In the past my hometown was used to be a beautiful place. Thick trees and green grass could be seen in everywhere. In order to build house and grow more crops, people cut down more and more trees. With time went on, the whole forest was almost destroyed. Gradually the green hills have changed into wasteland. As a result, sandstorms struck us now and then, of which we suffer a lot. However, I do hope all the people should realize the terribly result of not caring about our environment. What's more, they should take good care of the forests and plant trees instead cutting them down to improve our living conditions.

“HEARTLESS”— a word you wouldn’t want to use to describe a person. But having his heart removed was what saved Craig Lewis’ life—and what made him the first living “heartless” man.
The 55-year-old，dying of heart disease，was told he only had 12 hours to live， when Billy Cohn and Bud Frazier, doctors from the Texas Heart Institute, decided to try something new. They removed Lewis heart and replaced it with an artificial (人造的) one. Less than a week after the operation, Lewis was able to sit and speak.
Lewis kept on living like a normal person, with only one difference—he didn’t have a heartbeat. The human heart usually pumps blood through our bodies by beating regularly. By contrast, this artificial heart pushes the blood forward with two moving blades(桨叶). If you were to touch Lewis or listen to his chest, you would not feel a heartbeat. If you hooked him up to an EKG(心电图) machine, the line would be flat.
Scientists have been trying to create a working artificial heart for years. Until now, all artificial hearts either broke down or caused blocks and infections.
But after five years of hard work, Dr Cohn and Dr Frazier developed this artificial heart. It is smaller and quieter than other artificial hearts and can last much longer. They tested it on 38 calves (牛犊) and all of them turned out energetic and healthy. Lewis is the first human proof that the machine is a success.
The doctors will have to work more on the device and decide on a final design before it can be widely used. The US Food and Drug Administration will also need to say that the machine is safe. But this artificial heart looks likely to bring a ray of hope to thousands of patients.
