初中英语名词性wh从句语法大全

A. 英语名词性从句的语法知识

你这个问题太宽泛。只能选择部分回答。

有时因意思表达的需要，要用一个从句在句子中作主语、宾语、表语或同位语，称为名词性从句（包括主语从句、宾语从句、表语从句和同位语从句）。名词性从句作为一个整体，本身在整个句子中起一个名词的作用；同时既是从句，就从句内来说，也有主、谓成份。当然，从句要有引导词。

引导词的基本含义及用法
对于引导词要注意两点：a. 本身所含的意思，b. 其在从句中所充当的句子成分。据此，可以分成几类（这是我自己的办法，要比别的办法管用）
①that
②whether/if, because, as if/though
③when, how, where, why, whenever, wherever, however
④what, which, who, whom, whatever, whichever, whoever, whomever
⑤what, whatever, which, whichever, whose
1．That 既无意义，也不在句子中担任成分。
可以说只是一个“标志”，标明所跟的是一个从句而已。
That theory must go hand in hand with practice is a principle we should always keep in mind.
2．Whether/if, because, as if 本身有意义，但在从句中不担任成分。
Whether/if --“是否”；because—“因为”；as if—“似乎”
She hesitated whether she should take our advice.
All this was over twenty years ago, but it’s as if it was only yesterday.
It is because you don’t have confidence.
3．When, where, why, how, whenever, wherever, however 本身有意义，且在从句中担任状语。
When--“。。。的时间”或“何时”；whenever—“无论何时”，作时间状语
Where—“。。。的地点”或“何地”；wherever—“无论何地”，作地点状语。
Why--“。。。的原因”或“为什么”，作原因状语。
How--“。。。的方式”或“怎样”；however—“无论怎样”，作方式状语。
When we shall have our sports meet is still a question.
This is where our basic interest lies.
I don’t know why he is absent.
How the prisoner escaped was a complete mystery.
4．What, which, who, whom, whatever, whichever, whoever, whomever本身有意义，且在从句中作主语、宾语、表语。
What—“。。。的（东西、事情。。。）”或“什么”，whatever—“无论什么”，在从句中作主语、宾语、表语。
Which—“哪一个/些”，whichever—“无论哪一个/些”，在从句中作主语、宾语、表语。
Who—“谁”，whoever—“无论谁”，在从句中作主语、表语，有时也可代whom，whomever作宾语。
Whom—“谁”，whomever“无论谁”（罕用），在从句中作宾语。
She is sorry for what she said. （她所说的话）（what无疑问含义）
I don’t know what will happen next. （将发生什么事）（what有疑问含义）
I don't know which of us was the more scared. （我们中的哪一个更害怕）
They never found out who the murderer was. （谋杀者是谁）
He asked whom I'd told about his having been away. （关于他外出我告诉了谁）
He's good at whatever he is does. （他做无论什么事）
5．What, whatever, which, whichever, whose本身有意义，且在从句中作定语
What—“什么（样的）”，whatever— “无论什么（样的）。作定语。
Which—“哪个/些”，whichever—“无论哪个/些”。作定语。
Whose—“谁的”，在从句中作定语。
I wanted to know which school it was you went to. （那个学校）
I didn't know what college I wanted to go to. （什么大学）
I can't remember whose idea it was for us to meet again. （谁的主意）
Whatever doubts he might have had about Ingrid were all over now. （无论什么怀疑）
Learn to relax by whichever method suits you best. （无论什么方法）

B. 求：词性wh-从句怎么用

1）由wh-词引导的名词从句叫做名词性wh-从句。-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：
主语： How the book will sell depends on its author.
书销售如何取决于作者本人。
直接宾语：In one's own home one can do what one likes.
在自己家里可以随心所欲。
间接宾语：The club will give whoever wins a prize.
俱乐部将给得胜者设奖。
表语： My question is who will take over president of the Foundation.
我的问题是谁将接任该基金会主席职位。
宾语补足语：She will name him whatever she wants to.
她高兴给他起什么名字就取什么名字。
同位语： I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语：I'm not sure why she refused their invitation.
我尚不能肯定她为什么拒绝他们的邀请。
介词宾语： That depends on where we shall go.
那取决于我们去哪儿。
2）Wh-从句作主语也常用先行词it做形式主语，而将wh-从句置于句末，例如：
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married. 他们何时结婚依然不明。

祝你学习进步，更上一层楼！请记得采纳，谢谢！(*^__^*)

C. WH 名词性从句

引导主语从句，要用what。What was even more surprising to him.

D. 求what,where,who之类wh-的从句用法！！本人学习不久，不要讲太深奥了！

大体上与宾语从句相同，要求陈述语序，如：
What he said means nothing.
但是，由陈述句变化而来的主语从句必须用that引导，如：
That the weather will grow from bad to worse discouraged all the villagers.
由陈述句变化而来的主语从句常常译为“...这件事”。

17.1 引导名词性从句的连接词

引导名词性从句的连接词可分为三类：
连接词：that,whether,if 不充当从句的任何成分）
连接代词：what, whatever, who, whoever, whom,
whose, which.
连接副词：when, where, how, why
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.
比较：whether与if 均为"是否"的意思。 但在下列情况下，whether 不能被if 取代：
1. whether引导主语从句并在句首
2. 引导表语从句
3. whether从句作介词宾语
4. 从句后有"or not"
Whether he will come is not clear.

