Unit1 The Changing World Section B (1a-1e) 教学设计 【教学目标】 语言能力。掌握 railway, transport, link, rough, passenger, convenient, benefit, deal 等核心词汇及 cut the travel time, take place, benefit from 等短语；能运用现在完成时描述变化带来的影响；能读懂关于蒙内铁路的说明文，提取数字、事实与人物观点等关键信息。 文化意识。了解中国援建肯尼亚蒙内铁路的背景与意义，认识国际合作对发展中国家民生改善的作用，理解"一带一路"框架下中非合作的共赢内涵。 思维品质。能通过对比新旧铁路的差异，分析交通基础设施变化对经济、社会和个人生活的多重影响；能评价标题 "On the Fast Track" 的字面义与比喻义。 学习能力。运用略读抓段落主旨、寻读定位数字信息的阅读策略；能在小组讨论中用英语表达对"变化与发展"的看法。 【教学重难点】 重点 梳理蒙内铁路新旧对比的关键信息（建造时间、里程、耗时、使用人数）；掌握核心词汇与现在完成时在描述变化中的运用。 难点 理解标题 "On the Fast Track" 的双重含义；从政府工作人员、商人等不同视角分析铁路带来的综合效益。 【教学过程】 Step 1 Lead-in（5分钟） 教师活动。展示中国高铁图片与肯尼亚地图，提问： How long does it take to travel from Suzhou to Shanghai by high-speed train? What do you know about Kenya? Where are Mombasa and Nairobi? Have you ever heard of a railway built by China in another country? 学生活动。自由发言，激活背景知识。教师顺势引出："Today we'll read about a railway that changed Kenya — the Mombasa-Nairobi Railway, built with China's help." 词汇铺垫。板书并领读核心词：railway, port, capital, transport link, rough, passenger, benefit。用简笔图示或英文释义快速突破：port = a city with a harbor for ships; capital = the most important city of a country; rough = not smooth, difficult to travel on。 Step 2 Pre-reading — Prediction（3分钟） 教师活动。呈现课文标题 "On the Fast Track" 和蒙内铁路图片，引导学生预测： · What does "fast track" literally mean? What might it refer to in this text? · Look at the title and the picture. What changes do you think the text will talk about? 学生活动。同桌讨论，写下2—3个预测内容。教师不急于公布答案，留待阅读验证。 Step 3 While-reading（20分钟） Activity 1 Skimming — Match main ideas（1a） 学生快速通读全文，将各段与段落大意匹配。教师提醒：关注每段首句和转折词（however, before then, now）。 Paragraph Main idea Para 1 The old transport situation before 2017 Para 2 The new railway and its basic data Para 3 Local people's benefits from the railway Para 4 The meaning of international cooperation Activity 2 Scanning — Find the numbers（1b） 学生寻读课文，圈出所有数字并完成表格。教师巡视，指导学生定位关键句。 Items Old New Year opened / built 1901 2017 Length — 480 kilometres Travel time (Mombasa → Nairobi) 10 hours 5—6 hours Annual passengers — over 2 million 核对答案后追问。"Which sentence tells us the old railway was built in 1901? Which word shows the contrast between old and new?" 引导学生关注 "Before then" "However" 等语篇标志词。 Activity 3 Detailed reading — People's views（1c） 学生精读第三段，找出文中提到的人物及其观点，完成下列信息梳理。 · A government worker: "I'm very happy with the new railway built by our Chinese friends. Many changes have taken place in the town, and the people who live here have become rich." · A businessman: （学生根据课文补充）The railway helps him transport goods faster and save money; it's safer and more convenient to travel; he can make business deals more easily. 师生互动。教师提问："Why does the government worker mention 'Chinese friends'? What does the businessman's story tell us about the railway's influence?" 引导学生从民生改善和经济发展两个角度归纳。 Activity 4 Language focus（1d） 教师从课文中选取典型句子，引导学生观察并归纳语言点。 句1。The new railway, built with China's help, has already cut the travel time to about five to six hours. → 现在完成时（has cut）强调过去动作对现在的影响；"built with China's help" 是过去分词短语作后置定语，修饰 railway。 句2。Many changes have taken place in the town over the last few years. → take place 表示"发生"，无被动语态；over the last few years 是现在完成时的典型时间状语。 句3。Local Kenyans have benefited a lot from the new railway. → benefit from 表示"从……中受益"，benefit 可作动词也可作名词（如：the benefits of the railway）。 Step 4 Post-reading — Discussion & Output（12分钟） Activity 5 Title appreciation（1e） 教师引导学生回到标题，深入理解： · What does "On the Fast Track" mean literally? (on a fast railway track) · What does it mean figuratively? (Kenya is developing rapidly; the country is on the fast track to progress) · Why is this title a good choice for the text? Activity 6 Group discussion 四人小组讨论以下问题，每组推选代表汇报： · What changes has the Mombasa-Nairobi Railway brought to Kenya? List at least three aspects. · Can you think of a similar project in China or in another country that has changed people's lives? · Do you think international cooperation is important for developing countries? Why or why not? 语言支架。教师提供常用表达，降低输出难度： · The railway has made it easier to... · Thanks to the project, people can... · From my perspective, international cooperation matters because... · A similar example is... 学生汇报。每组用1—2分钟分享讨论结果，教师点评并纠正典型语法错误。 Step 5 Summary & Homework（5分钟） 课堂小结。师生共同回顾：课文以蒙内铁路为例，通过新旧对比展现了交通基础设施变化给肯尼亚带来的经济发展和民生改善，也体现了中非合作的共赢意义。阅读策略上，我们练习了略读抓主旨和寻读定位数字。 作业布置。 · 基础。熟读课文，抄写并默写本课核心词汇与短语（railway, transport, link, rough, passenger, convenient, benefit, deal; cut the travel time, take place, benefit from）。 · 提升。用5—6句话复述蒙内铁路的故事，必须包含至少3个数字信息和现在完成时的句子。 · 拓展。采访家中长辈，了解家乡近十年的一项交通变化（如新建公路、大桥、地铁），用英语记录关键信息，下节课分享。 【板书设计】 On the Fast Track — Unit 1 Section B (1a-1e) Before 2017 (Old): rough roads + old railway (1901) → 10 hours After 2017 (New): 480-km railway (China's help) → 5-6 hours → 2M+ passengers/year Benefits: government worker → changes, richer; businessman → faster, safer, business deals Key structures: have/has + done; take place; benefit from; cut the time Title: literal = fast railway; figurative = rapid development 【教学反思】 本课为阅读课，以"新旧对比"为主线贯穿始终。数字信息表格能有效训练学生寻读策略，人物观点梳理帮助学生从不同视角理解文本影响。教学中需注意：学生对肯尼亚地理背景较为陌生，导入环节的地图和图片铺垫要充分；现在完成时是本单元核心语法，在语言聚焦环节应结合课文例句精讲，避免脱离语境孤立讲解。小组讨论环节的语言支架对基础薄弱学生尤为重要，可根据学情适当增加范例。整体时间分配上，精读与讨论环节容易超时，需注意把控节奏。 学科网（北京）股份有限公司 $
