【开学备课包】2026-2027学年 人教版九年级上册英语 Unit1 The Changing World SectionA 1a-2d 课件 + 配套教学设计

该初中英语课件聚焦“used to”结构及家乡、环境变化话题，通过“Changes Around Us”头脑风暴导入，从核心词汇（hometown等）、语法（used to肯定/否定/疑问）到听力训练（1b-2c）再到口语应用（小组讨论），搭建观察到表达的学习支架，衔接紧密。 其亮点在于融合语言能力与思维品质，听力策略指导（先预测抓关键词）提升理解能力，Past-Present对比表格、问题-行动-结果逻辑链（如2c三栏结构）培养分析思维，常见错误提醒（如“didn't use to”用法）助力学生自我纠错，教师可直接应用结构化资源实施互动教学，提升课堂效率。

人教版初中英语9年级上册 Unit 1 The Changing World — Section A 1a-2d教学设计 1.基础信息 项目 内容 年级册别 九年级上册 学科 英语 教材版本 人教版（2026秋） 授课类型 听说课 总共课时 6课时 第几课时 第1课时（Section A 1a-2d） 2.教学设计 （1）教材分析 本课时为Unit 1 The Changing World的听说起始课，主题围绕"身边的变化"展开。Section A 1a-2d通过Li Rui与George及其父亲的对话，引导学生关注家乡在交通、医疗、购物和环境等方面的变化，同时引入环境问题（沙尘暴、耕地短缺）及治理措施。核心语法为"used to"结构表达过去的状态与习惯，以及现在完成时描述变化结果。听力活动从电话对话（1b）到实地参观对话（1c）再到环境治理对话（2b-2c），层层递进，既训练听力理解，又为口语输出提供语言支架。 （2）学情分析 九年级学生已具备一定的英语听说基础，能够进行简单的日常对话和短文听力理解。但"used to"结构是新课重点，学生容易与一般过去时混淆；听力中捕捉关键信息填表的能力仍需训练。学生对家乡变化和环境保护话题有生活体验，容易产生共鸣，但用英语表达变化和原因有一定困难，需要教师搭建语言框架。 3.教学目标 （1） 语言能力 1. 能听懂关于家乡变化的对话，捕捉关键信息（交通时间、医疗、购物、环境等变化细节） 1. 能使用"used to + 动词原形"描述过去的状态和习惯，并与现在进行对比 1. 能运用"It takes/took... to..."结构表达交通方式与时间 1. 能就环境问题及解决方案进行简单讨论 （2） 文化意识 1. 了解中国乡村振兴和生态环境治理的成就，增强民族自豪感 1. 关注身边的变化，培养对家乡发展的关注和热爱 （3） 思维品质 1. 通过对比过去与现在，培养比较思维和因果推理能力 1. 通过讨论环境问题的成因和解决方案，培养批判性思维 （4） 学习能力 1. 掌握听力前预测、听力中抓关键信息、听力后归纳的听力策略 1. 能借助表格和思维导图整理信息，提高信息组织能力 4.教学重难点 （1） 教学重点 1. 核心词汇：hometown, rough, road, environment, sandstorm, farmland, bush, root, soil, improve, technology, lack 1. 核心句型：used to do sth.; It takes/took... to do sth.; have/has done（现在完成时表变化结果） 1. 听力策略：根据表格预测内容、捕捉关键词填空 （2） 教学难点 1.
