1、 名词性从句

(1) 主语从句

What he wants is a piece of paper.

It is believed that he can solve the problem.



I don't know how to solve the problem.

Do you know where he lives?


The problem is who can help me.

This is why I came here.


I have no idea where he went.

I heard the news that he would come.

同位语从句用that引导,常跟在fact, idea, news, promise, thought, message, hope, belief, doubt等词后,that在从句中不作任何成分。


在复合句中,修饰某一名词或代词,或修饰整个主句的从句叫做定语从句,引导定语从句的关系代词有who, whom, whose, which, that, as,和关系副词when, where, why。


a. 先行词有all, everything等不定代词时,如,

Everything (that) he did is wrong.

b. 先行词被all, every, no, some, any, little, much等修饰时,如,

I'll read all the books (that) you lend me.

c. 先行词被序数词或形容词最高级修饰时,

This is the first letter (that) the boy has written.

d. 先行词被the only, the very, the same, the last修饰时,如

He is the very man (that) I'm looking for.

e. 只用which的情况


This is the book about which we have talked a lot.

The book, which he gave me yesterday, is very interesting.

f. where和when作关系副词

This is the room where I worked.

This is the room which I stayed in.

I remembered the day when we lived there.

g. as和which

as 可以放于句首,而which 不可以

As you know, he is good at English.

three of them 和three of which

I have a lot of books, three of which are in Russian.

I have a lot of books and three of them are in Russian.
