Unit 4 Changing and Growing Grammar in Use课件2026-2027学年仁爱科普版英语八年级上册

该初中英语课件围绕Unit 4 "Changing and Growing"，聚焦-ful/-less构词法与过去进行时核心知识点。课堂通过图片例句（如医生无助与有帮助、支付符号有用与无用）导入构词法，对比后缀积极/否定含义建立词汇学习支架，再以小组对话示例过渡到过去进行时，结合时间标志词与结构讲解，形成从词汇到语法的递进脉络。 其亮点在于融合思维品质与语言能力培养，采用表格归纳构词后缀（如help→helpful/helpless）、任务型看图问答（描述昨天9点人们正在做的事）等学科特色方法。通过对比辨析构词法与两种过去时态，助力学生自主归纳规则，提升语境中语言运用能力，教师可借助系统练习与活动设计高效开展教学。
