Unit 6 Earth first Starting out + Writing 课件-2024-2025学年高中英语外研版必修第二册

该高中英语课件围绕“地球环境保护”主题，聚焦环境问题、原因及解决方案，通过视频数字记录（如森林消失面积、物种灭绝数量等）和漫画分析导入，衔接作业中的环境问题回顾，构建“数据感知-问题归因-写作输出”的学习支架。 其亮点在于融合“数据驱动探究”与“情境化写作”，以视频警示数字（如每年130,000平方公里森林消失）和漫画分析（如水污染与不当废物处理的关联）为载体，提升语言能力（信息提取与书面表达），培养思维品质（分析推断）和文化意识（人类命运共同体）。学生通过联系自身的倡议活动写作深化环保认知，教师可借助结构化任务链高效落实教学目标。