大部分连接词引导的主语从句都可以置于句末，用 it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.

17.2 名词性that-从句

1）由从属连词that引导的从句叫做名词性that-从句。 That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语，例如：
主语：That he is still alive is sheer luck. 他还活着全靠运气。
宾语：John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。
表语：The fact is that he has not been seen recently. 事实是近来谁也没有见过他。
同位语：The fact that he has not been seen recently disturbs everyone in his office.
近来谁也没有见过他，这一事实令办公室所有的人不安。
形容词宾语：I am glad that you are satisfied with your job.
你对工作满意我感到很高兴。

2）That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：
It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。
It's a pity that you should have to leave. 你非走不可真是件憾事。

用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be +形容词+ that-从句
It is necessary that… 有必要……
It is important that… 重要的是……
It is obvious that… 很明显……

17.3 名词性wh-从句

1）由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：

主语： How the book will sell depends on its author. 书销售如何取决于作者本人。

直接宾语：In one's own home one can do what one likes. 在自己家里可以随心所欲。

间接宾语：The club will give whoever wins a prize.
俱乐部将给得胜者设奖。

表语： My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。

宾语补足语：She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。

同位语： I have no idea when he will return.
我不知道他什么时候回来。

形容词宾语：I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。

介词宾语： That depends on where we shall go.
那取决于我们去哪儿。

2）Wh-从句作主语也常用先行词it做形式主语，而将wh-从句置于句末，例如：
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married. 他们何时结婚依然不明。

17.4 if, whether引导的名词从句

1）yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的，因此也分别被称为yes-no型疑问句从句和选择型疑问从句，其功能和wh-从句的功能相同， 例如：
主语：Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。

宾语：Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。

表语：The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。

同位语：They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。

形容词宾语： She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。

介词宾语： I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。

2）选择性疑问从句
选择性疑问从句由关联词if/whether…or或whethe…or not构成，例如：
Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。

17.5 否定转移

1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I don't think I know you. 我想我并不认识你。
I don' t believe he will come. 我相信他不回来。
注意：若谓语动词为hope,宾语从句中的否定词不能转移。
I hope you weren't ill. 我想你没有生病吧。

2) 将seem, appear 等后的从句的否定转移到前面。
It doesn't seem that they know where to go.
看来他们不知道往哪去。
It doesn't appear that we'll have a sunny day tomorrow.
看来我们明天不会碰上好天气。

3) 有时将动名词，介词短语或整个从句的否定转变为对谓语动词的否定。
I don't remember having ever seen such a man.
我记得从未见过这样一个人。 (not否定动名词短语 having…)
It's not a place where anyone would expect to see strange characters on the street.
在这里，人们不会想到在街上会碰上陌生的人。
(anyone 作主语，从句中的谓语动词不能用否定形式。)

4) 有时状语或状语从句中否定可以转移到谓语动词前。
The ant is not gathering this for itself alone. (否定状语) 蚂蚁不只是为自己采食。

主语从句：that, whether, wh-, how, -ever
宾语从句：that, whether, if，wh-, how, -ever
介词后的宾从：that, whether, wh-, how, -ever
形容词后宾从：that, whether, if，wh-, how

地点状语从句：where,wherever,anywhere,everywhere
原因状语从句：because,since, as, for
目的状语从句： so that, in order that,in case
结果状语从句：so...that, such...that
条件状语从句：if, unless, if only, so long as, in case
让步状语从句：though, even though, while, whereas -ever
比较状语从句：as...as, than, the+比较级...the＋比较级...

句型结构

句子按其结构可分为简单句、并列句和复合句。

1、简单句

基本形式：简单句的基本形式是由一个主语加一个谓语构成。其它各种句子形式都是由此句型发展而来，如五大基本句型：

（1）主语+谓语（s.+predicate）

这种句型简称为主谓结构，其谓语一般都是不及物动词，例：Things change.事物是变化的。Nobody went.没有人去。

（2）主语+系动词+表语（s.+link v.+predicative）

这种句型称为主系表结构，其实联系动词在形式上也是一种谓语动词，系动词与表语一起构成了复合谓语，例：Mr. Turner is an artist.特纳先生是位画家。

（3）主语+谓语+宾语（s.+predicate+o.）

这种句型可称为主谓宾结构，它的谓语一般多是及物动词，例：We never beat children.我们从来不打孩子。

（4）主语+谓语+间接宾语+直接宾语（s.+predicate+oi.+od.）

这种句型可称为主谓宾宾结构，其谓语应是可有双宾语的及物动词，两个宾语一个是间接宾语，一个是直接宾语，例：He gave the book to his sister.他把这本书给了他的妹妹。

（5）主语+谓语+宾语+宾语补足语（s.+predicate+o.+o.c.）

这种句型可简称为主谓宾补结构，其补语是宾语补语，与宾语一起即构成复合宾语，例：I found the book easy.我发现这本书不难。（形容词easy作补语）

注意：有时两个或更多的并列主语拥有一个共同的谓语，甚至并列有两个主语和两个谓语，这样的句子仍然是简单句，例：China and other countries in the east Asia are developing rapidly.

