The common cold is the world's most widespread illness, which is probably why there are more myths(神话) about it than any of the other illnesses.
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(感染的) people from the outside world by way of packages and mails dropped from airplanes.
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 doused(浸入) with cold water, and then stood about dripping(滴干)wet in drafty(通风的) 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 cold and wet have nothing to do with catching colds, why are they more frequent in the winter? In spite of the most painstaking 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.
Reducing the amount of sleep affects students' performance at school. An American study asked schoolteachers to look at the effects of sleep restriction（限制） on children between six and twelve years of age. The teachers found that children who stayed up late had trouble thinking clearly and had more learning problems.
{#blank#}1{#/blank#} Doctor Fallone now works at the Forest Institute of Professional Psychology in Springfield, Missouri. He presented the results last month at a science reporter conference in Washington, D. C. The Publication Sleep also reported the findings.
The teachers were asked to complete weekly performance reports on seventy-four schoolchildren. The study lasted three weeks. During that period, Doctor Fallone and his team controlled the amount of sleep the children received.
{#blank#}2{#/blank#} During another week, every child was kept awake later than normal. Each night, the youngest boys and girls had less than eight hours of sleep. The older ones were limited to six and a half hours. During the final week of the study, each child received no less than ten hours of sleep a night.
The teachers were not told about how much sleep the students received. The study found that students who received eight hours or less had the most difficulty remembering old information. {#blank#}3{#/blank#}
The study did not find that sleep restriction caused hyperactivity(极度活跃) in the children. {#blank#}4{#/blank#}
Doctor Fall one said that the results provided experts and parents with a clear message: {#blank#}5{#/blank#}
A. The sleeping time that the students have can be changed easily. B. They also had trouble learning new information, completing difficult work and following directions. C. During one week, the children went to bed and awoke at their usual time. D. The teacher should restrict the amount of sleep of the students. E. Gahan Fallone did the study at the Brown Medical School and Bradley Hospital in the state of Rhode Island. F. The teachers reported that students were, in fact, a little less active at school when they got less sleep. G. When a child has learning problems, the issue of sleep must be considered among the possible causes. |
