高考英语名词性从句解题思路和易混考点归纳（7页）
高考英语名词性从句解题思路和易混考点归纳（7页）高考英语名词性从句解题思路和易混考点归纳名词性从句是高考的一项重要内容，掌握其解题技巧很重要。
考查重点名词性从句有四种：主语从句、宾语从句、表语从句和同位语从句。
其中宾语从句是考查的重点，连接词中which, what, where, when, that, whether是考查的热点。
解题思路1．先找出句子的谓语动词，后根据从句在句中的位置来判断它属于哪一种名词性从句；2．先成分后含义——先分析连接词在从句中的成分，后根据含义直接翻译即可；3．若作主语、宾语、表语、定语等成分，则用what(ever), who(ever), whom(ever), whose, which(ever)引导；4．若不作成分，则用that, if, whether引导，只起连接作用；5.若作状语，则用when(ever), where(ever), why引导。
注意:主语从句常放在主句谓语动词之前，it作形式主语除外；表语从句位于系动词后；宾语从句位于动词或介词后；同位语从句位于名词之后。
经典试题例1In the 1980s young people would only wear was in fashion.解题思路首先，从谓语动词would wear可知，此处缺少宾语，再结合空后的系表成分可知，此处应考查从句，即名词性从句的宾语从句。
分析宾语从句可知，此处缺少引导该从句的连词，且该连词在此作主语成分。
结合句意“在19世纪80年代，年轻人只穿流行的衣服”可知，此处需填what。
例2he is a famous singer is known to us.解题思路首先，分析空后句子成分可，is known才是主句的谓语，由此可以判断“he is a famous singer”是作句子的主语，即考查名词性从句的主语从句且主语从句不缺成分，故需填只起连接作用的That即可。

4．同位语从句
结构：,名词＋连接词＋从句主语＋从句谓语＋其他。 位置：常放在fact, news, idea, truth, hope, problem, information, belief, doubt 等之 后。 ①They made an official request that the meeting be postphoned. 他们已经正式请求将会议推迟。 ②The problem whether we should continue to do the experiment has been solved. 我们是否应该继续做实验的问题已经解决了。 ③Where did you get the idea that I couldn't come. 你在哪儿听说我不能来？
3．从句中既不缺少成分，又语义完整，则用连接词that。 ①He gave us a suggestion that we should practise speaking English in class. (同位语从句，不缺成分和语义) 他建议我们在课堂上练习说英语。 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； 而what引导名词性从句时，在从句中要充当一定的句子成分。试比较： It's a shame that he has made such a mistake. 很遗憾他犯了这样一个错误。 I will do what I can （此处省略do）to help him. 我将尽力帮他。

高考英语语法复习名词性从句知识讲解讲义
高考英语语法复习名词性从句知识讲解一、与定语从句区别它们的性质不同，一个是名词，而另一个是形容词性。
名词性从句是独立的，而定语从句必须要依附先行词（相当于寄身虫）。
有时名词性从句可以转换成定语从句（必须加先行词）。
比如：What he said = The things that he said二、构成构成一个名词性从句就像是对一个陈述句进行特殊疑问句的提问，只不过不颠倒语序，如：He said something.What he said （名词性从句）What did he say? (特殊疑问句)三、分类（一）根据从句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四种。
（二）根据引导名词性从句的连接词可分为三类：1.连接词： that, whether, if （不充当从句的任何成分）2.连接代词：who, what, which, whose, whoever, whichever, whomever, whatever3.连接副词：where, when, why, how (how much, how long…), wherever, whenever, however1.主语从句【例句】1.That prices will go up is certain.= It is certain that prices will go up.2.How you travel means the difference between success and failure.3.Whether we go by train or by boat makes no difference.4.Who will write the poem has not been decided yet.5.What surprised us is that he lost in the game.6.What he left us was a large sum of money.7.When he will be back depends on the weather.8.Where we live doesn’t matter.9.How the pyramids were built was still a mystery.10.Watever he did is right.11.Whoever comes will be welcome.12.Whichever you want is yours.【注意点】That引导的主语从句中，that不能省略。
高中英语名词性从句精讲
高中英语名词性从句精讲从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。
在英语中,主要有三大从句,即名词性从句（包括主语从句,宾语从句,表语从句,同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
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。
引导名词性从句的连接词可分为三类：（1）从属连接：that, whether, if（不充当从句的任何成分）（2）连接代词：what, whatever, who, whoever, whom, whose, which.（3）连接副词：when, where, how, why名词性从句知识点汇总1名词性从句的分类名词性从句，包括四种从句，即主语从句、宾语从句、表语从句、同位语从句。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成，所以这四种从句在主句中都充当了名词的作用，故将这四种从句统称为名词性从句。
如：1.That she will help me made us happy.（主语从句）2.I can understand what he said.（宾语从句）3.This is where I was born.（表语从句）4.The fact that a heavy earthquake happened made me crazy.（同位語从句）2名词性从句的连接词分类1.that（无含义，不充当成分）2.whether,if（有“是否”的含义，但不充当成分）3.连接代词：what, whatever, who, whoever, whom, whomever, whose, which, whichever.（在从句中做主语、宾语、表语和定语）连接副词：when, whenever, where, wherever, how, however, why （在从句中做状语）4. as if,as though,because（不充当成分，在名词性从句中只引导表语从句）3连接词 that 在名词性从句中可以省略的三种情况1.it 做形式主语，that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。

That they are going to discuss at the meeting is how to increase food supply in the world.(错误)What they are going to discuss at the meeting is how to increase food supply in the world. (正确)注：that在引导名词性从句时本身没有意义，也不在从句中充当任何成分；而what则表示“什么”“……的东西或事情”，在从句中充当主语，宾语或表语等。
上句中的what 应充当discuss的宾语。
错误类型二：if 与whether的混用2. If we will visit the Great Wall tomorrow has not been decided yet. (错误) Whether we will visit the Great Wall tomorrow has not been decided yet. （正确）注：if 与whether 引导宾语从句时往往可换，但在下面情况时常使用whether：作介词的宾语时，见例①；在从句中提出两种选择时，见例②；从句提前时，见例③；引导主语从句，表语从句及同位语从句时，见例④。
①I worry about whether I hurt his feelings.②She wasn’t sure whether she should laugh or cry.③Whether he will come or not I don’t quite know.④What many people are worried about is whether we will be able to build a better future.We have some doubt whether they can complete the task on time.错误类型三：that 与because 的混用3. ⑴The reason why he was late for school was because he got up late.

(错误)That these old languages are now threatened and may disappear is a serious matter to the people in Britain. (正确)注：that在引导宾语从句时常常可省，但在下面情况时不可省去：宾语从句不止一个时，见例①；宾语从句与主句之间有插入语时，见例②；宾语从句为一个主从复合句时，见例③；引导主语从句，表语从句或同位语从句时，见例④。
①They complain (that) they have to work from morning till night, that it is hard to earn money, that they are bullied (欺负) by the policemen, or that the corporation leaders are seated lazily and enjoy the fruits of others’work.②The teacher said, pleasantly and firmly , that we must overcome the difficulties.③We believe that if we work harder, I will pass the National College Entrance Examination.④The trouble is that she has lost his address.

No matter who breaks the rules will be punished. (错误)Whoever breaks the rules will be punished. (正确)注：whoever,whatever,whichever,however,wherever等连词可以引导名词性从句也可引导让步状语从句，而no matter who\what\which\how\where…只能引导让步状语从句。
