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 the winter to swim in freezing cold water.That day,the air temperature was 3℃,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. 

Dcotors don't agree about the medical effects of cold-winter 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 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 should not try cold-water swimming. 

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

1.The members of the Polar Bear Club must meet the following requirements except that_____. 

2.According to the passage,some doctors believe it is true that_____. 

3.The Polar Bears like to swim year-round,for_____. 

4.The passage is mainly about_____. 

Swimming is one of those activities that can be learned early in life.Little children can learn to swim as soon as they walk.In fact,you need the same skills in walking as in swimming. However,I believe that five is the best age to learn.By five or six,a child knows fear of water,a very important thing to know.It's wise to be afraid,to recognize true danger.Young ones understand that the water can sometimes be very dangerous. 

To really benefit from swimming,every swimmer should learn,as soon as possible,these four basic strokes;butterfly,backstroke,breastroke,and crawl.I feel that one of these-the breaststroke-is different from the others,since some young swimmers use this stroke naturally,without any training. 

In swimming there are certain rules every swimmer should follow: 

1.Never swim alone!No matter how good you are in the water,don't risk drowning by swimming alone.If you swim by yourself,with no life guards or friends with you,you may get into trouble. 

2.Don't go beyond your abilities.Most swimmers know enough not to swim too far from the bank or the beach,Showing off by doing dangerous tricks is no good.  Swim safely and you will continue to swim and alive. 

3.Don't smoke.Swimming depends on a healthy body;good lungs are part of it. 

4.Work at any activity that builds muscles. 

1.Little children can learn to swim as soon as _____. 

2.The author believes that fear of water is_____. 

3.According to the passage,you should not swim alone because_____.
