学情分析 八年级学生已在本单元Section A学习了Can/Could you please... 礼貌请求句型，具备一定的家务和家居类词汇基础。本课时阅读文本为Zhang Peng写给朋友的求助邮件，涉及房间装饰主题，学生在理解邮件组织逻辑和礼貌用语方面需要策略引导；3c写作要求仿写一封求助邮件，学生在邮件格式、内容组织和礼貌表达上易出错，需要通过范文分析、排序练习和仿写框架进行突破。
教学目标 ①语言能力：能阅读并理解3a中Zhang Peng写给朋友的求助邮件，提取关键信息（求助内容、计划安排、物品需求）；能分析邮件的组织逻辑并完成3b排序任务；能运用Can/Could you please... 等礼貌句型完成3c求助邮件写作。②学习能力：通过3a阅读提取→3b逻辑排序→3c仿写邮件的读写结合策略，培养信息提取与书面表达能力。③思维品质：通过分析邮件内容的组织结构，培养逻辑分析与归纳思维能力。④文化意识：理解对生活环境美化的需求，增强对生活美学的关注，体会英语在跨文化日常交流中的应用价值。
教学重难点 重点：掌握6个核心词汇（decorate, cover, poster, scissors, glue, paper-cut）；理解求助邮件的组织结构（开篇请求→描述现状→具体计划→征求意见）；运用Can/Could you please... 和What do you think about... 等礼貌表达写邮件。难点：邮件内容的组织逻辑和连贯性；礼貌请求的表达方式和语气把握；在写作中恰当运用本单元核心词汇和句型。
教学过程
Step 1 Warm-up 情境导入（3~5 min）
【教师活动】用亲切的语气温和导入本课主题：T: Good morning, everyone! Do you like your room Do you want to decorate it Today we will read an email about decorating a room. First, let's talk about your room. What do you have in your room 教师引导学生用英语描述自己的房间物品，激活已有词汇。
【学生活动】Ss: 根据教师提问思考并描述自己的房间，用句型 'I have ... in my room.' 或 'There is/are ... in my room.' 进行回答。学生活动示例：S1: I have a desk and a chair in my room. S2: There are some photos on the wall. S3: I want to decorate my room with some posters. 2-3名学生分享，其余学生认真倾听并记录同伴提到的物品名称。
【教师活动】教师板书核心词汇decorate并领读：T: Look at this word — decorate. It means 装饰；装潢。 Read after me: decorate / dek re t/. 教师追问：What can we use to decorate a room 引导学生说出poster, photo, paper cutting等词汇。
【学生活动】Ss: 跟读decorate三遍，注意发音。学生思考并回答教师提问：We can use posters, photos, paper cuttings, flowers... 学生在课本p.19标题处标注decorate的音标和释义。
【提示框】理解要点：读写结合课教学策略
本课时采用'阅读输入→分析结构→仿写输出'的读写结合策略：3a先阅读范文邮件（提取关键信息），再通过3b排序理解邮件组织逻辑，最后用3c仿写求助邮件（格式规范、逻辑清晰、用语礼貌）。这种从输入到输出、从理解到运用的策略有助于突破写作难点。
【过渡语】【过渡语】Zhang Peng and his brother want to decorate their room. Let's see what he writes to his friend.
Step 2 Presentation 知识呈现（10~15 min）
2.1 Look and say 看图说话（3 min）
【教师活动】展示Zhang Peng和弟弟的房间图片，引导学生观察并思考：T: Look at this room. This is Zhang Peng and his brother's room. They want to decorate it. What do you see in the room What do they need to decorate it 教师引导学生用英语描述房间现状和装饰需求。
【学生活动】Ss: 观察图片，思考并回答教师提问。学生活动示例：S1: I see a bed, a desk, and some boxes. S2: The walls are white. They need some colors. S3: They need paint, brushes, and posters.
【教师活动】教师适时引出本课情境：T: Zhang Peng wants his friend John to help him, so he sent an email to John. Let's read the email together. 教师引导学生预测邮件内容：What do you think Zhang Peng asks John to do
【学生活动】Ss: 根据情境预测邮件内容。学生活动示例：Maybe he asks John to buy paint. / Maybe he asks John to help hang posters. 学生快速浏览3a邮件，验证自己的预测。
Zhang Peng和弟弟的房间
【过渡语】【过渡语】Let's read the email and find out what Zhang Peng asks his friend to do.
