Unit 3 New words & expressions 课件 2025-2026学年沪教版（2024）八年级英语上册

该初中英语课件聚焦词汇分类与运用，涵盖名词、动词、形容词、副词等词性及词形变化、固定搭配，通过系统分类导入，结合词形变化（如pay加-ment成payment）和搭配（如connect to）搭建学习支架，衔接重点词汇辨析（如interview的拓展、electronic的区分），形成“分类-解析-复习-练习”的完整学习脉络。 其亮点在于以分类构词与语境应用为核心，通过词形变化规律（如treat→treatment）培养学习能力，表格对比（如electronic/electrical/electric区分）发展思维品质，语境练习（如“Mobile payment makes shopping easier”）提升语言能力。学生能系统掌握词汇并灵活运用，教师可借助清晰结构高效开展词汇教学。
