第一篇：中考英语名词性从句讲解含练习(迟)

名词性从句 主语从句

主语从句的语序

主语从句要求使用陈述句语序，而非一般疑问句语序。如：

What surprised me most was that the little girl could play the violin so well.How he was successful is still a puzzle.连接词的选用

（1）that和what的选用

that和what都可引导主语从句。what除起连接作用外，还在名词性从句中充当某些成分，可作从句的主语、宾语或表语。而that在名词性从句中不充当任何成分，无词义，只起连接词作用。如： What he wants is a book.他想要的是一本书。

That light travels in straight lines is known to all.众所周知，光线沿直线运行。（2）if和whether的选用

引导主语从句，不能用if，只能用whether。如：

Whether we will hold a party in the open air tomorrow depends on the weather.我们明天是否在户外开晚会要看天气而定。（3）其它连接代词和副词的选用

根据主语从句的具体意义，正确的选择who, which, when, where, why, how等连接词，这些连接词既有疑问含义，又起连接作用，同时在从句中充当各种成分。如：

When we shall hold our sports meet is not decided.我们何时举行运动会还没有决定。Who broke the glass yesterday is not clear.还不清楚昨天谁打破了玻璃。

Which car you will choose to buy makes no difference.你决定买哪一辆车都不会有任何区别。（4）whatever / whoever的功用

whatever, whoever在主语从句中不含疑问意义。它引导主语从句，并在从句中作主语、宾语、表语等。whatever = anything that;whoever = anyone who。要注意和whatever, whoever引导的让步状语从句的区别。如： Whoever breaks the law should be punished.（主语从句）（＝Anyone who breaks the law should be punished.）Whoever breaks the law, he should be punished.（让步状语从句）（＝No matter who breaks the law, he should be punished.）

it构成的主语从句（1）由连词that引导的主语从句，在大多数情况下会放到句子的后面，而用代词it作形式主语。谓语是seem, appear, be certain, be a pity, be a wonder, be one's hope, be likely等词或短语时。

It is well-known that the earth moves around the sun.众所周知，地球围绕太阳转。

需要注意的是，it作形式主语代替主语从句时，要注意和as引导的定语从句的区别。试比较： It was reported that the US was under the terrorist attack.（主语从句，有that，无逗号）

As was reported, the US was under the terrorist attack.（定语从句，无that，有逗号）上两句意为“据报道，美国遭到恐怖分子的袭击”。

用于It is suggested / required / ordered / demanded that...句型中,动词为表示命令、建议、要求等意义的词。主语从句应使用虚拟语气,谓语动词用“should + 动词原形”,should可以省略。例如:

It is suggested that you(should)spend more time in studying English.你应该花更多的时间学习英语。（2）常见用it作形式主语的复合句结构

1.It is a fact（a good idea / a pity / a shame / no wonder / good news…）that…如： It's a pity that you missed the film.你没有看那部电影真是太遗憾了。

2.It is necessary（clear / true / strange/ important /wonderful / possible / likely…）that…

需要注意的是，这类主语从句中，谓语动词很多为“（should）＋动词原形”，即要用虚拟语气。如： It is necessary that you（should）master the computer.你很有必要掌握电脑。It is important that a student learn English well.学生学好英语很重要。It's clear that they badly need help.很明显，他们急需援助。

It is likely that a hurricane will arrive soon.飓风很可能马上就要到达了。

3.It is reported（well-known / hoped / thought / expected /said /believed/decided /suggested /ordered…）that…如： It is said that he was killed in the earthquake.据说他在地震中丧生了。

4.It seems（happened / appears / doesn't matter / makes no difference / …）that …如： It seems that they will win the game.看起来他们好像会赢得这场比赛。

It makes no difference whether he will attend the meeting or not.他是否会参加会议都无关紧要。The Foreign Minister said, “________ our hope that the two sides will work towards peace.” A.This is B.There is C.That is D.It is

句式

用形式主语it引导的主语从句相当多，有些已形成固定的语法和译法。常见的有： It is said that...据说…… It is reported that...据报导……

