Unit1 SectionA open page 1a-1d课件2026-2027学年人教版英语九年级上册

该初中英语课件围绕“家乡变化”主题，涵盖相关词汇、句型及听说能力训练。课堂导入通过“Look and share”图片对比（过去光秃土地与现在绿色环境）引发兴趣，再以Li Rui家乡为例，通过Pre-listening（过去与现在特征梳理）、While-listening（听力对话与表格填写）、Post-listening（对话补全）构建学习支架，衔接从感知到应用的学习脉络。 其亮点在于融合语言能力与思维品质培养，通过音频听力（1b电话对话、1c家乡变化介绍）训练信息提取，用“过去vs现在”表格对比（交通、医疗等）强化语言表达，Further Thinking问题（变化原因、意义）提升分析能力。Show Time的自评互评表促进合作学习，语言点（used to be用法、take/spend辨析）结合例句与练习巩固基础。学生能提升综合语言运用与逻辑思维，教师可直接使用完整教学流程与评估工具，提高教学效率。

Unit One The Changing World Sec A Open page-1a-1d What brings about changes? Look and share 1.How are these two photos different? 2.How has this place changed over time? 3.Why do you think this place changed so much? The first photo shows a bare（光秃秃的）and open land with only one tree. The second photo shows the same place now, with green grass, many trees, and a clear river. The place used to be dry and empty. Now, it is full of life. The land has become greener, there are more plants, and the river flows through the area. I think people worked hard to protect the environment. They planted many trees, took care of the land, and saved water. These efforts helped the place become green and beautiful again. 中 国 的 变 化 Pre-listening 1a:The photos show changes in Li Rui's hometown over the years. What are they? How do they make you feel?
