名词性从句考点大全
名词性从句
名词性从句引导词的基本用法：
（一）概念：名词性从句是指可以像名词一样在句子中充当主语、表语、宾语、同位语的从句。对于名词性从句，首先要从整体上把握其基本形式，了解各种引导词的使用方法。其次，要分别了解主语从句、表语从句、宾语从句、同位语从句各自的一些特征。
（二）名词性从句的引导词
名词性从句的引导词引导词是否在名词性
从句中充当成分的情况
连接代词：what, which, who, whom, whose
连接副词：when, where, why, how, what, which在从句中作主语、宾语、表语或定语；who在从句中作主语、表语；whom在从句中作宾语；whose在从句中作定语；when, where, why, how在从句中分别作时间状语、地点状语、原因状语、方式状语
连词: that;whether, if否
名词性从句的引导词：
1. 引导特殊疑问句的疑问词在转为引导名词性从句时，即成为连接代词(主要包括what, which,
who, whom, whose)或者连接副词(主要包括when, where, why, how)。
注意体会如下例句：Choose which you like best. 选你最喜欢的。
// Who has taken away my bag is unknown. 谁
拿走了我的包还不知道。
// Have you decided whom you are to nominate as your candidate? 你们是否已经决定提名谁做候选人了?/
/ He asked when Mr. Gilbert would be allowed
to go home. 他问什么时候可以允许吉尔伯特先生回家。
// Where we can look up his address is still a problem. 我们在哪儿可以查到他的地址还是个难题。
// Why he did that wasn't quite clear. 他为什么做那件事还不十分清楚。
// How they will solve the serious problem has not been decided. 他们将怎样解决这个严重问
题还没有决定。
以下两种特殊情况要给予特别关注：
(1)what作连接代词引导的名词性从句既可
以表示一个问“什么……？”的问题，也可以表示相当于“名词/代词＋关系代词引导的定语从句”结构的意思，这种特殊用法在语法上被称作“关系代词型的what”，注意体会如下例句：He is not what (=the person that) he was a few years ago. 他不是几年前的他了。
// This is what (=the place that) they call Salt Lake City. 这就是他们称作盐湖城的地方。
// What (=the place that) is now the North Sahara Desert was once a civilized world. 现在的北部撒哈拉沙漠曾是一个文明世界。
// Our income is now double what (=the income that) it was ten years ago. 我们现在的收入是十年前的两倍。
// The color of the flower is different from what (=the color that) it was in the morning. 花朵(现在的)颜色与它早上的颜色不同。
(2) 带'ever后缀的疑问词除引导让步状语从句之外，还可以引导名词性从句(“no matter ＋疑问词”的结构只能引导让步状语从句，不可以引导名词性从句)，注意体会以下例句：Whoever wants to see this film can go with us
tonight.无论谁想看这部电影，今晚都可以和我们一起去。
// You can give the ticket to whomever you like. 你可以把票给任何你想给的人。
// All the books are here. You may borrow whichever (book) you like. 所有的书都在这儿，你愿借哪本就借哪本。
// I'll do whatever you ask me to do. 你叫我做什么，我就做什么。
2. that引导名词性从句时后面接完整的陈述句，that只起引导名词性从句的作用而不充当该名词性从句中的具体成分；引导宾语从句时that常可省略，但引导主语从句、表语从句、同位语从句时that通常不被省略。例如：She hoped (that) he would arrive on time. 她希望他按时到达。(宾语从句)
That she was chosen made us very happy. 她被选中了让我们很开心。(主语从句)
I have the belief that I will succeed. 我怀有必胜的信念。(同位语从句)
that，what引导名词性从句的区别在于：that在其引导的名词性从句中不充当任何成分，
在有的情况下可以省略；what需要在其引导的名词性从句中充当主语、宾语、表语或者定语，而且引导名词性从句的what在任何情况下都不能省略。例如：
