什么叫名词性从句？
在句子中起名词作用的句子叫名词从句 (Noun Clauses）
名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语等
因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句

1.They are good doctors. He told us. →
2. He hadn’t said anything at the meeting. The fact surprised us.→

4.Do animals have the same senses as humans I often wonder. →
Do you know if/ whether your sister gets up early

5.When did he buy this new bike Could you tell me →
6.My question is this: where will the lecture be given →

（复合句）
宾语从句的概念：
宾语从句在复合句中作主句的宾语。
句子结构：
主句 +连词（引导词）+ 宾语从句
一、连词（引导词）
1. 当宾语从句是陈述句时（包括肯定句和否定句），连词由that引导，因为that在从句中不作任何成分，也没有任何具体意思，因此在口语或非正式文体中常省略
She says (that) she won’t take part in the sports meeting next Sunday.
Jim thought (that) the train was like a big moving party.
2.宾语从句中的连接词that在以下三种情况下不能省略：
（1）当that 从句与另一名词性从句并列作宾语时，第二个that不能省；
（2）当that作介词宾语时，that不可省掉。
（3）用it做形式宾语的宾语从句
Everyone knew what happened and that she was worried.
The reason lies in that she works harder than the others do.
I think it necessary that you should read English aloud.
在主句为动词be加某些形容词（如sorry, sure, afraid, glad等）作表语时，后面所跟的省略that的从句也可算是宾语从句
I’m sorry (that) I don’t know .
We’re sure (that) our team will win .
I’m afraid (that) he won’t pass the exam .
2. 当宾语从句是一般疑问句时，由连词whether或if引导（口语中常用if），因为if/whether翻译成：“是否”，具有一定的意义，所以不能省略
Lily wanted to know if /whether her grandma
liked the handbag .
Let’s see if /whether we can find out some
information about that city .
She asked me if /whether she could borrow
these books .
whether与if的辨用
表“是否”时，在下列情况下用whether。
a. 主语从句 b. 表语从句 c. 同位语从句 d. 介词后的宾语从句 e.后接动词不定式 (whether to do sth.) f .whether or not 连在一起引导宾语从句时不用if
Practice time
if / whether 1. I asked her __________ she had a bike. 3. We’re worried about ________ he is safe. 4. I don’t know ___________ he is well or not. 5. I don’t know ________ or not he is well. 8. I don’t know _______ to go.
if / whether
whether
whether /if
whether
whether
3. 当宾语从句是特殊疑问句时，由连接代词（what, who, whom, which, whose）或连接副词（when, where, how, why）引导，因为连接代词或连接副词在从句中担任一定的句子成分，具有一定的意义，所以不可以省略
Do you know what he said just now
I don’t remember when we arrived .
I asked him where I could get so much money .
Please tell me who (whom) we have to see .
Do you know what time the plane leaves
带how的词组也都可以引导宾语从句
Could you tell us how often you go abroad for a holiday
Could you tell us how long the meeting will last
I don’t know how far it is to the cinema .
Please tell us how many students there are in your school
Can you tell us how old his brother is
Please tell us how soon you will be ready .
Could you tell us how much it costs to fly to Hainan
二、时态
1. 如果主句是现在的时态 （包括一般现在时 ，
现在进行时，现在完成时），从句的时态可根
据实际情况而定，（包括一般现在时，一般过
去时，一般将来时，现在完成时等）
I know he lives here .
I know he lived here ten years ago .
I have heard that he will come tomorrow .
2.如果主句是过去的时态（包括一般过去时，过去进行时），那么从句的时态一定要用相对应的过去的某种时态（包括一般过去时，过去进行时，过去将来时， 过去完成时）
I knew who lived here.
I saw she was talking with her mother.
He asked whether his father would come back
tomorrow.
He said that he had seen it .
3.当从句是客观真理，定义，公理，定理
时用一般现在时。
The teacher said that the sun travels
around the earth .
The radio says it _______ cloudy tomorrow. (be)
The headmaster hopes everything ______ well. (go)
Tom says that they _________ (play) basketball at six o’clock yesterday evening.
I hear they __________ (return) it already.
He said that they _________ members of the Party since 1948. (be)
will be
goes
were playing
have returned
had been
6. I didn’t know what time he _______ the letter. (write)
7. Could you tell me who _________ away the book already (take)
8. Ling Feng told me he _________ to the Great Wall several times. (be)
wrote
has taken
had been
三、语序
宾语从句的语序用陈述语序：
连接词+主语+谓语+其他成分
1. When will he go to the library
His brother asks when he will go to the library .
His brother asks when will he go to the library .
2. What does he want to buy
I don’t know what he wants to buy .
I don’t know what does he want to buy .


