Unit6 Section B（2a-3c）教学设计 2025-2026学年人教版八年级英语下册

课题 Unit 6 Crossing Cultures Section B (2a-3c) 学段 初中 年级 八 课型 词汇＆写作课 课时 5 学科 English 单元 主题分析 本单元属于“人与社会”范畴，涉及“跨文化沟通与交流，语言与文化”子主题内容，以跨文化交际为核心主题，内容涵盖世界各地的习俗差异、文化符号解读及跨文化情境下的恰当行为。单元目标明确，不仅聚焦语言知识（如结果、条件、时间状语从句），更强调文化理解与交际能力的培养，引导学生从认知习俗上升到理解文化内涵，最终实现有效的跨文化沟通与共情。 文本解读 What:本课时是人教版新版八年级下册第六单元Crossing Cultures的第五课时，本课时围绕“跨文化礼仪”主题展开，设计了词汇、语法、阅读与写作等多维度的学习任务。学生需掌握形容词否定前缀的用法，辨析-ed与-ing结尾的形容词区别，并通过阅读一封关于访问中国家庭的求助邮件，学习电子邮件的结构，最终以回信形式提供礼仪建议，完成从语言知识到实际应用的综合训练。 Why:本课时旨在帮助学生在跨文化交际中建立语言与文化的双向理解。通过词汇与语法练习，学生能够准确描述行为是否恰当；通过邮件阅读与写作，学生不仅学习电子邮件格式，更深入理解文化差异对社交行为的影响，培养文化敏感性与实际沟通能力，避免因文化误解导致失礼。 How:课时采用“输入—内化—输出”的渐进式设计。首先通过词汇变形与句子填空夯实语言基础；随后借助真实情境的邮件阅读，引导学生分析邮件结构并讨论中国礼仪；最后通过模拟回信任务，促使学生综合运用所学，在真实语境中完成跨文化建议的输出，实现知识与技能的双重建构。 学情分析 1.已有知识经验 学生在以往学习中已接触过基础形容词及其在简单句中的使用，具备初步的电子邮件阅读和写作经验。部分学生可能通过影视或旅行对中国礼仪有片段化了解。 2.潜在学习难点 学生可能难以将抽象的文化礼仪知识（如送礼禁忌、餐桌规矩）转化为具体、得体的英语表达；在跨文化情境中容易以自身文化为中心进行判断。 3.教学支持建议 借助视频、图片等多元素材呈现中国礼仪场景，提供范例句式与语块（如“It’s polite to…”“You should avoid…”），搭建语言支架。 教学目标 语言 能力 1.Students will correctly form negative adjectives using the prefixes un-, im-, and in-. 2.Students will distinguish between and accurately use adjectives ending in -ed and -ing. 文化意识 1.Students will develop sensitivity to cultural norms and avoid behavior that might be considered improper or rude in a specific cultural context. 2.Students will demonstrate respect for cultural diversity by providing considerate and context-appropriate advice for a cross-cultural visit. 思维品质 1.Students will analyze and categorize adjectives based on their prefixes and suffixes. 2.Students will compare and contrast cultural practices, identifying potential sources of misunderstanding. 学习能力 1.Students will apply vocabulary and grammar rules to new communicative tasks (writing an email). 2.Students will employ learning strategies such as using context clues, visual organizers, and model texts to complete structured writing tasks independently. 教学 重难点 教学重点 Students will understand the structure of a formal/informal email. 教学难点 Students can write a reply offering advice using appropriate vocabulary and sentence patterns related to etiquette. 教学过程设计 教学环节 教师活动 学生活动 设计意图 Step 1 Lead-in Teacher shows pictures of two social situations:one showing a formal greeting ( bow) and one showing an informal greeting (saying "hi" and waving). Asks: "What's the difference? How would you describe these greetings?" Students observe the pictures and respond using adjectives(eg, formal, friendly, polite, casual). 通过图片和引导性问题激活学生关于礼仪与行为描述的已有词汇，自然引出本课主题，并为本课词汇的导入做铺垫。 Step 2 Vocabulary in use Work on 2a 1.Teacher presents the adjectives from activity 2a and elicits the negative forms for "safe" and "proper". 2.Teacher clarifies the rule: un- is most common; im- often goes before adjectives starting with m/p (eg,mature, polite); in- is another common prefix.Then guides students to complete 2a individually or in pairs. 3.Teacher invites several students to share answers. Work on 2b 1.Teacher introduces 2b and lets students complete the sentences individually. 2.Teacher invites several students to share their sentences,and lets their partners judge if the sentences are correct. Work on 2c 1.Teacher writes two sentences on the board: "The movie was exciting." and "I felt excited." Asks students to identify the subject and discuss the difference. 2.Teacher explains the core rule: -ing describes the thing/person causing the feeling; -ed describes how someone feels.Then, teacher asks students to complete activity 2c individually by circling the correct words. 3.Teacher has students compare answers in pairs, then conducts whole-class feedback. Work on 2d 1.Teacher asks students to read the passage quickly for the main idea (using chopsticks properly). Then, instructs them to complete the blanks with words from the box, paying attention to the correct form (adjective VS. adverb VS. noun). 