UNIT 3 默写练习一 Topic Talk（课件PPT）-【步步高】2024-2025学年高二英语选择性必修第一册学习笔记（北师大版）

该高中英语课件聚焦环保主题核心词汇，涵盖conservation、plastic等单词及destroy→destruction等词形变化，辅以核心短语如do one’s part、switch to。课堂从单词默写导入，通过词形变化填空和短语练习，搭建从词汇记忆到语境应用的学习支架，衔接基础词汇与应用能力。 其亮点在于以环保主题为载体，通过词形变化填空（如用recyclable完成垃圾分类句子）和选词填空（如用cut down、stop...from...练习短语运用），融合语言能力和思维品质的培养。采用“默写-填空-应用”渐进式教学，帮助学生巩固词汇基础，提升语境运用能力，也为教师提供结构化教学素材，提高课堂效率。
