六级阅读技巧：怎样回答细节性问题

　　A) a technical failure

　　B) a technical wonder

　　C) a good life-saver

　　D) an effective means to treat heart disease

　　本题是考核学生根据止下文全面理解和进行正确判断的能力，问的是本文论述的Jarvik-7人造心脏性能和效果到底如何。文章一开头说Jarvik-7是一大技术成就，但文章说到：…the .U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them (Line -7-9).后面又提到：Last week the agency canceled its earlier approval , effectively banning the device.这两句话提供了这个问题的答案。因此，答案：

The new models of artificial hearts are expected_______.

　　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

　　本题是考核正确理解事实细节的能力。选项已的意思与文章中第二段第三句，即"Inventors are now working…in the patient’s chest."的意思符合，因此选项B)是答案。
