Answer the questions by marking the corresponding letteron Answer Sheet 2.Peer Pressure Has a Positive SideA Parents of teenagers often view their childrens friends with some
11、thing likesuspicion. They worry that the adolescent peer group has the power to push itsmembers into behavior that is foolish and even dangerous. Such wariness is wellfounded: statistics show, for example, that a teenage driver with a same-age passengerin the car is at higher risk of a fatal crash t
12、han an adolescent driving alone or with anadult.B In a 2005 study, psychologist Laurence Steinberg of Temple University andhis co-author, psychologist Margo Gardner, then at Temple, divided 306 people intothree age groups: young adolescents, with a mean age of 14; older adolescents, with amean age o
13、f 19; and adults, aged 24 and older. Subjects played a computerizeddriving game in which the player must avoid crashing into a wall that materializes,without warning, on the roadway. Steinberg and Gardner randomly assigned someparticipants to play alone or with two same-age peers looking on.C Older
14、adolescents scored about 50 percent higher on an index of riskydriving when their peers were in the roomand the driving of early adolescents wasfully twice as reckless when other young teens were around. In contrast, adultsbehaved in similar ways regardless of whether they were on their own or obser
15、ved byothers. The presence of peers makes adolescents and youth, but not adults, morelikely to take risks， Steinberg and Gardner concluded.D Yet in the years following the publication of this study, Steinberg began tobelieve that this interpretation did not capture the whole picture. As he and other
16、researchers examined the question of why teens were more apt to take risks in thecompany of other teenagers, they came to suspect that a crowd s influence need notalways be negative. Now some experts are proposing that we should take advantageof the teen brains keen sensitivity to the presence of fr
17、iends and leverage it toimprove education.E In a 2011 study, Steinberg and his colleagues turned to functional MRI (磁共振） to investigate how the presence of peers affects the activity in the adolescent brain.They scanned the brains of 40 teens and adults who were playing a virtual drivinggame designe
18、d to test whether players would brake at a yellow light or speed onthrough the crossroad.F The brains of teenagers, but not adults, showed greater activity in two regionsassociated with rewards when they were being observed by same-age peers than whenalone. In other words,rewards are more intense fo
19、r teens when they are with peers,which motivates them to pursue higher-risk experiences that might bring a big payoff(such as the thrill of just making the light before it turns red). But Steinberg suspectedthis tendency could also have its advantages. In his latest experiment, publishedonline in Au
20、gust, Steinberg and his colleagues used a computerized version of a cardgame called the Iowa Gambling Task to investigate how the presence of peers affectsthe way young people gather and apply information.G The results: Teens who played the Iowa Gambling Task under the eyes offellow adolescents enga
21、ged in more exploratory behavior，learned faster from bothpositive and negative outcomes，and achieved better performance on the task thanthose who played in solitude. What our study suggests is that teenagers learn morequickly and more effectively when their peers are present than when they re on the
22、irown， Steinberg says.And this finding could have important implications for how wethink about educating adolescents.H Matthew D. Lieberman, a social cognitive neuroscientist at the University ofCalifornia, Los Angeles, and author of the 2013 book Social: Why Our Brains AreWired to Connect，suspects
23、that the human brain is especially skillful at learningsocially significant information. He points to a classic 2004 study in whichpsychologists at Dartmouth College and Harvard University used functional MRI totrack brain activity in 17 young men as they listened to descriptions of people whileconc
24、entrating on either socially relevant cues ( for example ， trying to form animpression of a person based on the description) or more socially neutral information(such as noting the order of details in the description). The descriptions were the samein each condition, but people could better remember
25、 these statements when given asocial motivation.I The study also found that when subjects thought about and later recalleddescriptions in terms of their informational content, regions associated with factualmemory, such as the medial temporal lobe, became active. But thinking about orremembering des
26、criptions in terms of their social meaning activated the dorsomedialprefrontal cortexpart of the brains social networkeven as traditional memoryregions registered low levels of activity. More recently, as he reported in a 2012review, Lieberman has discovered that this region may be part of a distinc
27、t networkinvolved in socially motivated learning and memory. Such findings, he says, suggestthat this network can be called on to process and store the kind of information taughtin schoolpotentially giving students access to a range of untapped mental powers.J If humans are generally geared to recal
28、l details about one another, this patternis probably even more powerful among teenagers who are very attentive to socialdetails: who is in, who is out, who likes whom, who is mad at whom. Their desire forsocial drama is notor not onlya way of distracting themselves from theirschoolwork or of driving
29、 adults crazy. It is actually a neurological (神经的) sensitivity,initiated by hormonal changes. Evolutionarily speaking, people in this age group areat a stage in which they can prepare to find a mate and start their own family whileseparating from parents and striking out on their own. To do this suc
30、cessfully, theirbrain prompts them to think and even obsess about others.K Yet our schools focus primarily on students as individual entities. Whatwould happen if educators instead took advantage of the fact that teens are powerfullycompelled to think in social terms? In Social， Lieberman lays out a
31、 number of ways todo so. History and English could be presented through the lens of the psychologicaldrives of the people involved. One could therefore present Napoleon in terms of hisdesire to impress or Churchill in terms of his lonely gloom. Less inherentlyinterpersonal subjects, such as math, co
32、uld acquire a social aspect through teamproblem solving and peer tutoring. Research shows that when we absorb informationin order to teach it to someone else, we learn it more accurately and deeply, perhaps inpart because we are engaging our social cognition.L And although anxious parents may not we
33、lcome the notion, educators couldturn adolescent recklessness to academic ends. Risk taking in an educational contextis a vital skill that-enables progress and creativity, wrote Sarah-Jayne Blakemore, acognitive neuroscientist at University College London, in a review published last year.Yet, she no
34、ted, many young people are especially unwilling to take risks atschoolafraid that one low test score or poor grade could cost them a spot at aselective university. We should assure such students that risk, and even peer pressure,can be a good thingas long as it happens in the classroom and not in th
35、e car.36. It is thought probable that the human brain is particularly good at picking upsocially important information.37. It can be concluded from experiments that the presence of peers increasesrisk-taking by adolescents and youth.38. Students should be told that risk-taking in the classroom can b

