　　WASHINGTON— After years working in financial and real estate management,61-year-old Bill Copeland retired to his version of the American dream-not full-time rest but a less-taxing job．

　　He's hardly alone．Close to two-thirds of Americans who have not yet retired say that when the time comes they will work for pay after retiring．The reason given most often has nothing to do with money-they simply want to stay busy．

　　For Copeland,after years of 60-and 80-hour work weeks,that means“only”40 hours a week at a job selling power tools and advising people on how to use them．

　　“I'm doing something I want to do,that I know about and I can help people,”said Copeland,who works in Falls Church,Virginia,at a Home Depot,a company that makes a special effort to attract older workers．

　　The political debate on the future of Social Security has fixed fresh attention on retirement and how older Americans make ends meet．As they live longer,healthier lives,work is a choice for an increasing number of old Americans．

　　In a recent Associated Press-Ipsos poll,63 percent of those who have not retired said they thought they would work for pay after they retired．The reason given most often was“to stay busy,”followed by“to make ends meet”and“to have enough money for extras．”

　　People find various ways to stay in the work force-working past retirement age,cutting back to part-time,or retiring and then taking a new job— often with less stress（压力）,fewer hours and less money．For many people,retirement is not an event but a process（过程）．

　　Dernnis Bardy,a 47-year-old teacher,shares the same view with many who plan to keep working．

　　“It would be nice to have a little bit of extra money,”he said,adding,“I also want to stay active．Too many times,you see people who retire just seeming to fade away．”

阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　Until last spring, Nia Parker and the other kids in her neighborhood went to school on Bus 59．But as fuel rose, the school district needed to find a way to cut its transportation costs．So the school's busing company redrew its route map, cancelling Nia's bus altogether．Now, Nia and her neighbors travel the half mile to school via a “walking school bus” － a group of kids, guarded by an adult or two, who make the walk together．

　　Like the rest of us, school districts are feeling affected by rising fuel costs－and finding new ways to adapt．The price of fuel has gone up 34 percent in the past two years．For the typical American school district, bus bills total 5 percent of the budget．As administrators look to cut down budget, busing is an inviting target, since it doesn't affect classroom instruction (or test scores)．More than one third of school administrators have cancelled bus stops or routes in order to stay within budget．

　　Many parents are delighted to see their kids walking to school, partly because many did so themselves：according to a 1969 survey, nearly half of school kids walked or biked to school, compared with only 16 percent in 2001．Modern parents have been leery of (对……存有戒心) letting kids walk to school for fear of traffic, crime or simple bullying, but with organized adult supervision(监护), those concerns have disappeared．

　　Schools and busing companies are finding other ways to save．In rural areas where busing is a must, some schools have even chosen four-day school weeks．Busing companies instruct drivers to avoid extra stops from routes and to turn off the engine while waiting．They are also using computer software to determine the most fuel-efficient routes, which aren't always the shortest ones．

　　There could be downsides, however, to the busing cutbacks．If every formerly bused student

　　begins walking to school, it's an environmental win－but if too many of their parents decide to

　　drive them instead, the overall carbon footprint can grow．Replacing buses with many more parent-driven cars can also increase safety risks：a 2002 report concluded students are 13 times safer on a school bus than in a passenger car, since buses have fewer accidents．And some students complain about the long morning hikes, particularly when the route contains a really big hill．
