Unit 1 Section B 1a～1f 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“变化的世界”主题，聚焦蒙内铁路阅读文本，通过寻读提取数字信息、预测理解脉络等策略，引导学生运用used to等核心句式复述故事。课堂导入从城市交通变化切入，结合中国火车发展四阶段（早期、重建自制、提速、高铁时代）的Free Talk活动，搭建从国内到国际的知识支架，自然衔接蒙内铁路主题。 其亮点在于以蒙内铁路为载体，融合文化意识与思维品质培养，通过对比旧铁路与新铁路的差异，分析因果关系并推断“on the fast track”的深层含义，增强学生人类命运共同体意识。采用任务型阅读（预测、略读）和图表整合信息等方法，学生能提升阅读策略与跨文化理解能力，教师可借助结构化活动设计高效开展教学。
