分析下列各句：

1. That the earth is round is true. = It is true that the earth is round.

2. Whether he will come hasn’t been decided. = It hasn’t been decided whether he will come.

3. Who let out the news remained unknown. = It remained unknown who let out the news.

4. Why he didn’t come here is not clear to anyone. = It is not clear to anyone why he didn’t come here.

5. Whenever the Olympic Games will be held in Beijing is not known yet.

一．名詞性從句簡介

1、主語從句

主語從句在從句中作主語，主語從句可以位于句首，但常見的主語從句多放在句末，句首則用形式主語it。

注意：連詞that, whether在從句中不擔任句子成分，只起連接作用，不能省略。并且whether引導主語從句時不能用if代替。

注意：who, which, how, when, where, why在所引導的主語從句中可擔任主語，賓語，狀語，不能省略。可以用形式主語it引導。

注意：who, whom, which, what等可以和ever構成合成詞，引導主語從句和賓語從句。此類主語從句不能用it引導，引導詞在句中擔任句子成分，不能省略。

另外，有的“It …＋主語從句”已成為固定結構。如：

a. It is +名詞＋從句 It is a pity that we can’t go.

b. It is ＋形容詞＋從句 It is clear that Tom has returned.

c. It is ＋過去分詞＋從句 It is said / reported / believed / known …

主語從句不可位于句首的五種情況：

(1）It is said /reported…結構中的主語從句不可提前。例如：

It is said that President Jiang will visit our school next week.

That President Jiang will visit our school next week is said. ×

(2）It happens/occurs…結構中的主語從句不可提前。例如：

It occurred to him that he failed in the examination.

That he failed in the examination occurred to him. ×

(3）It doesn’t matter how/whether …結構中的主語從句不可提前。例如：

It doesn’t matter whether he is wrong or not.

Whether he is wrong or not doesn’t matter. ×

(4）含主語從句的復合句是疑問句時，主語從句不可提前。例如：

Is it likely that it will rain in the evening?

Is that will rain in the evening likely? ×

(5) if引導的主語從句

Does it matter if he can’t finish the job on time?

If she likes the present is not clear to me. ×

1．I don’t know what I was thinking of. I wonder if I might give you a necklace. .

2. I expect （that）I shall be back on Sunday.

3. He doesn’t want it to be known that he is going away.

4. I consider it necessary that he should do it again.

5. I don’t think he will see you. I don’t believe he will go.

6. We don’t expect he is coming. I don’t think he can do it, can he?

7. I don’t think he can do it, can he? I don’t think you are right, are you?

8. I insisted that he （should）do it at once. She suggested that the work （should）be finished at once.

9. The teacher is satisfied with what I said.

10. I’m afraid that I will be late. I’m glad that you passed the exam.

2、賓語從句

在復合句中用作賓語的從句是賓語從句

1） 作動詞賓語

在口語中，that引導賓語從句時常常省略。但兩個that從句并列時后邊的that一般不省略。

若有補語，則賓語從句要放到補語之后，在賓補前用形式賓語it.

在think, believe, suppose, expect等動詞之后，賓語從句中謂語的否定常轉移到主句的謂語上。如：

注：此種用法主句的主語必須是第一人稱I或we. 而且它的反意疑問句的助動詞由從句的助動詞來定。

在suggest, insist, demand, order, require 等表示建議，命令，要求的動詞后，從句的謂語動詞要用虛擬語氣。如：

2） 作介詞賓語

3） 作afraid, glad, certain, sure等形容詞的賓語。

1. The rumour that there will be an earthquake soon spread all over the area.

2. They have no hope that he will recover.

3. I have no idea where they have gone.

4. Suddenly the thought came to me that he could go blind.

比較：The news that our team won the game is true.

The news that you have heard isn’t true.

The news is that our team won the game.