According to Steinberg, the presence of peers increases the speed andeffectiveness of teenagerslearning.41. Teenagers parents are often concerned about negative
37、 peer influence.42. Activating the brains social network involved in socially motivated learningand memory may allow students to tap unused mental powers.43. The presence of peers intensifies the feeling of rewards in teens brains.44. When we absorb information for the purpose of imparting it to oth
38、ers, we doso with greater accuracy and depth.45. Some experts are suggesting that we turn peer influence to good use ineducation.Section CDirections: There are 2 passages in this section. Each passage is followed by somequestions or unfinished statements. For each of them there are fourchoices marke

You should decide on the best choiceand mark the corresponding letter on Answer Sheet 2with a single linethrough the centre.Passage OneQuestions 46 to 50 are based on the following passage.The Ebro Delta, in Spain, famous as a battleground during the Spanish Civil War,is now the
40、 setting for a different contest, one that is pitting rice farmers against twoenemies：the rice-eating giant apple snail, and rising sea levels. What happens herewill have a bearing on the future of European rice production and the overall health ofsouthern European wetlands.Located on the Mediterran
41、ean just two hours south of Barcelona, the Ebro Deltaproduces 120 million kilograms of rice a year, making it one of the continents mostimportant rice-growing areas. As sea creeps into these fresh-water marshes, however,rising salinity (盐分）is hampering rice production. At the same time, this sea-wat

The most promising strategy has become to harness one foe against the other.The battle is currently being waged on land, in greenhouses at the University ofBarcelona. Scientists working under the banner
43、 Project Neurice are seekingvarieties of rice that can withstand the increasing salinity without losing theabsorbency that makes European rice ideal for traditional Spanish and Italian dishes.The project has two sides，says Xavier Serrat，Neurice project manager andresearcher at the University of Barc
44、elona, the short-term fight against the snail, and amid-to long-term fight against climate change. But the snail has given the projectgreater urgency. Originally from South America, the snails were accidentally introduced into theEbro Delta by Global Aquatic Technologies, a company that raised the s
45、nails forfresh-water aquariums (水族馆） ， but failed to prevent their escape. For now, the giantapple snails presence in Europe is limited to the Ebro Delta. But the snail continuesits march to new territory, says Serrat. The question is not whether it will reach otherrice-growing areas of Europe, but
46、when.Over the next year and a half investigators will test the various strains ofsalt-tolerant rice theyve bred. In 2018, farmers will plant the varieties with the mostpromise in the Ebro Delta and Europes other two main rice-growing regionsalongthe Po in Italy, and Frances Rhone. A season in the fi
47、eld will help determine which, ifany, of the varieties are ready for commercialization.As an EU-funded effort, the search for salt-tolerant varieties of rice is takingplace in all three countries. Each team is crossbreeding a local European short-grainrice with a long-grain Asian variety that carrie
