2020年高考英语语法必考知识点名词性从句专项练习(pdf)

英语名词性从句知识点复习一、概述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。

It is a fact that English is being accepted as an international language.事实上英语作为国际语言正为世人所接受。

(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。

由一个含疑问意义的连词引起时，必须将该连词放在名词性从句的开头，且该从句语序不能倒装。

What we can't get seems better than what we have. 我们得不到的似乎比我们所拥有的要好。

The photographs will show you what our village looks like. 这些照片将向你展示我们村庄的面貌。

Can you make sure where Alice has put the gold ring? 你能肯定爱丽丝放金戒指的地方吗？No one can be sure what man will look like in a million years.没有人肯定一百万年后人类会是什么样子。

He asked how much I paid for the violin. 他问我花了多少钱买这个小提琴。

三、时态的呼应名词性从句特别是宾语从句中谓语动词的时态要与主句中谓语动词时态要相呼应，主要有下列几种情况：（1）如果主句中的谓语动词是一般现在时态，从句的谓语动词的时态不受主句谓语动词时态的制约。

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。

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。

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。

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。

2020年高考英语一轮考点扫描专题06 名词性从句一、【知识精讲】（一）定义在复合句中,有些从句的作用相当于名词,可以充当主语、表语、宾语或同位语,分别称为主语从句、表语从句、宾语从句和同位语从句。

这些从句统称为名词性从句。

（二）名词性从句的分类和特征What he said surprises me.（主语从句）I’m surprised at what he said. （宾语从句）That is what he said.（表语从句）He told us the news that he was leaving for America. （同位语从句）注意：①名从在什么位置就叫什么从句；②名从中用陈述语序,主谓不能颠倒。

“ Where do you live?” he asked me. ———He asked me where I lived.（三）引导名词性从句的连接词1. 连接词:that, if, whether —在名词性从句中不充当成分。

that无词义, if/whether“是否”2. 连接代词: what, which, who, whom, whose/whatever, whichever, whoever, whomever—在名从句中充当主语、宾语、表语、定语3. 连接副词: when, where, why, how/whenever, wherever, however —在名从中充当状语引导名从的连接词选择的关键：名从中缺失什么成分主语从句(Subject Clause)（一）概念在复合句中充当主语的从句, 常常放在主句谓语动词之前。

That we have been invited to the concert is good news to us.Whether he will come or not is not known yet.What we need is knowledge.When we shall hold our art festival has not been decided.Whoever breaks the law deserves a fine.What confused me was why he failed to recognize me at first sight.（二）形式主语it为了避免句子头重脚轻,常用形式主语it代替主语从句放于句首,而把主语从句置于句末。

专题十四名词性从句重难点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，可作主句的主语、宾语、表语和同位语。

因此，名词性从句可分为主语从句、表语从句、宾语从句和同位语从句（见下表）。

主语从句作主语，用that, whether, if, what(=the thing that)等连接词引导。

宾语从句作宾语，用that（可省略）, whether（or not）, if, what(=the thing which)等连接词引导。

表语从句用that（一般不省略）, whether, what(=the thing which)等连接词引导。

同位语从句用that（常用在news, thought, idea, plan, suggestion, fact等词后），whether等连接词引导。

一、主语从句主语从句是在复合句中充当主语的从句，通常放在主语谓语动词之前或由形式主语it代替，而本身放在句子末尾。

如：Who will go is not important. 谁将去不是重要的。

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每一部分进行强调，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。

如：It is a pity that you didn’t go to see the film. (主语从句) 你没去看电影真是遗憾。

It is in the morning that the murder took place. （强调句）谋杀案发生的时间是在早晨。

2. 用it作形式主语的结构句型例句1 It is+名词+主语从句It is a fact that…事实是……/ It is an honor that…非常荣幸……/ It iscommon knowledge that………是常识2 It is+形容词+主语从句It is natural that………很自然/ It is strange that…奇怪的是……（此句型后面常接虚拟语气should+动词原形）3 It+不及物动词+主语从句It seems that…似乎……/ It happened that…碰巧……/ It appears that…似乎……4 It is/has been+过去分词+It is reported that…据报道……/ It has been proved that…据证实……/ It is主语从句said that…据说……/ It is believed that 据认为/一般人都认为……2. 主语从句不可位于句首的五种情况说明例句1 if引导的主语从句不可位于复合句句首Whether he will come or not in unknown. (正)If he will come or not is unknown. (误)2 It is said/reported…结构中的主语从句不可提前It is said that Jiang will visit our school next week. (正) Jiang will visit our school next week is said. (误)3 It happens/occurs…结构中的主语从句不可提前It occurred to him that he failed in the examination. (正) That he failed in the examination occurred to him. (误)4 It doesn’t matter how/whether…结构中的主语从句不可提前It doesn’t matter whether he is wrong or not. (正) Whether he is wrong or not doesn’t matter. (误)5 含主语从句的复合句是疑问句时，主语从句不可提前Isn’t likely that it will rain in the evening? (正) Is that it will rain in the evening likely? (误)二、宾语从句宾语从句是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）或介词之后。

2020高考英语语法专题汇总（三）：名词性从句(附例题及电子版)在复合句中起名词作用的从句叫作名词性从句。

包括主语从句、宾语从句、表语从句和同位语从句。

注：由于名词性从句在句中不同的句法功能（即名词性从句在复合句中，能充当主语、宾语、表语、同位语等。

）相应地，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主语从句主语从句可直接放在句首，也可用形式主语it代替，而将主语从句后置。

•that引导的主语从句1)that引导的主语从句置于句首（that此时在从句中不充当任何成分，无含义，只起连接作用，不能省略）That the earth moves around the sun is known to all.注：从句作主语，谓语动词用单数形式。

2)在that引导的主语从句中，常用it作形式主语，that引导的真正的主语从句后置，常见的此类句型有：①It+系动词+形容词+that从句。

常用于这种结构的形容词有：It is likely that he can’t come to the meeting.It is obvious that you have made a big mistake.注：It isnecessary/important/surprising/strange/unthin kable/unbelievable/incredible that+主语(should)+动词原形+其它。

例：It is necessary that a college student (should) master one or two foreign languages.It is strange that you (should) trust Jane.②It+系动词+名词+that从句。

常用于这种结构的名词有：It is a pity that you didn’t attend the lecture yesterday.It is no wonder that you’ve achieved so much success.③It+ be+过去分词+that从句。

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主句中作主语的句子，它由连接词引导，通常位于谓语动词之前。

1. 连词：在从句中不充当任何成分，常用见的引导主语从句的连词有三个，即that, whether和if.That he got the first prize excited him much. 他获得一等奖一事使他非常兴奋。

Whether you can succeed or not depends on how hard you work at it. 你能否功取决于你努力的程度。

注意：whether引导的主语从句常用置于句首，表示“是否”之意；if引导主语从句时不置于句首。

2. 连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语，有具体意义且不能省略。

常见的连接代词有who, whom, whose, what, which, whoever, whomever, whatever, whichever.What we should do with the problem is undecided. 我们如何处理这上问题还未作出决定。

3. 连接副词：在从句中起副的作用，常作从句的状语，表示时间、地点、原因、方式等。

常见的连接副词有when, where, how, why, whenever, wherever, however等。

How they will solve the serious problem has not been decided. 他们将如何解决这个严重的问题还没有决定。

Why he did that wasn’t quite clear. 他为什么做那件事还不十分清楚。
