She got out to open a metal gate that blocked her path.Thats when she heard the whistle sounded by the driver of a train. Her Renault Clio was parked across a railway line. Seconds later, she watched the train drag her car almost a kilometre down the railway tracks. Ceelys near_miss made the news because she blamed it on the GPS (导航仪). She had never driven the route before. It was dark and raining heavily. Ceely was relying on her GPS, but it made no mention of the crossing. “I put my complete trust in the device and it led me right into the path of a speeding train，” she told the BBC.Who is to blame here? Rick Stevenson, who tells Ceelys story in his book When Machines Fail Us, points the finger at the limitations of technology. We put our faith in digital devices, he says, but our digital helpers are too often not up to the job. They are filled with small problems. And its not just GPS devices: Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless keyboards. The problem with his argument in the book is that its not clear why he only focuses on digital technology, while there may be a number of other possible causes. A mapmaker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. Perhaps the railway authorities are at fault for poor singalling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the GPS equipment. But Stevenson doesnt say.Its a problem that runs through the book. In a section on cars, Stevenson gives an account of the advanced techniques that criminals use to defeat computerbased locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. He says that once again not all new locks have proved reliable. Perhaps, but maybe its also due to the shortage of policemen on the streets. Or changing social circumstances. Or some combination of these factors. The game between humans and their smart devices is amusing and complex. It is shaped by economics and psychology and the cultures we live in. Somewhere in the mix of those forces there may be a way for a wiser use of technology. If there is such a way, it should involve more than just an awareness of the shortcomings of our machines. After all, we have lived with them for thousands of years. They have probably been fooling us for just as long. 【语篇解读】作者在文中讲述了Ceely的GPS出现错误而引发的事故，提到了Rick Stevenson的观点，作者对他的观点提出了不同的意见，从而揭示了人类与科技之间的关系。36What did Paula Ceely think was the cause of her accident? AShe was not familiar with the road. BIt was dark and raining heavily then. CThe railway workers failed to give the signal. DHer GPS device didnt tell her about the crossing.答案D细节理解题。根据第二段中的Ceely was relying on her GPS，but it made no mention of the crossing.可知D项正确。 37.The phrase “near miss” (Paragraph 2) can best be replaced by_. Aclose hitBheavy lossCnarrow escapeDbig mistake答案C词义猜测题。根据第一段的描述可知，Ceely没在车上，所以有She watched the train drag her car almost a kilometre down the railway tracks.因此Ceely当时是“幸运逃脱”的，故C项正确。38Which of the following would Rick Stevenson most probably agree with? AModern technology is what we cant live without. BDigital technology often falls short of our expectation. CDigital devices are more reliable than they used to be. DGPS error is not the only cause for Ceelys accident.答案B推理判断题。根据文章第三段的描述，我们可以知道：我们的数字仪器经常达不到工作的要求，所以，B项应为Rick Stevenson的态度。 39.In the writers opinion, Stevensons argument is _. AonesidedBreasonableCpuzzlingD. wellbased答案A细节理解题。根据第四段中的The problem with his argument in the book is that its not clear why he only focuses on digital technology, while there may be a number of other possible causes.可知作者认为Stevenson的观点是片面的，所以A项正确。 BWhy should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked. Perhaps the best answer lies in our genetic makeup(基因构成)as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible. Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects. Exploration also allows minerals and other potential(潜在的)resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spinoffs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even nonstick pans and mirrored sunglasses are byproducts(副产品)of technological developments in the space industry! While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist. While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future. 【语篇解读】人类为什么要进行太空探索？随着这一问题的提出，作者从人类天性的角度深入剖析了人类进行太空探索的动机以及从中获得的益处太空探索可以帮助我们避免地球上潜在的一些问题。 40Why does the author mention the questions in Paragraph 1? ATo express his doubts. BTo compare different ideas. CTo introduce points for discussion. DTo describe the conditions on Earth. 答案C 推理判断题，是对作者写作目的和意图的推断。作者提出这些问题是为了引出下文要讨论的观点，故选C。 41What is the reason for exploring space based on Paragraph 2? AHumans are natureborn to do so. BHumans have the tendency to fight.CHumans may find new sources of food. DHumans dont like to stay in the same place. 