Part III Reading Comprehension (40 minutes)Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Question 26 to 35 are based on the following passage.Many European countries have been making the shift to electric vehicles and Germany has just stated that they plan to ban the sale of vehicles using gasoline and diesel as fuel by 2030. The country is also planning to reduce its carbon footprint by 80-95% by 2050, ___26___ a shift to green energy in the country. Effectively, the ban will include the registration of new cars in the country as they will not allow any gasoline ___27___ vehicle to be registered after 2030.Part of the reason this ban is being discussed and ___28___ is because energy officials see that they will not reach their emissions goals by 2050 if they do not ___29___ a large portion of vehicle emissions. The country is still ___30___ that it will meet its emissions goals, like reducing emissions by 40% by 2020, but the ___31___ of electric cars in the country has not occurred as fast as expected.Other efforts to increase the use of electric vehicles include plans to build over 1 million hybrid and electric car battery charging stations across the country. By 2030, Germany plans on having over 6 million charging stations ___32___. According to the International Business Times, electric car sales are expected to increase as V olkswagen is still recovering from its emissions scandal.There are ___33___ around 155,000 registered hybrid and electric vehicles on German roads, dwarfed by the 45 million gasoline and diesel cars driving there now. As countries continue setting goals of reducing emissions, greater steps need to be taken to have a ___34___ effect on the surrounding environment. While the efforts are certainly not ___35___, the results of such bans will likely only start to be seen by generations down the line, bettering the world for the future.A) acceptance I) incidentallyB) currently J) installedC) disrupting K) noticeableD) eliminate L) poweredE) exhaust M) restorationF) futile N) skepticalG) hopeful O) sparkingH) implementedSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from 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 the corresponding letter on Answer Sheet 2.Apple’s Stance Highlights a More Confrontational Teach IndustryA) The battle between Apple and law enforcement officials over unlocking a terrorist’s smartphone is the culmination of a slow turning of the tables between the technology industry and the United States government.B) After revelations by the former National Security Agency contractor Edward J. Snowden in 2013 that the government both cozied up to (讨好) certain tech companies and hacked into others to gain access to private data on an enormous scale, tech giants began to recognize the United States government as a hostile actor. But if the confrontation has crystallized in this latest battle, it may already be heading toward a predictable conclusion: In the long run, the tech companies are destined to emerge victorious.C) It may not seem that way at the moment. On the one side, you have the United States government’s mighty legal and security apparatus fighting for data of the most sympathetic sort: the secrets buried in a dead mass murderer’s phone. The action stems from a federal court order issued on Tuesday requiring Apple to help the Federal Bureau of Investigation (F.B.I) to unlock an iPhone used by one of the two attackers who killed 14 people in San Bernardino, California, in December.D) In the other corner i s the world’s most valuable company, whose chief executive, Timothy D. Cook, has said he will appeal the court’s order. Apple argues that it is fighting to preserve a principle that most of us who are addicted to our smartphones can defend: Weaken a single iPhone so that its contents can be viewed by the American government and you risk weakening all iPhones for any government intruder, anywhere.E) There will probably be months of legal tussling, and it is not at all clear which side will prevail in court, nor in the battle for public opinion and legislative favor. Yet underlying all of this is a simple dynamic: Apple, Google, Facebook and other companies hold most of the cards in this confrontation. They have our data, and their businesses depend on the global public’s collective belief that they will do everything they can to protect that data.F) Any crack in that front could be fatal for tech companies that must operate worldwide. If Apple is forced to open up an iPhone for an American law enforcement investigation, what is to prevent it from doing so for a request from the Chinese or the Iranians? If Apple is forced to write code that lets the F.B.I. get into the Phone 5c used by Syed Rizwan Farook, the male attacker in the San Bernardino attack, who would be responsible if some hacker got hold of that code and broke into its other devices?G) Apple’s stance on these issues emerged post-Snowden, when the company started putting in place a series of technologies that, by default, make use of encrypti on to limit access to people’s data. More than that, Apple - and, in different ways, other tech companies, including Google, Facebook, Twitter and Microsoft - have made their opposition to the government’s claims a point of corporate pride.H) Appl’s eme rging