单选题{{B}}Passage Two{{/B}} The idea of building "New Towns" to absorb growth is frequently considered a cure-all for urban problems. It is wrongly assumed that if new residents can be diverted from existing centers, the present urban situation at least will get no worse. It is further and equally wrongly assumed that since European New Towns have been financially and socially successful, we can expect the same sorts of results in the United States. Present planning, thinking, and legislation will not produce the kinds of New Town that have been successful abroad. It will multiply suburbs or encourage developments in areas where land is cheap and construction profitable rather than where New Towns are genuinely needed. Such ill-considered projects not only will fail to relieve pressures on existing cities but will, in fact, tend to weaken those cities further by drawing away high-income citizens and increasing the concentration of low-income groups that are unable to provide tax income. The remaining taxpayers, accordingly, will face increasing burdens, and industry and commerce will seek escape. Unfortunately, this mechanism is already at work in some metropolitan areas. The promoters of New Towns so far in the United States have been developers, builders, and financial institutions. The main interest of these promoters is economic gain. Furthermore, federal regulations designed to promote the New Town idea do not consider social needs as the European New Town plans do. In fact, our regulations specify virtually all the ingredients of the typical suburban community, with a bit of political rhetoric (修辞) thrown in. A workable American New Town formula should be established as firmly here as the national formula was in Britain. All possible social and governmental innovations as well as financial factors should be thoroughly considered and accommodated (容纳) in this policy. Its objectives should be clearly stated, and both incentives and penalties should be provided to ensure that the objectives are pursued. If such a policy is developed, then the New Town approach can play an important role in alleviating America's urban problems.

单选题Most students are usually introduced to the study of history by way of a fat textbook and be-come quickly immersed in a vast sea of names, dates, events, and statistics. The students" skills are then tested by examinations that require them to show how much of the data they remember. From this experience a number of conclusions seem obvious: the study of history is the study of "facts" about the past; the more "facts" you know, the better you are as a student of history. But in this way students may become confused upon discovering that historians often disagree sharply. They discover that historians dealing with the same event may come to quite different conclusions about it. Obviously, there is no easy solution to this problem. Historians disagree because each histo-rian views the past from a particular perspective. Once students grasp this, they have taken the first step toward being able to evaluate the work of various historians. But before they can take this first step, students must consider a problem they have more or less taken for granted. They must ask themselves what history really is. The word history has several meanings. In its broadest sense, it denotes the whole of the hu-man past. More restricted is the notion that history is the recorded past, that is, that part of hu-man life which has left some sort of record such as folk tales, artifacts, or written documents. Fi-nally, history may be defined as that which historians write about the past.

单选题For some people, the light of human attention has an unbearable brilliance. Like ivy along the dim edge of a garden, they prefer the social shadows, shunning parties, publicity and fame of any sort. Then there are the flowers of the human arboretum. For them, being in the view of others seems necessary for life itself. From Hollywood to fabricated prime-time reality, this spotlight-dependent species is thriving. But what about the individuals who crave attention for more desperate reasons? Those who resort to unusual ways to get it? Lately, it seems, a dark bloom of these characters has emerged. For motives known only to themselves, they have won notoriety by drawing on an almost sacred well of social status, victim hood. In early April, US national news outlets tracked the disappearance of Audrey Seiler, a sophomore at the University of Wisconsin in Madison. Police and hundreds of concerned citizens searched for four days before Seiler was discovered. Seiler said she was kidnapped. Within hours, however, her story fell apart. Police announced that her abduction had been a hoax. Why would a popular student make herself disappear? Her motive remains a mystery, but perhaps it had something to do with the search parties and the news bulletins that surrounded her. Sympathy is a powerful sentiment that can connect complete strangers. But if it's used to manipulate, the backlash can be much more intense. In February, a Waterbury, Connecticut, man was arrested as a result of exploiting sympathy. Edward Valentin told reporters that he had received word that his wife, serving in Iraq, had been killed in an explosion. Police said Valentin admitted the fabrication, reasoning that if people felt sorry for him maybe the military would send his wife home. Evidence, however, points elsewhere. In its extreme form, such a craving shows up in mental disorders, where sufferers may seek attention by causing themselves harm. But even when it comes with no diagnosis, a deep craving to be noticed can have a wide impact. For these individuals, victim hood represents a "pure state of guilt-free entitlement," said psychologist Richard Levak, of Del Mar, California. "They go from being utterly deprived to being utterly indulged. In today's world ... people have become more depressed and disconnected from each other. So you get people who crave affection and attention and approval. They don't know how to ask for it and they don't know how to get it. That leaves them vulnerable. " Levak said.

