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— 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 revenue. Tobacco taxes, which generate more than twice as much, have proven 28 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 __29 _ carbon dioxide into the sky don’t pay the costs of the climate change they cause, carbon taxes would restore the proper 30 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 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 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 inequality is 34 bad, then these taxes improve society while also 35 government coffers (金库). 13 A) discouraging B) dividend C) emotional D) fragments E) impaired F) imprisoned G) incentives H) inherently I) initially J) instrumental K) merging L) predict M) probably N) pump O) swelling 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 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 Price of Oil and the Price of Carbon A) A group of corn farmers stands huddled around an agronomist (农学家)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 onboard 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 agricultural cloud-computing project. The project, in collaboration with a number of specialized IT and agricultural 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 diseases 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 li
