高考英语易错语法点30题专题10 名词性从句(解析版)

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”。

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。

《2017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。

2015年高考全国卷Ⅰ没有考查名词性从句。

2016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。

2017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 know what 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, whose, which, what,whether,if疑问副词when, where ,why,how,缩合连接词whatever,whoever,whomever,whichever,h owever, whenever,wherever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。

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。

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。

名词在从句中主要做主语宾语表语同位语
名词性从句 : 主语从句, 表语从句, 宾语从句, 同位语从句
起名词性作用的从句，叫名词性从句。换言之，在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语部分，换由一个句子来充当，这样的句子就是名词性从句。
基本结构：简单句+并列连词+简单句。
并列连词通常为：and, but, or, so，not only…but also, neither…nor; as well as 等。
并列句：简单句+并列连词+简单句

高考英语语法总复习名词性从句

名词性从句
• 一、名词性从句的种类
• 名词性从句是起名词作用的从句，包括主语从句、宾语从句、表语从句、同位语从句。
请思考：
1、English is very useful for us . 2、We need to master English well. 3、The subject I am interested in is English. 4、He want to learn the language , English .
• 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。 • It is evident that lung cancer is closely related to smoking.
注意：
1. 在口语或非正式问题中，引导宾语从句的that常省略，但在下面情况下，that 一般不省略（1）当一个句子有两个或多个并列的宾语从句时，除第一个从句的that外，都不可省略。 He told me (that) the power would be cut off and that I should get out. （2）形式宾语it后的that及介词后面的that不能省略。 2. 如果主句主语是第一人称，谓语动词是think ,consider, believe, suppose, expect, fancy, guess, imagine等，后面的宾语从句含有否定意义，否定转移。 I don't think this dress fits you well. 我认为这件衣服不适合你。

2015年高考语法专题攻克之10名词性从句

高考语法专题攻克Ⅹ、名词性从句一、名词性从句引导词的区别引导词的选择最可靠的办法就是根据它们的意思和从句所缺的成分进行选择。

如：who意为“谁”，在从句中可以作主语、表语或宾语；whom意为“谁”，在从句中作宾语，并且一般可以用who来取代，但在介词后面时只能用whom；why意为“为什么”，在从句中作原因状语；which意为“哪一个”，在从句中作定语；where意为“哪里”，在从句中作地点状语；how意为“怎样，多么……”，在从句中用来作状语；whose意为“谁的”，在从句中作定语；when意为“什么时候”，在从句中作时间状语。

1、引导词what与that的用法区别两者均可引导主语从句、表语从句和宾语从句。

区别在于what除了起连接作用外，还在句中用作主语、宾语或表语，表示“……的人/ 物”或“所……的”；而that仅起连接作用，本身没有实际意义，在从句中也不充当任何句子。

一般在从句中不缺少主语、表语或宾语时使用，引导宾语从句时有时可以省略。

引导主语从句时，常用it作形式主语，而将that引导的主语从句放在句子的后面，that不可省。

如：○1What we need at present is patience.（主语从句，what在从句中作宾语，不可省略）○2What is needed for you is determination and courage.（主语从句，what在从句中作主语，不可省略）○3I didn’t know (that) he was late for school again this morning.（宾语从句，that在从句中不作成分，可以省略）试比较：What he said made me angry.That he said so made me angry.【分析】两个句子都是主语从句，第一个句子中what作said的宾语；第二个句子中that不作成分，但不可省略。

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。

语法：名词性从句

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，名词性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。

1.Owing to the natural environment, many people feel that New Zealand is perfect for outdoor activities. （宾语从句）2. The idea that red represents bravery and blood is widely believed. （同位语从句）3.

【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。

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。

语法复习10：名词性从句

语法复习10：名词性从句在句子中起名词作用的从句叫名词性从句(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、同位语等，因此根据它在句中不同的语法功能，名词性从句可分为主语从句、宾语从句、表语从句和同位语从句。

其关联词有连接词that，if，whether；连接代词who，whom，whose，what，which，whoever，whomever，whatever，whichever；连接副词when，where，why，how等。

一．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。

【完成例句】根据句意选词填空(that, if, whether, why, when, what)(1) That he will succeed is certain.(2) Whether he will go there is not known.(3) What he said is not true.(4) When the meeting will be held has not been decided yet.【结论】①that－从句，从句为一个句意完整的陈述句，没有具体意义，不充当句子成分，只起标志性作用，但that 不能省略。

②whether －从句，从句来源于一般疑问句，whether不能省略，意为“是否”，不能用if替换。

③特殊疑问词－从句，从句来源于特殊疑问句，特殊疑问词不能省略，意思为特殊疑问词本来的意思，在从句中充当句子成分。

What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
