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 tightness and fitness. What would be the shape of the combustion chamber？ Where should be the valves played？ 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 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. In the passage, the author is primarily 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．criticizing engineering schools for emphasizing science in engineering curricula

For some fifty million years, despite all its eccentricities, the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tubefeet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of colors, ranging from black to reddish-brown to sand-color and white. One form. even has vivid purple tentacles. Usually the creatures are cucumber-shaped hence their name and because they are typically rock inhabitants, this shape, combined with flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents. Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become motionless and live at a low metabolic rate — feeding sparingly or not at all for long periods, so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in short time and would probably starve themselves out of existence. But the most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself when it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted. The passage mainly discusses A．the reason for the sea cucumber's name. B．what makes the sea cucumber unusual. C．how to identify the sea cucumber. D．places where the sea cucumber can be.

2. If man's mind cannot be turned into a logic-machine, neither can it function properly as a great emotional sponge, to be squeezed at will. All of us have known people who gush as a general response to life——who gush in seeing a sunset, who gush in reading a book, who gush in meeting a friend. They may seem to live by emotion alone, but their constant gushing is a disguise for absence of genuine feeling, a torrent rushing to fill a vacuum. It is not uncommon to find beneath the gush a cold, analytic mind that is astonishing in its meticulousness and ruthless in its calculation. Somewhere between machine and sponge lies the reality of the mind——a blend of reason and emotion, of actuality and imagination, of fact and feeling. 3. The entanglement is so complete, the mixture so thoroughly mixed, that it is probably impossible to achieve pure reason or pure reason or pure emotion, at least for any sustained period of time. 4. It is probably best to assume that all our reasoning is fused with our emotional commitments and beliefs, all our thoughts colored by feelings that lie deep within our psyches. Moreover, it is probably best to assume that this stream of emotion is not a poison, not even a taint, but is a positive life-source, a stream of psychic energy that animates and vitalizes our entire thought process. 5. The roots of reason are embedded in feelings——feelings that have formed and accumulated and developed over a lifetime of personality-shaping. These feelings are not for occasional using but are inescapable. To know what we think, we must know how we feel. It is feeling that shapes belief and forms opinion. It is feeling that directs the strategy of argument. It is our feelings, then, with which we must come to honorable terms.

Dr. Jorge Yunis of the University of Minnesota Medical School in Minneapolis has found that 70 percent of oncogenes, or cancer-causing genes, are located near inherited weak points on chromosomes(染色体). Varying from individual to individual, vulnerable to chemical carcinogens(致癌剂), X rays and other cancer-inducing agents. "If a chromosome snaps apart in the immediate vicinity of an oncogene," says Yunis, "normal genetic control mechanisms could break down and the stage would be set for the formation of cancer." Younis has shown that such a sequence occurs at the beginning of numerous leukemias (白血病), lymphomas(淋巴瘤) and some tumors of the lung, colon(结肠) and breast. Yunis and other investigators have found that petroleum-based products--notably pesticides and insecticides-damage specific sites on at least two of the 23 pairs of human chromosomes that carry genetic information. Similarly, tobacco smoke tends to attack a part of another chromosome. From paragraph 1, we know that some 40 genes involving in cancer are ______. () A．harmful to the human body B．necessary to the human body C．the elements that form. cancer D．useless to the human body

Public interest lawyers fill this need. Patricia, like other public interest lawyers, earns a salary much below what some lawyers can earn. Because she is willing to take less money, her clients have the help they need, even if they can pay nothing at all. Some clients need legal help because stores have cheated them with faulty merchandise. Others are in unsafe apartments, or are threatened with eviction (being driven) and have no place to go. Their cases are all called "civil" cases. Still others are accused of criminal acts, and seek those public interest lawyers who handle "criminal" cases. These are just a few of the many situations in which the men and women who are public interest lawyers serve to extend justice throughout society. "A lawyer friend of mine has devoted herself to the service of humanity" means______. A. she has tried to earn her living by providing service for human beings B. she has tried to provide service to people in need out of humane consideration C. she has tried to work for the cause of law at any cost D. she has devoted herself to the public relationship in spite of loss of income What is the difference between public interest lawyers and other lawyers？ A. They have had more highly specialized training. B. Their training is much cheaper. C. They may offer help to those who can't afford to pay. D. They work long, difficult hours for the money they earn. The word "clients" in this passage means______. A. people who can pay high fees to their lawyers B. people who are very poor and can't afford to pay their lawyers C. people who have been cheated by stores or threatened with eviction D. people who needs and uses legal help from lawyers Public interest law includes______. A. civil cases only B. criminal cases only C. criminal and civil cases D. wealthy clients cases Which of the following is not a matter for a civil case？ A. A tenant is faced with eviction. B. A burglar is arrested. C. A landlord refuses to fix a dangerous staircase. D. A store sells a faulty radio.
