高考英语语法名词性从句讲解及练习
语法复习之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。
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。

最新高考英语语法必考考点(13)名词性从句
2019年高考英语语法必考考点（13）：名词性从句含解析李仕才【考点解读】一、名词性从句的种类名词性从句包括主语从句、宾语从句、表语从句、同位语从句。
二、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。
It has not been decided yet when we will leave.We are worrying about what we should do next.2．连接副词：when, where, why, how有词义，在从句中担任成分，作状语。
It makes no difference where we shall have the meeting.Scientists study how human brains work to make computers.(2012·四川高考) 3．连接词： whether, if, as if, if (whether), as if虽有词义，但在从句中不充当任何成分，只起连接作用；that无词义，在从句中也不充当任何成分，只起连接作用，有时可省略。
My suggestion is that we (should) have a discussion about this matter.The question whether we need more time to do the work hasn’t been discussed.三、that, what引导的名词性从句的区别引导名词性从句时，that没有词义，在从句中不作任何成分。
当从句意义完整，不缺任何成分时，往往选用that；而what引导名词性从句时，意为“什么”或“……的”，在从句中用来作主语、表语或宾语。
What was most important to her, she told me, was her family. (主语从句；what作主语)Before the sales start, I make a list of what my kids will need for the coming season. (宾语从句；what作宾语)As a new graduate, he doesn’t know wha t it takes to start a business here. (宾语从句；what作宾语)China is no longer what she used to be. (表语从句；what 作表语)It never occurred to me that you could succeed in persuading him to change his mind. (主语从句)One reason for her preference for city life is that she can have easy access to places like shops and restaurants. (表语从句)【点睛】(1)that引导主语从句时，常用it作形式主语，常见句型有：①it＋be＋形容词(如：obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, evident, clear, apparent等)＋that从句。
2019高考英语语法突破句法篇：从句与句式(定语、名词性从句、并列句和状语从句、主谓一致和特殊句式)
2.在定语从句中，当先行词指物时，下列情况的关系词用that而不用which： (1)当先行词是序数词或形容词最高级或被序数词、形容词最高级修饰时。 (2)先行词被all，every，no，some，any，little，much，the only，the very， few等修饰时。 (3)先行词为all，much，little，none，few，something，anything等不定代词时。 (4)先行词中既有人又有物时。 He was looking pleasantly at the children and parcels that filled his bus. (5)先行词在主句中作表语时。 The village is no longer the one that was 5 years ago. (6)当主句是以which开头的特殊疑问句时。 Which are the books that you bought for me?
[应对策略] 1.对于连词的考查，注意首先判断两个或两个以上的单词、短语或单句之间 是否有连词，再根据不同的句式结构，判断连词是否运用正确。解题时，可 以注意以下几个方面： (1)把握前后两句话之间的衔接关系，判定是并列句、名词性从句、定语从句 还是状语从句，根据连词在句中作何成分，判断正误； (2)注意but(转折)、and(并列)、or(或者/选择)、so(因此/结果)等逻辑关系词 之间的混用； (3)注意although/though/while不与but连用；since/as/because不与so连用。 2.遇到特殊句式，要注意主谓一致、强调句、倒装句、省略句、祈使句、感 叹句、反意疑问句等的构成特点。
从句与句式在短文改错中的考查
1.对于定语从句的考查主要涉及限制性定语从句与非限制性定语从句中关系 代词或关系副词的错用。 2.对于名词性从句的考查主要涉及连接词使用不当，缺少连接词以及what与 that、which混用等。 3.对于并列连词或从属连词的考查主要涉及连词使用不当，缺少连词以及多 余连词(although不能与but连用，because不能与so连用)等情况。 4.对于特殊句式的考查主要涉及主谓不一致、含有助动词的谓语结构错误和 替代词的错用等。
高中英语语法解析---名词性从句
高中英语语法解析---名词性从句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It is reported that…据报道…It has been proved that…已证实…It is said that…据说…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。

