1.教材分析:

本模块以Sandstorms为话题，通过本模块的几篇阅读材料使学生对

Sandstorms有所了解，并通过文章中提出的一些深刻的问题，比如，Thedesertis

only250kilometersawaytothewestofBeijing使学生更好地了解我们的地球和我

们的生活环境正遭受的破坏，并引发对“我们应该如何保护环境”的热烈讨论，通

过这些讨论会激发学生对环境保护的了解和实施的自觉性。通过讨论

Sandstorms,让学生表达对沙尘暴的看法，以及我们应采取何种措施来提高环境

质量。并能就此设计海报来呼吁人们保护环境。

1.1INTRODUCTION复习和学习有关自然灾害的词汇，呈现了一些自然灾

害的起因以及造成的危害，使学生对沙尘暴有初步了解。

课文。阅读文章后并完成练习，培养对词汇的应变力，理解力和分析问

题的能力。

1.3GRAMMAR1部分不定式的不同表达的区别，并会正确运用。

1.4LISTENINGANDVOCABULARY通过听的活动，了解和学习与环境有

关的词汇并学会表达，培养在听的过程中思维能力和获取信息的能力。

1.5GRAMMAR2了解but+infinitive的用法。

1.6PRONUNCIATIONANDFUNCTION学会expressstrongopinions的表达

法。

1.7SPEAKING1设置一个情景来表达在沙尘暴中的一次经历。

1.8SPEAKING2通过词汇练习来了解造成环境污染的一些东西，并就此提

出解决措施。

1.9WRITING先描述一些环境问题，然后再就此提出解决的措施，然后组

中加以运用。

1.11CULTURALCORNER了解一些欧洲国家在环保方面所采取的措

施。
