G. H. Hardy, a famous Cambridge University mathematician received a letter from an Indian named Srinivasa Ramanujan asking him for his opinion of 120 mathematical theorems (定理) that Ramanujan said he had discovered. To Hardy, many of the theorems made no sense. Of the others, one or two were already well-known. Ramanujan must be some kind of trickplayer, Hardy decided, and put the letter aside. But all that day the letter kept hanging round Hardy. Might there be something in those wild-looking theorems?That evening Hardy invited another brilliant Cambridge mathematician, J. E. Littlewood, and the two men set out to assess the Indian’s worth. That incident was a turning point in the history of mathematics.At the time, Ramanujan was an obscure Madras Port Trust clerk. A little more than a year later, he was at Cambridge University, and beginning to be recognized as one of the most amazing mathematicians the world has ever known. Though he died in 1920, much of his work was so far in advance of his time that only in recent years is it beginning to be properly understood.Indeed, his results are helping solve today’s problems in computer science and physics, problems that he could have had no notion of.For Indians, moreover, Ramanujan has a special significance. Ramanujan, though born in poor and ill-paid accountant’s family 100 years ago, has inspired many Indians to adopt mathematics as career.Much of Ramanujan’s work is in num ber theory, a branch of mathematics that deals with the subtle (难以捉摸的) laws and relationships that govern numbers. Mathematicians describe his results as elegant and beautiful but they are much too complex to be appreciated by laymen.His life, though, is full of drama and sorrow. It is one of the great romantic stories of mathematics, a distressing reminder that genius can surface and rise in the most unpromising circumstances.21. When Hardy received the 120 theorems from Ramanujan, his attitude at first mightbe best described as ________.A) uninterestedB) unsympatheticC) suspiciousD) curious22. Ramanujan’s position in Cambridge University owed much to ________.A) the judgement of his work by Hardy and LittlewoodB) his letter of application accepted by HardyC) his work as a clerk at Madras Port TrustD) his being recognized by the world as a famous mathematician23. It may be inferred from the passage that the author ________.A) feels sorry for Ramanujan’s early deathB) is dissatisfied with the slow development of computer scienceC) is puzzled about the complexity of Ramanujan’s theo remsD) greatly appreciates Ramanujan’s mathematical genius24. In the last paragraph, the author points out that ________.A) Ramanujan’s mathematical theorems were not appreciated by othermathematiciansB) extremely talented people can prove their worth despite difficult circumstancesC) Ramanujan also wrote a number of stories about mathematicsD) Ramanujan had worked out an elegant but complicated method of solvingproblems25. The word “laymen” (Last Para, Lind 6) most probably means ________.A) people who do not specialize in mathematical scienceB) people who are carelessC) people who are not interested in mathematicsD) people who don’t like to solve complicated problemsPassage TwoQuestions 26 to 30 are based on the following passage.Even if all the technical and intellectual problems can be solved, there are major social problems inherent in the computer revolution. The most obvious is unemployment, since the basic purpose of commercial computerization is to get more work done by fewer people. OneBritish study predicts that “automation induced unemployment” in Western Europe could reach16~, 6 in the next decade, but most analyses are more optimistic. The general rule seems to be that new technology eventually creates as many jobs as it destroys, and often more. “People who put in computers usually increase their staffs as well” says CPT’s Scheff. “Of course,” he adds, “one industry may kill another industry. That’s tough onsome people.”Theoretically, all unemployed workers can be retrained, but retraining programs are not high on the nation’s agenda (议事日程). Many new jobs, moreover, will require an ability in using computers, and the retraining needed to use them will have to be repeated as the technology keeps improving. Says a chilling report by the Congressional Office of Technology Assessment:“Lifelong retraining is expected to become the standard for many people. “There is a already considerable evidence that the school children now being educated in the use of computers are generally the children of the white middle class. Young blacks, whose unemployment rate stands today at 50 96, will find another barrier in front of them.Such social problems are not the fault of the computer, of course, but a consequence of the way the American society might use the computer. “Even in the days of the Big, main-frame computers, when they were a machine for the few.” says Katherine Davis Fishman, author ofThe Computer Establishment, “it was a tool to help the rich get richer. It still is to a large extent. One of the great values of the personal computer is that smaller firms, smaller organizations can now have some of the advantages of the bigger organizations.”26. The closest restatement of “one industry may kill another industry” (Para. 1 Line 11)is that ________.A) industries tend to compete with one anotherB) one industry