Unit 4 Helping in the community Part B Let's talk（课件 ）-2025-2026学年人教PEP版英语四年级上册

该小学英语课件围绕“社区帮助”主题，聚焦现在进行时（结构及动词现在分词变化规则），通过“老人之家”情境导入，以提问讨论激活已知，呈现学生铺床、唱歌等活动作为语言输入，构建“情境感知-语言学习-规则总结-实践运用”的学习支架。 其亮点在于情境化与游戏化结合，借助视频播放、角色扮演提升语言能力，“职业-动作-地点”趣味搭配（如“A cook is singing at the bus stop”）培养思维灵活性，动词分词规则引导学生自主归纳发展学习能力。学生能在互动中掌握语法，增强社会责任感，教师可直接用多样化活动提升教学效率。
