18、nk about the rhythm of your typing. Not only can it be used to identify you, it can reveal if you are in a stressful environment. It has long been known that the rhythms of a person“s typing style are 1 over time, leading to suggestions they could be used to 2 identity or even spot early signs of Al

19、zheimer“s disease. But little was known about the effect of stress on typing 3 , so psychologist Mike Dowman and colleagues at the University of Abertay investigated. They asked 35 people to log into a computer 36 times over three 4 sessions up to a month apart, using the same username and password.

20、 People were put into 5 and relaxed states alternately (交替地) by listening to a range of sounds known to 6 particular emotions. The length of time each key was held down and the 7 between one being released and another pressed was recorded to generate a typing “fingerprint“ for each person. The team

21、used the data to develop and test software that identifies a person from their typing style 8 . The data also showed that stress can be 9 in a person“s typing because it changes the pattern of timings. “There“s no question: people do type 10 under stress,“ says Dowman. He suggests that security syst

22、ems could be designed to raise the alarm if it seems that a person might be being forced to log into a system. More research will be needed, however, before a system could tell if a person is, say, just having a bad day or being held at gunpoint. A. stressed E. interval I. differently M. normally B.

It“s everyone else“s fault. Even i

24、f I turn off my air conditioner, it will make no difference.“ The list of reasons for not acting to combat global warming goes on and on. This month, American Psychological Association (APA) released a report highlighting these and other psychological barriers standing in the way of action. But don“

25、t despair. The report also points to strategies that could be used to convince us to play our part. Sourced from psychological experiments, we review tricks that could be used by companies or organisations to encourage climate-friendly behaviour. In addition, psychologist Mark van Vugt of the Free U

26、niversity of Amsterdam describes the elements of human nature that push us to act unselfishly. B. As advertisers of consumer products well know, different groups of people may have quite distinct interests and motivations, and messages that seek to change behaviour need to be tailored to take these

27、into account. “You have to target the marketing to a particular sector of the population,“ says Robert Gifford of the University of Victoria, another of the report“s authors. The wealthy young, for instance, tend to be diet conscious, and this could be used to steer them away from foods like cheeseb

28、urgersone of the most climate-unfriendly meals around because of the energy it takes to raise cattle. So when trying to convince them to give up that carbon-intensive beef pie, better to stress health benefits than the global climate. C. Though conservative authorities have been known to attack such

29、 efforts, characterising them as mind control, experiments indicate that people are willing to be persuaded. “From participants in our experiments, we“ve never heard a negative feedback,“ says Wesley Schultz of California State University. In fact, according to John Petersen of Oberlin College, we a

30、re used to far worse. “Compared to the overwhelming number of advertising, it seems milder than anything I experience in my daily life,“ he says. D. Deep down, most of us want to fit in with the crowd, and psychologists are exploiting this urge to encourage environmentally friendly behaviour. Resear

31、chers led by Wesley Schultz at California State University and Jessica Nolan, now at the University of Scranton, have found that people will cut their electricity usage if told that their neighbours use less than they do. In one experiment, the researchers left information with households in San Mar

32、cos asking them to use fans rather than air conditioners at night, turn off lights and take shorter showers. Some messages simply stressed energy conservation, some talked about future generations, while others emphasised the financial savings. But it was the flyers (传单) that asked residents to join

33、 with their neighbours in saving energy that were most effective in cutting electricity consumption. E. In another study, the researchers told households what others in their neighbourhood used on average. High users cut their consumption in response, but low users increased theirs. The problem disa

34、ppeared if the messages were reinforced with sad or smiling faces. The smiles received by the residents who were already saving energy provided sufficient encouragement for them to keep doing so. F. Most people seem to conserve energy if provided with real-time feedback on how much they are using. B

35、ut feedback can be too immediate. For instance, Janet Swim has a General Motors car that shows her mileage (里程) per gallon each time she accelerates. It“s just not very useful, she argues, because it“s hard to place that momentary piece of feedback in the context of her overall driving behaviour and

36、 fuel efficiency. In contrast, the Toyota Prius display shows mileage per gallon over 5-minute intervals for the previous half-hour. With that contextual information, people can experiment with different driving styles to see how they affect mileage, and even compete with themselves to improve over

37、time. The 2010 Honda Insight goes one better, flashing up an image of a prize to reward economical driving. The benefits of feedback are not restricted to car gadgets (小装置). Studies show that devices that display domestic energy usage produce savings of between 5 and 12 per cent. G. People have to b

38、e persuaded to act on climate change even though the benefit won“t be felt for decades. Research by David Hardisty and Elke Weber of Columbia University suggests ways to achieve this. Hardisty and Weber have found that people respond in exactly the same way to decisions involing future environmental

39、 gains and losses as they do when making financial decisions. This allows psychologists“ knowledge of how to control financial decision-making to be brought into play. For instance, schemes that give people a cash payment in advance for insulating (使隔热) their home will work better than those promisi

40、ng long-term savings, even if the people receiving cash end up paying a little more in the long run. H. And because we are generally more worried about future losses than we are impressed by future gains, messages are more effective if framed to warn people that they will lose $500 over 10 years if

41、they don“t follow a particular course of action to limit climate change than if they are told they“ll be $500 better off if they do take action. I. As social animals, we like to interact with others and take inspiration from their actions. Psychologists are working out how to exploit this to spread

42、behaviours that will help limit climate change. “My sense is that social networks are going to be important,“ says Swim. Allowing people to document successes in saving energy on their Facebook pages could drive change among their friends, and the Oberlin team is considering integrating this into it

43、s urban residence experiment. Tawanna Dillahunt and colleagues at Carnegie Mellon University, think such opportunities presented by Facebook can be combined with our liking for animals. Inspired by the attachment that people can develop towards Tamagotchi virtual pets, the team is testing the compel

44、ling power of a “virtual polar bear“ standing on a sheet of floating ice that grows bigger as people adopt environmentally friendly behaviours such as taking shorter showers. Initial results suggest the polar bear has pull.（分数：70.00）(1).Flyers related with neighbours“ behaviour are a very effective

45、way to convince residents to cut electricity consumption.（分数：7.00）(2).According to Swim, social network will be important to spread behaviours that will help limit climate change.（分数：7.00）(3).The research by Hardisty and Weber aims at seeking ways to convince people to limit climate change.（分数：7.00）

46、(4).It“s better to persuade the wealthy young out of carbon-intensive food by emphasizing health benefits.（分数：7.00）(5).In the experiment by Wesley Schultz, no participant lodged a complaint.（分数：7.00）(6).When talking people into taking action, it“s more effective to tell them future losses than futur

48、ng to Tawanna Dillahunt and colleagues, successes in saving energy by Facebook and our liking for animals can be combined.（分数：7.00）(10).The 2010 Honda Insight has a device that encourages drivers to drive economically.（分数：7.00）十四、Section C(总题数：0，分数：0.00)十五、Passage One(总题数：1，分数：71.50)It“s hot now in

49、Afghanistan, where 35% of the population is under-fed. But soon it will be cold, and many“ of the country“s roads will become inaccessible because of snow and landslides, making it difficult to get food to market. Knowing these things gets Stacy McCoy out of bed every morning and out into the countryside, visiting Afghani women and farmers to offer new agricultural techniques and hardier seeds. She also works to improve their marketing skills so that they can be exposed to new ways to sell goods
