名词性从句专题(含答案)
名词性从句
一.相关概念
1.名词: 表示人或事物的名称的词叫名词。
2.名词在句子当中一般可以作什么成分?
名词在句中主要作_____、_____、_____和________。
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。
名主语从句( The Subject Clause) 一个句子相当于一个名词在句中作主语。
词宾语从句( The Object Clause)
从表语从句( The Predicative Clause)
句同位语从句( The Appositive Clause)
判断下列句子属于那种从句：
①. How the prisoner escaped remains a mystery.__________________
②. I wonder whether/if he is fit for the job._________________
③. The problem is who will be equal to the task.________________
④. He had no idea whether we could overcome the present difficulties or not._____
⑤. I shall never forget the years when I lived in the countryside with the farmers.__
答案：1. 主语从句 2. 宾语从句 3. 表语从句 4. 同位语从句 5. 定语从句
4.名词性从句的引导词。
连接词：that , （只起连接作用，不作任何成分，本身没有任何意思）
whether, if（只起连接作用，不作任何成分，意思是“是否”）
as if ,as though （均表示“好像”，“似乎”,只用于表语从句）
连接代词：what, whatever, who, whoever, which, whichever, whom, whomever, whose（起连接作用，作主语，宾语，表语，定语）
连接副词：when, where, why, how, whenever, wherever, however（起连接作用，作状语）
二．主语从句
I划出下列句子的引导词，并判断他们属于哪一类.
1. That he is hard working is known to us.
2. Whether he will come isn’t clear.
3. What we need is water.
4. Whoever comes is welcome.
5. Who will go makes no difference.
6. Which he will choose is obvious.
7. Why dinosaurs died out remains a puzzle.
8. When he w ill give us a lecture hasn’t been decided.
9. How he will go there isn’t important. 10. Wherever you are is my home.
总结:
1).主语从句一律用陈述句语序,即主语在前,谓语在后.
When will he come is not known. 改正：___________________________________
但是what is the matter 和what is wrong 不可改变语序
2).连接词that在从句中无实际意义,起引导作用, 不作任何成分,但不能省略.
He will not come to the meeting this evening is true. 改正：___________________
3).whether可以引导主语从句解释为”是否”,但if不能(若It作形式主语，可用).
4).whoever, whatever, whichever等词可以引导主语从句, 但no matter who, no matter what 等不能,它们只能引导让步状语从句.
II It作为形式主语的主语从句。
当一个句子的主语过长时，为了使句子平衡，我们通常使用it作形式主语，把真正的主语放在其后。
That he is hardworking is known to us.→It is known to us that he is hardworking.
Whether he will go with us isn’t clear.→ __________________________________
III 常见的it作形式主语的句型
It + be + 形容词＋that从句
It is necessary/ important / obvious/likely/possible/certain… that…
Eg：It is obvious that you are wrong.
It + be + -ed分词＋that从句
It is believed that… 人们相信…
It is known to us/all that …. 众所周知…
It has been decided that…… 已经决定……
It is said that…. 据说……
It + be + 名词＋that从句
It is common knowledge that… …是常识
It is a surprise/a fact/a pity/no wonder/a shame…that ….
It + 不及物动词＋that从句
It appears that… 似乎…
It happens that …. 碰巧…
It occurred to me that…… 我突然想起……
IV主语从句中应注意的问题
1.一个句子作主语时，主句的谓语动词应为单数。
Eg Whether he will come depends on the weather.
2. what 引导的句子作主语时，谓语动词的数由句子的内容决定。
What I want is money. What we need are good books
What he said is reasonable. What we will do hasn’t been decided.
3. Where he was born and where he lives now are not clear.
Where and when he was born remains a secret.
两个或两个以上的主从联合做主语，主句谓语动词应为复数。
两个或两个以上的连词引导一个从句，主句谓语动词应为单数。
4. Whether he will come isn’t clear.(不能换成if)
It isn't clear whether he will come . (可以与if进行替换)

