阅读材料，回答下面的题目。The Diminishing Scientific Leadership of the U, S.With the rapid globalization of science itself ( more than 40 percent of scientific Ph.D. students trained in the United States are now foreign nationals, roughly half of whom return to their countries of origin ) , the once undisputed U.S.scientific lead, whether relevant to product lead or not, is diminishing. The competition of foreign students for positions in U.S.graduate schools has also contributed to making scientific training relatively unattractive to U.S.students, because the rapidly increasing supply of students has diminished the relative rewards of this career path. For the best and brightest from low-income countries, a position as a research assistant in the United States is attractive, whereas the best and brightest U.S.students might now see better options in other fields. Science and engineering careers, to the extent that they are opening up to foreign competition ( whether imported or available through better communication ) , also seem to be becoming relatively less attractive to U.S. students. With respect to the role of universities in the innovation process the speculative boom of the 1990s( which, among other things, made it possible to convert scientific findings into cash rather quickly ) was largely unexpected.The boom brought universities and their faculties into much closer contact with private markets as they tried to gain as much of the economic dividends from their discoveries as possible. For a while,the path between discoveries in basic science and new flows of hard cash was considerably shortened. But during the next few decades, this path will likely revert toward its more traditional length and reestablish in a healthy way, the more traditional ( and more independent ) relationship between the basic research done at universities and those entities that translate ideas into products and services.In the intervening years, another new force also greatly facilitated globalization: the rapid growth of the Internet and cheap wide-bandwidth international communication. Today, complex design activities can take place in locations quite removed from manufacturing, other business functions and the consumer. Indeed, there is now ample opportunity for real-time communication between business functions that are quite independent of their specific locations. For example, software are development, with all its changes and complications, can to a considerable extent be done overseas for a U.S.customer.Foreign call centers can respond instantly to questions from thousands of miles away.The result is that low-wage workers in the Far East and in some other countries are coming into even more direct competition with a much wider spectrum of U.S. labor: unskilled in the case of call centers; more highly skilled in the case of programmers.

the boom of the l990s could be considered somewhat unhealthy

解析：【答案】C【解析】根据第三段最后一句中的“But during the next few decades，this path likely will…reestablish，in a healthy way，the traditional relationship…”可知，作者本文隐含的意思是，“the boom ofthe 1990s was not healthy”。

回答下面的题目：UndergrOund Coal Fires Coal burning deep underground in China, India and Indonesia is threatening the environment and human life, scientists have warned. These large scale 51 blazes ( 火焰 ) cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can 52 ignite ( 点燃) forest fires, a group of scientists told the annual meeting of the American Association for the Advancement of Science in Denver. The resulting 53 of poisonous elements like mercury can also pollute local water sources and soils, they warned."Coal fires are a global disaster," said Associate Professor Glenn Stracher of East Georgia Collage in Swainsboro, USA. But 54 few people know about them.Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not caused to 55 and under the right combinations of sunlight and oxygen, can trigger spontaneous ( 自发的 ) catching fire and burning. This can occur underground, in coal stockpiles, abandoned mines or even as coal is transported. 56 fires in China consume up to 200 million tons of coal per year, delegates were told. In 57 , the U.S. economy consumes about one billion tons of coal annually, said Stracher, 58 analysis of the likely impact of coal fires has been accepted for publication in the International Joomal of Acoal Ecology.. 59 underway, coal fires can burn for decades, even centuries. In the process, they release large 60 of greenhouse gases, poisonous fumes and black particles into the atmosphere.The members of the panel discussed the 61 these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to 62Ultimately, the remote sensing and other techniques should allow scientists to 63 how much carbon dioxide these fires are emitting ( 释放 ). One suggested 64 of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed a heat-resistant grout ( 灌浆 ), which is designed to be pumped into the coal fire to 65 the oxygen supply.第51题应选：

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.