might be driven out of business by another industryC) one industry may increase its staff at the expense of anotherD) industries tend to combine into bigger ones27. The word “chilling” (Para. 2, Line 5) most probably means ________.A) misleadingB) convincingC) discouragingD) interesting28. Which of the following is NOT mentioned in the passage?A) Computers are efficient in retraining unemployed workers.B) Computers may offer more working opportunities than they destroy.C) Computers will increase the unemployment rate of young blacks.D) Computers can help smaller organizations to function more effectively.29. From the passage it can be inferred that ________.A) all school children are offered a course in the use of computersB) all unemployed workers are being retrainedC) retraining programmes are considered very important by the governmentD) in reality only a certain portion of unemployed workers will be retrained30. The major problem discussed in the passage is ________.A) the importance of lifelong retraining of the unemployed workersB) the social consequences of the widespread use of computers in the United StatesC) the barrier to the employment of young peopleD) the general rule of the advancement of technologyPassage ThreeQuestions 31 to 35 are based on the following passage.Mobility of individual members and family groups tends to split up family relationships.Occasionally the movement of a family away from a situation which has been the source of friction results in greater family organization, but on the whole mobility is disorganizing.Individuals and families are involved in three types of mobility: movement in space, movement up or down in social status, and the movement of ideas. These are termed respectively spatial, vertical, and ideational mobility.A great increase in spatial mobility has gone along with improvements in rail and water transportation, the invention and use of the automobile, and the availability of airplane passenger service. Spatial mobility results in a decline in the importance of the traditional home with its emphasis on family continuity and stability. It also means that when individual family members or the family as a whole move away from a community, the person or the family is removed from the pressures of relatives, friends, and community institutions for conventionality and stability. Even more important is the fact that spatial mobility permits some members of a family to come in contact with and possibly adopt attitudes, values, and ways of thinking different from those held by other family members. The presence of different attitudes, values, and ways of thinking with in a family may, and often does, result in conflict and family disorganization. Potential disorganization is present in those families in which the husband, wife, and children are spatially separated over a long period, or are living together but see each other only briefly because of different work schedules.One index of the increase in vertical mobility is the great increase in the proportion of sons, and to some extent daughters, who engage in occupations other than those of the parents.Another index of vertical mobility is the degree of intermarriage between racial classes. This occurs almost exclusively between classes which are adjacent to each other. Engaging in a different occupation, or intermarriage, like spatial mobility, allows one to come in contact with ways of behavior different from those of the parental home, andtends to separate parents and their children.The increase in ideational mobility is measured by the increase in publications, such as newspapers, periodicals, and books, the increase in the percentage of the population owning radios, and the increase in television sets. All these tend to introduce new ideas into the home.When individual family members are exposed to and adopt the new ideas, the tendency is for conflict to arise and for those in conflict to become psychologically separated from each other.31. What the passage tells us can be summarized by the statement:A) social development results in a decline in the importance of traditional familiesB) potential disorganization is present in the American familyC) family disorganization is more or less the result of mobilityD) the movement of a family is one of the factors in raising its social status32. According to the passage, those who live in a traditional family ________.A) are less likely to quarrel with others because of conventionality and stabilityB) have to depend on their relatives and friends if they do not move away from itC) can get more help from their family members if they are in troubleD) will have more freedom of action and thought if they move away from it33. Potential disorganization exists in those families in which ________.A) the husband, wife, and children work too hardB) the husband, wife, and children seldom get togetherC) both parents have to work full timeD) the family members are subject to social pressures34. Intermarriage and different occupations play an important role in familydisorganization because ________.A) they enable the children to travel around without their parents’ permissionB) they allow one to find a good job and improve one’s social statusC) they enable the children to better understand the ways of behavior of theirparentsD) they permit one to come into contact with different ways