Modern scientists divide the process of dying into two phases — 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(復(fù)活的). Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong 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, bined with narcotic sleep. By slowing down the body’s metabolism(新陳代謝), cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a sixyearold female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with icebags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. 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(自發(fā)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 and ran with it around the room. Her behavior differed little from that of a healthy animal. 【語(yǔ)篇概述】本文是一篇說(shuō)明文。文章主要介紹了科學(xué)家們?yōu)榱搜泳徤飳W(xué)死亡期的到來(lái)、延長(zhǎng)臨床死亡的時(shí)間所做的研究。28. What can we learn from a person who suffers from the clinical death? A. His most important organs are damaged. B. He still has the possibility of getting back to life. C. He can not avoid final death. D. He is still very much alive. 【解析】選B。細(xì)節(jié)理解題。根據(jù)文章第一段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. 可知被診斷為臨床死亡的人仍有可能起死回生。所以答案選B。29. Why do scientists try to make the time of clinical death longer? A. To slow down the body’s metabolism. B. To bring vital cells and tissues back to active life. C. To cool the organism. D. To delay the ing of biological death. 【解析】選D。細(xì)節(jié)理解題。根據(jù)文章第二段的第一句中的so that the organism can remain alive before biological death occurs可知科學(xué)家們延長(zhǎng)臨床死亡的時(shí)間是為了延緩生物學(xué)死亡期的到來(lái)。所以答案選D。30. How did the scientists put Keta into clinical death? A. By putting her to sleep, lowering her temperature and draining her blood. B. By surrounding her body with icebags and draining her blood. C. By lowing her blood pressure and stopping her heart from beating. D. By draining her blood, lowering her blood pressure and stopping her breathing. 【解析】選A。細(xì)節(jié)理解題。根據(jù)文章最后一段的一些關(guān)鍵詞, 如 put Keta to sleep。 surrounded her body with icebags。 draining blood 可知詳細(xì)過(guò)程與A項(xiàng)描述一致, 故選A。31. All of the following indicate that the monkey has almost restored to her original physical state except the fact that________. A. her heart beat againB. she regained her normal breathC. she rejected a penicillin injectionD. she acted as lively as a healthy monkey【解析】選C。推理判斷題。根據(jù)文章最后一段的內(nèi)容可知, Keta的心臟恢復(fù)了跳動(dòng), 它開(kāi)始自主呼吸, 后來(lái)睜開(kāi)眼睛, 抬起頭, 這些是正常的身體狀況。它奪過(guò)注射器然后逃跑的行動(dòng)只是動(dòng)物的本能反應(yīng), 所以答案選C。DDavid Unaipon was an inventor and writer. He was the first Aboriginal(土著的) Australian to write published(出版的) books. He also worked hard to make life better for Aboriginal people. David Unaipon was born in South Australia, in 1872. As a young man, he loved to read and was interested in science and music. He thought a lot about new ways to fix engineering problems. Between the years 1909 and 1944, Unaipon made nine important inventions. He also made drawings for a helicopter(直升機(jī)) design. He got the idea from the Australian boomerang(回旋鏢) and the way it moved through the air. This happened in 1914, before we had helicopters. Unaipon lived most of his life in Adelaide and worked for the Aborigines Friends Association. He worked and travelled around southeastern Australia for fifty years. Sometimes, while travelling from town to town, he was told he couldn’t stay in a hotel b
