Sandstorms in Asia(外研版高中英语必修3第4模块)
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）班是否采用是多媒体一、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。
