8、three times. When the passage is read for the first time, you should listen carefully for its general idea. Then listen to the passage again. When the passage is read for the second time, you are required to fill in the blanks numbered from S1 to S7 with the exact works you have just heard. For blan

9、ks numbered from S8 to S10 you are required to fill in the missing information. You can either use the exact works you have just heard or write down the main points in your own words. Finally, when the passage is read for the third time, you should check what you have written.In police work, you can

10、 never predict the next crime or problem. No working day is identical to any other, so there is no “(S1) _” day for a police officer. Some days are (S2) _ slow, and the job is (S3) _; other days are so busy that there is no time to eat. I think I can (S4) _ police work in one word: (S5) _. Sometimes

11、 its dangerous. One day, for example, I was working undercover; that is, I was on the job, but I was wearing (S6) _ clothes, not my police (S7) _. I was trying to catch some robbers who were stealing money from people as they walked down the street. Suddenly, (S8) _. Another policeman arrived, and t

12、ogether, we arrested three of the men; but the other four ran away. Another day, I helped a woman who was going to have a baby. (S9) _. I put her in my police car to get her there faster. I thought she was going to have the baby right there in my car. But fortunately, (S10) _.Part II Reading Compreh

13、ension (35 minutes)Directions:There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a si

14、ngle line through the center.Passage OneQuestions 11 to 15 are based on the following passage.The fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label: “store in the refrigerator.”In my fridgeless Fifties childhood, I was fed well and heal

15、thy. The milkman came daily, the grocer, the butcher (肉商), the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus (剩余的) bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirt

16、y years on, food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well-tried techniques already existed-natural cooling, drying, smoking, salting, sugaring, bott

17、ling.What refrigeration did promote was marketingmarketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the globe in search of a good price.Consequently, most of the worlds fridges are to be found, not in the tropics where they might prove useful, but in t

18、he wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house-while outside, nature provides the desired tem

19、perature free of charge.The fridges effect upon the environment has been evident, while its contribution to human happiness has been insignificant. If you dont believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers (漢堡包), but at least

20、youll get rid of that terrible hum.11.The statement “In my fridgeless Fifties childhood, I was fed well and healthily.” (Line 1, Para. 2) suggests that _.A) the author was well-fed and healthy even without a fridge in his fiftiesB) the author was not accustomed to using fridges even in his fiftiesC)

21、 there was no fridge in the authors home in the 1950sD) the fridge was in its early stage of development in the 1950s（C）12.Why does the author say that nothing was wasted before the invention of fridges?A) People would not buy more food than was necessary.B) Food was delivered to people two or three

22、 times a week.C) Food was sold fresh and did not get rotten easily.D) People had effective ways to preserve their food.（D）13.Who benefited the least from fridges according to the author?A) Inventors.B) Consumers.C) Manufacturers.D) Traveling salesmen.（B）14.Which of the following phrases in the fifth

23、 paragraph indicates the fridges negative effect on the environment?A) “Hum away continuously”.B) “Climatically almost unnecessary”.C) “Artificially-cooled space”.D) “With mild temperatures”.（A）15.What is the authors overall attitude toward fridges?A) Neutral.B) Critical.C) Objective.D) Compromising

24、.（B）Passage TwoQuestions 16 to 20 are based on the following passage.The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability,

25、but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the rig

26、ht software (軟件) or by altering the architecture but that too will happen.I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they wil

27、l be able to reproduce themselves. Silicon will have ended carbons long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale

28、we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the cons

29、truction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.16.In what way can we make a machine intelligent?A) By making it work in such environments as deserts, oceans or space.B) By working hard for 10 or 20 years.C) By either properly program

30、ming it or changing its structure.D) By reproducing it.（C）17.What does the writer think about machines with human-like ability?A) He believes they will be useful to human beings.B) He believes that they will control us in the future.C) He is not quite sure in what way they may influence us.D) He doe

31、snt consider the construction of such machines possible.（A）18.The word “carbon” (Line 4, Para. 2) stands for _.A) intelligent robotsB) a chemical elementC) an organic substanceD) human beings（D）19.A robot can be used to expand our frontiers when _.A) its intelligence and cost are beyond questionB) i

