请阅读Passage 1,完成题:Modern scientists divide the process of dying into two stages--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 revived before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism, cooling delays the processes leading to biological death.To illustrate how this works, scientists performed an experiment on a six-year-old female monkey 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 its body. 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 its body in the direction of the heart and started artificial breathing. After two minutes the monkey's heart became active once more. After fifteen minutes, spontaneous 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.One characteristic of clinical death is__________.查看材料A.lasting damage to the lungsB.destruction of the tissuesC.temporary non-functioning of the heartD.that the organism cannot be revived
选项
A.lasting damage to the lungs
B.destruction of the tissues
C.temporary non-functioning of the heart
D.that the organism cannot be revived
答案
C
解析
根据第一段“Clinical death occurs when the vital organs,such as the heart Of lungs,have ceased to function.but have not suffered permanent damage.The organism can still be revived.”可知.临床死亡是指机体的重要器官比如心、肺等停止运转,但是还没有遭到永久的损害,机体还可以复活。因此答案为C。
