选词填空详解:
从题目所给选项来看，考察形容词和名词居多。注意有些选项中的词具有多个词性，比如feature一词，既可用作名词也可用作动词，这就要求考生在做题时要灵活思考，仔细区分。
在做题时，需要对空格所在句进行分析，同时结合题干的一些提示特征迅速对空格的词性做出判断。例如，“情态动词/助动词后接动词原形”、“不定式to后接动词原形”、“and/or并列结构前后对应”等等。此外，如果所填空格是动词，需要结合时态、语态对动词词尾的变化进行判断。
总的来说，考生掌握了单词释义并结合辅助的判断技巧，得出题目答案并非难事。
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 number of devices you can talk to is multiplying—first it was your phone, then your car, and now you can tell your kitchen appliance what to do. But even without gadgets that understand our spoken commands, research suggests that, as bizarre as it sounds, under certain 26, people regularly ascribe human traits to everyday objects.
Sometimes we see things as human because we are 27. In one experiment, people who reported feeling isolated were more likely than others to attribute 28 to various gadgets. In turn, feeling close to objects can 29 loneliness. When college students were reminded of a time they had been 30 in a social setting, they compensated by exaggerating their number of friends-unless they were first given tasks that caused them to interact with their phone as if it had human qualities. According to the researchers, the participants’ phones 31 substituted for real friends.
At other times, we personify products in an effort to understand them. One study found that three in four respondents yelled at their computer. Further, the more their computer gave them problems, the more likely the respondents were to report that it had its own “beliefs and 32.”
So how do people assign traits to an object? In part, we rely on looks. On humans, wide faces are 33 with dominance. Similarly, people rated cars, clocks, and watches with wide faces as more dominant-looking than narrow-faced ones, and preferred them-especially in 34 situations. An analysis of car sales in Germany found that cars with grilles(护栅)that were up turned like smiles sold best. The purchasers saw this 35 as increasing a car’s friendliness.
A) alleviate
B) apparently
C) arrogant
D) associated
E) circumstances
F) competitive
G) conceded
H) consciousness
I) desires
J) excluded
K) feature
L) lonely
M) separate
N) spectacularly
O) warrant
答案：
26.B 27.L 28.K 29.A 30.O 31.C 32.E 33.G 34.D 35.H
26、E circumstances
解析：certain之后加名词，之前没有冠词a，之后加名词的复数，under certain circumstances 为固定搭配。
27、L lonely
解析：和后文中认为自己的感觉是孤立的…之中的isolated相对，选孤单、孤立的含义，故选lonely。
28、H consciousness
解析：attribute之后为名词，和前文中认为自己的感觉是孤立的…之中的feeling相对，选感觉、意识的含义，故选consciousness。
29、A alleviate
解析：感觉亲近可以缓解孤单，根据语义，前后文的逻辑，故为alleviate。
30、J excluded
解析：现在完成时的被动语态，选ved，考虑G和J，G含义为退让，和原文不符，故选J。
31、B apparently
解析：这里需要使用副词对于动词substituted 进行修饰，选项中只有一个adv，故选apparently。
32、I desires
解析：这里的词应该和and 之前的beliefs进行含义和词性上的并列，故填n复数，选择含义相近的desires。
33、D associated
解析：be动词之后的选项都比较难，这里的提示为be…with, be associated with 为固定搭配，故选associated。
34、F competitive
解析：这里in…situations，应当填到的词汇为adj修饰n，其他的选项和situations不搭配，故选competitive
35、K feature
解析：this之后加名词单数，剩余选项为warrant，含义为许可证，和原文毫无关系，后文中a car’s friendliness 为特征，故选feature

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 for each item on Answer Sheet 2.
[A] Though he didn’t come from a farming family, from a young age Tim Joseph was fascinated by the idea of living off the land. Reading magazines like the Stockman Grass Farmer and Graze, he got hooked on the idea of grass-fed agriculture. The idea that all energy and wealth comes from the sun really intrigued him. He thought the shorter the distance between the sun and the end product, the higher the profit to the farmer.
