单选题Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-mom to make offers, or "bids", for the 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 table at which he stands. This is often set on a raised platform called a rostrum. The ancient Romans probably invented sales by auction, and the English word comes from the Latin auctio, meaning "increase". The Romans usually sold in this way the spoils taken in war; these sales were called sub basra, 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 stayed alight. Practically all goods whose qualities vary are sold by auction. Among these are coffee, hides, skins, wool, tea, cocoa, furs, spices, fruit and vegetables and wines. Auction sales are also usual for land and property, antique furniture, pictures, rare books, old china and similar works of art. The auction roams at Christie'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 prospective 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 1 and continue in numerical order; he may wait until he registers the fact that certain dealers 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 as high as possible. The auctioneer must know fairly accurately the current market values of the goods he is selling, and he should be acquainted with regular buyers of such goods. He will not waste time by starting the bidding too low. He will also play on the rivalries among his buyers and succeed in getting a high price by encouraging two business competitors to bid against each other. It is largely on his advice that a seller will fix a "reserve" price, that is, a price below which the goods cannot be sold. Even the best auctioneers, however, find it difficult to stop a "knock out", whereby dealers illegally arrange beforehand not to bid against each other, but nominate one of themselves as the only bidder, in the hope of buying goods at extremely low prices. If such a "knock-out" comes off, the real auction sale takes place privately afterwards among the dealers.

单选题There are some that would argue that hospitals are no place for dogs, while they are wrong. At least according to new research reported at the American Heart Association's Scientific Sessions 2005. For people hospitalized with advanced heart disease, it is better to have visitors than to lie quietly alone. But one type of visitor seems to be especially beneficial, researchers reported on Tuesday. That visitor is a dog. In the first controlled study of the effects of pet therapy in a random sample of acute and critically ill heart patients, anxiety as measured on a standard rating scale dropped 24 percent for those visited by a dog and a human volunteer, by 10 percent for those visited by a volunteer alone and not at all for those with no visitors. Similar results were found in measures of heart and lung function. The senior author of the Pet Therapy Study, Kathie M. Cole, said 76 patients with heart failure, a condition that affects an estimated five million Americans, were randomly assigned one of the three visit types. The dogs, from 12 breeds, were screened for behavior and disease before participating in the study. "Some patients in the first group," Ms. Cole said, "began to smile and immediately engaged in conversation with dog and volunteer. " "Their worries seemed to vanish fiom their faces," she said. The researchers examined the patients three times: right before the 12-minute visit, eight minutes into it and tour minutes after it was over. Besides the anxiety measurement, researchers found, patients' levels of epinephrine, a hormone the body makes when under stress, dropped 17 percent when visited by a person and a dog, and 2 percent when visited by only a person. Epinephrine levels rose an average of 7 percent in the unvisited group in the study, which was financed by the Pet Care Trust Foundation, a nonprofit group. Pressure in the heart's top left chamber dropped 10 percent after a visit by volunteer and dog. The same pressure rose 3 percent for those visited by a volunteer and 5 percent for the unvisited group. Pressure in the pulmonary artery dropped 5 percent during and after a visit by volunteer and dog, but rose in the other two groups. Ms. Cole recommended further studies to determine how long the benefits lasted. "Dogs are a great comfort," she said. "They make people happier, calmer and feel more loved. That is huge when you are scared and not feeling well. /
