  • 回答下面的题目:Easy LearningStudents should be jealous.Not only do babies get to doze their days away, but they’ve also mastered the fine art of learning in their sleep.By the time babies are a year old they can recognise a lot of sounds and even simple words.Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while they sleep as well as when they are awake.To test the theory, Cheour and her colleagues studied 45 newborn babies in the first few days of their lives.They exposed all the infants to an hour of Finnish vowel sounds—one that sounds like “oo”, another like “ee” and a third boundary vowel peculiar to Finnish and similar languages that sounds like something in between.EEG recordings of the infants brains before and after the session showed that the newborns could not distinguish the sounds.Fifteen of the babies then went back with their mothers, while the rest were split into two sleep-study groups.One group was exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to other, easier-to-distinguish vowel sounds.When tested in the morning, and again in the evening, the babies who’d heard the tricky boundary vowel all night showed brainwave activity indicating that they could now recognise this new sound.They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all.Cheour doesn’t know how babies accomplish this night-time learning, but she suspects that the special ability might indicate that unlike adults, babies don’t “turn off” their cerebral cortex while they sleep.The skill probably fades in the course of the first year of life, she adds—so forget the idea that you can pick up tricky French vowels as an adult just by slipping a language tape under your pillow.But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders.Babies can learn language even in their sleep.

  • 根据材料,回答问问题。The Science of the Future      Until recently, the "science of the future" was supposed to be electronics and artificialintelligence. Today it seems more and more likely that the next great breakthroughs intechnology will be brought through a combination of those two sciences with organic chemistryand genetic engineering. This combination is the science of biotechnology.       Organic chemistry enables us to produce marvelous synthetic (合成的) materials. However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and alsoto absorb moisture. Nothing that we have been able to produce so far comes anywhere near thecombination of strength, lightness and flexibility that we fred in the bodies of ordinary insects.Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech heartsand eyes" which can replace diseased organs in human beings. These will not be rejected by thebody, as is the case with organs from humans.       The application of biotechnology to energy production seems even more promising. In1996 the famous science-fiction writer, Arthur C. Clarke, many of whose previous predictionshave come true. He said that we may soon be able to develop remarkably cheap and renewablesources of energy. Some of these power sources will be biological. Clarke and others havewarned us repeatedly that sooner or later we wi/1 have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them alsomeans creating dangerously high levels of pollution. It will be impossible to meet the growingdemand for energy without increasing that pollution to catastrophic (灾难性的) levels unlesswe develop power sources that are both cheaper and cleaner.      It is attempting to think that biotechnology or some other "science of the future" can solveour problems. Before we surrender to that temptation we should remember nuclear power.Only a few generations ago it seemed to promise/imit/ess, cheap and safe energy. Today thosepromises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine.Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerousway.According to the passage, the science of the future is likely to be__________

  • 正确答案 :D
  • to make artificial hearts and eyes

  • 解析:【题 干】根据文章,很可能__________。 【解 析】细节题。该题无法利用题干关键词定位到原句,改为定位选项。利用选项关键词可以定位到文中第三段讲到生物化学可以帮助我们在未来生产出人工器官,以替代人体中发病的器官,所以选项D是正确答案。
