教学设计、课堂实录及教案：人教版初中英语九年级Unit8 It must belong to Carla Section B 2a-2e湖南省 - 湘潭
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。
学情分析：
九年级学生已经有了一定的英语基础，听说读写的能力都比较强。该班学生对Section A 部分的知识掌握情况较好，所以本节课将进一步巩固和拓展情态动词表推测的用法以及连词的正确应用。但是学生对于长难文章的阅读能力一般，本堂课就此情况对学生加以技巧的指导，有针对性地提高学生英语阅读水平。
教学设计思路：
本节课，一条主线，三个环节。本节课贯穿的主线是“未解之谜”。首先，通过观看视频，学生会了解这个介绍世界未解之谜的节目Discovery，接着设计了一个比赛活动，激起学生参与课堂活动的兴趣。本节课的环节主要分为三个环节，每一个环节在设置了相应的学习活动。Step one-Talk about the mysterious thing 趣味猜测，引人入胜。Step two- Walk into the mysterious place预测文章，泛读精读，环环相扣。Step three -- Know about the mysterious world 给学生充分展示自我的舞台，同时培养了学生的探索精神。