It is well known that...众所周知…… It is announced that...据宣布…… It is believed that...人们相信…… It is thought that...人们认为……

It is understood that...自不待言…… It must be pointed out that...必须指出…… It must be admitted that...必须承认……

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。

He was not ready to believe something just because Aristotle said so.(否定because状语)他并不因亚里斯多德说过如何如何，就轻信此事。

She had not been married many weeks when that man's younger brother saw her and was struck by her beauty.(否定状语many weeks)她结婚还不到几个月，这个人的弟弟就看见她了，并对她的美貌着了迷。

1.________ you don't like him is none of my business.A.What B.Who C.That D.Whether

2.After Yang Liwei succeeded in circling the earth, ________ our astronauts desire to do is walk in space.A.where

B.what C.that D.how

3.________ leaves the room last ought to turn off the lights.A.Anyone B.The person C.Whoever D.Who 表语从句

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＋连系动词＋表语从句”。可以接表 语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如：

1)The question is whether we can make good preparation in such a short time.2)This is why we can't get the support of the people.3)But the fact remains that we are behind the other classes.4)The reason he is late for school is that he missed the early bus.同位语从句

同位语从句就是在复合句中作名词的同位语的名词性从句。1.同位语从句的功能

同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：

1)The king's decision that the prisoner would be set free surprised all the people.2)The order that all the soldiers should stay still is given by the general.2.同位语在句子中的位置

同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如： He got the news from Mary that the sports meeting was put off.3.同位语从句与定语从句的区别

(1)定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。

(2)定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：

1)The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语）

2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）

第二篇：名词性从句讲解

名词性从句讲解

在复合句中起名词作用的从句叫做名词性从句。它包括主语从句、宾语从句、表语从句和同位语从句。历届高考试题名词性从句考查的焦点主要有以下5个方面 1.考查名词性从句的语序问题

2.考查引导词that与what的区别

3.考查it在名词性从句中作形式主语或形式宾语的用法

4.考查whether与if的区别

5.考查名词性从句的虚拟语气问题 语法要点剖析

一、名词性从句

主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。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 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： What he wants to tell us is not clear.他要跟我们说什么，还不清楚。It is known to us how he became a writer.我们都知道他是如何成为一名作家的。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 + 名词 + that从句

（2）It + be + 形容词 + that从句（3）It + be + 动词的过去分词 + that从句

（4）It + 不及物动词 + that从句 It is a pity(a shame, no wonder, etc.)that„

It is necessary(important, natural, strange, etc.)that „ It is said(reported, believed, known, etc.)that„ It does not matter(seems,appears etc)„ 2.宾语从句

名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。1.由连接词that引导的宾语从句

由连接词that引导宾语从句时，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，但如从句是并列句时,第二个分句前的that不可略，且并列句之间由and连接。He has told me(that)he will go to Shanghai tomorrow.他已经告诉我他明天要去上海。He found(that)he lost himself in the forest and that he had no way to dicide the right directions.他发现自己在树林里迷路了，而他又无法确定正确的方向。

注意：在demand、order、suggest、insist, desire,等表示要求、命令、建议、等意义的动词后，宾语从句常用“（should）+ 动词原形”。

I insist that she(should)do her work alone.我坚持要她自己工作。2.用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。I want to know what he has told you.我想知道他告诉了你什么。

She always thinks of how she can work well.她总是在想怎样能把工作做好。

She will give whoever needs help a warm support.凡需要帮助的人，她都会给予热情的支持。3.用whether或if引导的宾语从句实为一般疑问句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：

a.引导主语从句并在句首时；b.引导表语从句时；

c.引导从句作介词宾语时；

d.从句后有“or not”时；

Whether there is life on the moon is an interesting question.月球上有没有生命是个有趣的问题。Everything depends on whether we have enough money.一切要看我们是否有足够的钱。

4.注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用 不同时态。

I know(that)he will study English next year.（从句用一般将来时）

当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。

The teacher told us that Tom had left us for America． Our teacher told us that the earth runs around the sun

