【考情分析】

名词性从句是历年高考的重点和难点也是热点。名词性从句相当于名词,可用作主句的主语、表语、宾语和同位语。因此,名词性从句分为主语从句、表语从句、宾语从句和同位从句。引导名词性从句的连接词有: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;连接副词:when, where, why, how,有词义,在从句中担任成分,作状语;连接词:that, whether, if, as if,if (whether), as if虽有词义,但在从句中不担任成分;that 无词义,在从句中不担任成分,有时可省略。

今后对名词性从句的考查仍将集中在关联词的选用上,特别石堆what引导的名词性从句的考查。名词性从句与其他从句的混合考查将在今后高考中占据一席之地。易混句型的辨析,比如it作形式主语,主语从句后置的句型与强调句型的辨析将仍作为高考考查的重点。

【知识点归纳】

名词性从句的用法

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。

一、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:连词:that(无任何词意);whether, if(均表示“是否”表明从句内容的不确定性);as if ,as though(均表示“好像”,“似乎”)。

以上在从句中均不充当任何成分

连接代词:what, whatever, who, whoever, whom, whose, which. Whichever, whomever

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.

二、具体分类

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。

Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。

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。

【典例1】(2009·上海卷)It is immediately clear ____ the financial crisis will soon be over.

A. since

B. what

C. when

D. whether

【答案】D

【解析】考查主语从句的用法。该句的意思时:经济危机是否会很快结束是很明显的事情。“是否”用whether表示,不能选when是因为从句中由soon这一实践状语。

【典例2】(2008·山东卷)_____ was most important to her, she told me, was her family.

A. It

B. This

C. What

D. As

【答案】C

【解析】she told me是插入语,可删除。what引导主语从句,在从句中充当主语。

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…

【典例】(2009·天津卷)It is obvious to the students ______ they should get well prepared for their future.

A. as

B. which

C. whether

D. that

【答案】D

【解析】考查名词性从句。本空格处应是一个主语从句的引导词,因该主语从句不缺成分,且句意完整,故应用不作任何成分的连词that。

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不可省。例如:

He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。

We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好,别人什么都不好。

注意:在demand,order,suggest,decide,insist,desire,request,command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。

(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。例如:

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。

【典例1】(2008·北京卷)The companies are working together to create _______ they hope will be the best means of transport in the 21st century.

A. which

B. that

C. what

D. who

【答案】C

【解析】create后为宾语从句,从句中they hope是插入语,可删除。因为从句中缺少主语,所以用what引导该从句。

【典例2】(2009· 全国卷Ⅰ) Could I speak to is in charge of International Sales please?

A. who

B. what

C. whoever

D. whatever

【答案】C

【解析】考查名词性从句。题干中介词to后面为宾语从句,从句中缺少主语,因此填whoever。

(3)用whether或if引导的宾语从句,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;e. 后接动词不定式时。例如: 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。

The question is whether she should have a low opinion of the test?

Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。

I wonder whether he will come or not. 我想知道他来还是不来。

Can you tell me whether to go or to stay? 你能否告诉我是去

还是留?

(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。例如:

he studies English every day. (从句用一般现在时)

he studied English last term. (从句用一般过去时)

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

he has studied English since 1998. (从句用现在完成时)

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。例如: The teacher told us that Tom had left us for America.

(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。例如:

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。例如:

The fact is that we have lost the game. 事实是我们已经输了这场比赛。

That’s ju st what I want. 这正是我想要的。

This is where our problem lies. 这就是我们的问题所在。

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 .

【提拨】whether 可引导表语从句,但与之同义的if却通常不用于引导表语从句。

【典例1】(2009·山东卷)The little girl who got lost decided to remain ________she was and wait tor her mother.

A. where

B. what

C. how

D. who

【答案】A

【解析】remain是系动词,后加表语从句,由句意可知,从句缺地点状语,所以选A。

【典例2】(2008·天津卷)The last time we had grat fun was _______ we were visiting the Water Park.

