名词性从句
名词性从句
一、名词性从句定义：
名词性从句是由if, whether, that, how和各种疑问词充当连接词所引导的从句，其功能同名词一样。
二、类型：主语从句、表语从句、宾语从句、同位语从句
(请说出以下句子中的画线部分在句子中充当的成分)
1. When we’ll hold the sports meeting has not been decided yet.
2.The fact that Great Britain is made up of three countries is still unknown to many people..
3.He wonder if he could use my bike.

9. It is not clear whether she will attend his wedding.
10. I have no idea when he would return.
三、用法：
1、主语从句：在复合句中做主句的主语。引导词有连词that (that 不可省),whether; 代词有who, what ,which; 副词when ,where, how, why 等。如:
A. That he is a famous singer is known to us. (It is known to us that he is a famous singer.)
B. When he will go to America is not yet fixed. (It is not yet fixed when he will go to America.)
2. 宾语从句：在复合句中做主句的宾语.引导词有连词that (that 常可省略),whether, if; 代词有who, whose, what ,which; 副词when ,where, how, why 等。如:
A. We believe (that) he is honest.
B. I told him (that) I would come back soon.
C. He said (that) he would go there the next day and that his family wouldn’t go there.
3、表语从句：在复合句中做主句的表语.引导词有连词that (that 不可省),whether; 代词有who, what ,which;副词when ,where, how, why 等。如:
A. The problem is that we didn’t get in touch with him.
B. This is how Henry solved the problem.
C. His suggestion is that we (should) finish the work at once.
(如果句子的主语是suggestion, advice, order等名词时,后面引导的表语从句用should+动词原形,should可省略.)
4、同位语从句：在句中起同位语的作用.一般放在名词fact , news , idea , promise, thought , suggestion等之后,用以说明或解释前面的名词。引导词有连that；少数情况下也可用连接副词等。如：
A. The thought that we might succeed excited us.
B. The idea that they should try a second time is worth considering.
C. The suggestion that the plan (should) be delayed will be discussed tomorrow.
(如果名词suggestion,advice.order等词后的同位语从句的谓语动词要用should+动词原形,should可省略.)
四、注意：
1、注意that 的用法(that引导名词性从句时在从句中不做任何成分，也没有具体的意义。其他连接词在引导从句时都做相应的成分并有具体的意思。)
①主语从句、表语从句、同位语从句中用that但不能省略。如：
A. That they are good at English is known to us all.
B. The problem is that we don’t have enough money.
C. She expressed the hope that they would come to China one day.
②宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：
当从句和主句谓语动词之间有插入词语或者从句主谓之间有插入语时，that不可省略；
当that从句与另一名词性从句并列作宾语时，that不能省；
当that作介词宾语时，that不可省掉。如
A. He judged that, because he was a child,he did not understand what he had said.
B.I believe that he, as a teacher, is responsible
C. Everyone knew what happened and that she was worried.
D. The reason lies in that she works harder than the others do.
③that从句做主语和宾语时，可以用it来替换成以下几种结构表达。
(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
2、注意同位语从句和定语从句的区别：
A.从句前都有一个名词
B.定语从句中关系词代替先行词在从句中做成分;而在同位语从句中连接词不做成分。
C.定语从句是对前面的名词进行修饰，同位语从句是对前面的名词进行解释说明。
The news that our team has won the final match is encouraging.
（同位语从句）我们队取得决赛胜利的消息令人鼓舞。
The news that you told us is really encouraging.
（定语从句）你告诉我们的消息真的令人鼓舞
The suggestion that students should learn something practical is worth considering.
The suggestion that is worth considering is that the students should learn something practical.
They put forward the question where they could get the money.
This is the place where the accident happened.
3、whether和if的用法
①whether和if在宾语从句中可以互换，但是作介词宾语时连接词一般用whether。
如：It all depends on whether they will come back.
②后面直接跟or not时用whether
如：I didn’t know whether or not he had arrived in Wuhan..
③主语从句，表语从句，同位语从句中只能用whether。如：
Whether the meeting will be put off has not been decided yet.
The question is whether they have so much money.
We ought to discuss carefully the question whether we can do it or not.
④whether常与or连用表示一种选择，if不能这样用；whether也可与动词不定式连用但if不能。如：
The question of whether they are male or female is not important.
I have not decided whether to go or not.
⑤whether可引导一个让步状语从句表示“不管”、“无论”，而if不能。If表示“如果”时，不能用whether。如：
Whether he comes or not,we will begin our party on time.
If I have enough time, I will play football.
4、疑问词+ever和no matter+疑问词的区别：
①疑问词+ever可引导名词性从句，在主从句中要充当一定的部分。如：
Whoever breaks the rule must be punished.
You can choose whatever you like in the shop.
②疑问词+ever还可引导让步状语从句。如：
Whoever breaks the rule,he must be punished.
Whatever you do,you must do it well.
③no matter+疑问词只能引导让步状语从句。如：
No matter what you do,you must do it well.
No matter who breaks the rule,he must be punished.
5、名词性从句中主句和从句的时态一致、主谓一致、语序。
①宾语从句中主句和从句的时态保持一致，但如果从句中表示提示的是客观现象，虽然主句是过去时态，从句仍用一般现在时。如：
Hello,I didn’t know you were in London.
How long have you been here?
The teacher told us that light travels at a very high speed.
②主语从句做主语相当于单数第三人称作主语，谓语动词用单数，如果由and连接两个或两个以上的主语从句做主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。如：
When the meeting will begin has not been decided yet.
When they will start and where they go have not been decided yet.
When and where the meeting will begin has not been decided.
③名词性从句在句中要用陈述句语序。如：
We’ve heard the news that we’ll move into the new house.
Whatever you say will interest us all.
He asked me what was the matter with me.
6、几个固定句式：
①强调句It is/was +强调部分＋that…….(如果强调部分是疑问词)
eg. Who is it that spoke first? When was it that they came here?
②关于doubt
sb. doubt if/whether… sb. don’t/doesn’t doubt that … There is no doubt that …
eg. There is no doubt that he will win the game.
③疑问词＋do you think+(用陈述句语序)
eg. Who do you think we invited to give us the talk?
④表语从句：A is to B what C is to D A对于B就像C对于D
e.g. Engines are to machines what hearts are to animals.
⑤表语从句：the reason for sth. is that…
The reason why +从句is that …
五、名词性从句连接词的选用
（1）that 和what 的选用
1.______ he wants is a book.
2. ______ he wants to go there is obvious.
3.The result is ______ we won the game.
4.This is _____ we want to know.
5.Is _____ he told us true ?