5.think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。We don’t think you are here.我们认为你不在这。I don’t believe he will do so.我相信他不会这样做。3.表语从句

在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。

The fact is that we have lost the game.事实是我们已经输了这场比赛。That is why he didn’t come to the meeting.那就是他为什么不到会的原因。It looks as if it is going to rain.看上去天要下雨了。

需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如： The reason why he was late was that he missed the train by one minute this morning 4.同位语从句

同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如： The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。I have no idea when he will come back home.我不知道他什么时候回来。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。

试比较下面两个例句:

I had no idea that you were here．（that引导同位语从句，不能省略）

Have you got the idea（that）this book gives you of life ？（that引导定语从句，作宾语，可以省略）

第三篇：名词性从句讲解

名词性从句与高考试题

名词性从句的界定与分类：

名词性从句相当于名词，可分别作主句中的主语、表语、宾语和同位语。因此，名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。从属连词that, if, whether;

连接代词who, whoever, whom, whomever, which, whichever, what, whatever, whose;连接副词where, when, why, how。

其中, 从属连词只起连接作用, 在从句中不充当任何句法成分，而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分.名词性从句均不能用逗号和主句分开。

一、主语从句：

定义：一个从句在复合句中作主句的主语，这个从句就叫主语从句。

二、主语从句的表现形式： １.由从属连词引导的主语从句：

a.Whether the country should build a nuclear power station is something we must discuss.b.That light travels in straight line is known to all.２.由连接代词引导的主语从句： a.What we need is more time.b.Whichever book you choose doesn’t matter to me.c.Whoever comes will be welcome.３.由连接副词引导的主语从句：

a.When the plane is to take off hasn’t been announced ． b.Where he has been is still a puzzle.c.How much water is flowing can be measured easily.三、关于形式主语 it

主语从句放在句首往往显得头重脚轻，不太平衡，因此，在大多数情况下都是在主语的位置上用一个形式主语 it，而把主语从句移到句未去。

关于形式主语 it: 以 it 作形式主语，把主语从句后置的常用句型有：（1）It + be + 形容词 + that/wh-从句

It is quite clear that Tom was fond of music.（2）It + be + 名词 + that/wh-从句

It is a pity that she has made such a foolish mistake.可应用于此句型的名词还有fact / shame / honor / question等。（3）It + be + 过去分词 + that/wh-从句

It’s not yet decided that when the test will be given.（4）It seems, happens 等不及物动词 + that/wh-从句 It happened that I didn’t take any money with me.但以下情况往往必须用it作形式主语，主语从句一般不能放在句首。a.It doesn’t matter whether he likes or not.b.It’s said that the highway will be open to traffic next year.c.Is it likely that it will snow in the afternoon? 练习：

1.表语从句的表现形式除了用从属连词，连接代词和连接副词引导以外，还可以由as, as if ,as though引导.Things were not as they seemed.It looks as if it is going to rain.2、另外还要注意以下常用的两种结构：

The reason why…is that …(而不用 because。)It(this, that)is because…

定义：在复合句中，用作同位语的从句称为同位语从句。

同位语从句一般由 that, whether 等连词引导，常放在 advice, doubt, fact, hope, idea, information, message, news, order, possibility, problem, question, reason, truth, word, suggestion.等名词的后面，说明该名词的具体内容。

l.The news that he had landed on the moon spread all over the world.2.I have no idea when he will be back.3.The thought came to him that Mary had probably fallen ill.4.He must answer the question whether he agrees to it or not.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。

试比较下面两个例句:

I had no idea that you were here．（that引导同位语从句，不能省略）

Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）

She will give whoever needs help a warm support.I wonder why she refused my invitation.2．介词后的宾语从句：

You can't imagine ____ when they received these nice Christmas presents．（94上海）A．how they were excited B．how excited they were C．how excited were they D．they were how excited

