名词性从句精讲
来源：普特英语
在复合句中起名词作用的从句叫名词性从句，包括作主语从句、表语从句、宾语从句和同位语从句。
(1)主语从句
就是在复合句中作主语的从句。主语从句常用that, whether, who, whom, whose, what, which, when, where, how, why, whatever, whoever等引导。如：
Whether he will be able to come remains a question. 他是否来还是问题。
That China is a great socialist country is well known. 众所周知，中国是一个伟大的社会主义国家。
注：为避免头重脚轻，使句子平衡，常用it作形式主语，而将主语从句后置。如上述第二
例常说成：
It is well known that China is a great socialist country.
但是，由连接代词what, whatever, whoever等引导的主语从句一般不能用形式主语。如：What he found surprised me greatly. 他的发现使我非常吃惊。
Whoever is finished may rest. 凡是做完工的人都可以休息。
(2)表语从句
就是在连系动词之后作表语的从句。引导表语从句的连接除与引导主语从句的连接词外，还有as if，as though。如：
The question is whether he is able to do it alone. 问题是他能否单独做这件事。
It looks as if (though) it is going to snow. 天好像要下雪似的。
注意：要区分以下句式：
1. that’s why+结果；that’s because+原因。
2. the reason why /for…is that…
He is absent. That’s because he is ill. 他缺席，这是因为他生病了。
He is ill. That’s why he is absent. 他病了，这就是他缺席的原因。
The reason why he is absent is that he is ill. 他缺席的原因是他生病了。
(3)宾语从句
就是在复合句中作宾语的从句。引导这宾语从句的连接词与引导主语从句的连接词基本相同。如：
They didn’t say which they wanted. 他们没有说他们想要哪一个。
I am sure (that) no harm will ever come to you. 我肯定你永远不会受伤害。
I was surprised at what has happened.我对发生的事感到惊讶。
注意：当think, believe, suppose等的疑问式后面跟连接代词或连接副词引导的宾语从句时，
习惯上将这些连接词置于句首，即“连接代/副词＋do you think /believe /expect＋宾语从句的
其余部分？”如：
Who do you think is the best player this year? 你认为今年谁是最佳运动员?
What do you suppose you will do after school? 你想放学后干什么？
(4)同位语从句
就是在句中作同位语的从句。它通常有放在thought, idea, news, word(=news), plan, doubt, question, fact, suggestion, belief等抽象名词的后面，说明这些词的具体内容或含义。同位语从句大多由that引导，也可由whether, how, when, where, why等引导，但不能由which引导。如：
The idea that the earth is round is not a new one. “地球是圆的”这种观点并不新鲜。
He must answer the question whether he agrees to it or not. 他必须回答他是否同意此事这们一问题。
I have no idea when he will set out. 我不知他什么时候出发。
注：有时，同位语从句并不紧跟在它所说明的词的后面。如：
The whole truth came out at last that he was a wolf in sheep’s clothing. 真相终于大白了，他原来是一只披羊皮的狼。
注意1 语序问题
不管什么词引导，从句的语序始终用陈述语序。如：
(1)He asked how he could find his courage. 他问道他如何才能找到他的勇气。
(2)The question is why there is little rain here. 问题是这里为什么雨水少。
注意2 连接词的选用问题
A．that，whether，if，as if(限用于表语从句)都不作句子的任何成分。
因此，它们所引导的句子结构必须完整。that 一般用于确定的语气中，引导宾语从句时，口语中的that可省略，而其他情况中的that一般不可省；而whether，if一般用于不确定的语句中。如：
(1)That he learnt English before is certain. 他学过英语是肯定的。
(2)I don’t know whether / if he will come. 我不知道他是否会来。
(3)He looks as if he knows the answer. 看起来他好像知道答案。
B．whether和if
1)whether可用于任何名词性从句中，而一般只能用于宾语从句中。如果if引导主语从句时，只能放在句中，而不能置于句首。如：
(1)Whether he will come or not doesn’t matter. —It doesn’t matter whether he will come or not. 他来还是不来都没关系。
(2)Do you know if / whether his words are true. 你知道他的话是否真实吗？
2)whether可与or not连用，而if则不可以。如
(1)I’m not sure whether / if he can overcome the difficulties. 我没有把握他能否克服这些困难。
(2)The radio didn’t say whether it would rain or not tomorrow. 收音机并没有报道明天是否下雨。
3)若用if会产生歧义时，则用whether。
(1)Let me know whether he will come. 告诉我他是否会来。
(2)Let me know if he will come. 可理解为：告诉我他是否会来。也可理解为：如果他愿意来，就告诉我一声。
4)whether可与不定式连用，而if不可以。
Have you decided whether to go there tomorrow? 明天是否去那儿，你决定了吗？(句子中的whether不能用if替换)
5)whether引导的从句可作某些介词及动词discuss的宾语，而if则不可以。如：
(1)They are talking about whether they will take part in the strike. 他们在谈论他们是否要参加这次罢工。
(2)They are discussing whether they can employ the new way. 他们在讨论他们是否可以采用这种新的方法。
(以上两个句子中的whether 不能用if替换)
6)宾语从句若为否定句，连接词则用if 而不用whether。如：
Do you know if he hasn’t been to Washington? 你知道他是否没有去过华盛顿吗？
此句子中的If不能用whether替换。
一、词序问题
名词性从句总是用陈述句词序，则不能使用疑问句词序，尤其是当名词性从句由“疑问词”引导时，不能受疑问句的影响而误用疑问句词序：
误：I didn’t know where did he live.
