名词性从句讲解
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。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面 1.考查名词性从句的语序问题
2.考查引导词that与what的区别
3.考查it在名词性从句中作形式主语或形式宾语的用法 4.考查whether与if的区别
5.考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别
6.考查名词性从句的虚拟语气问题 语法要点剖析
一、名词性从句
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。
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 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： What he wants to tell us is not clear.他要跟我们说什么，还不清楚。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。常用句型如下：（1）It + be + 名词 + that从句
（2）It + be + 形容词 + that从句（3）It + be + 动词的过去分词 + that从句
（4）It + 不及物动词 + that 从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should)+do”，常用的句型有：
It is necessary(important, natural, strange, etc.)that „
It is a pity(a shame, no wonder, etc.)that„
It is suggested(requested, proposed, desired, etc.)that„ 2.宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。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。例如：
He has told me that he will go to Shanghai tomorrow.他已经告诉我他明天要去上海。We must never think(that)we are good in everything while others are good in nothing.我们决不能认为自己什么都好，别人什么都不好。
注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如： I insist that she(should)do her work alone.我坚持要她自己工作。
The commander ordered that troops(should)set off at once.司令员命令部队马上出发。2.用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。
例如： I want to know what he has told you.我想知道他告诉了你什么。
She always thinks of how she can work well.她总是在想怎样能把工作做好。She will give whoever needs help a warm support.凡需要帮助的人，她都会给予热情的支持。
3.用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：
a.引导主语从句并在句首时；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。
例如： Whether there is life on the moon is an interesting question.月球上有没有生命是个有趣的问题。
Everything depends on whether we have enough money.一切要看我们是否有足够的钱。4.注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用 不同时态。
例如： he studies English every day.（从句用一般现在时）he studied English last term.（从句用一般过去时）
I know(that)he will study English next year.（从句用一般将来时）he has studied English since 1998.（从句用现在完成时）
当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：The teacher told us that Tom had left us for America．
5.think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。
例如： We don’t think you are here.我们认为你不在这。I don’t believe he will do so.我相信他不会这样做。3.表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。例如： The fact is that we have lost the game.事实是我们已经输了这场比赛。
That is why he didn’t come to the meeting.那就是他为什么不到会的原因。It looks as if it is going to rain.看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如： The reason why he was late was that he missed the train by one minute this morning 4.同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：
The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。I have no idea when he will come back home.我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill.他想到可能玛丽生病了。同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）
（二）名词性从句的一般引导词
1.连接词 that 引导名词性从句时，只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如：
I hope(that)you enjoy your holiday.希望你假期过得好。That he likes you is very obvious.很显然他喜欢你。2.连接词 whether 引导名词性从句也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成 if，但引导其他名词性从句时不能换成 if。如：