of behavior andthinking35. This passage suggests that a well-organized family is a family whose members________.A) are not psychologically withdrawn from one anotherB) never quarrel with each other even when they disagreeC) often help each other with true love and affectionD) are exposed to the same new ideas introduced by books, radios, and TV sets Passage FourQuestions 36 to 40 are based on the following passage.To call someone bird-brained in English means you think that person is silly or stupid.But will this description soon disappear from use in the light of recent research? It seems the English may have been unfair in association bird’s brains with stupidity.In an attempt to find out how different creatures see the world, psychologists at Brown University in the USA have been comparing the behaviour of birds and humans. One experiment has involved teaching pigeons to recognize letters of the English alphabet. The birds study in “classrooms”, which are boxes equipped with a computer. After about four days of studying a particular letter, the pigeon has to pick out that letter from several displayed on the computer screen. Three male pigeons have learnt to distinguish all twenty-six letters of the alphabet in this way.A computer record of the birds’ four-month study period has shown surprising similarities between the pigeons’ and human performance. Pigeons and people find the same letters easy, or hard, to tell apart. For example, 92 per cent of the time the pigeons could tell the letter D from the letter Z. But when faced with U and V (often confused by English children), the pigeons were right only 34 per cent of the time.The results of the experiments so far have led psychologists to conclude that pigeons and humans observe things in similar ways. This suggests that there is something fundamental about the recognition process. If scientists could only discover just what this recognition process is it could be very useful for computer designers. The disadvantage of a present computer is that it can only do what a human being has programmed it to do and the programmer must give the computer precise, logical instructions. Maybe in the future, though, computers will be able to think like human beings.36. The writer suggests that the expression “bird-brained” might be out of use soonbecause it is ________.A) sillyB) impoliteC) unnecessaryD) inappropriate37. Psychologists have been experimenting with pigeons to find out whether the birds________.A) are really silly or stupidB) can learn to make ideas known to peopleC) see the world as human beings doD) learn more quickly than children38. U and V are confused by ________.A) 92 per cent of pigeonsB) many English childrenC) most people learning EnglishD) 34 per cent of English children39.

You may not use any of the words in the bank more than once.Questions 36 to 45 are based on the following passage.According to a report from the Harvard School of Public Health, many everyday products, including some bug sprays and cleaning fluids, could lead to an increased risk of brain and behavioral disorders in children. The developing brain, the report says, is particularly (36) to the toxic effects of certain chemicals these products may contain, and the damage they cause can be(37) .The official policy, however, is still evolving. Health and environmental(38) have long urged U.S. government agencies to (39) the use of some of the 11 chemicals the report cites and called for more studies on their long-term effects. In 2001, for example, the Environmental Protection Agency (40) the type and amount of lead that could be present in paint and soil in homes and child-care(41), after concerns were raised about lead poisoning. The agency is now (42) the toxic effects of some of the chemicals in the latest report.But the threshold for regulation is high. Because children's brain and behavioral disorders, like hyperactivity and lower grades, can also be linked to social and genetic factors, it's tough to pin them on exposure to specific chemicals with solid(43)evidence, which is what the EPA requires. Even the Harvard study did not prove a direct (44) but noted strong associations between exposure and risk of behavioral issues.Nonetheless, it's smart to (45) caution.

Each paragraph is marked with a letter.Answer the questions by marking the correspondingletter on Answer Sheet 2.The Impossibility of Rapid Energy Transitions[ A ] Politicians are fond of promising rapid energy transitions. Whether it is a transition from imported to domestic oil or from coal-powered electricity production to natural-gas power plants, politicians love to talk big. Unfortunately for them (and often the taxpayers), our energy systems are a bit like an aircraft carrier: they are unbelievably expensive, they are built to last for a very long time, they have a huge amount of inertia ( meaning it takes a lot of energy to set them moving ), and they have a lot of momentum once they are set in motion. No matter how hard you try, you can't turn something that large on a dime ( 10美分硬币 ), or even a few thousand dimes.