【高考专题】高考必考语法精讲精练专题10：名词性从句(含解析)

高中英语名词性从句知识讲解以及练习题附答案一、名词性从句概述名词性从句是一种充当名词作用的从句，通常在主句中作主语、宾语、表语或同位语。

它通常由引导词（如that, whether, if, who, whom, whose, which, what等）引导，并且从句中含有一个主语和谓语。

名词性从句的种类有很多，包括主语从句、宾语从句、表语从句和同位语从句等。

下面我们将逐一介绍这些从句。

二、主语从句主语从句作为一个名词，通常位于句首，是一个句子，主要作用是作为主句的主语。

引导主语从句的词：What (什么)；Whether (是否)；If (是否)；That (那个)。

例句：What he said is true. (他说的是真的。

)Whether it will rain tomorrow is uncertain. (明天是否会下雨还不确定。

)If you go, I will go too. (如果你走，我也跟着走。

)That he is coming is good news. (他来的消息是好消息。

)注意：主语从句的谓语动词通常要用单数形式。

What引导的主语从句通常用来表示“事物”的概念。

三、宾语从句宾语从句是一个名词，通常位于主句的动词后面，作为主句的宾语。

它可以由常见的宾语从句引导词引导，例如whether, if, that, who, whom, whose, what, when, where, how等。

引导宾语从句的词：Whether (是否)；If (是否)；That (那个)；Who (谁)；Whom (谁)；Whose (谁的)；What (什么)；When (何时)；Where (何处)；How (如何)。

例句：I know that he is coming. (我知道他要来。

)I wonder if he is telling the truth. (我想知道他是否说了真话。

专题十名词性从句A组三年模拟精选(2015～2013)(改编)1.(2015·辽宁鞍山联考)One day，he came up with an idea he would pluckup all of his crop a few inches.解析考查同位语从句的引导词。

因后面是一个完整的句子，且该句是说明空格前面an idea的具体内容，所以是同位语从句。

从句结构完整，故要用that引导。

答案that2.(2015·广西南宁二中月考) is important is that we let others know wecare about them.解析考查主语从句的引导词。

根据句子结构可知，系动词is前的句子缺少主语，表示“重要的事情”要用what。

答案What3.(2015·内蒙古师大附中月考)Over the next several months，my professor taught meone story was so much better than the other.解析考查宾语从句的引导词。

教授教给我的是为什么一个故事比另一个更好。

根据句意可知此处要用why引导宾语从句。

答案why4.(2015·河南开封四模)A study found girls who ate five or more familymeals a week had a much healthier relationship with food in later life.解析考查宾语从句的引导词。

谓语动词found后为宾语从句，宾语从句中不缺少成分，故要用that引导。

答案that5.(2015·四川成都七中二诊)Perhaps my mother had told me was deeplyrooted in my mind.解析考查主语从句的引导词。

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。

高考语法复习10名词性从句【走进高考】1.【2018·北京】Without his support, we wouldn’t be _________ we are now.A. howB. whenC. whereD. why【答案】C【解析】考查名词性从句。

句意：没有他的支持，我们是不会在现在这个位置的。

how表方式，when表时间，where表地点，why表原因。

“_________ we are now”是表语从句，结合句子的意思可知，该处指我们所处的位置，故该从句应用where引导。

C选项正确。

2.【2018·北京】This is _________ my father has taught me—to always face difficulties and hope for the best.A. howB. whichC. thatD. what【答案】D【解析】考查名词性从句。

句意：这是我父亲教我的——总是要面对困难，抱最大的希望。

"________ my father has taught me"是表语从句，该空在从句做teach的宾语，且表示“父亲教我的道理”，故该从句应用what引导。

D选项正确。

引导名词性从句时，how表示方式，意为“如何”；which意为“哪一个”，that在此只起引导从句的作用，不做成分。

3.【2018·天津】The gold medal will be awarded to ___________ wins the first place in the bicycle race.A. whomeverB. whereverC. whoeverD. whatever【答案】C【解析】考查名词性从句连接词。

