名词性从句专项复习主语从句、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, wh- ever名词性从句连接词的采纳一、 that和what的采纳：that和 what 都可引导全部的名词从句。
但是，what 除起连接作用外，还在名词性从句中充当成分，可做从句的主语、宾语、或表语。
而that 在名词性从句中不充当任何成分，只起连接作用。
二、 if 和 whether的采纳不能够使用 if 的情况：a. 主语从句句首b.表语从句，同位语从句c. if 引起歧义d. 介词后的宾语从句e. 与 to do 连用 f .whether or not 连在一起引导宾语从句时不用if三、其他连接代词和副词的连用主要依照名词性从句中的详尽意义,正确的选择 who 、 which 、 when 、 where 、why 、how等连接词，这些连接词既拥有疑问含义，又起连接作用，同时在从句中充当各种成分。
四、引导词 that 的省略that可省略的情况：单个宾语从句中的that 可省略that不能省略的情况： a.主语从句 b.表语从句 c.同位语从句 d.用 it 做形式宾语的宾语从句 e.并列的宾语从句中，后几个从句的引导词that 不能够省略五、同位语从句的引导和区分1.同位语从句的格式：n.+连接词 +从句2.能接同位语从句的名词有：fact 、 idea, news, information, order, belief, suggestion, advice等.3.连接词平时是 that, 也可依照含义采纳whether, what, when, where 等来引导同位语从句 .4.中心词是“建议、建议、命令〞从句要用虚假〔should 〕 do六、同位语从句和定语从句的差异1.定语从句是先行词的修饰语。
高考语法填空抢分热点之名词性从句一、考点精讲名词性从句的引导词：1.that 无词义，只起引导作用，可以省略，但两个或两个以上that引导的宾语从句并列时，从第二个开始that不能省略。
2.what引导名词性从句，既起引导作用，又在从句中作一个成分，起双重作用，不能省略。
3.连词whether“是否”，可以引导主语从句、表语从句、介词之后的宾语从句以及同位语从句，而if“是否”只能引导动词后面的宾语从句。
4.引导名词性从句的连接副词有when、where、how、why，在判断名词性从句引导词的使用时，如果句子缺成分，缺什么，补什么。
二、高考题经典解读1.______(56) is so breathtaking about the experience is the out-of-this-world scenes.【答案】What【解析】考查主语从句。
句意：这段经历最让人激动的是那些脱离世界的场景。
设空处无提示词，应考虑填冠词、介词、连接词，又因为空格在句首，后面是谓语动词is，这里应该填一个连接词，引导主语从句，从句缺少引导词和主语，且指物，所以连接代词What符合语境，其双重作用。
位于句首，首字母用大写。
故答为What。
2.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。
句意：虽然它们在88℃以北很少见，但有证据表明，它们一直分布在北极，南至加拿大的詹姆斯湾。
该句是含让步状语从句的复合句，主句部分是there be句型，设空处填that，引导同位语从句，说明evidence的具体内容。
故答案为that。
3.Research suggests an increase in voice is a signal ________ someone is lying.【答案】that【解析】考查同位语从句。
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。

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.3.一般不用if引导表语从句，用whether.The question is whether we can reduce the cost of the product.4.其他连接词：as if ,as though,because,as,like.It sounds as if/though he has been really ill.5. 主语为reason：表语从句中的连接词要用that，不用why.The reason why he was unhappy is that he has lost his keys.6.表语从句中的虚拟语气.（四）宾语从句1、宾语从句在复合句中作宾语。

句意：对这位球星来说最好的时刻就是他射门得分的时候。
Where表示地点，how表示方式，why结果；只有when表示的是时间。
故B 正确。
【试题延伸】表语从句就是用一个句子作为表语。
说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。
解答这类题目，关键在于分析清楚句子结构。
通过判断引导词在从句中所作的成分及意义，来选择正确的引导词。
连接表语从句的从属连词主要有that, if, whether，和疑问词（what how where when ...)。
that引导表示陈述句的表语从句，if和whether，whether...or not引导表示“是否”，引导一般疑问句。
连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。
连接代词一般指疑问，但what, whatever除了指疑问外，也可以指陈述。
连接副词主要有when, where, why, how, whenever, wherever, however等.【举一反三】I am afraid he’s more of a talker than a doer, which is ______ he never finishes anything.A. thatB. whenC. whereD. why【答案】D【考点】考查表语从句。

语法专题：名词性从句(1课时)【学习目标】1.自主学习名词性从句的基本用法并学会在具体情境中的运用；2.通过自主学习和小组合作尝试发现式方法去学习掌握名词性从句的用法；3.团结协作、发挥所长、激发创新、攻克难题。
【使用说明与学法指导】1.五分钟完成预习案的学习，五分钟内回顾名词性从句并用自己的话来总结；2.独立思考限时10分钟完成探究案，20分钟内完成反馈案；3.认真书写，独立完成，规范作答，按时上交。
预习案（Previewing Case）Activity 1 Read the following materials in 5 minutes.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。
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。
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：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。
2. 宾语从句作句子宾语的从句叫宾语从句。
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。