b.引导表语从句时；
c.引导从句作介词宾语时；
d.从句后有“or not”时；
e.后接动词不定式时,
f. discuss后只能用whether。
II 表示“建议”“请求”“命令”的词用在名词性从句中，从句的谓语动词要用虚拟语气should +动词原形，should 可以省略掉。
It is suggested that you (should) have a rest.(主语从句)
I suggested that you (should) have a rest.（宾语从句）
My suggestion is that you (should) have a rest.（表语从句）
I give you a suggestion that you (should) have a rest.（同位语从句）
常见词：suggest，advise，order，command，demand，request，require，insist等
III 同位语从句和定语从句的区别
1. 同位语从句用来进一步解释前面名词的内容。
定语从句用来修饰限制前面的名词
E.g. The news that our team has won the final match is encouraging. （从句说明“消息”的内容：我们队取得了决赛胜利。）
The news that you told us is really encouraging.
（从句对“消息”加以限定：是你告诉我们的，而非来自其他渠道。但消息是何内容却不得而知。）2. 同位语从句中的that是连接词，只起连接作用不作任何成分，没有任何意思，但不能省略。定语从句中that是关系代词，在句中作主语，宾语，作宾语时可以省略。
E.g.1) Dad made a promise that he would buy me CD player if I passed the English test. （that 不充当任何成分）
2) Dad made a promise that excited all his children.
（that指代promise，又在从句中充当主语。）
IV. 名词性从句的语序都为陈述语序。
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.
V. 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.
注意：who与whoever的区别
who是“谁”的意思，表示具有疑问，whoever相当于anyone who“无论谁”
He gave whoever came to the door a smile. = He gave any person who came to the door a smile.
比较：He asked me who broke the glass.（正确）他问我是谁打的玻璃。
He asked me whoever broke the glass.（错误）
Whoever goes against law shall be punished.（正确）违法的人将受罚。
Who goes against law shall be punished.（错误）
VI．注意区分it 作形式主语的主语从句与强调句
强调句句型It is/was+被强调部分+that, 去掉It is/was, that，句子仍然成立。
It is natural that they should have different views. 主语从句
It is only lately that he had had a family himself. 强调句
What was it that he wanted? I don’t know what it was that he wanted.
It was in the hotel where he stayed that we discussed the serious problem

名词性从句讲解与辨析
英语语法：名词性从句语法讲解 时间：2016-10-08作者：来源：精品学习网 笔者在此就名词性从句中的几大易错点进行分析，希望对同学们有所帮助。 [关系代词和关系副词的误用] 例1 （2016·全国卷Ⅰ） My uncle is the owner of a restaurant close to that I live. 解析 that→where。本题考查宾语从句，引导词在从句中充当地点状语，所以将that改为where。 例2 （2015·全国卷Ⅱ） As natural architects， the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days. 解析 how。根据语境和空后的形容词thick可知应用how引导宾语从句，此处表示要弄清楚到底土坯房的墙需要“多”厚。故答案为how。 点拨若从句缺少主语、宾语、表语或定语，则考虑用关系代词；若从句缺少时间、地点、原因、方式等状语成分，则使用关系副词 （when/where/why/how）。 [if和whether的误用] 例3 He asked her the question if they can be friends. 解析 if→whether。question后为同位语从句，只能用whether来引导，故而将if改为whether。 例4 It doesn’t matter so much you will come or not. 解析考查主语从句。句意：你来还是不来，这不怎么重要。代词it作形式主语，真正的主语是whether引导的主语从句。 点拨在表达“是否”这一意思时，我们经常会用到whether和if，但以下几种情况只用whether不用if： 1. 在表语从句、主语从句、同位语从句中； 2. 在介词后的宾语从句中。如：It all depends on whether they will

高中名词性从句讲解及练习
名词性从句 主语从句，表语从句，宾语从句和同位语从句在复合句中的作用相当于名词，因此这四种从句统称为名词性从句。这四种从句与主句间不用逗号。 一．名词性从句连接词的选用可分为三类： 1.that在名词性从句中只起连接作用，不充当成分，也没有实际意义。 That he will come is certain. I think that he’ll be all right in a few days. The fact is that I have never been there. The fact that she had not said anything surprised all of us. 2.whether/if 在名词性从句中有“是否”之意，但不充当成分。附Whether/if 区分：在宾语从句中可互换，但介词和discuss后的宾语从句用whether; 其它名词性从句用whether；可以说whether to do 但不能说if to do ;可 说whether / if……or not, whether or not ，不能说if or not.
