Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two periods—clinical or temporary death and biological death. Clinical death occurs when the important organs, such as the heart or lungs, have stopped to function, but have not suffered permanent damage. The organism (有机体) can still be revived. Biological death occurs when changes in the organism lead to the “breaking up” of important cells and tissues. Death is then unchangeable.

Scientists have been seeking a way to lengthen 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, 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 scientist 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 (动脉). 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 (自发的) 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 (注射器) and ran with it around the room. It showed that Keta had nothing different from any other healthy animal.

1.For a person who suffers from the clinical death, _________.

A.he can’t avoid final death

B.he is still very much alive

C.his most important organs are damaged

D.he still has the possibility of getting back to life

2.Scientists try to make the time of clinical death longer in order to ________.

A.cool the organism

B.slow down the body’s metabolism

C.delay the coming of biological death

D.bring important cells and tissues back to active life

3.How did the scientists put Keta into clinical death?

A.By surrounding her body with ice-bags and draining her blood.

B.By lowing her blood pressure and stopping her heart from beating.

C.By putting her to sleep, lowering her temperature and draining her blood.

D.By draining her blood, lowering her blood pressure and stopping her breathing.

4.Which of the following indicates that Keta is a healthy animal after the experiment?

A.Her heart beat again.

B.She seized the syringe and ran away with it.

C.She regained her normal breath.

D.She opened her eyes and lifted her head.
