单选题What would you do with $590m? This is now a question for Gloria MacKenzie, an 84-year-old widow who recently emerged from hot small, tin-roofed house in Florida to collect the biggest undivided lottery jackpot in history. If she hopes her new-found fortune will yield lasting feelings of fulfillment, she could do worse than read Happy Money by Elizabeth Dunn and Michael Norton. These two academics use an array of behavioral research to show that the most rewarding ways to spend money can be counterintuitive. Fantasies of great wealth often involve visions of fancy cars and extravagant homes. Yet satisfaction with these material purchases wears off fairly quickly. What was once exciting and new becomes old hat: regret creeps in. It is far better to spend money on experience, say Ms. Dunn and Mr. Norton, like interesting trips, unique meals or even going to the cinema. These purchases often become more valuable with time—as stories or memories—particularly if they involve feeling more connected to others. This slim volume is packed with tips to help wage slaves as well as lottery winners get the most "happiness bang for your buck." It seems most people would be better off if they could shorten their commutes to work, spend more time with friends and family and less of it watching television (something the average American spends a whopping two months a year doing, and is hardly jollier for it). Buying gifts or giving to charity is often more pleasurable than purchasing things for oneself, and luxuries are most enjoyable when they are consumed sparingly. This is apparently the reason McDonald"s restricts the availability of its popular Me Rib—a marketing trick that has turned the pork sandwich into an object of obsession. Readers of Happy Money are clearly a privileged lot, anxious about fulfillment, not hunger. Money may not quite buy happiness, but people in wealthier countries are generally happier than those in poor ones. Yet the link between feeling good and spending money on others can be seen among rich and poor people around the world, and scarcity enhances the pleasure of most things for most people. Not everyone will agree with the authors" policy ideas, which range from mandating more holiday time to reducing tax incentives for American homebuyers. But most people will come away from this book believing it was money well spent.

单选题Life really should be one long journey of joy for children born with a world of wealth at their tiny feet. But psychologists now believe that silver spoons can leave a bitter taste. If suicide statistics are an indicator of happiness, then the rich are a miserable lot. Figures show that it is the wealthy who most often do away with themselves. Internationally famous child psychiatrist Dr. Robert Coles is the world"s top expert on the influence of money on children. He has written a highly acclaimed book on the subject, The Privileged Ones , and his research shows that too much money in the family can cause as many problems as too little. "Obviously there are certain advantages to being rich," says the 53-year-old psychiatrist, "such as better health education and future work prospects. But most important is the quality of family life. Money can"t buy love." It can buy a lot of other things, though, and that"s where the trouble starts. Rich kids have so much to choose from that they often become confused. Over-indulgence by their parents can make them spoilt. They tend to travel more than other children, from home to home and country to country, which causes feeling of restlessness. "But privileged children do have a better sense of their positions in the world," adds Mr. Coles, "and they axe more self-assured." I can"t imagine, for instance, that Prince William will not grow up to be self-assured. Prince William is probably the most privileged child in the world and will grow up to fill the world"s most privileged position—King of England. So money will never be one of Prince William"s problems, living anything that resembles a normal life will. "He will have a sense of isolation," cautions Dr. Coles, "and he could suffer from the handicap of not being able to deal with the everyday world because he will never really be given the chance. Royals exist in an elaborate social fantasy. Everything they have achieved is because of an accident of birth. There can be no tremendous inner satisfaction about that." Today"s wealthy parents perhaps realize their riches can be more of a burden than a blessing to their children. So their priority is to ensure that their families are as rich in love as they are in money.

单选题A city councilman has proposed a controversial new plan to increase city revenues from the parking places downtown. He has proposed that instead of charging $1.20 per hour for parking in these spots, the city should make all parking spots five-minute loading zones, and then assess $15 parking fines on anyone who parks in the spots for more than five minutes. Which of the following, if true, provides the strongest argument that the councilman's plan will not increase the city's revenue? A. A system that promotes parking fines will anger citizens, and they will consequently vote the councilman out of office if the plan goes through. B. The city owns only 14 parking spots in the downtown area. C. The costs of assessing and collecting the parking fines will surpass the revenues likely to be collected from the new plan. D. Ray's parking garage, the only competition for the city-owned parking places downtown, charges $18 per day for its parking places. E. It has been observed that on an average day, approximately three different cars park in each of the city-owned parking spots downtown.

单选题 Americans don't like to lose wars. Of course, a lot depends on how you define just what a war is. There are shooting wars—the kind that test patriotism and courage—and those are the kind at which the U.S. excels. But other struggles test those qualities too. What else was the Great Depression or the space race or the construction of the railroads? If Americans indulge in a bit of flag-waving when the job is done, they earned it. Now there is a similar challenge: global warming. The steady deterioration (恶化) of the very climate of this very planet is becoming a war of the first order, and by any measure, the U.S. is losing. Indeed, if America is fighting at all, it's fighting on the wrong side. The U.S. produces nearly a quarter of the world's greenhouse gases each year and has stubbornly made it clear that it doesn't intend to do a whole lot about it. Although 174 nations approved the admittedly flawed Kyoto accords to reduce carbon levels, the U.S. walked away from them. There are vague promises of manufacturing fuel from herbs or powering cars with hydrogen. But for a country that tightly cites patriotism as one of its core values, the U.S. is taking a pass on what might be the most patriotic struggle of all. It's hard to imagine a bigger fight than one for the survival of a country's coasts and farms, the health of its people and the stability of its economy. The rub is, if the vast majority of people increasingly agree that climate change is a global emergency, there's far less agreement on how to fix it. Industry offers its plans, which too often would fix little. Environmentalists offer theirs, which too often amount to na; ve wish lists that could weaken America's growth. But let's assume that those interested parties and others will always be at the table and will always demand that their voices be heard and that their needs be addressed. What would an aggressive, ambitious, effective plan look like—one that would leave the U.S. both environmentally safe and economically sound? Halting climate change will be far harder. One of the more conservative plans for addressing the problem calls for a reduction of 25 billion tons of carbon emissions over the next 52 years. And yet by devising a consistent strategy that mixes short-term solutions with far-sighted goals, combines government activism with private-sector enterprise and blends pragmatism (实用主义) with ambition, the U.S. can, without major damage to the economy, help halt the worst effects of climate change and ensure the survival of its way of life for future generations. Money will do some of the work, but what's needed most is will. "I'm not saying the challenge isn't almost overwhelming," says Fred Krupp. "But this is America, and America has risen to these challenges before."