That he will succeed is obvious. 显然，他会成功。(引导主语从句的that不在其中充当具体的句子成分)
What she told me is not true. 她所告诉我
的都不是真的。(what在其引导的主语从句中作宾语)
3. whether与if均可以引导表示“是否”之意的名词性从句，且whether与if均不在这种名词性从句中充当具体的句子成分。在引导宾语从句时whether与if一般可以互换，但在引导主语从句、表语从句、同位语从句、介词后的宾语从句、放于句首的宾语从句或者名词性从句中包含or (not) 时通常只能用whether作引导词。注意体会下列例句：
I don't know if/whether I can help you. 我
不知道我能否帮助你。(宾语从句)
// Whether we can really help you, I don't know yet. 我们是否真的能帮助你，我还不知
道。(位于句首的宾语从句)
// The teacher worried about whether he had hurt the girl's feelings. 老师为是否伤害了那女孩的感情而担心。(介词后的宾语从句) // The question is whether they can cooperate with us. 问题是他们能否与我们合作。(表语从句)
// The question whether he should come himself or send a substitute must be decided upon. 他该亲自来还是派人替他来，这个问题必须定下来。(同位语从句)
// The little girl asked her father whether she should go to the party or not. 那女孩问她的父亲她应不应该参加这个晚会。(包含or not的宾语从句)
注意：肯定形式的doubt后面通常接whether/if引导的宾语从句，否定形式的doubt 后面通常接that引导的宾语从句，
例如：I doubt whether it's true. 我怀疑它是否是真实的。
// I doubt if that was what he wanted. 我怀疑那是否是他所想要的。
// I don't doubt that you are honest. 我不怀疑你的诚实。
// She never doubted for a moment that she was right. 她对自己是正确的这一点从不怀疑。
［考题1］— Could you do me a favor?
— It depends on ____ it is. (2006北京)
A. which
B. whichever
C. what
D. whatever
［答案］ C
［解析］下划线处的引导词引导on后的宾语从句，并且在该宾语从句中充当表语，表示疑问句“What is it? (你要我帮的忙是什么？)”的含义。注意：题干中没有用“whatever” 进行强调的必要。
［考题2］— I think it's going to be a big problem.
— Yes, it could be.
— I wonder ____ we can do about it. (2002北京春)
A. if
B. how
C. what
D. that
［答案］ C
［解析］下划线处的引导词引导wonder 后的宾语从句并且在该宾语从句中充当do的宾
语，if，that引导名词性从句时都不充当名词性从句中的句子成分，how引导名词性从句时充当名词性从句中的方式状语，因此应排除A、B、D而选出C。本题中what we can do about it 可以理解为对应于疑问句“W hat can we do about it?”的名词性从句，what引导的这种名词性从句跟其他疑问词形式的引导词所引导的名
词性从句的含义相近。
［考题3］You can only be sure of ____ you have at present: you cannot be sure of something ____ you might get in the future. (2007安徽)
A. that; what
B. what; 不填
C. which; that
D. 不填; that
［答案］ B
［解析］第一个下划线处应填入一个可以引导of的宾语从句泛指“你现在所拥有的东西”且在该宾语从句内部充当have的宾语的词，这样的引导词只能是what，由此可以直接排除选项A、C、D而选出B。
［考题4］____ we can't get seems better than ____ we have. (1996)
A. What; what
B. What; that
C. That; that
D. That; what
［答案］ A
［解析］名词性从句what we can't get和what we have中what都充当宾语，都属于关系代词型的what，本身不表示疑问而表示泛指相关的事物；“what we can't get”相当于包含定语从句的“things that we can't get”，“what we have”相当于包含定语从句的“things that we have”。