32、t is able to bear the rough environmentC) it is made as complex as the human brainD) its architecture is different from that of the present ones（A）20.It can be inferred from the passage that _.A) after the installation of a great number of cells and connections, robots will be capable of self-reprod

33、uctionB) with the rapid development of technology, people have come to realize the possibility of making a machine with human-like abilityC) once we make a machine as complex as the human brain, it will posses intelligenceD) robots will have control of the vast, man-made world in space（B）Passage Thr

34、eeQuestions 21 to 25 are based on the following passage.After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll (死亡人數(shù)) could have been much worse.More than 60 people died in this earthquake. By comparison, as earthquake of

35、 similar intensity that shook America in 1988 claimed 25,000 victims.Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the citys highways. In addition, changes made to the construction codes in Los Angeles during t

36、he last 20 years have strengthened the citys buildings and highways, making them more resistant to quakes.Despite the good new, civil engineers arent resting on their successes. Pinned to their drawing boards are blueprints (藍(lán)圖) for improved quake-resistant buildings. The new designs should offer ev

37、en greater security to cities where earthquakes often take place.In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the bu

38、ilding and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquakes vibrations. When the ground shakes and the building tips f

39、orward, the computer would force the building to shift in the opposite direction.The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.21.One reason why the loss of lives in the Los Angeles earthquake

40、was comparatively low is that _.A) new computers had been installed in the buildingsB) it occurred in the residential areas rather than on the highwaysC) large numbers of Los Angeles residents had gone for a holidayD) improvements had been made in the construction of buildings and highways（D）22.The

41、function of the computer mentioned in the passage is to _.A) counterbalance an earthquakes action on the buildingB) predict the coming of an earthquake with accuracyC) help strengthen the foundation of the buildingD) measure the impact of an earthquakes vibrations（A）23.The smart buildings discussed

42、in the passage _.A) would cause serious financial problemsB) would be worthwhile though costlyC) would increase the complexity of architectural designD) can reduce the ground vibrations caused by earthquakes（B）24.It can be inferred from the passage that in minimizing the damage caused by earthquakes

43、 attention should be focused on _.A) the increasing use of rubber and steel in capital constructionB) the development of flexible building materialsC) the reduction of the impact of ground vibrationsD) early forecasts of earthquakes（C）25.The authors main purpose in writing the passage is to _.A) com

44、pare the consequences of the earthquakes that occurred in the U.S.B) encourage civil engineers to make more extensive use of computersC) outline the history of the development of quake-resistant building materialsD) report new developments in constructing quake-resistant buildings（D）Passage FourQues

45、tions 26 to 30 are based on the following passage.Even plants can run a fever, especially when theyre under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adapting the infrared (紅外線) scanning technology develop

46、ed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (殺蟲劑) spraying rather than rain poison on a whole field, which invariably

47、includes plants that dont have pest (害蟲) problems.Even better, Paleys Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed

48、into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.The bad news is that Paleys company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers

49、 were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States,” sa

50、ys George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.26.Plants will emit an increased

51、amount of heat when they are _.A) sprayed with pesticidesB) facing an infrared scannerC) in poor physical conditionD) exposed to excessive sun rays（C）27.In order to apply pesticide spraying precisely, we can use infrared scanning to _.A) estimate the damage to the cropsB) draw a color-coded mapC) me

52、asure the size of the affected areaD) locate the problem area（D）28.Farmers can save a considerable amount of pesticide by _.A) resorting to spot-sprayingB) consulting infrared scanning expertsC) transforming poisoned rainD) detecting crop problems at an early date（A）29.The application of infrared sc

53、anning technology to agriculture met with some difficulties due to _.A) the lack of official supportB) its high costC) the lack of financial supportD) its failure to help increase production（C）30.Infrared scanning technology may be brought back into operation because of _.A) the desire of farmers to

54、 improve the quality of their produceB) growing concern about the excessive use of pesticides on cropsC) the forceful promotion by the Department of AgricultureD) full support from agricultural experts（B）Part III Vocabulary and Structure (20 minutes)Directions:There are 30 incomplete sentences in th