global brand is privacy; it has staked its corporate reputation, not to mention the investment of considerable technical and financial resources, on limiting the sort of mass surveillance that was uncovered by Mr. Snowden. So now, for many cases involving governmental intrusions into data, once-lonely privacy advocates find themselves fighting alongside the most powerful company in the world.I) “A comparison point is in the 1990s battles over encryption,” said Kurt Opsahl, general counsel of the El ectronic Frontier Foundation, a privacy watchdog group. “Then you had a few companies involved, but not one of the largest companies in the world coming out with a lengthy and impassioned post, like we saw yesterday from Tim Cook. Its profile has really be en raised.”J) Apple and other tech companies hold another ace: the technical means to keep making their devices more and more inaccessible. Note that Apple’s public opposition to the government’s request is itself a hindrance to mass government intrusio n. And to get at the contents of a single iPhone, the government says it needs a court order and Apple’s help to writenew code; in earlier versions of the iPhone, ones that were created before Apple found religion on (热衷于) privacy, the F.B.I. may have been able to break into the device by itself.K) You can expect that noose (束缚) to continue to tighten. Experts said that whether or not Apple loses this specific case, measures that it could put into place in the future will almost certainly be able to fur ther limit the government’s reach.L) That’s not to say that the outcome of the San Bernardino case is insignificant. As Apple and several security experts have argued, an order compelling Apple to write software that gives the F.B.I. access to the iPhone in question would establish an unsettling precedent. The order essentially asks Apple to hack its own devices, and once it is in place, the precedent could be used to justify law enforcement efforts to get around encryption technologies in other investigations far removed from national security threats.M) Once armed with a method for gaining access to iPhones, the government could ask to use it proactively (先发制人地), before a suspected terrorist attack - leaving Apple in a bind as to whether to comply or risk an attack and suffer a public-relations nightmare. “This is a brand-new salvo in the war against encryption,” Mr. Opsahl said. “We’ve had plenty of debates in Congress and the media over whether the government should have a backdoor, and this is an end run around that - here they come with an order to create that backdoor.”N) Yet it’s worth noting that even if Apple ultimately loses this case, it has plenty of technical means to close a backdoor over time. “If they’re anywhere near worth their salt as engineers, I bet they’re rethinking their threat model as we speak,” said Jonathan Zdziarski, a digital forensic expert who studies the iPhone and its vulnerabilities.O) One relatively simple fix, Mr. Zdziarski said, would be for Apple to modify future versions of the iPhone to require a user to enter a passcode before the phone will accept the sort of modified operating system that the F.B.I. wants Apple to create. That way, Apple could not unilaterally introduce a code that weakens the iPhone — a user would have to consent to it.P) “Nothing is 100 percent hacker-proof,”Mr. Zdziarski said, but he pointed out that the judge’s order in this case required Apple to provide “reasonable security assistance” to unlock Mr. Farook’s phone. If Apple alters t he security model of future iPhones so that even its own engineers’ “reasonable assistance” will not be able to crack a given device when compelled by the government, a precedent set in this case might lose its lasting force. In other words, even if the F.B.I. wins this case, in the long run, it loses.36. It is a popular belief that tech companies are committed to protecting their customers’ private data.37. The US government believes that its access to people’s iPhones could be used to prevent terrorist attacks.38. A federal court asked Apple to help the FBI access data in a terrorist’s iPhone.39. Privacy advocates now have Apple fighting alongside them against government access to personal data.40. Snowden revealed that the American government had tried hard to access private data in massive scale.41. The FBI might have been able to access private data in earlier iPhones without Apple’s help.42. After the Snowden incident, Apple made clear its position to counter government intrusion into personal data by means of encryption.43. According to one digital expert, no iPhone can be entirely free from hacking.44. Timothy Cook’s long web post has helped enhance Apple’s image.45. Apple’s CEO has decided to appeal the federal court’s order to unlock a user’s iPhone.