He asked whether [if] I would show him the way.他问我是否可以给他带路。
Whether it will do us harm remains to be seen.是否对我们有害还要看一看。(引导主语从句，不能用 if 代替 whether)3.连接代词 who(m), whose, which, what 等引导名词性从句时，均有各自的意义，在从句中作主语、宾语、定语等。如：
That’s why she wanted to leave.这就是她想离开的原因。When we arrive doesn't matter.什么时候到没有关系。Tell me which one you like best.告诉我你最喜欢哪一个。
4.连接副词 when, where, why, how 等引导名词性从句，也各自有自己的意义，在从句中作状语。如： The question is how we should carry out the plan.问题是怎样执行这个计划。
When she’ll be back depends much on the weather.她什么时候回来在很大程度上要看天气。Why he did it will remain a puzzle forever.他为什么这样做将永远是一个谜。
（三）名词性从句的重要引导词
1.what 用于引导名词性从句是一个十分重要的引导词，它可引导主语从句、宾语从句和表语从句，但不用于引导同位语从句。它引导的名词性从句有两个意思是：一是表示“什么”，带有疑问意味；二是表示“„所„的”，相当于一个先行词后接一个关系代词。如：
I don’t know what you want.我不知道你想要什么。
I don’t know what you want is this.我不知道你所想要的是这个。2.what 引导名词性从句时可用作限定词，其后修饰名词。如： I gave him what books I had.我把我所有的书都给他了。
He gave me what money he had about him.他把身边带有的钱全给了我。
注：what 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词，并且后接不可数名词时，有时可有little修饰，两者的区别是：what+不可数名词=所有的都，what little+不可数名词=虽少但全部。如：
What friends she has are out of the country.她有的那些朋友全在国外。We gave him what(little)help we could.我们给了他我们力所能及的帮助。
3.whoever, whatever, whichever 等也可引导名词性从句，其意分别为“所„的一切事或东西”、“任何„的人”、““„的任可人或物”等。如：
Whoever wants the book may have it.任何人要这书都可拿去。I’ll do whatever I can to help him.我们将尽我们所能来挽救他。Buy whichever is cheapest.买最便宜的。注意以下受汉语意思影响而弄错的句子： 任何人来都欢迎。
误：Who comes will be welcome./ Anyone comes will be welcome.正：Whoever comes will be welcome./ Anyone who comes will be welcome.另外，它们也可引导让步状语从句，其意为“无论„”、“不管„”，其意相当于 no matter who [what, which]。如：
Whatever happens, you must be calm.不管发生什么情况，你都必须镇静。(whatever = no matter what)He won't eat you, whoever he is.不管他是谁，他也不能把你吃掉。(whoever = no matter who)
注：whoever 引导名词性从句时既用作主格也用作宾语；作宾语时不宜用 whomever，因为在现代英语中 whomever 这个已几乎废弃不用。
4.why 与 because 的用法区别。两者均可引导表语从句，但前者强调结果，后者强调的原因。如： I had a cold.That’s why I didn't come.我感冒了，因此我没来。
I didn’t come.That’s because I had a cold.我没有来，那是因为我感冒了。
四）名词性从句的语序
名词性从句的词序与陈述句语序相同，尤其注意那些由连接代词who(m), whose, which, what 和连接副词 when, where, why 等引导的名词性从句，不要受它们在特殊疑问句中用法的影响而误用疑问句词序。如：
Why was he crying? 她为什么在哭？
I don’t know why he was crying.我不知道她为什么哭。
（五）名词性从句的时态问题
1.当主句的谓语动词是过去式时，宾语从句若不是一个客观事实或真理，其谓语动词也必须用某种过去时态。如： She said that she didn't want to know.她说她不想知道。I asked her whether she would agree.我问她是否会同意。
2.when, if 这两个词既可引导名词性从句，也可引导状语从句。当它们引导名词性从句且表示将来意义时，要直接使用将来时态；但当它们引导状语从句且表示将来意义时，则必须用一般现在时表示将来意义。如：
I don’t know when he will come, but when he comes, I’ll call you.我不知道他什么时候，但当他来的时候，我会打电话给你。
句中第一个when 引导的是宾语从句，故用将来时态表示将来意义；第二个when 引导的是时间状语从句，故用一般现在时表示将来意义。
三．解题方法灵活用
从句的解题方法或步骤：
第一步：先分析出大的类别—— 定从？/名从？/状从？ 即分析所缺部分在主句中的成分 从而确定从句大的类别 第二步：口诀逐一解决：
(I)名词性从句。口诀——先成分后含义
(II)定语从句。口诀——先成分后先行词
(III)状语从句。口诀——翻译即可
在本专题中，名词性从句的口诀执行方法是：
分析引导词在从句中的成分
A 做名词性成分——what/which/who/as(+wh-ever型)
B 做非名词性成分
a 不做成分：that/if/whether(whether霸王原则)
b 做状语成分：when/where/why/how
一旦分出AB两类，剩余的靠含义直接翻译即可解决。
例如A computer can only do _________ you have instructed it to do.(01年31题)
A.how B.after C.what D.when
解：第一步：先分析出大的类别
A computer can only do中的do是及物动词，后面缺少do的对象，所以考察名词性从句问题
第二步：口诀——先成分后含义
从句you have instructed it to do中的do是及物动词，后面缺少do的对象，所以前面的空在后面的从句内充当名词性成分，所以可以选择的引导词就可以排除AD(因为这两个引导词在从句中是充当状语的)，而选项B是名词性从句中不存在的引导词，所以B也不对，最后就剩下一个正确选项C
