Many objects in daily use have clearly been influenced by science, but their form. and function, their dimensions and appearances 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 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

One of the qualities that most people admire in others is the willingness to admit one's mistakes. (79) It is extremely hard some times to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that."
I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a grocery store in the neighborhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and I began to remember vaguely the incident he was de scribing.
I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular clay, I must have found my way to the dairy food department where the incident tool place.
(80) There must have been a special sale on eggs that day be cause there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together; so I went to work.
The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was culprit(罪犯). He severely scolded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not.
How old was the author when he wrote this article?
A.About 8.
B.About 18.

Where did the movies begin? It is often said that they are an American invention. It is not entirely true. The motion picture has been the most international arts. Before the dawn of the twentieth century, inventors in France, England and the United States were among the dozens of men who were trying to develop ways of using photographs to create the effect of motion. Soon after 1889, when the famous inventor Thomas Edison first showed motion pictures through a device called the kinetoscope(活动电影放映机), other devices for the same purpose appeared all over the world. Edison had solved certain problems, making it possible for other inventors move ahead with their own devices. One other important contribution by Edison was the introduction of 35 mm as the international standard film width.
That the movies are an American invention is not entirely true. This means that______.
A.it is entirely wrong
B.to some degree, it is true
C.it is not true at all
D.it is perfectly right

A patent is an exclusive right given to an inventor for his or her invention. In other words, a patent is a monopoly right given to the inventor for the invention. A patent confers on the inventor the right to price and to sell the invention in any way he or she desires, in the United States, patents are granted by the Patent Office for 17 years. Although economists generally condemn monopoly as a form. of market organization since monopoly imposes costs on the economy, patents present a more subtle case for monopoly theory. Specifically, can patent monopolies be justified?
In general, economists complain about the costs of monopoly because they believe that the same industry could be organized competitively. A patent monopoly grant for 17 years presents a different problem. That is, the purpose of the patent system is to encourage invention. The issue is not monopoly versus competition but, more fundamentally, invention versus no invention. Is the world better off with the invention, even though it is monopolized for 17 years? In other words, what are the costs and benefits of a patent?
Consider the simple case of a new consumer product with a positive demand, such as a camera utilizing a new exposure process. The costs of the patent monopoly are simply the deadweight costs of monopoly measured by the lost consumers' surplus from the 17-year patent monopoly. This cost must be assessed carefully in the context of an invention, however. What are the benefits of the patent system? First, there is the increase in consumer well-being brought about immediately by a desirable invention. In 17 years, the patent monopoly ends, and a second source of benefits arises: The price of cameras will fall to a competitive level, and consumers will reap the benefits of the camera at a lower price. In sum, theory of monopoly helps us to assess the costs and benefits of the patent. One can quibble about patent monopolies, arguing, for example, that they are granted for too long a time.
In the end, the patent system creates goods and services and technologies that did not previously exist. In this respect it is a valuable System for the economy. The patent system also underscores the importance of property rights to ideas as a source of economic growth and progress.
The first paragraph mainly______.
A.focuses on business monopoly
B.tells us about the patent system in America
C.discusses a special form. of market organization