3．同位語從句

如果擔任同位語的是個句子，則這個句子是同位語從句。同位語從句表示先行名詞的具體內容，能跟同位語從句的名詞常見的有news, idea, belief, doubt, fact, rumour, question, order, hope, thought, reply, problem, reason等。

引導同位語從句常用連詞that，它在句中不擔任句子成分，沒有詞意。除that外，還有whether, when, where, who, what, which, why, how等�？梢砸龑�同位語從句。同位語從句與先行名詞有時也可以分開。

注：同位語從句與定語從句的區別：

（1）同位語從句的先行名詞極為有限，而定語從句的先行詞則不計其數。

（2）引導同位語從句的連詞that在句中不擔任句子成分，而引導定語從句的that則在從句中作主語，賓語等。引導同位語從句的wh一詞多具有疑問意義，而引導定語從句的wh一詞則沒有疑問意義。

（3）同位語從句與先行名詞是等同關系，一個具體，一個抽象，兩者�？梢赞D述為主表關系，而定語從句與先行詞是修飾與被修飾關系。

（4）when和where引導的同位語從句與定語從句的區別。

when 和where前面的名詞若是表示時間、地點的名詞，則when和where引導的是定語從句，否則則為同位語從句。如：

They put forward the question where they could get the money.

This is the place where the accident happened.

1. The problem is where we can hold our meeting 問題是我們可以在哪兒舉行會議。

2. It seems that everything goes smoothly .似乎一切都進行得很順利。

3. The cause is that the temperature of water is lower that needed .

其原因是水的溫度低于所需要的溫度。

4. That is what he really wants .那就是他真想要的東西。

4．表語從句

在句子中擔當表語的主謂結構稱之為表語從句。它常位于句中聯系動詞或是起聯系動詞作用的動詞之后.

1. be, seem, look等動詞后均可跟表語從句：

It seems that it is going to rain.

It looks as if it is going to rain.

2. as if, because 也可引導表語從句。

It was because I got up late.

二、名詞性從句 難點強化

1：表命令建議 的名詞后的表語從句。

在order,(命令），suggestion, advice(建議）等的名詞后的表語從句中，謂語動詞要用虛擬語氣，即：”should+動詞原形“，should �？墒　�

如：His suggestion is that we (should) hold another meeting to discuss the problem.

2.that.whether的區別: that 用于表示肯定的意義，而whether表疑問。

I don’t doubt that he will win. (I’m sure)

It doesn’t matter

It makes no difference

It is uncertain

It is not made clear

It is still a question

It is not decided whether

It is to be found out

It is to be decided

I doubt/wonder/

have no idea/don’t know

3:名詞性從句皆用陳述語序。

I wonder how much this pair of shoes costs.

I want to know where you had put my pen.

時態 :(與間接引語基本一致)

如果主句是現在時，從句時態可以不變，但如果主句是過去的時態，那么從句的時態一定要用相對應的過去的某種時態。當從句是客觀真理,定義、公理、定理時用一般現在時。

賓： I know he lives here.

He asked whether his father would come back.

The teacher said that the earth travels around the sun.

表：That is what I was worried about two days ago.

It looked as if it was going to rain.

4:that 的省略

that引導名詞性從句時只起連接從句的作用,本身沒有任何意義,因此在從句中不充當任何句子成分,它的使用須注意以下幾點:

①主語從句、表語從句、同位語從句中用that但不能省略。如：

That they are good at English is known to us all.

The problem is that we don’t have enough money.

She expressed the hope that they would come to China one day.

②賓語從句中的連接詞that有時可省有時又不可省，在以下幾種情況中that不能省略：（A）當that從句和主句謂語動詞之間有插入詞語或者從句主語之間有插入語時，that不可省略；（B）當that 從句與另一名詞性從句并列作賓語時，that不能��；（C）當that作介詞賓語時，that不可省掉。如：

He judged that, because he was a child, he did not understand wine.

Everyone knew what happened and that she was worried.

The reason lies in that she works harder than the others do.

