One way to help a patient with kidney trouble is to replace their kidneys with healthy kidneys, which is called a “transplant”. For years, scientists have tried to f

9、igure out how to transplant organs from other animals into humans.

More recently, scientists have fo

10、cused on transplants from pigs. In many ways, pigs bodies are similar to humans. Its fairly easy to raise pigs, and they grow quickly. Its now common for doctors to transplant pig heart valves (瓣膜) to repair damaged human hearts. Heart valves open and close to help the heart pump blood.But human bod

11、ies normally reject other pig organs because they contain a special chemical called “alpha-gal”. This time, to prevent the body from rejecting the pig kidney, scientists changed the pigs DNA slightly so that it wouldnt produce alpha-gal.Last month, a medical team at New York University Langone Healt

12、h, led by Dr. Robert Montgomery, attached this special pig kidney to a brain-dead human patient, who had wished to donate her organs, for the first time ever. The kidney functioned normally for the hours it was attached. “There didnt seem to be any kind of sign between the pig kidney and the human t

13、hat would make it not work,” said Montgomery. “It was beyond our expectation. It didnt have the immediate rejection that we had worried about.”Though the kidney wasnt placed inside the patients body, it was connected to the patient for over two days. During that time, the kidney worked as kidneys ar

14、e supposed to work. Most importantly, there were no signs that the kidney was being rejected. However, there are still many questions to be answered. Its not known what would happen once this kind of kidney is actually transplanted into a human. Would it be rejected after a while?5.What does paragra

20、题。在这样的情况下，纽约大学朗格尼医学中心的外科医生采取了一种惊人的做法：在征得患者家属同意后，他们将一只猪肾脏植入到一位靠呼吸机维持生命的脑死亡患者体内。而后，他们密切关注人体对移植器官的反应，同时测量这颗肾脏的功能。这是第一次有人进行此类手术。研究者仅对移植效果进行了54小时的追踪，而且对于这样一项手术的长期后果，很多问题仍有待回答。这项手术由于仍需克服在医学和监管方面的重大难题，短期内不会对患者开放。尽管如此，该领域的专家仍将这项手术誉为一个里程碑。虽然据估计，美国每年已有一亿头猪被宰杀作为食物，但要为了给人类提供器官而养猪，这种设想必然会在动物福利与剥削方面引发质疑。拓展练习阅读理解参考答案5.C 6.A 7.B 8.D学科网（北京）股份有限公司
