高考英语第二轮热点专题复习——名词性从句
高考英语语法之名词性从句
1.名词：表示人或事物的名称的词叫名词。 2.名词的句法作用：名词在句中主要作主语、宾 语、表语和同位语。另外还可以作定语、状语。 3.名词性从句： 在英语的句子结构中，本来该由名词充当的主 语、宾语、表语和同位语，由一个句子来充当， 这个句子就叫名词性从句。 4.名词性从句的种类： 根据名词性从句在句子中所充当的不同成分， 名词性从句可以分为主语从句、宾语从句、表 语从句和同位语从句。
2.When he will go to America is not yet fixed.

超实用高考英语复习：高考语法填空抢分热点之名词性从句(解析版)
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。

(4)whether可以引导同位语从句，用以说明前面的名词的内容，if则不能。We ought to discuss carefully the question whether we can do it or not.(5)whether常与or连用表示一种挑选，if不能这样用；whether也可与动词不定 式连用但if不能。The question of whether they are male or female is not important.I have not decided whether to go or not.(6)间接宾语位于句首时 或者间接宾语提早时用whether不用if。Thank you，but whether I'll be free I'm not sure at the moment.(7)whether可引导一个让步状语从句表示“不管”、 “不管”，而if不能。Whether he comes or not，we will begin our party on time.

2020_2021学年高考英语语法核心考点复习名词性从句知识点(含参考答案)
高考英语语法核心考点复习：名词性从句知识点概述：名词性从句的功能相当于名词。
根据其在句中充当的成分，可分为：主语从句、宾语从句、表语从句和同位语从句。
主语从句在复合句中做主语的从句叫主语从句。
引导主语从句的连词：that（无意义，所引导的主语从句是完整的），whether （是否），if （是否）（通常只能用于it作形式主语的主语从句），连结代词：who （谁）（主格）, whom （谁）（宾格）, whose（谁的）（所有格）, what （什么，所……的（东西或事情））, which （那个，那些），whoever （无论谁）（主格）, whomever （无论谁）（宾格）, whatever （无论什么）, whichever （无论那个，无论那些），连接副词：when（何时）, where （何地）, how （怎样，如何）, why （为什么）等。
如：That the 2022 Winter Olympic Games will be held in Chengde is known to us all.=It is known to us all that the 2022 Winter Olympic Games will be held in Chengde.=What is known to us all is that the 2022 Winter Olympic Games will be held in Chengde.=As is known to us all, the 2022 Winter Olympic Games will be held in Chengde.众所周知，２０22年冬季奥运会将在承德举行。
That you don’t like him is none of my business.你不喜欢他与我有什么关系呢。
What he said at the meeting astonished everybody present.他在会上的发言是到会的人都感到惊讶。
高考英语二轮复习备考专项冲刺专题13名词性从句(含解析)
专题13 【名词性从句】解题指导·触类旁通寻方法，求策略，掌握“套路”第一步：识别名词性从句的种类1．首先确定主句的谓语动词，确定主句的主谓结构；2．分析从句在主句中所充当的成分，确定从句所属类型：主语从句、宾语从句、表语从句、同位语从句。
第二步：分析从句结构，确定从句引导词确定从句的结构和意义是否完整，结合句意填写适当的连接词。
1．若从句结构完整，用从属连词：陈述事实用that；表示疑问“是否”用if或whether；2．若从句缺少主语、宾语、表语或定语，则考虑用连接代词；3．若从句缺少状语，则用连接副词。
另外，还需注意一些特殊的引导词(if, whether, because, as if等)的用法及that引导同位语从句与定语从句的区别。
技巧1 分析句子成分①缺少主语、宾语、表语：用连接代词what、 who、 whom、 which、 whatever等。
②缺少状语(结合句意判断)：用连接副词where(表地点)、 when(表时间)、 how(表方式)、why(表原因)等。
③不缺成分，句意不完整，缺少“是否”：用if/whether。
④不缺成分且句子意义完整：用that。
技巧2 结合句意和引导词的本义解题有些引导词在句中有很鲜明的意义，如if“是否”；whoever “无论谁”；whatever “无论什么”；whichever “无论哪一个(在范围中选择)”；because“因为”；why “为什么”等。
结合句意和语境，不难解决这类试题。
①that没有词义，也不作任何成分，当从句意义完整，不缺任何成分时用that。
②what在从句中表示“……的(东西)”，在从句中充当主语、宾语、表语、定语等成分。
考点突破·针对提能明考点，攻重难，有效提升考点一、主语从句1．主语从句的引导词引导词作用that, whether, if 只起连接作用，不在从句中作成分，但一般不可省略。
高考英语二轮复习整理---名词性从句讲解
名词性从句在英语中，句子可分为简单句和复合句，复合句即常说的“从句”。
由一个主句和一个（或几个）从句构成的句子叫主从复合句。
在复合句中，我们是根据从句在整个句子中所充当的成分来给复合句命名的。
如：主语从句，宾语从句，定语从句，等等。
所有的复合句中，“主语从句，宾语从句，表语从句，同位语从句”，他们的从句有名词性特征，因此合称为“名词性从句”。
名词性从句的引导词引导词是否在名词性从句中充当成分的情况充当成分：连接代词： what, which, who, whom, whose，whatever, whoever, whichever,不从当成分：连接副词： when, where, why, how, however只起连接的作用：that, if/whether, because（that引导的名词性从句，既不作任何成分，也无意义，只是表明从句是一种陈述语气，起个连接作用；if不能引导表语从句和同位语从句，if引导主语从句时不能置于句首，if引导宾语从句时，只能置于及物动词后，不能置于介词后；because只能引导表语从句）㈠主语从句（用作主语的从句叫做主语从句）1．that从句作主语That引导的主语从句可位于句首直接作主语;也可以位于句末，用it作形式主语;① That we are invited to a concert this evening is a piece of good news for us.②It is obvious that the earth is round.2．whether/if（是否）从句作主语同样可放句首或句末，但放句首只能用whether，不能用if.①Whether we shall go or stay ,is uncertain.②It was not known whether/if he would ask.3． whoever, whichever, whatever, however引导主语从句只能放句首。

