Unit2 Home Sweet Home SectionA Grammar Focus（教学设计）-2025-2026学年八年级英语上册（人教版）

2026年道县优质教学资源评选活动 ---八年级上册Unit2 Home Sweet Home 语法课教学设计 课程基本信息 主备人 蒋娅莲 课型 新授课 学科 英语 年级 八年级 学段 初中 版本章节 人教版 教学目标 在本课学习结束时，学生能够： 1.understand the differences between “can” and “could” for requests and permissions. (学习理解) 2.use “can” and “could” correctly in exercises. (应用实践) 3.use them in real - life conversations, like asking for help. (迁移创新) 教学重难点 教学重点： 1.区分 “can” 和 “could” 在请求与许可场景中的用法，掌握核心句型 “Can/Could you (please) do sth.?” 和 “Can/Could I do sth.?”。 2.正确运用两种句型的答语，尤其是否定答语的礼貌表达（如 “Sorry, I can't. I have to...”）。 教学难点： 1.灵活运用 “can” 和 “could” 根据场景调整语气（如正式场合用 “could” 更礼貌，日常熟悉场景可用 “can”）。 2.避免 “用 could 回答 could 提问” 的常见错误，牢记 “提问用 could，回答用 can” 的规则。 学情分析 学生已在前两课时接触过can/could的基本用法，但对两者在礼貌程度上的差异及答语规则（如用can回应could提问）掌握不清晰。在实际运用中，学生易混淆请求与许可的句型。教学中需通过情景对比和专项练习强化认知，结合生活场景提升运用灵活性。 教学准备 PPT、翻页笔、教材等 教学过程 Step1.Warm-up Teaching Steps: The teacher shows the video and pictures of a “housewarming party” and asks in English: “Do you know what party this is? Have you ever been to a housewarming party? What do people usually do at such a party?” Guide students to answer in simple English, then transition: “Today we’ll learn how to use ‘can’ and ‘could’ to ask for help or permission at a housewarming party.” 设计意图：以“乔迁派对”这一贴近学生生活的场景为切入点，借助图片和问题激活学生的生活经验与英语表达意愿，降低语法学习的陌生感。同时直接点明本节课主题，让学生清晰明确学习目标，为后续教学内容做好铺垫。 Step2. Presentation (学习理解) 1. 情景呈现：乔迁派对准备（Preparation） Teaching Steps: The teacher presents dialogue pictures of four sub-scenarios in sequence (e.g., “Asking to put flowers”, “Asking to go out”, “Asking for help to hang photos”, “Asking to sweep the floor”). Guide students to read the dialogues group by group and observe the differences in the usage scenarios and responses of “can” and “could”. 设计意图：通过具象化的对话图片，将抽象的语法规则转化为 “可感知、可朗读” 的具体语境，让学生直观感受 “can” 和 “could” 在语气（委婉程度）、功能（请求 / 许可）上的区别，符合八年级学生 “从具体到抽象” 的认知规律，帮助学生初步建立对语法知识的认知。 2. 对话匹配（Read and match） Teaching Steps: The teacher presents two groups of sentences (one group for “asking permission” and the other for “making polite requests”). Students complete the matching independently, check with their deskmates, and then the whole class checks the answers together. The teacher explains the sentences with more mistakes. 设计意图：该练习聚焦 “句型功能区分”，是语法应用的基础环节。通过 “独立完成 + 同桌互查” 的形式，既能让学生自主检验对 “请求 / 许可” 句型的理解程度，又能通过同伴互助及时纠正错误，为后续更复杂的练习打下坚实基础。 3. 归纳总结与歌曲复习 Teaching Steps: Guided Questions: “What’s the difference between ‘can’ and ‘could’? When do we use ‘Can/Could I...?’ and ‘Can/Could you...?’”. Organize students to discuss in groups and share their ideas. Teachers and students jointly summarize the rules that “could is more polite”, “Can/Could I... is for permission”, and “Can/Could you... is for requests”, and write the mnemonic “Ask others for requests; ask for yourself for permission” on the blackboard. Song Review: Play the adapted “dialogue song” and let students sing along with the core dialogues (e.g., “Could you please sweep the floor? Yes, Dad. I’ll do it at once.”). 设计意图：通过 “提问 - 讨论 - 总结” 的过程，引导学生自主归纳语法规则，避免教师 “满堂灌” 的教学模式，培养学生的逻辑思维能力和自主学习能力。“小口诀” 简洁易记，能帮助学生快速掌握句型功能；歌曲则能活跃课堂氛围，将枯燥的语法记忆转化为轻松的听觉体验，强化核心句型的记忆效果。 Step3.Practice (应用实践) 1. 练习 1：补全对话（3b） Teaching Steps: Show the scenario of “welcoming guests to the new house”, present 4 incomplete dialogues and options A-D (e.g., “Asking for help to move a chair”, “Asking to stay up late”). Students choose options to complete the dialogues according to the logic of the responses (e.g., “Of course you can. Let me show you the way.” corresponds to “asking to use the toilet”). Then invite students to read the complete dialogues, and the teacher corrects their pronunciation and tone. 