Module 4Sandstorms in Asia【美文阅读】How to Survive a SandstormSandstorms are among nature's most violent and unpredictable phenomena(现象)．High winds lift sand into the air，reducing visibility(能见度) to almost nothing in a few seconds.Nearly all dust storms are capable of causing property damage，injuries，and deaths.No matter where you live，it's a good idea to know what to do if you see a wall of sand racing toward you.Here are some tips for you.Be prepared.If you are in a stormy area，carry a mask designed to remove small sand，and bring airtight goggles(密封护目镜) to protect your eyes.It's also wise to carry a supply of water in case you are tracked in a storm.Dust storms are usually acpanied by high temperatures，and you can quickly bee dehydrated (脱水的)in the dry heat and high winds.Wear or carry clothing that covers your body to protect yourself from the sandblasting，and to keep warm.Outrun(比……跑得快) the storm.If you see a sandstorm from a distance，and you are in a vehicle or have access to one，you may be able to outrun it.Some sandstorms can travel at more than 75 miles per hour，but they often travel much slower.Trying to outrun astorm，however，is not advisable if you have to put yourself at risk by traveling at high speed.If the storm is catching up with you，it's best to stop and prepare for it.Take cover and stay still.Do not attempt to move about in a storm，as you will not be able to see potential danger in your path.If you're in a house，stay inside.If you can quickly reach such a place before a sandstorm reaches you，get there as quickly as possible.Close all windows and doors，and wait out the storm.If you're in a vehicle，roll up the windows and turn off the vents that bring outside air in.If you are outside，seek out a large rock to protect yourself at least partially.Protect yourself from flying objects.Cover as much of your body as possible to protect yourself from flying sand.In addition，while the sand can hurt，a sandstorm's high winds can also carry heavier(and hence more dangerous) objects.If you find yourself no place to stay，try to stay low to the ground and protect your head with your arms, or a backpack.【诱思导学】Sandstorms have been a major disaster for many Asian countries for centuries.What should we do to reduce or stop sandstorms?【答案】Students' own answer.Period ⅠPreviewing●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，对下一堂课对课文的全面理解起到一个铺垫作用。

Module 4 Sandstorms in Asia教学设计说明话题介绍本模块主题是”Sandstorms in Asia”, 亚洲的沙尘暴。

亚洲沙尘暴的发生频率，50年来已增加5倍，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。

中国的沙尘暴发生频率在过去50年里增长5倍，上世纪50年代是5次、60年代是8次、70年代是14次、80年代是15次、90年代则达到24次。

沙尘暴引起高度关切的一个重要原因，是它在经过中国北部工业区上空时，会吸入铅等有毒重金属微粒。

这种有毒沙尘会引发呼吸系统疾病，对老人和儿童甚至有致命危险。

根据估计，沙尘暴每年造成的综合经济损失可达65亿美元。
