Reading Comprehension

(40 minutes)

Section A

Directions:In this section,there is a passage with ten blanks.You are required to select one word for each

blank from a list of choices given in a word bank following the passage.Read the passagethrough carefully before making your choices.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 throughthe 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 adouble benefit-26 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 drinkingand 27 driving.At the same time,they provide state and local governments with billions of dollars ofrevenue.Tobacco taxes,which generate more than twice as much,have proven 28 in the decline ofsmoking,which has saved millions of lives.

Taxes can also be an important tool for environmental protection,and many economists say taxingcarbon would be the best way to reduce greenhouse gas emissions.Economic theory says that unlike incomeor sales taxes,carbon taxes can actually increase economic efficiency;because companies that 29 carbondioxide into the sky don't pay the costs of the climate change they cause,carbon taxes would restore theproper 30 to the market.

In reality,carbon taxes alone won't be enough to halt global warming,but they would be a useful partof any climate plan.What's more,the revenue from this tax,which would 31 be hundreds of billions ofdollars per year,could be handed out to citizens as a 32 or used to fund green infrastructure projects.

Similarly,a wealth tax has been put forward as a way to reduce inequality while raising revenue.Therevenue from this tax,which some experts 33 will be over $4 trillion per decade,would be designatedfor housing,child care,health care and other government benefits.If you believe,as many do,that wealthinequality is 34 bad,then these taxes improve society while also 35 government coffers().

A)discouraging

Section B

Directions: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 theinformation is derived.You may choose a paragraph more than once.Each paragraph is markedwith a letter.Answer the questions by marking the corresponding letter on Answer Sheet 2.

The Challenges for Artificial Intelligence in Agriculture

[A]A group of corn farmers stands huddled around an agronomist and his computer on the side ofan irrigation machine in central South Africa.The agronomist has just flown over the field with a hybridunmanned aerial vehicle (UAV)that takes off and lands using propellers yet maintains distance and speedfor scanning vast hectares of land through the use of its fixed wings.

2020年12月大学英语六级考试真题（第一套）第3页

B]The UAV is fitted with a four spectral band precision sensor that conducts onboard processing

immediately after the flight,allowing farmers and field staff to address,almost immediately,any cropabnormalities 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 ifthere are any parts of the field that require replanting due to a lack of emergence or wind damage,whichcan 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 replantingbefore the majority of his fertilizer and chemical applications need to occur.Once these have beenapplied,it becomes economically unviable to take corrective action,making any further collected datahistorical 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'sdifficult to grasp just how impressive this is,without understanding that just over a year ago it wouldhave taken three to five days to process the exact same data set,illustrating the advancements that havebeen achieved in precision agriculture and remote sensing in recent years.With the software havingbeen developed in the United States on the same variety of crops in seemingly similar conditions.theagronomist 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 knowsthe instant he sees the data on his screen that the plant count is not correct,and so do the farmers,evenwith 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 interactionof all things within a defined or contained environment by using artificial intelligence and machine learning.[H]Remote sensors enable algorithms to interpret a field's environment as statistical data that can beunderstood and useful to farmers for decision-making.Algorithms process the data,adapting and learningbased on the data received.The more inputs and statistical information collected,the better the algorithmwill be at predicting a range of outcomes.And the aim is that farmers can use this artificial intelligence toachieve 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 agricultural cloud-computingproject.The project,in collaboration with a number of specialized IT and agricultural partners,had onegoal in mind-to take a variety of academic and physical data sources from an agricultural environmentand turn these into automatic predictive solutions for farmers that would assist them in making real-timedecisions in the field.

[J]Interviews with some of the IBM project team members at the time revealed that the team believed itwas entirely possible to "algorithm"agriculture,meaning that algorithms could solve any problem inthe world.Earlier that year,IBM's cognitive learning system,Watson,competed in the game Jeopardyagainst 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 themost 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 insoil quality,and the ever-present possibility that pests and diseases may pay a visit.Growers may feel theirprospects 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,amongecosystems of interacting organisms and activity,and crop production takes place within that ecosystemenvironment.But these ecosystems are not contained.They are subject to climatic occurrences such asweather 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 notthousands of factors into account.

