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 scientific leadership of the U．S．

解析：【答案】A【解析】第一段开头即点明了文章主旨：“the once，undisputed U．S．scientific lead…is diminishing．”。其他三段从三个方面对此作了阐述：“scientific training relatively unattractive to U．S．students”，“during the next few decades，this path likely will revert toward its more traditional length and reestablish， in a healthy way，the more traditional relationship…”，“another new force also greatly facilitated globalization”。由此可知，本文着重讨论的是科学全球化造成美国科技领先地位的下降。主旨归纳题，应明确文章的中心思想。

[单选题]根据以下材料回答{TSE}题：Benefited or HurtFor the most part, it seems, workers in rich countries have little to fear from globalization, and a lot to gain. But is the same thing true for workers in poor countries? The answer is that they are even more likely than their rich country counterparts to benefit, because they have less to lose and more to gain. Orthodox economics takes an optimistic line on integration and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labor have already been used up. If pool countries lower their barriers to trade and investment, the theory goes: rich foreigners wilt want to send over some of their capital.If this inflow of resources arrives in the form of loans or portfolio investment, it will supplement domestic savings and loosen the financial constraint on additional investment by local companies. If it arrives in the form of new foreign controlled operations, FDI, so much the better: this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investmentought to push incomes up, partly by raising the demand for labor and partly by making labor more productive. This why workers in FDI receiving countries should be in an even better position to profit from integration than workers in FDI sending countries. Also, with or without inflows of foreign capital, the same static and dynamic gains from trade should apply in developing countries as in rich ones. This gain from trade logic often arouses suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets though trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory, trade is a positive sum game. In all these transactions, sides exporters and importers, borrowers and lenders, shareholders and workers can gain.{TS}According to the passage, who may be reasonably afraid of the globalization?

None of them

解析：【解析】文章第一段中说明，“workers in rich countries have little to fear from globalization”和“they are ever more likely than their rich country counter parts to benefit”，可知穷国和富国的工人都会在全球化中得到很大的好处，因此都不必害怕全球化，D为正确选项。

[单选题]Finnish vowels are easy to distinguish.

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.
