Unit 4 Friends forever Using language 定语从句入门 课件-2026-2027学年高中英语外研版必修第一册

该高中英语课件聚焦定语从句核心知识点，涵盖关系代词（who/which/that）与关系副词（when/where/why）的用法。课堂导入以“王者峡谷”情境为载体，从形容词作定语（名前系后）过渡到简单句合并，搭建由旧知（形容词定语）到新知（定语从句）的学习支架，清晰呈现知识脉络。 其亮点在于采用情境化与渐进式教学法，结合“王者峡谷”角色描述实例（如“He is a handsome guy who has a long sword”），通过错误与正确合并对比分析引导词作用，培养学生思维品质（分析、推断）与语言能力（理解表达）。练习设计针对性强，助力学生高效掌握语法规则，教师可直接用于课堂提升教学效果。