句意：无论谁获得自行车比赛第一名，金牌将授予他。

分析句子可知，宾语从句中缺少主语，故用whoever，表示“任何人，无论谁”。

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。

语法专题二：名词性从句1. 名词性从句的基本概念：1) 主语从句：在句中充当主语；亦可用it作形式主语，主语从句置于句末。

2) 宾语从句：在句中充当及物动词或介词的宾语；亦可用it作形式宾语，宾语从句置于句末。

3) 表语从句：在句中充当系动词的表语。

4) 同位语从句：常置于fact, idea, news, promise, doubt, suggestion, possibility, belief等表示有内容的名词后，起解释、说明作用。

2. 注意：1) 名词性从句要用陈述句语序。

2) 名词性从句中缺少主语、表语、宾语时：常用what 导，亦可用which表示选择，用who/whom/whoever指人。

缺少状语：用where（表地点）, when（表时间）, how（表方式）, why（表原因）。

3) 如不缺成份：主语从句、同位语从句用that引导，不能省略；表从、单个动词宾从可省略引导词that；介词宾从、第二个宾从，引导词that一般不省略；it作形式主语或宾语时，引导实际主从或宾从，一般that不省略；当主从、宾从本身为复合句时，引导词that不省略。

如：He told us sadly that what he had done secretly was dis covered by his parents.4) 含宾从的复合句中，主句和从句的时态保持一致，但如果从句中表示是客观现象，虽然主句是过去时态，从句仍用一般现在时。

5) 主语从句做主语，谓语动词用单数；如果由and 连接两个或两个以上的主语从句做主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。

6) 当主句是I/We think（或suppose, expect, believe, imagine, guess）时，其后的宾语从句如果是否定的，常常把否定词not从从句中移到主句中。

7) 只能用whether，不能用if表示“是否”的情况如下：(1) 在表语从句和同位语从句中；(2) 在主语从句中，如果用it做形式主语，whether和if都能引导主语从句，否则，只能用whether(3) 在介词之后；(4) 后面直接跟动词不定式；(5) 与or not连用；(6) 引导让步状语从句，只能用whether。

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。

名词性从句是一种具有名词功能的非独立分句。

具体用法见下表：主语从句大多数主语从句都可以用it作形式主语而把主语从句置于句尾。

(what引导的主语从句表示“……的东西”时，一般不用it作形式主语；whatever, whoever, whichever一般也不用it作形式主语。

)►It makes no difference where we shall have the meeting.我们在哪开会无所谓。

【注意】(1)常见的it替代that引导的主语从句的句式主要有以下几种：①It＋系动词＋形容词(necessary/right/likely/important/certain...)＋that从句②It＋be＋名词(短语)(a pity/a shame/good news/a fact/an honour...)＋that从句③It＋be＋过去分词(said/told/heard/reported/decided/suggested...)＋that从句④It＋特殊动词(seem/appear/happen/matter)＋that从句(2)在“It is necessary/important/natural...＋that从句”的结构中，从句谓语常用“(should ＋)动词原形”。

宾语从句1．动词find, feel, think, consider, make, believe等后有that引导的宾语从句作宾语补足语时，则常用it作形式宾语而将that宾语从句后置。

►I think it necessary that we take plenty of boiled water every day.我认为每天摄入足量的白开水很有必要。

2．有些动词(短语)不能直接跟宾语从句，需要借助形式宾语it。

常见的有hate, enjoy, like, dislike, love, appreciate, see to等。

专题十名词性从句【高频考点解读】考查名词性从句中引导词的选用，区分what，that，wh-ever，whether，if等连接代词和连接副词的语义功能和语法功能。

尤其是把名词性从句与定语从句放在一起进行综合考查，增加了试题的难度。

【热点题型】题型一考查主语从句及连接词的辨析例1、It is by no means clear the president can do to end the strike.A．how B．which C．that D．what【提分秘籍】that与what的区分1．引导名词性从句时，that没有意义，在从句中不作任何成分。

