Unit 4 Section B (4a～4c)课件2025-2026学年人教版英语八年级下册

该初中英语课件围绕“自然奇观”主题，聚焦自然奇观词汇、核心句型（最高级、大数字表达）及项目式任务（设计海报、报告）。课堂通过提问已知自然奇观导入，以分类词汇句型梳理、任务步骤分解（research→poster→report）和小组分工为支架，帮助学生整合知识并实践。 其亮点在于以项目式学习整合语言能力与实践，通过明确小组分工、多渠道搜集信息及多维度评估表（内容、设计、表达）提升学习能力，结合反思环节深化自然保护意识（文化意识）。如亚马逊雨林海报示例提供模板，助力学生清晰表达。学生能提升语言运用与合作能力，教师可借此高效组织教学。

They are a beautiful light display in the sky, caused by interactions between solar wind and Earth’s magnetosphere. We can usually see them in high-latitude regions, like near the North Pole. These lights have vibrant colors, such as bright green, soft pink, and deep purple. They dance across the dark night sky, looking like a magical, flowing curtain. It is truly a mesmerizing astronomical phenomenon that makes people feel the magic and power of nature.
