名词性从句一，名词性从句的概念：1, 相当于名词，分为主语从句、表语从句、宾语从句和同位语从句2，名词性从句的引导词：that, whether, if (一般是宾语从句)，as if(表语从句)，who, whom, whose, what, which, when, where, why, how,以及由how组成的词组，如：how many, how long, how far两组需要注意的连接词that/what1）that和what都可以引导名词性从句，但that是连接词，本身无词义，仅起连接作用，不在从句中担任任何成份；what是连接代词，不仅引导名词性从句，而且在从句中充当一定的成份，如主语、宾语或表语。
e.g: That he stole a bike was true.The important thing is what you do, but not what you say.高考真题：_______ we can't get seems better than _______ we have.A. What; whatB. What; thatC. That; thatD. That; what2）whether和if均可引导动词后的宾语从句，常可互换。
a.在介词后面只能用whether，不能用if。

例如：①He doesn't know whether to stay or not.c.引导主语从句，表语从句，同位语从句时只能用whether。
例如：①It is unknown whether he will come. 他是否来还不知道。
②The question is whether they can take our advice.3.The question whether he'll come is unknown.3）doubt用于肯定结构时，后面用whether/ if引导名词性从句；用于否定结构或疑问结构时，后面用that引导名词性从句。

1It+系动词+形容词+that从句。

名词性从句 更新。 讲义
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。
名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。
分析历届高考试题名词性从句考查的焦点主要有以下六个方面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. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别6. 考查名词性从句的虚拟语气问题（一）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, why1. 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。
名词性从句讲义
名词性从句讲解1基础知识由一个主句和一个或一个以上的从句构成的句子叫复合句。
名词性从句相当于名词，可以作主语，宾语，表语和同位语。
因此，名词性从句可分为主语从句，宾语从句，表语从句和同位语从句。
如：I believe what he said.It remains to be seen whether this plan is practical enough to keep the project going.名词性从句的种类名词性从句的基本用法名词性从句就是用三种句子（陈述句、一般疑问句以及特殊疑问句）来分别充当另一个句子的四种不同句子成分（主语、宾语、表语和同位语）。
理解这一本质，是解决名词性从句的关键。
三种句子充当名词性从句时的结构变化：①陈述句作成分时，需要在句首加that; ②一般疑问句作成分时，需要将疑问句变成陈述语序，然后在句首加上whether或if，以保留原句的意义（if只用在宾语从句中）；③用特殊疑问句作成分时，只需将疑问句转换成陈述语序。
要学会分析疑问词的成分。
如：I have no idea when they will visit our school; we have got everything ready.What matters most in learning English is enough practice.Elephants have their own way to tell the shape of an object and whether it is rough or smooth.一、名词性从句的连词用法名词性从句的连接词有从属连接词、连接代词和连接副词。
考点一从属连接词1. that无词义，不做成分；that引导宾语从句时可省略，但引导的并列的宾语从句时，后一个that不可以省略。
That an earthquake happened in Sichuan shocked all the Chinese people.He said (that) he had been working here for ten years and that he wanted to go home.2. whether/ if “是否”，不作成分，不省略。
名词性从句讲义精简版
名词性从句定义：在句中承担名词的作用一、分类找出句子的谓语动词和分析句子的成分？思考名词可以做那些成分？阿甘正传The movie is so moving and encouraging.I appreciate his mother.Gump is a real man.I enjoy the part, the warm end.①What I saw repeatedly is so moving and encouraging.②I appreciate what his mother said.③Gump is who we should learn from.④I enjoy the part that a feather is flying in the sky.观察下面的句子，判断分别是什么从句？1. 主语从句：在主从复合句中作主语的从句，形式为：主从+谓语+其他(或者it 作形式主语)。
2. 宾语从句:在主从复合句中作宾语的从句，形式：及物动词+宾从，介词+宾从，形容词+宾从。
3. 表语从句:在主从复合句中作表语的从句，常跟在系动词之后，说明主语的状态、内容、特征和身份等。
形式为：主语+系动词+表语从句。
4. 同位语从句：在主从复合句中作名词的同位语的从句，常用在抽象名词后，解释说明抽象名词的内容。
二、识别（看左边原则）句首/it +主语从句动宾/介宾/形宾/ + 宾语从句系动词+表语从句抽象名词+同位语从句指出下列各名词性从句的种类1. I know whatever he did. (宾语从句)2. She wondered if the buses would still be running. (宾语从句)3. The truth is that the fog is too thick for the bus to run that far. (表从)4. She watched out for that she was being watched by a tall man in a dark coat. (宾从)5. When we will start is not clear.(主从)6. I had no idea who her best friend was. (同位)三、连接词四、解题技巧1. 划从句2. 判成分3. 定连词（顺句意）五、高频考点（一）that引导的定语从句与同位语从句Along with the letter was his promise that he would visit me this coming Christmas.Do you still remember the chicken farm that we visited three months ago.解析：在句①中，that引导同位语从句解释说明promise的内容，that不充当任何句子成分，只起连接作用，而在句②中，that在其引导的定语从句中作动词visited的宾语，对先行词the chicken farm起修饰作用。

