Without culture, animals cope with life by instinct. Thus memory is necessary for them. By saying this, I also mean that people develop memory according to the needs of their lives. Every one of us, is connected to this vast and complex world in every moment, but dont receive all into our senses, which means we choose. We do not see everything that our eyes touch. We see only what we notice, because there is a focus in our sight which moves on the basis of our attention. And the object of attention is chosen by us, according to the needs of our life.9. 单选题Once upon a time, people believed staying a healthy weight was easy. To lose weight you simply had to practice the reverse of home economicsspend more than you earned. Unfortunately for many, but perhaps not surprisingly, it turns out that people are rather more complicated than bank accounts.To stay a healthy weight, you need a hormone called lepton to work properly. It sends “Im full” messages from the fat cells up to the brain, where they go, among other places, to the same pleasure centers that respond to drugs like cocaine. Fat people produce plenty of lepton, but the brain doesnt seem to respond to it properly. Last year researchers at the Oregon Research Institute scanned the brains of overweight people and found their reward circuit（线路）were underactive. They were eating more to try to get the enjoyment they were missing.Theres a lot of evidence for the fact that most, if not all, of us have a set point around which our weight can vary by about seven to nine kilos, but anything beyond that is a real struggle. Making changes is hard, particularly if your body is working against you. So why not reject the traditional approaches and try some new method, based on the latest research, that work with your body rather than against it.Several years ago researchers at the National Institute on Aging in Baltimore reported that when they gave rats very little food one day and allowed them to eat plenty the next, they showed virtually all the benefits of a permanent calorie restriction diet. The same goes for humans, according to Dr. James Johnson.How does it work? Besides forcing the body to burn fat, it may also cause hormonal changes. Most people say that the diet takes a bit of getting used to, but is not as grinding as trying to cut back on an everyday basis.Older dieters may remember something called brown fat. Unlike the undesirable white stuff; this was a dieters dream. Instead of storing excess energy as fat, brown-fat tissue burned it off to keep you warmat least in mice. Brown fat fell out of favor because researchers couldnt find much in humans but now, thanks to the New England journal of Medicine, its back in fashion. The idea is to expose people to cold temperatures. They then make more brown fat and their weight drops.1.The last sentence in paragraph 1 indicates that peoples understanding of losing weight（ ）.2.According to the findings of the Oregon Research Institute,（ ）.3.The method used by the National Institute on Aging can be summarized as “（ ）”.4.The word “grinding” in the paragraph 5 is closest in meaning to（ ）.5.It can be learned that brown fat（ ）.