[B] Joseph wanted to put this theory to the test. In 2009, he and his wife Laura launched Maple Hill Creamery, an organic, all grass-fed yogurt company in northern New York. He quickly learned what the market has demonstrated: Demand for grass-fed products currently exceeds supply. Grass-fed beef is enjoying a 25-30% annual growth rate. Sales of grass-fed yogurt and kefir(发酵乳饮品), on the other hand, have in the last year increased by over 38%. This is comparison with a drop of just under 1% in the total yogurt and kefir market, according to natural and organic market research company SPINS. Joseph’s top priority became getting his hands on enough grass-fed milk to keep customers satisfied，since his own 64-cow herd wasn’t going to suffice.
[C] His first partnership was with Paul and Phyllis Amburgh, owners of the Dharma Lea farm in New York. The Amburghs, too, were true believers in grass-fed. In addition to supplying milk from their own 85-head herd, they began to help other farmers in the area convert from conventional to certified organic and grass-fed in order to enter the Maple Hill supply chain. Since 2010, the couple has helped 125 small dairy farms convert to grass-fed, with more than 80% of those farms coming on board during the last two years.
[D] All this conversion has helped Maple Hill grow 40-50% every year since it began, with no end in sight, Jospeh has learned that a farmer has to have a certain mindset to successfully convert. But convincing open-minded dairy people is actually not that hard, when you look at the economics. Grass-fed milk can fetch up to 2.5 times the price of conventional milk. Another factor is the squeeze that conventional dairy farmers have felt as the price of grain they feed their cows has gone up, tightening their profit margins. By replacing expensive grain feed with regenerative management practices, grass-fed farmers are insulated from jumps in the price of feed. These practices include grazing animals on grasses grown from the pastureland’s natural seed bank, and fertilized by the cows’ own fertilizer.
[E] Champions of this type of regenerative grazing also point to its animal welfare, climate and health benefits: Grass-fed animals live longer out of confinement, Grazing herds stimulate microbial(微生物的)activity in the soil, helping to capture water and separate carbon. And grass-fed dairy and meat have been shown to be higher in certain nutrients and healthy fats.
[F] In the grass-fed system, farmers are also not subject to the wildly fluctuating milk prices of the international commodity market. The unpredictability of global demand and the lag-time it takes to add more cows to a herd to meet demand can result in events like the recent cheese surplus. Going grass-fed is a safe refuge, a way for family-scale farms to stay viable. Usually a farmer will get to the point where financially, what they’re doing is not working. That’s when they call Maple Hill. If the farm is well managed and has enough land, and the desire to convert is sincere, a relationship can begin. Through regular regional educational meetings, a large annual meeting, individual farm visits and thousands of phone calls, the Amburghs pass on the principles of pasture management. Maple Hill signs a contract pledging to buy the farmer’s milk at a guaranteed base price, plus quality premiums and incentives for higher protein, butter-fat and other solids.
[G] While Maple Hill’s conversion program is unusually hands-on and comprehensive, it’s just one of a growing number of businesses committed to slowly changing the way America farms. Joseph calls sharing his knowledge network through peer-to-peer learning a core piece of the company’s culture. Last summer, Massachusetts grass-fed beef advocate John Smith launched Big Picture Beef, a network of small grass-fed beef farms in New England and New York that is projected to bring to market 2,500 head of cattle from 125 producers this year. Early indications are that Smith will have no shortage of farm members. Since he began to informally announce the network at farming conferences and on social media, he’s received a steady stream of inquiries from interested farmers.
[H] Smith says he’ll provide services ranging from formal seminars to on-farm workshops on holistic(整体的) management, to one-on-one hand-holding and an almost 24/7 phone hotline for farmers who are converting. In exchange, he guarantees an above-market price for each animal and a calf-to-customer electronic ear tag ID system like that used in the European Union.