如此这样一步一步下来，逐一进行排除和选择，最终总是可以直接定位到正确的答案。而这个过程应该是完全被熟化在脑中的一个过程，按部就班的操作直至正确答案自然而然的浮出水面。
其他类别的题目也应该仿照此类，依次完成。

DABCD
真题答案 【答案及解析】：
1B 句意为：会议将被延期的通知大约下午两点发布。空格后的句子解释说明名词the notice，作同位语从句，连接词在从句中不作任何成分，所以用that。25．Can you tell me________it was________your cellphone was lost? 6-10.BABCD 11-15.ADCCA 16-20.DABCA 21-25.BBDDA 26-30.BCDCC
61-65 31-35.ABCDC 36-40.DABBC 41-45.CCDDD 46-50.ACBAA 51-55.CCCAD 56-60.ACBBA
96-100 CCCBD 66-70 CACDB 71-75 CBBCA
86-90 ABDBA
91-95 CABCB 76-80 CCCCD 81-85 BADBC 2 D 句意为：那个人为什么没尽快地报道那场事故还没弄清楚。由句意可知只有D项符合题意。
3C本题考查名词性从句的用法。句意为：你在会上所说的话为公司勾画了一个光明的未来。选项中只有what既可以引导主语从句，又可以在从句中作宾语，因此符合题意。
4B考查名词性从句。句意为：这本书的非凡之处在于作者富有创造性的想像力。________ makes the book so extraordinary为主语从句，从句缺少主语，要用what引导，故选B项。C考查名词性从句。句意为：专家们相信，人们只有当有必要购物时去买东西，这样才可以少浪费食物。believe后跟宾语从句，且宾语从句不缺任何成分。故选C项。D考查名词性从句。what引导主语从句并在从句中作宾语。that引导主语从句但不作任何成分；which表示哪一个；whether表示是否。
7A考查宾语从句引导词的辨析。句意为：不要让任何的失败阻碍你，因为你永远不知道成功离你有多近。分析句子成分后可知，tell后接的是宾语从句；根据语境可知此处用副词how修饰形容词close。
8D考查宾语从句引导词的辨析。句意为：警察发现了疑似曾失窃的古代雕像。分析句子结构可知found后为宾语从句，从句中缺少主语，因此用what引导宾语从句，同时作从句的主语。
9B考查同位语从句连接词。空格后面的从句解释说明belief的具体内容，是同位语从句，且从句中不缺少任何成分，所以用that引导。
10D考查名词性从句——宾语从句。根据语境可知，know后是宾语从句，从句完整，用that起连接作用。所以答案选D项。
11C考查名词性从句连接词辨析。句意为：电影中给我留下深刻印象的是父亲对儿子深深的爱。“________ struck me most in the movie”在句中作主语，且该主语从句中谓语动词struck缺少主语，故选择what(＝the thing that)。that引导主语从句不担任成分；it不是连词；which“(无论)哪一个”，表示在一个限定范围内进行选择，均不符合题意。
12Dit是形式主语，空格后是一个主语从句，从句中的谓语动词do缺少宾语，此处所填单词既要引导主语从句，又在从句中作宾语，四个选项中有此功能的只有what。句意为：总统能采取什么措施来结束这场罢工根本不为人所知。
13B句意为：在这家商店里，无论你用现金支付还是用信用卡支付都无关紧要。由It doesn’t matter“没关系”可知后面的意思应该是“无论(不管)„„还是„„”，又根据题干中的关键词or就很容易确定选B项，构成固定搭配whether...or...。how如何；what什么；why为什么，均不符合题意。
14B句意为：一个人的智力极限，通常来说，出生时就已经定型了。但他是否能够达到这些极限则取决于他所处的环境。根据depend on可知，主语从句含有不确定因素，可排除C项。where表示地点；why表示原因，用于此处不合适；而使用whether表示“是否”，与题意吻合。
15C that引导同位语从句，在从句中不作句子成分，补充说明promise的内容。
16A 句意为：在这个十字路口你向左或向右转弯都没有关系，因为两条路都通向公园。题干中it作形式主语，所以所选的连词在句中引导主语从句。whether引导名词性从句表示“是否”之意，而且题干中出现了关键信息词or。whether...or...表示“是„„还是„„”。if引导名词性从句也表示“是否”，但引导主语从句、表语从句、同位语从句等只能用whether而不能用if。
17B考查名词性从句。所填词引导的从句作动词choose的宾语，引导词在从句中作主语，意为“无论哪件”，故选B。其余选项与句意不符。
18C句意为：杰里不后悔给出评论，但是他觉得他本来可以用另一种不同的方式来表达。felt后面应该是一个宾语从句，分析宾语从句可知，这是一个完整的句子，不缺句子成分，故用that引导。
19DIt occurs/occurred to sb.that...某人想到/想起。it是形式主语，主语从句成分完整，不能用连接代词which引导，whether与where不符合句意。故选D项。
20B考查名词性从句。句意为：科学家研究人类大脑是如何工作的以制造电脑。分析句子结构可知 study后接宾语从句，从句中缺少方式状语，故选B项。模拟【答案及解析】： A主语从句中缺少主语，而能在主语从句中既充当主语又起引导作用的只有what。D wonder后面的宾语从句本是“what makes him so excited”，但what需要被强调，故用强调句型。3A考查名词性从句的连接词。句意为：看似简单平常的水是使生命出现成为可能的东西。what引导表语从句并在句中作主语。
4B 所填词在宾语从句中作主语。who表达的意思不对，也不符合句子结构；whomever不能在句中作主语；no matter who不能引导名词性从句。
5C宾语从句中you think是插入语，从句中缺少主语，which意思不对，故选what。
6A考查同位语从句。if不能引导同位语从句；句中缺少疑问词“是否”，故选A项。句意为：史密斯先生问了男孩一个问题，问他是否能和他一起去音乐会。
7C考查同位语从句。that引导的从句是对a warm thought的解释说明。句意为：我突然产生了一个温情的想法，在母亲生日那天我可以用零用钱给她买花。
8Ahat引导同位语从句，具体说明chance(可能性)的内容。
9A本题考查宾语从句的连接词。该连接词既引导了宾语从句，又在句中作needed的宾语，故只有what符合题意。10A第一空是定从，修饰the reason，故用why；第二空是表从，从句中不缺少主要成分，故填that。11B pleased后面缺少宾语从句，he was a man of action句意完整，故用that引导。
12B本题考查同位语从句。reason后面有for引导的短语，接着后面是that引导的同位语从句来说明reason的内容。13C本题考查宾语从句。介词for后接宾语从句但宾语从句中缺少主语，he thought是插入语，连词what引导宾语从句且在从句中充当主语，which的意思不符合。
14C介词from后是宾语从句，但从句中it had been后面少表语，所以what符合语意。