问题1选项A.is unnecessarily complicatedB.seems rather unreasonableC.used to be limitedD.can be partly justified问题2选项A.Overweight people got less pleasure from eating the same amountB.Overweight people enjoyed eating more than the others doC.People will become overweight if they eat more than they needD.People are more likely to be overweight if they produce less lepton问题3选项A.No diet at allB.Diet on a daily basisC.Diet every other dayD.Diet permanently问题4选项A.EffectiveB.RealisticC.UnreliableD.Miserable问题5选项A.converts excess energy into fatB.accumulates easily in human bodiesC.works better in warm temperaturesD.burns extra energy to produce heat【答案】第1题:C第2题:A第3题:C第4题:D第5题:D【解析】1.推理判断题。第一段说到“Once upon a time, people believed staying a healthy weight was easy.（从前，人们认为保持健康的体重很容易。）”；“Unfortunately for many, but perhaps not surprisingly, it turns out that people are rather more complicated than bank accounts.（不幸的是，对许多人来说，事实证明人比银行账户复杂得多，但这也许并不令人意外。）”，由这两句可以看出以前人们对减肥的概念很片面、有限，殊不知人体机能是很复杂的，所以最后一句话表明了人们对减肥的理解是很有限的，A选项“复杂难懂的”；B选项“似乎是相当不合理的”；D选项“部分可以被证明的”都不符合段意，因此C选项“过去是有限的”正确。2.事实细节题。the Oregon Research Institute的研究出现在第二段，原文“Last year researchers at the Oregon Research Institute scanned the brains of overweight people and found their reward circuit（线路） were underactive. They were eating more to try to get the enjoyment they were missing.（去年俄勒冈州研究所研究人员扫描超重的人，发现他们的大脑奖赏回路（线路）是不够的。他们吃得更多，试图获得他们错过的乐趣。）”的意思是胖的人和其他人吃同等数量的食物时，他们获得的乐趣会比其他人少，因为他们大脑中的奖赏回路不如其他人，因此会吃更多来试图获得乐趣。B选项“超重的人比其他人吃得更多”；C选项“如果人们吃得比需要的多，他们就会超重”；D选项“如果产生的瘦素较少，人们更有可能超重”都不是该研究的内容，因此A选项“超重的人在吃同样数量的食物时得到的快乐较少”正确。3.推理判断题。the National Institute on Aging的研究出现在第四段，原文说到“when they gave rats very little food one day and allowed them to eat plenty the next, they showed virtually all the benefits of a permanent calorie restriction diet.（当他们一天给老鼠很少的食物，第二天让它们吃大量的食物时，它们几乎显示出了长期限制卡路里饮食的所有好处。）”。所以这个方法可以总结为隔天节食。A选项“不节食”不正确；B选项“日常节食” 也不正确；D选项“永久性节食”也不是该研究的内容，因此C选项“隔天节食”正确。4.词义猜测题。第五段“but is not as grinding as trying to cut back on an everyday basis.（但并不像每天尝试节食那么痛苦。）”。grinding的意思是“无休止的；（状态）难熬的”，A选项Effective“有效的，实际的”；B选项Realistic“现实的，逼真的”；C选项Unreliable“不可靠的，靠不住的”；D选项Miserable“痛苦的，悲惨的”。因此D选项正确。5.事实细节题。brown fat出现在文章第六段。“Instead of storing excess energy as fat, brown-fat tissue burned it off to keep you warmat least in mice.（棕色脂肪组织并没有以脂肪的形式储存多余的能量，而是通过燃烧来保持体温至少在老鼠身上是这样的。）”，该句说明棕色脂肪燃烧多余的能量来产生热量。A选项“把多余的能量转化成脂肪”；B选项“容易在人体内积聚”；C选项“在温暖的温度下工作效果更好”都与原文事实不符，因此D选项“燃烧额外的能量产生热量”正确。10. 单选题You can always use（ ）glass if you need to block a street view.问题1选项A.convertibleB.decorousC.opaqueD.salient【答案】C【解析】考查词义辨析。A选项convertible“可改变的；可转换的；可兑换的”；B选项decorous“礼貌得体的”；C选项opaque“（玻璃、液体等）不透明的，不透光的，浑浊的”；D选项salient“显著的；最重要的”。句意：如果你需要遮挡街景，可以使用（ ）玻璃。opaque“（玻璃）不透明的，不透光的”，glass（玻璃）可以遮挡光，符合语境。因此C选项正确。11. 单选题I was（ ）by their kindness and moved to tears.问题1选项A.preoccupiedB.embarrassedC.overwhelmedD.counseled【答案】C【解析】考查形容词辨析。A选项preoccupied“使全神贯注，抢先占有”；B选项embarrassed“使困窘”；C选项overwhelmed“（情感）难以承受”；D选项counseled“被劝告”。句意：我被他们的善良（ ），感动得流下眼泪。overwhelmed“（情感）难以承受”和带有情绪色彩的move to tear搭配使句子通顺。因此C选项正确。12. 单选题Some years ago, Houston airport faced a troubling issue. Passengers were（1）about the long waits at baggage claim (行李提取处).（2）, the executives increased the number of baggage handlers. The plan（3）: the average wait fell to eight minutes, well within industry standard.（4）the complaints persisted.（5）, the airport executives undertook a more careful analysis.

Passengers now had to walk six times longer. Complaints dropped to near（9）.This story shows that the experience of waiting is defined only partly by the objective（10）of the wait. Occupied time (walking to baggage claim) feels（11）than unoccupied time (（12）at baggage claim). Research on queuing has shown that, people on average,（13）how long theyve waited in a line.This is also（14）one finds mirrors next to elevators.

