(最新实用)2020年高考英语语法专项突破训练专题15-名词性从句

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。

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。

（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.that引导主语从句时，不能省略。

e.g. That he suddenly fell ill last week made us surprised.3.用it作形式主语，主语从句放在句末。

It+系动词+形容词+that从句. necessary,right,likely,wrong,important,certain,clear...It+系动词+名词+that从句. a pity, a shame, a fact,no wonder...It+be +动词ed+that从句. said,told,reported,suggested,considered....It+特殊动词+that从句. seem,turn out,appear,matter...e.g. It doesn’t matter so much whether you will come or not.4.whether引导的主语从句可放句首，而if引导的主语从句不能放句首，只能放句末。

Whether the worked can be completed on time is doubtful.It is doubtful whether/if the work can be completed.（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.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。

2020全国高考汇编之名词性从句一（2020北京卷）30. The best moment for the football star was _______ he scored the winning goal.A. whereB. whenC. howD. why【考点】考察名词性从句【答案】B【解析】本题属于名词性从句中的表语从句。

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。

【解析】句义：我恐怕他比起来一个实践家更是一个空谈家，那就是他一事无成的原因。

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。
