问题     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. [br] Arctic explorers may catch colds when ______
选项 A、they are working in the isolated Arctic Regions
B、they are writing reports in terribly cold weather
C、they are free from work in the isolated Arctic Regions
D、they are coming into touch again with the outside world
答案 D