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestion 46 to 50 are based on the following passage.At the base of a mountain in Tanzania’s Gregory Rift,Lake Natron burns bright red, surrounded by the remains ofanimals that were unfortunate enough to fall into the salty water. Bats, swallows and more are chemically preserved in the pose in which they perished, sealed in the deposits of sodium carbonate in the water. The lake’s landscape is bizarre and deadly- and made even more so by the fact that it’s the place where nearly 75percent of the world’s flamingos(火烈鸟) are born.The water is so corrosive that it can burn the skin and eyes of unadapted animals. Flamingos, however, are the only species that actually makes life in the midst of all that death. Once every three or four years, when conditions are right, the lake is covered with the pink birds as they stop flight to breed. Three –quarters of the world’s flamingo s fly over from other salt lakes in the Rift Valley and nest on salt- crystal islands that appear when the water is at specific level- too high and the birds can’t build their nests, too low and predators can more briskly across the lake bed and attack. Wh en the water hits the right level. The baby birds are kept safe form predators by a corrosive ditch.“Flamingos have evolved very leathery skin on their legs so they can tolerate the salt water,” says David Harper, a professor at the University of Leices ter. “ Humans cannot, and would die if their legs were exposed for any length of time.” So far this year, water levels have been too high for the flamingos to nest.Some fish, too, have had limited success vacationing at the lake as less salty lagoons (泻湖) form on the outer edges from hot springs flowing into Lake Natron. Three species of tilapia (罗非鱼) thrive there part-time. “Fish have a refuge in the streams and can expand into the lagoons when the lake is low and the lagoons are separate,” Harper said.“All the lagoons join when the lake is high and fish must retreat to their stream refuges or die.” Otherwise, no fish are able to survive in the naturally toxic lake.This unique ecosystem may soon be under pressure. The Tanzanian government has once again started mining the lake for soda ash, used for making chemicals, glass and detergents. Although the planned operation will be located more than 40 miles away, drawing the soda ash in through pipelines, conservationists worry it could still upset the natural water cycle and breeding grounds. For now, though, life prevails – even in a lake that kills almost everything it touches.46. What can we learn about Lake Natron?A) It is simply uninhabitable for most animals.B) It remains little known to the outside world.C) It is a breeding ground for a variety of birds.D) It makes an ideal habitat for lots of predators.47. Flamingos nest only when the lake water is at a specific level so that their babies can ______.A) find safe shelter more easily C) stay away from predatorsB) grow thick feathers on their feet D) get accustomed to the salty water48. Flamingos in the Rift Valley are unique in that _______.A) they can move swiftly across lagoons C) they breed naturally in corrosive ditchesB) they can survive well in salty water D) they know where and when to nest49. Why can certain species of tilapia sometimes survive around Lake Natron?A) They can take refuge in the less salty waters.B) They can flee quick enough from predators.C) They can move freely from lagoon to lagoon.D) They can stand the heat of the spring water.50. What may be the consequence of Tanzanian government’s planned operation?A) The accelerated extinction of flamingos.B) The change of flamingos’ migration route.C) The overmining of Lake Natron’s soda ash.D) The disruption of Lake Natron’s ecosystem.Passage TwoQuestions 51 to 55 are based on the following passage.It is the season for some frantic last-minute math across the country, employees of all stripe are counting backward in an attempt to figure out just how much paid time-off they have left it their reserves. More of them, though, will skip those calculations altogether and just power through the holidays into 2017: More than h alf of American workers don’t use up all of their allotted vacation days each year.Not so long ago, people would have turned up their noses at that kind of dedication to the job. As marketing professors Silvia Bellezza, Neeru Paharia, and Anat Keinan recently explained in Harvard Business Review (HBR), leisure time was once seen as an indicator of high social status, something attainable only for those at the top. Since the middle of the 20th century, though, things have turned the opposite way – these days, punishing hours at your desk, rather than days off, are seen as the mark of someone important.In a series of several experiments, the researchers illustrated just how much we’ve come to admire busyness, or at least the appearance of it. Volunteers read two passages, on about a man who led a life of leisure and another about a man who was over-worked and over –scheduled; when asked to determine which of the two had a higher social status, the majority of the participants said the latter. The same held true for people who used products that implied they were short on time: In one experiment, for example, customers of the grocery-delivery service Peapod were seen as of higher status than people who shopped at grocery stores that were equally expensive; in another, people wearing wireless headphones were considered further up on the social ladder than those wearing regular headphones, even when both were just used to listen to music.In part, the authors wrote in HBR, this pattern may have to do with the way work itself has changed over the past several decades.We think that the shift from