Unit 3 On the move 词汇学习 课件-2025-2026学年高中英语译林版选修第一册

该高中英语课件聚焦选修第一册U3的18个核心词汇，通过词性标注、释义解析及派生词短语拓展构建学习支架，结合例句与专项练习（如“puzzle”的形式填空），帮助学生建立词汇间的逻辑联系。 其亮点在于以语言能力和思维品质培养为导向，通过派生词转换（如“revolution”拓展至revolutionary、revolutionize）、近义短语对比（如glance at与stare at辨析）等学科方法，强化词汇应用。既提升学生词汇辨析与运用能力，又为教师提供系统的词汇教学方案，提高课堂效率。