［考题5］It is generally considered unwise to give a child ____ he or she wants. (1997)
A. however
B. whatever
C. whichever
D. whenever
［答案］ B
［解析］whatever在这里的用法跟关系代词型的what一样，其引导的名词性从句“whatever he or she wants”泛指一个孩子想要
的任何东西。
［考题6］It was a matter of ____ would take the position. (1998上海)
A. who
B. whoever
C. whom
D. whomever
［答案］ A
［解析］下划线处的引导词所引导的名词性从句充当介词of的宾语，在其引导的宾语从句内部充当的是主语(通常用who指代)而不是宾语(通常用whom指代)，而且题干中没有提供强调“任何人”的语境，因此应填入引导词who。
［考题7］Could I speak to ____ is in charge of International Sales, please? (2007山东)
A. anyone
B. someone
C. whoever
D. no matter who
［答案］ C

［考题8］Mary wrote an article on ____ the team had failed to win the game. (2005)
A. why
B. what
C. who
D. that
［答案］ A
［解析］下划线处引导的名词性从句属于介词on的宾语，在该名词性从句中引导词充当原因状语，所以应选A。
［考题9］Please remind me ____ he said he was going. I may be in time to see him off. (2006)
A. where
B. when
C. how
D. what
［答案］ B
［解析］题干中所有句子都围绕时间展开，因此应填入表示时间的when引导remind的直接宾语。
［考题10］Information has been put forward ____ more middle school graduates will be admitted into universities. (上海2000)
A. while
B. that
C. when
D. as
［答案］ B
［解析］陈述客观情况的名词性从句的引导词之后是完整的陈述句，引导词本身不充当该名词性从句中具体的句子成分，有这样用法的引导词只能是that。本题下划线处引导了information的同位语从句(为避免头重脚轻，本句中information的同位语从句与information
之间被谓语动词部分隔开)。
［考题11］The other day, my brother drove his car down the street at ____ I thought was a dangerous speed. (2004上海春)
A. as
B. which
C. what
D. that
［答案］ C
［解析］下划线处的引导词引导介词at的宾语从句，该引导词在at的宾语从句中所包含的又一个宾语从句(充当think的宾语)里充当主语，特指说话人的兄弟驾车的速度，四个选项中只有关系代词型的引导词what具有这样的用法。注意：本题中at的宾语从句中又包含一个宾语从句，总共出现了两个宾语从句，其中第二个宾语从句(I thought之后的宾语从句)的引导词that被省略了。
［考题12］Elephants have their own way to tell the shape of an object and ____ it is rough or smooth. (2005天津)
A. 不填
B. whether
C. how
D. what
［答案］ B

［考题13］____ team wins on Saturday will go through to the national championships. (2006山东)
A. No matter what
B. No matter which
C. Whatever
D. Whichever
［答案］ D
［解析］下划线处引导全句的主语，因此不能选用只能引导让步状语从句的选项A、B；下划线处表示“任何一支(获胜的球队)”之意，用which的相关形式更为合适，因此进一步排除C 而选出D。
主语从句的基本用法:
在句中作主语的名词性从句称为主语从句，主语从句所对应的谓语动词通常用第三人称单数
的形式。为了整个句子的平衡，主语从句经常后置，并用it充当形式主语(此时，that引导的主语从句若不放在句首，可以省略引导词that)。
例如：What she did is not yet known. 她干了什么尚不清楚。
// Whoever comes is welcome. 不论谁来都欢迎。// It is a pity (that) we haven't contacted for ages. 很遗憾，我们几年没联系了。
// It has not been decided where the meeting is to be held. 在哪里开会还没决定。
// It doesn't matter whether she will come or not.
