The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.

The most widespread fallacy(谬误) 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 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(战壕), cold and wet, showed no increased tendency to catch colds.

In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), 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(止痛片) such as aspirin, but all they do is relieve the symptoms.

Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contract relationship with one or more hospitals in the community. They send their patients to this hospital, which usually charges patients according to the number of days they stay and the facilities(operating room, tests, medicines that they use). Some hospitals belong to a city, a state or, in the case of veteran's hospitals, a federal government agency. Others are operated by religious orders(教会) or other non-profit groups.

Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service.

Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $ 100 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would be physicians first attend college for four years, which can cost nearly $ 20 000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $ 10 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency(实习阶段) in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low.

Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies.

Physicians work long hours and must accept a great deal of responsibility. Many medical procedures, even quite routine ones, involve risk. It is understandable that physicians want to be well rewarded for making decisions which can mean the difference between life and death.

4. Sometimes several physicians set up a group medical practice mainly because _______.

A. there are so many patients that it is difficult for one physician to take care all of them

B. they can take turns to work long hours

C. facilities may be too much of a burden for one physician to shoulder

D. no one wants to assume too much responsibility

5. Which of the following statements could fully express the author's view towards physicians’ payment in the USA?

A. For their expensive education and their responsibility, they deserve a handsome pay.

B. It is reasonable for physicians to have a large income because their work is very dangerous.

D. Physicians have great responsibility, so it is understandable that they should be well rewarded.

The Internet has led to a huge increase in credit-card fraud. Your card information could even be for sale in an illegal web site.

And shop only at secure sites; Send your credit-card information only if the Web site offers advanced secure system.

If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The Website address may also start https: //—the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.

Keep your password safe: Most on-line sites require a user name and password before placing an order. Treat your passwords with care.