2020 年高考英语真题/模拟题+答案+解析（名词性从句、状语从句、定语从句）一、2020 年高考真题1、（2020 天津高考真题）The student completed this experiment to make come true __________ Professor Joseph hadsaid.A. thatB. whatC. whenD. where【答案】B【解析】考查名词性从句。
句意：为了使约瑟夫教授所说的成为现实，这个学生完成了这个实验。
_________ Professor Joseph had said 作make 的宾语从句，该从句中，空处在从句中作said 的宾语，表示”..所说的话”，因此应用what 引导该从句。
故选B。
2、（2020 新课标Ⅲ卷高考真题）In ancient China lived an artist 61 paintings were almost lifelike.【答案】whose【解析】考查定语从句。
句意：中国古代有一位画家，他的画几乎栩栩如生。
此处为定语从句修饰先行词artist，且先行词在从句中作定语，故应用关系代词whose。
故填whose。
3、（2020 江苏高考真题）Many lessons are now available online, from __________ students can choose for free.A.whoseB. whichC. whenD. whom【答案】B【解析】考查定语从句。
句意：许多课程现在都可以在网上找到，学生们可以从中免费选择。
此处是非限定性定语从句，先行词是many lessons，关系词在从句中做介词from 的宾语，应使用关系代词which 引导。
故选B。
4、（2020 江苏高考真题）It is not a problem __________ we can win the battle; it’s just a matter of time.A. whetherB. whyC. whenD. where【答案】A【解析】考查主语从句。
名词性从句名词性从句一．概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、表语从句、宾语从句和同位语从句。
四．if, whether的区别1.引导主语从句时，如果主语从句放在句首，只能用whether不能用if引导，但是如果用it 做形式主语，而把主语从句放在句末时，也可以用if引导.2.引导宾语从句时常放在动词know, ask, care, wonder之后，if和whether均可。
3.在介词后面的宾语从句中，在表语从句、同位语从句中，表“是否”，只能用whether；4.whether和if都可以和or not连用,但是whether 之后可以直接跟or not,而if不可以。
I don’t know whether or not I will stay.（只能用whether）5.在不定式前只能用whether.如：I can’t decide whether to stay. 我不能决定是否留下。
五．与“命令、要求、建议”等相关的名词性从句中通常用虚拟语气，虚拟语气的构成是“should＋动词原形”或省去should，直接用动词原形。
六．名词性从句以考查引导词为主，同时考查时态，语序，与其它从句的区别以及混同虚拟语气的考查。
一．主语从句1.主语从句定义：在复合句中充当主语的句子叫做主语从句。
That he will succeed is certain.Whether wild life can be well protected is of great importance.Who will go makes no different.Which kind of food is the best is still not certain.What is needed for the space trip is careful preparation.How we can help the twins will be discussed at the meeting.When they’ll start the project has not been decided yet.Where he hid the money is to be found out.Why dinosaurs died out remains a puzzle.2.主语从句引导词按照在句中是否做成分主要分为三类：连词that、whether、if 连接代词、连接副词。
高考英语复习语法知识专题讲解专题十专题十五五 名词性从名词性从句句名词性从句的句法功能相当于名词词组，在句中充当主语、宾语、表语、同位语、介词宾语等。
因此名词性从句又分为主语从句、宾语从句、表语从句和同位语从句。
类别功 能 引 导 词 从属连词只起连接作用，不充当句子成分 that, whether, if 连接代词 起连接作用，并充当主语、宾语、表语或定语 who, whom, whose, which, what, whatever, whichever,whoever连接副词 起连接作用，并充当从句状语when, where, how, why 一、主语从句的易错点主语从句的一般结构主语从句＋谓语动词＋其他 How the book will sell depends on its author. That he is the best student in the class is obvious.it 作形式 主语时的主语从句 It+be/becomes/became+形容词／名词／过去分词＋主语从句 It is still a question whether she will come or not. It became clear that Mary did make a mistake. It seems/ appears/ happens 等动词＋that 从句 It seems strange that he should have done a thing like that. It happens that he can understand a little about thelanguage. It remains to be+过去分词＋主语从句It remains to be seen who will be the victor in the contest.It doesn't matter +how/whether 从句 It doesn't matter whether he is wrong or not.It doesn't matter much whether we go together orseparately.用来表示惊奇、怀疑、惋惜、理应如此等语气时，主语从句谓语动词用（should) do 形式 It is necessary /important / natural /strange 等＋that 从句It is necessary that one(should)obey the law.It is suggested /requested /proposed/desired 等＋that 从句It is suggested that you (should) attend the openingceremony.