One characteristic of clinical death is__________.

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

参考答案

参考解析
解析:根据第一段“Clinical death OCCUrs when the vital organs,such as the heart or lungs,haveceased 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。

考题 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. According to the passage, cooling an organism__________. 查看材料 A.speeds up the body's metabolism B.slows disintegration of body tissues C.prevents damage to organs D.revives damaged organs

考题 One of the greatest contributions ofFreud is that he elaborated the structure of human psyche as "Id","Ego" and "Superego". "Ego" is the natural humanpsychological characteristic that changes everything in its way and makeseveryone a victim to undesirable consequences in their life. The pride andself-esteem if they are overrated in our mind will be shown in the form of Ego.The Human Ego conceals our "natural intellect" to create falseownership over every object. Here is an interesting story which couldillustrate the case. Once there was a scientist who worked hardall through his life to make exact human physical body replicas of himself. Hemastered the art so perfectly that one could not easily tell the replica fromthe original. According to the natural process, the Angel Death knocked at hisdoor. The Angel Death felt puzzled by looking at the thirteen same persons.Obviously unable to recognize the original person, the Angel returned in vain.The scientist got the illusion that he can avoid death easily. Nevertheless the Angel Death who has clearunderstanding of human life did not give up and came back with a trick Sheagain approached the scientist and was staring at the thirteen human figures. Then she told the scientist, "You havemanaged everything correctly but you could not avoid a small flaw whilereproducing yourself′. The scientist hurriedly spoke out the small flaw that itwas impossible in his work. Then he was caught by Angel Death. The Ego blinds us to hide reality, so wetend to make small mistakes though we are given greater skills and strength.Therefore each one of us has to be careful about our accomplishments andachievements so that we don′t make us blind toward this living world whereevery individual is presented upon with equal grace and strength. Thus we haveto decrease the feeling of "All is I" and increase the feeling of"I am nothing before All", which makes us proud of everything wehave. How did the Angel Death find out theoriginal of the scientist?A.By her own naked eyes. B.By finding the flaw of the scientist. C.By cheating the scientist. D.By making small mistakes.
