Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and
there are pains all over your body. You don't want to work, you stay in bed, feeling very sad.
     What makes us ill? It is germs (细菌). Germs are everywhere. They are very small and you can't find
them with your eyes, but you can see them with a microscope. They are very small and there could be
hundreds of them on a very small thing.
     Germs are always found in dirty water. When we look at dirty water under the microscope, we shall
see them in it. So your father and mother will not let you drink dirty water.

dust from the floor goes into the cut (割开处), some of the germs would go into your finger. Your finger

     The common cold is the world's most widespread illness. The most widespread mistake of all is that
colds are caused by cold weather. 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 weather 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 (探险者) have reported being free
from colds until coming into contact again with the outside world by way of packages and mails
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 extremely surprised to
find that they seldom had colds.
     At the Common Cold Research Unit in England, volunteers took part in the 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 (often)
in the winter? Despite the most painstak- ing 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 colds. There are drugs and pain sup- pressors such as aspirin,
but all they do is to relieve the symptoms (症状).
