单选题Before the summer of 2000, the 54-year-old John Haughom could accomplish just about anything 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 morning, 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 National 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Proper arrangement of classroom space is important to encouraging interaction. Most of us have noticed how important physical setting is to efficiency and comfort in our work. College classroom space should be designed to encourage the activity of critical thinking. We may be approaching the twenty-first century, but step into almost any college classroom and you step back in time at least a hundred years. Desks are normally in straight rows, so students can clearly see the teacher but not all their classmates. The assumption behind such an arrangement is obvious. Everything of importance comes from the teacher. With a little imagination and effort, unless desks are fixed to the floor, the teacher can correct this situation and create space that encourages interchange among students. In small or standard-size classes, chairs, desks, and tables can be arranged in a variety of ways. The primary goal should be for everyone to be able to see everyone else. Larger classes, particularly those held in lecture halls, unfortunately, allow much less flexibility. Arrangement of the classroom should also make it easy to divide students into small groups for discussion or problem-solving exercises. Small classes with movable desks and tables present no problem. Even in large lecture halls, it is possible for students to turn around and form groups of four to six. Breaking a class into small groups provides more opportunities for students to interact with each other, think out loud, and see how other students' thinking processes operate all essential elements in developing new modes of critical thinking. In courses that regularly use a small group format, students might be asked to stay in the same small groups throughout the course. A colleague of mine, John, allows students to move around during the first two weeks, until they find a group they are comfortable with. John then asks them to stay in the same seat, with the same group, from that time on. This not only creates a comfortable setting for interaction but helps him learn students' names and faces.

单选题First of course, it is plain that in the year 2010 everyone will have at his elbow several times more mechanical energy than he has today. Second, there will be advances in biological knowledge as farreaching as those that have been made in physics. We are only beginning to learn that we can control our biological environ-ment as well as our physical one. Starvation has been prophesied twice to a growing world population: by Malthus about 1800, by Crookes about 1900. It was headed off the first time by taking agriculture to America and the second time by using the new fertilizers. In the year 2010 star-vation will be headed off by the control of the diseases and the heredity (遗传性) of plants and animals—by shaping our own biological environment. And third, I come back to the haunting theme of automation. The most common species in the factory today is the man who works or minds a simple machine—the operator. By the year 2010, he will be as extinct as the hand-loom weaver and the dodo. The repetitive tasks of indus-try will be taken over by the machines, as the heavy tasks were taken over long ago; and the mental tedium (疲劳，沉闷) will go the way of physical exhaustion. Today we still distinguish, even among repetitive jobs, between the skilled and the unskilled, but in the year 2010 all repetition will be unskilled. We simply waste our time if we oppose this change, it is as inevitable as the year 2010 itself.

单选题States are considering major changes in prepaid college tuition programs—raising prices, restricting participation or canceling them—as they grapple with financial woes. Nationwide, families will likely have to pay more to participate, or accept that they might not cover tuition when children go to college. Colorado has closed its prepaid plan to new investors and told existing ones that it may not cover future tuition increases. Wisconsin stopped selling its plan Dec. 20. Maryland and Illinois are among states hiking prices by 20% or more. Prepaid plans let parents lock in tuition by paying for it now, protecting them against rising costs. But the bear market has hurt investment returns, leaving the plans unable to keep up with big increases in tuition. So far, Colorado is the only state that has told participants their investments may not cover tuition, and no plan has missed a payment. Other states have said they will fulfill obligations, even if it requires a legislative bailout. Still, the financial problems have forced thousands to grapple with uncertainty—something prepaid plans were designed to avoid. More than 1 million families have an estimated $ 8 billion invested in the plans, says (SavingforCollege. com) . Some states, including Colorado, may replace the prepaid plan with a guaranteed investment contract, a CD-like investment that's backed by an insurance company. Investors get a minimum rate of return, but no guarantee that it will cover tuition. Wisconsin's EdVest program is encouraging investment in a stable value fund, which is similar to a guaranteed investment contract, in its investment plan. Wisconsin's prepaid plan never guaranteed to cover tuition inflation. It also never got a lot of investors, possibly because it lacked that guarantee. In Florida, a task force is considering limiting the state's prepaid program to low-income families. Ohio officials are also looking at limiting participation, but it's a measure they hope to avoid. "Program administrators are looking for alternatives," says Andrea Feirstein, a state-plan consultant. Maryland recently boosted its prices by up to 30% ; Illinois by up to 23%. The increases have made some prepaid plans uneconomical for parents of older children. In Ohio, the price of one year's tuition for a child over 12 months old is $8,000, more than 40% above current tuition at Ohio State. So it may not be a good deal for children starting college in three or four years because tuition may not jump that much that fast.

单选题{{B}}Passage Three{{/B}} Immigrants are consumers as well as producers, so they create jobs as well as taking them. And the work they do need not be at the expense of native workers. Immigrants often hold jobs that natives are unwilling to accept at any feasible wage. Also, immigrants sometimes help to keep industries viable (能存活的) that would otherwise disappear altogether, causing employment to fall. This was the conclusion of a study of the Los Angeles garment industry in the 1970s and 1980s. And when immigrants working for low wages do put downward pressure on natives' wages, they may raise the (real) wages of natives in general by keeping prices lower than they otherwise would be. In theory, then, the net effect of immigration on native wages is uncertain. Unfortunately, most of the empirical (经验主义的) research on whether immigrants make natives worse off in practice is also inconclusive except the effect, one way or the other, seems small. Most of this research has been done in America: if there were any marked influence on wages, that is where you would expect to find it, given the scale of immigration and the tendency of the newcomers to concentrate in certain areas. But most studies have compared wages and employment in areas with many immigrants to wages and employment in areas with few. For instance, one examined the impact of sudden and notorious inflow of refugees to Miami from the Cuban port of Mariel in 1980. Within the space of a few months, 125 000 people had arrived, increasing Miami's labor force by 7%. Yet the study concluded that wages and employment among the city's natives, including the unskilled, were virtually unaffected. Another study examined the effect of immigration on wages and employment of those at the bottom of the jobs ladder—unskilled blacks and Hispanics. It found that a doubling of the rate of immigration had no detectable effect on natives. The most recent work, admittedly, has tended to question these findings. Using more detailed statistics and more sophisticated methods than the earlier studies, this work has tended to find that immigrants' wages take longer to rise to the level of the natives' wages than has been supposed. This implies a more persistent downward pressure on the host economy's labor market. Typically these studies find that immigration does depress unskilled natives' wages to a small extent. But nearly all economists would agree that the effects of immigration are insignificant in relation to other influences.