15C这取决于我们是否能得到Green先生的配合，on后宾从句中含有不确定因素故用whether引导。if不能引宾从 16C________ wants to stay in a hotel为主语从句，从句中缺少主语，A、B两项可作主语，但不是连词，故排除。who只有疑问的意思，意为“谁”；whoever意为anyone who “任何„„的人”，符合题意。D可把此处的he thought作为插入语，what作宾语从句的主语。句意为：那位老板拒绝以不满意的价钱卖车。18Awhether...or...或者„„或者„„，whether引导的从句为真正的主语，it为形式主语。19D考查表语从句。结合语境“这就是误解产生的原因”可知，此处应用why引导表语从句。
20B句意为：在大甩卖开始前，我把孩子们在下个季节里要用到的东西列了一个清单。分析句式结构可知，空格处在句中引导宾语从句且在从句中充当need的宾语，which引导名词性从句时多表示疑问且要有一个明确的范围。
21B第一空可填which或that来引导定语从句，而第二空的表语从句必须用that引导。B根据句意及句子结构可知该句为主语从句，故排除D项；又因语境中含有“是否”之意，故排除C项；whether引导的主语从句可置于句首，但if引导的主语从句只能用it作形式主语，而把从句放在句末，故排除A项。
23C句中有介词to，可知空格处引导宾语从句。空格后的I think可看作插入语，句子缺少主语，用whoever，表示“任何„„的人”。who没有这种意思；whomever在句中作宾语。D考查名词性从句和定语从句的引导词。第一个空中what引导一个主语从句，并作从句的主语。第二个空代替先行词the old worker，并作介词for的宾语，用whom。
25Awhere引导宾语从句，且从句中包含强调句型。

参考答案及解析
1.A.which用作关系代词，在定语从句中作主语。
2．C.“和谁讲话”要说speak to sb.本题全句应为Do you know the man whom I spoke to.。whom是关系代词，作介词to的宾语，可以省略。
3.D.where是关系副词，表示地点，在定语从句中作地点状语。4.C.when是关系副词，表示时间，在定语从句中作时间状语。
5．A.which是关系代词，在从句中作forget的宾语。其他几个答案都不能作宾语。6．C.解析同第5题。7.A.解析见第3题。
8.A.本句话的先行词应该是films,因此，关系代词that是负数概念，其谓语动词应用复述的被动语态have been shown。如果句中的one前面使用了定冠词the，则the one应该视为先行词。
9.A.“谈到某事物”应说talk about sth.。about是介词，其后要用which作宾语，不能用that。
10.A.with which是”介词+关系代词“结构,常用来引导定语从句.with有”用“的意思,介词之后只能用which,不能用that.with which在定语从句中作状语,即he is writing with a pen.11.C.in front of which 即in front of a farmhouse.In front of which在从句中作状语.12.D.with whom引导定语从句.with whom放在从句中即为:my father works with the engineer.13.D.whose引导定语从句,在从句中作主语family的定语.14.A.that引导定语从句,因为先行词是all,所以只能选用that引导.15.D.the same……..as是固定用法, as引导定语从句时,可以作主语,宾语或表语.在本句话中,as作从句的主语.16.D.such……… as是固定用法,as引导定语从句时,可以作主语,宾语或表语.在本题中,as作表语.17.B.as作关系代词可以单独用来引导非限制性定语从句。这时as所指代的不是主句中某个名词，而往往指代整个主句的含义。as在从句中可以作主语、宾语。从句可放在主句后，也可置于主句前。在本句中,as作宾语.18.B.Li Ming enjoyed it very much是主句,with whom I went to the concert是定语从句.with whom放在从句中为:I went to the concert with Li Ming.19.C.as引导定语从句时通常构成such…as或the same…as固定搭配，其中such和same修饰其后的名词，as为关系代词，指代其前的名词引导定语从句。as在从句中可以作主语、表语或宾语。Such修饰单数名词时,要用such a……..,本题中such books, such直接修饰复数名词.50.All that can be eaten _______ eaten up.B.has been 20.B.things和persons是先行词.当定语从句要修饰的先行词是既表示人,又表示物的名词时,其关系代词要用that.21.D.who引导非限制性定语从句,who作从句的主语.22.C.two thirds of whom 即:two thirds of the 2,000 workers.23.D.先行词person后有两个定语从句,第一个从句省略了关系代词whom.因为, whom作从句中met的宾语,可以省略.第二个从句who could do it.who在从句中作主语,不可省略.24.A.whose title引导非限制性定语从句,whose title也可以说成the title of which 25.A.for which 引导定语从句,使用介词for,是来自于从句中的固定短语 be famous for ”以……..而闻名".26.C.当先行词被such修饰时,引导定语从句的关系代词要用as.As在本从句中作主语.27.A.两个先行词the day都是表示时间的名词,但第一个空白处要填的关系词在从句中作状语,因此要用关系副词when.第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which或that来引导定语从句.28.D.在way、distance、direction等词后的定语从句中，常用that来代替“in(或其他介词)+which”、when或where，而that常可省略。
29.D.for which在定语从句中作原因状语,可用why 来替代.30.B.which I have looked after 构成一个非限制性定语从句.31.A.The reason why… was that….已成为一种固定句型，这一句中的why和that不能随意换位，也不能将that改成because，尽管that这个词在译文中可能有 “因为”的含义。32.B.非限制性定语从句常用which引导,which表示前句话的整个含义.33.A.解释见28题.34.D.主句中的two表明不能选A.从句中的are表明不能选B.both of which用来引导非限制性定语从句.35.C.as引导定语从句时通常构成such…as或the same…as固定搭配，其中such和same修饰其后的名词，as为关系代词，指代其前的名词引导定语从句。as在从句中可以作主语、表语或宾语。本题中as作从句的主语.36.B.非限制性定语从句常用which引导,which表示前句话的整个含义.37.D.38.D.解析见35题.39.A.he makes是定语从句, 从句前省略了关系代词that.40.B.which is a bad habit 非限制性定语从句.41.A.what happened是宾语从句.all 之后that he knew是定语从句.先行词是all,所以关系代词只能用that.42.D.years是表示时间的名词,用when引导定语从句,是因为when在从句中作时间状语.第二个空选用which,引导一个非限制性定语从句.43.C.本句话的定语从句是who own cars.其先行词是people,因此,定语从句的谓语动词要用复数的own。本句话主句的主语是The number of指“…..的数目”，是单数概念。因此，主句的谓语动词要用is。44.D.that followed是定语从句，关系代词that在从句中作主语。45.A.先行词gas被only修饰，关系代词要用that，而不用which。
