第二章 从句

一、含义

从句是由连词引出的句子在整句话中充当某种成分

二、分类(根据所代替成分的词性)

从句在句中充当什么成分就是什么从句

1.名词性从句

主从、宾从、表从、同位从

2.形容词性从句

定从(由连词引出的句子充当定语,修饰n)

3.副词性从句

状从(由连词引出的句子充当状语,修饰v)

第一节 名词性从句

由连词引出的句子充当宾语成分, V后/介后

表从

由连词引出的句子充当表语成分, be后

同位从

由连词引出的句子充当同位语成分,n后

三、连词

做题方法:

1.划从句,判断类型

划从句:如果一句话有两个动词,且无连词,那它便是主从复合句。从连词开 始,到第二个动词之前为从句部分,若没有第二个动词,则划至句末。

2.判断从句是否缺成分

3.判断整句是否缺含义

1. that

(无成分,无含义)

I can't believe that the accident happened in such a way

宾语从句

That English teacher is gorgeous is a truth

主语从句

We heard the news that our team had won

同位语从句

His advantage is that he always focuses on one question

表语从句

2. whether/if, when, where, why, how, which, whose

(无成分，有含义）

I wonder whether/if/where/when he'll be free tomorrow

It depends on whether /when/where we will have enough money

Whether/when/where/why/how he will become famous again is unknown

When/Why/Where/How Jack left hometown wasn't clear

Which brand he will buy depends on himself.

We all know whose responsibility it is

补:

(1) if表示是否,只用于宾从(实意动词引导的) whether可引导所有名从

(2) whether... or not 是否

3.what,who,whom

(有成分，有含义）



What you said sounds reasonable

Nobody knows who broke the glass

Whom/What the staff hated was obvious

四、注意

1.从句需用陈述语序(主+谓)

How are you? I wonder how you are.

2.主语从句和宾语从句的变形。

1)主语从句的变形,用it作形式主语

当主语从句较长，常将主语从句后置，而用it作为形式主语置于句首。

When and where we will hold our sports meeting is hard to decide

It is hard to decide when and where we will hold our sports meeting.

2)宾语从句的变形，用it作形式宾语

I think that we spent so much money on these books worthwhile

I think it worthwhile that we spent so much money on these books

注: consider/ find/ think/ feel/ make等动词常带宾语补足语，这时要用形式宾语it，宾语从句放到宾补之后。

3.宾语从句中that可以省略

I believe (that)prevention is better than cure

4.固定句型:

A is to B what C is to D

A对于B,犹如C对于D一样

A pen is to a writer what a gun is to a soldier

第二节 定语从句

Xi'an is a beautiful city that a lot of people visit.

先行词

一、含义

定语从句是由连词引出的句子充当定语,修饰名词。

二、连词

l.that, which,who,whom

(有成分,有含义)



做题方法:

1.划从句,判断类型

划从句:如果一句话有两个动词,且无连词,那它便是主从复合句。从连词开 始,到第二个动词之前为从句部分,若没有第二个动词,则划至句末

2.判断从句是否缺成分

3.看先行词 指人 还是指物

考点链接

（一）n+从句

同位语从句:前面的名词通常为抽象名词,且抽象名词=从句

He told me the news that he passed the exam

the news= that he passed the exam

定语从句:名词≠从句,从句修饰限定名词

He told me the news that made him excited

the news≠that made him excited

判断从句类型,填适当连词

1. The fact that they didn't finish the work was terrible

同位语从句

2. The fact (that/which）they ignored was terrible

定语从句

（二）省略连词

1.宾语从句中that可以省略

I believe(that) he gets the first prize.

2.定语从句中that作宾语可以省略

This is the game (that) I like？

（三）that与which区别(当先行词指物作主语或者宾语时)

1.只能用that

(1)先行词是不定代词 all, some-, any-, no-, every-

All that your ordered is here

(2)先行词被绝对意义的词修饰时,比如序数词,最高级，the very, the only

The first thing that attracted me was your smile

(3)先行词既有人也有物

There are many kids and toys that reminded me of my childhood

2.只能用 which

(1)非限定性定从

(2)连词位于介词之后,作宾语

Xi'an is a city in which we live

The board on which they stood was made of wood

总结:定从中that与 which的区别

只用that

先行词为不定代词

先行词含绝对含义

先行词既有人又有物

只用 which

非限定性定从

连词位于介词之后，作宾语

2.when，where，why,whose

(无成分,有含义）

I still remember the first day when I came to school

This is the city where i have stayed for two years.

I can't forget the reason why I chose this school.

The man whose name is Li Xian is my boyfriend.

考点链接:介词+ which

1.介词+ which替代when, where,why

I still remember the first day when/on which I came to school

This is the city where/in which I have stayed for two years

I can't forget the reason why/for which I chose this school.

→当先行词表示时间 地点 原因时,介词选用根据从句和先行词的含义关系。

Xi'an is the place where/in which I grew up.

He likes the holiday when/during which he can travel around the city

2介词选用根据从句中的动介搭配

当先行词不表示时间 地点 原因时,介词选用根据从句中的动介搭配。

This is the book about which I often talk.

This is the book for which I paid 100 RMB.

三、类型

1.限定性定从

主从句间无逗号

只能修饰名词(先行词)

连词常规使用

例句

Li Xian is a man that/whom many girls adore

2.非限定性定从

主从句间有逗号

既能修饰名词,也能修饰句子

连词无that,其它连词用法相同

例句

He is a boy, who smokes

The book, which I bought, is interesting

He smokes, which surprises us

四、固定句型

...先行词，数词/名词/代词 of which/whom...

In this movie there are many characters, 2 of whom are animals. The main character is a cat, the name of which is Garfield. A lot of people, most of whom are children, like the movie