A. where

B. how

C. when

D. why

【答案】C

【解析】was后为表语从句,此处when与the last time相呼应,根据句意可排除其他选项。

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。

The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。

【典例】(2009· 重庆卷) We should consider the students’

request ________ the school library provide more books on popular science.

A. that

B. when

C. which

D. where

【答案】A

【解析】考查名词性从句。根据题意知,空格处是同位语从句的引导词,修饰中心名词request,且在句子中不充当成分,故用that。这句话的意思是我们应该考虑学生的这个要求,即学校图书馆应该多提供一些大众科学方面的书籍。

三、对比与用法

1.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)

2.that-从句作主语通常用it作先行词,而将that-从句置于句末。

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……

b. It + be + -ed 分词+ that-从句

It is believed that… 人们相信……

It is known to all that… 从所周知……

It has been decided that… 已决定……

c. It + be +名词+ that-从句

It is common kn owledge that… ……是常识

It is a surprise that… 令人惊奇的是……

It is a fact that… 事实是……

d. It +不及物动词+ that-分句

It appears that… 似乎……

It happens that… 碰巧……

It occurred to me that… 我突然想起……

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。

3.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。

【备考策略】

考生对于名词性从句的复习和应试关键要把握每个引导词的意义,因为在对于名词性从句的考查中,引导词在句子中都起作用,有意义,因此在分析句子结构,对比辨别名词性从句、状语从句、强调句式后,最后还是要选择引导词;另外还要注意以下几点:

1.what 引导词的考查,尤其位于介词后引导的宾语从句以及引导名词性从句时的双重作用。

2.Whether和if 的区别,尤其注意他们的不同之处。

3.名词性从句和其它从句的`兼容结构测试。

4.句子语序和时态。

具体说:

1.掌握名词性从句的分类功能

名词性从句根据其在主句的功能作用又可分为主语从句、宾语从句、表语从句和同位语从句。

(1) 若从句在句中作主语为主语从句

(2) 若从句在句中作宾语为宾语从句

(3)若从句在句中作表语为表语从句

(4) 若从句在句中作同位语为同位语从句

2.掌握连词的含义及分类

绝大多数名词性从句的连词都有其实在意义,称为有义连词,如what表“……的内容”,when表“……的时间”,where表“……的地点”,why表“……的原因”,how表“如何;怎样”,who表“谁”,if, whether表“是否”;没有实在意义的连词叫无义连词,无义连词只有that一个。

3.掌握名词性从句的语序

名词性从句用陈述语序。

4.掌握名词性从句和其它从句之间的关系

有些连词除引导名词性从句外还可引导其它从句,应掌握它们之间的关系。

(1) if ,whether表"是否"时引导名词性从句;if表“如果”时引导条件状语从句;whether表“无论是否;不管是否”时引导让步状语从句。

(2) when表“……的时间”,where表“……的地方”时引导名词从句;when表“当……的时候”引导时间状语从句,where表“……的地方”,且修饰行为动词时,引导地点状语从句;when, where从句作定语修饰先行词时引导定语从句。

【专题突破】

高考中考查名词性从句时,经常考查连接词的选用。解题时应先

判断从句的类型,然后判断从句是否缺少成分以及意义是否完整,最后根据引导名词性从句的连词的特点确定特定的连接词。要求学生在做题中要注意如下几点:

1.分析结构,辨析名词性从句和状语从句;

2.理解句意,正确区别引导词;

3.按照句意,出现那个引导词意思,便选择那个引导词。

【参考答案及解析】

1. C 句意:我脑海中突然出现一个温情的念头,用我的零花钱给妈妈买些鲜花作为她的生日礼物。本题考察名词性从句用法。I might use the pocket money to buy some flowers for my mother’s birthday .做A warm thought 的同位语从句。中间被suddenly came to me隔开,增加了试题难度。此外,部分考生由于对同位语从句和定语从句不分,故错选D为答案。