D.當主語為the reason時,注意應用that 引導其表語從句,不能受漢語影響而誤用because。例如:

The reason why he was late was that he missed the early bus. 他遲到的原因是他沒趕上早班車.(此句中的that不可用because代替)

③that從句作主語和賓語時，可以用it 來替換成以下幾種結構表達。

(A)It is clear/certain/likely/true/surprising that… （B）It is a pity/shame/good idea/no wonder that ...（C）It is said/reported/ believed/known/thought/suggested that … （D）It seems/happens that。如：

It happened that I went out last night.

It is said that China will win in the World Cup.

that引導主語從句位于句首時不可省略.如果it作形式主語,而that從句置于句末, 這時that可以省略。例如:

That he has lost his work is not true. 他丟了工作不是真的。

=It is not true (that) he has lost his work.

5: who, whoever, whom和whomever

在引導名詞性從句時,在句中作主語時用who,意思是"誰",含有疑問意味,whoever是它的強語勢"無論誰",不含有疑問意味。表示…..的人，相當于the person who,或anyone who

Whoever breaks the law will be punished.

注意區別：①疑問詞 + ever可引導名詞性從句，在主從句中要充當一定的部分。如：

Whoever breaks the rule must be punished.

You can choose whatever you like in the shop.

②疑問詞 + ever還可引導讓步狀語從句。如：Whatever you do, you must do it well.

( = No matter what you do, you must do it well.)

Whoever breaks the rule, he must be punished,

(=No matter who breaks the law, he will be punished.)(讓步狀語，意為無論誰）

③ no matter + 疑問詞只能引導讓步狀語從句。

作賓語時用whom, 其相應強語勢為whomever。判別時要根據句意以及在句中的語法功能來決定該用哪個引導詞。例如:

Who has taken away my bag is unknown.誰拿走了我的包還不知道。(若用Whoever顯然句意不通)

Whoever wants to see this film can go with us tonight. 無論誰想看這部電影今晚可以和我們一起去.(Whoever wants 相當于Anybody who wants,意為"凡是想……的人"。這里不可換為Who。)

Have you decided whom you are to nominate as your candidate? 你們是否已經決定提名誰作候選人了?

You can give the ticket to whomever you like. 你可以把票給任何你想給的人。

6：because引導的表語從句

Because 可以引導表語從句，但通常只用于”This/That/It i/was because…”結構中

注意：在表語從句中,當reason做主語時,引導詞只能用that,不能用because, 即the reason is that the reason (why…) is that如:

The reason was that he didn’t catch the early bus. 原因是因為他沒有趕上早班車。

The reason why he is absent from work is that he is seriously ill.

7: 注意what/ that/ which引導詞與定語從句的引導詞的區別

what與which引導名詞性從句時都在從句中充當句子的某一成份,如主語、表語、賓語或定語。

what 表示泛指的事物,常譯為"什么"或"所……的事物",

what=all that, everything that在從句中作主，賓，表語。

I don’t believe what he said.(＝I don’t believe all that he said.)

whatever是它的強語勢"無論什么"; 不能引導定語從句。

E.g: I believe what (whatever) he says. 我相信他說的(不管他說什么我都相信)。

that在所有的名詞性從句中都不作任何成分。

That he is to take charge of our factory is already an open secret.

which表示特定事物中的"哪一個(些)",一般情況下在從句中充當定語,后接名詞,在一定的語境中,它所修飾的名詞可以省略,whichever是它的強語勢"無論哪一個(些)"。 在名詞性從句中加上名詞做主語\賓語 eg: I don’t know which answer is right.

•I will give her which (whichever) book she likes on the shelf. 這個書架上的(任何一本)書,只要她喜歡,我都會給她。

在定語從句中，單獨做主語\賓語 eg: I see a film which was popular in the past.

that 引導名詞性從句時，在主從句中不以當任何句子成分，也沒有任何含義；eg: I knew that I was wrong. 在定語從句中 作賓語\主語 eg: I get the very news that is important to me.
