单选题Auctions(拍卖) 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Who takes care of the elderly in the United States today? The fact is that family members provide over 80% of the care that elderly people need. In most cases the elderly live in their own homes. A very small percentage of America"s elderly people live in nursing homes. Samuel Preston, a sociologist at the University of Pennsylvania, studied how the American family is changing. He reported that by the time the average American couple reaches about 40 years of age, their parents are usually still alive. The statistics show the change in lifestyles and responsibilities of aging Americans. The average middle aged couple can look forward to caring for elderly parents sometime after their own children have grown up. Moreover, because people today live longer after an illness than people did years ago, family members must provide long-term care. These facts also mean that after caregivers provide for their elderly parents, who will eventually die, they will be old and may require care too. When they do, their husbands or wives will probably take care of them because they have had fewer children than their parents did. Because Americans are living longer than ever, more social workers have begun to study ways of care giving to improve the care of the elderly. They have found that all caregivers share a common characteristic: They believe that they are the best people for the job. The social workers have also discovered three basic reasons why the caregivers take on the responsibility of caring for an elderly, dependent relative. Many caregivers believe they had an obligation to help their relatives. Some think that helping others makes them feel more useful. Others hope that by helping someone now, they will deserve care when they become old and dependent.
