单选题The Doctor in America Self-employed private physicians who charge a fee for each patient visit have been the norm for American medical practice. Most physicians have a contract relationship with one or more hospitals in their community. They refer their patients as needed to the hospital, which usually charges according to the number of days a patient stays and the facilities—X—rays, operating rooms, tests—he or she uses. 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 (住院医生实习期) 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.

单选题 Diseases of Agricultural Plants Plants, like animals, are subject to diseases of various kinds. It has been estimated that some 30,000 different diseases attack our economic plants; forty are known to attack corn, and about as many attack wheat. The results of unchecked plant disease are all too obvious in countries which have marginal food supplies. The problem will soon be more widespread as the population of the world increases at its frightening rate. Even in countries which are now amply fed by their agricultural products there could soon be critical food shortages. It is easy to imagine the consequences of some disastrous attack on one of the major crops; the resulting famines could kill millions of people, and the resulting hardship on other millions could cause political upheavals disastrous to the order of the world. Some plants have relative immunity to a great many diseases, while others have a susceptibility to them. The tolerance of a particular plant changes as the growing conditions change. A blight may be but a local infection easily controlled; on the other hand it can attack particular plants in a whole region or nation. An example is the blight which killed virtually every chestnut tree in North America. Another is the famous potato blight in Ireland in the last century. As a result of that, it was estimated that one million people died of starvation and related ailments. Plant pathologists have made remarkable strides in identifying the pathogens of the various diseases. Bacteria may invade a plant through an infestation of insect parasites carrying the pathogen. A plant can also be inoculated by man. Other diseases might be caused by fungus which attacks the plant in the form of a mold or smut or rust. Frequently such a primary infection will weaken the plant so that a secondary infection may result from9 its lack of tolerance. The symptoms shown may cause an error in diagnosis10, so that treatment may be directed toward bacteria which could be the result of a susceptibility caused by a primary virus infection.

单选题Life Expectancy in the Last Hundred Years A hundred years ago, life expectancy in developed countries was about 47; in the early 21st century, men in the United States and the United Kingdom can expect to live to about 74, women to about 80, and these (51) are rising all the time.

Genetically, we should all be able to live to about 85 but (62) people do live longer today, there are still some big killers around that are preventing us from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those (63) by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect (64) people, but there are worrying trends in the developed world with problems such as obesity (65) more heart disease and illnesses such as diabetes at younger ages. The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.
