单选题{{B}}Passage 2{{/B}} 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Almost since the beginning of mankind, governments have been recording the numbers of their populace. The first known census report took place in 3800 B. C. in Babylonia for the purpose of deciding who should pay taxes. As time went by, governments found other, more creative uses for knowing their numbers. Egyptian King Ramses II used the census not only to determine who should pay taxes, but also to figure out how to divide land for farming and to decide who could provide manpower for various government projects. These new ideas came about in the mid-1200s-B. C. William the Conqueror brought the concept of census taking to England in 1085. All landowners were required to name their holdings for the purpose of taxation. By the fifteenth century, Tudor kings found a new twist to the Egyptians' use of the census. They too used the population count as a means of getting ready manpower for important government projects, namely, replenishing troops in the ongoing battles in western Europe. A rebellious tide swept over England, however, in the mid-1700s. A bill to authorize a regular census was defeated in Parliament on the grounds that it would give valuable information to England's enemies. But the tide of rebellion soon turned, and in 1800 England established its first regular census. Meanwhile the United States had already had an ongoing census for ten years. It was authorized in the Constitution for the purpose of deciding how many members of Congress would be needed for a fair representation of the American people. The constitutional article also established that the census would be taken in 1790 and every ten years thereafter. And so it has. Since its beginning, the American census has gone through many changes. Today the census provides more than a count of the people who live here. It takes polls on transportation, economic planning, and agriculture. The census also provides data for most government agency statistics, such as the unemployment rate. Counting costs have risen since 1790. The government spent about a penny per person to count post-Revolutionary Americans. Today the census costs $ 250 million—more than a dollar per person. That's a long way since 3800 B. C.

单选题 Passage Two (1) Since the lineage of investigative journalism is most directly traceable to the progressive era of the early 1900's, it is not surprising that the President of the United States at the time was among the first to articulate its political dimensions. Theodore Roosevelt called investigative reporters "muckrakers," after a character from John Bunyan's Pilgrim's Progress who humbly cleaned "the filth off the floor." Despite the misgivings implied by the comparison, Roosevelt saw the muckrakers as "often indispensable to the well-being of society". (2) There are in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man, whether politician or businessman. (3) Roosevelt recognized the value-laden character of investigative journalism. He perceived correctly that investigative reporters are committed to unearthing wrongdoing. For these journalists, disclosures of morally outrageous conduct maximize the opportunity for the forces of "good" to recognize and do battle with the forces of "evil". (4) So, the current folklore surrounding investigative reporting closely resembles the American ideal of popular democracy. Partly a product of its muckraking roots, this idealized perspective is also an outgrowth of the commonly perceived effects of exposes published in the early 1970's. The most celebrated of these exposes were the news stories that linked top White House officials to Watergate crimes. These stories were widely held responsible for the public's loss of confidence in the Nixon administration, ultimately forcing the President's resignation.

单选题To understand the marketing concept, it is only necessary to understand the difference between marketing and selling. Not too many years ago, most industries concentrated primarily on the efficient production of goods, and then relied on "persuasive salesmanship" to move as much of these goods as possible. Such production and selling focuses on the needs of the seller to produce goods and then convert them into money. Marketing, on the other hand, focuses on the wants of consumers. It begins with first analyzing the preferences and demands of consumers and then producing goods that will satisfy them. This eye-on-the-consumer approach is known as the marketing concept, which simply means that instead of trying to sell whatever is easiest to produce or buy for resale, the makers and dealers first try to find out what the consumer wants to buy and then go about making it according to consumer demand. This concept does not imply that consumer satisfaction is given priority over profit in a company. There are always two sides to every business activity—the firm and the customer—and each must be satisfied before trade occurs. Successful merchants and producers, however, recognize that the surest route to profit is through understanding customers. This concept has been recognized in such slogans as "Have It Your Way. " and "You're the Boss. " A good example of the importance of satisfying the consumer presented itself in mid 1985, when Coca-Cola changed the flavor of its drink. The non-acceptance of the new flavor by a significant portion of the public brought about a prompt restoration of the Classic Coke, which was then marketed alongside the new. King Customer ruled!
