Unit 2 A green life Get ready & start up（课件） -2026-2027学年外研版（三起）英语五年级上册

该小学英语课件围绕“绿色生活”主题，核心知识点为环保“三个Rs原则”（Reduce/Reuse/Recycle）及相关词汇、祈使句语法。课堂导入通过“Look and find”识别旧物、“Think and answer”思考再利用、Radio歌曲激活兴趣，从物品认知到原则理解再到实际应用，搭建图片匹配、对话练习等学习支架。 其亮点在于融合语言能力与思维品质，通过“Read and match”匹配原则含义、小组用旧物制作鸟屋等任务，培养学生问题解决与创意表达。结合音频对话（如Amy保留旧裙子）和Show time展示，提升语言运用与环保意识，为教师提供结构化教学素材，助力高效课堂。
