Unit 4 Section B(2a-4d)-【初中学霸创新题】2025-2026学年新教材八年级上册英语同步课件(人教版2024)

该初中英语课件聚焦新词汇（如happiness、climate）、词缀构词（-ance、-(t)ion等）、词义分类及动植物主题应用，通过Warming up活动（描述动植物特征、辨析不同类单词）搭建学习支架，衔接后续词义分类练习（如区分动词与名词）、词缀构词训练，形成从基础认知到综合应用的脉络。 其亮点在于融合语言能力、思维品质与学习能力培养，如2a环节通过分析词性（enjoy为动词不同于其他名词）、情感色彩（smart为褒义词不同于其他贬义词）提升思维逻辑性，小组海报项目（如“最可爱动物”熊猫海报）整合信息收集与合作表达强化学习能力。学生在实践中深化词汇运用与主题认知，教师可依托结构化活动提升教学效率。

学习本课时新单词和短语：happiness, disappoint, mushroom, ton, role, pea, climate, ocean, except, tiny, lively, play a role (in)。 能找出同组单词中不同类的一个，能掌握由后缀-ance, -(t)ion, -ness和-ity构成的名词，能正确运用本单元的重点词汇。 Learning Goals 1 2 思考并分享动植物对人类的重要性。 3 小组合作，制作一张关于动(植)物的海报。对本单元的学习情况进行自我反思。 4 1 How to describe a plant or an animal? 1. name 5. weight 3. height 4. size 2. habit 6. food 7. habitat 8. age 9. importance 10. … Warming up Which word is different from the others?
