人教版九年级全册英语 Unit8 It must belong to carla. SectionB 2b 教案

Unit8 It must belong to Carla. Section B 2b
教材分析：
本单元的话题（topic）是神秘事件（Mysteries），要求学生能根据相关信息正确运用must, might, could, 和can’t进行推断。Section A 部分主要围绕“推测物品的归属展开”，并进一步引入“神秘事件”这一话题。Section B部分内容通过对疑似外星人事件的讨论逐步过渡到对巨石阵的介绍，语言输入量较大。这篇关于巨石阵的说明文涉及了英国文化以及一些含有连接词的复杂句子，需要引导学生在上下文语境中体会语言表达的确切含义。
