Unit 2 Home Sweet Home Section A Grammar focus 课件 2025-2026学年人教版（2024）英语八年级上册

该初中英语课件聚焦情态动词could/can表请求与许可的用法，以歌曲《Hall of Fame》歌词导入，通过家庭、学校等真实生活场景的对话示例（如请求帮忙扫地、征求外出许可），逐步构建从语境感知到语法规则（Could/Can you please+V原...?等结构）的学习支架，帮助学生理解知识点脉络。 其亮点在于采用情境化与任务型教学，如设计“生活剧本杀”角色扮演、编对话等活动，结合语言能力（在真实情境中运用could/can交流）、思维品质（辨析请求与许可的用法差异）、学习能力（小组合作与实践操作）。学生通过分层作业（必做练习与选做视频任务）提升运用能力，教师可借助丰富示例与活动设计提高教学效率。
