单选题 States are considering major changes in prepaid college tuition programs—raising prices, restricting participation or canceling them—as they grapple with financial woos.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 Dee. 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 bear 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 bail out. 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 〈SavingforCollege. 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-in-come 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$8000, more than 400% 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 press mocked his attempts to appeal to young voters.

单选题Greg Gadson, a lieutenant colonel in the Army's Warrior Transition Brigade, is a natural leader—the kind of guy you'd be looking for on the battlefield. He's also the kind of guy Mike Sullivan, a coach for the New York Giants, whose thought could make a difference to his losing football team. The two men had gone to US Military Academy at West Point together but hadn't been in touch much afterward, until Sullivan walked into Gadson's hospital room at Walter Reed Army Medical Center, outside Washington, D.C., last June. Friends had told Sullivan that his former Army football teammate had suffered serious injuries in Iraq—resulting in both of Gadson's legs being amputated above the knee. "This man had suffered so much," Sullivan recalls, "yet he was so happy to see me." The coach, who brought his old friend a signed Giants jersey with the number 98 on it, watched as Gadson interacted with the other patients and the doctors and nurses, encouraging them all. "To see the impact he had on these people—the look in his eyes and how they responded—was overwhelming and inspirational." Sullivan couldn't help but be impressed by Gadson's enthusiasm and lack of self-pity. When the Giants were scheduled to play the Redskins in Washington three months later, Sullivan sent his friend tickets—along with a request: Would Gadson speak to the team before they took the field? Having lost the first two games of the season, the Giants had already given up 80 points and, worse, seemed to be playing with no heart. The coach felt that Gadson was the perfect person to tell the players something they needed to hear about commitment, about perseverance, about teamwork. Teamwork was everything to Gadson. He had played football at Indian River High School in the Tidewater region of Virginia and gone on to become a starting linebacker—No. 98 for West Point from 1986 to 1988, despite his relatively slight build of 190 pounds on a 5-foot-11 frame. Following his graduation, Gadson, the son of a hospital pharmacist and a teacher, planned to serve his compulsory five years and get out. But after tours in the Balkans and Afghanistan, he found himself hooked. "Serving my country is important," he says, "but for me it's about being a soldier, being there for each other in the biggest sense of the word. I love being part of that team./

单选题 How men first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sound to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words. The power of words, then, lies in their associations-the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and dull.

单选题{{B}}Passage 3{{/B}} Psychologist George Spilich and colleagues at Washington College in Chestertown, Maryland, decided to find out Whether, as many smokers say, smoking helps them to "think and concentrate." Spilich put young non-smokers, active smokers and smokers deprived (被剥夺) of cigarettes through a series of tests. In the first test, each subject (试验对象) sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96. In this simple test, smokers, deprived smokers and nonsmokers performed equally well. The next test was more complex, requiring all to scan sequences of 20 identical letters and respond the instant one of the letters was transformed into a different one. Non-smokers were faster, but under the stimulation of nicotine (尼古丁), active smokers were faster than deprived smokers. In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers. The fourth test required people to read a passage, then answer questions about it. Non-smokers remembered 19 percent more of the most important information than active smokers, and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also had trouble separating important information from insignificant details. "As our tests became more complex," sums up Spilich, "non-smokers performed better than smokers by wider and wider margins." He predicts, "smokers might perform adequately at many jobs until they got complicated. A smoking airline pilot could fly adequately if no problems arose, but if something went wrong, smoking might damage his mental capacity."
