  • 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.

  • A. the scientific leadership of the U.S.
    B. the shortage of scientists in the U.S.
    C. the rapid globalization of science

  • 阅读材料,回答下面的题目。A New Strategy to Overcome Breast CancerPost-menopausal ( 绝经后 ) women who walk for an hour a day can cut their chance of breast cancer significantly,a study has suggested. The report, which followed 73,000 women for 17 years, found walking for at least seven hours a week lowered the risk of the disease. The American Cancer Society team said this was the first time reduced risk was specifically linked to walking. UK experts said it was more evidence that lifestyle influenced cancer risk. A recent poll for the charity Ramblers a quarter of adults walk for no more than an hour a week, but being active is known to reduce the risk of a number of cancers. This study, published in Cancer Epidemiology,Biomarkers&Prevention, followed 73.615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between 1992 and 1993,so it could monitor the incidence of cancer in the group. They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking, swimming and aerobics ( 有氧运动) and how much time they spent sitting watching television or reading. They completed the same questionnaires at two-year intervals between 1997 and 2009. Of the women, 47% said walking was their only recreational activity. Those who walked for at least seven hours per week had a 14% lower risk of breast cancer compared to those who walked three or fewer hours per week. Dr. Alpa Patel, a senior epidemiologist at the American Cancer Society in Atlanta, Georgia, who led the study, said: "Given that more than 60% of women report some daily walking, promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women. We were pleased to find that without any other recreational activity, just walking one hour a day was associated with a lower risk of breast cancer in these women." "More strenuous ( 紧张的) and longeractivities lowered the risk even more." Baroness Delyth Morgan, chief executive of Breast Cancer Campaign, said: "This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer and even small changes incorporate into our normal day-to-day activity can make a difference."She added: "We know that the best weapon to overcoming breast cancer is the ability to stop it occurring in the first place. The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer."All of the following factors relating to cancer risk were mentioned in the EXCEPT__________.

  • A. chief editor of Cancer Epidemiology
    B. chair of the American Cancer Society
    C. head of the survey study
    D. chief executive of Breast Cancer Campaign

  • [单选题]Compared with the etic approach, the emic approach is apparently more__________
  • 根据以下材料回答下面的题目:The Emic and Etic ApproachesResearchers who are unfamiliar with the cultural and ethnic groups they are studying must take extra precautions to shed any biases they bring with them from their own culture. For example, they must make sure they construct measures that are meaningful for each of the cultural or ethnic minority groups being studied.In conducting research on cultural and ethnic minority issues, investigators distinguish between the emic approach and the etic approach. In the emic approach, the goal is to describe behavior in one culture or ethnic group in terms that are meaningful and important to the people in that culture or ethnic group, without regard to other cultures or ethnic groups. In the eric approach, the goal is to describe behavior so that generalizations can be made across cultures. If researchers construct a questionnaire in an emic fashion, their concern is only thatthe questions are meaningful to the particular culture or ethnic group being studied. If, however, the researchers construct a questionnaire in an etic fashion, they want to include questions that reflect concepts familiar to all cultures involved.How might the emic and etic approaches be reflected in the study of family processes? In the emic approach, the researchers might choose to focus only on middle-class White families, without regard to whether the information obtained in the study can be generalized or is appropriate for ethnic minority groups. In a subsequent study, the researchers may decide to adopt an eric approach by studying not only middle-class White families, but also lower-income White families, Black American families, Spanish American families, and Asian American families. In studying ethnic minority families, the researchers would likely discover thatthe extended family is more frequently a support system in ethnic minority families than in White American families. If so, the emic approach would reveal a more different pattern of family interaction than would the etic approach, documenting that research with middle class White families cannot always be generalized to allethnic groups.According to the first paragraph, researchers unfamiliar with the target cultures are inclined to__________

  • A. culturally interactive
    B. culture-oriented
    C. culturally biased
    D. culture-specific

  • 回答下面的题目:Screen TestEvery year millions of women are screened with X-rays to pick up signs of breast cancer.If this happens early ecough, the disease can often be treated successfully.According to a survey published last year, 21 countries have screening programmes.Nine of them, including Australia, Canada, the US and Spain, screen women under 50.But the medical benefit of screening these younger women are controversial, partly because the radiation brings a small risk of inducing cancer.Also, younger women must be given higher doses of X-rays because their breast tissue is denser.Researchers at the Polytechnic University of Valencia analysed the effect of screening more than 160,000 women at 11 local clinics.After estimating the women’s cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause.The mathematical model recommended by Britain’s National Radiological Protection Board (NRPB) predicted that the screening programme would cause 36 cancers per 100,000 women, 18 of them fatal.The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led, to a lower figure of 20 cancers.The researchers argue that the level of radiation-induced cancers is “not very significant” compared to the far larger number of cancers that are discovered and treated.The Valencia programme, they say, detects between 300 and 450 cases of breast cancer in every 100,000 women screened.But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45, because they would be exposed to less radiation.The results of their study, they suggest, could help “optimise the technique” for breast cancer screening.“There is a trade-off between the diagnostic benefits of breast screening and its risks.” admits Michael Clark of the NRPB.But he warns that the study should be interpreted with caution.“On the basis of the current data, for every 10 cancers successfully detected and prevented there is a risk of causing one later in life.That’s why radiation exposure should be minimised in any screening programme.”Paragraph 2_____