她是否来这无关紧要。
注意：不要混淆it 作形式主语指代主语从句与it引导强调句型的情况：
it作形式主语代替主语从句主要是为了平衡句子结构，主语从句的连接词没有变化；it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that(被强调部分指人时也可用who/whom)
区分it 作形式主语指代主语从句与it引导强调句型的有效技巧是：将“It be ... that ...”中的it be和that去掉后，句子仍然成立的是强调句，句子不能成立的是that引导的主语从句。
例如：It was my suggestion that made him confident of success. 正是我的建议使他对成功有了自信。去掉it be和that后可以构成完整的强调句型的原型“My suggestion made him confident of success.”，因此本句属于强调句。It is my suggestion that he needs more practice. 他需要更多的练习是我的建议。去掉it be和that 后本句讲不通，因此本句属于主语从句。

A. What
B. Who
C. Whatever
D. Whoever
［答案］ A
［解析］题干中的主语从句特指“使得这家商店与众不同的事物”，而且没有强调“使得这家商店与众不同的任何事物”之意，应选用what引导主语从句。
［考题2］____ fashion differs from country to country may reflect the cultural differences from one aspect. (2002上海春)
A. What
B. That
C. This
D. Which
［答案］ B

A. If
B. Whether
C. That
D. Where
［答案］ B
［解析］下划线处的引导词之后接了一个完整的陈述句，但整个主语从句不是客观陈述某种情况而是要表示“是否”的意思，应选用引
导词whether。注意：表示“是否”的名词性从句的引导词if不能用于引导主语从句。
［考题4］It is pretty well understood ____ controls the flow of carbon dioxide in and out the atmosphere today. (2003上海)

D. for
［答案］ B
［解析］本题下划线处引导的是一个放在句末的主语从句(被句首的形式主语it所指代)。陈述客观情况的名词性从句的引导词之后是完整的陈述句，引导词本身不充当该名词性从句中具体的句子成分，有这样用法的引导词只能是that。
［考题6］It is none of year business ____
other people think about you. Believe yourself. (2007福建)
A. how
B. what
C. which
D. when
［答案］ B
［解析］下划线处引导主语从句表示“其他人如何想你”，在该主语从句中充当think的宾语，四个选项中只能选择what做引导词。题干中what引导的主语从句放在句末、由句首的形式主语it所指代。
表语从句的基本用法：
名词性从句在be等系动词后作表语时被称为表语从句，
例如：The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。(how 在表语从句中充当方式状语)
The scissors are not what I need. 这把剪刀不是我所需要的。(what 在表语从句中充当宾语) What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语，that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)
That is what I want to tell you.那就是我想要对你讲的。(what在表语从句中充当直接宾语) That is why she failed to pass the exam. 那就是她考试不及格的原因。(why 在表语从句中充当原因状语)
注意：“That is why...”是常用句型，意为“这就是……的原因/因此……”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结
例如：
That is why you see this old woman before you know, Jeanne. 珍妮，这就是现在这个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异，说话人对她讲述了其中的原因之后，用这一句来进行概括)。
That is why I came. 这就是我来的原因。
下面是两个与“That is why...”形式相似的结构，它们与“That is why...”结构之间的关系要能够辨析清楚：
(1)“That is why...”与“That is the reason why...”同义，只不过从语法结构上讲，“That is the reason why...”中why引导的是—个定语从
句，将其中的the reason去掉则与“That is why...”结构一样，例如：
That is (the reason) why I cannot agree. 这就是我不能同意的理由。
(2)“That is because...”句型中从属连词because引导的名词性从句在此作表语，这也是个常用句型，意为“这就是为什么……/因为……”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...”则指由于各种原因所造成的后果，例如：
He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影，那是因为他得帮助他的妹妹做作业。(第一句话说明结果，第二句话说明原因)
He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影，因此他昨天晚上没有去看。(第一句话说明原因，第二句话说明结果)

名词性从句考点纳 概念: 在整个句中起名词作用的从句,包括主语从句、宾语从句、表语从句和同位语从句。 判断： 主语从句在谓语动词前，且常用形式主语it 宾语从句在动词、介词、形容词后 表语从句在系动词后（be, seem, look等） 同位语从句在名词后且引导词在从句中不作成分 连接词分为三类： 从属连词：that, (不充当从句的任何成分, 不可省，没有意义 whether/ if (不充当从句的任何成分，不可省，“是否”的意思) 连接代词：what(ever), who(ever), whom(ever), which(ever),whose: 充当主、宾、表、定 连接副词：when, where, how, why (充当状语) 名词性从句的做法 1.判断 2.从句中缺什么给什么 考点一：what vs. that what 在句中充当成分，后面跟意思是： that在从句中充当成分，后面跟，意义 you have done might do harm to other people. you don’t like him is none of my business. 考点二：that 的省略 ●由连接词that引导从句时，that 在句中不担任任何成分，在口语或非正式 的文体中常被省去，但是，从句是并列句时，第二个分句及以后的分句前的that 。 He told me (that) he will go to Shanghai tomorrow and he will visit many sights. ●that位于句首引导主语从句时，不能省略。 He will win the match is certain. It is certain that he will win the match. he will win the match is certain.