2.动词 doubt 用在疑问句或否定句时，其后宾语从句常用 that 作连接词；用在肯定句时，连接词用 whether 或 if 皆可，而不用 that。

Do you doubt that he will win ? I don't doubt that your proposition is wrong.He doubt whether I know it.3.否定转移问题。在主句为第一人称主语后跟 think , believe , suppose , expect , guess , imagine 等动词时，宾语从句的否定形式应转移到主句中。We don't expect he will come tonight , will he ? 4.主谓一致问题。

What he wanted to see was an end to all the armies of the world． What I bought were three English books． 5.语气问题

a.在含有 suggest , order , demand , propose , command , request , insist, desire, require, advise 等表示要求、命令、建议、决定等意义的动词后，that从句常用“（should）+ 动词原形”的结构

I suggest we(should)set off at once.b.在It is ＋过去分词＋that的主语从句中 decided，demanded，desired，insisted，ordered，proposed，suggested，recommended，requested，required等。It is desired that we（should）get everything ready this evening． c.在表语从句或同位语从句中。

The suggestion that the mayor(should)present the prizes was accepted by everyone．

d.在It is（was）＋形容词＋that从句中要用虚拟语气，即（should ＋）动词原形，表示建议或不满、惊奇等情绪。常用于此类的形容词有 essential，important，natural，necessary，possible，strange，等。It is necessary that a college student ________ at least a foreign language．（上海1993）

A．masters B．should master C．mastered D．will master 6．What引导名词从句的特殊含义:

What was once regarded as impossible has now become a reality．

(what为“所……的事”，相当于“the thing that．．．；all that．．．；everything that．．．”)After ________ seemed a very long time，I opened my eye and found myself in bed．

A．what B．when C．that D．which

He is not what he was a few years ago． Who is it that has made Fred what he is now？ What is now the North Sahara Desert was once a civilized world． Our income is now double what it was ten years ago

D.What;that 1.选D。what made matters worse 是主语从句(注意其后有谓语动词was)，相当于 the thing that made matters worse。

2.选A。what 引导的是表语从句，相当于 the thing that it takes to do anything well。3.选C。that 引导的是一个主语从句，句首的it为形式主语。

4.选 C。答句为省略句，其完整形式为 I was trying to prove to the police where I was last

night，在此 where 引导的是一个宾语从句。类似地，下面选 C：

“_______ made her struggle to become an artist so hard?” “______ she was a woman.” A.What, What

B.That, That C.What, That

D.That, What 5.选D。what 引导的是表语从句，what 在此相当于 the things that。

6.选 C。句首的 it 是形式主语，空格处所填词用于引导主语从句。由于该主语从句中又缺主语，故排除A、B、D。（注意：不能选 A，因为 that 引导名词性从句时不能充当句子成分）7.选 A。第一空填 what，是因为该主语从句中的动词 understand 缺宾语；why 和 because 均可引导表语从句，其区别是： why 引导表语从句强调结果，because 引导表语从句强调原因。句中空格后文表明的是结果，故用 why。

8.B。what 在此引导主语从句且在从句作宾语，它相当于 the thing that。

9.B。两空均填 what，均用于引导宾语从句，因为两个宾语从句中的动词 said 和do 均缺宾语，而在各个选项中只有 what 可用作宾语。

10.选 A。what 引导宾语从句。由于动词 wants 缺宾语，所以填 what。句意是：当你找工作面试回答问题时，请记住这条黄金定律：永远给予对方确实想要的东西。

11.选 A。I can to save them 为 I can do to save them 之略，此句中的 do 缺宾语，故选 whatever。

12.选 B。that 在此引导主语从句，无词义，也不充当句子成分。注意不要根据中文意思选 D，因为 because 不用于引导主语从句。13.选 C。两个空格处均为引导宾语从句的引导词，而四个选项中两者可引导宾语从句的只有 C。

14.选 B。比较 That’s why„ 与 That’s because„：前者用于强调结果，后者用于强调原因。如下面一题选 D：

I got wet all through._______ I had neither a raincoat nor an umbrella.A.It’s the reason

