   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.