[ B ] In physics, moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia and momentum. Inertia is the resistance of objects to efforts to change their state of motion. If you try to push a boulder ( 大圆石 ), it pushes you back. Once you have started the boulder rolling, it develops momentum, which is defined by its mass and velocity.Momentum is said to be "conserved," that is, once you build it up, it has to go somewhere. So a heavy object, like a football player moving at a high speed, has a lot of momentum-that is, once he is moving, it is hard to change his state of motion. If you want to change his course, you have only a few choices: you can stop him, transferring ( possibly painfully) some of his kinetic energy (动能) to your own body, or you can approach alongside and slowly apply pressure to gradually alter his course.[ C ] But there are other kinds of momentum as well. After all, we don't speak only of objects or people as having momentum;we speak of entire systems having momentum. Whether it's a sports team or a presidential campaign, everybody relishes having the big momentum, because it makes them harder to stop or change direction.[ D ] One kind of momentum is technological momentum. When a technology is deployed, its impacts reach far beyond itself. Consider the incandescent (白炽灯的) bulb, an object currently hated by many environmentalists and energy-efficiency advocates. The incandescent light bulb, invented by Thomas Edison, which came to be the symbol of inspiration, has been developed into hundreds, if not thousands, of forms. Today, a visit to a lighting store reveals a stunning array of choices. There are standard-shaped bulbs, flame-shaped bulbs, colored globe-shaped bulbs, and more. It is quite easy, with all that choice, to change a light bulb.[ E ] But the momentum of incandescent lighting does not stop there. All of those specialized bulbs ledto the building of specialized light fixtures, from the desk lamp you study by, to the ugly but beloved hand-painted Chinese lamp you inherited from your grandmother, to the ceiling fixture in your closet, to the light in your oven or refrigerator, and to the light that the dentist points at you. It is easy to change a light bulb, sure, but it is harder to change the bulb and its fixture.[ F ] And there is more to the story, because not only are the devices that house incandescent bulbs shaped to their underlying characteristics, but rooms and entire buildings have been designed in accordance with how incandescent lighting reflects off walls and windows.[ G ] As lighting expert Howard Brandston points out, “ Generally, there are no bad light sources, only bad applicati ons." There are some very commendable characteristics of the CFL [ compact fluorescent (荧光的) light bulb ], yet the selection of any light source remains inseparable from the luminaire (照明装置) that houses it, along with the space in which both are installed, and lighting requirements that need to be satisfied. The lamp, the fixture, and the room, all three must work in concert for the true benefits of end-users. If the CFL should be used for lighting a particular space, or an object within that space, the fixture must be designed to work with that lamp, and that fixture with the room. It is a symbiotic (共生的) relationship. A CFL cannot be simply installed in an incandescent fixture and then expected to produce a visual appearance that is more than washed out, foggy, and dim. The whole fixture must be replaced-light source and luminaire-and this is never an inexpensive proposition.[ H ] And Brandston knows a thing or two about lighting, being the man who illuminated the Statue of Liberty.[ I ]Another type of momentum we have to think about when planning for changes in our energy systems is labor-pool momentum. It is one thing to say that we are going to shift 30 percent of our electricity supply from, say, coal to nuclear power in 20 years. But it is another thing to have a supply of trained talent that could let you carry out this promise. That is because the engineers,designers, regulators, operators, and all of the other skilled people needed for the new energy industry are specialists who have to be trained first ( or retrained, if they are the ones being laid off in some related industry), and education, like any other complicated endeavor, takes time.And not only do our prospective new energy workers have to be trained, they have to be trained in the right sequence. One needs thedesigners, and perhaps the regulators, before the builders and operators, and each group of workers in training has to know there is work waiting beyond graduation. In some cases, colleges and universities might have to change their training programs, adding another layer of difficulty.[ J ] By far the biggest type of momentum that comes into play when it comes to changing our energy systems is economic momentum. The major components of our energy systems, such as fuel production, refining, electrical generation and distribution, are costly installations that have lengthy life spans. They have to operate for long periods of time before the costs of development have been recovered. When investors put up money to build, say, a nuclear power plant, they expect to earn that money back over the planned life of the plant, which is typically between 40and 60 years. Some coal power plants in the United States have operated for more than 70 years!The oldest continuously operated commercial hydro-electric plant in the United States is on New York's Hudson River, and it went into commercial service in 1898.