Unit 13 We're trying to save the earth！ Section A 1a-1c 课件 2025-2026学年人教版英语九年级全册

该初中英语课件围绕“环境保护”主题，聚焦污染类型（水污染、空气污染、噪音污染）、成因及解决办法，结合相关词汇（litter, bottom等）和句型（try to do sth.等），通过问题链（地球变丑的原因→污染类型→成因分析）导入，以词汇分类（1a）、听力音频（1b）、对话角色扮演（1c）为支架，构建“词汇-输入-输出”的学习脉络。 其亮点在于融合语言能力、思维品质与学习能力培养，通过任务链（词汇分类→听力理解→对话输出）提升语言表达与理解能力，问题讨论（如污染成因分析）培养分析和创造思维，学习方法建议（如翻译歌词、合理规划）助力学习策略形成。实例包括1a词汇匹配活动、1c对话框架练习，学生能在真实情境中运用语言，教师可借助结构化任务提高教学效率。
