thirst while waiting for a passing plane that never comes.
But don"t dismiss the thought as a nightmare (噩梦). Your hometown could become a desert if nothing
is done to prevent it.
Deserts are eating land at high speed. In China, desertification (沙漠化) has affected 2,622,000 square
kilometres, equal to 14 Guangdong Provinces, mostly in the North. Deserts are advancing at a pace of 2,460
kilometres per year.
According to the UN, one-third of the planet"s land surface, with one billion people, has become desert.
Africa, Asia and Latin America have the driest land in danger of desertification.
Recognizing the threat (威胁) to human beings, the United Nations has named 2006 the International
Year of Deserts and Desertification.
It wants to increase public awareness (关注) of advancing deserts. Activities include a film festival in
Rome with films on life in unproductive (贫瘠的) lands. Meetings will discuss international cooperation, such
as planting trees and changing agricultural practices.
Desertification takes place where rain is little and the climate hot. But human activities are the biggest
cause. Land turns into desert when the soil is over-farmed and too many animals eat up plants. To make
money, people also cut down trees that hold the soil. Desertification brings serious problems. From 1991 to
2000, droughts (干旱) killed over 280,000 people worldwide. When land becomes useless, there"s a big loss
in food production.
Dust from deserts is blown into cities around the world. Each spring, Beijing is at risk of yellow dust
from the Gobi Desert. Dust from Africa reaches cities in the US and Europe, leading to illnesses and
worsening environments.

| Many places in the world need fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren"t there many factories like the Symi factory? In some places, the sun is not hot enough. Or it does not shine every day. In such places, other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat, a lot of fresh water can be made quickly. But heating is not the only way to get fresh water from salt water. Other ways are tried. One way is freezing. The fresh part of salt water freezes first. To get fresh water, the bits of ice are taken out. Which way is the best? The one gives the most water for the least money. It may be a different way for each place. Symi"s way seems very good for small, hot places. It does not make very much water at a time. But the factory is easy to build and costs little. That is why people in many dry places talk about Symi! | |

| [ ] | |
| A. is needed in every country B. can be found in many factories C. can be used in many ways D. is very important for factories | |
| 2. What is the writer mainly talking about in the passage? | |

| When Christie Andrews was born, she weighed less that half of one kilogram. Her heart was the size of a large coin. Her mother said Christie was so small that she could hold her in the palm of one hand. Christie couldn"t breathe without a machine to give her oxygen. If she had been born 20 years earlier, she would probable have died at once. She needed two operations, but she survived without serious damage. Twenty years ago, 90% of all premature (早产) babies died. Today, doctors manage to save four out of every five, because they have better machines for breathing and better ways to feed the babies. But saving Christie"s life cost more than 400,000. In some cases, doctors spend 1 million saving a single child. The parents usually don"t have enough money to pay. Either the government, an insurance company or the hospital picks up (支付) the bill. Even after a baby goes home from the hospital, it may require medical care. Some people think it makes more sense (更合乎逻辑) to spend money saving 10 adults who have cancer or other diseases than saving one small baby. But nobody wants to be the doctor who has to tell parents to their faces, " Sorry, I won"t save your new child." | |

| Dear Wei Lin: It was really good to hear from you again, but I was surprised to learn that you started smoking soon after you went to the U.S. You said that smoking helps you relax. This might be true, but there are better ways to relax . And doctors tell us that smoking can only help us relax for a short time. I remember when you were in Taiwan, you were afraid that the air pollution might harm (对...有害处) your health. But don"t you think you"re also harming your health when you smoke? Smoking can hurt other people"s health, too. And I"ve heard that some people have gotten cancer from second-hand smoke. So for your own health and for the health of others, please give up smoking … Yours, Alex |