46.B.through which引导定语从句，through which即through the hole,在定语从句中作状语。What引导的是see的宾语从句，并作从句的主语。47.B.为便于理解，改写本句话：This is the school that some Germanfriends visited last week.不难看出，作表语的the school是先行词。that引导了定语从句，因为that同时又作visited的宾语，所以被省略了。其它选项结构不对。48.A.解释见35题。
49.C.因为是two ballpens, 并且定语从句的谓语writes是单数概念。因此，C是正确选项。
50.B.本句话中，主句的主语是all,为抽象概念。因此，其谓语应用单数的has been。关系代词that引导定语从句，并在从句中作主语。

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。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面 1.考查名词性从句的语序问题 2.考查引导词that与what的区别
4.考查whether与if的区别
6.考3.考查it在名词性从句中作形式主语或形式宾语的用法 查名词性从句的虚拟语气问题 语法要点剖析
一、名词性从句
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。
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 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： What he wants to tell us is not clear.他要跟我们说什么，还不清楚。
我们都知道他是如何成为一名作家的。It is known to us how he became a writer.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。常用句型如下：（1）It + be + 名词 + that从句
（2）It + be + 形容词 + that从句（4）It + 不及物动词 + that 从句（3）It + be + 动词的过去分词 + that从句 常用的句型有：
It is necessary(important, natural, strange, etc.)that …
It is a pity(a shame, no wonder, etc.)that…
It is suggested(requested, proposed, desired, etc.)that… 2.宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。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。例如：
5.考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别
Where the English evening will be held has not yet been announced.另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should)+do”，He has told me that he will go to Shanghai tomorrow.我们决不能认为自己什么都好，别人什么都不好。
他已经告诉我他明天要去上海。
We must never think(that)we are good in everything while others are good in nothing.注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如： I insist that she(should)do her work alone.我坚持要她自己工作。
The commander ordered that troops(should)set off at once.司令员命令部队马上出发。
2.用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。
例如： I want to know what he has told you.我想知道他告诉了你什么。
She always thinks of how she can work well.她总是在想怎样能把工作做好。
She will give whoever needs help a warm support.凡需要帮助的人，她都会给予热情的支持。
3.用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：
a.引导主语从句并在句首时；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。
例如： Whether there is life on the moon is an interesting question.月球上有没有生命是个有趣的问题。
Everything depends on whether we have enough money.一切要看我们是否有足够的钱。4.注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用 不同时态。
例如： he studies English every day.（从句用一般现在时）he studied English last term.（从句用一般过去时）
I know(that)he will study English next year.（从句用一般将来时）he has studied English since 1998.（从句用现在完成时）
当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：The teacher told us that Tom had left us for America．
5.think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。
例如： We don’t think you are here.我们认为你不在这。I don’t believe he will do so.我相信他不会这样做。3.表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。例如： The fact is that we have lost the game.It looks as if it is going to rain.事实是我们已经输了这场比赛。那就是他为什么不到会的原因。That is why he didn’t come to the meeting.看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如： The reason why he was late was that he missed the train by one minute this morning
