23、.Questions 26 to 35 are based on the following passage.The number of devices you can talk to is multiplyingfirst it was your phone, then your car, and now you can tell your kitchen appliances what to do. But even without gadgets that understand our spoken commands, research suggests that, as bizarre
24、 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
25、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 friendsunless they were first given tasks that caused them to interact with their phone as if it had human qualities. According to the researchers,
26、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
27、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 themespecially i
28、n 34 situations. An analysis of car sales in Germany found that cars with gills (护栅) that were upturned like smiles sold best. The purchasers saw this 35 as increasing a cars friendliness.A) alleviate I) desiresB) apparently J) excludedC) arrogant K) featureD) associated L) lonelyE) circumstances M)
29、 separateF) competitive N) spectacularlyG) conceded O) warrantH) consciousnessSection BDirections: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
30、 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 onAnswer Sheet 2.A Though he didnt come from a farming family, from a young age Tim Joseph was fascinated by the idea of living off the land. Readi
31、ng 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
32、 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
33、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 in comparison with a drop of just under 1% in the total yogurt and kefir market according to natural and organic market research company SPINS. Josephs top
34、 priority became getting his hands on enough grass-fed milk to keep customers satisfied, since his own 64-cow herd wasnt going to sufficeC 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 addit
35、ion to supplying milk from their own 85-head herd, they began to help other farmers in the area convent 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%
36、 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. Joseph has learned that a farmer has to have a certain mindset to successfully convert. But convincing open-minded dairy people is actuall
37、y 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 expe
38、nsive 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 pasturelands natural seed bunk, and fertilized by the cows own fertilizerE Champions of this type of regenerativ
39、e 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
40、 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 rec
41、ent 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 theyre doing is not working. Thats when they call Maple Hill. If the farm is well managed and has enough land, and the desire to convert i
42、s 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 farmers milk at a guaranteed bas
43、e price, plus quality premiums and incentives for higher protein, butter fat and other solids.G While Maple Hills conversion program is unusually hands on and comprehensive, its just one of a growing number of businesses committed to slowly changing the way America farms. Joseph calls sharing his kn
44、owledge network through peer-to-peer learning a core piece of the companys 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 f
45、rom 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, hes received a steady stream of inquiries from interested farmers.H Smith says hell provide services rang
46、ing 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
47、in the European Union.1 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
48、, 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 t