2. D 表语从句中缺did的宾语。

3. A “_______is still a wasteland now .”做介词in的宾语从句,从句中缺主语句意为:政府已经宣布一座现代化的城市将在这片现在仍是废墟的地方建成。

4. A“_______Liu Xiang had failed to compete in the event.”做介词on的宾语,宾语从句中不缺主干,故排除B和C。另外that 不引导介词的宾语从句(固定搭配除外),所以排除D。

5. B “_______is described as one of the most beautiful islands .”宾语从句,从句中缺少主语,

6. B whoever在宾语从句中做主语,部分学生,因为只看到介词to,误认为要添whomever做介词的宾语。

7. B “_______it takes to keep a nation highly competitive.”做表语从句,从句中缺少takes的宾语,构成 it takes sth to do sth 结构。

8. A本题句子结构比较复杂,“_______ a nation loses in times of disaster will be made up for by her progress”做a truth的同位语从句,同位语从句中_______ a nation loses in times of disaster为主语从句。本句共有两个从句,故有两个引导词。句意为“中华民族的经验证明了一个真理,即,一个民族在灾难中失去的,必将从民族的进步中得到补偿。

9. C “_______has recently been done to p rovide more buses for the people”在句中做让步状语,而D. Though what错误, 因为, 一个单一的从句不能用两个连词引导.句意: 尽管在为人们提供更多公交车这件事上, 投入了很多, 但是公交工具的缺乏, 仍然是个问题.

10.B “_______is certain”在句中做主语,主语从句缺少一个主语,需要用What; “_______prevention is more important than treatment .”系表语从句,句意与结构完整,只有that,可以这样用。

11.A“_______ they lost the game.”在句子中做the fact 的同位语从句,从句意思结构完整,结构完整。

12. C先将句子结构理清楚,it is _______that has made him _______he is today 就可以判断,第一个空是考察强调句型的特殊疑问形式;第二个空则是表语从句,表语从句中缺少he is的表语。句意:病人好多了,是什么使得他成为现在这个样子。

13. A考生误以为是地点状语从句,误选C.where。而reached是及物动词,后边接的是宾语从句,宾语从句除去插入语they thought,应该缺主语。

14.B 考察同位语从句,表达A plan的具体内容,has been put

forward将名词与从句隔开,加大了难度。

15.C 主要测试主语从句。分析句子结构可知:句子属于形式主语格式;另外主句中缺少主语。双重作用的引导词只能是what。例如:It is still doubtful what he said at the meeting yesterday。昨天他在会上说的话仍然值得怀疑。

16.C 名词性从句的引导词。句意为:她对我们来说是非常宝贵,我们已经准备好做一切来拯救她的生命。

17.D 此处从句作介词to的宾语,是名词性从句,引导词作从句的主语,指人,意思是:无论是谁,选D。

18.C 考查名词性从句,介词from后除了接代词或名词作宾语外,还可接介词短语或副词短语作宾语;由后面“I was born”可以推测from后面可以指时间,也可以指地点,再由所给的选项可得出答案。

19.D 考查名词性从句。宾语从句中缺少主语,因此选what。

20. B考查同位语从句。此处是由what引导的同位语从句,表示“你有没有可能来机场接我?”。所以选B项。

英语中的名词性从句

10、名词性从句:起名词作用的句子叫做名词性从句,其中包括:(主语从句、宾语从句、表语从句、同位语从句) (1)、主语从句:作主语的一个句子叫做主语从句。主语从句通常由一些词来引导。 A、不担当任何成分的连接词:that/which. 例子:○1That you have passed the exam will make your friendship (主语) (谓语)(宾语)surprised.

=The thing that makes me disappointed is that you lied to me. 使我感到失望的是你向我撒谎。 C、作状语成分连接副词:When、Where、Why、How (1)、When连接主语从句,在其所引导的从句充当时间状语。 例子: When the meeting will be begun is doubtful. (主语)(系动词)(表语)这会议什么时候开始还被受疑问中。 (2)、Where连接主语从句,在其引导的从句中充当地点状语。 例子:Where his pen is lost is unknown.

