Unit 2A green life 第3课时 Speed up（课件）-2026-2027学年外研版（三起）英语五年级上册

该小学英语课件围绕“牛奶盒回收”核心主题，涵盖信件逻辑理解、回收三步法（打开清洗、压平、放入回收箱）及环保践行。课堂通过“日常喝牛奶及处理方式”问题导入，以502班信件为载体，逐步学习牛奶盒材质（纸、塑料、金属）与再利用知识，结合思维导图梳理内容，搭建生活到实践的学习支架。 其亮点在于融合生活化情境与多元活动，通过“Think and answer”引导思考（思维品质），“Listen and repeat”提升语言表达（语言能力），思维导图整合材质、步骤与再利用价值，视频辅助直观理解。培养学生环保意识（文化意识），实践作业促进知识应用，教师可借助结构化资源提升教学效率。
