任务型阅读,
Dust storms are here again.The people of Beijing are wearing masks (面罩) to protect their mouths and noses.The dust storms are a problem for the people of Beijing.For several years,the storms have made being outdoors dangerous.
Other areas in northern China face even bigger problems with sandstorms.
The sand and dust are a problem whenever the wind comes from the north.When the wind is strong,it carries dust and sand from the desert to north-west China.Often the sandstorms are so bad that drivers have to slow down and use their headlamps to help them see what’s in front of them.
The Central Meteorological Station (中央气象台) says that sandstorms are a problem in summer because the land is drier.This means that the earth does not stick to the ground and the wind carries more sand and dust.When there is more rain,this does not happen,but this area is one of the driest places in the country.Dust storms also affect (影响) other areas like central and northern parts of China.Gansu and Shanxi provinces are also affected.
Sandstorms are a difficult problem because of people’s carelessness with the trees and grasslands.People are cutting down too many trees and raising too many sheep or cows on grasslands.So many grasslands and farmland become desert or sand.One way to solve (解决) the problem is to plant trees to hold earth to the ground.This will also bring more rain because plants help make the world’s rain.So,solving the problem needs a long-term plan.Today,the people of northern China have to live with dust storms and protect themselves from the effects ( 结果 ) of this unpleasant natural disaster.
