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 mode is that the tubes connecting it to an external power source createda passage for infection. Inventors are now working on new devices that would be fully placed, along with atiny 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 (開(kāi)支) cut into funding for more basic care, the net effect could actually be a decline in the nation’s health.

參考答案
1.[A] 文章一開(kāi)頭說(shuō)Jarvik-7以前被認(rèn)為是一大技術(shù)成就，但文章第1段倒數(shù)第2句中提到,美國(guó)食品與藥品管理局得出結(jié)論,認(rèn)為這種儀器與其說(shuō)是挽救生命,不如說(shuō)是將生命置于更加危險(xiǎn)的'境地。由此可知Jarvik-7是一個(gè)技術(shù)失敗,故選A。
2.[C] 文章第2段第1句提到，要求生產(chǎn)人造心臟的Symbion公司召回其銷售的人造心臟，這對(duì)該公來(lái)說(shuō)或許是一種損失，但這一禁令不會(huì)終結(jié)人們對(duì)人造心臟的需求。從這一句可推斷出應(yīng)選C。原文只提到政府禁止Jarvik-7這種型號(hào)的人造心臟，A把范圍擴(kuò)大到了所有的人造心臟;B在原文中并未提及;D說(shuō)的對(duì)象不是Symbion公司，也可排除。
3.[B] 文章中第2段第3句提到，這種新儀器可以完全置于患者的胸腔內(nèi)，B與之相符，故選B。A在文中并未提及;C、D說(shuō)的對(duì)象是Jarvik-7，故也排除。
4.[D] 從句子意思看，“向?yàn)閿?shù)不多的瀕危病人提供” 的顯然是上一句中的sample products，即可與電源組一并植于人體內(nèi)的new devices，故選D。
5.[B] 第2段倒數(shù)第2句But some people are already worrying…這句話體現(xiàn)了有些人已經(jīng)在擔(dān)心，為為數(shù)不多的垂危病人動(dòng)用巨額資金購(gòu)置新型的人造心臟是否合算，而由該段最后一句可以看出作者認(rèn)為這樣的做法是不明智的，因此B是答案。
