1、大学英语六级考试试题（1999 年 1 月）Part I Reading Comprehension Questions 01-05 are based on the following passage: In managing information resources, the medium may be the key to an effective system. The medium is a vehicle, a tool, or a container for holding information; the information itself is the thing of
2、value. Three popular categories of information media are paper, film, and electronic storage devices The media choice must not be viewed as a choice among these three, however; it must be viewed a s an opportunity to select from a multitude of media possibilities in combinations that build effective
3、 systems. In many instances the person responsible for information-resource management is not the person who determines the medium in which information will be created. In such a case, the manager of a firms information resources faces a challenge in making a significant contribution to the organiza
4、tions objectives. For effective management of information resources, media conversion may be necessary. Examples include keying or scanning paper documents to convert them to electronic media. Other processes convert electronic media from one format to another. For example, disk files created on one
5、 system may not be compatible with another system. Various hardware and software combinations can be used to convert files to formats that equipment will accept. For information generated within organizations, this necessity of making systems compatible may be eliminated by cooperative planning. How
6、ever, very little control can be exercised over the media used to generate information that comes to your organization from the outside. The medium for information may be selected to satisfy a need that exists when information is created and communicated. For example, a paper record may be created b
7、ecause of its portability and because no special equipment is necessary for later references to that information; electronic transmission may be selected because it is the fastest means of communicating information. A firm may use electronic mail because a network already exists for on-line computer
8、 communication. The additional application may cost less than postage to mail paper memos. 01. Which of the following can best sum up the passage? A. Media Selection in Managing Information Resources. B. The Importance and Necessity of Media Conversion. C. Three Categories of Information Media. D. V
9、arious Means of Communicating Information 02. The first paragraph aims at telling the reader _. A. the importance of information resources management B. the relationship between the medium and information C. the great variety of media for holding information D. the numerous resources of information
10、03. According to the author, _. A. paper is the best storage device B. people have three choices in selecting information media C. it is better to let the person responsible for information-resource management determine the medium D. the manager should build an effective system by selecting a good c
11、ombination of different media 04. For effective management of information resources, the manager should _. A. convert all paper documents to electronic media B. make media conversion when necessary C. control the media used to generate information both inside and outside his organization D. use one
12、format in processing information 05. The main idea of the last paragraph is _. A. paper record is the most convenient medium for later reference B. electronic mail costs less than postage to mail paper memos C. different media for information may be selected for different purposes D. by using differ
13、ent media, a firm can create various information for its objectives Questions 06-10 are based on the following passage: Many leading scientists down through the years form Galieo to Einstein have been deeply religious. They have been intrigued by the essential mystery of life and material existence,
14、 and have recognized that spiritual as well as scientific understanding is needed. Two biologists might examine a living cell under a microscope. One will see there the handiwork of God; the other will see only what evolution has chanced to produce. And yet both will agree on the cells biological hi
15、story, its composition, its structure, and its function. One physicist will find God in the exquisitely organized and exact laws of the physical universe. Another physicist will not be able to see anything beyond the laws themselves. The religious views of a scientist do not come from his science; t
16、hey come from his entire philosophy, his whole view of the world. But scientists are not unique in this matter; the same disparity of thinking is to be found among people from all walks of life. In the modern world, science serves two important functions. One is to provide the basis for a scientific
17、 technology. It is in this way that science has the greatest influence on our daily living. Through technology, we advance the structure of civilization and gain increasing domination over the earth and adjoining portions of the universe. The other purpose served by science is one of understanding.
18、Through science, we discover how phenomena occur and, to a limited extent, why they happen the way they do. Vital processes are analysed and studied, that we may know more of how organisms function, and how they have come to be what they are. Through science, we seek to know that a man is - how his
19、body works and why he thinks and dreams. As we search to know ourselves and the workings of our minds, we expect to find solutions to problems of confusion and discontent. Science is a way to understanding, but in some ways it is a narrow path that does not touch on all the questions posed by the fa
20、cts of human life. Science does not provide a way of life; it does not create a moral order. It is quite obvious that not all human knowledge can be reduced to scientific terms. Interpretations of the ultimate meaning and value of life will, in the final analysis, be made more on the basis of spirit
21、ual awareness than on scientific acuity. 06. According to the author, many leading scientists _. A. have acknowledged that only religion can explain the mystery of life B. have been puzzled by the mystery of life and material things C. have attempted to explain physical life from a religious point o
22、f view D. have engaged in intrigue trying to solve the mystery of life 07. The author suggests in the second paragraph that _. A. while some physicists conclude from the laws of nature that there is a God, others draw no such conclusion B. it is only by studying philosophy that a man can develop rel
23、igious beliefs C. by examining a living cell under a microscope biologists can understand the process of evolution D. there is a disparity of thinking between scientists and people from other walks of life regarding science and religion 08. In the last sentence of the second paragraph, “this matter“
24、 refers to _. A. the fact that a scientists religious views derive from his whole outlook on life B. the fact that some people believe in God while others do not C. the disparity of thinking between scientists and people from other walks of life D. the disparity in the religious conclusions drawn fr
25、om the observation of natural phenomena 09. In the third paragraph “scientific technology“ is _. A. the application of scientific knowledge to the skills of industry B. the application of science and industry to daily life C. science and industry as the basis of progress D. the use of science and in
