第一篇：名词性从句易混点剖析
名词性从句易混点剖析
名词性从句是高考语法考查的热点之一，几乎在历年各地的高考试卷中都有涉及。而不少同学往往因为分不清从句之间的细微差别而不能正确把握其结构，从而导致考试丢分。笔者在此就名词性从句中的几大易混点进行分析，帮助同学们攻克名词性从句的重难点。
[易混点一 连接代词和连接副词的误用]
名词性从句的连接代词包括who，whom，whose，what，which，whoever，whomever，whosever，whatever，whichever等，在从句中充当主语、表语、宾语；连接副词包括when，where，why，how，whenever，wherever，however等，在从句中主要充当各种状语。
例1 She asked me _______ I had returned the books to the library，and I admitted that I hadn’t.A.when B.where C.whether D.what
解析 C。句意：他问我是否已经把书还给图书馆了，我承认我还没有还。
例2 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。
点拨 若从句缺少主语、宾语、表语或定语，则考虑用连接代词；若从句缺少时间、地点、原因、方式等状语成分，则使用连接副词。
[易混点二 what和that的误用]
例3 The manager put forward a suggestion ________ we should have an assistant.There is too much work to do.A.whether B.that C.which D.what
解析 B。句意：经理提出一个建议，我们应该有个助手。要做的工作太多了。使用同位语从句说明suggestion的内容。同位语从句成分和意思都是完整的，that不作成分，只起连接作用。
例4 Eventually，I decided to follow her and _______ happened truly amazed me.解析 what。句意：发生的事情真让我很惊讶。设空处无提示词，分析从句的结构可知，从句缺少主语，且指代的是物，可判断应填what引导主语从句。
点拨 解答这类题目，关键在于分析清楚句子结构，知道设空的含义以及充当的成分，从而选择正确的引导词。
[易混点三 if和whether的误用]
if和whether在名词性从句中不充当成分，不可省略。在表达是否这一含义时，我们经常用whether或if来引导名词性从句，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 support us.3.在不定式之前。如：
He doesn’t know whether to stay or not.4.从句中有or not时。如：
He doesn’t know whether he should stay or not.例5 The doctor can hardly answer the question if the old man will recover soon.解析 if→whether。question后为同位与从句，只能用whether来引导。
[易混点四 wh-ever的误用]
名词性从句中的wh-ever形式，包含连接代词whoever，whomever，whosever，whatever，whichever和连接副词whenever，wherever，however等，同学们必须分清他们的含义和用法。
例6 Your support is important to our work.________ you can do helps.A.However B.Whoever
C.Whatever D.Wherever
解析 C。考查主?Z从句。本题中，helps是谓语，you can do是主语部分，在主语从句中，do后缺少宾语，whatever引导主语从句，同时作do的宾语。句意：你能做的任何事都有帮助。因此用whatever引导。
例7 Every year，_______ makes the most beautiful kite will win a prize in the Kite Festival.A.whatever B.whoever
C.whomever D.whichever
解析 B。句意：每年，任何一个做出最漂亮的风筝的人将会在风筝节获奖。
注意 wh-ever在引导名词性从句时不能用no matter wh-替换，但在引导状语从句时可以。如：
Whatever happened，he would not mind.=No matter what happened，he would not mind.点拨 连接代词whoever，whatever，whichever引导名词性从句时，相当于anyone who，anything that等；引导让步状语从句时，相当于no matter who/what/which。
[易混点五 与其他从句混淆]
不少同学在学习使用名词性从句时，经常将它与其他从句，尤其是与定语从句以及强调句搞混。那么，我们应如何弄清楚他们之间的区别呢？
1.主语从句与定语从句混淆
例8 21.It is often the case ______ anything is possible for those who hang on to hope.A.why B.what C.as D.that
解析 D。考查主?Z从句。本句中it是形式主语.真正的主语是连接词that做引导的主语从句，连接词that在本句中不充当任何成分，只是一个引导词而已。句意：对那些心存希望的人而言，一切皆有可能。
请同学们比较：
It is often the case that anything is possible for those who hang on to hope.As is often the case，anything is possible for those who hang on to hope.What is often the case is that anything is possible for those who hang on to hope.第一句为主语从句，it作形式主语；第二句为as引导非限制性定语从句，指代整个主句内容；第三句为what引导的主语从句，what在句中充当主语。
2.同位语从句与定语从句混淆
例9 During their trip in Chinatown，Judy and Nick know the fact which people mainly from America，Singapore，and Canada，Vietnam are living here.解析 which→that。句意：在他们到中国城的旅行中，Judy and Nick了解到住在这里的人主要来自美国、新加坡、加拿大和越南等地。the fact后的从句对the fact起说明作用，应该是同位语从句，且从句句意完整，故应用that。
