高考英语一轮复习语法点专题讲解名词性从句名词性从句名词性从句包括主语从句、表语从句、宾语从句、同位语从句。
其关联词有连接词that，if，whether；疑问代词who，what，which和疑问副词when，where，how，why等。
1.主语从句主语从句在句中做主语。
它可以放在主句谓语动词之前，但多数情况由it作形式主语，而把主语从句放在主句之后。
例如：Who did that is known to all.It is interesting that you should like him.2.表语从句表语从句在句中作表语，位于主句中的系动词之后。
如：The question is who can complete the difficult task.表语从句不能用if引导，但可用as if引导。
例如：He looked as if he was going to cry．3.同位语从句同位语从句跟在名词后面，进一步说明该名词的具体内容。
引导同位语从句的名词主要有fact，news，promise，idea，truth等。
连接词用that（不用which），及连接副词how，when，where，why等。
例如：His delay is due to the fact that the car went wrong halfway．The news that our team has won the match is true.She asked the reason why there was a delay．4.宾语从句1.宾语从句在句中作及物动词或介词的宾语。
例如：We can learn what we did not know．He will talk to us about what he saw in the U.S.如果主句的谓语动词是及物动词make，find，see，hear等，则把宾语从句置于宾语补足语之后，用it作为形式宾语。
高考英语名词性从句高频考点易混点高频考点一：考查that与what的区别在引导名词性从句时，从属连词that一般要注意三个"不"：1.不省略。
当从属连词that引导的主语从句位于句首时，that不省略；that引导同位语从句时，一般不省略。
2.不作成分。
that 在名词性从句中不作任何句子成分。
3.无实义。
that 在名词性从句中没有实义。
在引导名词性从句时， what一般要注意一个"不",一个"有词义",一个"作成分"：1.不省略。
what 引导名词性从句时，不省略。
2.有词义。
what 引导名词性从句时，有词义。
一般表示"……的东西/事情等"，这一用法与that 的用法不一样。
3.作成分。
what 在引导名词性从句时，在从句中充当成分。
这一用法与that 的用法不一样。
例如：Nobody believed his reason for being absent from the class that he had to meet his uncle at the airport.该句中，that引导同位语从句，在句中不作任何成分，不能省略且无词义。
What the teacher said had a good effect on the children.what引导主语从句，在句中有词义。
高频考点二：it放在句首，真正的主语是that从句常用句型如下：① It+系动词+n.+ that从句;② It+系动词+adj.+ that从句;③ It+be+动词的过去分词形式（如said, reported, suggested等）+that从句；④ It+特殊动词（appear, seem, happen, matter, turn out, work out等）+that从句。
高频考点三：考查whether与if的区别whether与if在作"是否"讲时,是可以互换的。

4.【名词性从句从句命题预测】2024年语法填空对名词性从句的考查仍是重点，主要集中考查名词性从句的引导词的用法，如连接词that和what的用法、whatever 和whichever、if和whether等。
5.【名词性从句思维导图】【名词性从句从句考点梳理】6.考点清单一、名词性从句的种类、语法功能和引导词英语中从句主要分为三种：名词性从句（用从句代替名词）、定语从句（用从句代替形容词）、状语从句（用从句代替副词）。
名词性从句就是指从句在主句中充当名词成分，其功能相当于名词性词组。
1）根据从句在句子中不同的语法功能，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。
2）根据名词性从句的引导词不同，可分为：that从句、if/whether从句和wh引导的疑问句（who/whom/whose/whoever/what/whatever/which/whichever/where/when/how/why等）。
一．概念：名词性从句就相当于一个名词（因为名词可以充当主语，宾语和表语，所以名词性从句包含主语从句，宾语从句和表语从句和同位语从句）二．名词性从句主语从句That she is beautiful is a fact.主语从句系定表宾语从句We know that she is beautiful.主谓宾语从句表语从句 Our opinion is that she is beautiful.主系表语从句同位语从句The opinion that she is beautiful is a fact.主同位语从句系定表三．名词性从句的格式 1. that+陈述句=名词宾1.结构：主语 + 谓语2.语序：陈述句语序3.连接词 :①由that 引导②由if /whether 引导know if / whether Hua likes fish.③由特殊疑问词引导，表示特殊疑问意义 I want to know what time it is now.4.时态①当主句是一般现在时，从句根据情况使用任何时态。
（即：主现从不限）I don’t know (that) she is singing now.②当主句是一般过去时，从句应使用过去某时态(一般过去时,过去进行时，过去将来时，过去完成时)。
He said (that) he was at home. 他说他在家里。
