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.
From the passage we know that Symbion Inc______.
选项
A、has been banned by the government from producing artificial hearts
B、will review the effects of artificial hearts before designing new models
C、may continue to work on new models of reliable artificial hearts
D、can make new models of artificial hearts available on the market in 10 or 20 years
答案
C
解析
该题要求考生对短文进行推论。选择C项是根据短文的第二段第二、三句:One problem…chest发明家正在研究一种可以完全置于体内的人造心脏,排除了造成感染的可能性,据此可推断新样品是安全可靠的。C项符合题意。A项错误,A项的artificial hearts泛指人造心脏,而原文第一段最后一句banning the device仅指Jarvik-7一种人造心脏。D项错误,D项意为10~20年内可以制造出新型人造心脏,而原文在第二段第四句thefirst sample…20 years指出10~20年内不可能生产出新样品。
