教材分析
【What】本课时主题聚焦自然奇观(The Wonders of Nature),聚焦大堡礁(Great Barrier Reef)与青海湖(Qinghai Lake)两大世界级自然景观。3a 是一篇介绍大堡礁的广告类短文,描述其地理位置、规模、生态景观与游览体验,引导学生识别数字、形容词和副词。3b 以笔记形式呈现青海湖的核心信息(类型、位置、面积、特色、活动),要求学生将零散信息整合成完整句子。 3c 要求学生模仿大堡礁广告,为青海湖或其他自然奇观撰写有说服力的宣传文案,完成从输入到输出的语言实践。 【Why】本课时语篇旨在引导学生认识和欣赏地球自然之美,培养保护自然生态、热爱地球家园的意识;通过对比中外自然奇观(大堡礁 vs 青海湖),增强学生对中国本土自然景观的自豪感,拓展国际视野;让学生在语言学习中感受自然奇观的独特魅力,激发探索世界、亲近自然的兴趣。 【How】本课时主要语篇 3a为广告类说明文:开头用设问句吸引读者兴趣,引出大堡礁;主体部分依次介绍地理位置、规模数据、生态特征与游览活动; 结尾用情感化表达(the dream of a lifetime)强化吸引力,符合广告的说服功能。3b(信息笔记→完整句子):从关键词到完整句的过渡,训练学生信息整合与句式构建能力。3c(创意写作):模仿3a的广告结构,要求学生自主组织信息、运用描述性语言完成宣传文案,实现语言输出。大量使用描述性形容词(amazing, biggest, largest, clear, colourful, white)和副词(most, even),增强画面感与感染力;出现具体数字(345,000, 900, 4,340)体现准确性;使用设问句(Do you love… )吸引注意力;用条件状语从句(If you visit it, you will…)引导读者想象游览体验;最高级(the most amazing, the biggest, the largest)用于突出景观独特性。语篇介绍了自然景观的特征、规模与活动;广告文体旨在吸引游客,激发参观意愿;笔记转完整句训练学生信息梳理与表达能力。