[M]What may occur with the same seed and fertilizer program in the United States'Midwest region is almostcertainly 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 perunit 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 scientistslack 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,

2020年12月大学英语六级考试真题（第一套）第4页

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 ourphysical environment is to basically say that we have a complete understanding of all aspects of theinteraction 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 cognitivesystems to take place.And,although AI and Machine Learning are teaching us many things about howto understand our environment,we are still far from being able to predict critical outcomes in fields likeagriculture purely through the cognitive ability of machines.

[P]Backed by the venture capital community,which is now investing billions of dollars in the sector,mostagricultural technology startups today are pushed to complete development as quickly as possible andthen 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 deliversa blow to the integrity of Machine Learning technology.In most cases,the problem is not that thetechnology does not work,the problem is that industry has not taken the time to respect that agricultureis one of the most uncontained environments to manage.For technology to truly make an impact onagriculture,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 byintegrating these technologies into critical markets on a global scale.Only then can it make a differenceto the grower,where it really counts.

36.Farmers will not profit from replanting once they have applied most of the fertilizer and other chemicalsto their fields.

37.Agriculture differs from the medical science of the human body in that its environment is not a contained one.

38.The agronomist is sure that he will obtain a near accurate count of plant population with his software.

39.The application of artificial intelligence to agriculture is much more challenging than to most other industries.

40.Even the farmers know the data provided by the UAV is not correct.

41.The pressure for quick results leads to product failure,which,in turn,arouses doubts about the applicability ofAI technology to agriculture.

42.Remote sensors are aimed to help farmers improve decision-making to increase yields.

43.The farmer expects the software to tell him whether he will have to replant any parts of his farm fields.

44.Agriculture proves very difficult to quantify because of the constantly changing conditions involved.

45.The same seed and fertilizer program may yield completely different outcomes in different places.

Section C

Directions: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 decideon the best choice and mark the corresponding letter on Answer Sheet 2 with a single linethrough the centre.

Passage One

Questions 46 to 50 are based on the following passage.

What is the place of art in a culture of inattention?Recent visitors to the Louvre report that tourists can nowspend 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 effectivelyimpossible to appreciate what we've travelled to see.In this oversubscribed society,experience becomes acommodity 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,thephilosopher Richard Wollheim.When he visited the Louvre he could spend as much as four hours sittingbefore a painting.The first hour,he claimed,was necessary for misperceptions to be eliminated.It was onlythen that the picture would begin to disclose itself.This seems unthinkable today,but it is still possible toorganise.Even in the busiest museums there are many rooms and many pictures worth hours of contemplationwhich the crowds largely ignore.Sometimes the largest crowds are partly the products of bad management;

2020年12月大学英语六级考试真题（第一套）第5页

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 byclever management.And there are some forms of art.these designed to be spectacles as well as objects ofcontemplation,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 anentertainment,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 hisdisorienting installations bring home the reality of the destructive effects we are having on the planet-notleast what we are doing to the glaciers of Eliasson's belowed Iceland.

Marcel Proust,another lover of the Louvre,wrote:"It is only through art that we can escape fromourselves and know how another person sees the universe,whose landscapes would otherwise have remainedas unknown as any on the noon.If any art remains worth seeing,it must lead us to such escapes.But aminute in front of a painting in a hurried crowd won't do that.

46.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

47.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.

48.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.

49.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.

50.What can art do according to Marcel Proust?

A)Enable us to live a much fuller life.

C)Help us to see the world from a different perspective.

B)Allow us to escape the harsh reality.

D)Urge us to explore the unknown domain of the universe.

Passage Two

Questions 51 to 55 are based on the following passage.

Every 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 availablescience also has a lot to say about what those food choices do to the environment,and some researchers areannoyed that new dietary recommendations of the USDA(United States Department of Agriculture)releasedyesterday seem to utterly ignore that fact.

Broadly,the 2016-2020 dietary recommendations aim for balance:More vegetables,leaner meats and farless sugar.

But Americans consume more calories per capita than almost any other country in the world.So thethings Americans eat have a huge impact on climate change.Soil tilling releases carbon dioxide,and deliveryvehicles 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 productionthrough 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 gasemissions.That's not counting the fuel burned in transportation,processing,refrigeration,and otherwaypoints between farm and belly.Red meats are among the biggest and most notorious emitters,but
