾语；2）当先行词为物或整个句子时用which ，可作主语或宾语；3）先行词为人、物时用that ，可作主语或宾语；4）whose用作定语，可指人或物；5）关系副词when（指时间，在定语从句中作时间状语，where（指地点，在定语从句中作地点状语），why（指原因，在定语从句中作原因状语）。

（二）限制性定语从句与非限制性定语从句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。

e.g. Tom’s father, who is over sixty, still works hard day and night.（who引导非限制性定语从句，整个句子可分成两句来翻译）（三）使用定语从句时特别注意的几个问题1、that与which的区别。

1）用that而不用which的情况：①先行词为不定代词all, anything, nothing, …；②先行词有最高级修饰，有序数词修饰；③先行词有only, very, any等词修饰；④先行词既有人又有物时。