2.Teacher invites one or two students to share their answers by reading the whole passage,then gives some feedback on the students’ answers and pronunciations. 3.Teacher asks students comprehension questions: "What is bad manners?" "Why is using chopsticks challenging?" Connects the content to cultural etiquette. 1.Students complete 2a, writing down negative forms. 2.Students share their answers. 3.Students complete 2b using the correct negative adjectives. 4.Students share their sentences with the class. 5.Students analyze the example sentences. 6.Students finish 2c by circling the correct words. 7.Students compare their answers in pairs. 8.Students skim the passage and complete 2d individually. 9.Students check answers with the class by reading the passage. 10.Students discuss the questions and share with the class. 教师首先通过示范和归纳帮助学生掌握形容词否定前缀的构词法，并在句子填空中巩固。 通过典型例句对比，清晰讲解-ed和-ing形容词的核心区别，并立即在情境对话中应用，加深理解。 本环节将语言知识置于有意义的语境中应用。完形填空不仅检验学生对词汇形态的掌握，更将主题从一般行为礼仪聚焦到具体的“跨文化餐桌礼仪”，为下一部分的邮件阅读和讨论做好内容与话题上的衔接。 Step 3 Pre-reading Teacher displays the subject line of 3a “Home visit—Help needed!” on the board and asks students: “If you received this email from a foreign friend visiting your family, what would you think they are worried about? Have you ever felt nervous visiting someone from a different culture?” Students discuss in pairs for 2 minutes, then share their ideas with the class. 通过展示邮件主题，快速激发学生兴趣，引导学生联想跨文化拜访中可能遇到的问题。讨论环节激活学生已有经验，为后续学习做好铺垫。 Step 4 While-reading Work on 3a Fast reading 1.Teacher shows Tina’s email on the screen and explains: “Emails have different parts, just like letters. Let’s label them.”Teacher guides students to read the email quickly and identify. 2.After reading, teacher leads students to compare answers in pairs and invites several students to share their answers. Careful reading 1.Teacher asks students to read Tina’s email carefully and poses questions: -Why is Tina nervous? -What does she want to know? -What does “false impression” mean? 2.Teacher leads students to discuss in small groups and then invites some students to check answers. 1.Students read the email and label the different parts. 2.Students compare answers in pairs and share with the class. 3.Students read the email and discuss the comprehension questions. 4.Students share their answers with class. 通过可视化分析邮件结构，帮助学生系统理解英文邮件的组成部分，为后续写作环节奠定基础。 细读邮件理解内容，锻炼阅读理解。小组讨论提高解决问题的效率，为后续写作与分享预留更多的时间。 Step 5 Post-reading Work on 3b 1.Teacher divides the class into four “Expert Groups” and assigns each group one of the four categories from 3b. Instructs: “Your group is now the expert on your topic. Brainstorm 3-5 pieces of clear, helpful advice for Tina.” 2.Teacher provides sentence starters for advice:"It's a good idea to...""You should avoid...""Remember to..." "In China, people usually..." 3.Teacher circulates to provide support, then invites several students to briefly share their advice. 1.Students work in assigned "Expert Groups" to brainstorm specific advice for their given category. 2.Students briefly share their advice. 通过分小组“专家式”头脑风暴，高效收集关于不同礼仪主题的具体建议，为写作提供丰富、有组织的内容。小组活动促进合作学习，降低个人构思的难度。 Step 6 Pre-writing 1.Teacher presents a simple outline on the board for the reply email: Greeting: Hi Tina, / Dear Tina, Opening: Acknowledge her email, express enthusiasm. Body: Address her questions one by one. Use paragraphs. Closing: Reassure her, wish her a good trip. Sign-off: Best regards, / Yours, / [Name] 2.Teacher asks: "Should we answer her questions in the order she asked them? Why or why not?" . Emphasizes using separate paragraphs for different topics. 