[单选题]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 3oC,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 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 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 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(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."
According to the passage,some doctors believe it is true that
A.you are healthy if cold-water swimming turns your skin color blue
B.cold-water swimming causes more heart attacks in summer than in winter
C.cold-water swimming can make the body temperature dangerously high
D.Polar Bears are bears swimming in freezing water

[不定项选择题]共用题干
Study Helps Predict Big Mediterranean Quake
1.Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.
2.Using radiocarbon dating techniques,simulations and computer models,the researchers recreated the ancient disaster in order to identify the responsible fault."We are saying there is probably a repeat time of 800 years for this kind of earthquake,"said Ms Beth Shaw,an earthquake scientist at the University of Cambridge,who led the study. Scientists study past earthquakes in order to deter-mine the future possibility of similar large shocks.
3.Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region,Ms.Shaw said.The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300,which means the next powerful one could come in the next 100 years,she added in a telephone interview.
4.Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion,she said.Their computer model suggested an 8 magnitude quake on the fault would pro-duce a tsunami that floods the coastal regions of Alexandria and North Africa,the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik.This would be similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta likely killing tens of thousands of people,she said.
Radiocarbon dating techniques can be used to identify the age of the earth.
A.Right
B.Wrong
C.Not mentioned
