1、名词性从句专项一、知识梳理/提炼要点一：句子的分类根据句子的结构可分为： 简单句一主一谓。并列句由等立连词and, but, so, for把两个（以上）的简单句连在一起构成。复合句一个主句+从句（一个或以上）构成。根据从句在复合句中的作用，分为名词性从句、定语从句和状语从句。名词性从句包括主语从句、表语从句、宾语从句、同位语从句。要点二：名词性从句总述1. 主语从句在句中作主语，可用it作形式主语，把真正的从句放在句尾。如：It is still a mystery how the prisoner escaped.犯人是如何逃跑的是个谜。主语从句中 ，谓语动词一般用单数。What引导的主语
2、从句，可根据表语决定。如：What he needs is that book?What he needs are some book?主语从句常用的结构有：It is well known/reported/thought/said/ thatIt is natural/surprising/necessary/certain/true/clear thatIt is a pity/a shame/an honor/no surprise/no wonder thatIt doesntt matter whetherIt seemsappears that It happens that2.
