Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark-alive and conscious after trading his diseased heart for a metal-and-plastic pump-convinced the press, the public and many doctors that the future had arrived. It hadn’t After monitoring production of the Jarvik-7,and reviewing its effects on the 150 or so patients(most of whom got the device as a temporary measure) the U. S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them Last week the agency cancelled its earlier approval, effectively banning (禁止) the device.
The recall may hurt Symbion Inc, maker of the Jarvik-7, but it won’t end the request for an artificial heart. One problem with the banned model is that the tubes connecting it to an external power source created a passage for infection(感染). Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient’s chest. The first sample products aren’t expected for another 10 or 20 years. But some people are already worrying that they’ll work—and that America’s overextended health-care programs will lose a precious $ 5 billion a year providing them for a relatively few dying patients. If such expenditures(开支) cut into funding for more basic care, the net (最终的) effect could actually be a decline in the nation’s health.
According to the passage the Jarvik-7 artificial heart proved to be______.
选项
A、a good life-saver
B、a technical wonder
C、a technical failure
D、an effective means to treat heart disease
答案
C
解析
根据第一段第四句:the U.S.Food and Drug Administration coneluded that the machine was doing more to endanger lives than to save them.问题项里的“prove”一词与原文的"concluded”一词相近。两个词都强调调查的结果/结论,因而排除B项a technical wonder作为答案的可能性,而确定C项正确。
