Unit 5 A fine balance Starting out课件 2026-2027学年外研版九年级英语上册

该初中英语课件围绕“人与自然的平衡”主题，核心涵盖自然环境词汇（wetland、rainforest等）、人与自然关系理解及定语从句that/which的初步运用。课堂导入通过图片观察、自然事物头脑风暴激活已知，再经图片匹配识别环境特征，讨论人类正负影响，最后在语境中渗透语法，构建从感知到应用的学习支架。 其亮点在于融合语言能力与思维品质培养，通过分层口语任务（基础描述/定语从句运用/影响分析）和60词短文写作提升语言表达，小组讨论“保护自然的原因”引导学生分析生命、家园等维度，培养批判性思维。采用情境化语法教学（如用“河流是提供水源的地方”等实例），迷你项目“自然保护计划”和分层作业（基础背诵/提升写作/拓展观察）促进学习能力。学生能在真实语境中运用语言，教师可通过结构化活动高效落实单元目标。
