    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,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-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-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 anywhere 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.

    Children have more colds because______.
    A:they are usually infected about eight times each year
    B:they are not immune to many cold viruses yet
    C:they never wash their hands so that their thumbnails are dirty
    D:they don't like eating lemon

    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.

    When you are having a cold,________.
    A:it is always the same kind of cold that you had last time
    B:it may be the same kind of cold that you had last time
    C:it is certainly not the same kind of cold that you had last time
    D:it is probably not the same kind of cold that you had last time

    答案:C
    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。

    Questions 11 to 15 are based on the following passage. Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症),a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one. Which of the following symptoms will distinguish the flu from a cold? ()

    • A、A stuffy nose.
    • B、A high temperature.
    • C、A sore throat.
    • D、A dry cough.

    Children are the most common way cold viruses are spread to adults,because they have more colds than adults-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-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 anywhere 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.

    When one is having a cold,he may often have all the following symptoms EXCEPT______.
    A:coughing
    B:sneezing
    C:having a runny nose
    D:having a stomachache

    答案:D
    解析:

    由文章第五段第一句可知,保持卫生是应对感冒的最好防御,故选A。
    由文章第二段最后一句可知,儿童对很多病毒还不具有免疫性,因此他们更易患感冒。故选B。
    由文章第三段内容可知,一个人绝不会被同一种感冒病毒感染两次,和C项的表述内容相符,故选C。
    由文章倒数第二段第二句的内容可知, 当一个人患感冒时,会出现咳嗽.打喷嚏以及流鼻涕的症状,而未提及有胃疼症状,故选D。

    请阅读 Passage 2,完成第 26~30小题。Passage 2 The common cold is the world's most widespread illness, which is plague that flesh receives.The most widespread fallacy of all is that colds 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 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, 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 drafty 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.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.The author cites the Eskimos not suffering from common colds forever to indicate ____.
    A

    C
