　　第一篇

Exercise Lowers Employers'Health Costs

　　Companies can save millions in health-care costs simply by encouraging their employees to exercise a little bit，researchers reported on Friday．

　　They said obese（肥胖的）employees had higher health-care costs，but lowered those expenses by exercising just a couple of times a week-without even losing any weight．

　　Feifei Wang and colleagues at the University of Michigan studied 23，500 workers at General Motors．

　　They estimated that getting the most sedentary（惯于久坐的）obese workers to exercise would have saved about$790，000 a year，or about 1．5 percent of health-care costs for the whole group.

　　Company-wide．the potential savings could reach$7 1 million per year，they reported in the Journal of Occupational and Environmental Medicine

　　Of the whole group of workers．about 30 percent were of normal weight，45 percent were overweight（超重的），and 25 percent were obese．Annual health-care costs averaged$2，200 for normal weight，$2，400 for the overweight，and$2，700 for obese employees．

　　But among workers who did no exercise，health-care costs went up by at least$100 a year，and were$3．000 a year for obese employees who were sedentary

　　But adding two or more days of light exercise——at least 20 minutes of exercise or work hard enough to increase heart rate and breathing——lowered costs by on average$500 per employee a year，the researchers found.

　　"This indicates that physical activity behavior could reduce at least some of the harmful effects of excess body fat，and in consequence，help lower the health-care costs，"Wang and colleagues wrote．

　　31 How can employees help lower the health-care costs?

　　A By taking more rest

　　D $7,300 per year．

　　33 How many workers in General Motors were NOT of normal weight?

　　C Forty-five percent

　　D Twenty-five percent．

　　34 For which group of the workers were the health-care costs the highest?

Medical Education

　　In 18th．century colonial America，those who wanted to become physicians either learned as personal students from established professionals or went abroad to study in the traditional schools of London，Paris{and Edinburgh．Medicine was first taught formally by specialists at the University of Pennsylvania，beginning in 1765，and in 1767 at King's College（now Columbia University），the first institution in the colonies to give the degree of doctor of medicine．Following the American Revolution，the Columbia medical faculty（formerly of King'S College） was combined with the College of Physicians and Surgeons，chartered in 1809，which survives as a division of Columbia University．

　　In 1893 the Johns Hopkins Medical School required all applicants to have a college degree and was the first to afford its students the opportunity to further their training in an attached teaching hospital．The growth of medical schools attached with established institutions of learning went together with the development of proprietary（私营的）schools of medicine run for personal profit．most of which had 10W standards and poor facilities In 1910 Abraham Flexner. the American education reformer, wrote Medical Education in the United States and Canada，exposing the poor conditions of most proprietary schools Subsequently the American Medical Association（AMA）and the Association of American Medical Colleges（AAMC）1aid down standards for course content，qualifications of teachers，laboratory facilities，connection with teaching hospitals，and licensing of medical practitioners（开业医师）that survive to this day．By the late 1980s the US and Canada had 142 4．year medical colleges recognized bv the Liaison（联络1 Committee on Medical Education to offer che M．D．degree；during the 1987-88 academic year,47,262 men and 25,686 women entered these colleges and an estimated 11，752 men and 5，958 women were graduated．Graduates，after a year of internship（实习期），receive licenses to practice if they pass an examination given either by a state board or by the National Board of Medical Examiners
