Unit 1 Nature in the balance Welcome to the unit & Reading 课件-2025-2026学年高中英语译林版（2020）必修第三册

该高中英语课件围绕“Nature in the balance”主题，聚焦亚马逊雨林生态平衡及人类活动影响，通过提问“Are these problems new?”、引用恩格斯名言建立历史与现实联系，以镜头术语（定格、广角全景等）、生态分层、食物链分析为支架，引导学生从观察到分析再到创作纪录片脚本。 其亮点在于采用任务驱动的沉浸式学习，如“ROLE SHIFT”让学生扮演导演排列镜头、设计结尾脚本，提升语言能力；通过数据解读（如“17%雨林消失”）和生态案例分析，培养思维品质中的推断与评价能力；强调“人类命运共同体”，联系亚马逊与西双版纳生态保护，增强文化意识。学生能提升综合语言运用和批判性思维，教师可借助结构化活动设计提高教学效率。