(2)后面直接跟or not 时，用whether。 I didn't know whether or not he had arrived in Wuhan. (3)主语从句、表语从句和同位语从句中，只能用whether。 Whether the meeting will be put off has not been decided yet.

高考英语第二轮热点专题复习——名词性从句（最新）考情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，可用作主句的主语、表语、宾语和同位语。
因此，名词性从句分为主语从句、表语从句、宾语从句和同位从句。
引导名词性从句的连接词有：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；连接词：that, whether, if, as if，if (whether), as if虽有词义，但在从句中不担任成分；that 无词义，在从句中不担任成分，有时可省略。
名词性从句重点与难点：一、that从句作主语和宾语时，常用it作形式主语，将从句放在句末e.g. It doesn’t matter so much whether you will come or not.She has seen to it that all the children are well taken care of.二、that引导名词性从句的省略情况1、that引导主语从句、表语从句、同位语从句时，不能省略。
e.g. That he suddenly fell ill last week made us surprised.2、that引导宾语从句时一般可省略，但在以下几种情况中不能省略。
1）当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时不能省略；2）当that 从句与另一名词性从句并列作宾语时不能省略；3）当that作介词宾语时不能省略。
e.g. He judged that, because he was a child, he did not understand wineEveryone knew what happened and that she was worried.The reason lies in that she works harder than the others do.三、名词性从句中的语序名词性从句中一律使用陈序语气。
e.g. He asked how much I paid for the violin.四、名词性从句中的时态呼应在名词性从句中，谓语动词的时态要与主句谓语动词的时态相一致。
e.g. As soon as he comes back, I’ll tell him when you will come and see him.He kept looking at her, wondering whether he had seen her somewhere.Can you make sure where Alice has put the gold ring?五、名词性从句中虚拟语气的使用情况1、在表示“命令、建议、坚持、要求”的名词性从句中，要用“should+动词原形”形式，should可以省略。
e.g. I made a suggestion that he (should) go there at once.I suggested that he (should) go there at once.The suggestion was that he (should) go there at once.2、wish引导的宾语从句中要用虚拟语气，分与现在、过去、将来相反三种情况。
e.g. I wish I were ten years younger.I wish you had posted the letter yesterday.I wish I would try again.3、在句型“It + is/was + adj.+主语从句”中，如果形容词是important, strange, natural, necessary等，从句谓语部分要用“should+动词原形”形式，should可以省略。
e.g. It’s strange that he (should) think so.It is necessary that he (should) go there at once.六、引导同位语从句与定语从句的that的区别同位语从句中的连词that只起连接作用，不充当任何句子成分且不能省略，同位语从句一般放在有具体含义的名词后，用以解释名词的含义或内容；而定语从句中的关系代词that 在从句中充当主语或宾语，在充当宾语时常可省略，定语从句是对先行词的限定和修饰。
e.g. They expressed the hope that they would come to visit China again.The hope she expressed is that they would come to visit China again.七、引导名词性从句的that和what的区别that 引导名词性从句时，在从句中不充当任何句子成分，也没有任何含义，只起连接作用, 且在宾语从句中有时可省略；而what引导名词性从句时，在从句中充当主语、宾语、表语或定语。
e.g. That he said so made us angry .What he said at the meeting made us angry.China is no longer what it used to be.八、疑问词 + ever和no matter + 疑问词的区别1、疑问词 + ever既可引导名词性从句，又可引导让步状语从句。
e.g. Whoever breaks the rule must be punished.Whoever breaks the rule, he must be punished.2、no matter + 疑问词只能引导让步状语从句。
e.g. No matter who breaks the rule, he must be punished.No matter what you do, you must do it well.方法技巧点拨一、学习定语从句应达到的能力要求1、掌握不同的连接词的用法。
2、能够区分四种名词性从句。
3、能够区分名词性从句和定语从句。
二、解题思路高考中考查名词性从句时，经常考查连接词的选用。
解题时应先判断从句的类型，然后判断从句是否缺少成分以及意义是否完整，最后根据引导名词性从句的连词的特点确定特定的连接词。
高考试题分析1. ______ was most important to her, she told me, was her family. （2008山东）A. ItB. ThisC. WhatD. As[解析] C she told me是插入语，可删除。
what引导主语从句，在从句中充当主语。
2. The companies are working together to create ______ they hope will be the best means of transport in the 21st century. （2008北京）A. whichB. thatC. whatD. who[解析] C create后为宾语从句，从句中they hope是插入语，可删除，因为从句中缺少主语，所以用what引导该从句。
3. The last time we had great fun was ______ we were visiting the Water Park.（2008天津）A. whereB. howC. whenD. why[解析] C was后为表语从句，此处when与the last time相呼应，根据句意可排除其他选项。
