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 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 hid 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All Eskimos live most of their lives close to salt or fresh water. They may follow game inland for several hundred miles, but they always return to the shores of rivers, lakes or seas. Eskimo land has a bare look. Large rocks, pebbles, and sand cover much of the surface. Plants called lichen grow right on rocks. And where there is enough soil, ever grass, flowers and small bushes manage to live. No trees can grow on the Eskimo land, so geographers sometimes call this country the Arctic plains. Some animals, such as rabbits and caribou, eat the plants. Others, like the white fox and grey wolf, eat the rabbits and caribou. The Eskimo is a meat-eater, too, and may even eat a wolf when food is scarce. The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall almost too short to be noticed. Summer is the good time, when food is usually plentiful. But it is also the time when the Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store. For seldom can enough animals be killed in winter to feed a family. The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21 st and August 21 st , the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sun shining at all. Around Oct. 21 st the Eskimos of Northern Greenland see the sun setting straight south of them, and they don"t see it again until February 22 nd . All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker. Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and the moon provide a little light. The northern lights also help the Eskimos to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo"s eyes.
