Unit 1 The Changing World Section A 1a-1d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“家乡变化”核心主题，涵盖交通、医疗、购物、环境等方面的过去与现在对比。课堂导入通过“Look and share”活动，引导学生观察新旧照片差异、变化及原因，搭建从直观感知到语言表达的学习支架，衔接词汇预习（拆分、词根等记忆法）与新知学习（听力对话、表格填写、讨论）。 其亮点在于多模态输入输出结合，通过图片对比、听力材料（1b电话交谈、1c参观对话）、表格梳理（1c过去现在对比）、讨论（1d变化原因）等，培养语言能力（听力理解、口语表达）和思维品质（对比分析、逻辑推断）。小结按主题分类整合知识，分层作业（A层默写巩固、B层拓展写作口语）兼顾差异。助力学生提升语言运用与逻辑思维，教师可高效实施分层教学。
