Common-Cold Sense

You can't beat it,but you don't have to join it. Maybe it got the name"common cold"because it's
more common in winter. The fact is,though,being cold doesn't have anything to do with getting one.Colds
are caused by the spread of rhinoviruses（鼻病毒）,and,at least so far,medical science is better at telling
you how to avoid getting one than how to get rid of one.
Children are the most common way cold viruses are spread to adults,because they have more colds than
adults一an average of about eight per year. Why do kids seem so much more easily to get colds than their
parents?Simple.They haven't had the opportunity to become immune to many cold viruses.
There are more than 150 different cold viruses,and you never have the same one twice.Being infected
by one makes you immune to it一but only it.
Colds are usually spread by direct contact,not sneezing or coughing. From another person's hand to
your hand and then to your nose or eyes is the most common route.The highest concentration of cold viruses
any where is found under the thumbnails of a boy,although the viruses can survive for hours on skin or other
smooth surfaces.
Hygiene is your best defense.Wash your hands frequently,preferably with a disinfectant soap,
especially when children in your household have colds.
But even careful hygiene won't ward off every cold.So,what works when a coughing,sneezing,runny
nose strikes?
The old prescription of two aspirins,lots of water,and bed rest is a good place to start.But you'll also
find some of the folk remedies worth trying. Hot mixtures of sugar(or honey),lemon,and water have real
benefits.
选项 According to the essay,you may have a cold because______.A:the weather is too coldB:the spread of rhinoviruses gets people infectedC:another person's coughing passes the cold to youD:you wash your hands too often
答案B
解析第一段虽然提到了感冒常发生子冬天，但紧接着提到，受凉并不会导致感冒，所以A项 不是正确答案。由文章第四段第一句可知，感冒通常是由于与感冒的人身体直接接触而导致 的，而不是由于打喷嚏或咳嗽传染的，所以C项也不是正确答案。D项歪曲文章意思，选项B 与第一段第四句的意义相吻合，因此是正确答案。 文章第五段第一句话“Hygiene is your best defense.”的意思是“卫生是你的最佳防御。” 因此A项是正确答案。在本段第二句提到的用消毒肥皂洗手，是保持卫生的手段之一。 第二段中提到儿童平均一年得8次感冒，这是一个统计数据而不是儿童得感冒的原因； 文中并没有说“儿童从不洗手”；文中也没有说“儿童不喜欢吃柠檬”；所以A、C、D三项都不 对。B项与第二段最后一句意思一样，是正确答案。 第三段提到有150多种感冒病毒，而人们绝不会被同一种病毒侵害两次，因为人得了一 次感冒后对相应的病毒就获得了免疫力，所以只有C项才符合第三段的内容。 文中并没有提到得了感冒就胃疼，实际上文中根本就没有“stomachache”这个词或相关 的字眼，所以D项是正确答案。第二篇 本篇文章主要讲述了睡眠不足是现代美国社会的通病。分析了造成睡眠不足的一些原因， 以及睡眠不足产生的后果，建议人们增加睡眠以保持精力旺盛。
