Unit 5 返回导航 * Unit 5 　Information Technology Section Ⅰ　Topic talk & Lesson 1 Unit 5 返回导航 * How to Survive a Sandstorm Sandstorms 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. Unit 5 返回导航 * 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 accompanied by high temperatures，and you can quickly become 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. Unit 5 返回导航 * Outrun 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 (比……跑得快) it.Some sandstorms can travel at more than 75 miles per hour，but they often travel much slower.Trying to outrun a storm，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. Unit 5 返回导航 * 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 Unit 5 返回导航 * (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.
