Teaching Interpretation





Teaching philosophy
1.培养英语学科核心素养：注重语言能力培养，通过阅读文本、完成填空、总结文章等活动，锻炼学生词汇运用、语法理解和书面表达能力。
2.以学生为中心的教学理念：充分考虑学生已有的知识和经验，以学生对鲨鱼的初步印象和感受为切入点，激发学生的学习兴趣和主动性。
3.情境教学与知识迁移：运用电影片段、图片等创设生动的教学情境，将抽象的知识具象化，帮助学生更好地理解和吸收。例如，通过《大白鲨》电影片段引入话题，让学生直观感受人们对鲨鱼的恐惧。引导学生将所学知识迁移到实际生活中，思考如何保护濒危鲨鱼，培养学生运用知识解决实际问题的能力，强化学生对人与自然和谐共生的认识，增强学生的社会责任感。
4. 跨学科融合与拓展：将英语学习与生物、环保等学科知识相融合，拓宽学生的知识面。在介绍鲨鱼濒危现状时，涉及生物多样性保护知识；探讨保护措施时，引导学生从环保角度思考。同时，推荐相关电影和纪录片，鼓励学生在课后进一步探索，培养学生的综合素养和终身学习意识。

SHARKS: DANGEROUS OR ENDANGERED
1. Analysis of the Teaching Materials
本文选自外研社新教材高中英语必修二Unt6 Earth first,课文围绕“鲨鱼是危险动物还是濒危动物”这一问题展开讨论。文章第一、二段围绕“鲨鱼是危险的动物”这一主题展开。文章开头是场景引入，通过对电影《大白鲨》开篇镜头的描述引出人们对鲨鱼的普遍认知。第二段则通过举例来进一步说明人们对鲨鱼的错误认知以及产生的影响。第三、四段围绕“鲨鱼是濒危动物”这二主题展开。第三段重点描述了人们割鳍弃鲨，给鲨鱼带来了深重的灾难。第四段描述了《大白鲨》电影原著作者Peter Benchley为扭转人们的观点而奔走呼告。第五段是对标题的解答，作为总结，告诉读者鲨鱼并非危险的动物，目前濒临灭绝，越来越多的人已加人了保护鲨鱼的行列。
本节课的授课对象是普通高中一年级学生。学生了解鲨鱼的基本信息，并认为鲨鱼是危险动物，但是对于鲨鱼被认知为危险动物的原因思考较少，对于鲨鱼是濒危野生动物的现状知之甚少。学生可以通过语篇分析总结出文本结构，并且可以运用已有的语言知识完成大部分课堂活动，但教师仍需要借助于问题引领，引导学生进行更高层次的思维。
