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. Biological death occurs when changes in the organism lead to the disintegration of vital cells and tissues. Death is then irreversible and final.
Scientists have been seeking a way to prolong the period of clinical death so that the organism can be reanimated before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic (麻醉的,催眠的) sleep. By slowing down the body’s metabolism, cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed and experimented on a six-year-old female baboon (狒狒) called Keta. The scientists put Keta to sleep with a narcotic. Then they surrounded her body with ice bags 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 respiration 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 respiration. After two minutes the baboon’s heart became active once more. After fifteen minutes, spontaneous respiration 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 (注射器) and ran with it around the room. Her behavior differed little from that of a healthy animal.
What’s the best title of this passage?
选项
A、The Difference between Biological and Clinical Death.
B、The Process of Dying.
C、Prolonging the Period of Clinical Death.
D、The Nature of Clinical Death.
答案
C
解析
这是一道关于文章题目的主旨题。应结合文章的主题及内容结构进行分析。文中第一段区别了死亡的两种阶段,即临床死亡和生物死亡;第二段讲述了科学家探究出的一种延长临床死亡的方法——冷冻机体;第三段举了一个冷冻狒狒的例子。从全文来看,文章的主题是关于延长临床死亡的探究。故C正确。A“生物死亡和临床死亡的区别”。这只是文中第一段所说的内容,不能作为文章的主题。B“死亡的过程”和D“临床死亡的性质”均只是文中涉及的部分内容,也不能作为文章的主题。