正：I didn’t know where he lived. 我不知道他住哪儿。
误：Who will he marry remains unknown.
正：Who he will marry remains unknown. 他同谁结婚还不知道。
二、时态问题
由于由when引导的时间状语从句和以if引导的条件状语从句要用现在时表示将来意义，而不能直接使用将来时态，所以许多同学容易受此影响在when和if引导名词性从句时也用现在时表示将来意义。请看几题：
(1) I don’t know if he ________ or not tomorrow.
A. come
B. comes
C. will come
D. is coming
此题答案选C，句中if引导的不是条件状语从句(if≠如果)，而是宾语从句(if＝是否)，句意为“我不知道明天他是否会来。”
(2) I don’t know if she ________, but if she ________ I will let you know.
A. comes, comes
B. will come, will come
C. comes, will come
D. will come, comes
答案选D，第一个if 引导的是宾语从句，第二个if 引导的是条件状语从句。
(3) “When he _____ is not known yet.”“But when he ____, he will be warmly welcomed.”
A. comes, comes
B. will come, will come
C. comes, will come
D. will come, comes
答案选D，第一个when 引导的是主语从句，第二个when引导的是时间状语从句。
另外，当主句为过去时态时，宾语从句通常要用过去的某种时态与之呼应(表客观真理时除外)：
The teacher told us that he knew everything. 老师告诉我们他知道一切。
The teacher told us that light travels faster than sound. 老师告诉我们光比声音传播得快。
一、什么叫同位语
当两个指同一人或事物的句子成分放在同等位置时，若其中一个句子成分是用于说明或解释另一个句子成分的，那么用于起说明或解释作用的句子成分就叫做另一成分的同位语。如：
Laura Myers, a BBC reporter, asked for an interview. 劳拉·迈尔，BBC的记者，要求采访。Influenza, a common disease, has no cure. 流行性感冒是一种常见病，无特效药。
Mary, one of the most intelligent girls I know, is planning to attend the university. 玛丽是我所认识的最聪敏的姑娘之一，她正准备上大学。
Who is that man, the first in the front row? 前排第一个人是谁?
We have two children, a boy and a girl. 我们有两个孩子，一个男孩和一个女孩。
以上所举的同位语例子都是同位语的基本形式，一般不会出错。但有有几种同位语，或由于身本结构特殊，或由于它修饰的成分结构比较特殊，往往会引起误解。现小结并举例说明如下，希望引起同学们的注意。
二、特殊同位语归纳
1. 代词we, us, you等后接同位语
Are you two reading? 你们二人在看书吗?
