Unit 1 Section Ⅲ Extended reading & Project & Assessment & Further study（课件PPT）-【精讲精练】2025-2026学年高中英语必修第三册（译林版）

该高中英语课件围绕“自然平衡”主题，系统梳理词汇（如recycle, defend）、短语（如in search of）、语法（如senior用法、倒装句）及语篇理解（如污染城市TV访谈），通过TV节目 transcript创设情境导入，以基础词汇落实为起点，衔接短语和语法搭建学习支架，递进至语篇分析，构建从词汇到语篇的完整学习脉络。 其亮点在于以真实语境（如污染城市访谈）和分层练习（随堂演练、课时作业）培养语言能力，结合文化意识（关注环境问题，体现人类命运共同体）与思维品质（通过词汇辨析、语法对比提升分析能力）。例如核心知识用“senior的三种表达”对比培养思维，学生能提升语境语言运用和逻辑思维，教师可借助结构化栏目高效实施教学。
