单选题NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive experiences in nightmares. Now American researchers are developing a pill which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased. The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. " Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. " This could relieve a lot of that suffering. " But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us avoid the mistakes of the past. " All of us can think of bad events in our lives that were horrible at the time but they can make us who we are. I'm not sure we want to wipe those memories out," said Rebecca Dresser, a medical ethicist.

单选题 There are seven passages in this part. Each is followed by five questions or unfinished statements. Choose the one out of the choices marked by A, B, C, and D and mark your answer on the Answer Sheet with ●.{{B}}Passage One{{/B}} Researchers disagree whether the "use it or lose it" philosophy holds for cognitive aging, but there is one evidence that keeping mentally active can slow age-related declines. At Pennsylvania State University, Sherry Willis and her husband, K. Warner Schaie, have studied 5000 people, some since 1956. People lucky enough to avoid chronic diseases may also fare better in intellectual function, they find, perhaps because chronic diseases can restrict lifestyle and reduce mental stimulation. Similarly, those lucky enough to be relatively affluent also fare better, perhaps because money can buy intellectually stimulating things like travel. Education helps, too, researchers say because of instills the conviction that you can always learn something new. The Schaie-Willis team also has some other observations. Being in a stable marriage with a stimulating spouse, they say, helps maintain intellectual vigor. Flexibility counts too. People who stay mentally vibrant are often those who do not insist that "they must do things today as they did before" Schaie says. In neuropsychological terms, the ability to see problems in new ways often yields higher scores on tests of-mental function. And people satisfied with life also stay more mentally fit, he says. If you find your mental skills sagging, consider working on specific deficits. When Willis gave 5-hour tutorials on inductive reasoning or spatial skills to about 200 people whose skills had declined in the previous 14 years, 40 percent regained lost abilities. That advantage held up seven years late when they were retested. Other ways to stay sharp, Schaie says, are doing jigsaw puzzles to hone visuo-spatial skills, working crossword puzzles for verbal skills, playing bridge for memory and simply matching wits at home with players on TV game shows. Finally, remember this. Even though you may lose some mental skills with normal aging, you also gain in one key area: wisdom. The growth of wisdom continues throughout the 40s, 50s and even 60s.

单选题No matter what you think about testing rends, one thing is clear: as long as there is teaching and learning, there will be testing. But how much credit do those charts and numbers deserve? When you review a school"s test scores at a school board meeting, always look beyond the basic numbers. The scores for a single school in a single year have limited value for judging school performance. Equally important is "trend data" —test scores from several years that show you how a school"s performance has changed over time. Additionally, comparing a school to other schools with similar demographics may give your perspective on where the school stands relative to other schools like it. You can also learn a lot from data that is broken down by ethnic group and socioeconomic level. A school is only truly successful when it achieves high performance with students across all ethnic and social groups. On the other hand, the next time you hear somebody say, "That school is the best in the district because it has the highest test scores," make a point to respond: "I"d love to know more about what"s happening at the school that accounts for those scores, but I can"t assume that it"s the best school just based on one piece of evidence. What you know about the school"s teaching methods, the leadership of the principal, or its climate of safety?" Take time to investigate these other measures of school quality before making judgments about a school. To communicate with your child certainly is the final way. Raise your hand if you"ve heard some stories about students begging to stay home on test day. Is this level of anxiety appropriate? The correct answer is no! When your child"s class is preparing for its annual standardized testing marathon, let your child know that while you hope she does her best on the test, it"s not a competition. Explain that the results may help her and her teacher understand the areas where she might be especially strong or where she may need to focus more.

单选题The simple act of surrendering a telephone number to a store clerk may not seem harmful—so much so that many consumers do it with no questions asked. Yet that one action can set in motion a cascade of silent events, as that data point is acquired, analyzed, categorized, stored and sold over and over again. Future attacks on your privacy may come from anywhere, from anyone with money to purchase that phone number you surrendered. If you doubt the multiplier effect, consider your E-mail inbox. If it's loaded with spam, it's undoubtedly because at some point in time you unknowingly surrendered your E-mail to the wrong Web site. Do you think your telephone number or address is handled differently? A cottage industry of small companies with names you've probably never heard of—like Acxiom or Merlin—buy and sell your personal information the way other commodities like corn or cattle futures are bartered. You may think your cell phone is unlisted, but if you've ever ordered a pizza, it might not be. Merlin is one of many commercial data brokers that advertises sale of unlisted phone numbers compiled from various sources— including pizza delivery companies. These unintended, unpredictable consequences that flow from simple actions make privacy issues difficult to grasp, and grapple with. In a larger sense, privacy also is often cast as a tale of "Big Brother" —the government is watching you or a big corporation is watching you. But privacy issues don't necessarily involve large faceless institutions: A spouse takes a casual glance at her husband's Blackberry, a co-worker looks at E-mail over your shoulder or a friend glances at a cell phone text message from the next seat on the bus. While very little of this is news to anyone—people are now well aware there are video cameras and Internet cookies everywhere—there is abundant evidence that people live their lives ignorant of the monitoring, assuming a mythical level of privacy, people write E-mails and type instant messages they never expect anyone to see. Just ask Mark Foley or even Bill Gates, whose E-mails were a cornerstone of the Justice Department's antitrust case against Microsoft. And polls and studies have repeatedly shown that Americans are indifferent to privacy concerns. The general defense for such indifference is summed up a single phrase: "I have nothing to hide." If you have nothing to hide, why shouldn't the government be able to peek at your phone records, your wife see your E-mails or a company send you junk mails? It's a powerful argument, one that privacy advocates spend considerable time discussing and strategizing over. It is hard to deny, however, that people behave differently when they're being watched. And it is also impossible to deny that Americans are now being watched more than at any time in history.