二、宾语从句的易错点动词后的宾语从句主语＋及物动词＋宾语从句I know that he is an honest boy.Can you tell me how I can get to the zoo?I wonder if/whether you have told the news to Li Lei.They asked what Jean was doing now.Do you know who has won Red.Alert game?feel, think, find, consider, make等，常用it作形式宾语，宾语从句后置I find it important that.we should keep calm in danger.You may think it strange that he would live there.I feel it a pity that I haven't been to the get-together.I have made it a rule that I keep diaries.like, dislike, love, hate, enjoy,appreciate等不能直接跟宾语从句，必须用it作形式宾语，后接宾语从句I like it that everyone passed the exam.I hate it when they talk with their mouths full of food.think, believe, suppose, 等词后的宾语从句若是否定的，否定词要转移到主句的谓语动词上I don't think your answers are right.I don't believe that man is killed by Jim, is he?介词后的宾语从句介词后可接宾语从句，但连接词whether 不可换作ifHe often thinks of how he can make his class lively.She worries about whether she's really good enough.非谓语动词之后的宾语从句不定式、v.-ing形式、过去分词后也可以接宾语从句I'd just tried to do what I could for you.I suggest eating what is fresh.宾语从句中的时态主句谓语动词为一般现在时，从句时态根据实际情况而定Do you know when the ancient games began?主句谓语动词是一般过去时，从句的时态一般用适当的过去时态He asked me if I was reading the textbook when he wasin.当宾语从句为客观真理和规律时，则用一般现在时He said that light travels faster than sound.whether与if 引导宾语从句的区别与 or not 连用时，只用 whether I want to know whether or not the train goes to KingStreet.＂whether+不定式”结构作宾语，相当于一个宾语从句；if无此用法I don't know whether to go there.介词后面的宾语从句中只用whetherI'm not interested in whether he has a lot of money.if引导的条件句中，如果再有表示“是否”的引导词引导宾语从句时，只用 whetherHe asked me whether I'd move to Beijing if I got the job.doubt 在肯定句中，接whether 和if引导的宾语从句；但在否定句中，只用 thatWe don't doubt that he is a brave man.I doubt whether/if Jack could manage a sailing boat.三、表语从句的易错点表语从句常位于连系动词be, look, remain, seem等之后，其连接词还有as if/though,because等主语＋系动词＋表语从句The trouble is that we are short of money.He looked just as he had looked ten years before. The question is whether they will be able to help us. The problem is who we can get to replace her.I think it is because you are doing too much.The question is which of us should go.because 引导表语从句强调原因，why引导表语从句强调结果It's because you're careless.That is why stone walls are used instead of fences around New England fields.the reason why 从句＋be + that 从句The reason why he was absent was that he was ill.what 从句＋be+that从句What comforted the young mother was that the babycame to life.It looks/seems as if/though 从句It looks as if it is going to rain.At that time, it seemed as if I couldn't think of the right word anyhow.主句主语是advice, demand, suggestion, order，requirement, idea, request，command等时，表语My advice is that you(should)quit smoking.从句用虚拟语气，即谓语动词用（should)do 形式My suggestion is that we(should)start early tomorrow. Our only request is that this(should)be settled as soon as possible.四、名词性从句其他易错点that与what 在名词性从句中的区别what 充当成分，意为...的事物不可省略；that 不作任何成分，只起连接作用，也无实际意义，有时可以省略I only knew(that)he was studying in a western country,butI didn't know what country he was in.What you need is more practice.That you will win the medal seems unlikely.名词性从句已有疑问引导词时，不再用thatI don't understand what you said just now.(understand 后不再用 that)2021高考英语语法高考英语语法【【名词性从句名词性从句】】易错点对点训练30题I.高考真题诊断·单句语法填空1.Every year, makes the most beautiful kite will win a prize in the Kite Festival.2.She asked me I had returned the books to the library, and I admitted that I hadn't.3.The manager put forward a suggestion we should have an assistant.