英语名词性从句课件 英语名词性从句课件 【考情分析】 名词性从句是历年高考的重点和难点也是热点。名词性从句相当于名词,可用作主句的主语、表语、宾语和同位语。因此,名词性从句分为主语从句、表语从句、宾语从句和同位从句。引导名词性从句的连接词有: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;连接副词:when, where, why, how,有词义,在从句中担任成分,作状语;连接词:that, whether, if, as if,if (whether), as if虽有词义,但在从句中不担任成分;that 无词义,在从句中不担任成分,有时可省略。 今后对名词性从句的考查仍将集中在关联词的选用上,特别石堆what引导的名词性从句的考查。名词性从句与其他从句的混合考查将在今后高考中占据一席之地。易混句型的辨析,比如it作形式主语,主语从句后置的句型与强调句型的辨析将仍作为高考考查的重点。 【知识点归纳】 名词性从句的用法 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。 一、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:连词:that(无任何词意);whether, if(均表示“是否”表明从句内容的不确定性);as if ,as though(均表示“好像”,“似乎”)。 以上在从句中均不充当任何成分 连接代词:what, whatever, who, whoever, whom, whose, which. Whichever, whomever 连接副词:when, where, how, why

英语名词性从句(详细讲解)

名词性从句 第一部分:语法讲解 名词从句是指在句子中起名词作用的各种从句。根据它们在句子中所起的作用不同,名词从句可以分为主语从句、表语从句、宾语从句和同位语从句。 如:That the earth is round is a fact. I don’t know if he needs my help. I don’t know where he went. 2.主语从句 1)主语从句在句中作主语。 如:Whether he will accept the invitation is not clear.他是否会接受邀请还不清楚。 When he left is unknown.他什么时候离开还不知道。 That he will come to the discussion is certain.他来参加讨论是肯定无疑的。 2)主语从句放在句首,句子常常显得比较笨重,因此常把它移至句子末尾,而用it作形式上的主语。 如:It is strange that she did not come yesterday. 很奇怪,她昨天没有来。 It has not been announced when the plane is to take off.飞机何时起飞还没有宣布。 It is a pity that Mr.Brown can’t attend our English meeting.真可惜,布朗先生不能出席我们的英语晚会。 3)有些用“it”作形式主语的主语从句结构已形成固定的用法。 a)It is +名词+从句 如:It is a fact that…事实是…… It is common knowledge that………是常识 b)It is +形容词+that从句 如:It is necessary that…有必要…… It is likely that…有可能…… It is important that…重要的是…… c)It is +过去分词+从句 如:It is said that…据说…… It is reported that …据报道…… It is well known that…众所周知……

America's new plan to buy up toxic assets will not work(这一部分为主句)。 unless从句1前的连接词。banks mark assets to levels 从句1。表示条件的从句。如果... which从句2前的连接词。buyers find attractive 从句2。修饰前面levels的定语从句。 (一)名词性从句(当成名词来用的句子) 包括:1、宾语从句(最重要);2、表语从句(最不重要);3、主语从句(一般重要); 4、同位语从句(一般重要)。 4种从句的写法一样,不一样的是位置不一样。 先看:1、宾语从句(最重要) 1)含义:是一个作宾语的句子,位置是把它放到主句里作主句的宾语。 例句:The fossil record shows that many species have endured for millions of years. 全句是一个主句,但是that many species have endured for millions of years作了该主句的宾语。即that many species have endured for millions of years为宾语从句。 2)宾语从句的写法:先写两简单句,其中一个简单句作主句时省略掉宾语,然后将另一个简单句接到作主句的宾语位置当宾语即可,但是要注意连接词的使用。 那么连接词该如何用呢? a、陈述句变宾语从句 例如:Dr . Worm acknowledges ...... These figures are conservative.(将这个陈述句放到上面这个句子里当宾语,如何放呢?)

