单项选择题
When did you last 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 winter to swim in freezing cold water. That day, the air temperature was 3℃, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two require-ments. 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 do not 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 low 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 water temperature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits (or advantages)of cold-water swim-ming. 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 circula-tory system and should not try cold-water swimming.
The main benefits ( or advantages) of cold-water swimming are probably mental. The Polar Bears love to swim 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. "

Cats are creatures of habit. They like to go to sleep about the same time every day and for a certain length of time. They seem to have a natural clock inside them that tells them when to sleep.
Cats increase their regular sleep with occasional cat naps (打盹). Some experts feel that humans could also benefit from this habit. Cat naps help to build up energy in the body. They are also a good way to get rid of trouble ！ Since cats have the same moods ( 情绪) as humans, some experts believe that people can improve their moods. People might become happier.
A number of famous people have copied cats by taking cat naps during the day. The naps would usually last from 15 to 30 minutes.
Winston Churchill took cat naps. So did Presidents Harry Truman, John F. Kennedy and Lyndon B.
Johnson. These famous men were known for their energy. They were also able to work long hours, often into the night. Napping was their secret.
