学习目标
通过本节课学习,学生能够:
1. 学生能够理解情态动词must/could/might/can't表推测的基本用法,通过分析对话中的物品特征、人物习惯等线索,识别不同情态动词所表达的确定性程度差异(如must表示高确定性,might/could表示可能性,can't表示否定推测)。(学习理解)
2. 学生能够在"失物招领""现象推测"等真实情境中,运用目标情态动词进行多轮对话,结合具体依据(如"She loves volleyball")合理表达推测,并初步学会根据交际需求调整语气强弱(如从"It must be..."到"It might be...")。(应用实践)
学生能够将所学推测性表达迁移至4C部分新场景,通过小组合作提出有依据的假设,并设计简单的调查报告,用英语呈现推测过程与结论,培养逻辑思维与批判性表达能力。(迁移创新)