我不知道他长的什么样子。I have no idea _________ he looks like.
这就是我忘记眼镜的地方。This is _________ I left my glasses.

2.It is a pity ________ he has made such a mistake.
3.The reason is _________ he is careless .
4.The news ________ our team won the match inspired us.
5.I don’t think it necessary _________ you should read English aloud.
6.He told me __________ his father had died and __________ he had to make a living alone.
六、同位语从句的引导和辨别t hat/ whether / where/ how
1. I have no idea _________ he comes from.
2. He can’t answer the question ________ he got the money.
3. He gave us many suggestions ________ we should get up earlier and take more exercise.
4. I have no doubt ___ he will win.
5. I have some doubt ____ he will win.
同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that 引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
1.We expressed the hope that they had expressed.
2. We expressed the hope that they would come to China again.
3. The information has been announced that more middle school graduates will be admitted into university.
4. The information that he revealed at the meeting is of great value.

He looked just as he had looked ten years before. 他看起来还与十年前一样。 2. The question is whether they will be able to help us. 问题是他们是否能帮我们。 注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如：All this was over twenty years ago, but it’s as if it was only yesterday. 这都是20多年前的事了，但宛如昨天一样。 注：能跟表语从句的谓语动词一般为系动词be, seem, look，sound等。如：He looked just as he had looked ten years before. 他看起来还与十年前一样。(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever 在 表语从句中做主语、宾语等。如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。 That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 (4)连接副词where, when, how, why。 What I wonder is when he left. 我想知道他是何时离开的。 This is where they once lived. 这就是他们曾经住过的地方。 (5)连词because可引导表语从句。如： I think it is because you are doing too much. 我想这是因为你做得太多。 That's because he didn't understand me. 那是因为他没有理解我。(That's because...强调原因) That's why he got angry with me. 那正是他对我生气的原因。 (That's why...强调结果) (6)解释： 2．在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。 同位语从句 一、理解同位语从句的含义，把握同位语从句的实质 在主从复合句中作同位语的从句称为同位语从句。同位语从句一般用that, whether，what, which, who, when, where, why, how 等词引导，常放在fact, news, idea, truth, hope, problem, information, wish,promise, answer, evidence, report, explanation, suggestion, conclusion等抽象名

名词性从句知识点总结
名词性从句 名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。 （一）引导名词性从句的连接词 1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 注意： 1、连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。 2、不可省略的连词： （1）介词后的连词 （2）引导主语从句和同位语从句的连词不可省略。 That she was chosen made us very happy. We heard the news that our team had won. （二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesn’t matter so much whether you will come or not. 主要句型有： （1）It+be+形容词+that从句。 It is probable that he told her everything. 很可能他把一切都告诉她了。 （2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。 （3）It+be+过去分词+that从句。 It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。 （4）It+seem, happen等不及物动词及短语+that从句。 It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。 （5）It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。 It doesn’t matter whether she will come or not. 她是否来这无关紧要。 It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。 3、that引导主语从句时，不能省略。 e.g. That he suddenly fell ill last week made us surprised. 4、当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。 What we need is more time and money. What we need are many more books. 5、if不能用在主语从句中，而是用whether Whether he left (or not) is unknown 6、引导主语从句的关联词有三类： (1)从属连词that。
