1.[A]文章一开头说Jarvik-7以前被认为是一大技术成就,但文章第1段倒数第2句中提到,美国食品与药品管理局得出结论,认为这种仪器与其说是挽救生命,不如说是将生命置于更加危险的境地。由此可知Jarvik-7是一个技术失败,故选A。
2.[C]文章第2段第1句提到,要求生产人造心脏的Symbion公司召回其销售的人造心脏,这对该公来说或许是一种损失,但这一禁令不会终结人们对人造心脏的需求。从这一句可推断出应选C。原文只提到政府禁止Jarvik-7这种型号的人造心脏,A把范围扩大到了所有的人造心脏;B在原文中并未提及;D说的对象不是Symbion公司,也可排除。
3.[B]文章中第2段第3句提到,这种新仪器可以完全置于患者的胸腔内,B与之相符,故选B。A在文中并未提及;C、D说的对象是Jarvik-7,故也排除。
4.[D]从句子意思看,“向为数不多的瀕危病人提供”的显然是上一句中的sampleproducts,即可与电源组一并植于人体内的newdevices,故选D。