4.同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：
The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。I have no idea when he will come back home.我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill.他想到可能玛丽生病了。同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）

名词性从句讲解
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。历届高考试题名词性从句考查的焦点主要有以下5个方面 1.考查名词性从句的语序问题
2.考查引导词that与what的区别
3.考查it在名词性从句中作形式主语或形式宾语的用法
4.考查whether与if的区别
5.考查名词性从句的虚拟语气问题 语法要点剖析
一、名词性从句
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。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 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： What he wants to tell us is not clear.他要跟我们说什么，还不清楚。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。常用句型如下：（1）It + be + 名词 + that从句
（2）It + be + 形容词 + that从句（3）It + be + 动词的过去分词 + that从句
（4）It + 不及物动词 + that从句 It is a pity(a shame, no wonder, etc.)that„
It is necessary(important, natural, strange, etc.)that „ It is said(reported, believed, known, etc.)that„ It does not matter(seems,appears etc)„ 2.宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。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不可略，且并列句之间由and连接。He has told me(that)he will go to Shanghai tomorrow.他已经告诉我他明天要去上海。He found(that)he lost himself in the forest and that he had no way to dicide the right directions.他发现自己在树林里迷路了，而他又无法确定正确的方向。
注意：在demand、order、suggest、insist, desire,等表示要求、命令、建议、等意义的动词后，宾语从句常用“（should）+ 动词原形”。
I insist that she(should)do her work alone.我坚持要她自己工作。2.用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。I want to know what he has told you.我想知道他告诉了你什么。
She always thinks of how she can work well.她总是在想怎样能把工作做好。
She will give whoever needs help a warm support.凡需要帮助的人，她都会给予热情的支持。3.用whether或if引导的宾语从句实为一般疑问句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：
a.引导主语从句并在句首时；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；
Whether there is life on the moon is an interesting question.月球上有没有生命是个有趣的问题。Everything depends on whether we have enough money.一切要看我们是否有足够的钱。
4.注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用 不同时态。
I know(that)he will study English next year.（从句用一般将来时）
当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。
The teacher told us that Tom had left us for America． Our teacher told us that the earth runs around the sun
5.think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。We don’t think you are here.我们认为你不在这。I don’t believe he will do so.我相信他不会这样做。3.表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。
The fact is that we have lost the game.事实是我们已经输了这场比赛。That is why he didn’t come to the meeting.那就是他为什么不到会的原因。It looks as if it is going to rain.看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如： The reason why he was late was that he missed the train by one minute this morning 4.同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如： The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。I have no idea when he will come back home.我不知道他什么时候回来。同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life ？（that引导定语从句，作宾语，可以省略）
第四篇：名词性从句讲解
名词性从句与高考试题
名词性从句的界定与分类：
名词性从句相当于名词，可分别作主句中的主语、表语、宾语和同位语。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。从属连词that, if, whether;