专题14 名词性从句——精讲深剖 一．单句语法填空 1.（2019全国卷I）While they are rare north of 88°,there is evidence they range all the way across the Arctic,and as far south as James Bay in Canada. 【答案】that 【解析】考查同位语从句。根据句子结构分析可知，主句为there be句型，且结构完整，空格后为同位语从句，解释说明中心词evidence的内容，故填that。 2. （2018全国卷III）I'm not sure 61 is more frightened，me or the female gorilla (大猩猩) that suddenly appears out of nowhere. 【答案】who 【解析】考查宾语从句。句意：我不确定谁受到了更大的惊吓，是我还是那只不知从何处突然出现的雌性大猩猩。根据句意和句子结构可知，空处引导宾语从句，在从句中作主语，表示“谁”，故填who。 二．单项选择 1.（2019江苏卷）Scientists have obtained more evidence ___________ plastic is finding its way into the human body. A. what B. that C. which D. where 【答案】B 【解析】考查同位语从句。句意：科学家已经获得更多证据，塑料正在进入人们的体内。从句不缺句子成分，且与evidence指代的是同一事件，用that引导同位语从句。故选B。 2.（2018江苏卷）By boat is the only way to get here, which is _______ we arrived.

名词性从句精讲 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。That he will come h ere surprises me. I know that he will come here. The news is that he will come here.The new that he will come here surprises me. 一、名词性从句的相同点：1.结构 2.连接词 引导名词性从句的连接词可分为三类： 从属连接：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 二、四大名词性从句的剖析 1.主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that 在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： That he suddenly fell ill last week made us surprised. 上星期他突然生病了让我们很惊讶。 Whether he will be able to come remains a question.他是否能够来仍然是一个问题。What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。Where the English evening will be held has not yet been announced.英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1）It + be +形容词+主语从句It is very interesting that he likes such kind of books. （2）It + be +名词+主语从句It is a pity that he missed the lecture. （3）It + be +动词的过去分词+ that从句It is said that they have won the game. （4）It +不及物动词+ that从句It seems that something is wrong with the computer. 另注意在主语从句中用来表示必须、理应如此、建议、要求等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is suggested (requested, proposed, desired, etc.) that… 2.宾语从句 名词性从句用作宾语叫宾语从句，在句中可以作谓语动词或介词的宾语。引导宾语从句的连接词与
名词性从句考点及易错点归纳总结 考点：关系词的选用 原则：缺啥补啥，补缺用连接词或连接副词，具体选择看句意 易错点： 1.名词性从句关系词的省略问题：除了宾语从句可以省略that关系词外，其他的都不行。另需注意宾语从句如有两引导词that，则第一个可省，第二个不可。 2.主语从句及宾语从句常考的几个形式主语\宾语结构 （一）it作形式主语的常见句型： (1)It＋be＋形容词(necessary/likely/important/certain等)＋that从句 (2)It＋be＋名词(短语)(a pity/a shame/no wonder等)＋that从句 (3)It＋be＋过去分词(said/told/reported等)＋that从句 (4)It＋不及物动词(seem，appear，happen，matter等)＋that从句 （二）形式宾语 宾语一般放在及物动词或介词之后，但是，在下列情况下，须用it作形式宾语，而将真正的宾语(常为不定式/从句)后置。