B.That’s why C.There’s why

D.That’s because

15.选 D。由 is worth praising 这一谓语可知前面是主语从句，排除不能引导从句的 B 项和 C 项；whoever 引导主语从句表示“任何„„的人”，在此它相当于 anyone who。16.选 A。how 引导主语从句，that 引导同位语从句。

2.B 通过对句子的分析可知，believe it or not是插入语，在此句中that引导的是the story的同位语从句。

3.D 通过对句子的分析可知，此题需要选一词来引导表语从句，而从句中的明显缺少宾语，故只能what用来充当。4.C 介词on后面宾语从句不完整，同时从句缺少主语，故只能由what来充当。

5.C wonder后面的从句是疑问句应用陈述语序。即：特殊疑问词+主语+谓语动词。6.B 此句主句完整，从句也完整，故用that引导构成与the fact的同位语从句。7.A why在它引导的从句中充当原因状语，从句在主句里充当介词on的宾语。

8.B what在它引导的从句中充当主语，同时整个从句可看成是idea的同位语从句，来说明idea的具体内容。9.B 本题考查定语从句以及固定短语turn to 的用法，关系代词因为在后面定语从句中做宾语因此省略掉，turn to sb 求助于某人。

10.B 本题根据意思以及后面与or 的搭配关系可判断该处是“是否”，whether 引导宾语从句。

11.B 本题考查名词性从句中的同位语从句，根据下文可知Danny留下的口信的内容，that 引导名词性从句。

12.C 本题考查双重疑问句，疑问词＋do you think/believe/expect＋句子的其他成分（句子用称述句语序）。13.C 本题考查固定短语 be different from同时也考查名词性从句中的宾语从句，介词from后是宾语从句，但从句中be used to 后面少宾语，且根据上文是我们过去习惯的方法，这用what 符合语意。

14.A 本题考查的是名词性从句中的表语从句，后面表语从句不完整，it was 后面还缺少表语，根据意思是“20年前的 样子”，后面一个句子是对20年前的补充说明，是一个非限制性定语从句，20年前学校设备条件不好，when 在定语从句中作时间状语。

15.B 本题考查名词性从句的同位语，doubt 后的同位语根据意思没有怀疑故选择that 引导，that在从句中不充当成分。

强化题

1.C whether引导的从句构成与名词the question的同位语。(原答案似乎有误)2.C 主句完整,同时从句也不缺成分。根据句意可看出that引导的从句构成与a warm thought的同位语。3.A that引导同位语从句，具体说明chance（可能性）的内容。4.B 句意：请提醒我他说他将什么时候走。

5.B 因先行词是natives，故淘汰A和D。又因give sth.to sb.固定短语，所以选B。介词to可放在关系代词whom的前面。w.w.w.k.s.5.u.c.o.m 6.B pleased后面缺少宾语从句，he was a man of action句意完整，故用that引导。

7.D No matter what/which只能引导让步状语从句，排除A和B。C和D的区别在于一个无范围，一个有范围。8.D wonder后面的宾语从句本是what makes him so excited：。但what需要被强调，故用强调句型。9.D 本题考查it 作形式主语, 后面的that 引导真正的主句从句.10.B 本题考查同位语从句, reason 后面有for 引导的短语, 接着后面是that 引导的句子来说明理由的内容.11.C 本题考查名词性从句的宾语从句,介词for 后接宾语从句但宾语从句中缺少主语, he thought 是插入语.连词what 引导宾语从句且在从句中充当主语,which 的意思不符合.12.C 本题考查固定短语 be different from同时也考查名词性从句中的宾语从句，介词from后是宾语从句，但从句中it had been 后面少表语，所以what 符合语意。

13.B 本题考查名词性从句中的介词宾语从句, 根据下文意思以及在宾语从句中作主语, D 不能引导名词性从句, who 表达的意思不对.14.C 本题考查名词性从句介词宾语, 宾语从句中you think 是插入语, 故句中缺少主语,which 意思不对,故选wh at

15.C 本题考查介词宾语从句, 根据上下文意思 该处应该是”我们是否能得到Green先生的