③主句使用一般过去时，但从句表示的是客观真理、自然现象时、从句仍用一般现在时。
The teacher told us light travels faster than sound.一、一般结构：主语+连系动词+表语从句，二、可以接表语从句的词有：①be(being, been, am ,is, are, was, were)（be动词）② feel,look,sound, taste, smell (感官动词）③ stand, lie,remain, keep, stay(保持动词）④bee, get, grow, turn ,go ,prove(变化动词）⑤ seem, appear(表象动词)三、公式：a.由连接词that（无意义）, whether（是否）引导的表语从句这时主句的主语常常是抽象名词，如problem, result, chance, suggestion, question, reason 等，表语从句对主句主语进行说明，解释等。
高考英语名词性从句知识点一、that从句1、主语从句that从句作主语时，常用it作形式主语，常见的句型有：It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc. ) + that 从句It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc. ) + that 从句It+be+过去分词(said, reported, thought, expected, decided, announced, arranged,etc. ) + that 从句that可以省略，但that从句位于句首时，that不能省略。
2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid 等。
在可以接复合宾语的动词之后,如think, make, consider等，可以用it作形式宾语。
(2)That从句一般不能充当介词宾语，偶尔可作except, in的宾语。
3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时，应在某些抽象名词之后,如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility 等，对前面的名词起补充说明的作用，that 在从句中不担当任何成分，不能省略。
二、whether/if 从句1＞在表语从句和同位语从句中，只能用whether不能用if；当主语从句放于句首时，只能用whether不用if；当it作形式主语，主语从句放在句末时用whether或if均可；discuss后引导宾语从句时，必须用whether。
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。
一、什么是表语( predicative)在形式上，位于系动词后的就是表语。
从含义上讲，表语是回答主语“是什么”或“怎么样”的语法成分。
即是指“是”字句“是”字后面的成分。
表语就是起表述作用的句子成分。
它修饰的是主语。
表语是用来说明主语的身份、性质、品性、特征和状态的。
表语须和连系动词一起构成句子的复合谓语。
表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当，它常位于连系动词( be, become,appear, seem等)之后。
Albert Einstein was a famous professor of physics.二、不定式、动名词与分词作表语的区别不定式和动名词作表语相当于一个名词作表语，含义是回答主语“是什么”；分词作表语相当于形容词作表语，含义是回答主语“怎么样”。
考点七十名词性从句1．名词性从句必须采用陈述语序。
①I want to know what he has told you．我想知道他告诉了你什么。
②She always thinks of how she can work well．她总是在想怎样能把工作做好。
2．it充当形式主语或宾语：在名词性从句中，为了使句子保持平衡，常用先行词it来代替主语从句或宾语从句，而把主语从句或宾语从句放到后面，尤其是连词that引导的主语从句常用于此句式中。
①It 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。
②I find it strange that she doesn’t want to travel．她竟不想旅游，我觉得很奇怪。
3．在名词性从句中that与what的差异：what在从句中要充当某个成分(主语、宾语或表语)，在任何情况下都不能省略，表示＂(＝the thing or things that...; whatever)……的事物；无论什么；凡是……的事物＂。
that本身没有词汇意义，在从句中不充当任何成分，在口语和非正式文件中，宾语从句中的that常常省略。
①What you have done might do harm to others．你所做的事或许对别人有害处。
②I spent what little time I had with my family．我仅有的一点儿时间都和家人在一起度过了。
③No one knows what will happen next．谁也不知道下一步有什么事。
④I think(that) you will like the stamps．我认为你会喜欢这些邮票的。
4．whether和if的差异：（1）引导主语从句、表语从句或同位语从句，只能采用whether。
☞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。

高考英语一轮复习——名词性从句（附答案）I. 考点分析名词性从句包括：主语从句、宾语从句、表语从句、同位语从句，多由连词that，wh- 疑问词或由what，whatever等关系代词引导，其中同位语从句在高考考试中最常见。
1. 主语从句1) 主语从句在句子中充当主语，句子的谓语动词用第三人称单数。
