单选题{{B}}Text 3{{/B}} Names have gained increasing importance in the competitive world of higher education. As colleges strive for market share, they are looking for names that project the image they want or reflect the changes they hope to make. Trenton State College, for example, became the College of New Jersey nine years ago when it began raising admissions standards and appealing to students from throughout the state. "All I hear in higher education is, ' Brand, brand, brand, ' " said Tim Westerbeck, who specializes in branding and is managing director of Lipman Hearne, a marketing firm based in Chicago that works with universities and other nonprofit organizations. "There has been a sea change over the last 10 years. Marketing used to be almost a dirty word in higher education. " Not all efforts at name changes are successful, of course. In 1997, the New School for Social Research became New School University to reflect its growth into a collection of eight colleges, offering a list of majors that includes psychology, music, urban studies and management. But New Yorkers continued to call it the New School. Now, after spending an undisclosed sum on an online survey and a marketing consultant's creation of "naming structures," "brand architecture" and "identity systems," the university has come up with a new name. the New School. Beginning Monday, it will adopt new logos(标识) , banners, business cards and even new names for the individual colleges, all to include the words "the New School. " Changes in names generally reveal significant shifts in how a college wants to be perceived. In altering its name from Cal State, Hayward, to Cal State, East Bay, the university hoped to project its expanding role in two mostly suburban counties east of San Francisco. The University of Southern Colorado, a state institution, became Colorado State University at Pueblo two years ago, hoping to highlight many internal changes, including offering more graduate programs and setting higher admissions standards. Beaver College turned itself into Arcadia University in 2001 for several reasons : to break the connection with its past as a women's college, to promote its growth into a full-fledged(完全成熟的) university and, officials acknowledged, to eliminate some jokes about the college's old name on late-night television and "morning zoo" radio shows. Many college officials said changing a name and image could produce substantial results. At Arcadia, in addition to the rise in applications, the average student's test score has increased by 60 points, Juli Roebeck, an Arcadia spokeswoman, said.

Until recently most historians spoke very critically of the Industrial Revolution.

单选题Gene therapy and gene-based drugs are two ways we could benefit from our growing mastery of genetic science. But there will be others as well. Here is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the coming years. While it's true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells haven't begun to specialize. Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells--brain cells in Alzheimer's, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few. If doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue. It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations. But if efforts to understand and master stem-cell development prove successful, doctors will have a therapeutic tool of incredible power. The same applies to cloning, which is really just the other side of the coin; true cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, genetically identical to its parent. For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmot did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year. Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true "miracle cure./

单选题Most people may drink only two liters of water a day, but they consume about 3000 if the water that goes into their food is taken into account. The rich gulp down far more, since they tend to eat more meat, which takes far more water to produce than grains. So as the world's population grows and incomes rise, farmers will need a great deal more water to keep everyone fed: 2000 more cubic kilometers a year by 2030, according to the International Water Management Institute (IWMI). Yet in many farming regions, water is scarce and likely to get scarcer as global warming worsens. The world is facing not so much a food crisis as a water crisis, argues Colin Chartres, IWMI's director-general. The solution, Mr. Chartres and others contend, is more efficient use of water or, as the sloganeers put it, " more crop per drop". Some 1.2 billion people live in places that are short of water. Farming accounts for roughly 70% of human water consumption. So when water starts to run out, farming tends to offer the best potential for thrift. But governments rarely charge farmers a market price for water. So they are usually more wasteful than other consumers—even though the value they create from the water is often less than households or industry would be willing to pay for it. The pressing need is to make water go further. Antoine Frérot, the head of the water division of Veolia Environment, promotes recycling of city wastewater to be used in industry or agriculture. This costs less and cuts pollution. Yet as Mr. Fr6rot himself concedes, there are many even cheaper ways to save water. As much as 70% of water used by farmers never gets to crops, perhaps lost through leaky irrigation channels or by draining into rivers or groundwater. Investment in drip irrigation, or simply repairing the worst leaks, could bring huge savings. Farmers in poor countries can usually afford such things only if they are growing cash crops, says David Molden of IWMI. Even basic kit such as small rainwater tanks can be lacking. Ethiopia, for example, has only 38 cubic meters of storage capacity per inhabitant, compared to almost 5000 in Australia. Yet modest water storage can hugely improve yields in rain-fed agriculture, by smoothing over short dry spells. Likewise, pumping water into natural aquifers for seasonal storage tends to be much cheaper than building a big dam, and prevents the great waste of water through evaporation. Agronomists are beginning to devise tools to help monitor the efficiency of water use. Some have designed algorithms that use satellite data on surface temperatures to calculate the rate at which plants are absorbing and transpiring water. That allows governments and development agencies to concentrate their efforts on the most prodigal areas. Raising yields does not always involve greater water consumption, especially when farms are inefficient. It would take little extra water to double cereal output in many parts of Africa, Mr. Molden argues. IWMI reckons that some three-quarters of the extra food the world needs could be provided simply by bringing yields in poor countries closer to those of rich ones. That is more realistic than the absolute alternative: giving up meat and other thirsty Products altogether.

单选题Passage 3 I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today's children are significantly more anxious than children in the 1950's. In fact, the analysis showed, normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago. Why are America's kids so stressed? The report cites two main causes: increasing physical isolation--brought on by high divorce rates and less involvement in community, among other things--and a growing perception that the world is a more dangerous place. Given that we can't turn the clock back, adults can still do plenty to help the next generation cope. At the top of the list is nurturing a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress. To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep. Limit the amount of virtual violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news. Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale. Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable, but it doesn't have to ruin your life.