They three joined the school team. 他们3人参加了校队。
She has great concern for us students. 她对我们学生很关心。
He asked you boys to be quiet. 他要你们男孩子安静些。
We girls often go to the movies together. 我们女孩子经常一起去看电影。
2. 不定式用作同位语
Soon came the order to start the general attack. 很快下达了发起总攻的命令。(to start the general attack与the order同位)
He followed the instruction to walk along a certain street where I picked him up. 他照吩咐沿某一条街走，我在那里接他上了车。(to walk along…与the instruction同位)
3. -ing分词用作同位语
He’s getting a job tonight driving a truck. 他今晚得到一个开卡车的差事。(driving a track与a
job同位)
She got a place in a laundry ironing shirts. 她在一家洗衣店得到一个熨衣服的职位。(ironing shirts与a place同位)
The first plan, attacking at night, was turned down. 第一个计划是夜袭，被拒绝了。(attacking at night与the first plan同位)
4. 形容词用作同位语
The current affair, the biggest in its history, is being held in Guangzhou. 目前的交易会，是有史以来规模最大的，正在广州举行。
He read all kinds of books, ancient and modern, Chinese and foreign. 他读了很多书，古今中外都有。
People, old and young, took to the streets to watch the parade. 老老少少的人都来到街头观看游行。
【注】这类同位语与定语比较接近，可转换成定语从句。如：
The current affair, the biggest in its history, is being held in Guangzhou.
=The current affair, which is the biggest in its history, is being held in Guangzhou.
当名词后面所接的从句表示与名词同位并为名词的实际内容时，这个从句就是同位语从句。如：
The news that China has joined the WTO excite us all. 中国加入了世界贸易组织这一消息使我们大家兴奋不已。
He told us the truth that he fell down from his bike this afternoon. 他告诉了我们他从单车上摔下来这一真相。
同位语中应注意：
1. 高中所学能带同位语从句的名词不多，常见的有：answer, belief, conclusion, decision, discovery, doubt, explanation, fact, hope, idea, information, knowledge, law, message, news, opinion, order, possibility, problem, promise, proof, proposal, question, report, risk, rumor, story, suggestion, truth, theory, thought, wish, word等。如：
Hw sent us a message that he won’t come next week. 他送信来告诉我们说，下周他不来了。There is no doubt that he is fit for this job. 毫无疑问，它适合这一工作。
2. 表示“命令、建议、要求”advice, demand, decision, desire, idea, insistence, instruction, order, plan, proposal, recommendation, request, requirement, suggestion, wish 等名词的同位语，须用虚拟语气。如：
He made clear his desire that he should work hard to go to college. 他已清楚的表明了他要努力学习考上大学这一愿望。
Soon came the order that all the people should obey the rules. 不久命令下来了，所有的人不得违犯制度。
3. 同位语从句与定语从句的区别：
同位语从句与定语从句形相似而实质不同，具体表现在以下几个方面：
(1)被修饰的词不同。同位语从句的前面一般是数量有限的、表示抽象意义的名词；而定语
从句的先行词是无数的指人或物名词。
(2)从聚的作用不同。同位语从句表示同位名词的具体内容；而定语从句是对先行词—名词的限制、描绘或说明。
(3)引导词的作用不同。引导同位语从句的that是连词，在从句中不担任任何成分，但不能省略；而引导定语从句的that为关系代词，在从句中担任句子的某种成分，当担任定语从句中的宾语时，that可以省略。
(4)引导词不同。定语从句不能用what, how, whether引导；而同位从句可以用what, how, whether引导。
(5)判定定语从句和同位语从句的方法。同位语从句可充当同位名词的表语；而定语从句不能充当先行词的表语。
同位语从句的引导词：引导同位语从句的词语通常有连词that，whether，连接代词和连接副词等。
1. 由that引导
We heard the news that our team had won. 我们听到消息说我们队赢了。
They were worried over the fact that you were sick. 他们为你生病发愁。
The news that we are having a holiday tomorrow is not true. 明天放假的消息不实。

He referred to Copernicus’statement that the earth moves round the sun. 他提到了哥白尼关于地球绕太阳转的说法。
【注意1】在某些名词(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚
拟语气。如：
They were faced with the demand that this tax be abolished. 他们面对废除这个税的要求。They expressed the wish that she accept the award. 他们表示希望她接受这笔奖金。
There was a suggestion that Brown should be dropped from the team. 有一项建议是布朗应该离队。

The resolution that women be allowed to join the society was carried. 允许妇女参加这个协会的决议通过了。
I can understand their eagerness that you should be the main speaker. 我理解他们希望你作主要发言人的殷切心情。
【注意2】引导同位语从句的连词that通常不省略，但在非正式文体中也可以省去。如：
He gabbed his suitcase and gave the impression he was boarding the Tokyo plane. 他拿起了手提箱，给人的印象是他要登上飞往东京的飞机了。
2. 由whether引导
There is some doubt whether he will come. 他是否会来还不一定。
Answer my question whether you are coming. 你回答我的问题：你来不来。
The question whether it is right or wrong depends on the result. 这个是对还是错要看结果。We are not investigating the question whether he is trustworthy. 我们不是在调查他是否可以信任的问题。
【注意】whether 可引导同位语从句，但if不能引导同位语从句。
3. 由连接代词引导
Have you any idea what time it starts? 你知道什么时候开始吗?