2.2 3a 阅读求助邮件（7~8 min）
【教师活动】布置3a阅读任务：T: Now open your books to page 19. Read the email and find out what Zhang Peng asks his friend to do. 教师引导学生快速阅读邮件，提取关键信息，限时3分钟。教师提示阅读策略：关注邮件开头的主要请求、中间的现状描述和计划、结尾的见面安排。
【学生活动】Ss: 独立阅读3a邮件文本，用笔划出Zhang Peng请求John做的事情。学生活动示例：圈出help decorate the room, share ideas about the wall color, choose the paint, paint the room, bring the brushes, choose some photos等关键信息。完成后与同桌核对答案。
【教师活动】阅读后核对答案：T: What does Zhang Peng ask John to do 教师板书并领读核心词汇：decorate / dek re t/ v.装饰；装潢, cover / k v (r)/ v.遮盖；包括 n.遮盖物；封皮, poster / p st (r)/ n.海报, scissors / s z z/ n.剪刀, glue /ɡlu / n.胶水 v.粘贴, paper-cut / pe p (r)k t/ n.剪纸。教师讲解邮件大意：Zhang Peng想请John帮忙装饰房间，包括选墙漆、买油漆、刷墙、带刷子、选照片等。
【学生活动】Ss: 1-2名学生口头汇报Zhang Peng的请求事项，其余学生补充。学生活动示例：在课本上标注6个核心词汇的音标和释义，并跟读decorate, cover, poster, scissors, glue, paper-cut。
3a求助邮件阅读任务
【知识点】核心词汇6个：decorate / dek re t/ v.装饰；装潢 | cover / k v (r)/ v.遮盖；包括 n.遮盖物；封皮 | poster / p st (r)/ n.海报 | scissors / s z z/ n.(pl.)剪刀 | glue /ɡlu / n.胶水 v.粘贴 | paper-cut / pe p (r)k t/ n.剪纸。
【知识点】邮件阅读策略：快速浏览抓主旨（Zhang Peng请John帮忙装饰房间）→ 细读提取具体请求（share ideas, choose paint, paint room, bring brushes, choose photos）→ 分析组织结构（开篇请求→现状描述→具体计划→征求意见）。
【提示框】易错提示：scissors的用法
scissors / s z z/ 意为'剪刀'，通常以复数形式出现，动词也用复数。如：The scissors are on the table.（剪刀在桌子上。）表示'一把剪刀'时用a pair of scissors。如：Could you bring a pair of scissors （你能带一把剪刀吗？）类似的词还有glasses（眼镜）、trousers（裤子）等。
【提示框】重点强调：bring与take的区别
bring表示'带来'（从别处带到说话人所在处），take表示'带走'（从说话人所在处带到别处）。例句：Could you bring the brushes to my house （你能把刷子带到我家来吗？）Please take the rubbish out.（请把垃圾拿出去。）本课邮件中Zhang Peng请John bring the brushes，是让John把刷子带来。
【过渡语】【过渡语】We know what Zhang Peng asks John to do. Now let's see how he organizes his ideas in the email.
