The common cold is the world's most widespread illness, which is plagues (瘟疫) that flesh receives. The most widespread fallacy (谬误) of all 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, 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 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 (战壕) cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp (奥斯维辛集中营), 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 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 dipped with cold water, and then stood about dripping wet in drafty room. 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-killer pills such as aspirin, but all they do is relieve the symptoms.

(答案→)B 解析：文章主要讨论的是人们患感冒的原因，主要是因为病毒感染。【小题1】B 细节题。文章第二段举了两个例子，第三段举了两个例子，第四段举了一个例子，共5个。B正确。【小题2】C 细节题。文章第二段提及爱斯基摩人很少感冒。第一段中告诉我们感冒并不是由寒冷引起的。C的说法是错误的，人们感冒就是因为人们喜欢带着房子里面。实际上人们感冒是因为病毒感染。故C符合要求。【小题3】D 细节题。根据第二段2,3,4行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说明D正确。【小题4】A 细节题。根据第四段2,3,4行内容可知他们受了很多苦，故A正确。【小题5】C 主旨大意题。文章主要讨论的是人们患感冒的原因，主要是因为病毒感染。
