名词性从句重难点剖析名词性从句包括主语从句、宾语从句、表语从句和同位语从句，高考常从连接词的选择、语序、语气、时态等方面来考查。

※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,whateverwhoever,whom,whose,which连接副词：when,where,how,why1、that和what都可以引导名词性从句，但that是连接词，本身无词义，仅起连接作用，不在从句中担任任何成份；what是连接代词，不仅引导名词性从句，而且在从句中充当一定的成份，如主语、宾语或表语。

例That he stole a bike was true. 他偷了一部自行车是真的。

The important thing is what you do, but not what you say. 重要的是你做什么，而不是说什么。

2、单个的主语从句作主语时，谓语动词用单数形式。

如果是两个或两个以上的主语从句作主语，谓语动词则用复数形式。

例Where and when he was born has not been found. 他出生在何时何地还不知道。

When the person was murdered and why he was murdered are still unknown. 那个人何时被谋杀，为什么被谋杀尚不知道。

3、在名词性从句中一律用陈述句的语序，即使从句表达的是疑问含义。

例The problem is what he has done to the little boy. 问题是他对那个小男孩做了些什么。

4、连接词that引导的主语从句放在句首时，that不能省略。

但为避免头重脚轻，可以用it作为形式主语，而把主语从句放到后面。

如果that引导的主语从句出现在疑问句中时，必须以it作形式主语而把主语从句后置。

例Is it true that the scientist will give us a lecture next week? 那个科学家下个星期给我们作报告是真的吗？5、宾语从句的谓语动词时态受主句谓语动词的影响，如果主句的谓语动词是一般现在时，从句中的谓语动词可以用各种时态；如果主句中的谓语动词用了一般过去时，则从句中的谓语动只能用过去时的某种形式，但如果从句表达的是客观真理或客观存在则不受此影响。
