教学设计：Symbols of American Culture （Reading for Writing · 人教版高中英语必修第三册 Unit 3） 授课对象：高一下 / 高二上　　课型：以读促写课（Reading for Writing） 产出任务：Write a short passage about Symbols of China using the structure learned. 一、Teaching Objectives（四维核心素养） 维度 具体目标 1. Language Competence （语言能力） 掌握说明文"主题句+支撑细节"的语篇结构；积累描述文化符号的核心词汇（symbol, represent, break through, make up, national pastime 等）及功能性句型（One of the most famous symbols of... is...; This is because...; Not only... but also...）。 2. Cultural Awareness （文化意识） 理解美国文化符号（fast food, baseball, jazz）背后的社会价值观与历史渊源；增强对中国文化符号的认同感，能用英语讲好中国故事，实现跨文化对比与表达。 3. Thinking Quality （思维品质） 通过"文本解构→结构归纳→迁移创作"的阶梯，培养逻辑分析能力；通过自评互评培养批判性思维与审美判断能力。 4. Learning Ability （学习能力） 学会运用"以读促写"策略，借助 checklist 进行写作自评与同伴互评，形成可迁移的英语写作元认知策略。 二、Teaching Key & Difficult Points • Key Points: 理解并运用 "Topic Sentence + Supporting Details (reasons / examples / data)" 结构进行写作。 • Difficult Points: 将阅读中习得的语篇结构和语言表达迁移到"中国文化符号"的写作中，实现内容逻辑与语言形式的统一。 三、Teaching Procedures Step 1: Lead-in（45min课堂：3min | 15min试讲：2min） 【设计意图】 激活图式，创设情境，引出"文化符号"主题，为读写任务铺垫。 【课堂指令】 "Good morning, everyone. Before we open the textbook, please look at the screen. Here are three blurred images. Let's play a guessing game. Image 1: golden arches, red and yellow... Yes, McDonald's! Image 2: a bat and a ball... Exactly, baseball! Image 3: a trumpet, improvisation... Right, jazz! What do they share? — They are all symbols of American culture. Today, we're going to read a text about them, and more importantly, learn how to write about our own cultural symbols like a native writer." 【鼓励与互动】 • 预设学生回答后："Sharp eyes! You connected the visual clues instantly." • 若学生迟疑："Good guess, but think about food. Yes, fast food! Don't worry, we're about to find all the answers in the text." 【15min试讲呈现】 快速展示3张图片，1个学生互动，立即导入标题，板书课题。 Step 2: Pre-writing（45min课堂：12min | 15min试讲：6min） 本环节分三层，体现难度梯度：文本理解 → 结构分析 → 语言积累。 Layer 1: Text Comprehension — Skimming for the "What"（2min / 试讲1min） 【课堂指令】 "Now, please skim the text in 1 minute. Don't read word by word. Just answer: How many symbols are discussed in detail, and what are they? Raise your hand when you find them." 【鼓励纠错】 • 学生回答正确："Spot on! Three symbols: fast food, baseball, and jazz." • 学生漏答："You're on the right track. The writer mentions three main ones in the body paragraphs. Can you check paragraph 2, 3, and 4 again? Yes, fast food, baseball, and jazz. The Statue of Liberty appears only briefly at the end as an extra example." Layer 2: Structure Analysis — Scanning for the "How"（6min / 试讲3min） 【设计意图】 这是本课的核心支架。通过"解构"范文，让学生发现"好文章是怎么写出来的"。 【课堂指令】 "Let's dig deeper. I'll divide the class into three expert groups. Group A: Focus on fast food. Find the topic sentence and underline the supporting details. Group B: Baseball. Group C: Jazz. You have 3 minutes. Go!" （45min课堂：真实计时3分钟，教师巡视指导；15min试讲：模拟巡视，快速过渡） 【模拟汇报与纠错】 "Group A, what's your topic sentence?" — 学生读："Perhaps one of the most famous symbols of the US is fast food." — 教师："Excellent reading! But is this sentence just an opinion, or does it introduce the whole paragraph? Right, it controls the whole paragraph. We call it the Topic Sentence."（板书：Topic Sentence） "What details support it?" — 学生："Drive-throughs are popular." — 教师："Good, but can you be more specific? What data did the writer use? Yes, '20% of meals are eaten in the car' and '10% of income on fast food'. These numbers make the argument strong. We call them Supporting Details."（板书：Supporting Details → reasons / examples / data） "Look at the blackboard. All three paragraphs follow the same pattern: Topic Sentence + Supporting Details. This is the golden structure for our writing today. Please write this formula in your notebook." 【鼓励】 • "Brilliant observation! You've discovered the writer's secret recipe." • "That's a very analytical mind. You've moved from 'reading the lines' to 'reading between the lines'." Layer 3: Language Focus — Accumulating the "Words"（4min / 试讲2min） 【设计意图】 从结构过渡到语言，为写作搭建"词汇-句型"支架。 【课堂指令】 "To write like this, we need some useful expressions. Please find phrases that show 'importance' and 'reason'. For example, 'Perhaps one of the most famous symbols...' 'This is because...' 'For one thing... For another...' I'll give you 2 minutes to hunt for them." 【教师提炼板书】 Useful Expressions for Writing: • One of the most famous symbols of ... is ... • This is because / The reason why ... is that ... • For one thing ... For another ... Finally ... • Not only does it represent ..., but it also shows ... • No wonder ... is called ... 【纠错示范】 "I heard someone say 'The reason is because...' — Be careful! In formal writing, we say 'The reason is that...' or simply 'This is because...'. Good try, but precision matters in writing." 【15min试讲呈现】 快速展示分组指令→模拟汇报1个段落→板书结构公式→展示语言框架（PPT或板书），全程约6分钟。 Step 3: While-writing（45min课堂：18min | 15min试讲：4min） 本环节分三步：头脑风暴 → 独立写作 → 自查修改，体现"过程性写作"。 Phase 1: Brainstorming — From America to China（3min / 试讲1min） 【设计意图】 从输入到输出的关键桥梁，实现文化迁移。 