[I] Though advocates portray grass-fed products as a win-win situation for all, they do have downsides. Price, for one, is an issue. Joseph says his products are priced 10-20% above organic versions, but depending on the product chosen, compared to non-organic conventional yogurt, consumers could pay a premium of 30-50% or more for grass-fed. As for the meat, Smith says his grass-fed hamburger will be priced 20-25% over the conventional alternative. But a look at the prices on online grocer Fresh Direct suggests a grass-fed premium of anywhere from 35-60%.
[J] And not every farmer has the option of going grass-fed. For both beef and dairy production, it requires, at least in the beginning, more pastureland. Grass-fed beef production tends to be more labor-intensive as well. But Smith counters that if you factor in the hidden cost of government corn subsidies, environment degradation, and decreased human health and animal welfare, grass-fed is the more cost-effective model. "The sun provides the lowest cost of production and the cheapest meat," he says.
[K] Another grass-fed booster spurring farmers to convert is EPIC, which makes meat-based protein bars. Founders Taylor Collins and his wife, Katie Forrest, used to be endurance athletes; now they’re advocates of grass-fed meat. Soon after launching EPIC’s most successful product-the Bison Bacon Cranberry Bar-Collins and Forrest found they’d exhausted their sources for bison(北美野牛) raised exclusively on pasture. When they started researching the supply chain, they learned that only 2-3% of all bison is actually grass-fed. The rest is feed-lot confined and fed grain and corn.
[L] But after General Mills bought EPIC in 2016, Collins and Forrest suddenly had the resources they needed to expand their supply chain. So the company teamed up with Wisconsin-based rancher Northstar Bison. EPIC fronted the money for the purchase of $2.5 million worth of young bison that will be raised according to its grass-fed protocols, with a guaranteed purchase price. The message to young people who might not otherwise be able to afford to break into the business is, “You can purchase this $3 million piece of land here, because I’m guaranteeing you today you’ll have 1,000 bison on it.’ We’re bringing new blood into the old, conventional farming ecosystem, which is really cool to see," Collins explains.
36. Farmers going grass-fed are not affected by the ever-changing milk prices of the global market.
37. Over the years, Tim Joseph’s partners have helped many dairy farmers to switch to grass-fed.
38. One advocate believes that many other benefits should be taken into consideration when we assess the cost-effectiveness of grass-fed farming.
39. Many dairy farmers were persuaded to switch to grass-fed when they saw its advantage in terms of profits.
40. Tim Joseph’s grass-fed program is only one example of how American farming practice is changing.
41. Tim Joseph was fascinated by the notion that sunlight brings energy and wealth to mankind.
42. One problem with grass-fed products is that they are usually more expensive than conventional ones.
43. Grass-fed products have proved to be healthier and more nutritious.
44. When Tim Joseph started his business, he found grass-fed products fell short of demand.
45. A snack bar producer discovered that the supply of purely grass-fed bison meat was scarce.

题目以考察主旨题和细节题为主，并且是支撑主旨的主要细节。考生可根据题干关键词，迅速定位题干在原文中的位置，找到对应的描述及理解句子意思即可。答案句通常为原文句子的同义替换。需要格外注意的是，有一些选项很具有迷惑性，也存在一定程度的同义替换表达或原文原词重现，但实则是将一些信息杂糅的选项。对此，考生在做题时需要注意题目、选项和原文的对应，仔细辨别，避免错选。
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 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.
Schools are not just a microcosm(缩影) of society; they mediate it too. The best seek to alleviate the external pressures on their pupils while equipping them better to understand and handle the world outside-at once sheltering them and broadening their horizons. This is ambitious in any circumstances, and in a divided and unequal society the two ideals can clash outright(直接地).
