  GRE阅读真题精炼内容节选:

  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 non-scientific modes of thought. Many features and qualities of the objects that a technologist thinks about cannot 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 non -verbal thinking, by and large, that has fixed the outlines and filled in the details of our material surroundings. Pyramids, cathedrals, 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 (diesel engine: n. 柴油机), a technologist might impress individual ways of nonverbal thinking on the machine b y continually using an intuitive sense of rightness and fitness. What would be the shape of the combustion

  chamber (combustion chamber: 燃烧室)? Where should the valves be placed? Should it have

  a long or short piston? Such questions have a range of answers t hat 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 o f 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

  (stock-in-trade: n.存货, 惯用手段) 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 abilitie s 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 encounter 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.

  21. In the passage, the author is pr imarily concerned with

  (A) identifying the kinds of thinking that are used by technologists

  (B) stressing the importance of nonverbal thinking in engineering design

  (C) proposing a new role for nonscientific thinking in the development of technology

  (D) contrasting the goals of engineers with those of technologists

  (E) criticizing engineering schools for emphasizing science in engineering curricula