【课堂指令】 "Now, let's shift our focus from America to China. In your notebook, brainstorm one symbol of China. It can be food, sports, music, architecture, or anything. Then answer three questions: What is it? What does it represent? Why do people love it? You have 2 minutes. Write key words only, not full sentences." 【鼓励】 "There are no wrong answers here. Be creative! Tea, kung fu, the Great Wall, paper-cutting, dumplings... all are welcome." 【模拟分享】 "Time's up. Let me hear one idea. Yes, tea! What does it represent? 'Harmony and hospitality.' Excellent cultural insight!" Phase 2: Outlining — Applying the "Golden Structure"（3min / 试讲1min） 【课堂指令】 "Before you write, plan your paragraph. Use this outline on the worksheet: • Topic Sentence: One of the most important symbols of China is ______. • Detail 1 (Reason/History): ______ • Detail 2 (Example/Data): ______ • Detail 3 (Cultural meaning): ______ Complete the outline in 2 minutes. A clear outline is half the battle." 【纠错引导】 "I see some of you wrote very long topic sentences. Remember, a topic sentence should be clear and concise. It tells the reader what this paragraph is about. Don't put all details in it." Phase 3: Drafting & Self-checking（12min / 试讲2min） 【课堂指令】 "Now, turn your outline into a paragraph of about 80-100 words. You have 10 minutes. Use at least TWO expressions from our 'Useful Expressions' box. After writing, use this Self-checklist to revise your own work." 【Self-checklist】（PPT展示或发学案） □ Did I start with a clear topic sentence? □ Did I include at least two supporting details (reasons/examples)? □ Did I use at least two useful expressions from today's lesson? □ Are there any grammar or spelling mistakes? □ Is my handwriting neat and clear? 【15min试讲呈现】 "Okay, class, you now have 10 minutes to write. (模拟巡视，走到'学生'中间) I see you're using 'Not only... but also...' — nice choice! Remember to check your subject-verb agreement. (走向另一边) Your outline is very clear; now expand that second detail with a specific example, like a festival or a historical story. (看表) Time's up! Please put down your pens." 【鼓励】 "Don't worry about perfection in the first draft. Writing is rewriting. We'll polish it together." Step 4: Post-writing（45min课堂：9min | 15min试讲：2min） 本环节体现"教学评一体化"，分展示与互评两步。 Phase 1: Sample Sharing（4min / 试讲1min） 【课堂指令】 "I'd like to invite two volunteers to share their work. Who's brave? Yes, please read your paragraph aloud." 【模拟学生作品与点评】 学生读："One of the most important symbols of China is tea. It has over 4,000 years of history. This is because tea is not just a drink, but also a symbol of harmony and respect. For one thing, Chinese people serve tea to guests to show hospitality. For another, the tea ceremony represents the balance between humans and nature. No wonder tea is called the 'elixir of Chinese culture'." 【教师评价（示范深度反馈）】 "Outstanding work! Let me highlight three strengths: 1. Structure: Your topic sentence is crystal clear, and the three details flow logically. 2. Language: You've skillfully used 'For one thing... For another...' and 'No wonder...' — exactly what we learned today. 3. Culture: You didn't just describe tea; you explained its spiritual meaning. That's deep thinking. One tiny suggestion: 'This is because tea is not just...' — can we make it smoother? How about 'This is because tea is more than just a drink; it is a symbol of...'? See how the semicolon adds rhythm? Try it." 【鼓励】 "Don't just applaud — learn from her structure! Notice how she moved from history → social custom → philosophy. That's the depth we're aiming for." Phase 2: Peer-checking（5min / 试讲1min） 【课堂指令】 "Now, exchange your paper with your partner. Use the Peer-checklist to evaluate each other's work. You have 4 minutes. Be critical but kind. Find one strength and one suggestion." 【Peer-checklist】 Partner's Name: ______ Strength: I like your ______ because ______. Suggestion: You might improve ______ by ______. Score: ☆☆☆☆☆ 【15min试讲呈现】 只展示1个深度点评（如上），快速提及"Now exchange and peer-check"，不真等。 Step 5: Summary & Homework（45min课堂：3min | 15min试讲：1min） 【课堂指令】 "Let's wrap up. Look at the board. What did we learn today? Yes: 1. Content: American cultural symbols and their meanings. 2. Structure: Topic Sentence + Supporting Details. 3. Strategy: Read like a writer, write like a reader. Homework: • Level A (Basic): Polish your paragraph about the Chinese symbol based on your partner's suggestion and submit the final draft tomorrow. • Level B (Advanced): Write a complete web page about Symbols of China with an introduction, three body paragraphs, and a conclusion. Use the structure we learned today. Remember: Good writing is not about being perfect; it's about being clear, logical, and sincere. Class dismissed!" 【板书】 Symbols of American Culture → Symbols of China Structure: Topic Sentence + Supporting Details (reasons / examples / data / quotes) Useful Expressions: • One of the most famous symbols of ... is ... • This is because / The reason why ... is that ... • For one thing ... For another ... Finally ... • Not only ... but also ... • No wonder ... is called ... Writing = Clear Thinking + Precise Language 学科网（北京）股份有限公司 $
