单选题"It is an evil influence on the youth of our country. " A politician condemning video gaming? Actually, a clergyman denouncing rock and roll 50 years ago. But the sentiment could just as easily have been voiced by Hillary Clinton in the past few weeks, as she blamed video games for "a silent epidemic of media desensitisation" and "stealing the innocence of our children". The gaming furore centers on "Grand Theft Auto: San Andreas", a popular and notoriously violent cops and robbers game that turned out to contain hidden sex scenes that could be unlocked using a patch downloaded from the internet. The resulting outcry (mostly from Democratic politicians playing to the centre) caused the game's rating in America to be changed from "mature", which means you have to be 17 to buy it, to "adults only", which means you have to be 18, but also means that big retailers such as Wal-Mart will not stock it. As a result the game has been banned in Australia; and, this autumn, America's Federal Trade Commission will investigate the complaints. That will give gaming's opponents an opportunity to vent their wrath on the industry. Skepticism of new media is a tradition with deep roots, going back at least as far as Socrates' objections to written texts, outlined in Plato's Phaedrus. Socrates worried that relying on written texts, rather than the oral tradition, would "create forgetfulness in the learners' souls, because they will not use their memories; they will trust to the external written characters and not remember of themselves." (He also objected that a written version of a speech was no substitute for the ability to interrogate the speaker, since, when questioned, the text "always gives one unvarying answer". His objection, in short, was that books were not interactive. Perhaps Socrates would have thought more highly of video games.) Novels were once considered too low-brow for university literature courses, but eventually the disapproving professors retired. Waltz music and dancing were condemned in the 19th century; all that twirling was thought to be "intoxicating" and "depraved", and the music was outlawed in some places. Today it is hard to imagine what the fuss was about. And rock and roll was thought to encourage violence, promiscuity and Satanism; but today even grannies buy Coldplay albums.

单选题 Exciting new research indicates that growing older might not necessarily mean growing mentally slower. New studies are providing breakthroughs in our understanding of how aging affects memory, language, and other cognitive functions. This information could provide tools for lessening or even averting some loss in brain functioning often associated with old age. If science can help older citizens retain their mental abilities longer, then the whole nation would benefit. That's why it is so important for research on the aging mind to flourish. The government should make studying neural health, the role of life experiences in shaping the brain, and the structure of the aging mind—key priorities in these years. And the National Institute on Aging should undertake major research initiatives in these areas to expand the scientific basis for understanding and promoting healthy mental aging. Revolutionary advances in neuron-science, behavioral science, and the science of learning have opened the door for the development of new techniques and technologies that can preserve mental sharpness in older people. These might be as novel as transplanting genetically engineered cells to replace disfunctional neurons or as familiar as engaging in stimulating intellectual and physical activities. As many jokes about losing brain cells illustrate, it has long been thought that age-related decline in cognitive abilities is a result of diminishing neurons and synapses. But scientists have discovered that as people grow old, a drop in certain mental abilities may have more to do with changes in the health of the nervous system. For example, the mild loss of memory that is often associated with growing old may be linked to biochemical shifts in neurons rather than to actual loss of brain cells. Research aiming at identifying the mechanisms that maintain or impair neural health is critical for advancing our knowledge of aging. In addition, exciting studies under way around the country are exploring the degree to which older people can benefit from certain kinds of mental practice. We are only beginning to understand the pliability of cognitive functioning in people who are already old, but the promise of finding ways to maintain abilities is very real. For example, studies indicate that our life experiences can bring about lasting changes in our brains that shape how we age. Aging people with college or postgraduate degrees, for instance, generally have better cognitive functioning, such as language and reasoning than those with less education. And better-educated people who reach their 80s—when much of the decline in brain functioning typically occurs—experience far fewer cognitive problems than their less-educated peers. Scientists believe that formal education and professional training lead to more dense and complex associations among neurons that maintain functions even when those associations weaken.

单选题 In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence--as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instinct remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed, the suffering means nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us. The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social program. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law. Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each other's problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. "Talk, talk, talk," the advocates of violence say, "all you ever do is talk, and we are none the wiser." It's rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. "Possibly, my Lord," the barrister replied, "none the wiser, but surely far better informed." Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.
