【答案解析】[范文]

Sandstorm is a kind of disaster climate. When it occurs, the sky will probably turn yellow and dark, and the wind blows strongly with dust and sand covering all around. To protect individuals from dust and sand attacking, people have to wear a dust-musk or a veil out. The low air visibility may affect the traffic safety, the wind and sand will pollute the city. What"s worse, the terrible air quality must lead to some respiratory illness.
Everyone and everything is under the influence of the sandstorm, which makes human being"s life inconvenient and unhealthy. In my opinion, there are two reasons causing the sandstorm. They are as follows: on one hand, over-herding destroys the plant, which is the main reason of vegetation. On the other hand, numerous trees have been cut down, the land desertification is deteriorating.
Sandstorm is a kind of nature"s revenge on what we have done to her. Before the seriousness of this nature disaster, effective measures should be taken before things get worse. All these measures should be cooperated by government and individuals. We should plant more trees and more grass to protect vegetation and to stop wind and sand blowing to the city directly. And the ways of breeding cattle need to be changed.
In conclusion, sandstorm poses a great threat to our quality of life, even to our existence. Although it is a long and hard task to fight against the sandstorm, it is a battle we must win and this needs everyone to take responsibility.