第四讲名词性从句一、知识点拨（一）宾语从句（Object Clause）同学们在初中阶段时就开始接触宾语从句了。
当将一个直接引语转为间接引语时，就是在构造一个与“说”相关的动词后的宾语从句了。
在直接引语向间接引语转化的过程中，应就不同的句型类别进行不同的处理。
而不同的句型类别都应根据转述者和转述时间对宾语从句中的人称、时态及状语作相应的调整。
1.陈述句: 不需调整语序，只要对人称，时态或状语作一定的变化即可。
通常，若主句中的动词为过去时，则从句中的时态也要相应后退一格。
但如从句部分是客观真理，时态则务须变化。
如：①When the fox could not reach the grapes, he said, “The grapes are sour.”→ When the fox could not reach the grapes, he said that the grapes were sour.②She said, “Necessity is the mother of invention”→She said that necessity is the mother of invention.2.疑问句：可分为一般疑问句和特殊疑问句两类。
⑴一般疑问句: 转为if 或whether（是否）引导的宾语从句，且调整为陈述句语序，即主谓宾的顺序。
有时可用或whether … or not的结构。
如：“Do you want to insure your luggage or not?” he asked.⑵但当疑问词即是句子中的主语，则无需变换语序。
如：①“How are you getting along with your English study?” asked John.→ John asked me how I was getting along with my English study.②He asked, “What caused the accident?” → He asked what had caused the accident.3.祈使句: 可不再转为宾语从句，而是用“命令性动词+ 人称代词（宾格）/名词+ 不定式”的结构来表达相近的意思。
如：I said, “Keep a record of your expenses.”→4.”的结构。
如：She exclaimed, “What a silly boy you are!”→She told him what a silly boy he was.5.特殊结构：可根据句子的意思作灵活的变通。
如：①“You had better not leave your car unlocked,” said my friends, “there has been a lot ofstealing from cars.”→ My friends warned me not to leave my car unlocked as there had been a lot of stealing from cars.②British poet P.B.Shelly said, “If winter comes, can spring be far behind?”→British poet P.B.Shelly said that spring can’t be far behind if winter came.掌握了与“说”相关的动词后的宾语从句的构成，其它动词后的宾语从句也就不难理解了。
须注意两类动词：1. 表示说话者认知的动词：know, believe, think, explain, guess, hope, agree, understand, realize,suppose, expect 等动词后既可以跟that 引导的陈述分句作宾语，that常被省略；又可以跟疑问分句。
如：①One should know what’s what.② A straw shows which way the wind blows.值得注意的是：⑴有些表示猜想的动词后的从句中的否定式通常前移至主句中。
如：I don’t think he can do it better than me.⑵反意疑问句通常是对复合句中的主句发问，但若主句为I think／believe／suppose时, 则对从句发问。
如：We never thought she would play so well in the match, had we?I think you’ll come to the meeting, won’t you?⑶回答对think，believe，guess，hope等词提问的一般疑问句时，可用缩略式，即肯定回答用so；否定回答用not或don’t …so。
其中hope的否定回答只能用not。
如：Do you think / hope / guess / believe he will treat the child like that?Yes, I think / hope / guess / believe so.= Yes, I think / hope / guess / believe (that) he will treat the child like that.No, I don’t think / believe / suppose so.= No, I don’t think / believe / suppose (that) he will treat the child like that.No, I hope / believe / guess not.= No, I hope / believe / guess (that) he will treat the child like that.⑷wonder (想知道), doubt (怀疑)等动词本身带有不确定性，故后面多跟疑问分句。
注意，doubt在肯定句中，后接if或whether引导的宾语从句；在否定句和疑问句中后接that引导的宾语从句。
如：①I wonder who he is.②I doubt if / whether she is so vain and ignorant.I don’t doubt (that) she is so vain and ignorant.2. 表达说话者强烈意愿的动词：其后所跟的宾语从句须用虚拟语气。
⑴suggest，advise，order，demand，insist等动词后用“(that) … should do …”的结构，此时should可被省去。
如：Let us suggest to the person in crisis that he (should) cease concentrating so upon the dangers involved and the difficulties, and concentrate instead upon the opportunity- for there is always opportunity in crisis.⑵动词wish后的宾语从句多为不可能实现的愿望，故常将时态后退一格以示虚拟。
如：①I wish that all men everywhere could be free.②I wish she had taken my advice.3.⑴有些动词后带有宾语从句作为其直接宾语，同时带有一个人称代词或名词作为其间接宾语。
如：①He has informed me when they are to discuss my proposal.②She promised us that she would give us more help later on.③The company explained to their employees that a pay rise was out of the question.⑵在含有复合宾语“动词+ 宾语从句+ 宾语补足语”的结构中，往往因为宾语从句过长而将其放到句末，同时用it来充当形式宾语。
如：①We consider it absolutely necessary that we should open our door to the outside world.②I find it strange that he has not come yet.③He has made it clear that he won’t agree to the plan..④I heard it said that she had gone abroad.1.that引导的宾语从句一般不能直接跟在介词后面。
但须注意的是：⑴介词except，but，in后面可跟that引导的宾语从句。
如：①He is a capable man except that he has not enough experience.②I would come to see you but that I had something urgent to do then.③The higher income tax is harmful in that it may discourage people from trying to earnmore.⑵在有些含有介词的短语后可加上形式宾语it，再跟上that引导的宾语从句，形成depend on it that，rely on it that，insist on it that，see to it that等结构。
如：①I shall see to it that he is taken good care of when you are absent.②You can depend on it that I will try my best to get good grades at school.2.wh-词引导的宾语从句可以充当介词的宾语。
如：①We were astonished by what they found.②I walked over to where she sat.③I’m concerned about whether he has signed the contract or not.④I’m interested in when he did it.形容词后的名词性从句也被称作形容词补足语，多用于certain, sure, unaware, glad, afraid, frightened, happy, pleased, sad, sorry, surprised, upset 等表示认知或情感的形容词后。