From 1985-90 I was an instructor at the regional party headquarters. After that I went back to work in a factory. Then I had no idea what a casino was. 从1985年到1990年我是地方党部的教员。随后我回到一家工厂工作。当时我不知道赌场是什么样的地方。
4. 由连接副词引导

It is a question how he did it. 那是一个他如何做的问题。
He had no idea why she left. 他不知道她为什么离开。
You have no idea how worried I was! 你不知道我多着急!
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
高考英语一轮复习名词性从句精讲精练学案新人教版 名词性从句的几个难点 that通常不可省略的三种情况 (1)引导主语从句，that置于句首时。 That he failed in the exam made his parents disappointed. 他考试不及格让父母很失望。 (2)当一个句子有两个或多个并列的宾语从句时，引导第二和以后几个从句的that不可省略。 I wished (that) we could go sighting in Hangzhou this summer and that we could buy some books on our way back in Shanghai. 我希望今年夏天我们能去杭州旅游，并在返程时在上海买些书回来。 (3)由it作形式宾语时，that引导的宾语从句中，that也不可省略。 He has made it clear that he wouldn’t agree to the plan. 他已清楚表明不同意这项计划。 what和that在名词性从句中的区别 (1)what在名词性从句中可充当主语、宾语和表语，意义上相当于the thing(s) that，引导主语从句时，其谓语动词的单复数由表语的单复数而定；what引导的从句可作介词的宾语从句。 What he wants are those books.他需要的是那些书。 What he wants is some water.他需要的是一些水。 A modern city has been set up in what was a wasteland ten years ago.一个现代化的城市已经在10年前还是一块废地的地方建造起来了。 (2)that不充当任何句子成分，只起连接作用，无任何意义；引导主语从句时，常用it作形式主语，谓语动词用单数；引导宾语从句时，常被省略；that从句一般不充当介词宾语，偶尔可作except，in的宾语。 That she will refuse the offer seems unlikely. (＝It seems unlikely that she will refuse the offer.) 她不可能拒绝那个建议。 I have found (that) all the tickets have been sold out.
英语语法：名词性从句语法讲解 时间：2016-10-08作者：来源：精品学习网 笔者在此就名词性从句中的几大易错点进行分析，希望对同学们有所帮助。 [关系代词和关系副词的误用] 例1 （2016·全国卷Ⅰ） My uncle is the owner of a restaurant close to that I live. 解析 that→where。本题考查宾语从句，引导词在从句中充当地点状语，所以将that改为where。 例2 （2015·全国卷Ⅱ） As natural architects， the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days. 解析 how。根据语境和空后的形容词thick可知应用how引导宾语从句，此处表示要弄清楚到底土坯房的墙需要“多”厚。故答案为how。 点拨若从句缺少主语、宾语、表语或定语，则考虑用关系代词；若从句缺少时间、地点、原因、方式等状语成分，则使用关系副词 （when/where/why/how）。 [if和whether的误用] 例3 He asked her the question if they can be friends. 解析 if→whether。question后为同位语从句，只能用whether来引导，故而将if改为whether。 例4 It doesn’t matter so much you will come or not. 解析考查主语从句。句意：你来还是不来，这不怎么重要。代词it作形式主语，真正的主语是whether引导的主语从句。 点拨在表达“是否”这一意思时，我们经常会用到whether和if，但以下几种情况只用whether不用if： 1. 在表语从句、主语从句、同位语从句中； 2. 在介词后的宾语从句中。如：It all depends on whether they will
名词性从句精讲精析 ——主语从句、宾语从句、表语从句、同位语从句 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，其功能同名词一样。 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。(it is uncertain if he will leave for Beijing tomorrow. )
英语名词性从句练习全集及解析 一、初中英语名词性从句 1．________ manners are very important in every country is known to all，but the trouble is that different countries have different ideas about ________ good manners are. A. That; what B. That; that C. What; that D. What; what 【答案】 A 【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。逗号前有两个谓语动词，一个是are，一个是is known，故是两句话，需填连词连接这两句话，根据句意可知，前面是主语从句，故填that，此处的that，只起连接作用不作任何成分。about是介词，其后是个句子故应填连词把这两句话连接起来，所缺词作are的表语，故填what。因此选A。 【点评】考查名词性从句，本题涉及that引导的主语从句和what引导的宾语从句。 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．Has it been announced ______? A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。
