“HEARTLESS”— a word you wouldn’t want to use to describe a person. But having his heart removed was what saved Craig Lewis’ life—and what made him the first living “heartless” man.
The 55-year-old，dying of heart disease，was told he only had 12 hours to live， when Billy Cohn and Bud Frazier, doctors from the Texas Heart Institute, decided to try something new. They removed Lewis heart and replaced it with an artificial (人造的) one. Less than a week after the operation, Lewis was able to sit and speak.
Lewis kept on living like a normal person, with only one difference—he didn’t have a heartbeat. The human heart usually pumps blood through our bodies by beating regularly. By contrast, this artificial heart pushes the blood forward with two moving blades(桨叶). If you were to touch Lewis or listen to his chest, you would not feel a heartbeat. If you hooked him up to an EKG(心电图) machine, the line would be flat.
Scientists have been trying to create a working artificial heart for years. Until now, all artificial hearts either broke down or caused blocks and infections.
But after five years of hard work, Dr Cohn and Dr Frazier developed this artificial heart. It is smaller and quieter than other artificial hearts and can last much longer. They tested it on 38 calves (牛犊) and all of them turned out energetic and healthy. Lewis is the first human proof that the machine is a success.
The doctors will have to work more on the device and decide on a final design before it can be widely used. The US Food and Drug Administration will also need to say that the machine is safe. But this artificial heart looks likely to bring a ray of hope to thousands of patients.

(答案→)wonder/ miracle
解析：55岁的Craig Lewis因为心脏病而被医生宣告生命仅剩下12小时，但是得克萨斯心脏研究所的人员通过移除他的心脏，用人造的心脏取而代之，结果他竟然奇迹般的幸存了下来。在本文中作者介绍了人造心脏这一科学研究成果。
【小题1】wonder/ miracle 信息归纳题。文章讲述了在死亡线上的Craig Lewis通过移植了人造心脏而幸存下来的故事，这是人类医学史上的一个奇迹，所以答案填wonder/ miracle。
【小题2】edge信息转换题。根据文章第二段 The 55-year-old，dying of heart disease，was told he only had 12 hours to live可知Craig Lewis处于死亡的边缘，填edge.
【小题3】removed 细节查找题。根据第二段They removed Lewis heart and replaced it with an artificial (人造的) one可知答案填removed.
【小题4】zero 细节转换题。根据第三段you would not feel a heartbeat，可知他是没有心跳的，所以心跳是零，填zero。
【小题5】flat细节转换题。从文章第三段 If you hooked him up to an EKG(心电图) machine, the line would be flat.可知他的心电图是平的，填flat。
【小题6】Characteristics/Features /Strengths/Advantages/Benefits细节归纳题。根据右栏的信息可知此处是介绍人工心脏的特点，性能等，所以答案是Characteristics/Features /Strengths/Advantages/Benefits。
【小题7】blocked细节转换题。根据文章第四段 Until now, all artificial hearts either broke down or caused blocks and infections.可知人工心脏没有堵塞过，所以填blocked。
【小题8】hopeful/optimistic/positive。信息归纳题。根据右栏信息可知人造心脏会给心脏病患者带来希望，所以人们有理由乐观，答案填hopeful/optimistic/positive。
【小题9】improve细节转换题。根据文章末段he doctors will have to work more on the device and decide on a final design before it can be widely used可知医生要努力去研究提高改善人造心脏的功能等，所以填improve。
【小题10】recovery /life。细节转换题。根据文章末段this artificial heart looks likely to bring a ray of hope to thousands of patients.可知人造心脏会给很多病人带来康复的机会，重新获得健康，所以答案填recovery /life。
