Unit 1 Section A (1a～2d) 课件2026-2027学年人教版英语九年级上册

该初中英语课件围绕“家乡变迁”主题，涵盖核心词汇（如sandstorm、be covered with）、听力提取对比信息技能及used to do等语法点。课堂导入通过Free talk（身边10年变化）和图片讨论（Li Rui家乡变迁）激活经验，结合音频材料引导学生听电话对话、填写过去与现在对比表格，搭建从感知到分析的学习支架。 其亮点在于任务驱动的探究式学习，通过听力材料（电话对话、祖孙对话）培养语言能力（提取信息、总结原因），分析环境问题及解决措施（种植灌木固土、政府支持）提升思维品质，渗透热爱家乡的文化意识。语法总结清晰（如used to do三种句式），评价题（填空、短文盲填）巩固知识。学生提升语言运用与思维能力，教师获得结构化资源，提高教学效率。
