7、ments. For each of them, there are four choices marked A, B, C, and D. Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center. 11 The climate of Earth is changing. Climatologists are confident that over the past century, the global average surface temperat
8、ure has increased by about half a degree Celsius. This warming is thought to be at least partly the result of human activities, such as the burning of fossil fuels and the clearing of forests for agriculture. As the global population grows and national economies expand, the global average temperatur
9、e is expected to continue increasing by an additional 1.0 to 3.5 by the year 2100. Climate change is one of the most important environmental issues facing humankind. Understanding the potential impacts of climate change for natural ecosystems is essential if we are going to manage our environment to
10、 minimize the negative consequences of climate change and maximize the opportunities that it may offer. Because natural ecosystems are complex, nonlinear systems, it follows that their responses to climate change are likely to be complex. Climate change may affect natural ecosystems in a variety of
11、ways. In the short term, climate change can alter the mix of plant species in land ecosystems such as grasslands. In the long term, climate change has the potential to dramatically alter the geographic distribution of major vegetation types savannas, forests, and climate change can also potentially
12、alter global ecosystem processes, including the cycling of carbon, nitrogen, phosphorus, and sulfur. Moreover, changes in these ecosystem processes can affect and be affected by changes in the plant species of the ecosystem and vegetation type. All of the climate change induced alterations of natura
13、l ecosystems affect the services that these ecosystems provide to humans. The global average surface temperature increase of half a degree. Celsius observed over the past century has been in part due to differential changes in daily maximum and minimum temperatures, resulting in a narrowing of the d
14、iurnal temperature range. Decreases in the diurnal temperature range were first identified in the United States, where large-area trends showed that maximum temperatures have remained constant or increased only slightly, whereas minimum temperatures have increased at a faster rate. In this issue, Al
15、ward et al report on the different sensitivities of rangeland plants to minimum temperatures increases. 11 Which of the following is NOT mentioned as a reason for the global warming? （ A） The burning of fuels such as coal or oil. （ B） The clearing of forests. （ C） The cultivation of farmland. （ D） T
16、he negative consequences of human activities. 12 The second paragraph is primarily concerned with_. （ A） the potential impacts of climate change for natural ecosystems （ B） how to minimize the negative consequences of climate change （ C） how to maximize the opportunities that climate change may offe
17、r （ D） the complex, nonlinear nature of natural ecosystems 13 According to the author, what may chiefly be responsible for the temperature increases observed over the past century? （ A） Increases of daily maximum temperatures. （ B） Decreases of daily minimum temperatures. （ C） Increases of diurnal t
18、emperature range. （ D） Decreases in the diurnal temperature range. 14 In subsequent paragraphs, we may expect the writer of this passage to_. （ A） discuss the global impacts of temperatures increases （ B） present a point of view which supports the idea of the second paragraph （ C） introduce Alwards
19、report on the different sensitivities of rangeland plants to minimum temperatures increases （ D） further illustrate the causes of the global average surface temperature increases 15 The word “diurnal“(Line 3, Para 3) is closest in meaning to_. （ A） day-and-nights （ B） everyday （ C） two days （ D） yea
20、rly 16 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 tha
21、t a technologist thinks about cant 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
22、 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 technologists mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress
23、 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 suppli
24、ed 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 a
25、n 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 pr
26、imitive 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
27、 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-solvi
28、ng, 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. Abs
29、urd 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. 16 In the passage, the author is primarily concerned with_. （ A） identifying the kinds of thi
30、nking 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 17 It can be infe
31、rred that the author thinks engineering curricula are_. （ A） strengthened when they include courses in design （ B） strong because nonverbal thinking is still emphasized by most of the course （ C） strong despite the errors that graduates of such curricula have made in the development of automatic con
32、trol systems （ D） strong despite the absence of nonscientific modes of thinking 18 The main point of the first two paragraphs can best be illustrated as_. （ A） when a machine like a rotary engine malfunctions, it is the technologist who is best equipped to repair it （ B） a telephone is a complex ins
33、trument designed by technologists using only nonverbal thought （ C） the designer of a new refrigerator should consider the designs of other refrigerators before deciding on its form （ D） the distinctive features of a suspension bridge reflect its designers conceptualization as well as the physical r
34、equirements of its site 19 The example of the early models of high-speed railroad cars is used to_. （ A） weaken the point that math is a necessary part of the study of design （ B） support the idea that errors in modem engineering systems are likely to increase （ C） illustrate the topic that courses
35、in design are the most effective cost-reducing means （ D） exemplify the thesis that inadequate attention to nonscientific design may result in poor design 20 The author seems to be in agreement of which of the following? （ A） Mathematical thinking is essential to any design course. （ B） Non-verbal t
36、hinking has its advantage over other perceptive processes. （ C） Engineering design demands scientific thought. （ D） Artists play a primitive role in engineering work. 21 We all know that the normal human daily cycle of activity is of some 748 hours sleep alternating with some 16,417 hours wakefulnes
37、s and that, broadly speaking, the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at
38、 night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is
39、 often the case in industry that shifts are changed every week: a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p. m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of
40、 his time is spent neither working nor sleeping very efficiently. The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night shift workers was carried out by Brown in 1957. She found a high i
41、ncidence of disturbed sleep find other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work. This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the str
42、ains of alternate day and night work by selecting those people who can adapt most quickly to the Changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People engaged in normal day-time work will have a high temperature during the hours of wakefulness
43、and a low one at night; when they change to night work the pattern will only adjust gradually back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperat
44、ure at intervals of two hours throughout the period of wakefulness it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far; however, such a form of selection does not seem to have been applied in practice. 21 Why is the question of
45、 “how easily people can get used to working at flight“ no mere academic one? （ A） Because few people like to reverse the cycle of sleep and wakefulness. （ B） Because sleep normally coincides with the hours of darkness. （ C） Because people are required to work at night in some fields of industry. （ D
46、） Because shift work in industry requires people to change their sleeping habits. 22 The main problem of the round-the-clock working system lies in_. （ A） the inconveniences brought about to, the workers by the introduction of automation （ B） the disturbance of the daily cycle of workers who have to
47、 change shifts too frequently （ C） the fact that people working at night are often less effective （ D） the fact that it is difficult to find a number of good night workers 23 It is possible to find out if a person has adapted to the changes of routine by measuring his body temperature because_. （ A）
48、 body temperature changes when the cycle of sleep and wakefulness alternates （ B） body temperature changes when he changes to night shift or back （ C） the temperature reverses when the routine is changed （ D） people have higher temperatures when they are working efficiently 24 Which of the following
49、 statements is NOT tree? （ A） Body temperature may serve as an indication of a workers performance. （ B） The selection of a number of permanent night shift workers has proved to be the best solution to problems of the round-the-clock working system. （ C） Taking body temperature at regular intervals can show how a person adapts to the changes of routine. （ D） Disturbed sleep occurs less frequently among those on permanent night or day shifts. 25 It is implied in the last paragraph that
