Unit 4 Section B (Vocabulary in Use & 3a-3c）-【木牍中考】2026-2027学年八年级上册英语同步教学优质课件（人教版·新教材）

该初中英语课件聚焦八年级上册Unit 4“Amazing Plants and Animals”，核心涵盖名词后缀构词法（-ance, -(t)ion等）和动物主题写作。课堂以“找不同词”活动（如区分habit与height等）导入，通过语义、词性辨析激活旧知，搭建从词汇辨到构词规则的学习支架，再经填空练习巩固，最终过渡到蓝鲸文本阅读与改写，形成词汇-阅读-写作的连贯脉络。 其亮点在于融合语言能力与思维品质培养，如“找不同词”活动引导学生分析词性、语义范畴提升思维层次，名词后缀教学结合实例（happy→happiness）强化语言运用能力。写作环节通过蓝鲸文本结构分析（栖息地、食物等）到第一人称改写的支架设计，辅以“神奇大自然”“蓝鲸”视频增强情境感，既助学生提升词汇与写作技能，又为教师提供结构化、情境化的教学流程，提升教学效率。
