The common cold is the world’s most widespread illness, which is plagues that flesh receives.
The most widespread mistake 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, 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 to relieve the symptoms.
The passage mainly discusses ______.

A:the experiments on the common cold B:the fallacy about the common cold C:the reason and the way people catch colds D:the continued spread of common colds

Colds are very common. The symptoms of the common cold include a sore throat, runny nose, stuffed-up nose, and tiredness. Colds are caused by viruses, but scientists cannot explain the exact cause. There is no cure. Many people, however, believe that they know the causes of and cures for the common cold. For example, they believe that it is possible to get a cold if we get chilled, if we get extra tired, or if we are too close to a person with a cold. In other words, if we want to prevent catching cold, we should stay warm and dry; we should avoid getting too tired, and we should not be in close contact with people who have colds.
Meanwhile, there are probably hundreds of " cures" throughout the world for the common cold. For example, the following suggestions are popular in quite a number of societies : (1) drink plenty of water; (2) get extra rest; (3) take a lot of vitamin C; (4) take aspirin; (5) keep warm.
Each year people spend a lot of money on cold medicines-pills, liquids, lozenges (含片). But these medicines do not cure colds; they can only relieve cold symptoms. In other words, they make us feel better.
The passage is mainly about ______.

A:looking for causes of the common cold B:introducing some cures for the common cold C:some facts about the common cold D:new medicines for curing the common cold
