单选题Many objects in daily use have clearly been influenced by science, but their form and function, their dimensions and appearance were determined by technologists, artisans, designers, inventors, and engineers using nonscientific modes of thought. Many features and qualities of the objects that a technologist thinks about can't be reduced to unambiguous verbal descriptions; they are dealt with in the mind by a visual, nonverbal process. In the development of Western technology, it has been nonverbal thinking, by and large, that has fixed the outlines and filled in the details, and rockets exist not because of geometry or thermodynamics, but because they were first a picture in the minds of those who built them. The creative shaping process of a technologist's mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress individual ways of non-verbal thinking on the machine by continually using an intuitive sense of rightness and fitness. What would be the shape of the combustion chamber? Where should be the valves placed? Should it have a long or short piston? Such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available space, and not least by a sense of form. Some decisions, such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary. Design courses, then, should be an essential element in engineering curricula. Nonverbal thinking, a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. Because perceptive processes are not assumed, to entail "hard thinking", nonverbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal or mathematical thought. But it is paradoxical that when the staff of the Historic American Engineering Record wished to have drawings made of machines and isometric views of industrial processes for its historical record of American engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools. If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to en- counter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are not merely trivial aberrations; they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.

单选题{{B}}Text 4{{/B}} Cyberspace, data superhighway, multi-media—for those who have seen the future, the linking of computers, television and telephones will change our lives forever. Yet for all the talk of a forthcoming technological utopia little attention has been given to the implications of these developments for the poor. As with all new high technology, while the West concerns itself with the "how". the question of "for whom" is put aside once again. Economists are only now realizing the full extent to which the communications revolution has affected the world economy. Information technology allows the extension of trade across geographical and industrial boundaries, and transnational corporations take full advantage of it. Terms of trade, exchange and interest rates and money movements are more important than the production of goods. The electronic economy made possible by information technology allows the haves to increase their control on global markets--with destructive impact on the have-nots. For them the result is instability. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine. As "futures" are traded on computer screens, developing countries simply have less and less control of their destinies. So what are the options for regaining control? One alternative is for developing countries to buy the latest computers and telecommunications themselves—so-called "development communications" modernization. Yet this leads to long-term dependency and perhaps permanent constraints on developing countries' economies. Communications technology is generally exported from the U. S., Europe or Japan; the patents, skills and ability to manufacture remain in the hands of a few industrialized countries. It is also expensive, and imported products and services must therefore be bought on credit--credit usually provided by the very countries whose companies stand to gain. Furthermore. when new technology is introduced there is often too low a level of expertise to exploit it for native development. This means that while local elites, foreign communities and subsidiaries of transnational corporations may benefit, those whose lives depend on access to the information denied it.

单选题I wish to meet you to______ for my rudeness on Saturday this week.

单选题The crowd ______ into the hall and some had to stand outside.

单选题It is a treasure hunt with a difference: conducted not with metal detectors, but by negotiation. Italy is at last reaping the benefits of a two-year campaign to regain smuggled antiquities. Five American museums have been talked into returning works that they claim to have acquired in good faith. Almost 70 of the finest are now on display in Rome—and they have just been joined by the only known intact work by Euphronios, an Athenian vase-painter. New ground is also being broken with the return of nine items from the private collection of a New York philanthropist, Shelby White. This is the first pact negotiated with an individual. Francesco Rutelli, the culture minister, met Ms White twice in America before the deal was done. She has always maintained that she and her late husband had no idea that the pieces were suspect. A tenth item from their collection, also by Euphronios, is being sent back to Italy in 2010. Under Italian law, any classical artefacts found on Italian soil belong to the state, even if (like Euphronios" vases) they originated in Greece. A former head of the J. Paul Getty Museum in Los Angeles and an American art dealer have been on trial for almost three years in Rome, charged with trafficking in illegally excavated objects. Both deny wrongdoing. Their charge was followed by a deal that officials say is crucial for efforts to curb the traffic in smuggled antiquities. Switzerland has undertaken to require importers of classical artifacts to produce proofs of origin and of legal export. The deals with the museums have all involved give-and-take. In exchange for works claimed by Italy, the museums have been given others on long-term loan. "Italian lovers of art and archaeology will get back what has been stolen, while others abroad will profit from the exhibition of sometimes even more beautiful works," says Mr Rutelli. The deal with the Getty museum was the hardest to do but also the most productive. 40 of the works on show in Rome come from there. But they do not include the "Getty bronze", which the Italians had hoped to retrieve. This third-century BC statue, attributed to Lysippos, Greek sculptor, was caught by Italian fishermen in 1964. The Getty insists that it was found in international waters. The Italians say it was still illegally exported.

单选题Up until the age of 18, I read very little. I 1 myself to what was necessary for a secondary-school 2 . I was always busy either playing soccer or falling in love. Then came the day when, as a young columnist, my main 3 was to read. And I got to like it. My head spun! An unknown passion took 4 of me. What happened? For me, it was the 5 of a new state of being in love. I began to take possession of books and to annotate them. 6 I would tell them, in an only slightly 7 way, how much I liked them or didn"t. Today, 25 years later, I 8 through my books from those days and it"s magic, finding myself face to face with the young man I once was. Sometimes I 9 him. Other times I find him 10 Certain remarks seem 11 to me now. Others make me happy. I was right about that, I sometimes say to myself. Twenty-five years later I find the 12 trace of my thoughts, my 13 of that time. That"s why I never lend out my books. I give 14 the ones of which I have two 15 and the ones I"ve never read. But the ones I"ve 16 up cannot 17 : they have become my journals, my 18 . To let someone read them would be 19 myself up to scrutiny. I would be allowing others to break into me like a 20 breaks into a house.