高考必考语法精讲精练 语法专题十：名词性从句 名词性从句是比较重要的语法项目。《2017年普通高等学校招生全国统一考试大纲》附录语法项目表中对名词性从句列了四项：主语从句、宾语从句、表语从句和同位语从句。全国卷新课标Ⅰ对名词性从句的考查一般在语法填空和短文改错中，主要考查从句引导词的用法。 2015年高考全国卷Ⅰ没有考查名词性从句。 2016年高考全国卷Ⅰ第71题（短文改错）考查了宾语从句的引导词，My uncle is the owner of a restaurant close to that I live.本句中须将that改为where。 2017年高考全国卷Ⅰ没有考查了名词性从句。 在复合句中起名词作用的从句叫做名词性从句。名词可以充当句子的主语、宾语、表语和同位语，因此，名词性从句包括主语从句，宾语从句，表语从句和同位语从句。 ①What was most important to her was her family.(主语从句) ②I don’t know what you want to say.(宾语从句) ③The good news is that we have won the game.(表语从句) ④The news that we have won the game is true.(同位语从句) 注意：连词that在引导名词性从句时无词义，不充当句子成分，只起连接作用，在主语从句、表语从句和同位语从句中不能省略，在引导宾语从句时，口语或非正式的文体中常被省去；疑问代词、疑问副词、缩合连接词以及关联短语在句中既保留自己的含义又起连接作用，在从句中充当成分。名词性从句一般都用陈述句 ．．．的语序，即使从句表达的是疑问含义。例如： ①The problem is what he has done to the little boy. ②We all don’t know when he will come. 1. 主语从句 在复合句中作主语的句子叫主语从句 主语从句通常由从属连词that，whether 和连接代词what, who,which,whatever, whoever以及连接副词how,when,where, why等词引导。例如： ①That he stole a bike was true. ②What he wants to tell us is not clear. ③Who will win the match is still unknown. ④Where the English evening will be held has not yet been announced.
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.

【本讲教育信息】 一、教学内容 寒假专题：名词性从句精讲精练 名词往往在句中充当主语，宾语，表语和同位语。 在复合句中，代替名词充当主语，宾语，表语和同位语的句子统称为名词性从句。 名词性从句分为：主语从句、宾语从句、表语从句、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五类： a.连词：that（无任何词意，不作成分，只起连接作用，宾语从句中常可省略） 1) My hope is that she will soon be well again. (表语从句) 我的希望是她能很快康复。 2) Everybody hopes that she will soon be well again.（宾语从句） 大家都希望她能很快康复。 3) That she will soon be well again is our hope.（主语从句） 她能很快康复是我们的希望。 b. whether, if（均表示“是否”表明从句内容的不确定性，不作成分） 1) Whether he is coming or not doesn’t matter too much.(主语从句，不能用if) 2) I went in and asked if/whether they had a cheap suit. 3) I wonder whether/if he will come in such bad weather. c. 连接代词：what, whatever, which, whichever, (在从句中作主语，宾语，表语，指物) 1) ____he need is more time. 显然，主语从句：he是主语，谓语动词need缺宾语，因此应填what. 2) Tell us ___you saw and heard during your visit to that university. 3) This is not ___I want. 4) ____some people are against is ___other people are for. 5) The question is which team will win. 6) I have two apples, I don’t know which you want. 归纳：what一般用于不知道内容或范围的句子；which“哪一个……”一般用于给出内容或范围的句子。可作主语，宾语，表语，还可作定语。 d. who, whoever, whom, whomever, whose（在从句中作主语，宾语，表语，定语，指人） 1) Who will give us a lecture is unknown. 2) The question is who will come here. e. 连接副词：when, where, how, why, whenever, however, wherever (在从句中作状语) 1) I have no idea how he learned about it. 2) Where she has gone is not known yet. 3) When he will start is not known yet. 4) This is why he is late. 注意：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。