[ K ] As Vaclav Smil points out, "All the forecasts, plans, and anticipations cited above have failed so miserably because their authors and promoters thought the transitions they hoped to implement would proceed unlike all previous energy transitions, and that their progress could be accelerated in an unprecedented manner. "[ L ] When you hear people speaking of making a rapid transition toward any type of energy, whether it is a switch from coal to nuclear power, or a switch from gasoline-powered cars to electric cars, or even a switch.from an incandescent to a fluorescent light, understanding energy system inertia andmomentum can help you decide whether their plans are feasible.46. Not only moving objects and people but all systems have momentum.47. Changing the current energy system requires the systematic training of professionals and skilled labor.48. Changing a light bulb is easier than changing the fixture housing it.49. Efforts to accelerate the current energy transitions didn't succeed as expected.50. To change the light source is costly because you have to change the whole fixture.51. Energy systems, like an aircraft carrier set in motion, have huge momentum.52. The problem with lighting, if it arises, often doesn't lie in light sources but in their applications.53. The biggest obstacle to energy transition is that the present energy system is too expensive to replace.54. The application of a technology can impact areas beyond itself.55. Physical characteristics of moving objects help explain the dynamics of energy systems.下载文档。

Each choice in the bank is identified by a letter Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.The idea of taxing things that are bad for society has a powerful allure. It offers the possibility of a double benefit— 27 harmful activities, while also providing the government with revenue.Take sin taxes. Taxes on alcohol make it more expensive to get drunk, which reduces excessive drinking and 28 driving. At the same time, they provide state and local governments with billions of dollars of revenue. Tobacco taxes, which generate more than twice as much, have proven 29 in the decline of smoking, which has saved millions of lives.Taxes can also be an important tool for environmental protection, and many economists say taxing carbon would be the best way to reduce greenhouse gas emissions. Economic theory says that unlike income or sales taxes, carbon taxes can actually increase economic efficiency; because companies that 30 carbon dioxide into the sky don't pay the costs of the climate change they cause, carbon taxes would restore the proper 31 to the market.In reality, carbon taxes alone won't be enough to halt global warming, but they would be a useful part of any climate plan. What's more, the revenue from this tax, which would 32 be hundreds of billions of dollars per year, could be handed out to citizens as a 33 or used to fund green infrastructure projects.Similarly, a wealth tax has been put forward as a way to reduce inequality while raising revenue. The revenue from this tax, which some experts 34 will be over $4 trillion per decade, would be designated for housing, child care, health care and other government benefits. If you believe, as many do, that wealth inequality is 35 bad, then these taxes improve society whilealso 36 government coffers (金库).A. discouragingB. dividendC. emotionalD. fragmentsE. impairedF. imprisonedG. incentivesH. inherentlyI. initiallyJ. instrumentalK. mergingL. predictM. probablyN. pumpO. swellingSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter Answer the questions by marking the corresponding letter on Answer Sheet 2. The Challenges for Artificial Intelligence in AgricultureA. A group of corn farmers stands huddled around an agronomist (学家) and his computer on the side of an irrigation machine in central South Africa. The agronomist has just flown over the field with a hybrid unmanned aerial vehicle (UAV) that takes off and lands using propellers yet maintains distance and speed for scanning vast hectares of land through the use of its fixed wings.B. The UAV is fitted with a four spectral band precision sensor that conducts on board processing immediately after the flight, allowing farmers and field staff to address, almost immediately, any crop abnormalities that the sensor may have recorded, making the data collection truly real-time.C. In this instance, the farmers and agronomist are looking to specialized software to give them an accurate plant population count. It's been 10 days since the corn emerged and the farmer wants to determine if there are any parts of the field that require replanting due to a lack of emergence or wind damage, which can be severe in the early stages of the summer rainy season.D. At this growth stage of the plant's development, the farmer has another 10 days to conduct any replanting before the majority of his fertilizer and chemical applications need to occur. Once these have been applied, it becomes economically unviable to take corrective action, making any further collected data historical and useful only to inform future practices for the season to come.E. The software completes its processing in under 15 minutes producing a plant population count map. It's difficult to grasp just how impressive this is, without understanding that just over a year ago it would have taken three to five days to process the exact same data set, illustrating the advancements that have been achieved in precision agriculture