高中英语语法：名词性从句知识汇总
高中英语语法：名词性从句知识汇总在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。
因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。
当名词性从句要采用陈述句语序。
由一个含疑问意义的连词引起时，必须将该连词放在名词性从句的开头，且该从句语序不能倒装。
一、引导名词性从句的关联词引导名词性从句的关联词大致相同，它们分别是：连词：that, whether, if；关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever。
引导从句时一般不用逗号和主句分开。
连词that在从句中不作成分，不含疑问意义；而wh-连词在从句中作成分，且含有疑问意义；或what/where从句相当于一个名词后加一个定语从句。
It worried her a bit that her hair was turning grey.她的头发在变白令她有点担忧。
（that在从句中只起引导词作用，不作成分）What caused the accident is still a complete mystery.事故发生的原因仍然是个不解之谜。
（What在从句中作主语）2、that与whether引导名词性从句的区别。
（1）动词doubt表示“怀疑、不知道”解时，肯定句接whether引导的宾语从句；否定句don’t doubt和疑问句Do you doubt要接that引导的从句。
I don’t doubt that he will come soon.我不怀疑他不久会来。
（此处不用whether）Can you doubt that he will win?你怀疑他会赢吗？（此处不用whether）比较：doubt表示“不信”解时，表示强烈的不相信时，在陈述句中可接that从句。