Step 3 Practice 巩固练习（15~20 min）
3.1 3b Put the things in order 逻辑排序（5~6 min）
【教师活动】布置3b排序任务：T: Put the things in order to see how Zhang Peng organizes his ideas in writing. 教师引导学生理解6个句子的含义，讨论邮件内容的组织逻辑。教师提示：思考写邮件时应该先说什么、后说什么，为什么这么安排。
【学生活动】Ss: 阅读6个句子，理解每个句子的含义，根据邮件逻辑进行排序。学生活动示例：5 ask John to help decorate the room（开篇请求）→ 4 describe how the room looks now（描述现状）→ 2 tell John about the plan for the walls（具体计划）→ 6 ask John to meet on Sunday at the paint shop（见面安排）→ 3 ask John to help choose some photos to hang on the walls（进一步请求）→ 1 ask John to bring the brushes（补充请求）。学生独立完成排序后与同桌核对。
【教师活动】教师核对答案并讲解邮件组织逻辑：T: The correct order is 5-4-2-6-3-1. 教师引导学生归纳邮件四步结构：①开篇说明核心请求→②描述现状及计划→③列出具体计划→④征求对方意见/推动互动沟通。教师提问：Why does Zhang Peng start with the main request Why does he describe the room first
【学生活动】Ss: 思考并回答教师提问，理解邮件组织逻辑。学生活动示例：S1: He starts with the main request so John knows what he wants right away. S2: He describes the room so John understands why they need to decorate it. 学生在笔记本上记录邮件四步结构。
邮件组织结构分析
【提示框】理解要点：求助邮件四步结构
求助邮件的标准组织结构：①开篇说明核心请求——让对方一开始就清楚主要目的（Can you help decorate my room ）；②描述现状及计划——方便对方理解请求的必要性（Right now, there's nothing on the walls...）；③列出具体计划——说清时间地点及具体行动，方便对方提前规划（After school on Friday...）；④征求对方意见/推动互动——用What do you think about... 等句型推动沟通。这种结构使邮件逻辑清晰、内容完整、语气礼貌。
【过渡语】【过渡语】We know how Zhang Peng organizes his ideas. Now let's look at the polite expressions he uses.
3.2 Underline polite expressions 礼貌用语分析（5~6 min）
【教师活动】引导学生划出邮件中表示礼貌的表达：T: Underline the expressions that show politeness. 教师引导学生关注三类礼貌表达：①用want to.../love...陈述需求；②用What do you think about... 询问对方意见；③用Can/Could you... 礼貌请求对方帮助。教师板书三类句型并举例说明。
【学生活动】Ss: 在课本3a邮件中划出礼貌表达，分类整理到笔记本上。学生活动示例：①陈述需求：I want to decorate my room with paper cuttings. / I love it because... ②询问意见：What do you think about putting up some paper cuttings on the walls ③礼貌请求：Can you help me / Could you bring a pair of yours 小组讨论：为什么用Could you... 比Can you... 更礼貌？
【教师活动】教师讲解礼貌用语的程度差异：T: Could you... is more polite than Can you... When we ask a friend for help, we should be polite. 教师带领学生朗读邮件中的礼貌表达，注意语气和语调。
【学生活动】Ss: 齐读邮件中的礼貌表达，模仿礼貌语气。学生活动示例：2名学生分角色朗读邮件，注意语音语调和停顿。其余学生评价：Did they sound polite Why or why not
邮件礼貌用语分析
【知识点】礼貌表达三类：①陈述需求用want to.../love...（I want to make some paper cuttings.）；②询问意见用What do you think about... （What do you think about putting up some paper cuttings ）；③礼貌请求用Can/Could you... （Could you bring a pair of yours ）。
【提示框】易错提示：What do you think about... 的用法
What do you think about... 意为'你觉得……怎么样？'，about是介词，后面接名词或动名词（doing）。正确：What do you think about putting up some paper cuttings （about后接putting）错误：What do you think about put up some paper cuttings （about后不能接动词原形）同义表达：How do you like... / What do you think of...
【过渡语】【过渡语】Now let's practice these polite expressions before we write our own email.
3.3 Let's practice 句子仿写（5~6 min）
【教师活动】引导学生进行汉译英句子仿写练习：T: Let's practice writing polite sentences. Look at the Chinese sentences and write them in English. 教师呈现两个仿写任务：①现在，墙上什么都没有。我想做些剪纸，贴在墙上。②周五放学，我们可以在学校门口见面，去买胶水和纸。我只有一把剪刀。你能带把你的吗？
【学生活动】Ss: 独立完成汉译英句子仿写，运用所学礼貌表达。学生活动示例：①Right now, there's nothing on the walls. I want to make some paper cuttings and put them up. What do you think about putting up some paper cuttings on the walls ②After school on Friday, we can meet at the school gate and go to buy glue and paper. I only have one pair of scissors. Could you bring a pair of yours 完成后与同桌核对答案，互相纠正语法错误。
【教师活动】教师核对答案并讲解重点句型：T: Right now, there's nothing on the walls. 注意there's nothing表示'什么都没有'。I want to make some paper cuttings and put them up. 注意put up表示'张贴'。Could you bring a pair of yours 注意a pair of scissors表示'一把剪刀'。
【学生活动】Ss: 在课本上补全仿写答案，用红笔标注重点短语（put up, a pair of, after school, at the school gate）。学生活动示例：小组内互相检查仿写句子，检查项目：语法正确、用词恰当、语气礼貌。
【过渡语】【过渡语】You can use these polite expressions well. Now it's time to write your own email.