3.Teacher introduces useful phrases: Opening: Thanks for your email. / I was happy to hear from you. / Don't worry too much! Giving Advice: I think it would be polite to... / My advice is to... / You might want to... Closing: I'm sure you'll have a wonderful time. / I hope this helps. / Feel free to ask more questions. 1.Students view and discuss the model outline. 2.Students create a quick outline for their own email, deciding what advice to include from the brainstorming session and how to organize it. 此环节是写作前的谋篇布局。通过提供清晰的回复邮件框架和功能性语言，引导学生从无序的“想法”转向有结构的“计划”，降低写作的认知负荷。学生个人制定大纲的过程，是将集体智慧内化并个性化组织的重要步骤，为独立写作搭建“脚手架”。 Step 7 While-writing Work on 3c 1.Teacher sets writing task: "Now, you are Yaming. It's time to write your email to Tina. Use your outline and the notes from your group." 2.Teacher plays soft and instrumental background music if appropriate. 3.Teacher circulates quietly and provides individual assistance. 4.Teacher reminds students this is a first draft. The goal is to get ideas down on paper; perfect grammar and spelling can be fixed later. 1.Students write the first draft of their email individually, based on their outline and brainstorming notes. 2.Students focus on developing clear paragraphs to address Tina's questions. 这是学生进行独立语言输出的核心阶段。安静且有支持的环境鼓励学生专注于表达内容。教师巡视提供“隐形支架”，针对个体需求给予帮助，而非打断全班的写作思路。强调“初稿”概念有助于减轻学生的心理压力，鼓励他们大胆写作。 Step 8 Post-writing 1.Teacher introduces peer review and explains its value: "Another pair of eyes can help us find mistakes and make our writing better." 2.Teacher provides a checklist: -Does the email have all the necessary parts? (Greeting, Body, Sign-off) -Are the ideas organized in clear paragraphs? -Does it answer Tina's questions about gifts, manners, and topics? -Is the tone friendly and helpful? 3.Teacher demonstrate with a volunteer or a sample sentence how to give constructive feedback. 1.Students read their partner's email carefully. 2.Students use the checklist to provide feedback. 同伴互评是过程性写作的关键。提供的检查清单将抽象的“修改”要求具体化，引导学生从内容、结构、语言等多个维度审视作文，培养他们的读者意识和批判性思维能力。同时，这个过程也是相互学习的机会。 Step 9 Summary Teacher summarizes: “Today we learned email parts, discussed cultural manners, and wrote an advice email. Please remember: good communication is clear and polite, whether in writing or in person.” Students think about one new thing they learned today about email writing or Chinese culture. 总结本课重点，强化学习成果，鼓励学生反思与内化。 Step 10 Homework Level A:Make a list of 5 "Dos" and 5 "Don'ts" for table manners in your own culture. Level B:Prepare a short dialogue (6-8 lines) between a host and an international guest. The guest should make one minor cultural mistake (eg, using chopsticks improperly), and the host should correct it politely. Level C:Tina worries about giving a "false impression." Do you think it's more important to strictly follow another culture's rules, or to be yourself and learn from mistakes? Write some sentences giving your opinion with a reason. 本作业设计遵循分层理念，旨在满足不同水平学生的需求。三层任务从巩固基础到拓展思维循序渐进，兼顾语言能力与跨文化交际意识的培养，鼓励学生在真实语境中运用目标语言。 板书设计 Unit 6 Crossing Cultures Section B (2a-3c) Good Manners in China Greetings Gifts Table Conversation | | Manners Topics (Use titles) (Fruit, Tea) (Chopsticks rules) (Family, Food) Sentence Frame for Advice: It’s proper/ polite to...

A good topic would be... 教学反思 1、 成功之处: 1.情景创设有效:以Tina的求助邮件作为主线贯穿课堂，成功创设了真实、有趣的跨文化交际情境，学生在解决Tina问题的过程中，自然地学习了目标语言和文化知识。 2.文化意识渗透自然:对“礼物”、“餐桌礼仪”等的讨论，不是简单的知识灌输，而是引导学生基于文本信息进行推测，培养了学生的文化敏感度和推断能力。 二、存在问题: 1.文化对比的深度不足:课堂活动多集中于介绍中国礼仪，但对于为什么会有这些礼仪以及与中国学生自身经历的连接挖掘不够，文化学习略显表面化。 2.高阶思维挑战有限:课堂主要围绕理解、记忆和应用，对于分析、评价和创造等高阶思维活动涉及较少。 三、改进措施: 1.深化文化探究:设计探究性问题如“为什么在中国用筷子指人不礼貌？”“如果Tina不小心犯了错，她应该如何得体地道歉？”鼓励学生思考文化背后的价值观。 2.融入高阶任务:在作业或课堂尾声增设一个“跨文化调解员”或“文化观察员”任务，让学生分析一个更复杂的文化误解案例，并提出解决方案，以提升分析、评价和创造能力。 学科网（北京）股份有限公司 $