26、dustrial techniques in gaining control of the universe 10. In the third paragraph it is mentioned that by means of science _ are analyzed and studied. A. the ways in which cells formed B. changes in organic life C. the main ways in which organisms develop D. processes on which organic life depends Q
27、uestions 11-15 are based on the following passage: Joseph Weizenbaum, professor of computer science at MIT, thinks that the sense of power over the machine ultimately corrupts the computer hacker and makes him into a not very-desirable sort of programmer. The hackers are so involved with designing t
28、heir program, making it more and more complex and bending it to their will, that they dont bother trying to make it understandable to other users. They rarely keep records of their programs for the benefit of others, and they take rarely time to understand why a problem occurred. Computer science te
29、achers say they can usually pick out the prospective hackers in their courses because these students make their homework assignments more complex than they need to be. Rather than using the simplest and most direct method, they take joy in adding extra steps just to prove their ingenuity. But perhap
30、s those hackers know something that we dont about the shape of things to come. “That hacker who had to be literally dragged off his chair at MIT is now a multimillionaire of the computer industry,“ says MIT professor Michael Dertouzos. “And two former hackers became the founders of the highly succes
31、sful Apple home computer company.“ When seen in this light, the hacker phenomenon may not be so strange after all. If, as many psychiatrists say, play is really the basis for all human activity, then the hacker games are really the preparation for future developments. Sherry Turkle, a professor of s
32、ociology at MIT, has for years been studying the way computers fit into peoples lives. She points out that the computer, because it seems to us to be so “intelligent,“ so “capable,“ so.“human“ affects the way we think about ourselves and our ideas about what we are. She says that computers and compu
33、ter toys already play an important role in childrens efforts to develop an identity by allowing them to test ideas about what is alive and what is not. “The youngsters can form as many subtle nuances and textured relationships with the computers as they can with people.“Turke points out. 11. The pas
34、sage tells about _. A. the strange behaviour of the computer hackers B. the ultimate importance of bringing up computer hackers C. the different opinions concerning the hacker phenomenon D. what has caused the emergence of computer hackers 12. According to Prof. Weizenbaum, what led to the hackers s
35、trange behaviour is _. A. their strong desire to control the computer B. their ignorance of the responsibility of a programmer C. their incompetence in making new computer programmers D. their deliberate attempts to make their programs complex and impracticable 13. In Prof. Dertozos opinion, which o
36、f the following is TRUE?A. Computer industry will certainly make multimillionaires of the hackers. B. The hackers are likely to be very successful business men C. The hackers probably have better insight into the future than other people. D. Only a few hackers will be successful in their later life.
37、 14. We can guess from context clues that the phrase “to develop an identity“ (Para. 5) means _. A. to become distinguished B. to seek an answer C. to build up a creative ability D. to form a habit 15. The passage tries to convey to its readers the idea that _. A. perhaps the hacker phenomenon is no
38、t bad at all B. though the hackers are in fact playing with the computer, there may be some benefits C. the computer hackers are the hope of the computer industry of tomorrow D. the computer hackers could be useful if under proper guidance Questions 16-20 are based on the following passage: As one w
39、orks with color in a practical or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile changeable thing depending to a large extent on the relationship of the color to other colors seen simultaneously. It is not fixed in its relation to the direct stimulus
40、which creates it. On the other hand, the properties of surfaces that give rise to color do not seem to change greatly under a wide variety of illumination colors, usually looking much the same in artificial light as in daylight. Both of these effects seem to be due in large part to the mechanism of
41、color adaptation mentioned earlier. When the eye is fixed on a colored area, there is an immediate readjustment of the sensitivity of the eye to color in and around the area viewed. This readjustment does not immediately affect the color seen but usually does affect the next area to which the gaze i
42、s shifted. The longer the time of viewing, the higher the intensity, and the larger the area, the greater the effect will be in terms of its persistence in the succeeding viewing situation. As indicated by the work of Wright and Schouten, it appears that, at least for a first approximation, full ada
43、ptation takes place over a very brief time if the adapting source is moderately bright and the eye has been in relative darkness just previously. As the stimulus is allowed to act, however, the effect becomes more persistent in the sense that it takes the eye longer to regain its sensitivity to lowe
44、r intensities. The net result is that, if the eye is so exposed and then the gaze is transferred to an area of lower intensity, the loss of sensitivity produced by the first area will still be present and appear as an “afterimage“ superimposed on the second. The effect not only is present over the a
45、ctual area causing the “local adaptation“ but also spreads with decreasing strength to adjoining areas of the eye to produce “lateral adaptation.“ Also, because of the persistence of the effect if the eye is shifted around from one object to another, all of which are at similar brightness or have si
46、milar colors, the adaptation will tend to become uniform over the whole eye. 16. This selection is concerned primarily with _. A. the adaptation of the eye to color B. the color of colors C. the properties of colored surfaces D. the effect of changes in color intensity 17. Whether a colored object w
47、ould, on two viewings separated in time, appear to the viewer as similar or different would depend mostly on _. A. the color mechanism of the eye in use at the time of each viewing B. what kind of viewing had immediately preceded each of the viewings C. the properties of the surfaces viewed D. the i
48、ndividuals power of lateral adaptation 18. If a persons eye has been looking at an object in bright sunlight for some time, and then shifts to an object not well lit - such as a lawn or shrub in shadow - we can expect _. A. a time lag in the focusing ability of the eye B. some inability to see color
49、s of the latter-named objects until loss of sensitivity has been regained C. the immediate loss of the “afterimage“ of the first object D. adaptation in the central area of the eye but little adaptation in the lateral areas to the new intensity level 19. The present selection has apparently been preceded by some explanation of _. A. some experiments with color pigments B. the nature of color C. the color properties of various surfaces D. the mechanism of the eyes adaptation to color 20. This selection tells us all the followin