Step 4 Production 写作输出（8~10 min）
4.1 3c Write an email 求助邮件写作（5~6 min）
【教师活动】布置3c写作任务：T: Write an email to ask a friend to help decorate your room. Below is a list of things you may need help with. 教师讲解写作框架，引导学生借鉴3a邮件的写作思路：①开头：说明核心请求（Can you help me decorate my room ）；②中间：描述现状（Right now, there's nothing on the walls...）+ 具体计划（After school on Friday...）；③结尾：征求意见（What do you think about... ）+ 礼貌收尾（Let me know if you can come. Best, [Your Name]）。教师提供可选帮助事项：buy some flowers, bring a pair of scissors, make paper cuttings, make a poster, buy glue, bring a painting, go shopping, bring a brush。
【学生活动】Ss: 根据3c提示和写作框架，独立完成求助邮件写作。学生活动示例：Hi [Friend's Name], I hope you're free this Friday evening! I want to decorate my room with paper cuttings. Can you help me Right now, there's nothing on the walls. It looks so empty! I think it is fun to make some paper cuttings and put them up. What do you think After school on Friday, we can meet at the school gate and go to the stationery store nearby to buy glue and colorful paper. Oh, and I only have one pair of scissors. Could you bring a pair of yours Let me know if you can come. Best, [Your Name]
3c求助邮件写作框架
【知识点】3c写作框架：开头说明核心请求（Can you help decorate my room ）+ 描述现状（Right now, there's nothing on the walls.）+ 列出具体计划（After school on Friday, we can meet...）+ 征求意见（What do you think about... ）+ 礼貌收尾（Let me know if you can come. Best, [Your Name]）。
【提示框】写作技巧：求助邮件写作三步法
第一步：仿写——参考3a邮件格式（称呼→正文→结尾→署名），模仿范文结构和语言风格。第二步：词汇激活——调用本单元装饰词汇（decorate, cover, poster, scissors, glue, paper-cut, paint, brush等）。第三步：礼貌用语运用——用Can/Could you... 提出请求，用What do you think about... 征求意见，用want to...陈述需求。注意邮件格式规范：有主题、称呼、正文、结尾敬语和署名。
4.2 Evaluation 写作评价与修改（3~4 min）
【教师活动】呈现评价表，引导学生从三个维度自查和互评：①逻辑清晰 内容完整：清晰表明请求朋友帮忙装饰房间的意图，描述房间现状，说明装饰计划，列出需要朋友帮忙的事项。②表达礼貌 语言正确：恰当运用礼貌表达，句子语法正确，表达通顺，无明显拼写错误。③格式规范 排版整洁：符合邮件格式要求，有邮件主题且简洁明了，有正确的称呼和署名，段落划分清晰。教师组织同伴互评：T: Exchange your writing with your partner. Read and give suggestions according to the evaluation table.
【学生活动】Ss: 根据评价表先自查自己的3c写作，再与同伴交换互评。学生活动示例：用三维度评价表给同伴打分并提出1-2条修改建议，如'你应该在开头说明核心请求''你的邮件缺少结尾敬语'。根据同伴建议修改初稿。2名学生上台分享自己的邮件。

【学生活动】Ss: 跟随教师齐读课堂总结内容，在课本p.19旁边标注6个核心词汇的音标和释义，并在笔记本上默写邮件四步结构（开篇请求→描述现状→具体计划→征求意见）。学生活动示例：口头复述邮件四步结构，并用自己的话解释每一步的作用。
【教师活动】教师强调本课难点：T: Remember, when you write an email, organize your ideas clearly. Start with the main request, then describe the situation, list your plans, and ask for your friend's ideas. Always use polite expressions like Could you... and What do you think about... 教师用提问方式检测学生掌握情况：What is the first step in writing a help-request email How do you ask for your friend's opinion politely
【学生活动】Ss: 回答教师提问，巩固本课难点。学生活动示例：S1: The first step is to state the main request. S2: I can ask 'What do you think about... ' 学生在笔记本上写下邮件四步结构和三类礼貌表达。
