Scientists are trying to make the deserts into good land again. They want to bring water to the deserts so that people are can live and grow food.They are learning a lot about the deserts. But more and more of the earth is becoming deserts all the time. Scientists may not be able to change the deserts in time.
Why is more and more land becoming deserts? Scientists think that people make deserts. People are doing bad things to the earth.
Some places on the earth don't get very much rain, but they still don't become deserts. This is because some green ants are growing there. Small green plants and grass are very important to dry places. Plants don't let the hot sun make the earth even drier. Plants don't let the wind blow the dirt(泥土)away. When a little bit of(一点儿)rain falls, the plants hold the water. Without plants, the land will become deserts much more easily.

Sandstorms have a great effect on many Asian countries for centuries. Scientists have tries many ways to solve this problem and so have people in China.
In the world. there are four main places where the sandstorms happen. They are Central Asia, North America. Central Africa and Australia.
Northwest China is part of the sandstorm centre in Central Asia. Sandstorms begin in desert areas.
Sandstorms in China appear more often because of climate changes and because people cut down trees and dig up grass. They sometimes affect Beijing. People wake up in the morning to find an orange sky and strong winds with thick, brown-yellow dust covering the whole city.
The storms sometimes last all day and traffic moves very slowly because the thick dust makes it difficult to see.
When a sandstorm arrives in the city, people had better not go out.Huang Xiaomei, who lives in Beijing, says, Cycling in a sandstorm is terrible. The winds are very strong. It's difficult to breathe and the dust makes me ill. So if you want to go out，you'd better wear a mask（口罩）．”
The desert is only 250 kilometres away to the west of Beijing. To prevent it coming nearer, the government is planting trees.
So far, the government has already planted more than 30 billion trees and plans to continue planting for the next five years. People hope it can help.

Have you seen some machines that eat used plastic bottles and give some coins to the users?
Recently, such machines have appeared at universities in Chongqing. They can turn rubbish into treasure and encourage the public to recycle rubbish. The machine is as large as a fridge. Users put an empty bottle in the machine. It is identified (识别 )by a small camera. Then it is put into a built-in bin. The users can get some coins. They can also give away the money.
When the machine is filled with bottles, it will tell the company's head office. Nearby stations will send workers to have bottles collected. They pack and send them to the company.
The bottle recycling machines have greatly encouraged the public to recycle rubbish and saved natural resources. Now the machine only eats plastic bottles. At sometime in the future it will also cover others, such as glass bottles to turn more rubbish into treasure and make full use of the natural resources.
People can also see similar machines in Shanghai. In the future, more and more such machines will appear at some large stations. Bus stops, neighborhoods and schools may have a long way to go.
