名词性从句考点+例题_全面解析经典

名词性从句名词性从句包括：主语从句、表语从句、宾语从句和同位语从句。

引导名词性从句的连词有：a.连词：that, whether, if（这三个词都不作从句的成分，同时，that无含义，而whether和if都表“是否”）b.疑问代词：who, whom, whose, what, whichc.疑问副词：when, where, why, how（一）主语从句在复合句中充当主语的从句。

1.that引导主语从句that引导主语从句时不同于其他的连词，既无词义也不作成分，只起单纯的连接作用，且通常不可以省。

为了强调that引导的主语从句而置之于句首时，that不可省。

①that the driver could not control his car was obvious.②that she was chosen made us very happy.③that he will come is certain.④that he would take the risk is true.⑤that he should have married her isn't surprising.★通常，that引导主语从句时用it做形式主语，把从句置于句尾，此时that有时可省。

例如：①it was obvious that the driver could not control his car.②it made us very happy that she was chosen.③it is certain that he will come.④it is true that he would take the risk.⑤it isn't surprising (that) he should have married her. ★如果以that从句为主语的句子是疑问句，就只能用先行词it结构。

高中英语名词性从句详细讲解与练习在句子中起名词作用的从句叫名词性从句。

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，因此根据它在句中不同的语法功能，名词性从句又可分为主语从句、宾语从句、表语从句、同位语从句。

引导名词性从句的词叫做连接词，包括：1.连词（在名词性从句中只起连接作用，不作成分）2.连接代词（在名词性从句中作主语、宾语或表语）3.连接副词（在名词性从句中作状语）所有的名词性从句的语序都是陈述语序。

I主语从句：是在主句中作主语的从句。

它由连接词引导，通常位于谓语动词之前。

连接词：1.连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether oThat he got the first prize excited him much.他获得一等奖一事使他非常兴奋。

It is doubtful whether we can get there on time.我们能否按时到达那儿还不确定。

D that引导的主语从句:在从句中不作任何成分，也没有实际意义。

一般情况下that不可省略。

That light travels in straight lines is known to all.众所周知，光沿直线传播。

That you don't like him is none of my business.你不喜欢他不关我的事。

2）whether引导的土语从句:常置于句首，表示“是否”之意；if一般不引导主语从句。

Whether he can finish his task on time is of greatimportance.他是否能按时完成任务非常重要。

Whether you can succeed or not depends on howhard you work at it.你能否成功取决于你努力的程度。

2.连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语,有具体意义且不能省略。

分析句子可知，主语从句中的lie为不及物动词，所以主句中缺少状语，因此填where。

expect sth.to do.固定短语，“期望某事发生”，sth. be expected to do.意为”某事有可能发生“。

make sth. clear to sb为固定搭配，意为“向某人阐明某事，使某人弄清某事”。

本句中make的宾语是where his failure lies 是被弄清楚，要用动词不定式的被动形式。

因此选C。

名词性从句讲解归纳及例题在主从复合句中，从句可以充当主句的主语、表语、宾语或同位语。

由于在多数情况下，主语、表语、宾语或同位语这四种句子成分由名词性词类充当，所以，我们把这些作用相当于名词的从句统称为名词性从句，把充当主语、表语、宾语或同位语的从句分别称为主语从句、表语从句、宾语从句或同位语从句。

也就是说充当什么成分就叫什么从句。

名词性从句由连接词（或关联词）引导。

常用的连接词有：注意：1.它们的特点是：1、疑问词有本身的词义；2、疑问词在从句中担当句子成分，如主语、宾语或状语；3、这种疑问词引导的从句一律用陈述语序，不能用疑问语序。

Do you know whom they are looking for?I don’t know who did it.She asked me where I had been.Can you tell me when the train will arrive?I don’t know why he hasn’t come yet.He didn’t tell me what you were doing.What you have done might do harm t other people.I don’t know where he is now.Where he went for his weekend is not known.What I want to know is where he has gone for his weekend. 2.做名词性从句的题的三大步：一分，二划，三看，即一分句子结构，二划从句类型，三看句意完整否。

下面我们再分别讲述主语从句、宾语从句、同位语从句和表语从句。

一、主语从句1．that 引导主语从句时，that 没有意义，但不能省略。