Trips that many adults would consider the adventure of a lifetime-treks in Borneo, a sports tour to Barbados-appear to have become almost routine at some state schools. Parents are being asked for thousands of pounds. Though schools cannot profit from these trips, the companies that arrange them do. Meanwhile, pupils arrive at school hungry because their families can't afford breakfast. The Child Poverty Action Group says nine out of 30 in every classroom fall below the poverty line. The discrepancy is startlingly apparent. Introducing a fundraising requirement for students does not help, as better-off children can tap up richer aunts and neighbours.
Probing the rock pools of a local beach or practising French on a language exchange can fire children's passions. boost their skills and open their eyes to life's possibilities. Educational outings help bright but disadvantaged students to get better scores in A-level tests. In this globalised age, there is a good case for international travel, and some parents say they can manage the cost of a school trip abroad more easily than a family holiday. Even in the face of immense and mounting financial pressures, some schools have shown remarkable determination and ingenuity in ensuring that all their pupils are able to take up opportunities that may be truly life-changing. They should be applauded. Methods such as whole-school fundraising, with the proceeds(收益) pooled, can help to extend opportunities and fuel community spirit.
But £3,000 trips cannot be justified when the average income for families with children is just over £30,000. Such initiatives close doors for many pupils. Some parents pull their children out of school because of expensive field trips. Even parents who can see that a trip is little more than a party or celebration may well feel guilt that their child is left behind.
The Department for Education's guidance says schools can charge only for board and lodging if the trip is part of the syllabus, and that students receiving government aid are exempt from these costs. However, many schools seem to ignore the advice; and it does not cover the kind of glamorous, exotic trips, which are becoming increasingly common. Schools cannot be expected to bring together communities single-handed. But the least we should expect is that they do not foster divisions and exclude those who are already disadvantaged.
46. What does the author say best schools should do?
A) Prepare students to both challenge and change the divided unequal society.
B) Protect students from social pressures and enable them to face the world.
C) Motivate students to develop their physical as well as intellectual abilities.
D) Encourage students to be ambitious and help them to achieve their goals.
47. What does the author think about school field trips?
A) They enable students from different backgrounds to mix with each other.
B) They widen the gap between privileged and disadvantaged students.
C) They give the disadvantaged students a chance to see the world.
D) They only benefit students with rich relatives and neighbours.
48. What does the author suggest can help build community spirit?
A) Events aiming to improve community services.
B) Activities that help to fuel students' ingenuity.
C) Events that require mutual understanding.
D) Activities involving all students on campus.
49. What do we learn about low-income parents regarding school field trips?
A) They want their children to participate even though they don't see much benefit.
B) They don't want their kids to participate but find it hard to keep them from going.
C) They don't want their kids to miss any chance to broaden their horizons despite the cost.
D) They want their children to experience adventures but they don't want them to run risks.
50. What is the author's expectation of schools?
A) Bringing a community together with ingenuity.
B) Resolving the existing discrepancies in society.
C) Avoiding creating new gaps among students.
D) Giving poor students preferential treatment.
46、B) Protect students from social pressures and enable them to face the world.

Passage Two
Questions 51 to 55 arebased on the following passage.
Rising temperatures and overfishing in the pristine(未受污染的)waters around the Antarctic could see King penguin populations pushed to the brink of extinction by the end of the century, according to a new study. The study's report states that as global warming transforms the environment in the world's last great wilderness, 70 percent of king penguinscould either disappear or beforced to find new breeding grounds.
Co-author Céline Le Bohec, from the University of Strasbourg in France, warned: "If there’re no actions aimed at halting or controlling global warming, and the pace of the currenthuman-induced changes such as climate change and overfishing stays the same, the speciesmay soon disappear.” The findings come amid growing concern over the future of the Antarctic. Earlier this month a separate study found that a combination of climate change and industrial fishing is threatening the krill(磷虾)population in Antarctic waters,with a potentially disastrous impact on whales, seals and penguins. But today's report is the starkest warning yetof the potentially devastating impact of climate change and human exploitation on theAntarctic's delicate ecosystems.
