Unit 2 Home Sweet Home Section A (3a–3c)教学设计
课题名称 Unit 2 Home Sweet Home — Section A (3a–3c) （Grammar Focus：情态动词 can / could 表请求与许可） 课型 语法课
设计者 Mary 计划课时 1课时
学习目标 ① 能够在不同生活场景中，精准识别 can / could 表请求和许可的语义，清晰梳理 3a 中问答的语言功能，理解不同情境下 can / could 的表意逻辑；（学习理解）
② 能够结合不同情境，熟练使用 can / could 完成对话补全与创编，遵循语法规则且契合生活交流逻辑，实现有效互动；（应用实践）
③ 能够迁移 can / could 表请求、许可的用法，自主创设新生活情境（如校园求助、家庭活动协商等），用英语开展真实交流，体现语言服务生活的育人价值。（迁移创新）
学习重点 能够识别 can / could 在请求和许可语境中的语义差异，区分“向对方提出请求（Can/Could you... ）”与“请求对方允许自己做某事（Can/Could I... ）”，并清晰梳理 3a 中问答的语言功能。 学习难点 能够在不同生活情境中，用 can / could 礼貌地提出请求、征求许可并恰当回应，进而结合真实场景创编对话，实现有效交际。
核心问题 如何区分并正确使用 can / could 提出请求（Can/Could you please... ）与征求许可（Can/Could I... ），并在真实生活情境中礼貌回应？
教学流程
学习内容 教师活动 学生活动 伴随评价
Lead-in 家庭情境图，感知请求指令 任务一：情境导入（Lead-in）
呈现家庭情境图，引导看图听读 "Pack up your things." "Sweep the floor." 等指令句，初步感知真实情境中的请求表达。 看图、听音，说出图中人物发出的指令，感知请求语境。 观察学生能否理解并说出图中的指令句。
创设生活情境，体验 can / could 表请求与许可 任务二：呈现感知（Presentation）
呈现 4 个真实情境（手机没电借手机、借课堂笔记、帮忙开门、请带手套清理社区），示范 "Can/Could I... "（征求许可）与 "Can/Could you... "（提出请求）的问答。 结合情境仿说对话，区分“征求许可（I）”与“提出请求（you）”两种句式。 学生能否用 can / could 正确提问并礼貌回应。
读 3a 对话，归纳 can / could 用法，区分请求与许可 任务三：归纳发现（3a–3b）
引导学生读 3a、观察共性（以 can/could 开头＋动词原形＋疑问句），讲解 "Could you please... " 提出请求、"Can/Could I... " 征求许可，以及回答用 could 提问的请求时通常用 can。 小组合作分析例句，判断请求（R）/许可（P），归纳规则并完成 3b 对话补全。 检查学生的总结分析能力及语用区分能力。
基于生活情境用 can / could 创编对话 任务四：实践创编（Practice & Group work）
组织学生就 4 个情境创编对话，开展小组任务（班级大扫除任务分工），巡视指导并纠正语用。 个人 / 小组用 can / could 创编对话，在组内展示交流。 学生能否用 can / could 进行有效口头交际。
当堂检测与课堂总结 任务五：检测总结（Exercises & Summary）
组织完成练习题（选择、词形填空），归纳总结 requests 与 permission 的核心句式。 独立完成练习、核对答案，回顾总结 can / could 的用法。 通过习题检测学生掌握程度，及时反馈矫正。
分层作业 基础作业：背诵 3a 对话，用 5 个生词（如 until、dead、note 等）各造 1 个句子。 提升作业：结合学校生活，编写 2 组向同学或老师发出请求 / 征求许可的对话。 扩展作业：策划“新家乔迁派对”的准备工作，用 can / could 就筹备事项发出请求或征求许可。