如：Why he refused to work with you is still mystery.Whoever comes is welcome.2) 主语从句前的that不能省略，仅起连接作用，有时为了保持句子平衡，that从句后置，而由it作形式主语。
如：That he became a lawyer may have been due to his mother’s influence.It is not true that he has moved to New York.2. 宾语从句在句子中充当宾语，如：I don’t know where the sound came from.Don’t be satisfied with what you have achieved.3．当从句放在系动词be, look, remain, seem等后即构成表语从句。
The trouble is that I have lost his address.It seemed that the night would never end.4. 1) 同位语从句是对与之同位的名词中心词作进一步解释，能接名词性从句的常见名词有: idea, fact, news, belief, hope, evidence, opinion, problem, truth, answer, proposal, theory, decision, discovery, problem, thought, understanding 等。
名词性从句知识点汇总一、名词性从句的分类名词性从句，包括四种从句，即主语从句、宾语从句、表语从句、同位语从句。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成，所以这四种从句在主句中都充当了名词的作用，故将这四种从句统称为名词性从句。
如：1.That she will help me made us happy.（主语从句）2.I can understand what he said.（宾语从句）3.This is where I was born.（表语从句）4.The fact that a heavy earthquake happened made me crazy.（同位語从句）二、名词性从句的连接词分类1.that（无含义，不充当成分）2.whetherif（有“是否”的含义，但不充当成分）3.连接代词：what whatever who whoever whom whomever whose which whichever.（在从句中做主语、宾语、表语和定语）连接副词：when whenever where wherever how however why （在从句中做状语）4. as ifas thoughbecause（不充当成分，在名词性从句中只引导表语从句）三、连接词that在名词性从句中可以省略的三种情况1.it 做形式主语，that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。
2.动词后面的宾语从句中I think(that) you have much to improve in English.我认为你的英语需要提高的有很多。
3.形容词后面的宾语从句中I am afraid (that) I will be late.恐怕我要迟到了。
四、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。
高中英语语法专攻-《名词性从句》【考点1-引导词】【考点2-主语从句】①定义：主语从句是指在复合句中充当主语的句子，它是名词的拓展，属于主语的第三个表达层次。
所以，主语从句和名词一样通常是出现在谓语动词的前面。
②主语从句的引导词：从属连词：that、whether、if（不可位于句首）连接代词：what, whatever/who, whoever/whom, whomever/whose,whosever/which,whichever连接副词：when, whenever/where,wherever/how, however/whythat引导主语从句（that无含义，在句中不作成分，不可省略）That youth is wholly experimental is known to us all。
众所周知，青春就是探索的岁月。
That she finished reading an English novel surprised us all.她读完了一部全英文小说让我们惊讶That you will win the medal seems unlikely.你赢得奖牌似乎是不可能的。
That he is still alive is a wonder.他还活着，真是奇迹。
That we shall be late is certain.我们要晚了，这是确定无疑的。
That she is still alive is a consolation.她还活着是使人感到宽慰的。
Whether引导主语从句（whether有含义“是否”，在句中不作成分，不可省）Whether she will come to the party makes no difference.她来不来参加聚会都没有关系。
It makes no difference whether/if she will come to the party.W hether he is coming or not doesn’t matter too much.他来或不来都不怎么重要It doesn’t matter too much whether he is coming or not.Who,whom, what, which,whose（连接代词）引导主语从句（连接代词有含义，在句中起名词性作用，担当一定成分）Who will be the leader of the team has not been decided yet.谁会成为这个队的领头人还没定下来。
高考英语名词性从句用法详解一、考点分析在复合句中具有名词的性质的作主语、宾语、表语、同位语的从句叫名词性从句。
因此，我们把主语从句、宾语从句、表语从句和同位语从句这四种从句统称为名词性从句。
