Unit 5 课时4 Section B 1a-1f（教学课件）英语新教材人教版九年级上册

该初中英语课件围绕“造纸术的起源与影响”展开，通过“物品材料识别”导入连接生活，Pre-reading词汇学习与标题预测搭建阅读支架，While-reading以略读匹配、代词指代分析、信息对比表格及步骤排序深化理解，Post-reading拓展至其他古代发明讨论，形成“导入-铺垫-深入-拓展”的知识脉络。 其亮点在于融合语言能力（代词指代训练、步骤英文复述）、文化意识（中国古代发明探讨增强家国情怀）与思维品质（对比分析材料变化、归纳发明品质），采用任务型教学（表格填写、步骤排序）和分层作业（基础背诵、拓展写作、实践短文），小结系统梳理词汇短语。学生能提升语言运用与文化自信，教师可获得结构化教学流程与多样化活动设计支持。
