He still has the possibility of getting back to life. C. He can not avoid final death. D. He is still very much alive. 【解析】選B。CDeath is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases — clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived(復活的). Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, bined with narcotic sleep. By slowing down the body’s metabolism(新陳代謝), cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a sixyearold female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with icebags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous(自發(fā)的)breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal. 【語篇概述】本文是一篇說明文。觀點態(tài)度題。故選C項。細節(jié)理解題。所以選A。推理判斷題。故選D項。代詞指代題。文章主要介紹了Mrs Larkins是如何保持健康、年輕的。BAnnette Larkins is an incredible woman who looks like a healthy 40yearold, although she just turned 70.