(1)动词find/feel/think/consider/make＋it＋宾补(形容词或名词)＋不定式/从句 (2)动词hate/ like/ dislike/ appreciate/enjoy＋it＋从句 (3)短语动词see to/ depend on/rely on＋it＋从句 (4)固定搭配take it for granted that/owe it to sb.that＋从句 3.if 与whether 的异同 只用whether的情况： （1）主语从句位于句子开头 （2）介词后的宾语从句； （3）引导表语从句或同位语从句； （4）与or not连用； （6）与to do 连用 3. 语序问题：含有疑问意思的语序用陈述语序 4. 时态问题：与主句保持一致，但客观真理需用一般现在时。 5. 名词性从句的虚拟语气问题→that sb (should) do 6. 其他常考的表语从句 (1)This/ That/ It is why＋表语从句(表结果)“这/那就是……的原因” (2)This/ That/ It is because＋表语从句(表原因)“这/那是因为……” (3)The reason why...is that＋表语从句“……的原因是……” 7. 同位语从句与定语从句的区分 同位语从句在句中作某一名词的同位语，位于该名词之后，用以说明该名词的具体内容。定语从句则是对于从句中的某一名词进行修饰。 常见同位语从句的名词：advice，conclusion，doubt，fact，hope，idea，news，promise，question，suggestion，thought，truth，wish，word等。引导同位语从句的引导词：that，whether，how，where，when，why等。 The manager put forward a suggestion that we should have an assistant.There is too much work
【英语】名词性从句考点解析（Word版附答案）（word） 一、名词性从句 1．We believe ________ you have been devoted to ________ naturally of great necessity. A. that; being B. all that; be C. that all; are D. what; is 【答案】 D 【解析】【分析】句意：我们相信你所投入的当然是非常必要的。分析句子可知，believe 后接宾语从句，宾语从句中you have been devoted to缺少宾语，表示事物故用what；what you have been devoted to为主语，从句作主语，谓语动词用单数，故选D。 【点评】考查名词性从句和主谓一致，本题涉及what引导的主语从句和一般现在时。 2．Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。 【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。 3． is even more important is the earth cooled down, water began to appear on its surface. A. When; that; when B. What; whether; as C. What; that; as D. lt; whether; as 【答案】 C 【解析】【分析】这题考查从句的用法，第一空填what引导主语从句，在主语从句中what做主语，第二空填that引导表语从句，在表语从句中，as是引导时间状语从句，句意是：甚至更重要的是：随着地球的冷却，水开始出现在表面。选C。 4．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question. A. focused; whether B. focused; if C. has focused; whether D. has focused; if 【答案】 C 【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。
2021年高考英语语法核心考点复习：名词性从句知识点 概述：名词性从句的功能相当于名词。根据其在句中充当的成分，可分为：主语从句、宾语从句、表语从句和同位语从句。 主语从句 在复合句中做主语的从句叫主语从句。引导主语从句的连词：that（无意义，所引导的主语从句是完整的），whether （是否），if （是否）（通常只能用于it作形式主语的主语从句），连结代词： who （谁）（主格）, whom （谁）（宾格）, whose（谁的）（所有格）, what （什么，所……的（东西或事情））, which （那个，那些），whoever （无论谁）（主格）, whomever （无论谁）（宾格）, whatever（无论什么）, whichever （无论那个，无论那些），连接副词： when（何时）, where （何地）, how （怎样，如何）, why （为什么）等。如： That the 2022 Winter Olympic Games will be held in Chengde is known to us all. =It is known to us all that the 2022 Winter Olympic Games will be held in Chengde. =What is known to us all is that the 2022 Winter Olympic Games will be held in Chengde. =As is known to us all, the 2022 Winter Olympic Games will be held in Chengde.
