单选题I lost my sight when I was four years old by falling off a box car in a freight yard in Atlantic City and landing on my head. Now I am thirty-two. I can vaguely remember the brightness of sunshine and what color red is. It would be wonderful to see again, but a disaster can do strange things to people. It occurred to me the other day that I might not have come to love life as I do if I hadn't been blind. I believe in life now. I am not so sure that I would have believed in it so deeply, otherwise. I don't mean that I would prefer to go without my eyes. I simply mean that the loss of them made me appreciate the more what I had left. Life, I believe, asks a continuous series of adjustments to reality. The more readily a person is able to make these adjustments, the more meaningful his own private world becomes. The adjustment is never easy. I felt helpless and afraid. But I was lucky. My parents and my teachers saw something in me--a potential to live, you might call it--which I didn't see, and they made me want to fight it out with blindness. The hardest lesson I had to learn was to believe in myself. That was basic, If I hadn't been able to do that, I would have collapsed and become a chair rocker on the front perch for the rest of my life. When I say belief in myself I am not talking about simply the kind of self-confidence that helps me down an unfamiliar staircase alone. That is part of it. But I mean something bigger than that: an assurance that I am, despite imperfections, a real, positive person; that somewhere in the sweeping, intricate pattern of people there is a special place where I can make myself fit. It took me years to discover and strengthen this assurance. It had to start with the most elementary things. Once a man gave me an indoor baseball. I thought he was making fun of me and I was hurt. "I can't use this," I said. "Take it with you," he urged me, "and roll it around." The words stuck in my head. "Roll it around!" By rolling the ball I could hear where it went. This gave me an idea how to achieve a goal I had thought impossible: playing baseball. At Philadelphia's Overbrook School for the Blind I invented a successful variation of baseball. We called it ground ball. All my life I have set ahead of me a series of goals and then tried to reach them, one at a time. I had to learn my limitations. It was no good to try for something I knew at the start was wildly out of reach because that only invited the bitterness of failure. I would fail sometimes anyway but on average I made progress.

单选题It is generally believed that the greatest damage of old age is the loss of mental faculties. With the near doubling of life expectancy in the past century has come a mixed blessing. A few great thinkers and artists remained productive in their later years—Galileo, Monet, Shaw, Stravinsky, Tolstoy—but even they were not what they bad been in their primes. In sciences, the boom falls sooner still: "A person who has not made his great contribution to science before the age of 30 will never do so," said Einstein. Imagine if we could transplant old brains into younger bodies: would our minds stay young, or would we be senile teenagers, scaling mountains and skateboarding at 120, but forgetting where we put the car's keys. Is the brain uniquely vulnerable to the ravages of time? Can anything be done? Indisputable evidence from many studies shows that a higher level of education and greater mental activity throughout life correlated with lower cognitive losses in old age. These benefits apply to all sons of cognitive losses, including those associated with dementia. Some researchers believe that mental application in early life produces complex neural connections that provide a reserve later on; others argue that education merely gives people the means to cope with and compensate for their losses. K. Warner Shay, a professor of human development and psychology at Pennsylvania State University, has studied age-related change in more than 5,000 people, some for more than 40 years. Comparing earlier with later recruits, Mr. Shay concludes that the rate of mental decline is slowing, a change he attributes to better education, healthier diet, lessened exposure to serious disease, and more mental activity. "You've got to practise," Mr. Shay says. "If you don't solve problems, you no longer can solve problems." Retirement can be particularly hard, he adds, because for many people, work is their most challenging activity. "Retirement is good for people who've had routine jobs—they may find something more stimulating. But it's disadvantageous for people in high-level jobs, who are less likely to find something as stimulating as the job they had." K. Anders Ericsson, a psychology professor at Florida State University, confirms Mr. Shay's emphasis on the virtue of practice. Initially interested in expert performance like musicians, he found that many geniuses aren't really so different from everyone else—they just practise harder and longer, benefiting from sheer labor, rather than from some special gift. Professional musicians who continue to practise assiduously as they age continue to play well, while amateurs who just play for pleasure show age-related declines. Mr. Ericsson's studies failed to show significant generalized fitness from mental exercise. If you play tennis, you improve your general fitness, but the greatest improvement is specific to tennis, not to other sports. It's the same with cognitive exercise. You have to look at your life and pick what you want to improve.

单选题 Rich Americans are willing to take conspicuous consumption to new heights by spending big bucks to fly into space, including paying 100,000 for a 15-minute trip into the heavens, according to a poll released on Monday. Possibly bored by the banal baubles of mundane Mother Earth or inspired by the dashing derring-do of such pioneers as first American in space Alan Shepard and first millionaire in space Dennis Tito, the poll says 7 percent of rich Americans would pay 20 million for a two-week orbital-flight and 19 percent would pay 100,000 for 15-minute sub-orbital flight. The poll by Zogby International was commissioned by Futron Corp., a Maryland aerospace consulting group which has a 1.8 million contract with NASA to explore the commercial applications of space travel, including what space tourism could look like in the next 20 years. Zogby International conducted telephone interviews with 450 Americans whose yearly incomes exceed 250,000 or whose net worth exceeds 1 million. The polls, conducted in January but only released Monday, has a margin of error of plus or minus 4.7 percent. Futron's NASA project program manager Derek Webber said, "We commissioned this survey in order to get an idea of what rich people think and not the man in the street who loves the idea of going into space but can't afford it." He added, "We are saying these trips will cost a minimum of 100,000 for a 15-minute trip, which was the amount of time the first American in space, Alan Shepard, had and for that you get to feel space weightlessness and see the world from up there." That trip would take a tourist 50 miles (80 km) into space. Webber said a surprising 7 percent of the wealthy polled said they would be willing to take a two-week flight to an orbiting space station, paying the 20 million that the Russians charged the two pioneering space tourists who have already made the trip, South African Mark Shuttleworth and American Dennis Tito. If the price dropped to $50,000, 16 percent of those surveyed would be interested. Space tourists would have to meet medical standards and only be able to go to the International Space Station. N'Sync singer Lance Bass is currently undergoing tests to see if he could become the third space tourist. He wants to become the first entertainer in space.