定语从句与同位语从句：二者前通常都有名词或代词，但定语从句起修饰、限定作用；同位语从句起解释、说明作用。试比较：
Judy and Nick are surprised at the fact that Canada is such an empty country.Judy and Nick are surprised at the fact that shows Canada is an empty country.第一句中，that后的句子说明fact的内容，且句子意思完整，连接词只起连接作用，引导同位语从句；第二句that后的句子起修饰限定的作用，横线上的词在句子中作show的主语，引导定语从句。
3.名词性从句与强调句混淆
例10 11.It was when I got back to my apartment ______ I first came across my new neighbors.A.who B.where C.which D.that
解析 D。句意：当我回到我的公寓的时候，我第一次遇见了我的新邻居。本句去掉it was和空格，句意完整，所以本句是强调句型，强调的是时间状语when I got back to my apartment，应用that。同学们切不可误认为此句是主语从句，将it当作形式主语。
第二篇：名词性从句
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.名词性从句的分类如下
（一）主语从句
主语从句的句型.引导词有疑问词wh-及whether/if及that.1、主语从句在复合句作主语。疑问词引导e.g.Who will go is not important.2、用it作形式主语，主语从句放在句末。
3、If/whether 引导e.g.It doesn’t matter so much whether you will come or not.4．It+be+adj(obvious,true,natural,surprising,good,wonderful,funny,likely,certain,probable,etc)/名词词组（no wonder,an honor , a good thing,a pity,etc)+that从句 e.g.It’s certain that she will do well in the exam/It’s no surprise that our team has won the game.5．It+be+过去分词（said,reported,thought,expected,decided,announced,etc)+that从句
e.g.It’s said that Mr.Green has arrived in Beijing.Note:that引导主语从句时，在口语和非正式文体中可以省略，但that从句置于开头时不能省略。e.g.That he suddenly fell ill last week made us surprised.（二）表语从句
表语从句的句型及要点。引导词疑问词wh-及whether及that.1、表语从句在复合句中作表语，位于系动词之后。疑问词引导的： e.g.The question was who could go there.Note: 引导表语从句的连接词that一般不可省去。
e.g.My idea is that we can get more comrades to help in the work.连接词that一般不能省略，但当主句中含动词do的某种形式时，that可以省略。如： What I want to do is(that)I can go up to him and thank him.我想做的事是走到身边去感谢他
（三）宾语从句
宾语从句在复合句中作宾语。引导词有疑问词wh-及whether、if(if 和whether 有区别）及that.引导宾语从句的连词that一般可省略。e.g.I hope(that)everything is all right.Note:以下情况that不可省略：(不考查）
1.当宾语从句的主语是that时。2.2.当宾语从句中含有主从复合句时 Father promised that I studied harder he would take me to Beijing.3.当两个或多个宾语从句由并列连词连接时，除第一个从句中的that可以省略外，其余从句中的that都不可以省略。
4当that偶尔作except和in的宾语时。This book is unsatisfactory in that it lacks a good index.中，that it lacks a good index就是介词 in 的宾语从句，这当中的that就不能省略。
（四）同位语从句。引导词wh-及whether及that.同位语从句引导词有疑问词wh-及whether及that.同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。e.g.I have no idea when he will be back.The fact that he had not said anything surprised everybody.名词性从句易混知识归纳
易混点一 ：同位语从句与定语从句的区别
that引导的从句，是定语从句还是同位语从句，我们我们采用“试加 法”，来判断。The fact that he had not said anything surprised everybody.This is the fact that you must know clearly.1.when、where、why引导的从句
引导定语从句时，其意义与先行词有关，与先行词的意义基本相同，没有疑问意义；但引导同位语从句时，其意义完全与疑问词相同，即when表示什么时候，where表示哪儿，引导两种从句时，都在从句中做状语。如： I still remember the day when I first came to Beijing.句中的when相当于“on the day”它没有疑问词“什么时候”的意义，因此是定语从句。
I have no idea when she will be back.when与idea毫无意义上的关联，其意思是“什么时候”,因而是同位语从句。易混点二：reason后面的名词性从句
reason做主语时，后面的表语从句表示原因是要用that引导，一般不用because或why，而用it，this或that做主语时，后面的表语从句可用because或why引导。
1.“The reason +连系动词+that“引导的表语从句。本句型的意思是：理由是：。。。The reason was that he fell ill.2.It（或This、That）+连系动词+the reason+why引导的定语从句。本句型意为：这就是。。。的原因（理由）That is the reason why he failed in the contest, 3.It（或This、That）+连系动词+the reason+because引导的表语从句。本句型意为：这是因为。。。；这是由于。。。的缘故。That was because he fell ill.4.It（或This、That）+连系动词+why引导的表语从句。本句型意为：这就是。。。的原因。
