1、2005年同济大学考博英语真题试卷及答案与解析 一、 Reading Comprehension 0 As one works 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 colores seen simultaneou
2、sly. It is not fixed in its relation to the direct stimulus 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 (but not always) looking much the same in artificial light as in dayl
3、ight. Both of these effects seem to the due in large part to the mechanism of 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 a
4、ffect the color seen but usually does affect the next area to which the gaze is 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 Wrig
5、ht and Schouten, it appears that, at least for a first approximation, full adaptation 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 persist
6、ent in the sense that it takes the eye longer to regain its sensitivity to lower 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 “af
7、terimage“ super imposed on the second. The effect not only is present over the actual 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 arou
8、nd from one object to another, all of which are at similar brightnesses or have similar colors, the adaptation will tend to become uniform over the whole eye. 1 This selection is concerned primarily with _. ( A) the eyes adaptation to color ( B) the properties of colored surfaces ( C) the effect of
9、changes in color intensity ( D) experiments on colored objects 2 Whether a colored object would, on two viewings separated in time, appear to the viewer as similar or different in color would depend mostly on _. ( A) the color mechanism of the eye in use at the time of each viewing ( B) what kind of
10、 viewing had immediately preceded each of the viewings ( C) the properties of the surface being viewed ( D) whether the object was seen in artificial or natural light 3 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
11、a lawn or shrub in shadow-we can expect ( A) a time lag in the focusing ability of the eye ( B) the immediate loss of the “afterimage“ of the first object ( C) some inability to see colors of the latter-named objects until loss of sensitivity has been regained ( D) adaptation in the central area of
12、the eye but little adaptation in the lateral areas to the new intensity level 4 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 eyes ada
13、ptation to color 4 In the opinion of many Americans and Europeans, we only began to really explore our world in the sixteenth century. According to them, the sailors of the ancient world did not explore distant parts of the world; they did not have the necessary knowledge or skills for long sea jour
14、neys. However, the people who have this opinion are forgetting two important facts of history. First, sometimes early scientists have an idea which is correct, but scientists in later centuries do not believe it. For example, about 270 B. C., a Greek scientist had an idea which we all believe today:
15、 The earth moves around the sun. But for the following 1,600 years scientists did not believe this. In their opinion, the sun clearly moved around the earth. They discovered the truth again only in the fifteenth century! The second fact of history that many people forget is this: Ancient does not me
16、an primitive. For example, the ancient Egyptians knew a great deal about the stars; they used this knowledge to find their way across the oceans. Two thousand years ago a Greek scientist who lived in Egypt calculated the distance around the earth. The results of his calculations were close to the re
17、al distance we know today! So the ancients had a great deal of scientific knowledge. They also had skills which equaled the skills of to- day. For example, 1,300 years ago and before, fishermen in Ireland built their boats of wood and leather. Today some fishermen in Ireland still make boats of the
18、same de- sign. They use tools and materials which are not very different from the tools and materitals which their ancestors used. Why? The ancient design of the boats was good, and with skillful sailors, these boats can sail in all kinds of weather. Clearly long before the sixteenth century, people
19、 had the skill, the knowledge and the equipment which were necessary for long journeys by sea. The world did not have to wait until the sixteenth century for its first explorers! 5 Which of the following statements is consistent with the passage? ( A) According to the writer, we only began to really
20、 explore the world in the sixteenth century. ( B) In the history of science, people sometimes have to discover a fact a second time. ( C) The ancient Egyptians had very little knowledge about the stars. ( D) The writer agrees with many Americans and Europeans except for the two facts mentioned in th
21、e passage. 6 Why does the writer use the example of the Greek scientist who calculated the distance around the world? ( A) He wants to show the primitive knowledge of ancient scientists. ( B) He wants to give an example of something which later scientists did not believe. ( C) He wants to give an ex
22、ample of scientific knowledge which was available to early explorers. ( D) He wants to show that science has not been developing significantly. 7 According to the writer, why do Irish fishermen still use boats like the boats which their ancestors used 1,000 years ago? ( A) Boats made of wood or leat
23、her are light and fast. ( B) The necessary materials are easily available. ( C) They dont have the money for expensive boats. ( D) The design of the boats is very good. 8 “People from the ancient world sailed around Africa. They even reached America.“ In your opinion, how would the writer of the pas
24、sage feel about these ideas? ( A) He has used this as an important fact to praise ancient civilization. ( B) He does not believe them. ( C) In his opinion, ancient explorers did not have the skills necessary for long journeys. ( D) In his opinion, they are possible. 8 I can think of no better career
