【#英语资源# 导语】主语从句,即在复杂句中充当主语成分的句子,例如"That he finished writing the composition in such a short time surprised us all",他在很短的时间内写完作文让我们都很惊讶,此复合句主要描述的是某事让我们惊讶,某事就是该复合句的主语,因此“That he finished writing the composition in such a short time”便是该复合句的主语从句。©文档大全网整理了相关内容,快来看看吧!希望能帮助到你~更多相关讯息请关注©文档大全网!





1. 主语从句如果表达的是一个事实,一般由that引导。that在从句中无词义,不充当句子成分,仅起引导作用。如:

That she was chosen made us very happy. 她被选上了,我们很高兴。

That the earth goes round the sun is known to us all.


2. 由whether引导的主语从句,表示“是否”之意,注意不能用if。

Whether she will come or not is still a question.

他能否来还是个问题。

It is doubtful whether he will be able to come.

她能否来令人怀疑。


3. 由疑问词引导的主语从句,从句中要用陈述语序。如:

What should be done has been done.

应该做的事情都做了。

What we need is more time.

我们所需要的是更多的时间。

When we shall have our sports meet is still a question.

= It is still a question when we shall have our sports meet.

什么时候开运动会还是个问题。

What he did is not yet known.

= It is not yet known what he did.

他干了什么还不清楚。


4. whatever,whoever,whichever等引导的主语从句。(注意不能转化成it作形式主语的句型)。如:

Whatever was said here must be kept secret. 这儿无论说的什么事都必须保密。

Whoever breaks the law will be punished. 无论谁犯了法都要受到惩罚。

Whichever you choose is fine with me.无论你选哪个我都无所谓。


5. 常见句型

1)由“It is + adj. + that…”构成的主语从句。

It is certain that we shall be late. 我们肯定要迟到了。

It’s strange that he didn’t come yesterday. 真奇怪他昨天没来。


2)由“It is + n. + that…”构成的主语从句。

It is a pity that you didn’t see the film yesterday.

It is a wonder that he refused such a good offer.


3)由“It is + 过去分词 + that…”构成的主语从句。

It is reported that the sports meet has been put off.

据报道运动会推迟了。

It has not been decided that when and where we will hold the meeting.

什么时候,在哪里开会还没有决定。


4)由“It + 不及物动词 + that…”构成的主语从句。

It turns out that he has never been there.

原来他根本没去过那儿。

It occurred to her that she might as well talk it over with him. 她想起不妨去和和他谈谈这件事。
