Unit 4 Reduce, Reuse, Recycle Project课件2026-2027学年人教版九年级英语下册

该初中英语课件围绕“Reduce, Reuse, Recycle”核心主题，通过观看视频识别水污染、噪音污染等污染类型，引出三R环保理念，搭建从问题意识到解决方案的学习支架，帮助学生系统掌握环保实践方法。 其亮点在于采用项目式学习，以小组合作设计传单为主线，融合语言能力（用“I think we can reduce waste by...”等句型交流）、学习能力（任务分工与合作）和思维品质（评价表分析内容与语言）。例如学生先列举日常三R做法，再小组讨论选优制作传单，既提升环保责任感，又帮助教师高效落实核心素养目标。
