Each choice in the bank isidentified by a letter.Please mark the corresponding letter for each item on AnswerSheet 2 with a single line through the centre.You may not use any of the words in thebank more than once.Questions 36 to 45 are based on the following passage.As it is, sleep is so undervalued that getting by on fewer hours has become a badge of honor.Plus, we live in a culture that 36 to the late-nighter, from 24-hour grocery stores to onlineshopping sites that never close.Its no surprise, then, that more than half of American adults dont getthe 7 to 9 hours of shut-eye every night as 37 by sleep experts.Whether or not we can catch up on sleep-on the weekend, say-is a hotly 38 topic amongsleep researchers.The latest evidence suggests that while it isnt 39 , it might help.When Liu, theUCLA sleep researcher and professor of medicine, brought 40 sleep-restricted people into the labfor a weekend of sleep during which they logged about 10 hours per night, they showed 41 in theability of insulin (胰岛素) to process blood sugar.That suggests that catch-up sleep may undo somebut not all of the damage that sleep 42 causes, which is encouraging, given how many adults dontget the hours they need each night.Still, Liu isnt 43 to endorse the habit of sleeping less andmaking up for it later.Sleeping pills, while helpful for some, are not 44 an effective remedy either.A sleeping pillwill 45 one area of the brain, but theres never going to be a perfect sleeping pill, because youcouldnt really replicate (复制 ) the different chemicals moving in and out of different parts of the brainto go through the different stages of sleep, says Dr.Nancy Collop, director of the Emory UniversitySleep Center.A.alternativelyB.catersC.chronicallyD.debatedE.deprivationF.idealG.improvementsH.necessarilyI.negotiatedJ.pierceK.presumptionL.readyM.recommendedN.surpassesO.targetSection BDirections: In this section, you are going to read a passage with ten statements attached to it.Eachstatement contains information given in one of the paragraphs.Identify the paragraphfrom 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 thecorresponding letter on Answer Sheet 2.Climate change may be real, but its still not easy being greenHow do we convince our inner caveman to be greener? We ask some outstanding social scientists.A The road to climate hell is paved with our good intentions.Politicians may tackle polluters whilescientists do battle with carbon emissions.But the most pervasive problem is less obvious: ourown behaviour.We get distracted before we can turn down the heating.We break our promise notto fly after hearing about a neighbours trip to India.Ultimately, we cant be bothered to changeour attitude.Fortunately for the planet, social science and behavioural economics may be able todo that for us.B Despite mournful polar beats and charts showing carbon emissions soaring, most people find ithard to believe that global warming will affect them personally.Recent polls by the Pew ResearchCentre in Washington, DC, found that 75-80 per cent of participants regarded climate change as animportant issue.But respondents ranked it last on a list of priorities.C This inconsistency largely stems from a feeling of powerlessness.When we cant actually removethe source of our fear, we tend to adapt psychologically by adopting a range of defencemechanisms, says Tom Crompton, change strategist for the environmental organisation WorldWide Fund for Nature. D Part of the fault lies with our inner caveman.Evolution has programmed humans to pay mostattention to issues that will have an immediate impact.We worry most about now because if wedont survive for the next minute, were not going to be around in ten years time, says ProfessorElke Weber of the Centre for Research on Environmental Decisions at Columbia University in NewYork.If the Thames were lapping around Big Ben, Londoners would face up to the problem ofemissions pretty quickly.But in practice, our brain discounts the risks-and benefits-associatedwith issues that lie some way ahead.E Matthew Rushworth, of the Department of Experimental Psychology at the University of Oxford,sees this in his lab every day.One of the ways in which all agents seem to make decisions is thatthey assign a lower weighting to outcomes that are going to be further away in the future, hesays.This is a very sensible way for an animal to make decisions in the wild and would havebeen very helpful for humans for thousands of years.F Not any longer.By the time we wake up to the threat posed by climate change, it could well betoo late.And ff were not going to make rational decisions about the future, others may have tohelp us to do so.G Few political libraries are without a copy of Nudge: Improving Decisions About Health, Wealthand Happiness, by Richard Thaler and Cass Sunstein.They argue that governments shouldpersuade us into making better decisions-such as saving more in our pension plans-by changingthe default options.Professor Weber believes that environmental policy can make use of similartactics.If, for example, building codes included green construction guidelines, most developerswould be too lazy to challenge them.H Defaults are certainly part of the solution.But social scientists are most concerned about craftingmessages that exploit our group mentality (, ).We need to understand what motivatespeople, what it is that allows them to make change, says Professor Neil Adger, of the TyndallCentre for Climate Change Research in Norwich.It is actually about what their peers think ofthem, what their social norms are, what is seen as desirable in society. In other words, ourinner caveman is continually looking over his shoulder to see what the rest of the tribe are up to. I The passive attitude we have to climate change as individuals can be altered by counting us in-and measuring us against-our peer group.Social norms are primitive and elemental, says Dr.Robert Cialdini, author of Influence: The Psychology of Persuasion.Birds flock together, fishschool together, cattle herd together.just perceiving norms is enough to cause people to adjusttheir behaviour in the direction of the crowd.J These norms can take us beyond good intentions.Cialdini conducted a study in San Diego inwhich coat hangers bearing messages about saving energy were hung on peoples doors.Some ofthe messages mentioned the environment, some financial savings, others social responsibility.Butit was the ones that mentioned the actions of neighbours that drove down power use.K Other studies show that simply providing the facility for people to compare their energy use withthe local average is enough to cause them to modify their behaviour.The Conservatives plan toadopt this strategy by making utility companies print the average local electricity and gas us
