Unit 6 Developing ideas 课件 2025-2026学年外研版英语八年级上册

该初中英语课件围绕“自然灾害应对与预警技术”主题，从2004年海啸事件切入，通过Tilly Smith救人事迹的听力材料（含填空、纠错练习）引入，逐步过渡到SAFETY NET应用、无人机等现代技术，以听力理解、对话练习为支架，帮助学生掌握相关英语表达及知识逻辑。 其亮点在于融合语言能力、文化意识与思维品质培养，如通过真实听力材料（Tilly案例、SAFETY NET对话）提升听说能力，结合中国灾害预警系统（短信、社区警报）增强家国情怀，通过无人机优缺点讨论（强风无法工作等）培养分析思维。采用任务型教学（小组介绍救生技术），学生能提升综合语言运用能力，教师可借助评价表高效评估教学效果。