1．could / would是委婉语气，而不是过去式，因此宾语从句的时态根据实际情况用不同时态。
注意事项
Could you please tell me where we show our
tickets
Could you tell us which gate we have to go to
Would you like to know when he will come back
2. 如果主句的谓语动词是ask时，连词不可能是that；如果主句的谓语动词是say时，连词用that
She says (that) she will leave a message on
his desk .
He said (that) he was going to take care of
the child .
He asks if I like playing the piano .
You may ask the man over there how you
can get to the bus station .
3. 否定的转移:若主语谓语动词为think, consider, suppose, believe, expect, guess, imagine等,其后的宾语从句若含有否定意义,一般要把否定词转移到主句谓语上,从句谓语用肯定式。
I don’t think this dress fits you well. (我认为这件衣服不适合你穿。)
4. it常可以放在动词think, find, consider, believe, feel, make等后作为形式宾语:it不仅可以作为形式主语，还可以作为形式宾语而真正的宾语-that从句则放在句尾,特别是在带复合宾语的句子中。 We heard it that she would get married next month.
Predicative Clauses
表语从句
表语从句是在复合句中作表语的名词性从句, 放在系动词之后,一般结构是“主语+系动词+表语从句”。可以接表语从句的系动词有be, look, remain, seem等。另外,常用的还有the reason why … is that … 和It is because …等结构。例如：
. 表语从句：从句在句中充当表语成分，一般放在连系动词之后. 作用:对主语进行解释说明。
连接词：that / whether /as if /as though（ if 不 引导 表语从句)
连接代词：who / whom / whose / which / what
连接副词：when / where / why / how / because
The question is whether we can rely on him.
That’s because we were in need of money at that time .
He looked as if he was going to cry .
That’s why I was late .
注 意：
在表语从句中，表“是否” 时，只能用 “whether”不能用“If”。
一般情况下，“that”不能省。
It is /was because ….
It is /was why….
3. The reason (why…/for…)is /was that….
4 The reason is because /why…
that ….
名词主语+be+that引起的表语从句
在这种句型中，常用表示事实，真理的名词，如：fact, truth 或表示看法，观点的名词，如：idea,opinion,belief,view,feeling,suggestion,plan等作主语。
如：
1.The fact is that our team has won the game.
2.The truth is that she was the very person who informed against her husband.
注意
表语从句的引导词与主语从句和宾语从句相同.
但: 1. that引导表语从句时不能省.
2. if不能引导表语从句.
1. That’s ___ the Party called on us to do.
A. why B. what C. how D. that
2. The reason is ___ he is unable to operate the machine.
A. because B. why C. that D. Whether
3 .That is ___ they separated.
A. that B. what C. which D. where
4.Jane is no longer ___ she was four years ago.

