英语人教版九年级全册Unit 8 Section B 2a-2d.doc

Unit8 It must belong to Carla. Section B 2a-2d Stonehenge-Can Anyone Explain Why It Is There? 教学设计 四中 刘超一、教材分析本单元主要讨论关于“mysteries”这一话题。Section A 主要围绕“推测物品的归属”展开，并进一步引入“mysteries”这一话题，集中呈现与学习表示推断的相关词汇。Section B通过对疑似外星人事件的讨论逐步过渡到巨石阵的介绍，是对Section A 所学知识的巩固、拓展与提升。本节课是阅读教学部分，阅读材料是关于巨石阵的说明文。阅读语篇涉及英国文化，还涉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。 学生在学习了Section A以及Section B阅读教学之前的内容后，对于本单元的话题已经有了一定程度的知识积累，因此学习本节课应该不是很难。二、学生分析九年级的学生虽然在英语语言方面已经有了一定的基础，但对于英国文化却知之甚少，很多同学对巨石阵都闻所未闻，所以需要教师补充文化方背景。巨石阵对学生来说既遥远又神秘，能勾起学生强烈的好奇心和探索欲，相信学生会有一番紧张而刺激的探索之旅。三、教学目标1. 知识目标（1）学习使用连词，并借助连词的意义理解文章。（2）进一步理解和掌握情态动词表示推测的用法。（3）了解巨石阵的奥秘。2. 能力目标 学生能够掌握一定的阅读技巧，提高阅读能力。3. 情感目标激发学生学习兴趣，同时拓展学生的知识面，使学生放眼看世界。四、教学重点1. 掌握情态动词表推测的用法。2. 介绍连词的用法，并借助连词理解文章。五、教学难点阅读短文，获得相关信息，提高学生们的综合阅读能力。六、教学过程Step1.
