Unit 4 Section A (2a-2d) 课件 2025-2026学年人教版（2012）九年级英语全册

该初中英语课件围绕“used to”结构及其相关表达展开，系统设计了从热身导入、听力理解到语言输出的完整教学流程。通过对比人物过去与现在的变化，如Ke Nan戴眼镜变为不戴，Billy由害羞变开朗，构建清晰的学习支架，帮助学生在真实语境中掌握语法点和词汇用法。 其亮点在于融合语言能力、思维品质与学习能力培养，以对话情境为载体，引导学生分析人物性格转变，提升逻辑推理与价值判断力。例如，在2d阅读填空环节，学生需梳理Paula的变化并归纳原因，锻炼批判性思维。同时，通过句型操练与情景仿写，强化语言运用能力，促进自主学习习惯养成。此资料既助力学生精准掌握核心语法，又提升跨文化沟通意识，也为教师提供可直接使用的优质教学资源。
