Unit 5 第3课时 Fuel up & Hit it big（讲解课件）-【优翼·学练优】2025-2026学年新教材三年级英语下册同步备课（外研版三起）

该小学英语课件围绕时间表达（am/pm）、字母Dd(/d/)与Tt(/t/)发音及时差概念展开，通过复习旧词（如clock、half past one）、歌曲引入（Aa与apple）搭建学习支架，以Toby Tiger和Danny Dog的跨城市通话情境衔接新旧知识，引导学生理解不同地区时间差异。 其亮点在于情境化与跨学科融合，通过“Listen and chant”音频活动、时差小知识拓展及发音规则分类（如Dd对应dinner、dog，Tt对应time、tiger），培养语言能力（对话表达）、文化意识（跨地域时间认知）和思维品质（规则分析）。学生能提升综合语言运用能力，教师可借助情境与活动优化教学效果。
