2026-2027学年人教版英语九年级上学期Unit1 Section A（1a-1d）课堂逐字稿

该初中英语教学设计聚焦“used to+动词原形”结构及家乡变化的比较描述，通过1a中 Zhenbeitai 的今昔对比照片引导学生观察，自然过渡单元主题，结合30秒同伴分享社区小变化，搭建从生活观察到语言表达的学习支架。 资料亮点在于以视觉对比导入降低口语焦虑（语言能力），分层听力（1b短听力定位信息、1c长听力用Past-Present表格提取比较细节）提升信息提取效率（语言能力），结合环境问题讨论与生态意识培养（思维品质、文化意识）。使用音频、任务卡等教具，助力学生逻辑表达，为教师提供情境化分层教学方案。
