Green Plants and Deserts
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 crops. They are learning a lot about the deserts. But more and more land of the earth is becoming deserts all the time. Scientists may not be able to change the deserts in a short time.
Why is more and more land becoming deserts? Scientists think it is the people who make more and more deserts. People do bad things to the earth.
There is little rain in some places of the world. But these places don't become deserts because some green plants are growing there. Green plants are important to dry places. Plants prevent the hot sun from making the earth even drier. Plants don't let the wind blow the dirt away. When rain falls, the plants hold the water. Without the plants, the land will become deserts much more easily.

Dear Donna, Help! I’m a 15—year—old high school student in New York, In eight months, I’m going to take an entrance exam. To prepare, I’m studying six hours a day. I want to do well, but I’m really stressed(焦虑不安的) these days. I can’t sleep. What can I do? Yours, Mary |
Dear Mary, Many students around the world have the same problems as you. Here is some advice to help you deal with the street. Good luck! 1.Make a study plan for yourself, but don’t study too much in one day. You remember more by studying one hour each day for six days, than six hours in one day. Also, don’t study late at night. 2.Have a rest for 15 to 20 minutes every two hours. Go outside and walk. Doing exercise is a great way to reduce stress. 3.Don’t eat for drink a lot of sugar or drink a lot of coffee. Eat food high in vitamin(维生素) B (for example, eggs, milk, green vegetable and rice). These give you energy and help you think more clearly. 4.A student partner can help you practice for the test. When you’re worried about the exam, you can talk to your partner. This can reduce stress, too. Yours, Donna |

You may have known several kinds of police --- traffic police, fire police and street police. But have you ever heard of energy-saving(节能) policeman?
A group of 22 energy-saving policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and other public places. One of their aims is to make sure that these places have set their air conditioning(空调) no cooler than 26℃.
They also set up a special phone line so that people can tell them which buildings fail to follow the rule.
“If everyone sets their air conditioning at 26℃, Beijing will save 400 million kilowatthour of electricity in one summer. That’s one-third of all the usages of the city in the season,” said a TV advertisement.
Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiansu Province, are going to follow Beijing’s steps in setting up a similar police team.
As one of the fastest developing countries, China is using a lot of energy. This has a great effect on the country’s environment and limited(有限的) energy.
From 1986 to 2005, the country experienced 20 warm winters continuously(连续). Numbers show that Chinese cities have to spend billions of yuan solving environmental problems every year.
At the beginning of this month, China made its first action plan to fight pollution. It aims to reduce energy usage by 20% and increase renewable(可更新的) energy up to 10% from 7% by 2010.
To introduce the public to a green life, last week Beijing held a show on energy-saving technology and productions. Environment-friendly machines, such as a vending machine that helps collect used bottles, have attracted lots of attention. “We want to tell people that there are certain ways to protect the environment. Each of us can find effective ways to do it on our daily lives,” said Liu Qianguang, an environmental engineer in Beijing.
