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.
Volunteers of the experiments in the Common Cold Research Unit______
选项 A、suffered much from coldness
B、never caught colds
C、always caught colds
D、became very strong
答案A
解析 根据文章第二段“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．”可知，在英格兰的常见感冒研 究小组中，志愿者们参加实验，他们长期忍受寒冷和潮湿带来的不适。洗了热水澡以后，他 们穿上游泳衣，让自己泡在冰凉的水中，然后站在附近通风的房间里沐浴。一些人整天穿湿 袜子，而另一些人在雨中锻炼身体，等到快筋疲力尽才肯罢休。没有一个志愿者因此感冒， 除非感冒病毒落入他们的鼻子里。所以，志愿者们遭受了很大的寒冷。但是在接触感冒病毒 的条件下他们也可能感冒。据此判断，答案是A。