连接代词who, whoever, whom, whomever, which, whichever, what, whatever, whose;连接副词where, when, why, how。
其中, 从属连词只起连接作用, 在从句中不充当任何句法成分，而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分.名词性从句均不能用逗号和主句分开。
一、主语从句：
定义：一个从句在复合句中作主句的主语，这个从句就叫主语从句。
二、主语从句的表现形式： １.由从属连词引导的主语从句：
a.Whether the country should build a nuclear power station is something we must discuss.b.That light travels in straight line is known to all.２.由连接代词引导的主语从句： a.What we need is more time.b.Whichever book you choose doesn’t matter to me.c.Whoever comes will be welcome.３.由连接副词引导的主语从句：
a.When the plane is to take off hasn’t been announced ． b.Where he has been is still a puzzle.c.How much water is flowing can be measured easily.三、关于形式主语 it
主语从句放在句首往往显得头重脚轻，不太平衡，因此，在大多数情况下都是在主语的位置上用一个形式主语 it，而把主语从句移到句未去。
关于形式主语 it: 以 it 作形式主语，把主语从句后置的常用句型有：（1）It + be + 形容词 + that/wh-从句
It is quite clear that Tom was fond of music.（2）It + be + 名词 + that/wh-从句
It is a pity that she has made such a foolish mistake.可应用于此句型的名词还有fact / shame / honor / question等。（3）It + be + 过去分词 + that/wh-从句
It’s not yet decided that when the test will be given.（4）It seems, happens 等不及物动词 + that/wh-从句 It happened that I didn’t take any money with me.但以下情况往往必须用it作形式主语，主语从句一般不能放在句首。a.It doesn’t matter whether he likes or not.b.It’s said that the highway will be open to traffic next year.c.Is it likely that it will snow in the afternoon? 练习：
1． ____ you don't like him is none of my business．（92上海）A．What B．Who C．That D．Whether A．What B．That C．This D．Which

6． ____ he said at the meeting astonished everybody present．（MET93）A．What B．That C．The fact D．The matter 二, 表语从句：
定义：一个从句在复合句中作主句的表语，这个从句就叫作表语从句。可以接表语从句的连系动词有 be, look, remain, seem 等。
1.The problem is that millions of people die of illnesses caused by smoking.2.The question remains whether we can win the people.3.That’s just what I want.4.This is where our problem lies.5.The difficulty is how I can help smokers kick their habit.值提注意的是：
1.表语从句的表现形式除了用从属连词，连接代词和连接副词引导以外，还可以由as, as if ,as though引导.Things were not as they seemed.It looks as if it is going to rain.2、另外还要注意以下常用的两种结构：
The reason why…is that …(而不用 because。)It(this, that)is because…
The reason why he was dismissed is that he didn’t work hard.It is because the tobacco companies want to remain in business.练习：
1.What the doctors really doubt is____ my mother will recover from the serious disease soon．
A．when B．how C．whether D．why
2.—I drove to Zhuhai for the air show last week． —Is that ____ you had a few days off？（NMET99）A．why B．when C．what D．where
3.Go and get your coat．It's____ you left it．（MET92）A．there B．where C．there where D．where there
4.I had neither a raincoat nor an umbrella．____I got wet all through．（98上海）A．It's the reason B．That's why C．There's why D．It's how 三，同位语从句：
定义：在复合句中，用作同位语的从句称为同位语从句。
同位语从句一般由 that, whether 等连词引导，常放在 advice, doubt, fact, hope, idea, information, message, news, order, possibility, problem, question, reason, truth, word, suggestion.等名词的后面，说明该名词的具体内容。
l.The news that he had landed on the moon spread all over the world.2.I have no idea when he will be back.3.The thought came to him that Mary had probably fallen ill.4.He must answer the question whether he agrees to it or not.同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）
