Unit 3 The world of Science Understanding ideas 课件-2025-2026学年高中英语外研版（2019）必修第三册

该高中英语课件围绕“科学世界”主题，聚焦科技发明访谈文本，通过古今生活物品对比（古代纸笔、蜡烛 vs 现代电灯泡、电脑）搭建导入支架，引导学生用对比句型梳理生活变化，衔接后续访谈理解与发明主题探究。 其亮点在于以访谈为载体，通过预测问题、问题链分析（如Q5探讨发明灵感）及Think share活动，融合语言能力（访谈理解与表达）、文化意识（中国新四大发明等古今对比）和思维品质（分析发明动因），采用语境化词汇语法教学（如将来进行时、定语从句），助学生提升语言运用与探究能力，教师可高效开展主题式教学。
