高中考点语法系统：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

It seems that„ 似乎„ It happened that„ 碰巧„(4)it ＋过去分词＋从句

It is reported that„ 据报道„ It has been proved that„ 已证实„ 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：

It is said that President Jingo will visit our school next week.(right)That President Jiang will visit our school next week is said.(wrong)(3)It happens„, It occurs„ 结构中的主语从句不可提前。例如： It occurred to him that he failed in the examination.(right)That he failed in the examination occurred to him.(wrong)(4)It doesn’t matter how/whether „结构中的主语从句不可提前。例如：

It doesn’t matter whether he is wrong or not.(right)Whether he is wrong or not doesn’t matter.(wrong)(5)含主语从句的复合句是疑问句时，主语从句不可提前。例如： Is it likely that it will rain in the evening?(right)Is that will rain in the evening likely?(wrong)4.What 与that 在引导主语从句时的区别

What 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：

1)What you said yesterday is right.2)That she is still alive is a consolation.二．宾语从句

宾语从句就是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）或介词之后。

1.作动词的宾语

(1)由that引导的宾语从句（that 通常可以省略）,例如： I heard that be joined the army.(2)由what, whether(if)引导的宾语从句，例如： 1)She did not know what had happened.2)I wonder whether you can change this note for me.(3)动词＋间接宾语＋宾语从句。例如：

She told me that she would accept my invitation.2.作介词的宾语

例如：Our success depends upon how well we can cooperate with one another.3.作形容词的宾语

例如：I am afraid(that)I’ve made a mistake.That 引导的从句常跟在下列形容词后作宾语：

Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。

4.It 可以作为形式宾语 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。例如：

We heard it that she would get married next month..5.后边不能直接跟that 从句的动词

这类动词有Allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。例如：

I admire their winning the match.(right)I admire that they won the match.(wrong)6.不可用that从句作直接宾语的动词

有些动词不可用于“动词＋间接宾语＋that从句“结构中，常见的有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如： He impressed the manager as an honest man.(right)He impressed the manager that he was an honest man.(wrong)7.否定的转移

若主句谓语动词为Think, consider, wuppose, believe, expect, fancy, 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。例如：

I don’t think this dress fits you well.（我认为这件衣服不适合你穿。）

三．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.四．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。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：The king’s decision that the prisoner would be set free surprised all the people.宾语从句表语从句精练： Catherine said that she ___ to Guangzhou.A.has never gone B.had never gone C.has never been D.had never been 2 Linda said the moon___ round the earth.A.travelled B.has travelled C.travells D.had travelled 3I don't know ___ they have passed the exam.A.what B.if C.when D.where 4 I hardly understand.___ he has told me.A.that B.what C.which D.who 5.She didn't know___ back soon.A.whether he would be B.if would he be C.he will be D.if he will come 6.I want to know how long

第二篇：名词性从句

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：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）。二.名词性从句的分类如下

（一）主语从句

主语从句的句型.引导词有疑问词wh-及whether/if及that.1、主语从句在复合句作主语。疑问词引导e.g.Who will go is not important.2、用it作形式主语，主语从句放在句末。

3、If/whether 引导e.g.It doesn’t matter so much whether you will come or not.4．It+be+adj(obvious,true,natural,surprising,good,wonderful,funny,likely,certain,probable,etc)/名词词组（no wonder,an honor , a good thing,a pity,etc)+that从句 e.g.It’s certain that she will do well in the exam/It’s no surprise that our team has won the game.5．It+be+过去分词（said,reported,thought,expected,decided,announced,etc)+that从句

e.g.It’s said that Mr.Green has arrived in Beijing.Note:that引导主语从句时，在口语和非正式文体中可以省略，但that从句置于开头时不能省略。e.g.That he suddenly fell ill last week made us surprised.（二）表语从句

表语从句的句型及要点。引导词疑问词wh-及whether及that.1、表语从句在复合句中作表语，位于系动词之后。疑问词引导的： e.g.The question was who could go there.Note: 引导表语从句的连接词that一般不可省去。

e.g.My idea is that we can get more comrades to help in the work.连接词that一般不能省略，但当主句中含动词do的某种形式时，that可以省略。如： What I want to do is(that)I can go up to him and thank him.我想做的事是走到身边去感谢他

（三）宾语从句

宾语从句在复合句中作宾语。引导词有疑问词wh-及whether、if(if 和whether 有区别）及that.引导宾语从句的连词that一般可省略。e.g.I hope(that)everything is all right.Note:以下情况that不可省略：(不考查）

1.当宾语从句的主语是that时。2.2.当宾语从句中含有主从复合句时 Father promised that I studied harder he would take me to Beijing.3.当两个或多个宾语从句由并列连词连接时，除第一个从句中的that可以省略外，其余从句中的that都不可以省略。