单选题{{B}}Passage Four{{/B}} Before the summer of 2000, the 54 year old John Haughom could accomplish just about any thing at work. "I could move mountains if I put my mind to it."he says of those days. But that summer Haughom found he couldn't move them any more. On the phone with his wife one morn ing, Haughom broke down. A couple of days later Haughom checked himself in for a three-week stay at the Professional Renewal Center, an in-patient clinic 30 miles outside Kansas City that helps him deal with stress. Haughom is far from alone. A host of new studies and plenty of anecdotal evidence show that stress in the workplace is skyrocketing. Whatever the cause, stress levels are at record highs. The statistics are startling. According to a new study by the federal government's Nation al Institute for Occupational Safety and Health, more than half the working people in the U.S. view job stress as a major problem in their lives. This year the European Community officially dubbed stress the second-biggest occupational-health problem facing the continent. Ten years ago experts warned that stress was out of control, in part because of a shaky economy. What's notable about today's wave of stressed-out workers is that it rises all the way to the top. Lack of control is generally considered one of the biggest job stressors, so it used to be thought that middle managers carried the brunt: sandwiched between the top and the bottom, they end up with little authority. Powerful chief executive officers (CEOs) were seen as the least threatened by stress. But in today's tough economy, top executives don't have as much control as they used to. "Stress is just part of the job, fortunately or unfortunately, stress'is part of our character building," Lebenthal says. "But I think I don't need any more character building. What I need is a vacation." But if you think that going on vacation is hard—and studies show that 85%of corporate executives don't use all the time off they're entitled to. Being able to handle stress is perhaps the most basic of job expectations. So among the corporate elite, succumbing to it is considered a shameful weakness. Stress has become the last affliction that people won't dare admit to. Most senior executives who are undergoing treatment for stress—and even many who aren't—refused to talk on the record about the topic．"Nothing good can come out of having your name in a story like this," one CEO said through his therapist.

单选题 There is no question that some "greenwashing" is going on in the corporate world. Bayern-werk, a Bavarian utility, began selling "Aqua Power" last year when Germany began to let customers choose their electricity supplier. Bayern-werk markets Aqua Power as 100 percent green, renewable, hydroelectric energy. But any customer who signs up gets power from the same mix of sources as before: hydro, gas, coal and nuclear. Nothing changes except some accounting, and there is no net benefit to the environment. There is a benefit, though, to Bayernwerk, which charges more for Aqua Power and has been swamped with orders for it. Greenwashing takes many forms. "Companies often advertise themselves as environmentally friendly even though they might have some pretty hideous environment records," says Jill Johnson of the group Earth Day 2002. California's PG＆E, the utility that settled out of court after the real Erin Brockovich accused it of polluting groundwater, runs pro-environmental ads. But PG＆E is due in court in November on charges of polluting wells in a second California town. "PG＆E has a very good environmental track record," says spokesman Greg Pruett, citing recycling and waste reduction. Weyerhaeuser, the timber company, cuts old-growth trees in Canada but trumpets the 100 million tree seedlings it will plant this year. Overall, the greening of corporate America is real and has not been as hard to achieve as some environmental activists imagined. That is especially true for greenhouse gases and climate change, the focus of Earth Day 2000. "Now there is more recognition by companies that there may be an economic advantage to reducing emissions of greenhouse gases," says Paul Portney, president of the think tank Resources for the Future. More and more companies are changing the way they heat and light their buildings and design their factories to reduce greenhouse gas emissions as well as their energy bills. (Energy-efficiency upgrades can save a company roughly $1 per square foot of office or factory space every year.) The reductions often exceed those called for in the 1997 international agreement on greenhouse warming called Kyoto Treaty, whose goal of reducing greenhouse emissions 7 percent from their 2000 levels is deemed so threatening to the economy by many oil, coal and chemical companies that the White House does not dare to submit to the Senate for ratification.
