高考英语语法完全讲解 名词性从句
定义及分类
在句中起到名词所能充当的句子成分的从句称之 为名词性从句，名词常用来作主语、宾语、表语、 同位语，因此，对应的名词性从句可以分为四大 类：主语从句、宾语从句、表语从句、同位语从 句。
主句从句
1、作句子主语的从句叫作主语从句。 2、为避免句子头重脚轻，常用形式主语it代替主语从 句，把主语从句置于句尾。常用的句型有：It is/was+ 形容词/名词/过去分词+that从句。
表语从句
位于系动词之后作表语的从句叫表语从句。 The problem is who is to pay and when we can start.
同位语从句
同位语从句说明其前面名词的具体内容。通常由that引 导，常接同位语从句的名词有：news, conclusion, possibility, rumor, certainty, story, word, mystery, idea, doubt, hope, truth, question, belief, fact, message, evidence, information, explanation, rule, probability, question, wish, thought, statement, report, opinion, principle等。
