Scientists are trying to make the deserts into good land again. They want to bring water to the deserts， so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time.

Why is more and more land becoming desert？Scientists think that people make deserts. People are doing bad things to the earth.

Some places on the earth don’t get much rain. But they still don’t become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don’t let the sun make the earth even drier. Plants do not let the wind blow the dirt away. When a bit of rain falls，the plants hold the water. Without plants，the land can become desert more easily.

I do a lot of management training each year for the Circle K Company. Among the 21 we discuss in our classes is the 22 of quality employees（雇员）

Cynthia said she used to 25 a Circle K clerk job as an interim (时临的.) one while she looked for something 26 . On her second day behind the counter, she received a (an) 27 from her nine-year-old son, Jessie. He 28 a baseball glove for the little League. She 29 that as a single mother, money was 30 , and her first check would have to go for paying 31.

When Cynthia arrived for work the next morning, Partircia, the store manager asked her to come to her small office and handed her a box. “I overheard you 32 to your son yesterday,” she said, “and I know that it is 33 to explain things to kids. This is a baseball glove for Jessie. I know you have to pay bills 34 you can buy gloves. You know we can’t 35 good people like you as 36 as we would like to; but we do 37 and I want you to know how 38 you are to us.”