专题十四名词性从句重难点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，可作主句的主语、宾语、表语和同位语。
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（见下表）。
一、主语从句主语从句是在复合句中充当主语的从句，通常放在主语谓语动词之前或由形式主语it代替，而本身放在句子末尾。
如：Who will go is not important. 谁将去不是重要的。
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每一部分进行强调，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。
如：It is a pity that you didn’t go to see the film. (主语从句) 你没去看电影真是遗憾。
It is in the morning that the murder took place. （强调句）谋杀案发生的时间是在早晨。
2. 用it作形式主语的结构2. 主语从句不可位于句首的五种情况二、宾语从句宾语从句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。
注意：that引导的从句常跟在某些形容词后作宾语，如：anxious, aware, certain, confident, convinced, determined, gald, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, satisfied, content等。
也可将此类词后的从句看作是原因状语从句。
三、表语从句表语从句是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”。
专题三名词性从句名词性从句指在复合句中起名词作用的从句，它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教学的重点，也是高考考查的热点。
一、名词性从句的分类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。
其连接词有 that, if, whether；连接代词 who, what, which；连接副词 when, where, how, why 等。
考查热点一：对主语从句的考查主语从句在复合句中充当主语，它可以放在主句谓语动词之前。
但为了保持句子平衡，多数情况下可用it 作形式主语，而把主语从句置于句尾。
考查热点二：对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语。
如果主句的谓语动词是及物动 make, find, see, think 等，则把宾语从句置于宾语补足语之后，用it 作形式宾语。
另外，某些作表语的形容词，如 sure, happy, glad, certain 等之后也可以带宾语从句。
考查热点三：对表语从句的考查表语从句在句子中作表语，位于主句中的系动词之后。
考查热点四：对同位语从句的考查同位语从句一般跟在某些抽象名词之后，进一步说明该名词所表示的具体内容。
可跟同位语从句的名词主要有：fact, idea, news, promise, belief, condition, doubt, fear, hope, problem, proof, question, reply, report, suggestion, thought, truth等。
二、对名词性从句的考查应注意以下几点：考查热点五：考查名词性从句的语序和主从句时态名词性从句均应用陈述句语序，其时态要保持主从句时态一致性。
考查热点六：从语境和句子结构需要出发，选择合适的连词（I）连词that 和what：that 无实际意义，在从句中不充当任何成分，只起连接主从句的作用；如 that 引导宾语从句，常可省略；如引导主语从句、表语从句或同位语从句， that 不能省略。

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每一部分进行强调，无论强调的是什么成分，都可用连词that。

也可将此类词后的从句看作是原因状语从句。
三、表语从句表语从句是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。
引导表语从句的引导词that一般不省略。
另外，常用的含有表语从句的结构还有“The reason is that…”，“It is because…”，“That’s why…”等。
如：The reason he is late for school is that he missed the early bus. 他上学迟到的原因是他错过了早班车。
四、同位语从句同位语从句是在复合句中作名词的同位语的名词性从句。
五、whether, if引导名词性从句的区别注意：doubt作“怀疑”解，后接宾语从句时，如主句是肯定的，宾语从句用whether或if引导，如主句是否定，宾语从句只能用that引导。
如：I doubt whether/if he is fit for the job. 我怀疑他是否胜任这份工作。
I don’t doubt that he can do it very well. 他能把它做好，我不怀疑。
