Unit 1 Section A 1a-2d 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”主题，核心知识点包括谈论过去与现在的差异、分析变化影响及原因，语法聚焦一般过去时与现在完成时的对比运用。课堂通过“Look and share”看图提问、“Time Traveler”找不同游戏导入，搭建从观察到表达的学习支架，衔接听力理解与语法对比练习。 其亮点在于融合多模态活动提升核心素养，如“1d Logic Salon”引导学生讨论变化原因，培养思维品质中的分析与推断能力，“Memory Master”游戏用关键词复述强化语言能力。语法通过时间轴对比两种时态，直观呈现“过去完成”与“持续影响”的区别。学生能在实践中提升语言运用与问题解决能力，教师可借助丰富活动设计优化课堂互动与教学效果。
