单选题 Being in charge has its benefits: More money, more control, more power, and apparently, more job satisfaction. Recently the Pew Research Center released data from a survey that found bosses are happier than workers in their jobs. 69% of the people in management positions from the survey said they were satisfied with their current positions, compared with just 48% of rank-and-file (普通的) workers. The manager respondents were also more likely than non-managers to say they consider their work a career rather than merely a job (78% vs. 44%) and were much less likely to be looking for a job than those who don't manage others (12% vs. 23%). They're also more likely to be happy with their lives outside of work, to feel they're paid fairly for what they do, and to think having children hasn't been a hindrance to their advancement. While those numbers may not be surprising given the age, greater income and longer careers of those typically in management, the report did find that both managers and non-managers value the exact same things (and in the exact same order) when considering a job. Enjoyable work comes first, followed by job security and then the ability to take time off to care for family. Similarly low numbers of participants cited a big salary (just 20% of bosses and 18% of workers) and opportunities for advancement (25% vs. 24%) as being important, despite presumably different access to each. Also surprising, says Rich Morin, senior editor of Pew's Social Demographic Trends project, was how similar numbers of bosses and employees considered problems such as gender discrimination to be a social issue. 62% of managers and 66% of workers agree that the country needs to make changes to solve gender inequality (不平等) issues in the workplace. 'It wasn't a case of big bad bosses and exploited workers,' Morin says. 'That was an optimistic finding. On these important issues, they think alike.' Perhaps most notable, meanwhile, is that despite the greater satisfaction and lower stress associated with being in charge, fewer people want to become managers than not. Just 39% of people responding to Pew's study said they would like such a position; 43% said they wouldn't. (The remaining 18% included those who were already managers and a few who didn't answer.) 'Some people simply don't want the headaches that come with being a boss, and some simply don't want the long hours,' Morin says, acknowledging the contradiction between that statement and Pew's findings. For many, it seems, the satisfaction that comes from greater control and more money simply doesn't outweigh the potential perils (危险) of being the one in charge.

单选题 How many really suffer as a result of labor market problems? This is one of the most critical yet contentious social policy questions. In many ways, our social statistics exaggerate the degree of hardship. Unemployment does not have the same dire consequences today as it did in the 1930s, when most of the unemployed were primary bread winners, when income and earnings were usually much closer to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the over-whelming majority are from multiple-earner, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies. Yet there are also many ways our social statistics underestimate the degree of labor-market-related hardship. The unemployment counts exclude the millions of fully employed workers whose wages are so low that their families remain in poverty. Low wages and repeated or prolonged unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find full-time work, or else outside the labor force but wanting a job. Finally, income transfers in our country have always focused on the elderly, disabled, and dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and inkind transfers does not necessarily mean that those failing in the labor market are adequately protected. As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate—that the existing poverty, employment, and earnings statistics are inadequate for one their primary applications, measuring the consequences of labor market problems.

单选题 At the base of a mountain in Tanzania's Gregory Rift, Lake Natron burns bright red, surrounded by the remains of animals that were unfortunate enough to fall into the salty water. Bats, swallows and more are chemically preserved in the pose in which they perished, sealed in the deposits of sodium carbonate in the water. The lake's landscape is bizarre and deadly—and made even more so by the fact that it's the place where nearly 75 percent of the world's flamingos (火烈鸟) are born. The water is so corrosive that it can burn the skin and eyes of unadapted animals. Flamingos, however, are the only species that actually makes life in the midst of all that death. Once every three or four years, when conditions are right, the lake is covered with the pink birds as they stop flight to breed. Three-quarters of the world's flamingos fly over from other salt lakes in the Rift Valley and nest on salt-crystal islands that appear when the water is at a specific level—too high and the birds can't build their nests, too low and predators can move briskly across the lake bed and attack. When the water hits the fight level, the baby birds are kept safe from predators by a corrosive ditch. 'Flamingos have evolved very leathery skin on their legs so they can tolerate the salt water,' says David Harper, a professor at the University of Leicester. 'Humans cannot, and would die if their legs were exposed for any length of time.' So far this year, water levels have been too high for the flamingos to nest. Some fish, too, have had limited success vacationing at the lake as less salty lagoons (泻湖) form on the outer edges from hot springs flowing into Lake Natron. Three species of tilapia (罗非鱼) thrive there part-time. 'Fish have a refuge in the streams and can expand into the lagoons when the lake is low and the lagoons are separate,' Harper said. 'All the lagoons join when the lake is high and fish must retreat to their stream refuges or die.' Otherwise, no fish are able to survive in the naturally toxic lake. This unique ecosystem may soon be under pressure. The Tanzanian government has once again started mining the lake for soda ash, used for making chemicals, glass and detergents. Although the planned operation will be located more than 40miles away, drawing the soda ash in through pipelines, conservationists worry it could still upset the natural water cycle and breeding grounds. For now, though, life prevails—even in a lake that kills almost everything it touches.
