单选题As the horizons of science have expanded, two main groups of scientists have emerged. One is the pure scientist; the other, the applied scientist. The pure or theoretical scientist does original research in order to understand the basic laws of nature that govern our world. The applied scientist adapts this knowledge to practical problems. Neither is more important than the other, however, for the two groups are very much related. Some times, however, the applied scientist finds the "problem" for the theoretical scientist to work on. Let' s take a particular problem of the aircraft industry: heat-resistant metals. Many of the metals and alloys which perform satisfactorily in a car cannot be used in a jet-propelled plane. New alloys must be used, because the jet engine operates at a much higher temperature than an automobile engine. The turbine wheel in a turbojet must withstand temperatures as high as 1,600 degrees Fahrenheit, so aircraft designers had to turn to the research metallurgist for the development of metals and alloys that would do the job in jet-propelled planes. Dividing scientists into two groups is only one broad way of classifying them, however. When scientific knowledge was very limited, there was no need for men to specialize. Today, with the great body of scientific knowledge, scientists specialize in many different fields. Within each field, there is even further subdivision. And, with finer and finer subdivisions, the various sciences have become more and more interrelated until no one branch is entirely independent of the others. Many new specialties--geophysics and biochemistry, for example--have resulted from combining the knowledge of two or more sciences.

单选题{{B}}阅读理解三{{/B}} Questions 11 to 15 are based on the following passage. Most of us have seen a dog staring at, sometimes snarling at, and approaching a reflection of itself. For most animals, seeing their own image in a mirror acts as a social stimulus. But does the dog recognize itself, or does the reflection simply signal a potential companion or threat? This question is interest for a number of reasons. Apart from curiosity about the level of animals' understanding, research on self-recognition in animals has several benefits. It provides some insight into the evolutionary significance of this skill of self- recognition and into the level and kinds of cognitive competence that the skill requires. Such research also indicates the kinds of learning experiences that determine the development of self-recognition. In addition, work with animals fosters the use of techniques that are not dependent on verbal responses and that may therefore be suitable for use with preverbal children. The evidence indicates that dogs and almost all other nonhumans do not recognize themselves. In a series of clever experiments, however, Gallup has shown that the chimpanzee does have this capacity. Gallup exposed chimpanzees in a small cage to a full-length mirror for ten consecutive days. It was observed that over this period of time the number of self-directed responses increased. These behaviors included grooming parts of the body while watching the results, guiding fingers in the mirror, and picking at teeth with the aid of the mirror. Describing one chimp, Gallup said, "Marge used the mirror to play with and inspect the bottom of her feet; she also looked at herself up-side down in the mirror while suspended by her feet from the top of the cage; she was also observed to stuff celery leaves up her nose using the mirror for purposes of visually, guiding the stems into each nostril. " Then the researchers devised a further test of self-recognition. The chimps were anesthetized and marks were placed over their eyebrows and behind their ears, areas the chimps could not directly observe. The mirror was temporarily removed from the cage, and baseline data regarding their attempts to touch these areas were recorded. The data clearly suggest that chimps do recognize themselves, or are self-aware, for their attempts to touch the marks increased when they viewed themselves. Citing further evidence for this argument, Gallup noted that chimpanzees with no prior mirror experience did not direct behavior to the marks when they were first exposed to the mirror; that is, the other chimpanzees appeared to have remembered what they looked like and do have responded to the marks because they noticed changes in their appearance.

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.
