Unit 5 The power of plants Starting out & Understanding ideas (Reading)课件2026-2027学年外研版英语七年级上册

该初中英语课件围绕“植物的力量”主题，核心讲解光合作用过程、“plant”的双关语义及植物多维度价值。课堂导入通过“人类与植物能力对比”“图片匹配活动”等热身环节，引导学生从已知植物现象过渡到抽象原理，搭建具象到抽象的学习支架。 其亮点在于运用拟人化（“工厂车间”“工人”比喻叶绿体）和双关语，结合“选择标题阐述理由”“小组对比标题”等活动，培养语言能力与思维品质。如阅读环节将光合作用具象为“工人生产糖和氧气”，“Think and share”引导思考生态价值，渗透文化意识。学生提升语言运用与逻辑思维，教师获清晰流程与多样活动设计。