英语中的名词性从句

英语中的名词性从句 名词性从句是英语语法中的一个重要部分,它在句子中充当名词的角色。在英语中,名词性从句可以作为主语、宾语、表语或同位语,起到连接句子的作用。本文将探讨名词性从句的不同类型以及其在句子中的应用。 一、名词性从句的类型 名词性从句分为主语从句、宾语从句、表语从句和同位语从句。这些从句的不同类型决定了它们在句子中的不同作用。 1. 主语从句 主语从句作为句子的主语,引导整个句子的核心内容。例如: "What she said is true."(她说的是真的。) 在这个例子中,主语从句"What she said"作为整个句子的主语,起到引导句子核心内容的作用。 2. 宾语从句 宾语从句作为句子的宾语,接受动词的作用。例如: "I don't know where she went."(我不知道她去哪儿了。) 在这个例子中,宾语从句"where she went"作为不及物动词"know"的宾语,接受动词的作用。 3. 表语从句 表语从句作为句子的表语,用来描述主语或宾语的性质或状态。例如: "The important thing is that you try your best."(重要的是你要尽力而为。)

在这个例子中,表语从句"that you try your best"用来描述主语"the important thing"的性质。 4. 同位语从句 同位语从句用来解释或说明名词的含义。例如: "His belief that hard work pays off is inspiring."(他坚信努力工作会有回报,这令人鼓舞。) 在这个例子中,同位语从句"that hard work pays off"用来解释名词"belief"的含义。 二、名词性从句的引导词 名词性从句的引导词包括连词"that"和连接代词"who"、"whom"、"which"、"what"、"whose"、"where"、"when"、"why"等。这些引导词在句子中起到引导名词性从句的作用。 1. 连词"that" 连词"that"在名词性从句中常用于主语从句、宾语从句和表语从句。例如: "I believe that he is innocent."(我相信他是无辜的。) 在这个例子中,连词"that"引导宾语从句"he is innocent"。 2. 连接代词 连接代词"who"、"whom"、"which"、"what"、"whose"、"where"、"when"、"why"在名词性从句中起到引导作用,并在从句中充当特定的名词角色。例如:"Whoever arrives first will get a prize."(谁先到谁得奖。) 在这个例子中,连接代词"whoever"引导主语从句,并在从句中作为主语。

英语名词性从句专题

英语名词性从句专题 一、考点、难点回顾 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

高考英语名词性从句

专题十名词性从句 第一节基本知识与基本概念 【什么是名词性从句?】 【主语从句】 顾名思义,主语从句在句子中作主语。有时本身出现在主语的位置上,也有时出于句子结构的考虑退到句子的尾部,前面用形式主语it代替。从句作主语时,谓语动词一般为单数形式。如: What I saw was beyond any verbal description. That his hair was turning grey worried him a bit. Why the company denied the contract is still unknown. When and where the government will build a city square is under discussion. It is pretty annoying that a small part of the machine is missing. It remains to be seen whether the new novel will be well received. 【宾语从句】 在句子中作宾语的从句就是宾语从句。由于这是同学们接触比较早的一种从句,应该问题不大。所以在近年的高考题中,以宾语从句的知识作为考点的题目较少。但是,宾语从句也有自己的特殊情况,如介词的宾语,形容词的宾语,宾语从句提前和并列的宾语从句等现象。如: We assumed that there would be more than 100 guests. He told the police in detail what he saw and heard. Nobody is sure what humans will look like in a million years. That will depend on whether they can get the chance. Whether I will have the time I am not sure at the moment. The conductor complained that we were not gifted in singing and that he would never come again. 【表语从句】 表语从句的最重要脸谱就是它们应该出现在系动词的后面。如: The only question left is how often the workers are paid.

名词性从句 在句子中起名词作用的句子叫名词性从句。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。 概说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 以及由how 构成的词组如how many ,how much, how soon, how often ,how far ,how long, how tall ,how high等. 1,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。例如: 主语:That he is still alive is sheer(全然的) luck.他还活着全靠运气。 动词宾语:John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。 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。 介词宾语: I know nothing about him except that he is from the United States. 除了知道他是从美国来之外,我对他全无了解 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 upsets everyone in his office. 近来谁也没有见过他,这一情况令办公室所有的人不安。 2 if, whether引导的名词性从句 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that-从 句的功能相同。例如: 主语:Whether the plan is doable 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。 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。 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 looking into the question whether the man is trustworthy. 他们调查他是否值得信赖。 2)选择性疑问从句 选择性疑问从句由关联词if/whether…or或whether…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。
