单选题Like many Americans, Mark Seery watched the Virginia Tech school shooting unfold on the cable news networks in April 2007. It wasn"t just the catastrophe that disturbed him—it was how some psychologists were advising the campus community to respond in the wake of the devastating tragedy. "There"s a sense that"s very much alive within the professional community that if people don"t talk about what they"re feeling, and try to suppress it, somehow it will only rebound down the road and make things worse," says Seery, an assistant professor of psychology at the University of Buffalo. That, says Seery, is one of many examples of situations in which the first response to a tragedy"s psychological ramifications is to encourage victims and bystanders to talk about their emotions in the wake of the event. That idea is constantly reinforced by a battery of television therapists who harp on the importance of sharing your feelings. But is that really the best medicine? Seery"s new research offers an alternative to that philosophy. His work suggests that those who do not reveal their feelings in the wake of a collective trauma turn out just fine, if not better, than those who do. Seery used an online survey to query a national sample about their reactions to the 9/11 attacks, beginning on the day itself. The respondents were divided into two groups: those who said they were initially unwilling to talk about their feelings, and the rest. At the end of the two-year survey period, those who decided not to share their feelings reported fewer related mental and physical problems. That effect was even more pronounced among those who lived close to the tragedy. Seery also found an interesting correlation between the level of sharing and well-being. Participants could decide how much they wanted to report about their feelings on the survey. Seery found that there was a correlation between those who wrote the lengthier, more in-depth descriptions of their feelings and those who had worse mental and physical statuses. Does the study turn conventional wisdom completely on its head, suggesting that it"s better to stay quiet in the aftermath of a traumatic event? Not quite. Seery explains that the respondents who felt the need to divulge their emotions started off in a worse mental and physical state in the first place, likely a bit more susceptible to the stress of a collective traumatic event. "The people who were talking were probably more distressed by the event," says Seery. "The initial distress motivated them to want to have some place to talk about it...whereas people who chose not to talk were less likely to say that they were trying cope." The take-home message, then, is that there is no one right way to react to traumatic events; there is a wide range of normal and healthy responses to tragedy.

单选题Around the world more and more people are taking part in dangerous sports and activities. Of course, there have always been people who have looked for adventure—those who have climbed the highest mountains, explored unknown parts of the world or sailed in small boats across the greatest oceans. Now, however, there are people who seek an immediate excitement from a risky activity which may only last a few minutes or even seconds. I would consider bungee jumping to be a good example of such an activity. You jump from a high place(perhaps a bridge or a hot-air balloon)200 meters above the ground with an elastic rope tied to your ankles. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is estimated that two million people around the world have now tried bungee jumping. Other activities which most people would say are as risky as bungee jumping involve jumping from tall buildings and diving into the sea from the top of high cliffs. Why do people take part in such activities as these? Some psychologists suggest that it is because life in modern societies has become safe and boring. Not very long ago, people's lives were constantly under threat. They had to go out and hunt for food, diseases could not easily be cured, and life was a continuous battle for survival. Nowadays, according to many people, life offers little excitement. They live and work in comparatively safe environment; they buy food in shops; and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to seek danger in activities such as bungee jumping.

Mark your answer on ANSWER SHEET 1. {{B}}Text 1{{/B}} Children attending schools located in high-traffic zones have a 45 percent increased risk of developing asthma, even though time spent at school only accounts for about one-third of a child's waking hours, according to new research. Asthma is the most common chronic childhood illness in developed countries and has been linked to environmental factors such as traffic-related air pollution. "While residential traffic-related pollution has been associated with asthma, there has been little study of the effects of traffic exposure at school on new onset asthma," says Rob McConnell, professor of preventive medicine at USC's Keck School of Medicine. "Exposure to pollution at locations other than home, especially where children spend a large portion of their day and may engage in physical activity, appears to influence asthma risk as well." The study appears online in the journal Environmental Health Perspectives. The study drew upon data from the Children's Health Study (CHS), a longitudinal study of children in Southern California communities that was designed to investigate the chronic effects of air pollution on respiratory health. Using a cohort of 2 497 kindergarten and first grade children who were asthma-free when they entered the study, researchers examined the relationship of local traffic around schools and homes to diagnosis new onset asthma that occurred during three years of follow-up. Traffic-related pollution exposure was assessed based on a model that took into account traffic volume, distance to major roadways from home and school and local weather conditions. Regional ambient ozone, nitrogen dioxide (二氧化氮) and particulate matter were measured continuously at one central site in each of the 13 study communities. The design allowed investigators to examine the joint effects of local traffic-related pollution exposure at school and at home and of regional pollution exposure affecting the entire community. Researchers found 120 cases of new asthma. The risk associated with traffic-related pollution exposure at schools was almost as high as for residential exposure, and combined exposure accounting for time spent at home and at school had a slightly larger effect. Although children spend less time at school than at home, physical education, and other activities that take place at school may increase ventilation rates and the dose of pollutants getting into the lungs, McConnell notes. Traffic-related pollutant levels may also be higher during the morning hours when children are arriving at school. Despite a state law that prohibits school districts from building campuses within 500 feet of a freeway, many Southern California schools are located near high-traffic areas, including busy surface streets. "It's important to understand how these micro-environments where children spent a lot of their time outside of the home are impacting their health," McConnell says. "Policies that reduce exposure to high-traffic environments may help to prevent this disease. " The study was funded by grants from the National Institute of Environmental Health Sciences, the US Environmental Protection Agency, the South Coast Air Quality Management District, and the Hastings Foundation.

