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”。

阅读材料，回答下面的题目： What We Take from and Give to the Sea  As long as we have been on earth, we have used the sea around us. We take from the ocean, and we give to it. We take fishes from the ocean-millions of kilograms of fish, every year, to51millions of people. We even52their bones for fertilizer. We take minerals from the ocean. One way to get salt is to53seawater in shallow basin and leave until it evaporates( 蒸发 ). Along with salt, other minerals are left 54 evaporation.Much gold and silver drift dissolved in the waters of the sea, too. But the sea does not give them 55 by simpleevaporation.56gifts from the sea are pearls, sponges( 海绵) and seaweed. Pearls57jewelry. Natural sponges become cleaning aids. Seaweed becomes 58 of many kinds-even candy, and ice cream - as well as medicine. Believe it or not, fresh water is another 59 from the sea. We cannot drink ocean water. Some of its contents may. 60 illness. But ocean water becomes fresh water when the salts are 61 . In the future, we will find ourselves 62 more and more on fresh water from the sea. The sea63us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. We pollute the ocean 64 we use it as a garbage dump. Huge as it is, the ocean cannot hold all the water that we pour into it. 65 garbage into the ocean is killing off sea life.

[单选题]回答{TSE}题:Exercise Being Good or BadCan exercise be a bad thing? Sudden death during or soon after strenuous exertion on the squash court or on the army training grounds, is not unheard of. 51 trained marathon runners are not immune to fatal heart attacks. But no one knows just 52 common these sudden deaths linked to exercise are. The registration andinvestigation of such 53 is very patchy; only a national survey could determine the true 54 of sudden deaths in sports. But the climate of medical opinion is shifting in 55 of exercise, for the person recovering from a heart attack as 56 as the average lazy individual. Training can help the victim of a heart attack bylowering the 57 of oxygen the heart needs at any given level of work 58 the patient can do more before reaching the point where chest pains indicate a heart starved of oxygen. The question is, should middle-aged people, 59 .particular, be screened for signs of heart disease before 60 vigorous exercise?Most cases of sudden death in sport are caused by lethal arrhythmias in the beating of the heart, often in people 61 undiagnosed coronary heart disease. In North America 62 over 35 is advised to have a physical check-up and even an exercise electrocardiogram. The British, on the whole, think all this testing isunnecessary. Not many people die from exercise, 63 , and ECGs ( 心电图 ) are notoriously inaccurate. However, two medical cardiologists at the Victoria Infirmary in Glasgow, advocate screening by exercise ECG for people over 40, or younger people 64 at risk of developing coronary heart disease. Individuals showing a particular abnormality in their ECGs 65 , they say, a 10 to 20 times greater risk of subsequently developing signs of coronary heart disease, or of sudden death.{TS}第51题应选：

[单选题]The three vowels mentioned in this article are all Finnish sounds.

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.

根据以下资料，回答下面的题目。 请在第_____处填上正确答案。

cost   

解析：at the moment接of，意为“在……时刻”；risk一般也与0f搭配，at risk of意为“冒……的风险”；at speed of意为“……的速度”。只有A项cost能与for搭配，at the cost for意为“以……为代价”，此句意思是城市密集的建设模式和选址常常以居民面临自然灾害为代价。所以本题选A。