Subject Clauses
主语从句
1. 主语从句：从句在句中充当主语成分
1). That he will succeed is certain .
2) Whether he will go there is not known .
3) What he said is not true .
4) Where he hid the money is to be found out .
5) Whoever comes is welcome.
6) It’s certain that he will succeed .
7) How we can help the twins will be discussed at the meeting.
8)When they’ll start the project has not been decided yet.
考点一:主语从句后置!
为了避免主语冗长,句子头重脚轻,经常用it作形式主语,主语从句放在后面作真正的主语.
例:
That we shall be late is certain.
-- It’s certain that we shall be late.
1. That the earth is round is known to all.
--
2. That you missed the chance is a pity.
--
由连词 whether , 连接代词 what,who,which
和连接副词 when,where,why,how 等引导.也
常常后置:
It is a pity that you missed the chance.
It’s known to all that the earth is round.
It 的用法： （形式主语）
It’ possible/important/necessary/clear… that……很可能/重要的是…/必要的是…/很清楚…
It’s said/ reported… that..据说/据报道…
It’s been announced/declared that..已经通知/宣布…
It seems/appears/happens.. that…显然、明显、 碰巧..
It’s no wonder that…并不奇怪/无疑…
It’s a pity/a fact /a common knowledge (众所周知）
/ a common saying….（俗话说）
考点二
注意：主语从句中 ，谓语动词一般用单数
What引导的主语从句，可根据表语决定
What he needs _is_ that book.
What he needs _are_ some books.
what引导名词性从句时在从句中充当句子成分,如主语,宾语,表语,而that则不然,它在句子中只起连接作用。例如：
(1) What you said yesterday is right.
(2) That she is still alive is a puzzle.
What 与 that 引导主语从句
由 that 引导:
1. That we shall be late is certain.
2. _____________________ is known to all.
(地球是圆的)
3. ________________________ is a pity.
(你错过了这次机会)
that 无意义, 后接一个完整的句子.
that 不可省
That the earth is round
That you missed the chance
注 意：
What you left are only several old books.
What you said is of great importance.
What he says and does doesn’t concern me.
What he says and does don’t agree.
“if” 不能引导主语从句，应有“whether”引导。
主语从句的 “that” 一般不能省。
“what”引导主语从句时，谓语动词：
1）常与其后的名词作表语一致 2）根据句子的语境而定。
___ he made an important speech at the meeting was true.
A. That B. Why C. What D. How
2. ___we’ll go camping tomorrow depends on the weather .
A If B Whether C That D Where

A. whether B. that C. what D. when
6.What I say and think ___ none of your business.

Appositive Clauses

同位语从句在句中充当同位语从句成分，其一般跟在一些抽象名词（ idea ；belief ； fact ； truth ； problem ；news 等）后面，对名词作进一步解释说明. n.+ 连接词 + 从句
同位语从句常用 that 引导或用连接副词when / where/why / how / whether
1) The idea that computers can recognize human voices surprises many people .
2).Sydney kept his promise that he would always do anything he could for Lucie to make sure of her happiness.
注: 1. 同 位语从句多用that 引导
2. 在have no idea 之后常用wh-引导同位语从句.
I have no idea where he has gone.
I have no idea when he did it.
I have no idea what he did.
I have no idea
when he will be back.
how he can get the treasure.

______________________________________________
The fact that two thirds of all girls are on a diet
worries their parents and teachers a lot.
_________
______________________________________________
______
We heard the news last night that the Queen of
England was on a three-day visit in China.
名词demand, suggestion, proposal, advice 等词后的同位语从句的语气要用虚拟语气, 结构为 should + do, should 可省略
He gave me a suggestion that I ( should ) be calm now.
I have heard the news that he visited our factory .
I have heard the news that he told you the other day .
同位语从句和定语从句的区别：
1 同位语从句——that 只起连接作用，不作任何成分
定语从句 —— that 是关系代词，起连接作用和充 当宾语和主语
2同位语从句——同位语从句和前面的名词是同位关系，对名词进行补充说明
定语从句 ——定从和前面的名词是所属关系，对名词进行修饰，加以限定
3同位语从句——that 不能省
定语从句 ——that 在从句中作宾语时，可以省
Practice :判断下列各句是同位语从句还是定语从句
1.They expressed the hope that they would come to visit China again.
2. The hope that she expressed is that they would come to visit China again.
3.The fact that she works hard is well known
to us all.
