阅读理解 The common cold is the world's most widespread illness, which is plague that flesh receives.
The most widespread fallacy of all is that colds 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, 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, 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 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 suppressors such as aspirin, but all they do is relieve the symptoms.

单选题 The author cites the Eskimos not suffering from common colds forever to indicate______.

【正确答案】 D

【答案解析】推断题。文章第二段说到，对于感冒，最普遍的谬论是感冒是由寒冷引起的，后面说到实际上并不是这样，“If cold causes colds，it would be reasonable to expect the Eskimos to suffer from them forever．”，由这里可知，作者的意思是，如果寒冷可以造成感冒，那一直忍受寒冷的爱斯基摩人一定会一直都在感冒。即用这个例子验证寒冷不会引起感冒。故选D。

单选题 Which of the following does not agree with the passage?

【正确答案】 C

【答案解析】细节题。同上题，爱斯基摩人不会一直感冒，且感冒不是由寒冷引起的，故A、B两项与文章相符。文章第二段提到生活在北极圈与世隔绝的人们一直都不会得感冒，直到他们与感染了感冒病毒的人接触。故可知D项与文章相符。作者在倒数第二段中说冬天感冒人多的原因是冬天人们更愿意一起待在屋里，这样感冒病毒很容易在人与人之间传播，而单纯地待在屋里不会得感冒，故C项错误。

单选题 Arctic explorers may catch colds when______.

单选题 Volunteers taking part in the experiments in the Common Cold Research Unit ______.

【正确答案】 A

【答案解析】细节题。本题的考点在第四段，根据描述，这些志愿者在洗完热水澡后，穿上泳衣，在自己身上浇凉水，然后站在通风的房间里，还有些人穿着湿袜子，站在雨中，以检测他们会不会得感冒。结果证明所有人都没有得感冒，直到他们接触了病毒。故B、C、D三项错误，只有A项正确。
