Unit 5 Languages Around the World Discovering Useful Structures 课件-2025-2026学年高中英语人教版必修第一册

该高中英语课件聚焦定语从句，系统梳理关系代词（that/which/who等）、关系副词（when/where/why）、介词+关系代词及特殊先行词（如the way）的用法，通过结构地图搭建先行词、关系词、从句的逻辑框架，以“关系代词（表格归纳+填空练习）—关系副词（对比成分完整性判断）—拓展用法（抽象地点/介词选择）”为学习支架，帮助学生逐步构建知识体系。 其亮点在于融合结构化呈现（表格对比关系代词/副词的修饰对象与成分）、语篇实践（如“The Chinese Writing System”从句分析、完型语篇填空）及思维训练（通过从句成分分析推断关系词），助力提升学生语言运用能力与逻辑思维品质。采用“讲解—练习—应用”模式，学生在语篇分析与句子构建中强化语言能力，教师可借助系统练习与解析提高教学效率。