中国和东亚其它国家正在迅速地发展。（China and other countries并列主语）

2、It引导结构

It 既是代词又是引词。作代词时，它可做人称代词、指示代词、非人称代词，用于前指、非确指或习语中。作引词时，它本身无实义，只起先行引导的作用。

可作形式主语（it is + adj. + for/of sb. to do sth.）或形式宾语（it + adj. + to do sth.），真实的主语或宾语是不定式、动名词或名词从句，它们则放在后面。

It 也用于强调句结构。如想强调某个词或部分，可用it is (was) + 强调部分（主语、宾语或状语） + that(who）…的强调结构。本章要求了解代词it 和引词it 的各种用法，重点掌握it 用于前指或后指；引导词it 用于强调结构。

3、并列句

两个或两个以上的简单句用并列连词连在一起构成的句子，叫做并列句，其基本结构是“简单句+并列连词+简单句”。

并列连词有：and, but, or, so等。并列句是由两个或两个以上的简单句连接而成。并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连词连结。

4、复合句

复杂句（Complex Sentence）由一个主句（Principal Clause）和一个或一个以上的从句（Subordinate Clause）构成。

主句是全句的主体，通常可以独立存在；从句则是一个句子成分，不能独立存在。

从句不能单独成句，但它也有主语部分和谓语部分，就像一个句子一样。所不同在于，从句须由一个关联词（connective）引导。

G. 英语中从句的语法大全

英语中六大从句用法总结
1.主语从句
1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.
3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.
2.宾语从句
1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。
He didn't think that the money was well spent.
3.表语从句
表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.
The reason why so many people died there is that there were not enough food supplies.
It looks as if successful international cultural communication will make the world smaller.
4.同位语从句
同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。
She finally made the decision that she would join the fashion show.
I had no idea how many books I could borrow at a time.
The news came that their team had won the championship.
5.定语从句
定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。
*限制性定语从句
限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)关系代词的省略
在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。
This is one of those things with which we have to put up.
This is one of those things (which\that) we have to put up with.
3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
5.定语从句
*非限制性定语从句
非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.
*“介词+which\whom\whose”引导的定语从句
“介词+which\whom\whose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中，代替先行词是人或物的名词。as引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。
These are not such problems as can be easily solved.(as代替先行词problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)
6.状语从句
*时间状语从句
引导时间状语从句的从属连词和词组有：
1）when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。
As soon as I sent an e-mail message,I received positive responses.
The moment he heard the good news,he jumped with joy.
*地点状语从句
引导地点状语从句的连词是where,wherever.
Wherever she went,she took her little daughter with her.
*原因、结果和目的状语从句
1）引导原因状语从句的从属连词有：because,as,since,now(that),seeing that,considering that,in that等。
Considering that he is a freshman,we must say he is doing well.
2)引导结果状语从句的连词有：so...that,such...that

H. 【初中语法题】【wh-从句】是跟【不定式】还是【陈述句】★ 在线等~

只有名词性的 wh 才能 跟 to do 因为 do 什么 ，？？ 不就是 do wh 。。也就是说 wh to do 。。这个 do 的宾语是 前面的 wh 。。。。第二题的when很明显是个状语性的代词，，也可以说是个副词性的，请问我怎么do 一个副词。。。。。

而 第一题的what很明显是名词性的。。。。可以do 它。。

我真晕，我看了几遍，第二个问题的答案是A的原因是因为时态的缘故，而不在不定式。to do 是将来时的。。。。不好意思，，你这个分给下面的人吧。。。呵呵
编-忍 10:51:58
why 不可跟 to do 这是 约定俗成的 语法。。。。其他的都可以跟 to do 句型。。。。你做题的时候，一定要检测to do 后面有没有宾语，如果有，则前面的引导词就必须是副词性质的；如果没有，前面的引导词就必须是代词或是名词性质的。when to start the meeting 这句话没有什么错误，只是在这里不符合时态而已。。仅此而已。。。。。。呵呵

I. 求有关动词+Wh-从句的资料

1.3 名词性wh-从句
1）由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：
主语： How the book will sell depends on its author. 书销售如何取决于作者本人。
直接宾语：In one's own home one can do what one likes. 在自己家里可以随心所欲。
间接宾语：The club will give whoever wins a prize.
俱乐部将给得胜者设奖。
表语： My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。
宾语补足语：She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。
同位语： I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语：I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。
介词宾语： That depends on where we shall go.
那取决于我们去哪儿。
2）Wh-从句作主语也常用先行词it做形式主语，而将wh-从句置于句末，例如：
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married. 他们何时结婚依然不明。
