　　Recently, sand storms have swept across many cities and areas of North China. Last week I saw the worst sand storm in years. It came suddenly and went on for more than three hours.

The sand storm was really terrible. When it came, the sky turned yellow and all the lightning bolts turned blue.The strong wind followed.All people hurried home. How terrible it was!

What should we do to prevent it from happening? We should plant grass and trees as much as possible. And the government has begun to take measures to fight against the sand storms. Many Asian countries like China, Korea and Japan will work together to stop the sand storms spreading.
