Unit 1 Lesson 2 Section A (2a-2d) （讲解课件）-【优翼·学练优】2026-2027学年九年级英语上册同步备课（人教版·新教材）

该初中英语课件围绕“环境问题及解决方案”展开，通过“Look and Say”图片识别（如沙尘暴、耕地短缺）、问题影响讨论（如呼吸困难、粮食短缺）及排序阐述理由，搭建从认知到分析的学习支架，衔接后续听力任务。 其亮点在于融合语言能力（听力提取对话中环境问题与解决方案）、思维品质（问题排序及“变化-原因”逻辑分析）和文化意识（联系现实环保），采用角色扮演、表格填空等活动，以箭头流程梳理“种植灌木→减少沙尘暴→改善生活”逻辑。学生能提升语言运用与批判性思维，教师可获得结构化教学资源支持。
