√√√考法总结考查内容：名词性从句是高考考查的重点和热点，命题方式非常灵活：
1.把它与定语从句和状语从句的知识点放在一起进行考查，对名词性从句的考查主要涉及语序问题、时态的呼应问题和连接词的选择问题，尤其是that和what的辨析。whether和if的用法区别。
2.题干语境越来越多样，句子结构也越来越复杂，命题人侧重于对复杂句子结构的考查，这是因为分析复杂句子的结构是掌握英语这门语言的重要能力之一。热点预测2018年高考将继续侧重对名词性从句中连接词的考查，其中，what与whether, who和whoever, where, that将是考查的重点。注重对从属连词、连接代词、连接副词、关系代词及关系副词的混合考查。