答案A细节理解题。由第二段第一句话Perhaps the best answer lies in our genetic makeup(基因构成)as human beings.和此段最后一句Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.可知A项正确。 42.The underlined word “spinoffs” in Paragraph 4 probably refers to_. Asurvival chances Bpotential resources Cunexpected benefitsDphysical possessions答案C词义猜测题。由第四段中的We have already benefited from other spinoffs including improvements in earthquake prediction，in satellites for weather forecasting and in communications systems. 可推出，此处spinoffs意为“意想不到的好处”。survival chances 生存机会；potential resources潜在的资源；unexpected benefits意想不到的好处；physical possessions物质财产。故选C。 43.What makes it possible for humans to live on other planets? AOur genetic makeup. BResources on the earth. CThe adaptive ability of humans. DByproducts in space exploration.答案C细节理解题。由倒数第二段最后一句Without the ability to reach out across space, the chance to save ourselves might not exist.和最后一段中的It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.可以得出人类的适应能力使得人类居住在其他星球成为可能。 CResearchers in Britain are driving the environmental movement to a whole new level. A team from the University of Warwick has built what it calls the worlds first completely environmentally friendly Formula Three racing car. The car is made mainly of sustainable and renewable materials, like plants and vegetables. The structure around the car is made from natural plant fibers and potatoes. The steering wheel is made from root vegetables like carrots. The engine uses biofuel made from vegetable oil and waste chocolate.The new race car is extremely fast. The car has a top speed of two hundred fifteen kilometers an hour. And it can go from zero to ninetyfive kilometers an hour in just two and one half seconds. The race car meets all of the Formula Three racing requirements except for its biodiesel(生质柴油) engine.The car resulted from the efforts of the University of Warwicks Manufacturing Group and the Warwick Innovative Manufacturing Research Center. They developed the car because of criticism of the racing industry.Automobile racing is one of the most widely watched sports in the world. But it also is considered one of the least friendly to the environment. Race cars burn a lot of fuel, and create a lot of air pollution.In recent years, the racing industry has taken steps to protect the environment. More racing companies are now producing cars that use less energy. These cars produce less pollution than vehicles that depend on traditional fuels, like gasoline.Last year, two American government agencies and an international organization announced a number of policies for environmentallyfriendly racing. They are known as the Green Racing Protocols(协议)The two agencies are the United States Department of Energy and the Environmental Protection Agency. The organization SAE International represents engineers and technical experts in the transportation industry. Officials from the American Le Mans Series also were involved in the effort.The American Le Mans Series became the first racing event to use the protocols in its Green Challenge competition. The race was held in October of last year.Last month, the World First Formula Three racing car was set to run in its first competitive race at the Formula Three Championship Final at Brands Hatch. It would have been the first biodieselpowered car to race at Formula Three.Current Formula Three rules let only gasolinepowered cars compete. Officials needed permission from all of the other Formula Three racers for the biodiesel World First car to compete. They were unable to contact one of the drivers, so the World First car was barred from the event.In test runs, the World First car was the fifth fastest among Formula Three race cars. Supporters are hoping to have the fuel issue resolved in time to compete next season.【语篇解读】英国研究者使环境保护再上一个新台阶：最近他们研制出一款新型的节能环保赛车，这种赛车的速度丝毫不逊色于传统赛车。44Which of the following can be used to describe the new racing car?AEcofriendly, energyconserving, gasolinepowered.BBiodieselpowered, fast, environmentallyfriendly.CFast, easilydamaged, intelligent.DGreen, fast，costeffective.答案B推理判断题。根据文章内容可知，这种新型的赛车靠生质柴油驱动，速度快且有利于环保。故选B项。45The underlined word “barred” in the passage can be replaced by “_” .AdestroyedBforbiddenCsavedDexcused答案B词义猜测题。根据所在的语境判断，如果这种赛车想要参赛必须得到其他所有参赛运动员的许可，而他们无法和其中的一名参赛选手取得联系，所以这辆车最终被禁止参赛。46Which of the following statements is TRUE according to the passage?AThe new racing car was built by Britain and America jointly.BThe new racing car is made completely from sustainable and renewable materials.CThe Green Racing Protocols are aimed at reducing pollution. DThe new racing car was the first biodieselpowered car to race at Formula Three.答案C细节理解题。根据文章第六段和第七段的内容可知，这一协议旨在让赛车
