单选题Auctions are public sales of goods, conducted by an officially approved auctioneer. He asked the crowd to gather in the auction room to bid for various items on sale. He encourages buyers to bid higher figures and finally names the highest bidder as the buyer of the goods. This is called "knocking down" the goods, for the bidding ends when the auctioneer bangs a small hammer on a raised platform. The ancient Romans probably invented sales by auction and the English word comes from the Latin "autic", meaning "increase". The Romans usually sold in this way the spoils taken in war; these sales were called "sub hasta", meaning "under the spear", a spear being stuck in the ground as a signal for a crowd to gather. In England in the eighteenth and nineteenth centuries goods were often sold "by the candle"; a short candle was lit by the auctioneer and bids could be made while it was burning. Practically all goods can be sold by auction. Among these are coffee, skins, wool, tea, cocoa, furs, fruit, vegetables and wines. Auction sales are also usual for land and property, antique furniture, pictures, rare books, old china and works of art. The auction rooms at Chritie's and Sotheby's in London and New York are world famous. An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by the buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a "lot", is usually given a number. The auctioneer need not begin with lot one and continue the numerical order; he may wait until he notices the fact that certain buyers are in the room and then produce the lots they are likely to be interested in. The auctioneer's services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding.

单选题In the world of climate change, it is in the Earth's cold regions where trends can most easily be seen. The cryosphere, where water is found in solid form, is among the most sensitive regions to temperature change. The sensitivity of ice and snow to temperature changes is an early indicator of even relatively small differences, says University of Colorado at Boulder senior researcher Richard Armstrong. He has found that today's receding and thinning sea ice, mountain glacier mass losses, decreasing snow extent, melting permafrost (永久冻土), and rising sea level are all consistent with warming. Global mean temperatures have risen one degree Fahrenheit over the past 100 years. with more than half of the increase occurring in the last 25 years, observes Armstrong who is affiliated with the National Snow and Ice Data Center headquartered at CU-Boulder. "As slight as that may seem, it's enough to make a difference, " said Armstrong. "Now, long-term monitoring of a series of cold region, or cryospheric, parameters (参数) shows that for several decades the amounts of snow and ice around the world have been decreasing. " The extent of Arctic sea ice is shrinking by about 3 percent per decade. but the trends are not uniform. While recent studies have indicated that the ice thickness also had decreased over several decades, new information shows that the ice may have thinned rapidly, Armstrong said. Examination of springtime ice thickness in the Arctic Ocean indicates that the mean ice thickness decreased 1.5 meters (4.8 feet) between the mid-1980s and early 1990s. To mark its 25th anniversary, the National Snow and Ice Data Center has organized a special session at the 2001 Fall Meeting of American Geophysical Union, taking place this week in San Francisco, that illuminates overall changes in the cryosphere. The session begins Tuesday and extends through Thursday afternoon, with 75 contributions from all areas of cryospheric study. Papers and posters include examinations of lake and river ice, glacier dynamics, and mass ice balance studies in polar and continental glaciers, regional and polar snow cover trends, and variations in Canadian ice cap elevations.

单选题New parents are annoying. They think you want to hear about every gurgle and baby-step. But it could be worse. When your boss has a sprog, watch your wallet. A study to be published next month in Administrative Science Quarterly looks at what happens to workers' pay when a male boss has a child. Researchers tracked salaries at every firm in Denmark with more than ten employees between 1996 and 2006.(They confined themselves to male bosses partly because the sample of female bosses was too small.) Male bosses, it turns out, pay themselves significantly more once they become fathers. Even after controlling for factors such as age, length of tenure and the performance of the firm, the study found that bosses with daughters pay themselves 3.5% more than childless ones. If they have a son, that increases to a hefty 6.4% . David Ross of Columbia Business School, one of the authors, says all fathers feel a duty to support their families. For grunts this means working harder. Bosses have the more agreeable option of raising their own wages. This is bad news for underlings. That extra money comes out of workers' pockets, the study finds. Staff employed by a father is typically paid less. The amount depends on such things as the sex of the baby and whether it is his first child. Male employees bear the brunt: if the boss's child is a son, for example, they can expect 0. 5% less salary than if he hadn't reproduced. Female staff fare better. After their boss's first child, they can expect to be paid a little more. Mr Ross speculates that this might be because, having seen their wives go through childbirth, they start to respect women more. Alas, such goodwill doesn't last. Once the boss has a second child, female workers' wages are likely to fall, just like men's.

