Unit 1 The Changing World Section A 1a-1d 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“谈论事物与过去的变化、影响及原因”核心知识点，通过“Look and share”环节对比干旱与绿色的照片引导学生观察变化，再分交通、住房等具体方面提问，搭建从图片观察到话题讨论的学习支架。 其亮点在于融合语言能力、思维品质和学习能力培养，通过音频对话（如Li Rui与George讨论家乡20年变化）训练听力，对比“used to...”“Now...”句型提升表达，小组讨论变化原因（政府支持、人们努力）培养探究能力。学生能在真实语境中运用语法，教师可借助结构化活动高效教学。