Le Bohec said: “Unless current greenhouse gas emissions drop, 70 percent of king penguins- 1.1 million breeding pairs-will be forced to relocate their breeding grounds, orface extinction by 2100.”King penguins are the second-largest type of penguin and only breedon specific isolated islands in the Southern Ocean where there is no ice cover and easy accessto the sea. As the ocean warms, a body of water called the Antarctic Polar Front-an upwardmovement of nutrient-rich sea that supports a huge abundance of marine life-is being pushedfurther south. This means that king penguins, which feed on fish and krill in this body of water,have to travel further to their feeding grounds, leaving their hungry chicks for longer. And as this distance between their breeding grounds and their food grows, entire colonies could bewiped out.
Le Bohec said: "The plight of the king penguin should serve as a warning about the future of entire marine environment in the Antarctic. Penguins, like other seabirds and marinemammals, occupy higher levels in the food chain and they are what we call bio-indicators oftheir ecosystems." Penguins are sensitive indicators of changes in marine ecosystems. As such,they are key species for understanding and predicting impacts of global change on Antarcticand sub-Antarctic marine ecosystems. The report found that although some king penguins maybe able to relocate to new breeding grounds closer to their retreating food source, suitable new habitats would be scarce. Only a handful of islands in the Southern Ocean are suitable forsustaining large breeding colonies.
51. What will happen by 2100, according to a new study?
A) King penguins in the Antarctic will be on the verge of dying out.
B) Sea water will rise to a much higher level around the Antarctic.
C) The melting ice cover will destroy the great Antarctic wilderness.
D) The pristine waters around the Antarctic will disappear forever.
52. What do we learn from the findings of a separate study?
A) Shrinking krill population and rising temperatures could force Antarctic whales to migrate.
B) Human activities have accelerated climate change in the Antarctic region in recent years.
C) Industrial fishing and climate change could be fatal to certain Antarctic species.
D) Krill fishing in the Antarctic has worsened the pollution of the pristine waters.
53. What does the passage say about king penguins?
A) They will turn out to be the second-largest species of birds to become extinct.
B) Many of them will have to migrate to isolated islands in the Southern Ocean.
C) They feed primarily on only a few kinds of krill in the Antarctic Polar Front.
D) The majority of them may have to find new breeding grounds in the future.
54. What happens when sea levels rise in the Antarctic?
A) Many baby king penguins can't have food in time.
B) Many king penguins could no longer live on krill.
C) Whales will invade king penguins' breeding grounds.
D) Whales will have to travel long distances to find food.
55. What do we learn about the Southern Ocean?
A) The king penguins there are reluctant to leave for new breeding grounds.
B) Its conservation is key to the sustainable propagation of Antarctic species.
C) It is most likely to become the ultimate retreat for species like the king penguin.
D) Only a few of its islands can serve as huge breeding grounds for king penguins.
51、A) King penguins in the Antarctic will be on the verge of dying out.
解析：定位首段首句“Rising temperatures and overfishing in the pristine(未受污染的) waters around the Antarctic could see King penguin populations pushed to the brink of extinction by the end of the century, according to a new study.”本句大意：上升的气温和在未受污染水域的过度捕捞使得帝企鹅在本世纪末处于灭绝的边缘，故选A
干扰项：不在定位处。
52、C) Industrial fishing and climate change could be fatal to certain Antarctic species.

解析：定位三段倒数二句“This means that king penguins, which feed on fish and krill in this body of water, have to travel further to their feeding grounds, leaving their hungry chicks for longer.”那意味着吃鱼和磷虾的帝企鹅要走更远才能到他们进食的地方，这使得他们的孩子饿得更久，故选A。

55、D) Only a few of its islands can serve as huge breeding grounds for king penguins.
解析：定位尾段后一句“Only a handful of islands in the Southern Ocean are suitable for sustaining large breeding colonies.”大意为：只有少量的岛屿是适合去维持大量的需要进食的移民者(语境内为帝企鹅)。故选D。
