   The world itself is becoming much smaller by using modern traffic and modern communication means(交流方式). Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
   Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
   Air pollution is still the most serious. It's bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily.
    Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
   The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution.

Here in Siberia (西伯利亚), the winter is always very long and it's very, very cold! It starts to snow in November and the snow won't leave until May. The temperature is usually about -25℃, but it's sometimes much colder. When it's -35℃, children can't go to school, but grown-ups still go to work! We wear a lot of warm clothes: socks and boots, sweaters and fur coats. All the houses have heating, so it's never cold inside. In winter, we close the windows to stop the wind from getting in, and we don't open them again until spring.
In spring and summer it rains a lot, and we don't often see the sun. In summer it's often about 25℃, but the weather is very changeable. One day it's 25℃, and the next day it's 10℃. People say that the weather was even colder in the past.

   Arctic fox(北极狐) is a kind of small fox that lives in the Arctic. It grows about 50 centimeters long, not including its tail, 30 centimeters tall and weighs from 3 to 7 kilos.
   The Arctic foxes are white or blue in color. The white ones are white in winter, but grey-brown in summer. The blue ones are blue-grey all year round. The Arctic foxes have long, thick hair that is called fur. And the long fur covers their whole bodies, including both their cat eyes and rabbit feet, to keep them warm in the low temperature in the Arctic.
   The Arctic foxes feed mainly on birds, birds' eggs and other small animals. Teamwork is the way they look for food, and they don't like to do that alone.
   Baby Arctic foxes are very lovely. They don't open their eyes until a week after their birth. For the first half of the year, their parents offer them food. They begin to look for food on their own when they are about six months old. The next year they can live alone.
   Today, the number of the Arctic foxes is becoming smaller and smaller, because people kill them for their fur to make beautiful coats for money. Something must be done to protect the Arctic foxes.

Scientists have always believed that snails are not able to find their way home. But Briton Ruth Brooks, a retired teacher, has found that it is not true.

Brooks began an experiment on snails after she got mad with the snails in her garden.

The snails had eaten her vegetables. She didn't want to kill them, so she took them to another place. But she found they always seemed to come back.

Brooks did an experiment. She marked the snails in her garden with nail polish(指甲油).

She placed the snails in the area around her home and made notes of their movements.

She found that snails have a strong homing instinct (本能); the longest returning snail traveled back 90 meters. Brooks has been named Britain's best amateur (业余的) scientist after her work won the BBC Radio 4 project, So You Want To Be A Scientist.

She said, "I've always wanted to know whether the snails that eat my plants just come back when I move them, and if they do, what is their homing distance?

"I would say on the evidence (证据) that it would be safe to take your snails away beyond 100m or even further. If you put them somewhere nice with some food, you can be almost certain that they won't come back."
