九上 Unit 5 第5课时 Section B 3a～Project（分层讲练册）-【众相原创】2026-2027学年九年级全一册英语分层练同步课件（人教版·新教材 广西专版）

该初中英语课件围绕“科学技术与工程，人类发明与创新”主题，聚焦英语说明文写作，通过话题概述明确课标主题及描述发明、讨论影响、探寻故事三个角度，以典例探究（李明设计英语智能App）为实例，结合四步法写作（审题、篇章布局、教材句型运用、连句成篇）搭建学习支架，衔接实战演练（李华“伟大发明与发现”演讲），形成从基础到提升的写作训练脉络。 其亮点在于分层设计与中考同步，以四步法写作指导为核心，通过具体实例（如用被动语态介绍App功能、仿写教材句型阐述App优势）提升语言能力，通过分析文体、人称、时态及构建篇章结构培养思维品质。采用“典例探究+实战演练”模式，学生能系统掌握说明文写作方法，教师可利用分层练习实现精准教学，有效提升教学效率。
