单选题The common cold is the world"s most widespread illness, which is probably why there are more myths about it than any of the other plagues (瘟疫) that flesh is heir to. The most widespread fallacy (谬误，谬论) of all is that colds are caused by cold. They are not. They are caused by viruses passed 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 permanently. 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, was astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in experiment in which they submitted 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 (浸泡) 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 prevalent in the winter? Despite 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 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 such as aspirin, but all they do is relieve the symptoms.

单选题Questions 57 to 61 are based on the following passage. "The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind. " So said Sigmund Freud. Today,most researchers reject his belief that dreams are expressions of our unconscious desires, but the fascination with why we dream is stronger than ever. Dreams are not meaningless, and they are certainly not useless. For a start, they are crucial for processing emotions. "Dreams modulate the emotions--they keep them within a certain range," says Patrick McNamara of Boston University. New research has found that naps consolidate emotional memories-and the greater the amount of rapid-eye-movement(REM) dream sleep, the greater the processing of these memories. One idea is that REM dreams allow us to relive powerful emotional memories, but without the rush of stress hormones that accompanied the real experience. In this way, we keep the memory but the emotion accompanying it gradually lessens. REM dreaming also helps other types of memory and problem solving. People are better able to recall lists of related words and the connections between them after a night's sleep than after the same time spent awake during the day. It has recently become apparent that not all dreaming occurs in REM sleep, and there are hints that non-REM dreams have their own special function. By waking students during both REM and non-REM sleep, McNamara and colleagues have discovered that REM dreams are more story-like, with more emotion, more aggression and more unknown characters than non-REM dreams, which often involve friendly social interactions. McNamara thinks that by simulating aggressive encounters, REM dreams help us cope with real aggression,whereas non-REM dreams support cooperative behavior. The content of dreams can be influenced by external factors such as scents, or even the Earth's geomagnetic field, but there seem to be some reoccurring themes. Many REM dreams contain unknown males, usually in aggressive social interactions with the dreamer. The discovery of universal themes could predict a return to the study of the meaning of dreams, this time based on science. "It suggests that a certain kind of dream interpretation may be possible," McNamara says.
