Question

The common cold is the world’s most widespread illness, which is plagues(疫病) that people receive.
The most widespread fallacy(谬误) of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) 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 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 with cold water, and then stood about dripping wet（湿透）in drafty（通风的）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 time, 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(止痛片) such as aspirin, but all they do is relieve the symptoms

Answer 1

BDAC
根据文中第一段和最后一段可知文章通过实例证明感冒不仅仅是因为着凉。
1.细节理解题 从第二段到文章末段共用了五个例子。分别是第二段中的Eskimo人的生活，第二段中的一战，二战集中营，在the Common Cold Research Unit in England中志愿者的例子，以及倒数第二段中提到的实验这五个。所以选B
2.细节理解题 根据第二段中“...And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world...”可知只有通过和外界的接触后才会感冒。
3.细节理解题 根据第三段中“...volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time...”可知这些志愿者在这个实验中要经历很多。
4.主旨大意题 根据文中第一段和最后一段可知文章通过实例证明感冒不仅仅是因为着凉。