Or 50. No one was certain of the true figure, but it was a lot. Visitors flocked from all comers of Europe to test him and came away stunned. Two condemned prisoners were due to be executed, but no one knew their language to hear their confession. Mezzofanti learned it in a night, heard their sins the next morning and saved them from hell.Or so the legend goes. In “Babel No More”, Michael Erard has written the first serious book about the people who master vast numbers of languagesor claim to. A journalist with some linguistics training, Mr. Erard is not a hyperpolyglot himself (he speaks some Spanish and Chinese), but he approaches his topic with both wonder and a healthy dash of scepticism.To find out whether anyone could really learn so many languages, Mr. Erard set out to find Modern Mezzofantis. The people he meets are certainly interesting. One man with a mental age of nine has a vast memory for foreign words and the use of grammatical endings, but he cannot seem to break free of English word order. Ken Hals, who was a linguist at the Massachusetts Institute of Technology and died in 2001, was said to have learned 50 languages. Professional linguists sill swear by his talent. But he insisted he spoke only three (English, Spanish and Warlpirifrom Australias Northern Territory) and could merely “talk” in others. Mr. Erard says that true hyperpolyglottery begins at about 11 languages, and that while legends abound, tried and tested exemplars are few.At the end of his story, however, Erard finds a surprise in Mezzofantis archive: flashcards. Stacks of them, in Georgian, Hungarian, Arabic, Algonquin and nine other tongues. The worlds most celebrated hyperpolyglot relied on the same tools given to first-year language learners today. The conclusion? Hyperpolyglots may begin with talent but they arent geniuses. They simply enjoy tasks that are drudgery to normal people. The talent and enjoyment drive a virtuous cycle that pushes them to feats others simply shake their heads at.1.The word “hyperpolyglot” (para. 2) refers to the one who（ ）.2.By “a healthy dash of skepticism”, the author demonstrates Mr. Erards（ ）.3.Mr. Erards efforts to find the Modern Mezzofantis（ ）.4.What is the emphasis in the last paragraph?5.The passage is most likely a part of（ ）.问题1选项A.enjoys learning languagesB.receives strict language trainingC.speaks many languagesD.excels in language tests问题2选项A.biased opinionB.objective attitudeC.strong motivationD.extreme curiosity问题3选项A.are not very fruitfulB.will not end in vainC.seem to pay offD.are highly appreciated问题4选项A.There is no shortcut in language learning.B.We all have the potential to be a good language learner.C.Some people are more gifted to learn languages.D.Good language learners have special learning techniques.问题5选项A.a research paperB.a science fictionC.a news reportD.a book review【答案】第1题:C第2题:B第3题:C第4题:A第5题:A【解析】1.语义推测题。根据第二段第三句A journalist with some linguistics training, Mr. Erard is not a hyperpolyglot himself (he speaks some Spanish and Chinese)，（埃拉尔是一名记者，接受过一些语言学训练，但他自己并不是（ ），他会说一点西班牙语和汉语），会说一点西班牙语和汉语用来补充解释前面的 hyperpolyglot，和C选项“会说多种语言”对应，hyperpolyglot是“语言狂人”，故C选项正确。A选项“喜欢学语言”文章没有提到。B选项“接受严格的语言训练”：Erard学过一些，说不上严格。D选项“擅长语言测试”，文章没有讲语言测试。因此C选项正确。2.语义推测题。根据第三段最后一句Mr. Erard says that true hyperpolyglottery begins at about 11 languages, and that while legends abound, tried and tested exemplars are few.（埃拉尔说，真正的语言狂人大约从会11种语言开始，虽然传说比比皆是，但经过验证的例子却很少。），可知实际上语言狂人没有大家所知的那么多，所以Erard的怀疑是客观的，故B选项“客观的态度”正确，A选项“有偏见的观点”错误。C选项“强烈的动机”和D选项“极度的好奇心”和事例无关。因此B选项正确。3.语义推测题。根据第三段第一句To find out whether anyone could really learn so many languages, Mr. Erard set out to find Modern Mezzofantis. （为了弄清楚是否真的有人能学会这么多语言，埃拉尔开始寻找现代的Mezzofantis。），和第三段最后一句tried and tested exemplars are few（通过验证的例子很少），表明Erard的调查目的起码有些成效，故C选项“似乎有回报”正确。A选项“都不是很有成效”：在这过程中Erard遇到很多有趣的人，做了一些测试，得到一些结果。B
