问题     The common cold is the world’s most widespread illness, which is probably why there are more myths about it than any of the other plagues that flesh is heir to.
    The most widespread fallacy of all is that colds are caused by cold. They are not. They are caused by viruses passed 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 permanently. But they do not. And in 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.
    During the First World War, soldiers who spent long periods in the trenches, cold and wet, showed no increased tendency to catch colds.
    In the Second World War, prisoners at the notorious Auschwitz concentration camp, naked and starving, were astonished to find that they seldom had colds.
    At the Common Cold Research Unit in England, volunteers took part in experiments in which they submitted 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 doused 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 prevalent in the winter? Despite the most painstaking 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 colds. There are drugs and pain suppressors such as aspirin, but all they do is to relieve the symptoms. [br] Which of the following is NOT true?
选项 A、The Eskimos seldom suffer from colds.
B、Colds are not caused by cold.
C、People suffer from colds just because they like to stay indoors.
D、A person may catch a cold by touching someone who already has one.
答案 C
解析 推理题 感冒是通过病毒传染的，呆在室内显然不应该是感冒的原因。倒数第二段最后一句人们易于在天冷的时候感冒是由于人们倾向于天冷时一起呆在室内，从而便于病毒传染。因此C项不正确。
