The usage of noun clauses:

名词从句包括主语、宾语、表语和同位语等从句。它们可以由下列连词引导：从属连词that, whether, if；连接代词who(ever), whom,

whose, what(ever), which(ever)；连接副词when, where, why, how, how much / many /long /often 等。

1. 主语从句：在复合句中充当主语的从句叫主语从句，上述引导词除if外均可引起主语从句。

That he is an honest boy is known to all.　

What makes her different from others is her strange behaviour.

Whatever was said here must be kept secret.

主语从.句常放在句尾而用it 作形式主语使句子更加平衡，这时口语中常省略that, 如上面第一句改成“It is known to all that he is an honest boy”更好。在下列情况下必须把主语从句放在句尾而用it 作形式主语：

　1) 主句谓语是被动语态时，如：

It is said that he is a good doctor.

　2)．主句是疑问句或感叹句时，如：

Is it true that the film star will come?

How wonderful it is that we'll visit the Great Wall tomorrow. 3)．主句谓语动词是appear, turn out, happen, occur, come, strike, follow, matter 等

　It happened that she had a cold and didn't go with us that day.

　It turned out that I was wrong.

4)．表示说话人的推测或评价，如在it seems, it may be, it is (un) likely, it is (im)possible, it is a pity, it is a wonder 等结构中，如：

It seems that this test is reliable.

It is a pity that he should go without telling anyone　

　5)．强调主句的表语时，如：

It is a mystery to me how it all happened.

It is necessary that you should tell him the truth

2. 宾语从句：在复合句中作宾语的从句叫宾语从句，以上连词都可引起宾语从句。

I thought (that) you had read the book.

We should learn to tell whether an element is poisonous or not. Do you know who invented this?

1)．宾语从句后有宾语补足语时常移至句末，而用it 做形式宾语放在前面，如：

We should make it clear that protecting the environment is everyone’s duty.

2 ) 宾语从句可作某些介词和某些作表语用的形容词的宾语，如： The resistance of a wire also depends upon what material it is made of.

We are sure (that) it will be a success.

宾语从句应注意的几个问题：

①当一个动词带有两个或两个以上that 引导的宾语从句时，第一个that 可以省略，但从第二个开始不可以省略。

He said (that) he would spend his winter holiday in London this year and that it would be the first time he would spend his holiday alone abroad.

②当宾语从句有补语时，要用形式宾语it代替，而将宾语从句移至补语后，同时that不可省略。

We should make it clear that protecting the environment is everyone’s duty.

We find it important that one forms a good habit.

③在tell sb. that…; order sb.that…; remind sb.that…; explain to sb. that…; whisper to sb. that…等结构中that 不可省。

He told me that he was going abroad next month.

He whispered to me that the man in blue is a policeman.

④在be+adj.后的宾语从句中，that 可以省略。

I’m glad (that) I’ll see all my fiends soon.

I’m sure (that) he will stand on our side.

⑤ whether和if 均能引起宾语从句，但是if 只能在动词后，在介词后要用whether。

He asked whether/if we could do him a favour.

We wondered whether/if he would come or not.

---Will you come tomorrow?
