When did you see a polar bear ? On a trip to a zoo, perhaps ? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These  “Polar Bears” are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3 degrees. And the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.

Doctors don’t agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body’s temperature drops so slow that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and the water tempreature is much greater in summer than in winter.

The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system (循环系统) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and could not try cold-water swimming.

The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, “When I go into the water, I pour my troubles into the ocean and let them float away.”

All over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer.

Sports change with the season. People play different games in winter and summer.

Games and sports often grow out of people’s work and everyday activities. The Arab use horses or camels in much of their daily life; they use them in their sports, too.

Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers.

Some sports or games go back thousands of years, like running or jumping. Chinese boxing, for example , has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time.

People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person’s character(性格品质). One learns to fight hard but fight fair, to win without pride and to lose with grace（体面）.
