Unit1The Changing World SectionA 1a-2d 课件2026-2027学年人教版九年级英语上册

该初中英语课件围绕“家乡变化”核心主题，通过图片对比、问题链（如“How are these two photos different”）导入，衔接听力对话（1b电话交流、2a环境变化访谈）与过去-现在对比表格（交通、教育等），搭建从感知变化到分析变化的学习支架。 其亮点在于融合语言能力（听力理解与口语表达训练，如2d讨论问题解决）、思维品质（问题排序与原因分析，如“Rank the problems”）及学习能力（采访家人实践作业），采用任务型教学（填表、小组讨论），语法点（used to do等）系统归纳。学生能提升综合语言运用与逻辑思维，教师可借助结构化素材增强课堂互动。
