Mike and Dick work in the same office. They don’t like the cold weather. And one day they decided to take their holiday in Australia. Their plane arrived in Sydney at nine in the morning. They had a good rest in a hotel. The next morning they rented(租) a car in the city and began their travel. A few hours later the sun was shining in the sky and there were no shade trees(遮阴树) beside the road. It was so hot that they could hardly go on driving. They had to stop to look around. Mike found a river was about half a kilometer away from them. They were both very happy and drove the car quickly. Soon they got to the river. Before they jumped into the water, Dick saw a boy playing under a big tree. He asked,“Are there any sharks(鲨) in the river, boy?”“No, there aren’t,”answered the boy. So they began to swim in the river. After a while, Dick felt something hit against his leg. He told Mike about it. They were afraid and stopped swimming. Dick asked loudly,“Is it true that there aren’t any sharks in the river?”“Yes, sir,”said the boy,“there’re a lot of crocodiles(鳄鱼) in the water. All the sharks have swum away!”

In northern China during spring, big sandstorm often make trouble for people. Sandstorms usually happen in spring. They have happened in more than 10 provinces in northern China this year. People in southern China don’t have to worry about this kind of bad weather. Most of the sand comes from the north of China. In northern China, lots of places have few trees and don’t get much rain. When there aren’t many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts, the ground becomes loose. Strong winds take the loose sand into the sky. Besides, in northeast China, there lies some vast deserts.
Sandstorms are bad for people’s health. If people breathe in too much sand, they will cough or have serious illnesses. Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never come back home. The winds also tear the farmers’ houses down.
What can you do to stop sandstorms? Here’s a piece of advice. Ask your parents to help you plant some trees this spring. If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them.
