1 根据以下材料，回答题
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 ceils 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 de-lays 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 degreesthe 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 re-mained 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 scientis tstried 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.
