Five and a half years into his presidency, George Bush finally vetoed a bill this week. Oddly enough, it was one that most Americans support: it would have expanded federal funding for embryonic stem-cell research. The House and Senate had both passed the bill by wide, but not veto-proof margins, so Mr. Bush"s word is final, at least until after the mid-term elections in November. Stem cells are cells that have not yet decided what they want to be when they grow up. That is, they can become blood cells, brain cells, or pretty much any other type of cell. Their versatility makes them extremely useful for medical research. The ethical snag is that the best stem cells are harvested from human embryos, killing them. For the most ardent pro-lifers, including Mr. Bush and many of his core supporters, that is murder. Proponents of embryonic stem-cell research point out that hordes of embryos are created during fertility treatment, and the vast majority of these are either frozen indefinitely or destroyed. Is it really wrong to use them for potentially life-saving research Yes, said Mr. Bush on July 19th, flanked by some families who had "adopted" other people"s frozen embryos and used them to have children of their own. Mr. Bush"s veto does not kill stem-cell research. Scientists who spurn federal cash may do as they please. The government still pays for research on stem cells taken from adults, a process that does not kill the donor. And a decision by Mr. Bush in 2001 allows federally-funded scientists to experiment on the few dozen embryonic stem-cell "lines" that already existed then, which can be propagated in a laboratory. Nonetheless, scientists are furious with Mr. Bush. Federal funding would surely push them faster towards those elusive cures. Research based on adult stem cells may be promising, but not nearly as promising as that based on embryonic ones. There are worries that those few dozen embryonic stem-cell lines represent too narrow a gene pool, and that they cannot be endlessly extended without damaging them. Other countries, such as Britain and China, are enthusiastically experimenting on embryonic stem cells. But the world"s most innovative nation is hanging back. Scientists can go on the stem cell research because ______.

In the following text, some sentences have been removed. Choose the most suitable one from the list A—G to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the blanks. (10 points) Back in 1979, a fat, unhealthy property developer, Mel Zuckerman, and his exercise-fanatic wife, Enid, opened Canyon Ranch, "America"s first total vacation/fitness resort", on an old dude ranch in Tucson, Arizona. At the time, their outdoorsy, new age-ish venture seemed highly eccentric. Today Canyon Ranch is arguably the premium health-spa brand of choice for the super-rich. It is growing fast and now operates in several places, including the Queen Mary 2. (41)______. "There is a new market category called wellness lifestyle, and in a whole range of industries, if you are not addressing that category you are going to find it increasingly hard to stay in business", enthuses Kevin Kelly, Canyon Ranch"s president. This broad new category, Mr. Kelly goes on, "consolidates a lot of sub-categories" including spas, traditional medicine and alternative medicine, behavioural therapy, spirituality, fitness, nutrition and beauty. (42)______. "You can no longer satisfy the consumer with just fitness, just medical, just spa", says Mr. Kelly. Canyon Ranch"s strategy reflects this belief. (43)______. This year in Miami Beach it will open the first of what it expects to be many upmarket housing estates built around a spa, called Canyon Ranch Living. Together with the Cleveland Clinic, one of the world"s leading private providers of traditional medicine, it is launching an "executive health" product which combines diagnosis, treatment and, above all, prevention. It also has plans to produce food and skin-care products, a range of clothes and healthy-living educational materials. (44)______. Mr. Case reckons that one of the roots of today"s health-care crisis, especially in America, is that prevention and care are not suitably joined up. A growing number of employers now promote wellness at work, both to cut costs and to reduce stress and health-related absenteeism, says Jon Denoris of Catalyst Health, a gym business in London. He has been helping the British arm of Harley Davidson, a motorbike-maker, to develop a wellness programme for its workers. The desire to reduce health-care costs is one force behind the rise of the wellness industry; the other is the growing demand from consumers for things that make them feel healthier. Surveys find that three out of four adult Americans now feel that their lives are "out of balance", says Mr. Kelly. So there is a huge opportunity to offer them products and services that make them feel more "balanced". This represents a big change in consumer psychology, claims Mr. Kelly, and one that is likely to deepen over time: market research suggests that 35-year-olds have a much stronger desire to lead healthy lifestyles than 65-year-olds. (45)______. Another will be to maintain credibility in (and for) an industry that combines serious science with snake oil. One problem—or is it an opportunity—in selling wellness products to consumers is that some of the things they demand may be faddish or nonsensical. Easy fixes, such as new-age therapies, may appeal to them more than harder but proven ways to improve health. One of Canyon Ranch"s answers to this problem has been to hire Richard Carmona, who was America"s surgeon-general until last summer. In that role, he moved prevention and wellness nearer to the centre of public-health policy. The last time a surgeon-general ventured into business, it ended disastrously: during the internet bubble, Everett Koop launched DrKoop.com, a medical-information site that went bust shortly after going public and achieving a market capitalisation of over $1 billion. This time around, the wellness boom seems unlikely to suffer such a nasty turn for the worse.A. It is expanding a brand built on $1,000-a-night retreats for the rich and famous in several different directions.B. Mr. Zuckerman, now a trim and sprightly 78-year-old, remains chairman of the firm.C. There is growing evidence that focusing holistically on wellness can reduce health-care costs by emphasizing prevention over treatment.D. One difficulty for wellness firms will be acquiring the expertise to operate in several different areas of the market.E. It is also one of the leading lights in "wellness", an increasingly mainstream—and profitable—business.F. As more customers demand a holistic approach to feeling well, firms that have hitherto specialised in only one or two of those areas are now facing growing market pressure, to broaden their business.G. And there is much debate about the health benefits of vitamin supplements, organic food and alternative medicines, let alone different forms of spirituality.

什么是中国诗的一般印象呢提这个问题的人一定是位外国读者，或者是位能欣赏外国诗的中国读者。一个只读中国诗的人决不会提出这个问题。他能辨别，他不能这样笼统地概括。他要把每个诗人的特殊、独个的美一一分辨出来。具有文学良心和鉴别力的人像严正的科学家一样，避免泛论、概论这类高帽子、空头大话。假如一位只会欣赏本国诗的人要作概论，他至多就本国诗本身分成宗派或时期而说明彼此的特点。他不能对整个本国诗尽职，因为也没法“超以象外，得其环中”，有居高临远的观点。 本段文字意在说明______。