4当that偶尔作except和in的宾语时。This book is unsatisfactory in that it lacks a good index.中，that it lacks a good index就是介词 in 的宾语从句，这当中的that就不能省略。

（四）同位语从句。引导词wh-及whether及that.同位语从句引导词有疑问词wh-及whether及that.同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。e.g.I have no idea when he will be back.The fact that he had not said anything surprised everybody.名词性从句易混知识归纳

易混点一 ：同位语从句与定语从句的区别

that引导的从句，是定语从句还是同位语从句，我们我们采用“试加 法”，来判断。The fact that he had not said anything surprised everybody.This is the fact that you must know clearly.1.when、where、why引导的从句

引导定语从句时，其意义与先行词有关，与先行词的意义基本相同，没有疑问意义；但引导同位语从句时，其意义完全与疑问词相同，即when表示什么时候，where表示哪儿，引导两种从句时，都在从句中做状语。如： I still remember the day when I first came to Beijing.句中的when相当于“on the day”它没有疑问词“什么时候”的意义，因此是定语从句。

I have no idea when she will be back.when与idea毫无意义上的关联，其意思是“什么时候”,因而是同位语从句。易混点二：reason后面的名词性从句

reason做主语时，后面的表语从句表示原因是要用that引导，一般不用because或why，而用it，this或that做主语时，后面的表语从句可用because或why引导。

1.“The reason +连系动词+that“引导的表语从句。本句型的意思是：理由是：。。。The reason was that he fell ill.2.It（或This、That）+连系动词+the reason+why引导的定语从句。本句型意为：这就是。。。的原因（理由）That is the reason why he failed in the contest, 3.It（或This、That）+连系动词+the reason+because引导的表语从句。本句型意为：这是因为。。。；这是由于。。。的缘故。That was because he fell ill.4.It（或This、That）+连系动词+why引导的表语从句。本句型意为：这就是。。。的原因。

That was why he fell ill.易混点三：what、whatever、who、whoever等引导的名词性从句 我们可以通过与定语从句的转化知道两组在意义上的差别。Whatever=anything that（无论什么）Whoever=anyone who（无论谁）

Whenever=any time=no matter when（无论何时）Wherever=any place=no matter where（无论何地）这都是泛指。而what、who、when、where则是特指。如： Who spoke at the meeting is unknown The person that spoke at the meeting is unknown.Whoever breaks the law will be punished.Anyone who breaks the law will be punished.注意：1.whatever、whoever、whenever、wherever等常引导主语从句、宾语或表语从句，也可以引导状语从句，等于“no matter +疑问词”。而no matter +疑问词只能引导让步状语从句。Eg：Whatever I said/No matter what I said, he wouldn’t listen to me..2whoever的宾格还是whoever，一般不用whomever。易混点 whether与if（不做考查）

二者都可以作“是否”讲，能引导名词性从句，都不能省略。1.在及物动词后引导宾语从句时可以互换；

注意：在某些动词后（如:discuss）只能接whether，不能跟if。如： We discussed whether we should close the shop.2.引导主语从句、表语从句、同位语从句时都用whether，不用if。如：

The question whether he should come himself or send another man hasn’t been decided.Whether he will win is all the same to me.The question is whether you can go there yourself.但如果主语从句是有It用作形式主语，if和whether都可以 It is unknown whetherif she is ill.3宾语从句中，如果whether后紧跟or not，不用换做if；若whether与or not分开使用，则可以换作if。如： I wonder whether or not he has arrived at the destination.I don’t know whetherif I can come or not.4.若宾语从句为否定结构，则多用if，而不用whether。如： I don’t care if he doesn’t show up.（炫耀）

5.在介词后引导宾语从句或与带to的动词不定式结合而构成不定式的复合结构时，只能用whether，而不用if。如：

I haven’t settled the question of whether I will go back home.She doesn’t know whether to get married now or wait.练习：名词性从句

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。

第五篇：名词性从句及习题

高中语法

名词性从句

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。 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

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,不充当成分，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.（what既保留自己的疑问含义，又起连接作用，并从句中充当成分）

It is known to us how he became a writer.（how既保留自己的疑问含义，又起连接作用，并从句中充当成分）

Where the English evening will be held has not yet been announced.（where既保留自己的疑问含义，又起连接作用，并从句中充当成分）

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

另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，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 a pity(a shame, no wonder, etc.)that„

It is suggested(requested, proposed, desired, etc.)that„

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。例如： The fact is that we have lost the game.That is why he didn’t come to the meeting.It looks as if it is going to rain.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 this morning

宾语从句

在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句.234567891011-
