    　　Scientists are trying to make the deserts (沙漠) into good land again. They are learning a lot about them, but more and more land 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? People make deserts. They are doing bad things to the earth.

    　　There isn't much rain in some places on the earth, but still they don't become deserts. Why? Because some green plants and grass are growing there and they are very important to dry places.
