Passage 1 States are considering major changes in prepaid college tuition programs - raising prices, restricting participation of canceling them - as they grapple with financial woes. Nationwide, families will likely have to pay more to participate, or accept that they might not cover tuition when children go to college. Colorado has closed its prepaid plan to new investors and told existing ones that it may not cover future tuition increases. Wisconsin stopped selling its plan Dec. 20. Maryland and Illinois are among states hiking prices by 20% or more. Prepaid plans let parents lock in tuition by paying for it now, protecting them against rising costs. But the hear market has hurt investment returns, leaving the plans unable to keep up with big increases in tuition. So far, Colorado is the only state that has told participants their investments may not cover tuition, and no plan has missed a payment. Other states have said they will fulfill obligations, even if it requires a legislative bailout. Still, the financial problems have forced thousands to grapple with uncertainty - something prepaid plans were designed to avoid. More than 1 million families have an estimated $ 8 billion invested in the plans, says ＜ Saving for College. com ＞. Some states, including Colorado, may replace the prepaid plan with a guaranteed investment contract, a CD-like investment that's backed by an insurance company. Investors get a minimum rate of return, but no guarantee that it will cover tuition. Wisconsin's EdVest program is encouraging investment in a stable value fund, which is similar to a guaranteed investment contract, in its investment plan. Wisconsin's prepaid plan never guaranteed to cover tuition inflation. It also never got a lot of investors, possibly because it lacked that guarantee. In Florida, a task force is considering limiting the state's prepaid program to low-income families. Ohio officials are also looking at limiting participation, but it's a measure they hope to avoid. "Program administrators are looking for alternatives," says Andrea Feirstein, a state-plan consultant. Maryland recently boosted its prices by up to 30%; Illinois by up to 23%. The increases have made some prepaid plans uneconomical for parents of older children. In Ohio, the price of one year's tuition for a child over 12 months old is $ 8, 000, more than 40% above current tuition at Ohio State. SO it may not be a good deal for children starting college in three or four years because tuition may not jump that much that fast.

单选题The two claws of the mature American lobster are decidedly different from each other. The crusher claw is short and stout; the cutter claw is long and slender. Such bilateral asymmetry, in which the right side of the body is, in all other respects, a mirror image of the left side, is not unlike handedness in humans. But where the majority of humans are right-handed, in lobsters the crusher claw appears with equal probability on either the right side or left side of the body. Bilateral asymmetry of the claws comes about gradually. In the juvenile fourth and fifth stages of development, the paired claws are symmetrical and cutterlike. Asymmetry begins to appear in the juvenile sixth stage of development, and the paired claws further diverge toward well-defined cutter and crusher claws during succeeding stages. An intriguing aspect of this development was discovered by Victor Emmel. He found that if one of the paired claws is removed during the fourth or fifth stage, the intact claw invariably becomes a crusher, while the regenerated claw becomes a cutter. Removal of a claw during a later juvenile stage or during adulthood, when asymmetry is present, does not alter the asymmetry; the intact and regenerate claws retain their original structures. These observations indicate that the conditions that trigger differentiation must operate in a random manner when the paired claws are intact but in a nonrandom manner when one of the claws is lost. One possible explanation is that differential use of the claws determines their asymmetry. Perhaps the claw that is used more becomes the crusher. This would explain why, when one of the claws is missing during the fourth or fifth stage, the intact claw always becomes a crusher. With two intact claws, initial use of one claw might prompt the animal to use it more than the other throughout the juvenile fourth and fifth stages, causing it to become a crusher. To test this hypothesis, researchers raised lobsters in the juvenile fourth and fifth stages of development in a laboratory environment in which the lobsters could manipulate oyster chips. (Not coincidentally, at this stage of development lobsters typically change from a habitat where they drift passively, to the ocean floor where they have the opportunity to be more active by borrowing in the substrate.) Under these conditions, the lobsters developed asymmetric claws, half with cutter claws on the left, and half with crusher claws on the right. In contrast, when juvenile lobsters were reared in a smooth tank without the oyster chips, the majority developed two cutter claws. This unusual configuration of symmetrical cutter claws did not change when the lobsters were subsequently placed in a manipulatable environment or when they lost and regenerated one or both claws.

单选题Passages 4 As a wise man once said, we are all ultimately alone. But an increasing number of Europeans are choosing to be so at an ever earlier age. This isn't the stuff of gloomy philosophical contemplations, but a fact of Europe's new economic landscape, embraced by sociologists, real-estate developers and ad executives alike. The shift away from family life to solo lifestyle, observes a French sociologist, is part of the "irresistible momentum of individualism" over the last century. The communications revolution, the shift from a business culture of stability to one of mobility and the mass entry of women into the workforce have greatly wreaked havoc on (扰乱) Europeans' private lives. Europe's new economic climate has largely fostered the trend toward independence. The current generation of home-aloners came of age during Europe's shift from social democracy to the sharper, more individualistic climate of American style capitalism. Raised in an era ofprivatization and increased consumer choice, today's tech-savvy (精通技术) workers have embraced a free market in love as well as economics. Modem Europeans are rich enough to afford to live alone, and temperamentally independent enough to want to do so. Once upon a time, people who lived alone tended to be those on either side of marriage--twenty something professionals or widowed senior citizens. While pensioners, particularly elderly women, make up a large proportion of those living alone, the newest crop of singles are high earners in their 30s and 40s who increasingly view living alone as a lifestyle choice. Living alone was conceived to be negative--dark and cold, while being together suggested warmth and light. But then came along the idea of singles. They were young, beautiful, and strong! Now, young people want to live alone. The booming economy means people are working harder than ever. And that doesn't leave much room for relationships. Pimpi Arroyo, a 35-year-old composer who lives alone in a house in Paris, says he hasn't got time to get lonely because he has too much work. "I have deadlines which would make life with someone else fairly difficult." Only an Ideal Woman would make him change his lifestyle, he says Kaufmann, author of a recent book called "The Single Woman and Prince Charming", thinks this fierce new individualism means that people expect more and more of mates, so relationships don't last long-- if they start at all. Eppendorf, a blond Berliner with a deep tan, teaches grade school in the mornings. In the afternoon she sunbathes or sleeps, resting up for going dancing. Just shy of 50, she says she'd never have wanted to do what her mother did--give up a career to raise a family. Instead, "I've always done what I wanted to do: live a self-determined life./
