42、g Comprehension(40 minutes)Section ADirections ： 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 fallowing the passage. Read the passage through carefully before making your choices. Each choice in th

43、e 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 possibilit

44、y of a double 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 drinking and 27 driving. At the same time, they provide state and local governments with billions of dollars of

45、revenue. Tobacco taxes, which generate more than twice as much, have proven 28 in the decline of smoking, which has saved millions of lives.6 4Taxes can also be an important tool fbr environmental protection, and many economists say taxing carbon would be the best way to reduce greenhouse gas emissi

46、ons. Economic theory says that unlike income or sales taxes, carbon taxes can actually increase economic efficiency; because companies that 29 carbon dioxide into the sky dont pay the costs of the climate change they cause, carbon taxes would restore the proper 30 to the market.In reality, carbon ta

47、xes alone wont be enough to halt global warming, but they would be a useful part of any climate plan. Whafs more, the revenue from this tax, which would 31 be hundreds of billions of dollars per year, could be handed out to citizens as a 32 or used to fund green infrastructure projects.Similarly, a

48、wealth tax has been put forward as a way to reduce inequality while raising revenue. The revenue from this tax, which some experts 33 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 i

49、nequality is 34 bad, then these taxes improve society while also 35 government coffers (金庫).discouragingdividendemotionalfragmentsimpaireddiscouragingdividendemotionalfragmentsimpairedimprisonedincentivesinherentlyinitiallyinstrumentalmergingpredictprobablypumpswellingDirections ： In this section, y

50、ou 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 questio

51、ns by marking the corresponding letter on Answer Sheet 2.The Challenges for Artificial Intelligence in AgricultureA group of com farmers stands huddled around an agronomist (農(nóng)學(xué)家)and his computer on the side of an irrigation machine in central South Africa. The agronomist has just flown over the fiel

52、d 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.The UAV is fitted with a four spectral band precision sensor that conducts onboard processing immediately aft

53、er the flight, allowing farmers and field staif to address, almost immediately, any crop abnormalities that the sensor may have recorded, making the data collection truly real-time.In this instance, the farmers and agronomist are looking to specialized software to give them an accurate plant populat

54、ion count. Its been 10 days since the com 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.At this growth stage of the planfs development

55、, 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 f

56、uture practices for the season to come.The software completes its processing in under 15 minutes producing a plant population count map. Ifs 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 sam

57、e 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 w

58、ill produce a near accurate result.As the map appears on the screen, the agronomisfs 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

59、 is not correct, and so do the farmers, even with their limited understanding of how to read remote sensing maps.Hypothetically, it is possible for machines to leam to solve any problem on earth relating to the physical interaction of all things within a defined or contained environment by using art

60、ificial intelligence and machine learning.Remote sensors enable algorithms (算法)to interpret a fields 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 st
