单选题{{B}}Passage Seven{{/B}} It is hard to track the blue whale, the ocean's largest creature, Which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navy's formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of a exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second--slower than through land but faster than through air. What is most important, different layers of. ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient's chest to a doctor's ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low- frequency ones can often travel thousands of miles.

单选题Ever since this government's term began, the attitude to teachers has been overshadowed by the mantra that good teachers cannot be rewarded if it means bad teachers are rewarded, too. That's why, despite the obvious need for them, big pay rises have not been awarded to teachers across the board. The latest pay rise was 3.6 per cent--mad in the present situation. That's why, as well, the long battle over performance-related pay was fought as teacher numbers slid. The idea is that some kind of year zero can eventually be achieved whereby all the bad teachers are gone and only the good teachers remain. That is why the Government's attempts to relieve the teacher shortage have been so focused on offering incentives to get a new generation of teachers into training. The assumption is that so many of the teachers we have already are bad, that only by starting again can standards be raised. But the teacher shortage is not caused only because of a lack of new teachers coming into the profession. It is also because teaching has a retention problem, with many leaving the profession. These people have their reasons for doing so, which cannot be purely about wanting irresponsibly to "abandon" pupils more permanently. Such an exodus suggests that even beyond the hated union grandstanding, teachers are not happy. Unions and government appear to be in broad agreement that the shortage of teachers is a parlous state of affairs. Oddly, though, they don't seem entirely to agree that the reasons for this may lie in features of the profession itself and the way it is run. Instead, the Government is so suspicious of the idea that teachers may be able to represent themselves, that they have set up the General Teaching Council, a body that will represent teachers whether they want it to or not, and to which they have to pay ￡ 25 a year whether they want to or not. The attitudes of both sides promise to exacerbate rather than solve the problem. Teachers are certainly exacerbating the problem by stressing just how bad things are. Quite a few potential teachers must be put off. And while the Government has made quite a success of convincing the public that bad education is almost exclusively linked to bad teachers represented by destructive unions, it also seems appalling that in a survey last year, working hours for primary teachers averaged 53 hours per week, while secondary teachers clocked up 51 hours. At their spring conferences, the four major teaching unions intend to ballot their members on demanding from government an independent inquiry into working conditions. This follows the McCrone report in Scotland, which produced an agreement to limit hours to 35 per week, with a maximum class contact-time of 22 and a half hours. That sounds most attractive.

单选题{{B}}Passage 2{{/B}} One in three Americans said that money was a crucial factor in their decision to work for pay (or have a spouse work) rather than stay home to raise the children, with Baby Boomer women most likely to have made that choice. Forty-five percent of Baby Boomer women—compared with just 32 percent of those 55 and over—said they went to work. "Baby Boomer women, especially the older ones, grew up expecting to replicate the pattern of their mothers' lives," suggests Hochschild. "But then the bills started coming in and more job opportunities opened up, and these women moved into a life they hadn't anticipated." Money played a great role in marriage—even an unhappy one. Approximately 18 percent of all those interviewed said they stayed married because they lacked money to get a divorce, while less than 8 percent said that financial strain in their marriage has caused them to divorce. Lack of money also influenced education choices. Nearly one in four Americans has postponed or decided not to attend college because of financial pressures. Even with the sustained prosperity of the past eight years, Gen-Xers were most likely to have altered their college plans. A 39-year-old Hispanic billing clerk in New York spoke about how the need for money limited her teenager son's ability to take part in extracurricular activities that could increase his chances of getting into college. "Since age 14, my son's been working, and I think he is a superb person. Not having a lot of money has made him realize what work is all about. On the other hand, he was elected to go to a youth leadership conference in Washington, and I can't send him because I don't have the money. Lack of money takes away opportunities he otherwise could have had." On the question of what money can and can't buy, a large majority of Americans said that money could buy "freedom to live as you choose", "excitement in life", and "less stress". In a number of follow-up interviews, many people commented that having extra money would immediately alleviate one source of profound stress—the need to work overtime. Those with college and graduate degrees were far more likely to believe that money can buy freedom, perhaps because better-educated people already have a wider array of choices. College educated professionals, for instance, were much more likely to consider wealth a way of financing travel, starting a business of their own, or funding charitable works in their communities. A 55-year-old Hispanic woman in Los Angeles with a graduate degree and an income of more than $90,000 described a midlife career switch. After resigning from a high-level, high paying— but extremely stressful—civil service job, she became a florist. "After I started tearing my hair out," she said, "I decided to go into business for myself—flowers don't talk back." Can money buy peace of mind? Fifty-two percent of Americans said no. "It all depends on what 'peace' means to you," observed a businesswoman in California who is nearing 60 and would like to retire at 62 and go back to college. "For my husband, peace of mind means working as long as he can and collecting the biggest possible pension. For me, it means knowing I've worked long enough so that I can afford to go after an old dream. I guess you should say that my peace of mind is his worry."

单选题Works of architecture are so much a part of our environment that we accept them as fixed and scarcely notice them until our attention is summoned. People have long known how to enclose space for the many purposes of life. The spatial aspect of the arts is most obvious in architecture. The architect makes groupings of enclosed spaces and enclosing masses, always keeping in mind the function of the structure, its construction and materials, and, of course, its design—the correlative of the other two. We experience architecture both visually and by moving through and around it, so that we perceive architectural space and mass together. The articulation of space and mass in building is expressed graphically in several ways; the principal ones include plans, sections, and elevations. A plan is essentially a map of floor, showing the placement of the masses of a structure and, therefore, the spaces they bound and enclose. A section, like a vertical plan, shows placement of the masses as if the buildings were cut through along a plane, often along a plane that is a major axis of the building. An elevation is a head-on view of an external or internal wall, showing its features and often other elements that would be visible beyond or before the wall. Our response to a building can range from simple contentment to astonishment and awe. Such reactions are products of our experience of a building's function, construction, and design; we react differently to a church, a gymnasium, and an office building. The very movements we must make to experience one building will differ widely and profoundly from the movements required to experience another. These movements will be controlled by the continuity or discontinuity of its axes. For example, in a central plan—one that radiates from a central point, as in the Pantheon in Rome—we perceive the whole spatial entity at once. In the long axial plan of a Christian basilica or a Gothic cathedral, however, our attention tends to focus on a given point—the altar at the eastern end of the nave. Mass and space can be interrelated to produce effects of great complexity, as, for example, in the Byzantine Church of the Katholikon. Thus, our experience of architecture will be the consequence of a great number of material and formal factors, including training, knowledge, and our perceptual and psychological makeup, which function in our experience of any work of art.
