Module 12 Unit 3 Language in use课件2025-2026学年外研版(2012)英语九年级上册

该初中英语课件聚焦构词法（前缀后缀）和环保主题语言运用，通过“3R”（REDUCE, REUSE, RECYCLE）场景导入（如reduce的按需取食、关灯实例，recycle的卡通插图），借助单词组合任务（Box A+B词根词缀搭配）和猜词游戏搭建构词法学习支架，再过渡到环保建议讨论，形成从词汇到语用的连贯学习脉络。 其亮点在于构词法系统归纳与环保主题深度融合，通过任务驱动（如“full of hope→hopeful”猜词游戏）和情境学习（Earth Hour阅读、小组讨论可回收物品再利用），提升学生语言能力（词汇运用、环保建议表达）和思维品质（分析前缀后缀规则、比较系动词go与become区别）。学生在趣味活动中掌握构词规律，增强环保意识，教师可直接使用现成活动设计高效整合词汇、语法与主题教学。
