Unit13 We‘re trying to save the earth! SectionA 1a～1c课件 -2025-2026学年人教版（2012）英语九年级全一册

该初中英语课件围绕“污染与环境保护”主题，通过图片描述（如飞机低空飞行、车辆废气等污染场景）和听力对话（Tony与Mark讨论河流污染）导入，引导学生分类学习噪声、空气、水污染的类型、原因及解决措施，构建从现象到原因再到解决方法的学习支架。 其亮点在于融合语言能力与思维品质培养，通过听力填空、对话练习提升语言理解与表达，通过分析污染原因（如工厂排污、乱扔垃圾）和解决措施（写信给政府、清理河流）锻炼问题解决思维。采用图片直观呈现、小组竞赛等互动形式，既增强词汇记忆（如litter, close down），又激发环保意识，学生能在真实语境中运用语言，教师可直接利用多样化活动提升课堂效率。
