Unit 5 Into the wild Understanding Ideas课件 2026-2027学年高中英语外研版必修第一册

该高中英语课件围绕“动物迁徙”核心主题，以帝王蝶迁徙为载体，通过热身活动（图片认知动物迁徙行为、解释迁徙定义）、读前任务（圈出迁徙动物、预测文章内容）搭建学习支架，帮助学生从直观感知逐步过渡到文本理解。 其亮点在于融合语言能力、思维品质与学习能力培养，读中通过因果流程图分析人类活动对帝王蝶的影响（如森林砍伐导致栖息地破坏），读后借助思维导图和填空复述梳理迁徙信息，作业设计海报与写作任务。学生能提升逻辑分析与语言表达能力，教师可通过结构化活动高效落实核心素养。
