Most people would be impressed by the high quality of medicine available to most Americans. There is a lot of specialization, a great deal of attention to the individual, a vast amount of advanced technical equipment, and intense effort not to make mistakes because of the financial risk which doctors and hospitals must face in the courts if they handle things badly. But the Americans are in a mess. The problem is the way in which health care is organized and financed. Contrary to public belief, it is not just a free competition system. To the private system has been joined a large public system, because private care was simply not looking after the less fortunate and the elderly. But even with this huge public part of the system, which this year will eat up 84.5 billion dollars—more than 10 percent of the U.S. budget—large numbers of Americans are left out. These include about half the 11 million unemployed and those who fail to meet the strict limits on income fixed by a government trying to make savings where it can. The basic problem, however, is that there is no central control over the health system. There is no limit to what doctors and hospitals charge for their services, other than what the public is able to pay. The number of doctors has shot up and prices have climbed. When faced with toothache, a sick child, or a heart attack, all the unfortunate person concerned can do is pay up. Two-thirds of the population are covered by medical insurance. Doctors charge as much as they want knowing that the insurance company will pay the bill. The medical profession has as a result become America’s new big businessmen. The average income of doctors has now reached $100,000 a year. With such vast incomes the talk in the doctor’s surgery is as likely to be about the doctor’s latest financial deal, as about whether the minor operation he is recommending at several thousand dollars is entirely necessary. The rising cost of medicine in the U.S.A. is among the most worrying problem facing the country. In 1981 the country’s health cost climbed 15.9 percent—about twice as fast as prices in general. It is implied that American doctors often______.

There is no question that the old style of air pollution could kill people. In one week following the infamous "peasouper" fog in December 1952,4,700 people died in London. Most of these people were elderly and already had heart or lung diseases. A series of these killer fogs eventually led to the British Parliament passing the Clean Air Act which restricted the burning of coal. Fortunately the effect of smog on the lungs is not so dramatic. Scientists have now conducted a number of laboratory experiments in which volunteers are exposed to ozone inside a steel chamber for a few hours. Even at quite low concentrations there is a reversible fall in lung function, an increase in the irritability of the lungs and evidence of airway inflammation. Although irritable and inflamed lungs are particularly seen in people with asthma (哮喘) and other lung diseases, these effects of ozone also occur in healthy subjects. Similar changes are also seen after exposure to nitrogen dioxide, although there is some disagreement about the concentration at which they occur. Other studies have found that people living in areas with high levels of pollution have more symptoms and worse lung function than those living in areas with clean air. Groups of children attending school camps show falls in lung function even at quite low concentrations of ozone. There is also a relationship between ozone levels and hospital admissions for asthma, both in North America and Australia. It is suspected that long-term exposure to smog may result in chronic bronchitis (支气管炎) and emphysema (肺气肿), but this has yet to be proven. Recently an association has been found between the levels of particles in the air and death rates in North American cities. The reason for this association is not understood and as yet there is no evidence this occurs in Australia. However, we do know that hazy days are associated with more asthma attacks in children. Irritable and inflamed lungs are also seen in people with______.
