Part I[ 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 passage through 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 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

The Challenges for Artificial Intelligence in Agriculture
A) A group of com farmers stands huddled around an agronomist 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 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.
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 (■$-?£•) 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 inthe 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
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 Al 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 Al 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 in 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.
36. Farmers will not profit from replanting once they have applied most of the fertilizer and other
chemicals to their fields.
37. Agriculture differs from the medical science of the human body in that its environment is not a
contained one.
A&2020*pl2£ 538. 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 of Al 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) andD). You should decide on the
best choice and mark the corresponding letter on Answer Sheet 2 with a single line through 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 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 spend 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 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.
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.
2020 12 6C) 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 Modem 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.
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 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 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 balances 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, andi sdi sappointedtha teat ingless meat andbu ying localfo odare n’tin thefina lpr oduc t.“Es peciallyif
youconside rth ate atingless mea t,espec ially redan dprocessed ,has hea lthbenefits ,”sh esays.
2020^12^ 7So 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 been concerned
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. ”
51. 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.
52. 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.
53. 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) Modern agriculture has increased food diversity.
D) Farming consumes most of our natural resources.
54. 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.
55. 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.