名词性从句精讲 来源：普特英语 在复合句中起名词作用的从句叫名词性从句，包括作主语从句、表语从句、宾语从句和同位语从句。 (1)主语从句 就是在复合句中作主语的从句。主语从句常用that, whether, who, whom, whose, what, which, when, where, how, why, whatever, whoever等引导。如： Whether he will be able to come remains a question. 他是否来还是问题。 That China is a great socialist country is well known. 众所周知，中国是一个伟大的社会主义国家。 注：为避免头重脚轻，使句子平衡，常用it作形式主语，而将主语从句后置。如上述第二 例常说成： It is well known that China is a great socialist country. 但是，由连接代词what, whatever, whoever等引导的主语从句一般不能用形式主语。如：What he found surprised me greatly. 他的发现使我非常吃惊。 Whoever is finished may rest. 凡是做完工的人都可以休息。 (2)表语从句 就是在连系动词之后作表语的从句。引导表语从句的连接除与引导主语从句的连接词外，还有as if，as though。如： The question is whether he is able to do it alone. 问题是他能否单独做这件事。 It looks as if (though) it is going to snow. 天好像要下雪似的。 注意：要区分以下句式： 1. that’s why+结果；that’s because+原因。 2. the reason why /for…is that… He is absent. That’s because he is ill. 他缺席，这是因为他生病了。 He is ill. That’s why he is absent. 他病了，这就是他缺席的原因。 The reason why he is absent is that he is ill. 他缺席的原因是他生病了。 (3)宾语从句 就是在复合句中作宾语的从句。引导这宾语从句的连接词与引导主语从句的连接词基本相同。如： They didn’t say which they wanted. 他们没有说他们想要哪一个。 I am sure (that) no harm will ever come to you. 我肯定你永远不会受伤害。 I was surprised at what has happened.我对发生的事感到惊讶。 注意：当think, believe, suppose等的疑问式后面跟连接代词或连接副词引导的宾语从句时， 习惯上将这些连接词置于句首，即“连接代/副词＋do you think /believe /expect＋宾语从句的
一对一个性化学科优化学案 一、概述 在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 It is a fact that English is being accepted as an international language. (主语从句) The trouble is that she has lost his address.（表语从句） They have no idea at all where he has gone.（同位语从句） Do you remember how he came?（宾语从句） 二、主语从句(subject clauses) 1、概述 在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、关系代词、连接副词等。引导主语从句的关联词有从属连词that 、whether ，关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever ；关系副词：when, where, how, why, however, whenever, wherever 等。 That you don’t like him is none of my business. What he said is true. Whether the football game will be played depends on the weather. 2、从属连词that ，whether 引导的主语从句。 从属连词that ，whether 在主语从句中的作用只是引导主语从句，它们在从句中不担任成分，不能省略。 Whether she will come or not is still a question. That they will go is certain. Whether she's coming or not doesn't matter too much. 3、it 作形式主语引导主语从句。 如果主语从句太长，为避免句子结构头重脚轻，我们可用it 作形式主语，而把主语从句放在主句谓语部分之后。That 引导的主语从句可用it 代替，that 不可省略。 用作it 作形式主语的结构： （1）It is/was +形容词+that 从句 It ’s natural that … 很自然…… It ’s obvious that … 显而易见…… （2）It is/was +名词+that 从句 It ’s a pity that … 遗憾的是…… It ’s a fact that …事实是…… 鹰击长空—基础不丢
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)
（英语）中考英语名词性从句解题技巧讲解及练习题(含答案) 一、初中英语名词性从句 1．________ his failure lies is expected ________ clear to us. A. What… to make B. How… made C. Where… to be made D. Why… making 【答案】C 【解析】【分析】句意：他的失败之处有可能被我们弄清楚。分析句子可知，主语从句中的lie为不及物动词，所以主句中缺少状语，因此填where。expect sth.to do.固定短语，“期望某事发生”，sth. be expected to do.意为”某事有可能发生“。make sth. clear to sb为固定搭配，意为“向某人阐明某事，使某人弄清某事”。本句中make的宾语是where his failure lies 是被弄清楚，要用动词不定式的被动形式。因此选C。 【点评】考查名词性从句及固定搭配，本题涉及主语从句和固定短语expect sth.to do. 2．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories. A. what that B. which C. that D. that what 【答案】 D 【解析】【分析】句意：有人指出，驱除焦虑所起着至关重要的作用是童年美好的回忆。