名词性从句名词性从句引导词的基本用法：概念：（一）同宾语、名词性从句是指可以像名词一样在句子中充当主语、表语、了解各种引导词的使用首先要从整体上把握其基本形式，位语的从句。对于名词性从句， 同位语从句各自的一些特征。表语从句、宾语从句、方法。其次，要分别了解主语从句、（二）名词性从句的引导词 名词性从句的引导词引导词是否在名词性从句中充当成分的情况 连接代词：what, which, who, whom, whose 连接副词：when, where, why, how, what, which在从句中作主语、宾语、表语或定语； who在从句中作主语、表语；whom在从句中作宾语；whose在从句中作定语；when, where, why, how在从句中分别作时间状语、地点状语、原因状语、方式状语 连词: that;whether, if否 名词性从句的引导词： 1. 引导特殊疑问句的疑问词在转为引导名词性从句时，即成为连接代词(主要包括what, which, who, whom, whose)或者连接副词(主要包括when, where, why, how)。 注意体会如下例句：Choose which you like best. 选你最喜欢的。 // Who has taken away my bag is unknown. 谁拿走了我的包还不知道。 // Have you decided whom you are to nominate as your candidate? 你们是否已经决定提名谁做候选人了?/ / He asked when Mr. Gilbert would be allowed to go home. 他问什么时候可以允许吉尔伯特先生回家。 // Where we can look up his address is still a problem. 我们在哪儿可以查到他的地址还是个难题。// Why he did that wasn't quite clear. 他为什么做那件事还不十分清楚。 // How they will solve the serious problem has not been decided. 他们将怎样解决这个严重问题还没有决定。 以下两种特殊情况要给予特别关注： 也可以的问题，”？……什么“作连接代词引导的名词性从句既可以表示一个问what(1)． 表示相当于“名词/代词＋关系代词引导的定语从句”结构的意思，这种特殊用法在语法上被称作“关系代词型的what”，注意体会如下例句： He is not what (=the person that) he was a few years ago. 他不是几年前的他了。 // This is what (=the place that) they call Salt Lake City. 这就是他们称作盐湖城的地方。 // What (=the place that) is now the North Sahara Desert was once a civilized world. 现在的北部撒哈拉沙漠曾是一个文明世界。 // Our income is now double what (=the income that) it was ten years ago. 我们现在的收入是十年前的两倍。 // The color of the flower is different from what (=the color that) it was in the morning. 花朵(现在的)颜色与它早上的颜色不同。 (2) 带'ever后缀的疑问词除引导让步状语从句之外，还可以引导名词性从句(“no matter＋疑问词”的结构只能引导让步状语从句，不可以引导名词性从句)，注意体会以下例句：Whoever wants to see this film can go with us tonight.无论谁想看这部电影，今晚都可以和我们一起去。
（直击高考）2013高考英语语法重难点系列专题10 名词性从句考 点 在句子中起名词作用的句子叫名词性从句(Noun Clauses），引导名词性从句的词叫连词。名词性从句又分别称为: 主语从句、宾语从句、表语从句、同位语从句 主语从句：是在复合句中充当主语的从句，常放在谓语动词之前或者用形式主语it代替，将其本身放在句尾。 例如：1. That he came here just now has been proved. 他刚才来的这里得到了证实。 解析：That he came here just now在谓语has been proved的前面，所以是主语从句。 2. It’s true that we are going next week. 我们下星期走是真的。 解析：真正的主语是 that we are going next week，前面的it是形式主语。 宾语从句：在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）和介词之后。 例如：1. We all know what he is. 我们都知道他是干什么的。 解析：what he is作及物动词know的宾语从句。 2. His worry is about whether he can succeed. 他的担忧是关于他是否能成功。 解析：whether he can succeed作介词about的宾语从句。 表语从句：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+联系动词+表语从句 例如：1. His question is where he can buy a house. 他的问题是他能在哪里买房子。 解析：where he can buy a house是联系动词is后面的表语从句。 2. This is why we can’t get their support. 这就是我们得不到他们支持的原因。 解析:why we can’t get their support是联系动词is后面的表语从句。 同位语从句：是用以说明所修饰名词的具体内容的，它与被修饰的词语通常可以划等号。例如：We heard the news that our team had won. 我听说了我们球队获胜的消息。

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。
名词性从句知识点总结 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。名词性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、介词宾语等，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。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型） d) It is John that broke the window.是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that …事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) It is ＋形容词＋从句 It is natural that…很自然… It is strange that…奇怪的是… (3) It is ＋不及物动词＋从句 It seems that…似乎… It happened that…碰巧… It appears that…似乎… (4) It ＋过去分词＋从句 It is reported that…据报道… It has been proved that…已证实… It is said that…据说… 3. 主语从句不可位于句首的五种情况： （1）if 引导的主语从句不可居于复合句句首。 （2）It is said /reported…结构中的主语从句不可提前。例如： 正确表达：It is said that President Jiang will visit our school next week. 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn’t matter whether he is wrong or not.

名词性从句 名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。例如：
It is a pity that you didn't go to see the film. It doesn't interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that … 事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is ＋形容词＋从句 It is natural that… 很自然… It is strange that… 奇怪的是… (3) it is ＋不及物动词＋从句