单选题Two main techniques have been used for training elephants, which we may call respectively the tough and the gentle. The former method simply consists of setting an elephant to work and beating him until he does what is expected. Apart from any moral considerations this is a stupid method of training, for it produces a resentful animal who at a later stage may well turn man-killer. The gentle method requires more patience in the early stages, but produces a cheerful, good-tempered elephant who will give many years of loyal service. The first essential in elephant training is to assign to the animal a single mahout who will be entirely responsible for the job. Elephants like to have one master just as dogs do, and are capable of a considerable degree of personal affection. There are even stories of half-trained elephant calves who have refused to feed and pained to death when by some unavoidable circumstance they have been deprived of their own trainer. Such extreme cases must probably be taken with a grain of salt, but they do underline the general principle that the relationship between elephant and mahout is the key to successful training. The most economical age to capture an elephant for training is between fifteen and twenty years, for it is then almost ready to undertake heavy work and can begin to earn its keep straight away. But animals of this age do not easily become subservient to man, and a very firm hand must be employed in the early stages. The captive elephant, still roped to a tree, plunges and screams every time a man approaches, and for several days will probably refuse all food through anger and fear. Sometimes a tame elephant is tethered nearby to give the wild one confidence, and in most cases the captive gradually quietens down and begins to accept its food. The next stage is to get the elephant to the training establishment, a ticklish business which is achieved with the aid of two tame elephants roped to the captive on either side. When several elephants are being trained at one time, it is customary for the new arrival to be placed between the stalls of two captives whose training is already well advanced. It is then left completely undisturbed with plenty of food and water so that it can absorb the atmosphere of its new home and see that nothing particularly alarming is happening to its companions when it is eating normally, its own training begins. The trainer stands in front of the elephant holding a long stick with a sharp metal point. Two assistants, mounted on tame elephants, control the captive from either side, while others rub their hands over his skin to the accompaniment of a monotonous and soothing chant. This is supposed to induce pleasurable sensations in the elephant, and its effects are reinforced by the use of endearing epithets, such as 'ho! my son', or 'ho! My father', or 'my mother' according to the age and sex of the captive. The elephant is not immediately susceptible to such blandishments, however, and usually lashes fiercely with its trunk in all directions. These movements are controlled by the trainer with the metal-pointed stick, and the trunk eventually becomes so sore that the elephant curls it up and seldom afterwards uses it for offensive purposes.

单选题To a philosopher, wisdom is not the same as knowledge. Facts may be known in enormous numbers without the knower of them loving wisdom. Indeed, the person who possesses encyclopedic (学士渊博的) information may actually have a genuine contempt (轻视) for those who love and seek wisdom. The philosopher is not content with a mere knowledge of facts. He desires to combine and evaluate facts, and to examine beneath the obvious to the deeper orderliness behind the immediately given facts. Insight into the hidden depths of reality, perspective (洞察) on human life and nature in their entirety, in the words of Plato, to be a spectator of time and existence-these are the philosopher's objectives. Too great an interest in the small details of science, may, and often does, obscure these basic objectives. Philosophers assume that the love of wisdom is a natural gift of the human being. Potentially every man is a philosopher because in the depths of his being there is an intense longing to penetrate to the meaning of the mysteries of existence. The inner deep longing expresses itself in various ways prior to any actual study of philosophy as a technical branch of human culture. Consequently every human being in so far as he has ever been or is a lover of wisdom has, to that extent, a philosophy of life.

单选题Sharks have gained an unfair reputation for being fierce predators of large sea animals. Humanity's unfounded fear and hatred of these ancient creatures is leading to a worldwide slaughter that may result in the extinction of many larger, coastal shark species. The shark is the victim of a warped attitude of wildlife protection: we strive only to protect the beautiful, nonthreatening parts of our environment. And, in our efforts to restore only nonthreatening parts of our earth, we ignore other important parts. A perfect illustration of this attitude is the contrasting attitude towards another large sea animal, the dolphin. During the 1980s, environmentalists in the U. S. A. protested the use of driftnets for tuna fishing in the Pacific Ocean since these nets also caught dolphins. The environmentalists generated enough political and economic pressure to prevent tuna companies from buying tuna that had been caught in driftnets. In contrast to this effort, the populations of sharks in the Pacific Ocean have decreased to the point of extinction and there has been very little effort by the same environmentalists to save this important species, of marine wildlife. Sharks are among the oldest creatures on earth, having survived in the seas for more than 350 million years. They are extremely efficient animals, feeding on wounded or dying animals, thus performing an important role in nature of weeding out the weaker animals in a species. Just the fact that species such as the Great White Shark have managed to live in the oceans for so many millions of years is enough proof of their efficiency and adaptability to changing environments. It is time for humans, who may not survive another 1000 years at the rate they are damaging the planet, to east away their fears and begin considering the protection of sharks as creatures that may provide us insight into our own survival.
