单选题The chief problem in coping with foreign motorists is not so much remembering that they are different from you, but that they are enormously variable. Cross a frontier without adjusting and you can be in deep trouble. One of the greatest gulfs separating the driving nations is the Atlantic Ocean. More precisely, it is the mental distance between the European and the American motorist, particularly the South American motorist. Compare, for example, an English driver at a set of traffic lights with a Brazilian. Very rarely will an Englishman try to anticipate the green light by moving off prematurely. You will find the occasional sharpie who watches for the amber to come up on the adjacent set of lights. However, he will not go until he receives the lawful signal. Brazilians view the thing quite differently. If, in fact, they see traffic lights at all, they regard them as a kind of roadside decoration. The natives of North America are much more disciplined. They demonstrate this in their addiction to driving in one lane and sticking to it—even if it means settling behind some great truck for many miles. To prevent other drivers from falling into reckless ways, American motorists try always to stay close behind the vehicle in front which can make it impossible, when all the vehicles are moving at about 55 mph, to make a real lane change. European visitors are constantly falling into this trap. They return to the Old World still flapping their arms in frustration because while driving in the State in their car they kept failing to get off the highway when they wanted to and were swept along to the next city. However, one nation above all others lives scrupulously by its traffic regulations—the Swiss. In Switzerland, if you were simply to anticipate a traffic light, the chances are that the motorist behind you would take your number and report you to the police. What is more, the police would visit you; and you would be convicted. The Swiss take their rules of the road so seriously that a diver can be ordered to appear in court and charged for speeding on hearsay alone, and very likely found guilty. There are slight regional variations among the French, German and Italian speaking areas, but it is generally safe to assume that any car bearing a CH sticker will be driven with a high degree of discipline.

单选题To say that the child learns by imitation and that the way to teach is to set a good example oversimplifies. No child imitates every action he sees. Sometimes, the example the parent wants him to follow is ignored while he takes over contrary patterns from some other example. Therefore we must turn to a more subtle theory than "Monkey see, monkey do." Look at it from the child"s point of view. Here he is in a new situation, lacking a ready response. He is seeking a response which will gain certain ends. If he lacks a ready response for the situation, and cannot reason out what to do, he observes a model who seems able to get the right result. The child looks for an authority or expert who can show what to do. There is a second element at work in this situation. The child may be able to attain his immediate goal only to find that his method brings criticism from people who observe him. When shouting across the house achieves his immediate end of delivering a message, he is told emphatically that such a racket is unpleasant, that he should walk into the next room and say his say quietly. Thus, the desire to solve any objective situation is overlaid with the desire to solve it properly. One of the early things the child learns is that he gets more affection and approval when his parents like his response. Then other adults reward some actions and criticize others. If one is to maintain the support of others and his own self-respect, he must adopt responses his social group approves. In finding trial responses, the learner does not choose models at random. He imitates the person who seems a good person to be like, rather than a person whose social status he wishes to avoid. If the pupil wants to be a good violinist, he will observe and try to copy the techniques of capable players; while some other person may most influence his approach to books. Admiration of one quality often leads us to admire a person as a whole, and he becomes an identifying figure. We use some people as models over a wide range of situations, imitating much that they do. We learn that they are dependable and rewarding models because imitating them leads to success.

单选题Companies that advertise on television complain that digital television recording (DTR) services make it possible for consumers to watch television programs without viewing the commercials that these advertisers have paid the television networks to broadcast. The DTR service providers respond that their services may actually help the advertisers, because without their service, many consumers would not have been able to watch the programs--or the commercials in them--in the first place. Which of the following, if true, offers the most support to the advertisers' claims that the DTR services are currently hurting their businesses? A. Even the best commercials are usually less entertaining than the programs that consumers choose to watch for themselves. B. DTR services charge such high rates that only a small percentage of consumers subscribe to them. C. The average per-second cost of advertising on television has risen every year for the past two decades. D. More than 90 percent of subscribers to DTR services opt to use a setting that automatically edits out commercials. E. DTR services alter the television viewing experience by allowing customers to view the program of their choice at the time of their choosing.

单选题For most of the 20th century, the solution to the mystery of the original Americans—where did they come from when, and how? —seemed as clear as the geography of the Bering Strait, the climate of the last ice age, and the ubiquity of finely wrought stone hunting weapons known as Clovis points. According to the ruling theory, bands of big-game hunters trekked out of Siberia sometime before 11,500 years ago. They crossed into Alaska when the floor of the Bering Strait, drained dry by the accumulation of water in a frozen world"s massive glaciers, was a land bridge between continents. And found themselves in a trackless continent, the New World when it was truly new. The hunters, so the story went, moved south through a corridor between glaciers and soon flourished on the Great Plains and in the Southwest of what is now he United States, their presence widely marked by distinctive stone projectile points first discovered near the town of Clovis, New Mexico. In less than 1,000 years, these Clovis people and their distinctive stone points made it all the way to the tip of South America. They were presumably the founding population of today"s American Indians. Now a growing body of intriguing evidence is telling a much different story. From Alaska to Brazil and southern Chile, artifacts and skeletons are forcing archaeologists to abandon Clovis orthodoxy and come to arms with a more complex picture of earliest American settlement. People may have arrived thousands to tens of thousands of years sooner, in many waves of migration and by a number of routes. Their ancestry may not have been only Asian. Some of the migrations may have originated in Australia or Europe.