and remote sensing in recent years. With the software having been developed in the United States on the same variety of crops in seemingly similar conditions, the agronomist feels confident that the software will produce a near accurate result.F. As the map appears on the screen, the agronomist's face begins to drop. Having walked through the planted rows before the flight to gain a physical understanding of the situation on the ground, he knows the instant he sees the data on his screen that the plant count is not correct, and so do the farmers, even with their limited understanding of how to read remote sensing maps.G. Hypothetically, it is possible for machines to learn to solve any problem on earth relating to the physical interaction of all things within a defined or contained environment by using artificial intelligence and machine learning.H. Remote sensors enable algorithms (算法) to interpret a field's environment as statistical data that can be understood and useful to farmers for decision-making. Algorithms process the data, adapting and learning based on the data received. The more inputs and statistical information collected, the better the algorithm will be at predicting a range of outcomes. And the aim is that farmers can use this artificial intelligence to achieve their goal of a better harvest through making better decisions in the field.I. In 2011, IBM, through its R&D Headquarters in Haifa, Israel, launched an agriculturalcloud-computing project. The project, in collaboration with a number of specialized IT andagricultural partners, had one goal in mind—to take a variety of academic and physical data sources from an agricultural environment and turn these into automatic predictive solutions for farmers that would assist them in making real-time decisions in the field.J. Interviews with some of the IBM project team members at the time revealed that the team believed it was entirely possible to "algorithm" agriculture, meaning that algorithms could solve any problem in the world. Earlier that year, IBM's cognitive learning system, Watson, competed in the game Jeopardy against former winners Brad Rutter and Ken Jennings with astonishing results. Several years later, Watson went on to produce ground-breaking achievements in the field of medicine.K. So why did the project have such success in medicine but not agriculture? Because it is one of the most difficult fields to contain for the purpose of statistical quantification. Even within a single field, conditions are always changing from one section to the next. There's unpredictable weather, changes in soil quality, and the ever-present possibility that pests and disease may pay a visit. Growers may feel their prospects are good for an upcoming harvest, but until that day arrives, the outcome will always be uncertain.L. By comparison, our bodies are a contained environment. Agriculture takes place in nature, among ecosystems of interacting organisms and activity, and crop production takes place within that ecosystem environment. But these ecosystems are not contained. They are subject to climatic occurrences such as weather systems, which impact upon hemispheres as a whole, and from continent to continent. Therefore, understanding how to manage an agricultural environment means taking literally many hundreds if not thousands of factors into account.M. What may occur with the same seed and fertilizer program in the United States' Midwest region is almost certainly unrelated to what may occur with the same seed and fertilizer program in Australia or South Africa. A few factors that could impact on variation would typically include the measurement of rain per unit of a crop planted, soil type, patterns of soil degradation, daylight hours, temperature and so forth.N. So the problem with deploying machine learning and artificial intelligence in agriculture is not that scientists lack the capacity to develop programs and protocols to begin to address the biggest of growers' concerns; the problem is that in most cases, no two environments will be exactly alike, which makes the testing, validation and successful rollout of such technologies much more laborious than in most other industries.O. Practically, to say that AI and Machine Learning can be developed to solve all problems related to our physical environment is to basically say that we have a complete understanding of all aspects of the interaction of physical or material activity on the planet. After all, it is only through our understanding of 'the nature of things' that protocols and processes are designed for the rational capabilities of cognitive systems to take place. And, although AI and Machine Learning are teaching us many things about how to understand our environment, we are still far from being able to predict critical outcomes in fields like agriculture purely through the cognitive ability of machines.P. Backed by the venture capital community, which is now investing billions of dollars into the sector, most agricultural technology startups today are pushed to complete development as quickly as possible and then encouraged to flood the market as quickly as possible with their products.Q. This usually results in a failure of a product, which leads to skepticism from the market and delivers a blow to the integrity of Machine Learning technology. In most cases, the problem is not that