上海高三英语名词性从句讲解与练习

一．概念：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、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。

二、引导名词性从句的连接词

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

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…

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.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.It is a consolation that she is still alive.练习：

1._____ as much as one-fifth of all timber harvested is not used.A.The estimate

B.The estimated C.They are estimated

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：

She did not know what had happened.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.注意：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。如：

I admire their winning the match.I admire that they won the match.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.He impressed the manager that he was an honest man.7.否定的转移

若主句谓语动词为think, consider, suppose, 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。

练习：

1.I wonder _______.A.whether or not I’ll catch the last bus B.if or not I’ll catch the last bus

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：

6． ____ he said at the meeting astonished everybody present．（MET93）A．What B．That C．The fact D．The matter 二, 表语从句：

定义：一个从句在复合句中作主句的表语，这个从句就叫作表语从句。可以接表语从句的连系动词有 be, look, remain, seem 等。

1.The problem is that millions of people die of illnesses caused by smoking.2.The question remains whether we can win the people.3.That’s just what I want.4.This is where our problem lies.5.The difficulty is how I can help smokers kick their habit.值提注意的是：

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…

The reason why he was dismissed is that he didn’t work hard.It is because the tobacco companies want to remain in business.练习：

1.What the doctors really doubt is____ my mother will recover from the serious disease soon．

4.I had neither a raincoat nor an umbrella．____I got wet all through．（98上海）A．It's the reason B．That's why C．There's why D．It's how 三，同位语从句：

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）

第四篇：高中名词性从句讲解与练习1

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，因而从句中用陈述句语序。连接代词与连接副词在从句充当句子成分，（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.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.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

It is common knowledge that„ „„是常识

It is a surprise that„ 令人惊奇的是„„

It is a fact that„ 事实是„„

（2）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„„（3）It + be + 动词的过去分词 + that从句

It is believed that„ 人们相信„„

It is known to all that„ 众所周知„„

It has been decided that„ 已决定„„（4）It + 不及物动词 + that 从句 It appears that„ 似乎„„

It happens that„ 碰巧„„

It occurred to me that„ 我突然想起„„

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

（三）表语从句

1、表语从句在复合句中作表语，位于系动词之后。

e.g.The question was who could go there.2、引导表语从句的连接词that有时可省去。

e.g.My idea is(that)we can get more comrades to help in the work.（四）宾语从句

1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。

e.g.I hope(that)everything is all right.2、介词之后的宾语从句，不可用which或if连接，要分别用what或 whether。

e.g.I’m interested in whether you’ve finished the work..I’m interested in what you’ve said.3、whether与if都可以引导宾语从句，常可互换。但下面情况不能互换。

①宾语从句是否定句时，只用if，不用whether。

e.g.I wonder if it doesn’t rain.②用if 会引起误解，就要用whether。

e.g.Please let me know whether you want to go（此句如果把whether改成if，容易当成条件句）③宾语从句中的whether 与or not直接连用，就不能换成if；不直接连用，可换。e.g.I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.④介词后的宾语从句要用whether引导。whether 可与不定式连用。whether也可引导主语从句、表语从句、同位语从句，还可引导让步状语从句，以上均不能换成if。但引导条件从句时，只能用if，而不能用whether。

e.g.It depends on whether we have enough time.They don’t know whether to go there.Please come to see me if you have time.注意：在demand、order、suggest、decide、insist, desire, request, command, doubt等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。

例如：I insist that she(should)do her work alone.我坚持要她自己工作。

The commander ordered that troops(should)set off at once.司令员命令部队马上出发。

（五）同位语从句

同位语从句在句中作某一名词的同位语，用来说明名词的内容，这些名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。

例如：.I have no idea when he will be back.The fact that he had not said anything surprised everybody.同位语从句和定语从句的区别：

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