练习：
1.Information has been put forward____ more middle school graduates will be admitted into universities．（2001上海）
A．while B．that C．when D．as
2.______ is no possibility _______.Bob can win the first prize I the match.(上海2001春)A、There;that B、It;what C、There;whether D、It;whether 四，宾语从句
定义：一个从句在复合句中作主句的宾语，这个从句就叫作宾语从句。宾语从句可以作及物动词的宾词，介词的宾语，某些形容词的宾语以及非谓语动词的宾语。1．及物动词后的宾语从句：
She will give whoever needs help a warm support.I wonder why she refused my invitation.2．介词后的宾语从句：

2.动词 doubt 用在疑问句或否定句时，其后宾语从句常用 that 作连接词；用在肯定句时，连接词用 whether 或 if 皆可，而不用 that。
Do you doubt that he will win ? I don't doubt that your proposition is wrong.He doubt whether I know it.3.否定转移问题。在主句为第一人称主语后跟 think , believe , suppose , expect , guess , imagine 等动词时，宾语从句的否定形式应转移到主句中。We don't expect he will come tonight , will he ? 4.主谓一致问题。
What he wanted to see was an end to all the armies of the world． What I bought were three English books． 5.语气问题
a.在含有 suggest , order , demand , propose , command , request , insist, desire, require, advise 等表示要求、命令、建议、决定等意义的动词后，that从句常用“（should）+ 动词原形”的结构
I suggest we(should)set off at once.b.在It is ＋过去分词＋that的主语从句中 decided，demanded，desired，insisted，ordered，proposed，suggested，recommended，requested，required等。It is desired that we（should）get everything ready this evening． c.在表语从句或同位语从句中。
The suggestion that the mayor(should)present the prizes was accepted by everyone．
d.在It is（was）＋形容词＋that从句中要用虚拟语气，即（should ＋）动词原形，表示建议或不满、惊奇等情绪。常用于此类的形容词有 essential，important，natural，necessary，possible，strange，等。It is necessary that a college student ________ at least a foreign language．（上海1993）
A．masters B．should master C．mastered D．will master 6．What引导名词从句的特殊含义:
What was once regarded as impossible has now become a reality．
(what为“所……的事”，相当于“the thing that．．．；all that．．．；everything that．．．”)After ________ seemed a very long time，I opened my eye and found myself in bed．
A．what B．when C．that D．which

第五篇：名词性从句及习题
高中语法
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。 语法要点剖析
一、名词性从句
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。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
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,不充当成分，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：
What he wants to tell us is not clear.（what既保留自己的疑问含义，又起连接作用，并从句中充当成分）
It is known to us how he became a writer.（how既保留自己的疑问含义，又起连接作用，并从句中充当成分）
Where the English evening will be held has not yet been announced.（where既保留自己的疑问含义，又起连接作用，并从句中充当成分）
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。常用句型如下：
（1）It + be + 名词 + that从句
（2）It + be + 形容词 + that从句（3）It + be + 动词的过去分词 + that从句（4）It + 不及物动词 + that 从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should)+do”，常用的句型有：
It is necessary(important, natural, strange, etc.)that „ It is a pity(a shame, no wonder, etc.)that„
It is suggested(requested, proposed, desired, etc.)that„
表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。
其基本结构为：主语 + 系动词 + that从句。例如： The fact is that we have lost the game.That is why he didn’t come to the meeting.It looks as if it is going to rain.需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如： The reason why he was late was that he missed the train this morning
宾语从句
在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句.234567891011-
