One of the greatest killers in the Western world is heart disease. The death rate (率) from the disease has been increasing at an alarming speed for the past thirty years. Today in Britain，for example，about four hundred people a day die of heart disease. Medical experts know that people can reduce their chances of getting heart disease by exercising regularly，by not smoking，by changing their diets，and by paying more attention to reducing stress(压力)in their work.

However，Western health-care systems are still not paying enough attention to the prevention of the disease. There is a need for more programs to educate the public about the causes and prevention of heart disease. Instead of supporting such programs，however，the U. S.　 health-care system is spending large sums of money on the surgical(外科的)treatment of the disease after it develops. This emphasis(强调)on treatment clearly has something to do with the technological advances that have taken place in the past ten to fifteen years. In this time，modern technology has enabled doctors to develop new surgical techniques.　 Many operations that were considered impossible or too risky(有风险的)a few years ago are now performed every day in U. S.　 hospitals. The result has been a huge increase in heart surgery.

Although there is no doubt that heart surgery can help a large number of people，some people point out that the emphasis on the surgical treatment of the disease has three clear disadvantages. First，it attracts interest and money away from the question of prevention.　 Second，it causes the costs of general hospital care to rise. After hospitals buy the expensive equipment that is necessary for modern heart surgery，they must try to recover the money they have spent. 　To do this，they raise costs for all their patients，not just those patients whose treatment requires the equipment. The third disadvantage is that doctors are encouraged to perform surgery－even on patients for whom an operation is unnecessary-because the equipment and expert skills are there. A government office recently stated that major heart surgery was often performed even though its chances of success were low. In one type of heart surgery，for example，only 15 percent of patients improved their conditions after the surgery. However，more than 100，000 of these operations are performed in the United States every year.

LONDON (Reuters)-Organic fruit, delivered right to the doorstep. That is what Gabriel Gold prefers, and he is willing to pay for it. If this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food.

　“Organic produce is always better,” Gold said. “The food is free of pesticides (农药), and you are generally supporting family farms instead of large farms. And more often than not it is locally (本地) grown and seasonal, so it is more tasty. ”Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. But how many shoppers really know what they are getting, and why are they willing to pay a higher price for organic produce? Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences-but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported (进口) to meet growing demand. “The demand for organic food is increasing by about one third every year, so it is a very fast-growing market,”said Sue Flock, a specialist in this line of business.
