名词性从句

第一节主语从句

引导主语从句的连接词有：that, whether, who, which, what, when, where, how, why等

That she was invited to the ball made her very happy.

Whether he will come to the ball has nothing to

do with me.

Whoever wants to see the film may get a ticket free.

Which team will win the match is still unknown. What interests you doesn’t interest him. Where they had stayed was still unknown.

When they will have a meeting hasn’t been decided.

注意：1从句作主语谓语动词用第三人称单数形式。Who will go is not important.

2

2为了调节句子平衡，常用it作形式主语。It is a pity that he didn’t come yesterday.

It’s necessary that every League member (should) take the lead and work well.

It’s suggested that a modern hotel (should) be

put up at the foot of the hill.

3陈述句部分的主语是从句时，其反意疑问句部分的

主语用it.

How he became a scientist is known to us all,

isn’t it?

第二节宾语从句

作动词、介词或形容词宾语的从句。以连词 that who whom whose what 等引导，在句子中充当宾

语

I think (that) you will like the pictures.

I feel it important that they finish their own

task in time.

They are worrying about whether they can get

there in time.

You can write about whatever topic you can think of.

一宾语从句三原则：语序；时态；引导词。 1.语序：宾语从句用陈述句语序。

I wonder what he is writing to me about但是：what’s the matter/wrong (with)……语序不变.The owner came up to see what was the matter with

me/what was wrong with me

2.时态：宾语从句谓语动词的时态与主句谓语动词的

时态保持一致。

(1).如果主句的谓语动词是一般现在时或一般将来

时，宾语从句用它本身的时态。I hear he will come back in an hour.(2).如果主句的谓语动词是一般过

去时，宾语从句则用相应的过去时态。

She said that he had never been to the Great

Wall.(3).如果宾语从句的内容是客观真理时，宾语

从句仍然用一般现在时。The teacher told us that

the earth goes around the sun. / light travels

faster than sound.3.引导词：（1）由that引导（2）由if/whether引导（3）由特殊疑问词引导

二 it在宾语从句中的应用：

1. vt.+it+adj./n.+that-clause 或wh-clause。She has made i t clear that she will have nothing to do with him.

2.i)在主谓宾结构中，有一些习惯上不以

that-clause或 wh-clause从句直接作宾语的动词，如果要接宾语从句，往往需要在从句前加上形式宾语it. The newspapers have it that some Japanese

firms have gone bankrupt.报纸说有几家日本公司

已破产

这类动词还有：have（表明，坚持说）,take（认

为）,hide（隐瞒）,love ,like，

dislike, hate, enjoy

ii) 在主谓宾结构中, 如果谓语动词是短语动词，即动词+介词，一般不能that接从句。如果接从句，必须加上形式宾语it. I will answer for it that Lao Ma will accomplish the task.

5

我担保老马能完成这项任务Look to it that you

make no more similar mistakes.

注意今后你不再犯类似的错误了I am c ounting on it that you will come.我期待着你的到来

这类动词还有：depend on, see to etc.

iii)某些固定搭配之后如果接that宾语从句,也必须使用作形式宾语it.

We owe it to you that there wasn’t a serious accident.这次事故没造成严重的后果全靠你

I didn’t send you an invitation, as I took it

for granted that you would be coming.

因为我认为你当然会来,所以没有给你发请柬

三1 否定的转移当主句的谓语动词是think,

believe, suppose, expect, imagine等表示

看法的动词时,宾语从句中谓语动词的否定式,

习惯上前移到主句的谓语动词上.

I don’t think that he will be back until nine.
