阅读理解【主题：人与自然　沙尘暴防护】
Dust storms (沙尘暴) appear when strong wind blows sand and dirt from a dry surface.Strong dust storms may cause people to die，so you should know how to protect yourself from dust storms when you meet them.
Be careful of dust storm warnings
Dust storms probably happen on hot summer days，and it's not safe for people to travel during this period.So you should listen to the local TV or radio before travelling，and consider changing or giving up your trip if dust storms are to come.
Be prepared
If you are in a place where storms often happen，carry a mask to keep dust and dirt away from your face，and a pair of glasses to protect your eyes.
Stay inside
Do not move around when a dust storm comes，as you will not be able to see hidden dangers.So if you are in a house，don't go out and just stay inside.
Protect yourself from flying objects
