Unit 13 课时2 Section A（3a-3b）（课件）英语人教版九年级全一册

该初中英语课件围绕“Save the Sharks!”主题，聚焦鲨鱼保护相关词汇（shark fin, endangered等）、文本逻辑（鱼翅贸易危害-生态影响-保护行动）及核心事实（每年约7000万条鲨鱼被捕捞等）。课堂导入先展示金丝猴等国内濒危动物，再过渡到鲨鱼，构建从已知濒危动物到鲨鱼保护的学习支架，衔接自然。 其亮点在于通过任务链（预测文本来源、匹配段落大意、填写保护行动图表等）培养语言能力，渗透环保意识（文化意识）。如While-reading提取关键数据，Post-reading用“问题-分析-解决”逻辑梳理，分层作业（基础句型仿写、短文写作、宣传卡制作）提升思维品质与学习能力。助力学生提升语言运用与社会责任感，教师教学环节清晰可操作。
