There are about 80.000.000 mines under the ground in more than 60 countries. It is difficult and dangerous to clear these mines.About 50 people including many children were killed or hurt each day.In 2003，APOPO，a Duch research company that trains the animals,came up with the idea of using rats to search for the mines.
The animal trainers found that a kind of rats from Africa were clever and had a sharp sense of smell.The rats were about 75 cm long and weighted about 1.35 kg.light enough to run across a minefield without setting off the mines.
In January 2004，the APOPO startec this preject.First ,the trainers let the 4-week-old baby rats get familier with humans. A few weeks later，the rats were no longer afraid of people and the things around them.Then they were trained to connect a click sound with food.After the rats had learned that ,the trainers then taught them to tell the different between the smell of mines and other smells.When the rats could do it，the click was sounded and they were given a bit of bananas.The method was called clicker training.“The training isn’t easy.”said the trainer Adulish Mebomvu.“You have to be patient.Sometimes I get angry,but then again.I tell myself these are animals.”
After nine months’ training,the rats were taken to 4 minefield. They ran across the minefield ,stopped, sat and searched the ground to tell the deminers that they smelt out a mine. Then the mine was cleared.It had taken two deminers a day to clear a 200 m2 minefield. But with the help of two rats they could finish it in two hours.
The rats and the deminers saved thousands of lives.“The rats did this job much better than we expected.So far they have helpde to make almost 2.000.000 m2 of land safe.They are heroes.”said Bart Woetjcds.the head of the APOPO.

A thousand years ago Hong Kong was covered by a thick forest. As more and more people came to 1 in Hong Kong, these trees were cut down and burnt. Now there is 2 forest left, though there are still some small areas covered in trees．We call these woods.
Elephants, tigers and many 3 animals were living in the thick forest. When people came to live in Hong Kong, the 4 began to die out. Early farmers grew rice and 5 pigs and chickens in the valleys. They cut down the trees and burnt them. They needed 6 to keep themselves warm in winter, to cook their food and to keep away the dangerous animals.

At 9 a.m. on October 15, 2003, our country launched (发射) its first manned (有人的) space-ship, Shenzhou V, into space at Jiuquan Satellite Launch Center in Gansu Province. It took Yang Liwei and his spaceship about 21 hours to circle the earth 14 times. Yang Liwei is China’s first astronaut. He comes from Liaoning Province, and he has been an air force pilot(飞行员) since 1983. He was chosen from 14 pilots after many difficult tests.
The life of an astronaut is hard to imagine for many people. To put on a space suit takes 15 minutes with the help of others. Sleeping in space is not easy, either. He has to sleep in a special sleeping bag on the wall because there is no gravity. Yang can eat chicken and rice. It’s especially made to eat in space but it doesn’t taste nice.
“I’m feeling very good in space, and it looks wonderful here,” said Yang, “I have looked at our beautiful earth and I have recorded all that I have seen here.”
China has become the third country in the world to send a person into space after the former Soviet Union(前苏联) and the United States. China is now planning its next launch. Shenzhou VI will be into space within(在……之内) the next years, it may take three astronauts. We are all proud of our motherland.

Then the number grew very quickly. From 1815 to 1915, over 32,000,000 Europeans left their countries for the United States. The biggest groups went from Germany and Italy.

Want to stay away from colds? Put on a happy face.
Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It"s possible that being happy helps the body fight illnesses, say the researchers from New York University.
"It seems that positive feelings may reduce the danger of illness," said the study"s chief researcher Sheldon Cohen.
In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed feelings were also less likely to tell their doctors that they felt ill.
In this study, Cohen"s interviewed 193 adults every day for two weeks. During the interviews, the people were given colds by doctors and had to stay alone in a room for six days.
The results showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness are less serious and lasted for a shorter time.
Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.
