教材分析

本课教学内容选自高等教育出版社出版的“十四五”职业教育国家规划教材，《英语3 基础模块》中第七单元的Language Practice板块，内容为主语从句、表语从句和本单元的重点词汇。通过任务呈现、训练和应用语法三个阶段，帮助学生理解、掌握较为完整的主语从句和表语从句的语法体系，培养学生的探究能力和具体语境中的语法应用能力。词汇训练均为本单元的核心词汇，学生通过在具体语境中运用单词和短语，巩固本单元重点词汇的学习，达到真正运用的目的。

学情分析

学生已经对宾语从句进行了系统学习，大部分学生能辨别此类从句的结构，关系词用法，语序和时态等要素。但很多学生在理解主语从句和表语从句方面仍存在一定的困难，对表语、系动词、关系词的用法不熟悉，对表语从句引导词的具体使用和表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，运用旧有知识过渡，归类名词性从句总结，最终达到灵活运用和掌握主语从句和表语从句的教学目标。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。