单选题{{B}}Passage Three{{/B}} The word science is heard so often in modern times that almost everybody has some notion of its meaning. On the other hand, its definition is difficult for many people. The meaning of the term is confused, but everyone should understand its meaning and objectives. Just to make the explanation as simple as possible, suppose science is defined as classified knowledge (facts). Even in the true sciences distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example, hypotheses and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited. The exact statue of any explanation should be clearly labeled to avoid confusion. The objectives of science are primarily the discovery and the subsequent understanding of the unknown. Man cannot be satisfied with recognizing that secrets exist in nature or that questions are unanswerable; he must solve them. Toward that end specialists in the field of biology and related fields of interest are directing much of their time and energy. Actually, two basic approaches lead to the discovery of new information. One, aimed at satisfying curiosity, is referred to as pure science. The other is aimed at using knowledge for specific purposes—for instance, improving health, raising standards of living, or creating new consumer products. In this case knowledge is put to economic use. Such an approach is referred to as applied science. Sometimes practical-minded people miss the point of pure science in thinking only of its immediate application for economic rewards. Chemists responsible for many of the discoveries could hardly have anticipated that their findings would one day result in application of such a practical nature as those directly related to life and death. The discoveries of one bit of information opens the door to the discovery of another. Some discoveries seem so simple that one is amazed they were not made years ago; however, one should remember that the 'construction of the microscope had to precede the discovery of the cell. The host of scientists dedicating their lives to pure science are not apologetic about ignoring the practical side of their discoveries; they know from experience that most knowledge is eventually applied.

单选题Our trouble lies in a simple confusion, one to which economists have been prone since the beginning of the Industrial Revolution. Growth and ecology operate by different rules. Economists tend to assume that every problem of scarcity can be solved by substitution, by replacing tuna with tilapia, without factoring in the long-term environmental implications of either. But whereas economies might expand, ecosystems do not. They change--pine gives way to oak, coyotes arrive in New England--and they reproduce themselves, but they do not increase in extent or abundance year after year. Most economists think of scarcity as a labor problem. Imagining that only energy and technology place limits on production. To harvest more wood, build a better chain saw; to pump more oil, drill more wells; to get more food, invent pest-resistant plants. That logic thrived on new frontiers and more intensive production, and it held off the prophets of scarcity- from Thomas Robert Malthus to Paul Ehrlich- whose predictions of famine and shortage have not come to pass. The Agricultural Revolution that began in seventeenth-centur) England radically increased the amount of food that could be grown on an acre of land, and the same happened in the 1960s and 1970s when fertilizer and hybridized seeds arrived in India and Mexico. But the picture looks entirely different when we change the scale. Industrial society is roughly 250 years old: make the last ten thousand years equal to twenty-four hours, and we have been producing consumer goods and CO 2 for only the last thirty-six minutes. Do the same for the past 1 million years of human evolution, and every thing from the steam engine to the search engine fits into the past twenty-one seconds. If we are not careful, hunting and gathering will look like a far more successful strategy of survival than economic growth. The latter has changed sc much about the earth and human societies in so little time that it makes more sense to be cautious than triumphant. Although food scarcity, when it occurs, is a localized problem, other kinds of scarcity are already here. Groundwater is alarmingly low in regions all over the world, but the most immediate threat to growth is surely petroleum.

单选题A study released a little over a week ago, which found that eldest children end up, on average, with slightly higher IQ's than younger siblings, was a reminder that the fight for self-definition starts much earlier than freshman year. Families, whatever the relative intelligence of their members, often treat the firstborn as if he or she were the most academic, and the younger siblings fill in other niches: the wild one, the flirt. These imposed caricatures, in combination with the other labels that accumulate from the sandbox through adolescence, can seem over time like a miserable entourage of identities that can be silenced only with hours of therapy. But there's another way to see these alternate identities: as challenges that can sharpen psychological skills. In a country where reinvention is considered a birthright, many people seem to treat old identities the way Houdini treated padlocked boxes: something to wriggle free from, before being dragged down. And psychological research suggests that this ability can be a sign of mental resilience, of taking control of your own story rather than being trapped by it. The late-night bull sessions in college or at backyard barbecues are at some level like out-of-body experiences, allowing a re-coloring of past experience to connect with new acquaintances. A more obvious outlet to expand identity—and one that's available to those who have not or cannot escape the family and community where they're known and labeled—is the Internet. Admittedly, a lot of the role-playing on the Internet can have a deviant quality. But researchers have found that many people who play life-simulation games, for example, set up the kind of families they would like to have had, even script alternate versions of their own role in the family or in a peer group. Decades ago the psychologist Erik Erickson conceived of middle age as a stage of life defined by a tension between stagnation and generativity-a healthy sense of guiding and nourishing the next generation, of helping the community. Ina series of studies, the Northwestern psychologist Dan P. McAdams has found that adults in their 40s and 50s whose lives show this generous quality—who often volunteer, who have a sense of accomplishment—tell very similar stories about how they came to be who they are. Whether they grew up in rural poverty or with views of Central Park, they told their life stories as series of redemptive lessons. When they failed a grade, they found a wonderful tutor, and later made the honor roll; when fired From a good job, they were forced to start their own business. This similarity in narrative constructions most likely reflects some agency, a willful reshaping and re-imagining of the past that informs the present. These are people who, whether pegged as nerds or rebels or plodders, have taken control of the stories that form their identities. In conversation, people are often willing to hand out thumbnail descriptions of themselves:" I'm kind of a hermit." Or a talker, a practical joker, a striver, a snob, a morning person. But they are more likely to wince when someone else describes them so authoritatively. Maybe that's because they have come too far, shaken off enough old labels already. Like escape artists with a lifetime's experience slipping through chains, they don't want or need any additional work. Because while most people can leave their family niches, schoolyard nicknames and high school reputations behind, they don't ever entirely forget them.