the technology does not work, the problem is that industry has not taken the time to respect that agriculture is one of the most uncontained environments to manage. For technology to truly make an impact on agriculture, more effort, skills, and funding is needed to test these technologies in farmers' fields.R. There is huge potential for artificial intelligence and machine learning to revolutionize agriculture by integrating these technologies into critical markets on a global scale. Only then can it make a difference to the grower, where it really counts.37、Farmers will not profit from replanting once they have applied most of the fertilizer and other chemicals to their fields.38、Agriculture differs from the medical science of the human body in that its environment is not a contained one.39、The agronomist is sure that he will obtain a near accurate count of plant population with hissoftware.40、The application of artificial intelligence to agriculture is much more challenging than to most other industries.41、Even the farmers know the data provided by the UAV is not correct.42、The pressure for quick results leads to product failure, which, in turn, arouses doubts about the applicability, of AI technology to agriculture.43、Remote sensors are aimed to help farmers improve decision-making to increase yields.44、The farmer expects the software to tell him whether he will have to replant any parts of his farm fields.45、Agriculture proves very difficult to quantify because of the constantly changing conditions involved.46、The same seed and fertilizer program may yield completely different outcomes in different places.Section CDirections: There are 2 passages in this section. 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 Answer Sheet 2 with a single line through the centre.Passage OneWhat is the place of art in a culture of inattention'? Recent visitors to the Louvre report that tourists can now spend only a minute in front of the Mona Lisa before being asked to move on. Much of that time, for some of them, is spent taking photographs not even of the painting but of themselves with the painting in the background.One view is that we have democratised tourism and gallery-going so much that we have made it effectively impossible to appreciate what we've travelled to see. In this oversubscribed society, experience becomes a commodity like any other. There are queues to climb Mt. Jolmo Lungma as well as to see famous paintings. Leisure, thus conceived, is hard labour, and returning to work becomes a well-earned break from the ordeal.What gets lost in this industrialised haste is the quality of looking. Consider an extreme example, the late philosopher Richard Wollheim. When he visited the Louvre he could spent as much as four hours sitting before a painting. The first hour, he claimed, was necessary for misperceptions to be eliminated. It was only then that the picture would begin to disclose itself. This seems unthinkable today, but it is still possible to organise. Even in the busiest museums there are many rooms and many pictures worth hours of contemplation which the crowds largely ignore. Sometimes the largest crowds are partly the products of bad management; the Mona Lisa is such a hurried experience today partly because the museum is being reorganised. The Uffizi in Florence, another site of cultural pilgrimage, has cut its entry queues down to seven minutes by clever management. And there are some forms of art, those designed to be spectacles as well as objects of contemplation, which can work perfectly well in the face of huge crowds.Olafur Eliasson's current Tate Modern show, for instance, might seem nothing more than an entertainment, overrun as it is with kids romping (喧闹地玩耍) in fog rooms and spray mist installations. But it's more than that: where Eliasson is at his most entertaining, he is at his most serious too, and his disorienting installations bring home the reality of the destructive effects we are having on the planet—not least what we are doing to the glaciers of Eliasson's beloved Iceland.Marcel Proust, another lover of the Louvre, wrote: "It is only through art that we can escape from ourselves and know how another person sees the universe, whose landscapes would otherwise have remained as unknown as any on the moon." If any art remains worth seeing, it must lead us to such escapes. But a minute in front of a painting in a hurried crowd won't do that.47、What does the scene at the Louvre demonstrate according to the author? ______A. The enormous appeal of a great piece of artistic work to tourists.B. The near impossibility of appreciating art in an age of mass tourism.C. The ever-growing commercial value of long-cherished artistic works.D. The real difficulty in getting a glimpse at a masterpiece amid a crowd.48、Why did the late philosopher Richard Wollheim spend four hours before a picture? ______A. It takes time to appreciate a piece of art fully.B. It is quite common to misinterpret artistic works.C. The longer people contemplate a picture, the more likely they will enjoy it.D. The more time one spends before a painting, the more valuable one finds it.49、What does the case of the Uffizi in Florence show? ______A. Art works in museums should be better taken care of.B. Sites of cultural pilgrimage are always flooded with visitors.C. Good management is key to handling large crowds of visitors.D. Large