因此当从句意义完整，不缺任何成分时，往往用that，that引导主语从句、同位语从句、表语从句时不行省略。

2．what引导名词性从句时，意为“什么”(有时候可以不译出来)在从句中作主语、表语或宾语，从不行省略。

【举一反三】It suddenly occurred to him he had left his keys in the office.A．whether B．whereC．which D．that【热点题型】题型二考查宾语从句及连接词的辨析例2、We promise attends the party a chance to have a photo taken with the movie star.A．who B．whomC．whoever D．whomever 【提分秘籍】“疑问词”与“疑问词＋ever”的区分“疑问词＋ever”可以引导名词性从句，含有“无论……”之意，用法与“疑问词”一样，只是语气比疑问词本身的语气猛烈得多。

“疑问词＋ever”与“no matter＋疑问词”的区分①“疑问词＋ever”引导名词性从句时，whoever＝anyone who，whatever＝anything that等。

如：Whoever(＝Anyone who)comes is welcome.②“no matter＋疑问词”只能用来引导状语从句。

（直击高考）2013高考英语语法重难点系列专题10 名词性从句考点在句子中起名词作用的句子叫名词性从句(Noun Clauses），引导名词性从句的词叫连词。

名词性从句又分别称为: 主语从句、宾语从句、表语从句、同位语从句主语从句：是在复合句中充当主语的从句，常放在谓语动词之前或者用形式主语it代替，将其本身放在句尾。

例如：1. That he came here just now has been proved.他刚才来的这里得到了证实。

解析：That he came here just now在谓语has been proved的前面，所以是主语从句。

2. It’s true that we are going next week.我们下星期走是真的。

解析：真正的主语是 that we are going next week，前面的i t是形式主语。

宾语从句：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）和介词之后。

例如：1. We all know what he is.我们都知道他是干什么的。

解析：what he is作及物动词know的宾语从句。

2. His worry is about whether he can succeed.他的担忧是关于他是否能成功。

解析：whether he can succeed作介词about的宾语从句。

表语从句：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+联系动词+表语从句例如：1. His question is where he can buy a house.他的问题是他能在哪里买房子。

解析：where he can buy a house是联系动词is后面的表语从句。

2. This is why we can’t get their support.这就是我们得不到他们支持的原因。

解析:why we can’t get their support是联系动词is后面的表语从句。

考点巩固卷10 名词性从句最新高考真题1.（2024·新高考II卷·语法填空）If most of their customers are happy to buy larger quantities, that’s ________ they’ll promote. But that leaves the solo (单独) customers out of pocket and disappointed.【答案】what【解析】考查名词性从句。

句意：假如他们的大多数客户都乐意大量购买，那他们就会推广。

在表语从句中缺少宾语，且是指事物，所以应用连接代词what。

故填what。

2.（2023·新高考II卷·语法填空）This is ________ they need an English trainer.【答案】why【解析】考查表语从句。

句意：这就是他们需要英语培训师的缘由。

分析句子结构可知，空处引导表语从句，从句中结构完整，应当用连接副词连接，前文提到需要培训师的缘由，此处是表达“这就是他们需要英语培训师的缘由”之意，应用why引导表语从句。

故填why。

3.(2022·新高考II卷·语法填空)Cobb, for her party, started to ask conference organizers who invited her to speak ______ she could do so remotely; about three-quarters of the time, they agreed.【答案】whether或if【解析】考查宾语从句。

句意：对于她的出席，Cobb开头询问邀请她的组织者是否可以远程进行。

明显ask后面消灭了一个宾语从句，宾语从句句意不完整，whether/if“是否”符合语境，故填whether或if。

备战2021年高考英语经典小题考前必刷10.核心语法之名词性从句【刷重点】重点一宾语从句★★★★★1.引导宾语从句的连接词从属连词that、whether、if；连接代词what、who、whose、whatever、whichever、whoever等；连接副词when、where、why、how等；从句用陈述语序。

·I truly believe that beauty comes from within.我确信美来自内在。

·What we should take with us depends on where we'll stay.我们需要随身带什么东西，取决于我们将在什么地方停留。

