     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.
