A
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 of 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.
56. What effect has modern technology had on medicine?
A.It has reduced the costs of medical treatment.
B.It has helped save the lives of most patients.
