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 (复活). Biological death occurs when changes in the organism lead to the disintegration (解体) 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(麻醉的) sleep. By slowing down the body’s metabolism(新陈代谢), 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. [br] According to the passage, cooling an organism______.
选项
A、speeds up the body’s metabolism
B、slows disintegration of body tissues
C、prevents damage to organs
D、revives damaged organs
答案
B
解析
可定位在第2段最后一句和第1段第4句,第2段中:By slowing down the body’smetabolism,cooling delays the processes leading to biological death(冷却能降低新陈代谢速度,从而延迟导致生物死亡的过程),而第1段则说明生物死亡表现为changes in the organism lead to thedisintegration of vital cells and tissues(有机体的变化导致活体细胞、组织纷纷解体),故正确选项为B,意为“冷却有机体能减缓身体细胞的解体”。
