单选题Watch a baby between six and nine months old, and you will observe the basic concepts of geometry being learned. Once the baby has mastered the idea that space is three-dimensional, it reaches out and begins grasping various kinds of objects. It is then, from perhaps nine to fifteen months, that the concepts of sets and numbers are formed. So far, so good. But now an ominous development takes place. The nerve fibers in the brain insulate themselves in such a way that the baby begins to hear sounds very precisely. Soon it picks up language, and it is then brought into direct communication with adults. From this point on, it is usually downhill all the way for mathematics, because the child now becomes exposed to all the nonsense words and beliefs of the community into which it has been so unfortunate as to have been born. Nature, having done very well by the child to this point, having permitted it the luxury of thinking for itself for eighteen months, now abandons it to the arbitrary conventions and beliefs of society. But at least the child knows something of geometry and numbers, and it will always retain some memory of the early halcyon days, no matter what vicissitudes it may suffer later on. The main reservoir of mathematical talent in any society is thus possessed by children who are about two years old, children who have just learned to speak fluently.

单选题Drunken driving- sometimes called America's socially accepted form of murder- has become a national epidemic (流行病) . Every hour of every day about three Americans on average are killed by drunken drivers. A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American man image and judges were tolerant in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers more than doubled, so the state recently upped it back to 21. Reformers, however, fear raising the drinking age will have little effect unless accomplished by educational programs to help young people to develop "responsible attitudes" about drinking and teach them to resist pressure to drink. Tough new laws have led to increased arrests and tests and, in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks. A tavern (酒店主) in Massachusetts was fined for serving six or more double brandies to a customer who was "obviously intoxicated" and later drove off the road, killing a nine-year-old boy. As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition of alcohol that began in 1919. They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.

单选题{{B}}Text 2{{/B}} To forgive may be divine, but no one ever said it was easy. When someone has deeply hurt you, it can be extremely difficult to let go of your grudge. But forgiveness is possible—and it can be surprisingly beneficial to your physical and mental health. "People who forgive show less depression, anger and stress, and more hopefulness," says Frederic Luskin, Ph. D., author of Forgive for Good (HarperCollins, 2002). "So it can help save on the wear and tear on our organs, reduce the wearing out of the immune system and allow people to feel more vital." So how do you start the healing? Try following these steps: Calm yourself. To defuse your anger, try a simple stress-management technique. "Take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, someone you love, "Luskin says. Don't wait for an apology. "Many times the person who hurt you has no intention of apologizing," Luskin says. "They may have wanted to hurt you or they just don't see things the same way. So if you wait for people to apologize, you could be waiting an awfully long time." Keep in mind that forgiveness does not necessarily mean reconciliation with the person who upset you or condoning of his or her action. Take the control away from your offender. Mentally replaying your hurt gives power to the person who caused you pain. "Instead of focusing or, your wounded feelings, learn to look for the love, beauty and kindness around you," Luskin says. Try to see things from the other person's perspective. If you empathize with that person, you may realize that he or she was acting out of ignorance, fear—even love. To gain perspective, you may want to write a letter to yourself from your offender's point of view. Recognize the benefits Of forgiveness, Research has shown that people who forgive report more energy, better appetite and better sleep patterns. Don't forget to forgive yourself. "For people, forgiving themselves is the biggest challenge, "Luskin says. "But it can rob you of your self-confidence if you don't."