设计意图：从 “单一句型匹配” 过渡到 “完整对话补全”，练习难度逐步提升，考查学生 “根据语境选择合适句型” 的综合应用能力。让学生朗读对话，既能训练口语表达能力，又能让教师直观了解学生对 “could” 委婉语气的把握程度，及时调整教学重点和节奏。 2. 练习 2：创编对话（3c） Teaching Steps: Present 4 real-life scenarios (e.g., “Borrowing a phone to make a call”, “Borrowing party photos”, “Asking for help to open the door”, “Asking to bring cleaning tools”). Students discuss in groups and create dialogues containing “can/could”. Each group selects a pair of representatives to present their dialogues. The teacher comments on “correctness of sentence patterns”, “appropriateness of tone”, and “fluency of expression”. 设计意图：通过 “分组创编” 的活动形式，让学生从 “被动做题” 转向 “主动运用”，培养语言输出能力和创新思维。场景贴近生活，能让学生感受到语法知识的实用价值，激发学习兴趣；小组合作和展示环节，还能增强学生的团队意识和英语表达自信心。 Step4. Production (迁移创新) 结对练习（Pair-work） Teaching Steps: Create the scenario of “cleaning the room after the party”. Ask students to work in pairs to create dialogues using “Could/Can I...?” and “Could/Can you...?” (which should include both affirmative and negative responses, e.g., “A: Could you help me take out the rubbish? B: Sure. But I need to finish cleaning the table first.”). After students have a free dialogue, the teacher takes photos to show excellent dialogues and comments on them. 设计意图：“派对后打扫” 是 “乔迁派对” 场景的自然延伸，语境连贯且真实，能帮助学生更好地融入场景进行语言实践。要求包含 “否定答语”，能针对性解决学生 “只会用肯定答语” 的问题，完善语言应用能力。拍照展示优秀对话，既能激励学生积极参与，又能为其他学生提供可借鉴的范例，实现 “以优带差” 的教学效果。 Step5. Further thinking Teaching Steps: The teacher asks: “Why do we need to use polite requests and ask for permission in daily life?” Guide students to speak freely, then summarize the benefits of polite language (showing good manners, building good relationships, getting positive responses), and ask students to give examples of “how to communicate politely with 'can/could' at home or school”. 设计意图：从 “语法应用” 上升到 “情感价值” 层面，让学生不仅学会 “怎么用”，更理解 “为什么要用”，实现 “语言能力” 与 “文化意识” 的同步培养。让学生结合自身生活举例，能将语法知识真正迁移到日常交流中，达成 “学以致用” 的教学目标，同时培养学生的文明交际素养。 Step6.Summary Teaching Steps: Teachers and students jointly sort out the core content of this lesson in the form of a table (sentence pattern, usage, response, precautions). Then students complete the “Self-assessment” and score themselves (1-5 points) from three dimensions: “understanding differences”, “doing exercises correctly”, and “having real dialogues”. They also share their learning gains and shortcomings. 设计意图：表格形式清晰直观，帮助学生系统回顾本节课知识点，形成完整的知识框架，避免知识碎片化。“自我评估”能让学生主动反思学习效果，明确自身不足，培养自主学习能力和反思意识。分享环节则能让教师及时了解学生的学习反馈，为后续教学调整提供参考依据。 Step7. Homework Must-do: Create at least 3 groups of dialogues, including “polite requests (Can/Could you...?)” and “asking for permission (Can/Could I...?)”, and each group of dialogues must have complete responses. Choose to do: Observe the scenarios of “requests and permissions” at home, record 3 examples in English, and analyze the usage differences between “can” and “could” in them. 设计意图：采用 “必做 + 选做” 的分层作业形式，既保证所有学生都能巩固核心知识点（必做部分），又为学有余力的学生提供拓展空间（选做部分），兼顾学生的个体差异，实现 “因材施教”。选做作业要求 “观察家庭场景”，能进一步推动语法知识与生活实际的结合，实现 “课内外联动”，让语法学习延伸到生活中。 板书设计/课堂小结 Unit 2 Home Sweet Home Section A Grammar Focus 教学反思 本节课以主题语境引领、核心素养导向，围绕 can/could 表请求与许可开展语法教学，基本达成学习理解、应用实践、迁移创新的教学目标。本课以 “乔迁派对” 为主线，将语法融入真实情境，遵循 “输入 — 操练 — 输出” 设计活动，借助口诀降低认知难度，注重礼貌用语与文明礼仪渗透，实现语言能力与文化意识协同发展。同时采用自评、分层作业等方式关注学生差异，课堂参与度较高。 教学中仍存在不足：学生自主探究空间不足，教师归纳偏多；对 “could 提问、can 回答” 易错点强化不够；时间分配与个体指导有待优化；语境拓展较单一，跨场景迁移训练不足。 今后将优化课堂结构，突出学生主体，增加自主归纳与专项纠错训练，提供句型支架帮扶学困生；拓宽校园、公共场合等真实语境，强化真实语用输出，让语法教学更精准、高效。 — - 1 - — 学科网（北京）股份有限公司 $
