He was interested in medicine from a young age. He watched his father perform operations and gained a patent (專利權(quán)) for a machine applied in the medical operation before he graduated from high school. Jarvik attended Syracuse University and considered a career in art. When his father developed heart disease suddenly, he decided then to work on a medical career. He applied to medical schools, but was not admitted to any schools in the US. Before long, he was admitted to the medical school in Italy and stayed there for two years. He returned to get a degree in medicine from New York University in 1971. After working for a period of time, Jarvik got a job in the organ transplant (器官移植) program at the University of Utah in 1972. He worked with the director of the program, Willem Kolff, who invented the kidney dialysis (腎透析) machine. By the time Jarvik came to the University of Utah, the organ program had already developed the primary artificial heart. He improved it by creating a diaphragm (膈膜), which solved many issues with the heart. Eventually, he created the first artificial heart in 1981, the Jarvik7, to be placed in a human patient, which was considered one of the most important inventions in human history. Barney Clark, a retired dentist suffering from serious heart disease, received the Jarvik7 transplant on December 2, 1982. He lived for 112 days after the operation, but the transplant was considered a success. Though receiving criticism for the risk of transplanting an artificial heart, the Jarvik7 still became very important for patients who were waiting for a heart. In 1987, Jarvik moved to New York City and formed Jarvik Research Inc. He began developing a new heart — the Jarvik 2000. This smaller machine fits inside a patient’s heart rather than replacing the entire organ. 【文章大意】本文是一篇人物傳記。詞義猜測(cè)題。故選A。根據(jù)第四段中的Eventually, he created the first artificial heart in 1981, the Jarvik7, to be placed in a human patient, which was considered one of the most important inventions in human history. 可知, 他在1981年創(chuàng)造了第一個(gè)人造心臟, 這被認(rèn)為是人類歷史上最重要的發(fā)明之一。根據(jù)第四段關(guān)鍵句“He told Reuters news agency that he got the idea for the machine when the number of cases of the COVID19 was rising quickly in the city of Wuhan. ”可知, 當(dāng)新型冠狀病毒肺炎在武漢的病例數(shù)迅速上升的時(shí)候, 鄭鋼鐵有了發(fā)明這個(gè)機(jī)器人的想法。并且根據(jù)畫線詞所在的句子“It can even disinfect itself after performing actions involving patient contact. ”可知, 它甚至能_______它自己在執(zhí)行與患者接觸的動(dòng)作后。由此可推斷出他面臨的困難是缺乏生產(chǎn)更多機(jī)器人的資金