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。

高考英语语法填空真题分析之名词性从句连词专题
高考英语语法填空真题分析之名词性从句连词专题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四种。
名词性从句连接词的选择是考查的重点。
名词性从句连接词的选择可从连接词在从句中的作用（即成分）和意义两个方面入手：一是连接词在从句中作不作成分，如果作成分，作什么成分；二是连接词在从句中有无意义，如有意义，是何意义。
具体见下表：1.that引导名词性从句that引导名词性从句时，在从句中不作成分，也没有任何意义。
1. 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. (2019全国I)【答案】that【解析】句意：虽然在北纬88度以北它们较为罕见，但是有证据表明，它们的活动范围延伸到北极，向南延伸至加拿大的詹姆斯湾。
there is evidence是一个there be句型，后面又是一个句子，所以空白处应填连词；这是一个同位语从句，连接词在从句中不作成分，也没有意思，所以用that引导。
2. It is possible _________ caffeine may cause birth defects (缺陷) in humans, too. (2018浙江) 【答案】that【解析】句意：咖啡因也有可能婴儿一出生就带有缺陷。
这是一个复合句。
it是形式主语，真正的主语是后面的从句，所以这是一个主语从句，连接词在从句中不作成分，也没有意义，故填that。
3. The most pleasant thing of the rainy season is ___________ one can be entirely free from dust. 【答案】that【解析】句意：雨季最惬意的事情就是人们可以远离尘土。
高中英语 高考语法易错知识点15.名词性从句(考点梳理+易错点)
名词性从句知识梳理1. 名词性从句的概念名词性从句是在句子中起名词作用的句子。
名词性从句的功能相当于名词词组，它在复合句中能充当主语、宾语、表语和同位语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句，表语从句，宾语从句和同位语从句。
2. 名词性从句的连接词★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（是否），as if（似乎）虽有词义，但在从句中不担任成分。
★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。
易错知识点1. 误用名词性从句的连接词名词性从句的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（好像）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）。
1.1 易错例题 1At first he hated the new job but decided to give himself a few months to see ____ it got any better.A. whenB. howC. whyD. if【陷阱】考生容易误选A，混淆名词性从句中的连接词和连接副词的使用，认为是看什么时候情况会变得好一点。
【分析】最佳答案D，句子的意思是：最初他不喜欢这份新工作，但是他决定给自己几个月的时间来看一下这件工作是否会变得更好。
see后面是名词性从句中的宾语从句，且宾语从句中成分完整，故用if引导宾语从句。
【考题再现】What the doctors really doubt is _____ my mother will recover from the serous disease soon.A. whenB. howC. whetherD. Why【陷阱】考生容易误选B，注意文中表达的是“是否”之意，而非“怎样”。

2.【2018·北京】33.I truly believe ______beauty comes from within.A. thatB. whereC. whatD. why【答案】A【解析】试题分析：句意：我很相信美丽源自于内心! 本题考查宾语从句。

【考点定位】考查名词性从句。
【名师点睛】名词性从句分多种，宾语从句在考试中也是很常见的，要注意宾语是句子的一个重要成分，它可以由名词、代词、名词短语或句子充当。

一般情况下，宾语从句可作谓语的宾语，也可做主语的宾语。

高考英语语法专攻-《名词性从句》-考点归纳+针对性练习
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。
高考英语高中英语语法之【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？】上一章，我们了解的是定语从句，加上我们以前了解的宾语从句和状语从句，好像“名词性从句”这个概念本身就和我们所熟知的概念不是一路货色。
没错。
请看下表：根据从句在句子中的功能分根据从句的性质分定语从句形容词性从句主语从句名词性从句宾语从句表语从句同位语从句状语从句副词性从句只是，在平时老师讲课时，形容词性从句和副词性从句并没有形成气候罢了。
相比之下，名词性从句由于“家丁兴旺”而大行其道。
但是，作为学生，我们有必要了解这些基本概念的来龙去脉。
【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。