crowds of visitors cause management problems for museums.50、What do we learn from Olafur Eliasson's current Tate Modern show? ______A. Children learn to appreciate art works most effectively while they are playing.B. It is possible to combine entertainment with appreciation of serious art.C. Art works about the environment appeal most to young children.D. Some forms of art can accommodate huge crowds of visitors.51、What can art do according to Marcel Proust? ______A. Enable us to live a much fuller life.B. Allow us to escape the harsh reality.C. Help us to see the world from a different perspective.D. Urge us to explore the unknown domain of the universe.Passage TwoEvery five years, the government tries to tell Americans what to put in their bellies. Eat more vegetables. Dial back the fats. It's all based on the best available science for leading a healthy life. But the best available science also has a lot to say about what those food choices do to the environment, and some researchers are annoyed that new dietary recommendations of the USDA (United States Department of Agriculture) released yesterday seem to utterly ignore that fact.Broadly, the 2016-2020 dietary recommendations aim for balance: More vegetables, leaner meats and far less sugar.But Americans consume more calories per capita than almost any other country in the world. So the things Americans eat have a huge impact on climate change. Soil tilling releases carbon dioxide, and delivery vehicles emit exhaust. The government's dietary guidelines could have done a lot to lower that climate cost. Not just because of their position of authority: The guidelines drive billions of dollars of food production through federal programs like school lunches and nutrition assistance for the needy.On its own, plant and animal agriculture contributes 9 percent of all the country's greenhouse gas emissions. That's not counting the fuel burned in transportation, processing, refrigeration, and other waypoints between farm and belly. Red meats are among the biggest and most notorious emitters, but trucking a salad from California to Minnesota in January also carries a significant burden. And greenhouse gas emissions aren't the whole story. Food production is the largest user of fresh water, largest contributor to the loss of biodiversity, and a major contributor to using up natural resources.All of these points and more showed up in the Dietary Guidelines Advisory Committee's scientific report, released last February. Miriam Nelson chaired the subcommittee in charge of sustainability for the report, and is disappointed that eating less meat and buying local food aren't in the final product. "Especially if you consider that eating less meat, especially red and processed, has health benefits," she says.So what happened? The official response is that sustainability falls too far outside the guidelines' official scope, which is to provide "nutritional and dietary information."Possibly the agencies in charge of drafting the decisions are too close to the industries they are supposed to regulate. On one hand, the USDA is compiling dietary advice. On the other, their clients are US agriculture companies.The line about keeping the guidelines' scope to nutrition and diet doesn't ring quite right with researchers. David Wallinga, for example, says, "In previous guidelines, they've always beenconcerned with things like food security—which is presumably the mission of the USDA. You absolutely need to be worried about climate impacts and future sustainability if you want secure food in the future."52、Why are some researchers irritated at the USDA's 2016-2020 Dietary Guidelines? ______A. It ignores the harmful effect of red meat and processed food on health.B. Too much emphasis is given to eating less meat and buying local food.C. The dietary recommendations are not based on medical science.D. It takes no notice of the potential impact on the environment.53、Why does the author say the USDA could have contributed a lot to lowering the climate cost through its dietary guidelines? ______A. It has the capacity and the financial resources to do so.B. Its researchers have already submitted relevant proposals.C. Its agencies in charge of drafting the guidelines have the expertise.D. It can raise students' environmental awareness through its programs.54、What do we learn from the Dietary Guidelines Advisory Committee's scientific report? ______A. Food is easily contaminated from farm to belly.B. Greenhouse effect is an issue still under debate.C. Modem agriculture has increased food diversity.D. Fanning consumes most of our natural resources.55、What may account for the neglect of sustainability in the USDA's Dietary Guidelines according to the author? ______A. Its exclusive concern with Americans' food safety.B. Its sole responsibility for providing dietary advice.C. Its close ties with the agriculture companies.D. Its alleged failure to regulate the industries.56、What should the USDA do to achieve food security according to David Wallinga? ______A. Give top priority to things like nutrition and food security.B. Endeavor to ensure the sustainable development of agriculture.C. Fulfill its mission by closely cooperating with the industries.D. Study the long-term impact of climate change on food production.Part Ⅳ TranslationDirections: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.