单选题{{B}}Text 4{{/B}} A key reason the news media exists with special privileges is to be our watchdogs. Reporters' charge is to alert us when something is wrong, when human or natural disasters are about to threaten our welfare. When it comes to natural disasters, the news media do a praisable job of reporting the obvious, but not a very good one of preparing the public for what might happen, for alerting us to potential difficulties. When it comes to human disasters, especially problems in government and economic matters, the press has failed miserably. For example, Time magazine finally told the public in a recent cover story what only the most quick observers already knew: "The Great Retirement Ripoff (偷窃): Millions of Americans who think they will retire with benefits are going be shocked. How corporations are picking people's pockets—with the help of Congress...How can this legal?" Where was the media when each piece of corporate-biased legislation was being passed? Why wasn't Congress afraid to pass such legislation? Because the media has decided that news concerning Congress is of little interest to its audience. TV news managers have believed that economic and social issues are too complicated for the public to grasp. Newspaper editors occasionally print such stories, but mostly they concentrate on human-interest features, consumer health sections and entertainment. Hard news holes are shrinking and investigative journalism is carried out only on occasion. It is too difficult and costly. Besides, it antagonizes advertisers while seldom increasing circulation. Magazines that would look into such subjects seem to be dying out. The result is that no one is watching the rich and powerful so they can do almost anything with impunity (不受惩罚). Millions of Americans have been robbed in broad daylight while the news media has busied itself with celebrity trials and sensational crime stories. Corporations steal the public blind under legislation authorized by government officials. Companies file for bankruptcy protection, cutting off medical and life-insurance benefits for retirees. It isn't a new phenomenon. For the most part, today's press has let down the American public time and time again. If it seems to be getting worse, it's because there are so many segments of the media that should be telling us, in an accurate and fair manner, what our elected officials are doing before it's too late to take action. It's harder to blame corporations because they make no bones about their mission: make as much money as possible at all costs. Those in Congress are supposed to protect us and look out for our interests. Yet, it appears they constantly help their powerful supporters who often buy their offices for them. No one is doing the right thing. The joke apparently is on all of us—the old and the sick who will have no help in the future and the young burdened with the debt of caring for their impoverished elders for the rest of their lives.

单选题Battles are like marriages. They have a certain fundamental experience they share in common; they differ infinitely, but still they are all alike. A battle seems to me a conflict of will with death in the same way that a marriage of love is the identification of two human beings to the end of creation of life--as death is the reverse of life, and love of hate. Battles are commitments to cause death as marriages are commitments to create life. Whether, for any individual, either union results in death or in the creation of life, each risks it--and in the risk commits himself. As the servants of death, battles will always remain horrible. Those who are fascinated by them are being fascinated by death. There is no battle aim worthy of the name except that of ending all battles. Any other conception is, literally, suicidal. The fascist worship of battle is a suicidal drive; it is love of death instead of life. In the same idiom, to triumph in battle over the forces which are fighting for death is-- again literally--to triumph over death. It is a surgeon's triumph as he cuts a body and bloodies his hands in removing a cancer in order to triumph over death that is in the body. In these thoughts I have found my own peace, and I return to an army that fights death and cynicism in the name of life and hope. It is a good army. Believe in it.