名词性从句的高考考点考点引导名词性从句的关联词、名词性从句句法结构、定语从句与同位语从句的区别二、专题讲解知识点1）引导名词性从句的关联词：1．从属连词：that , if ,whether① that 本身没有意义，在从句中不做任何句子成分。
引导单个宾语从句时，that可以省略。
但引导主语从句、表语从句、同位语从句与形式宾语it并存的宾语从句时，that都不能省略。
如果引导两个或两个以上宾语从句，第一个that可以省略，从第二个宾语从句起向后的从句中的that不能省。
例如：1. I don’t think （that）she is coming. (可省)2. The reason is that he is careless. （不能省）3. The news that our team won the match inspired us.（不能省）4. I don’t think it necessary that you should read English aloud. （不能省）5. He told me （that）his father had died and that he had to live alone.（第一个可省，第二个不可省）②.从属连词whether 和ifWhether 和if 是“是否”的意思，在从句中不担当句子成分。
引导宾语从句时（动词后面的宾语从句）二者可以换用，若宾语从句提前只用whether. 但引导主语从句、表语从句、同位语从句、介词后的宾语从句，及紧跟or /or not 结构或不定式时，只能用whether.①He wants to know whether or not you agree.②He doesn’t know whether to stay or not.③He wondered whether to accept or refuse.④It all depends on whether they will do their best.⑤Whether she will come or not is still a question .⑥The question is whether it is worth doing.⑦None of them can answer the question whether it is worth doing.2 .连接代词：who , whom, what , which , whose 及whoever, whomever, whatever, whichever既保留原意，又在从句中担当句子成分。
高中英语名词性从句知识点（含练习）基础回顾1.表语：表语用来说明主语的身份、性质、品性、特征和状态的，表语常由名词、形容词、副词、介词短语、动词的-ing、不定式、从句来充当，它常位于系动词(be, become, appear, seem,look,sound,feel,get,smell等词)之后。
如：Her job is selling computers. 此句表语为selling computers如果句子的表语也是由一个句子充当的，那么这个充当表语的句子就叫做表语从句。
2.同位语：一个名词(或其它形式)对另一个名词或代词进行解释或补充说明，这个名词(或其它形式)就是同位语。
如Mr. Smith,our new teacher,is very kind to us. 我们的新老师史密斯先生对我们很好。
Mr.Smith是主语our new teacher的同位语，指同一人。
同位语从句I heard the news that our team had won．我听到了我们队获胜的消息。
that our team had won 解释news的具体内容，是同位语正文一、定义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。
That he finished writing the composition in such a short time surprised us all他在很短的时间内写完作文让我们都很惊讶 (主语从句)The trouble is that she has lost his address. 麻烦的是她把他的地址搞丢了。
（表语从句）They have no idea at all where he has gone. 他们不知道他去什么地方了。
（同位语从句）Do you remember how he came? 你记得他怎么来的么？（宾语从句）二、语序名词性从句要采用陈述句语序。

He said…→He said _____________________________.2) Do they speak English? We want to know…→We want to know __________________.3) What is her name? He asks me…→He asks me _________________________.注意:在think, believe, suppose, expect等动词之后, 宾语从句中谓语的否定常转移到主句的谓语上如：I don’t think he will see you. We don’t expect he is coming.我相信他不会走。
考点2．时态1. 如果主句是的时态(包括, )那么从句的时态一定要用。

如: Whether we shall attend the meeting hasn’t been decided yet.It hasn’t been decided whether (if) we shall attend the meeting.2)表语从句如：The question is whether the film is worth seeing.同位语从句如：The news whether our team has won the match is unknown.3)介词之后的宾语从句。
(介词往往可以省略)如：It all depends (on) whether they will support us.4)后面直接跟动词不定式时，即whether to do。