本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。故选D。 【点评】考查名词性从句，本题涉及what引导的主语从句。 3． is clear to the members of the committee is that the President will not give in to their demands. A. Who B. It C. As D. What 【答案】 D 【解析】【分析】句意：委员会成员清楚的是，总统不会向他们的要求让步。that the President will not give in to their demands.这个句子作表语； is clear to the members of the committee这是主语从句，这里缺少主语从句的连接词，并且连接词在句中作主语，it是代词，不是了；连接词，故排除B；as作主语时，是在定语从句中，故排除C；who指人，根据表语指的事情，不是人，故排除A；what在主语从句中可以作主语或宾语，指事，符合句意，故选D。 【点评】考查名词性从句，本题涉及what引导的主语从句。 4．________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties. A. As; whose B. It; whose C. As; whom D. It; whom
名词性从句精讲精练 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）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. （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。
高中名词性从句语法详解 名词性从句：宾主同表（宾从，主从，同从，表从）一、宾语从句 宾语从句的类型 （1）主语+谓语+宾语从句 He said that he wouldn’t take part in the sports meeting. （2）主语+be+adj+宾语从句I’m sure that our team will win. ☆只限于少数adj. sure, certain, afraid, confident, etc （3）主语+谓语+宾（表）语+介词+宾语从句（except, in that在于，因为）He is a good student except that he is a little careless. I like the city,but I like the country better in that I have more friends there 1. 宾语从句的连接词 1）连词that,只起连接作用,在从句中不作句子成分,也无词汇意义,在口语中常被省略 ★由that 引导的宾语从句在以下情况下不能省略： (1).在主+谓+it(形式宾语)+宾补+that从句(真正宾语) 的句型中： 表喜欢、憎恶等心理活动的动词或词组后习惯上先跟形宾it：hate, love, enjoy, dislike, don’t mind, feel like, appreciate, rely/depend on, count on, see to, take, owe等 We must make it clear that we mean what we say. We heard it that she would get married next month. (2).由and连接的两个由that引导的宾语从句中,第二个that 不省略. He told me (that) he would come and that he would come on time. (3) 从句前有插入语： He may tell you, for example, that she is interested in Chinese (4）从句主语是that时：He says that that is a useful book (5)当that从句是双宾语中的直接宾语时，that不可省。 I can’t tell him that his mother died. 2）连词if、whether,它们起连接作用, 在从句中不作句子成分, 作“是否”解,在口语中多用if Tom doesn't know if / whether his grandpa liked the present. ★一般情况下，if和whether可以互换，但以下4种情况只能用whether: ①or not连用：I wonder whether he is coming or not. ②在介词后: It depends on whether it is going to rain. ③在不定式前: I haven’t decided whether to go there or not. ④如果用if会有歧义时：Please let me know if you want to go. 如果你想去/你是否想去 doubt引导的宾从，肯定句中用whether or if, 否定或疑问句用that I doubt that whether he can keep it up. I don’t doubt that he can keep it up. 3）连接代词who, whom, whose, what, which, 连接副词when, where, why, how:它们起连接作用,作句子成分，各有自己的意义 I wonder where he got so much money The teacher asked the new students which class he was in. 2. 宾语从句的语序（陈述语序） 1）连接词作主语，语序不变（主要注意以下连接词what / who / which / how many） I wonder how many students have finished their homework. I wonder what’s the matter / what’s wrong / what’s up / what happened / what is happening / who did it / which is the best 2）连接词不作主语，主语前不能出现“情/be/助动词” Could you tell me where she has gone? 3. 宾语从句的时态呼应 1）主现从随便（一般不用过去将来和过去完成) 2）主过从过(客观事实，时态不变)：主句是过去时，从句要变成相应的过去时态 4. 其他需要说明的问题 1）标点由主句决定,如主句是陈述句、祈使句,则用句号;是疑问句则用问号。
