Sandstorms in Asia（外研版高中英语必修3第4模块） 姓名 彭静 单位 西乡二中 课型 阅读课 课时 第2课时 教学对象 高一（6）班 是否采用多媒体 是
一、教材分析 本模块主题是“Sandstorms in Asia”, 亚洲的沙尘暴。沙尘所挟带的污染物和有毒重金属，对环境和人体健康造成影响。沙尘暴转趋频繁，是全球自然灾害日增大趋势的一部分。根据估计，沙尘暴每年造成的综合经济损失可达65亿美元。 READING AND VOCABULARY合并为第二课时“阅读课”。课文“Sandstorms in Asia”属说明文体，介绍了沙尘暴的特点、世界沙尘暴重灾区和中国面临的沙尘暴和荒漠化问题。对于阅读课如何上,师生各有己见。但阅读的目的就是培养阅读策略，培养语感，特别是培养学生在阅读的过程中获取和处理信息的能力。在这个过程中教师起着鼓励，启发，引导，帮助，监控，参与，反馈与评价的作用 二、学情分析 我所带的学生英语基础较差，在阅读的基本能力方面学生的猜词义，推理判断能力较差。基于此在有限的课堂教学中，着重培养这方面能力和给予学生启发和思考是教师的第一要务。 本节课vocabulary为其内容之一，活动2，3均为词义理解的练习，但学生多习惯于学之前先学习词汇，这也是降低阅读难度的策略，但学生会减少在文中根据语境理解词义的机会，为此可以把这两个活动改为通过语境加深理解词义，掌握运用生词的活动。课前预习，课中检查核对，暴露学生理解中的问题，指导学生提高理解能力。 三、教学资源与策略 本节课除外研版必修3教材、录音资料外，还借鉴了《英语周报》、《优化探究》和《金色教案》中的一些好的方面，同时也通过互联网搜索了有关沙尘暴的一些资料和图片。 主要采用的教学策略有: 任务型阅读教学法和交际式教学法。

教学反思本节课设计的是外研社必修三第四模块Sandstorms in Asia,题型为Reading and Vocabulary.本模块主要介绍了亚洲（主要是中国）沙尘暴的情况，并引入了与沙尘暴和环保有关的词汇。
要求学生了解沙尘暴方面的知识并掌握相关词汇，培养学生用英语谈论沙尘暴及环保的语言能力。
一．准确定位教学目标，凸显阅读综合视野一堂课不可能面面俱到，也不能面面俱到。
对于英语阅读课，不同的解读视角，不同的设计目的，会产生不同侧重的阅读课堂。
但是，内容、语言和思维是不可分割的三位一体，三者不能分开独立处理，而是应该综合设计，并有所侧重。
基于本语篇的行文脉络和主要内容，制定了侧重内容层面的教学目标。
经过多次改版，对文本有了更进一步的了解，最终决定以disaster为主线，通过对文本的学习，运用思维导图，帮助学生归纳总结并描述沙尘暴的定义、地点、起因、影响、建议、措施。
同时，经过种种的尝试与思考，深刻地体会到是否能从学生出发，明确教学目标，仔细研究教学内容，准确定位语言输出点决定着一节课的成功与否。
因而，在处理一篇阅读文章的时候，不能单纯地以教师自己对文章的认知来设计教学步骤，不能以教学步骤来解析文本，而是应该站在学生的角度，根据学习目标，合理解析文本进而确立教学环节。
二．熟悉教学步骤，关注学生表现英语学科核心素养中的思维品质的培养，指的是思考辨析能力的培养，包括分析、推断、判断、理性表达、用英语进行多元思维等活动。
想要达到这一培养目标，我们就必须坚持引导学生学会思考，不断地给他们提供思考的机会，如果教师对教学目标，教学步骤不够熟悉，在课堂教学过程中会更加关注自己教学步骤，而忽略了学习的主体--学生。
文本的有些意义隐藏在字里行间，需要教师设计铺垫性任务，使学生通过比较、提炼、概括等活动，逐步体验并推断文本的隐含意义，从而使学生加深课文理解，积累阅读体验，使阅读成为主动的、语言与思维相互作用的、创造性的学习和运用语言的过程。

2．教材原句：The storms sometimes continue all day and traffic moves very slowly because the thick dust makes it difficult to see.
这种沙尘暴有时持续一整天，车辆开得很慢，因为浓浓的尘埃降低了能见度。 佳句诵读：The government is making efforts to make it possible for every child to receive education. 政府正努力使每个孩子都能接受教育。
