Question

The common cold is the world's most widespread illness, which is a serious infection that man receives.

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 touching 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 separate Arctic (北極的)areas, explorers have reported being free from colds until touching 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, seldom caught colds.

In the Second World War, prisoners at Auschwitz concentration camp, bare and starved, 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 a long 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 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 winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that 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-killers such as aspirin, but all that they do is to reduce the symptoms.

試題分析：本文介紹了人們感冒的原因和患上敢買的途徑。

1.D 細(xì)節(jié)題。根據(jù)第二段第二句They are caused by viruses passing on from person to person.說(shuō)明D正確。

2.D 細(xì)節(jié)題。根據(jù)第二段后三行And in separate Arctic (北極的)areas, explorers have reported being free from colds until touching again with infected people from the outside world by way of packages and mail dropped from airplanes.說(shuō)明這些人在北極沒(méi)有感冒，與病毒接觸以后才會(huì)感冒，故D項(xiàng)正確。

3.A 細(xì)節(jié)題。根據(jù)第五段volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for a long 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 room. Some wore wet socks all day while others exercised in the rain until close to exhaustion.說(shuō)明這些志愿者在這次活動(dòng)中受了很多的折磨，故A正確。

4.C 主旨大意題題，本文主要講述的就是感冒不是由寒冷引起的，而是由病毒的傳染引起的。文章中的多個(gè)例子都有力地證明了這一點(diǎn)，故文章講述的就是感冒的原因和途徑。C項(xiàng)正確。

考點(diǎn)：考查科普類短文

點(diǎn)評(píng)：本文所設(shè)試題主要考察細(xì)節(jié)查找，對(duì)于文章中的細(xì)節(jié)題，要注意文本內(nèi)容的理解。關(guān)鍵是找出原文的根據(jù)，認(rèn)真核查題支和原文的異同，常犯錯(cuò)誤有：絕對(duì)化語(yǔ)言，范圍擴(kuò)大或縮小，以偏概全，張冠李戴等。帶著問(wèn)題，再讀全文，找出答題所需要的依據(jù)，完成閱讀。