单选题Whether the cause is maternal anti-bodies, heavy metals or something else, there is no question that the brains of young children with autism have unusual features. To begin with, they tend to be too big. In studies based on magnetic resonance imaging (MRI) and basic tape-measure readings, neuroscientist Eric Courchesne at Children"s Hospital of San Diego showed that while children with autism are born with ordinary-size brains, they experience a rapid expansion by age 2—particularly in the frontal lobes. By age 4, says Courchesne, autistic children tend to have brains the size of a normal 13-year-old. More recent studies by Admiral and others have found that the amygdale, an area associated with social behavior, is also oversize, a finding Admiral believes is related to the high levels of anxiety seen in as many as 80% of people with autism. Harvard pediatric neurologist Dr. Martha Herbert reported last year that the excess white matter in autistic brains has a specific distribution: local areas tend to be overconnected, while links between more distant regions of the brain are weak. The brain"s right and left hemispheres are also poorly connected. It"s as if there are too many competing local services but no long distance. This observation jibes neatly with imagining studies that look at live brain activity in autistic people. Studies using functional MRI show a lack of coordination among brain regions, says Marcel Just, director of Carnegie Mellon"s Center for Cognitive Brain Imaging in Pittsburgh, Pa. Just has scanned dozens of 15-to 35-year-old autistic people with IQs in the normal range, giving them thinking tasks as he monitors their brain activity. "One thing you see," says Just, "is that activity in different areas is not going up and down at the same time. There"s a lack of synchronization, sort of like a difference between a jam session and a string quartet. In autism, each area does its own thing." What remains unclear is whether the interconnectivity problem is the result of autism or its cause. "It"s impossible to tell the chicken from the egg at this point," Just says. Autistic people have been shown to use their brains in unusual ways: they memorize alphabet characters in a part of the brain that ordinarily processes shapes. They tend to use the visual centers in the back of the brain for tasks usually handled by the prefrontal cortex. They often look at the mouth instead of the eyes of someone who is speaking. Their focus, says psychologist Ami Klin of Yale"s Child Study Center, is "not on the social allegiances—for example, the longing gaze of a mother—but physical allegiances—a mouth that moves."

单选题Terrorism proves to be a more serious problem than anticipated, and it challenges both policymakers burdened with the design of countermeasures and social scientists who are called upon to explain it. Terrorism's unique nature is revealed by two phenomena. First, public perception of threat and danger seems to be disproportionate to terrorists' actual capabilities. Second, terrorism, more than any other form of warfare, has an impact on a target group immensely larger than that of the immediate victims and often on populations beyond that terrorism bears primarily on individuals' perceptions, on the "public mind"; in other words, it is a form of psychological warfare. The psychological impacts of political terrorism are potentially manifest in individuals' emotional and attitudinal responses. In the realm of emotions, the fear and concern for personal safety, which terror tactics might give rise to, is a revealing indicator of their effectiveness. One could argue, of course, that terrorists' ability to sow widespread fear hardly needs proof as it is obvious that violence and particularly the terrorists' hallmark, randomly targeted violence, are anxiety inducing. It should be noted, however, that terrorism has claimed relatively few casualties to date, and that in most countries the actual probability of incurring harm from terroristic activity is only a fraction of, say, the risk of death or injury in vehicle accidents or common crimes. Hence, the power of terrorism to intimidate should not be taken for granted. Intimidation and the induction of fear are not the ends of terrorists' activity but rather means to effect political change. Their violence is predicated on two assumptions: (a) Violent action can force the causes pursued by terrorists into the forefront of an indifferent public's awareness; (b) faced with the choice between continuing violence and acceptance of the terrorists' demands, the public might opt for the latter. Thus, the attitudes that the targets of political terrorism develop toward its perpetrators, their objectives, and the actions that ought to be undertaken vis-à-vis them constitute telling measures of the effectiveness of terrorism. The present investigation sought to assess the psychological reactions of a public which has been exposed for a considerable length of time to the threats and actions of terrorist. Regarding emotional impacts, the data suggest that terrorism's ability to intimidate, to induce worry and concern, disproportionally exceeds the actual damage it causes. According to the data gathered, the actual probability of being victimized by terrorist activity was extremely low; estimated at less than 1/20 of the likelihood of being hurt in a road accident. Yet a large majority of the respondents expressed worry about the risk of personally incurring the consequences of terrorism. It might be uncontrollability dramatically enhance its impact. Thus, while the risk of vehicle driving might be far greater than the danger of terrorism, the car driver is usually reassured by a subjective feeling of control which the potential victim of terrorism lacks. The survey results indicate that terrorism has failed to produce the change in attitudes sought by its perpetrators. Most respondents favored, instead, the reliance on extreme counterterrorist measures. The hardening of Israelis attitudes toward terrorists and their objectives was also revealed by the respondents' unanimity of opinion. Taken together, the data concerning the emotional impact of terrorism and its effects on attitudes did not bear out the rationale which governs terroristic action. Despite the widespread concern and worry revealed by these data, there was no evidence of any willingness to politically concede to terrorists. On the contrary, and as already noted, the majority advocated the adoption of harsh measures against terrorists. Thus, at least insofar as Palestinian terrorism and the Israeli public are concerned, proves to be counterproductive. Comprehension Questions..
