Unit 5 Amazing nature Developing ideas 读写课课件 2025-2026学年外研版英语七年级下册

该初中英语课件围绕“Amazing nature”主题，聚焦死海、马达加斯加雨林、美国冰川等自然奇观的科普阅读，旨在帮助学生提取信息并掌握“dry up”“climate change”等自然环境相关词汇短语。课堂通过“Natural wonders”预测活动导入，结合单词拓展、短语及句型表作为学习支架，衔接前后知识，构建语言基础。 其亮点在于融合主题式写作指导与任务型练习，如“三段法”写作框架（自然之美—人类破坏—保护行动）和表格填空、仿写段落任务，既提升语言能力（词汇运用、信息提取），又培养思维品质（分析问题、解决问题）。学生能在实践中增强读写能力与环保意识，教师则可借助结构化资源高效开展教学。
