Unit 1 People of Achievement Learning About Language 五步教学法之非限制性定语从句 课件-2026-2027学年英语新人教版选择性必修第一册

该高中英语课件聚焦非限制性定语从句，通过翻译对比带逗号与不带逗号的句子导入，先复习定语从句定义、三要素及关系词，再以“我们一样吗？我们不一样~”引导探究限制性与非限制性的区别，搭建从旧知到新知的学习支架。 其亮点在于采用对比分析法（表格对比形式、翻译、功能等差异），结合丰富实例（如Peter回中国的非限定从例句、as引导的“as we all know”等固定句型），注重思维品质（分析比较）和语言能力（理解表达）的培养。总结系统梳理关系词及as与which区别，作业联系生活实际，帮助学生提升语言运用能力，教师可直接用于课堂，提高教学效率。
