Question

20．The most widespread fallacy（謬論）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 people are free from colds until they come into contact again with infected people from 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（戰(zhàn)壕），cold and wet，showed no increased tendency to catch colds．
In the Second World War prisoners at the Auschwitz concentration camp，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 in a drafty（通風良好的）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 times，and this makes it easier for cold viruses to be passed on．

Answer 1

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了寒冷和潮濕與感冒的關系，感冒不是寒冷引起的，是人與人之間傳播的病毒引起的．

解答 41．B   細節(jié)理解題．根據(jù)第 1 段的兩個例子、第 2 段的一個例子和第 3 段的兩個例子可知B為正確選項．
42．D   細節(jié)理解題． 根據(jù)第1段的"You catch a cold by coming into contact，directly or indirectly，with someone who already has one．"可知選項D正確．此題同學們可能會誤選C，根據(jù)最后一段"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．"可知人們得感冒不是因為喜歡呆在家里，而是因為經(jīng)常呆在一起病毒更容易感染，故可排除 C；故選D．
43．D   細節(jié)理解題．由第1段的"And in isolated arctic regions explorers have reported people are free from colds until they come into contact again with infected people from the outside world by way of packages and mail dropped from airplanes．"可知，北極地區(qū)探險者是因為與外界接觸后才得感冒的，故選 D．
44．A  細節(jié)理解題．由第3段的"After taking hot baths，they put on bathing suits，allowed themselves to be with cold water，and then stood about dripping wet in a drafty（通風良好的） room．Some wore wet socks all day while others exercised in the rain until close to exhaustion．"可知，志愿者要遭受極大的痛苦，故選 A．
45．C   主旨大意題．閱讀全文可知，本文首先用大量事例從不同的側面分析感冒不是由寒冷引起的，最后提出冬天得感冒的可能原因．由此可知 C 為正確答案．

點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