That was why he fell ill.易混点三：what、whatever、who、whoever等引导的名词性从句 我们可以通过与定语从句的转化知道两组在意义上的差别。Whatever=anything that（无论什么）Whoever=anyone who（无论谁）
Whenever=any time=no matter when（无论何时）Wherever=any place=no matter where（无论何地）这都是泛指。而what、who、when、where则是特指。如： Who spoke at the meeting is unknown The person that spoke at the meeting is unknown.Whoever breaks the law will be punished.Anyone who breaks the law will be punished.注意：1.whatever、whoever、whenever、wherever等常引导主语从句、宾语或表语从句，也可以引导状语从句，等于“no matter +疑问词”。而no matter +疑问词只能引导让步状语从句。Eg：Whatever I said/No matter what I said, he wouldn’t listen to me..2whoever的宾格还是whoever，一般不用whomever。易混点 whether与if（不做考查）
二者都可以作“是否”讲，能引导名词性从句，都不能省略。1.在及物动词后引导宾语从句时可以互换；
注意：在某些动词后（如:discuss）只能接whether，不能跟if。如： We discussed whether we should close the shop.2.引导主语从句、表语从句、同位语从句时都用whether，不用if。如：
The question whether he should come himself or send another man hasn’t been decided.Whether he will win is all the same to me.The question is whether you can go there yourself.但如果主语从句是有It用作形式主语，if和whether都可以 It is unknown whetherif she is ill.3宾语从句中，如果whether后紧跟or not，不用换做if；若whether与or not分开使用，则可以换作if。如： I wonder whether or not he has arrived at the destination.I don’t know whetherif I can come or not.4.若宾语从句为否定结构，则多用if，而不用whether。如： I don’t care if he doesn’t show up.（炫耀）
5.在介词后引导宾语从句或与带to的动词不定式结合而构成不定式的复合结构时，只能用whether，而不用if。如：
I haven’t settled the question of whether I will go back home.She doesn’t know whether to get married now or wait.练习：名词性从句

D.What;that 1.选D。what made matters worse 是主语从句(注意其后有谓语动词was)，相当于 the thing that made matters worse。
2.选A。what 引导的是表语从句，相当于 the thing that it takes to do anything well。3.选C。that 引导的是一个主语从句，句首的it为形式主语。
4.选 C。答句为省略句，其完整形式为 I was trying to prove to the police where I was last
night，在此 where 引导的是一个宾语从句。类似地，下面选 C：
“_______ made her struggle to become an artist so hard?” “______ she was a woman.” A.What, What
B.That, That C.What, That
D.That, What 5.选D。what 引导的是表语从句，what 在此相当于 the things that。
6.选 C。句首的 it 是形式主语，空格处所填词用于引导主语从句。由于该主语从句中又缺主语，故排除A、B、D。（注意：不能选 A，因为 that 引导名词性从句时不能充当句子成分）7.选 A。第一空填 what，是因为该主语从句中的动词 understand 缺宾语；why 和 because 均可引导表语从句，其区别是： why 引导表语从句强调结果，because 引导表语从句强调原因。句中空格后文表明的是结果，故用 why。
8.B。what 在此引导主语从句且在从句作宾语，它相当于 the thing that。
9.B。两空均填 what，均用于引导宾语从句，因为两个宾语从句中的动词 said 和do 均缺宾语，而在各个选项中只有 what 可用作宾语。
10.选 A。what 引导宾语从句。由于动词 wants 缺宾语，所以填 what。句意是：当你找工作面试回答问题时，请记住这条黄金定律：永远给予对方确实想要的东西。
11.选 A。I can to save them 为 I can do to save them 之略，此句中的 do 缺宾语，故选 whatever。
12.选 B。that 在此引导主语从句，无词义，也不充当句子成分。注意不要根据中文意思选 D，因为 because 不用于引导主语从句。13.选 C。两个空格处均为引导宾语从句的引导词，而四个选项中两者可引导宾语从句的只有 C。
14.选 B。比较 That’s why„ 与 That’s because„：前者用于强调结果，后者用于强调原因。如下面一题选 D：
I got wet all through._______ I had neither a raincoat nor an umbrella.A.It’s the reason
B.That’s why C.There’s why
D.That’s because
15.选 D。由 is worth praising 这一谓语可知前面是主语从句，排除不能引导从句的 B 项和 C 项；whoever 引导主语从句表示“任何„„的人”，在此它相当于 anyone who。16.选 A。how 引导主语从句，that 引导同位语从句。
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-
