Unit 4 The Earth Grammar Using there is are课件2025-2026学年沪教版七年级英语上册

该初中英语课件以“there is / are”语法点为核心，通过海洋污染场景（干净与污染海洋对比图片）导入，逐步讲解单数/不可数名词用there is、复数名词用there are的基础用法，延伸至一般疑问句、缩略形式，最终结合垃圾分类实践（描述不同垃圾桶中的垃圾），构建从情境感知到语法应用的学习支架。 其亮点在于将语法学习与环保主题深度融合，借助真实场景图片和垃圾分类任务，培养学生的语言能力（如用there is / are描述垃圾分布）和思维品质（分析污染原因），同时渗透环保意识（文化意识中的社会责任感）。通过判断练习、句子写作等分层活动，学生能在真实情境中掌握语法并提升语言应用能力，教师可直接利用情境素材和练习设计提高教学效率。
