单选题The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, but this is largely because, unlike animals, we stand upright. This means that our noses are 35 to perceiving those smells which float through the air, missing the majority of smells which stick to surfaces. In fact, though, we are 36 sensitive to smells, even ff we do not generally realize it. Our noses are capable of 37 human smells even when these are diluted to far below one part in one million. Strangely, some people find that they can smell one type of flower but not another, whereas others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate 38 smell receptors in the nose. These receptors are the cells which sense smells and send 39 to the brain. However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when 40 to it often enough. The explanation for insensitivity to smell seems to be that the brain finds it 41 to keep all smell receptors working all the time but can create new receptors if necessary. This may also explain why we are not usually sensitive to our own smells—we 42 do not need to be. We are not 43 of the usual smell of our own house, but we notice new smells when we visit someone else's. The brain finds it best to keep smell receptors available for unfamiliar and 44 signals such as the smell of smoke, which might indicate the danger of fire. A. simply E. permanently I. dedicated M. distinguishing B. emergency F. limited J. exposed N. particular C. aware G. sure K. impulses O. extremely D. detecting H. inefficient L. messages

单选题 Amitai Etzioni is not surprised by the latest headings about scheming corporate crooks(骗子). As a visiting professor at the Harvard Business School in 1989, he ended his work there disgusted with his students' overwhelming lust for money. 'They're taught that profit is all that matters,' he says. 'Many schools don't even offer ethics (伦理学) courses at all.' Etzioni expressed his frustration about the interests of his graduate students. 'By and large, I clearly had not found a way to help classes full of MBAs see that there is more to life than money, power, fame and self-interest,' he wrote at the time. Today he still takes the blame for not educating these 'business-leaders-to-be.' 'I really feel like I failed them,' he says. 'If I was a better teacher maybe I could have reached them.' Etzioni was a respected ethics expert when he arrived at Harvard. He hoped his work at the university would give him insight into how questions of morality could he applied to places where serf-interest flourished. What he found wasn't encouraging. Those would-be executives had, says Etzioni, little interest in concepts of ethics and morality in the boardroom—and their professor was met with blank stares when he urged his students to see business in new and different ways. Etzioni sees the experience at Harvard as an eye-opening one and says there's much about business schools that he'd like to change. 'A lot of the faculty teaching business are bad news them-selves.' Etzioni says. From offering classes that teach students how to legally manipulate contracts, to reinforcing the notion of profit over community interests, Etzioni has seen a lot that's left him shaking his head. And because of what he's seen taught in business schools, he's not surprised by the latest rash of corporate scandals. 'In many ways things have got a lot worse at business schools, I suspect,' says Etzioni. Etzioni is still teaching the sociology of right and wrong and still calling for ethical business leadership. 'People with poor motives will always exist,' he says. 'Sometimes environments con-strain those people and sometimes environments give those people opportunity. 'Etzioni says the booming economy of the last decade enabled those individuals with poor motives to get rich before getting in trouble. His hope now: that the cries for reform will provide more fertile soil for his long-standing messages about business ethics.

单选题With 22 years on the job, Jackie Bracey could be considered a career employee of the Internal Revenue Service. But she defies any stereotype of an over-eager agent running down a reluctant taxpayer. Instead, she spends her time defending people who owe the government money. Ms. Bracey, based in Greensboro N. C., is a taxpayer advocate, a created by Congress in 1998 as part of the kinder, gentler theme adopted by the tax collection agency. Bracey and advocates at 73 Other offices nationwide, backed by 2,100 field workers and staff, go to bat for taxpayers who are in financial straits because of something the agency has done or is about to do. Though it may seem contrary to the IRS, the advocate service not only helps taxpayers, but identifies procedural problems. The main goal, though, is for the ombudsman to step into a dispute a taxpayer is having with the IRS when it appears that something the IRS is doing, or planning, would create an undue hardship on the taxpayer. This can range from speeding up resolution of a dispute that has dragged on too long, to demanding that the IRS halt a collection action that the taxpayer can show he or she “is suffering or is about to suffer a significant hardship.” Taxpayer ombudsmen have been around in one form or another since 1979, says Nina Olson, the national taxpayer advocate. But they were given much more power in 1998 when Congress decided that the workers would no longer report to regional directors but to her office. While this gave them a great deal more authority, outside watchdogs say more can be done. “There is a long way to go to get an agency that feels independent and emboldened to work for taxpayers”, says Joe Seep, a vice president of the Washington-based tax-advocacy group. The taxpayers union also has complained that Congress and the Bush administration don’t seem to be taking the advocates seriously enough. Each year, the IRS group reports to Congress on the top problems that advocates see. Many of these are systemic problems that can gum up the works for both taxpayer and collector, such as a December notice from Ms. Olson that the IRS should have just one definition of a dependent child, rather than the three definitions currently used. While taxpayer advocates can help smooth things out in many cases, they cannot ignore laws. If taxpayers haven’t made legitimate claims for credits, there’s nothing the advocate can do to reverse that course. And Olson says that while taxpayers are free to use her service, they should keep in mind that it does not replace the normal appeals process and should be the last place a citizen calls upon for help, not the first. “We’re really there for .when the processes fall down,” she says. Every state has at least one taxpayer-advocate service office.