2．it做形式宾语的宾语从句(1)一些动词后的宾语从句有宾语补足语时，则需要用it做形式宾语，而将that引导的宾语从句后置。

常见的这类动词有：find、feel、think、consider、believe、guess、suppose、make等。

·He has made it clear that the meeting will not be postponed.他清楚地表明会议不会被推迟。

(2)动词hate、like、dislike、appreciate、enjoy等表示“喜欢”“厌恶”等的动词以及一些动词短语see to、depend on、rely on等，常用it做形式宾语，而将宾语从句后置。

·I shall see to it that he will be taken good care of when you are absent.你不在的时候，我会确保把他照顾好。

专题10 名词性从句距离高考还有一段时间，不少有经验的老师都会提醒考生，愈是临近高考，能否咬紧牙关、学会自我调节，态度是否主动积极，安排是否科学合理，能不能保持良好的心态、以饱满的情绪迎接挑战，其效果往往大不一样。

以下是本人从事10多年教学经验总结出的以下学习资料，希望可以帮助大家提高答题的正确率，希望对你有所帮助，有志者事竟成！养成良好的答题习惯，是决定高考英语成败的决定性因素之一。

做题前，要认真阅读题目要求、题干和选项，并对答案内容作出合理预测;答题时，切忌跟着感觉走，最好按照题目序号来做，不会的或存在疑问的，要做好标记，要善于发现，找到题目的题眼所在，规范答题，书写工整;答题完毕时，要认真检查，查漏补缺，纠正错误。

总之，在最后的复习阶段，学生们不要加大练习量。

在这个时候，学生要尽快找到适合自己的答题方式，最重要的是以平常心去面对考试。

英语最后的复习要树立信心，考试的时候遇到难题要想“别人也难”，遇到容易的则要想“细心审题”。

越到最后，考生越要回归基础，单词最好再梳理一遍，这样有利于提高阅读理解的效率。

高考必考语法精讲精练专题十：名词性从句（含解析）高考必考语法精讲精练语法专题十：名词性从句名词性从句是比较重要的语法项目。

《2021年普通高等学校招生全国统一考试大纲》附录语法项目表中对名词性从句列了四项：主语从句、宾语从句、表语从句和同位语从句。

全国卷新课标Ⅰ对名词性从句的考查一般在语法填空和短文改错中，主要考查从句引导词的用法。

2021年高考全国卷Ⅰ没有考查名词性从句。

2021年高考全国卷Ⅰ第71题（短文改错）考查了宾语从句的引导词，My uncle is the owner of a restaurant close to that I live.本句中须将that改为where。

2021年高考全国卷Ⅰ没有考查了名词性从句。

在复合句中起名词作用的从句叫做名词性从句。

名词可以充当句子的主语、宾语、表语和同位语，因此，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。

①What was most important to her was her family.(主语从句) ②I don’t knowwhat you want to say.(宾语从句)③The good news is that we have won the game.(表语从句) ④The news that we have won the game is true.(同位语从句) 引导名词性从句的关联词：从属连词that, because 疑问代词 who, whom, what,whether,if whose, which, 疑问副词when, where ,why,how, 缩合连接whatever,whoever,whomever,whichever,however, whenever,wherever 词关联短语 as if ,as though 注意：连词that在引导名词性从句时无词义，不充当句子成分，只起连接作用，在主语从句、表语从句和同位语从句中不能省略，在引导宾语从句时，口语或非正式的文体中常被省去；疑问代词、疑问副词、缩合连接词以及关联短语在句中既保留自己的含义又起连接作用，在从句中充当成分。

v1.0 可编辑可修改1高考英语名词性从句讲解【考情剖析】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。

引导名词性从句的衔接词有：衔接代词：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；衔接副词：when, where, why, how ，有词义，在从句中担任成分，作状语；衔接词：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。

今后对名词性从句的考查仍将集中在关联词的选用上，特别石堆what 引导的名词性从句的考查。

名词性从句与其他从句的混合考查将在今后高考中占据一席之地。

易混句型的辨析，比如it 作方式主语，主语从句后置的句型与强调句型的辨析将仍作为高考考查的重点。

【知识点归纳】名词性从句的用法在句子中起名词作用的句子叫名词从句 (Noun Clauses ）。

名词从句的功用相当于名词词组, 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一样的语法功用，名词从句又可区分称为主语从句、宾语从句、表语从句和同位语从句。

