问题     As we all know that the common cold spreads widely in the whole world. The most widespread mistake is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact 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 isolated Arctic regions explorers have reported being tree from colds until coming into contact again with infected people from the outside world.
    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, astonished took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of. time. Some 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 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 the cold. There are drugs and pain suppressors such as aspirin, but all they do is to relieve the symptoms.
The passage mainly discusses______.
选项 A、the experiments on the common cold
B、the fallacy about the common cold
C、the reason and the way people catch colds
D、the continued spread of common colds
答案B
解析 主旨题。第一段中“The most widespread mistake of all is that colds are caused bycold．They are not．”是本文的主题句。从而可以看出全文主要阐述了“感冒不是由寒冷引起的”这一观点。故答案为B。
