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。
