单选题It's becoming something of a joke along the Maine-Canada border. So many busloads of retired people crisscross the line looking for affordable drugs that the roadside stands should advertise, "Lobsters. Blueberries. Lipitor. Coumalin. " Except, of course, that such a market in prescription drugs would be illegal. These senior long-distance shopping sprees fall in a legal gray zone. But as long as people cross the border with prescriptions from a physician and have them filled for no more than a three-month supply for personal use, customs and other federal officials leave them alone. The trip might be tiring, but people can save an average of 60 percent on the cost of their prescription drugs. For some, that's the difference between taking the drugs or doing without. "The last bus trip I was on six months ago had 25 seniors," says Chellie Pingree, former Maine state senator and now president of Common Cause. "Those 25 people saved $19,000 on their supplies of drugs. " Pingree sponsored Maine RX, which authorizes a discounted price on drugs for Maine residents who lack insurance coverage. The law was challenged by drug companies but recently upheld by the U. S. Supreme Court. It hasn't yet taken effect. Figuring out ways to spend less on prescription drugs has become a multifaceted national movement of consumers, largely senior citizens. The prescription drug bill in America is $160 billion annually, and people over 65 fill five times as many prescriptions as working Americans on average. "But they do it on health benefits that are half as good and on incomes that are half as large. " says Richard Evans, senior analyst at Sanford C. Bernstein, an investment research firm. What's more, seniors account for 20 percent of the voting public. It's little wonder that the May 19 Supreme Court ruling got the attention of drug manufacturers and politicians across the country. The often-over-looked state of 1.3 million tucked in the northeast corner of the country became David to the pharmaceutical industry's Goliath. The face-off began three years ago when state legislators like Pingree began questioning why Maine's elderly population had to take all those bus trips.

单选题Do you think sitting and studying all the time will improve your grades? Think again. Getting some exercise may help, too. New research with older people suggests that taking regular walks helps them pay attention better than if they didn"t exercise. Previous research had shown that mice learn, remember, and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don"t. Their brain cells also make more connections. Neuroscientists from the University at Urbana-Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked 1 mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing. Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less-fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions. In a second study, 15 elderly people who completed a 6-month aerobic-training course were faster at attention tasks compared with 14 seniors who just did stretching and toning exercises for the same amount of time. So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for your grandparents. The effects of exercising on the brains of younger people haven"t been studied yet. Still, it can"t hurt to take occasional study breaks and go for a walk or run around with your friends. You might even do better in school. Whatever you do, though, don"t try to read and walk at the same time. You could end up hurting yourself!

单选题The kids are hanging out. I pass small bands of students, in my way to work these mornings. They have become a familiar part of the summer landscape. These kids are not old enough for jobs. Nor are they rich enough for camp. They are school children without school. The calendar called the school year ran out on them a few weeks ago. Once supervised by teachers and principals, they now appear to be in "self care". Passing them is like passing through a time zone. For much of history, after all, Americans arranged the school year around the needs of work and family. In 19th-century cities, schools were open seven or eight hours a day, 11 months a year. In rural America, the year was arranged around the growing season. Now, only 3 percent of families follow the agricultural model, but nearly all schools are scheduled as if our children went home early to milk the cows and took months off to work the crops. Now, three-quarters of the mothers of school-age children work, but the calendar is written as if they were home waiting for the school bus. The six-hour day, the 180-day school year is regarded as something holy. But when parents work an eight-hour day and a 240-day year, it means something different. It means that many kids go home to empty houses. It means that, in the summer, they hang out. "We have a huge mismatch between the school calendar and the realities of family life," says Dr. Ernest Boyer, head of the Carnegie Foundation for the Advancement of Teaching." Dr. Boyer is one of many who believe that a radical revision of the school calendar is inevitable. "School, whether we like it or not, is educational. It always has been. " His is not a popular idea. Schools are routinely burdened with the job of solving all our social problems. Can they be asked to meet the needs of our work and family lives? It may be easier to promote a longer school year on its educational merits and, indeed, the educational case is compelling. Despite the complaints and studies about our kids' lack of learning, the United States still has a shorter school year than any industrial nation. In most of Europe, the school year is 220 days. In Japan, it is 240 days long. While classroom time alone doesn't produce a well-educated child, learning takes time and more learning takes more time. The long summers of forgetting take a toll. The opposition to a longer school year comes from families that want to and can provide other experiences for their children. It comes from teachers. It comes from tradition. And surely from kids. But the most important part of the conflict has been over the money.
