The most widespread fallacy of all is that colds are caused by cold. They are actually caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in the isolated Arctic Regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty rooms. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose. If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on. No one has yet found a cure for the cold. There are drugs and pain suppressors such as aspiring, but all they do is relieve the symptoms. The passage mainly discusses ()
A. the experiments on the Common cold
B. the viruses of the common cold
C. the reason and the way people catch colds
D. the continued spread of common colds

Drunken driving- sometimes called America’s socially accepted form of murder- has become a national epidemic (流行病) . Every hour of every day about three Americans on average are killed by drunken drivers. A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American man image and judges were tolerant in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers more than doubled, so the state recently upped it back to 21. Reformers, however, fear raising the drinking age will have little effect unless accomplished by educational programs to help young people to develop "responsible attitudes" about drinking and teach them to resist pressure to drink. Tough new laws have led to increased arrests and tests and, in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks. A tavern (酒店主) in Massachusetts was fined for serving six or more double brandies to a customer who was "obviously intoxicated" and later drove off the road, killing a nine-year-old boy. As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition of alcohol that began in 1919. They forget that legal prohibition didn’t stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution. Statistics issued in New Jersey suggested that______
A. many drivers were not of legal age
B. young people were often bad drivers
C. the level of drinking increased in the 1960s
D. the legal drinking age should be raised