一、引导名词性从句的衔接词引导名词性从句的衔接词可分为三类：连词：that （无任何词意）；whether, if （均表示“能不能”标明从句内容的不确定性）；as if ,as though （均表示“似乎”，“似乎”）。

以上在从句中均不充任任何成分衔接代词：what, whatever, who, whoever, whom, whose, which. Whichever, whomever 衔接副词：when, where, how, why 不可省略的连词： 1. 介词后的连词2. 引导主语从句和同位语从句的连词不可省略。

专题十名词性从句1.【2021·湖南】26.You have to know ________ you're going if you are to plan the best way of getting there.A. whatB. thatC. whereD. who【答案】C【考点定位】考查宾语从句。

【名师点睛】推断是什么句子最关键，这个句子是由know引导的宾语从句，宾语从句的连接词有连接代词和连接副词。

由于从句部分缺少状语成分，答案就出来了。

正确解答该题需要理解句意以及留意上下文（you're going if you are to plan the best way of getting there.）的表达。

2.【2021·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：我很信任秀丽源自于内心! 本题考查宾语从句。

从句部分不缺少任何成分，因此用that起到连接作用，也可以省略。

从句部分不缺少任何成分，因此用that起到连接作用，也可以省略。

故选A。

【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，要留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。

当一个句子充当宾语时，这个句子就称之为宾语从句。

一般状况下，宾语从句可作谓语的宾语，也可做主语的宾语。

依据所选空在句中所作的成分来推断出是何种名词性从句。

3.【2021·安徽】25.A ship in harbor is safe, but that’s not ______ ships are built for.A. whatB. whomC. whyD. when【答案】A【解析】试题分析：句意：船停放在海港里是很平安的，但这并非建筑船的目的。

考点10 名词性从句（解析版）【命题趋势】名词性从句是高考的必考点，它在句中可以作主语、宾语、表语和同位语。

单项填空题对名词性从句的考查集中在引导词上，其中连接代词that与what，if与whether是考查的重点。

解决名词性从句的问题的关键是：一、通过从句的位置辨别从句的类型；二、分析从句，看看从句中所缺少的句子成分和句意，最终确定选用合适的连接词。

【重要考向】一、主语从句；二、宾语从句；三、表语从句；四、同位语从句；考向一【2021全国新高考卷Ⅰ语法填空】Going to Mount Huangshan reminds me of the popular Beatles’ song “The Long and Winding Road”. ______is so breathtaking about the experience is the out-of-this-world scenes.【参考答案】考查主语从句。

句意：这次经历的惊人之处在于这世界之外的景色。

此处是主语从句，从句缺乏主语，应用what引导，指代“经历的事情”。

故填What。

1．引导主语从句的连接词：连词that，whether等；连接代词what，who，whose，whatever，whichever，whoever等；连接副词when，where，why，how等。

2．主语从句一般放在句首，但常用it作形式主语，而将主语从句移到句子的末尾。

常见的句型有：(1)It＋be＋形容词(necessary/likely/important/certain等)＋that从句(2)It＋be＋名词(短语)(a pity/a shame/no wonder等)＋that从句(3)It＋be＋过去分词(said/told/reported等)＋that从句(4)It＋不及物动词(seem,appear,happen,matter等)＋that从句Whatever she says will not make any difference to our arrangements.无论她说什么都不会对我们的安排有影响。

名词性从句名词性从句的考查要点：(1) What ,that 引导名词性从句的区别;(2) Whether ,if 引导名词性从句的区别;(3) 同位语从句和定语从句的区别；一、 名词性从句概述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、和同位语，因此根据它在句中充当不同的语法功能，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。

二、名词性从句比较请注意1、名词性从句中的that 省略情况：动词后的宾语从句和表语从句中的that 可以省略。

2、No matter +wh-开头的词如no matter what 等只能连接让步状语从句。

而wh-开头的词+ever 如whatever 等既能连接让步状语从句，也能连接名词性从句。

解题步骤和原则：分析复合句结构，找出从句，确定名词性从句中的哪一类。

分析从句，结合上表中各个连接词的特点，缺什么补什么。
