【正文】 tact,directly or indirectly,with someone who already has cold causes colds,it would be reasonable to expect the Eskimos to suffer from them they do in isolated arctic regions explorers have reported being free from colds until ing 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 （戰(zhàn)壕）,cold and wet,showed no increased tendency to catch colds.In the Second World War prisoners at the notorious Auschwitz concentration camp（奧斯維辛集中營）,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 disforts of being cold and wet for long stretches of taking hot baths,they put on bathing suits,allowed themselves to be with cold water,and then stood about dripping wet in drafty wore wet socks all day while others exercised in the rain until close to 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 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 are drugs and pain suppressors（止痛片）such as aspirin,but all they do is to relieve the symptoms（癥狀）. writer offered examples to support his argument. of the following does not agree with the chosen passage? Eskimos do not suffer from colds all the time. are not caused by cold. suffer from colds just because they like to stay indoors. person may catch a cold by touching someone who already had one. explorers may catch colds when . are working in the isolated arctic regions are writing reports in terribly cold weather are free from work in the isolated arctic regions are ing into touch again with the outside world taking part in the experiments in the Common Cold Research Unit . a lot cuaght colds caught colds very strong passage mainly discusses . experiments on the mon cold fallacy about the mon cold reason and the way people catch colds continued spread of mon coldsDIs language,like food,a basic human need?Judging from the result of the violent experiment by a German Ⅱ,in the 13th century,it may to discover what language a child would speak if the heard no mother tongue,he told the nurses to keep silent.All the babies died before the first clearly there was more than language deprivation was missing was good good mothering,in the first year of life especially,the capacity to survive is seriously affected.Today no such violent deprivation exists as that ordered by Frederick Ⅱ.Nevertheless,some children are still backward in often the reason for this is that the mother is insensitive（不敏感）to the signals of the baby,whose brain is programmed to map up language are critical times,it seems,when children learn more these sensitive periods are neglected（忽視）,the ideal time for gaining language skills passes and they might never be learned so easily again.Linguists（語言學(xué)家）suggest that speech stages are reached in a fixed sequence（順序）and at a constant age,but there are cases where speech has started late in a child who eventually turn out to be of high IQ.Recent facts suggest that baby is born with the capacity to is special about Man’s brain,pared with that of the monkeys,is the plex system which enables a child to connect the sight and feel of,say,a teddybear（玩具熊）with the sound pattern“teddybear”.But speech has to be stimulated（刺激）,and this depends on interaction between the mother and the child,where the mother recognizes the signals in the child’s babbling（牙牙學(xué)語）,grasping,crying and smiling,and responds to （不敏感）of the mother to these signals dulls（使遲鈍）the interaction because the child gets discouraged and sends out only the obvious to the child’s nonverbal signals in essential to the growth and development of language. II’s experiment was violent be
