教材分析 本节课的主要内容为基础模块3Unit7 Natural Disasters Language Practice板块，针对z主语从句。语法活动分为呈导入、呈现、练习三个阶段，帮助学生理解、掌握主语从句的用法，强调学生的探究能力、在具体语境中的应用能力。
学情分析 学生通过前面宾语从句的系统学习，大部分学生已经掌握了此类从句的结构，关系词用法，语序和时态等要素。同时，很多学生在理解主语从句方面还存在一定的困难，对主语从句引导词的具体使用和主语从句的实际运用方面还需要进一步的学习和练习。在本课教学中，教师还应有意识的引导学生梳理名词性从句的学习思路，构建句法体系，搭建知识结构，并理解它们的内在联系，从而能更准确地运用。对于词汇学习，教师要注意情景创设，帮助学生掌握词汇的具体用法。
