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 the press, the public and many doctors convinced 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) in 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 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. 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 $ 2. 5 billion to $ 5 billion a year providing them for a relatively few dying patients. If such expenditures cut into funding for more basic care, the net effect could actually be a decline in the nation’s health.
The new models of artificial hearts are expected______.
选项
A、to have a working life of 10 or 20 years
B、to be set fully in the patient’s chest
C、to be equipped with an external power source
D、to create a new passage for infection
答案

本题是一道具体细节题。问新型人造心脏预期将会怎样。利用查阅式阅读法,我们可以在文章第二段第三句话中找到与正确答案相关的信息。这句话指出,发明者们现在正在研制新的装置,人造心脏的电源体积小,可与人造心脏一起全部植入病人的胸腔内。因此,本题的正确答案应选B“新型人造心脏预期将会被整个植入病人的胸腔内”。而其他三个选项A、C和D都与文章内容不符,都是错误的选项。
