如何突破名词性从句？第一步　识别名词性从句的种类1.首先确定主句的谓语动词，确定主句的主谓结构；2.分析从句在主句中所充当的成分，确定从句所属类型：主语从句、宾语从句、表语从句、同位语从句。
第二步　分析从句结构，确定从句引导词确定从句的结构和意义是否完整，结合句意填写适当的连接词。1.若从句结构完整，用从属连词：陈述事实用that；表示疑问“是否”用if或whether；2.若从句缺少主语、宾语、表语或定语，则考虑用连接代词；3.若从句缺少状语，则用连接副词。另外，还需注意一些特殊的引导词(if、whether、because、as if等)的用法及that引导同位语从句与定语从句的区别。