leisure-as-status to busyness-as-status may be linked to the development of knowledge-intensive economics. In such economies, individuals who possess the human capital characteristics that employers or clients value(e.g., competence and ambition) are expected to be in high demand and short supply on the job market. Thus, by telling others that we are busy and working all the time, we are implicitly suggesting that we are sought after, which enhances our perceived status.Even if you feel tempted to sacrifice your own vacation days for fake busyness, though, at least consider leaving your weekends unscheduled. It’s for your own good.51. What do most employees plan to do towards the end of the year?A) Go for a vacation. C) Set an objective for next year.B) Keep on working. D) Review the year’s achievements.52.How would people view dedication to work in the past?A) They would regard it as a matter of course.B) They would consider it a must for success.C) They would look upon it with contempt.D) They would deem it a trick of businessmen.53. What did the researchers find through a series of experiments?A) The busier one appears, the more respect one earns.B) The more one works, the more one feels exploited.C) The more knowledge one has, the more competent one will be.D) The higher one’s status, the more vacation time one will enjoy.54. What may account for the change of people’s attitude to wards being busy?A) The fast pace of life in modern society.B) The fierce competition in the job market.C) The widespread use of computer technology.D) The role of knowledge in modern economy.55. What does the author advise us to do at the end of the passage ?A) Schedule our time properly for efficiency.B) Plan our weekends in a meaningful way.C) Plan time to relax however busy we are.D) Avoid appearing busy when we are not.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

More of them, though, will skip those calculations altogether and just power. . . . through the holidays into 2017: More than half of American workers don’t use up all of their allotted vacation days each year.Not so long ago, people would have turned up their noses at that kind of dedication to the job. As marketing professors Silvia Bellezza, Neeru Paharia, and Anat Keinan recently explained in69. . . .2017年12月大学英语六级考试真题（第三套）Harvard Business Review (HBR), leisure time was once seen as an indicator of high social status, something attainable only for those at the top. Since the middle of the 20th century, though, things have turned the opposite way – these days, punishing hours at your desk, rather than days off, areseen as the mark of someone important.In a series of several experiments, the researchers i llustrated just how much we’ve come to admire busyness, or at least the appearance of it. Volunteers read two passages, on about a manwho led a life of leisure and another about a man who was over-worked and over –scheduled;when asked to determine which of the two had a higher social status, the majority of theparticipants said the latter. The same held true for people who used products that implied theywere short on time: In one experiment, for example, customers of the grocery-delivery servicePeapod were seen as of higher status than people who shopped at grocery stores that were equally expensive; in another, people wearing wireless headphones were considered further up on thesocial ladder than those wearing regular headphones, even when both were just used to listen to music.In part,the authors wrote in HBR.this pattern may have to do with the way work itself has changed over the past several decades.We think that the shift from leisure-as-status to business-as-status may be linked to the development of knowledge-intensive economics. In such economies,individuals who possess the human capital characteristics that employers or clients value (petence and ambition) are expected to be in high demand and short supply on the job market.Thus，by telling others that weare busy and working all the time, we are implicitly suggesting that we are sought after, which enhances our perceived status.Even if you feel tempted to sacrifice your own vacation days for fake busyness, though, atleast consider leaving your weekends unscheduled.It's for your own good.51. What do most employees plan to do towards the end of the year?A) Go for a vacation.B) Keep on working. C) Set an objective for next year.D) Review the year’s achievements.52.How would people view dedication to work in the past?. . . .A) They would regard it as a matter of course.B) They would consider it a must for success.70. . . .2017年12月大学英语六级考试真题（第三套）C) They would look upon it with contempt.D) They would deem it a trick of businessmen.53.

Part III Reading Comprehension (40 minutes) Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage・ Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresp on ding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Many European countries have been making the shift to electric vehicles and Germany has just stated that they plan to ban the sale of vehicles using gasoline and diesel as fuel by 2030. The coun try is also planning to reduce its carb on footprint by 80-95% by 2050, 26 a shift to green energy in the country. Effectively, the ban will in elude the regist ration of new cars in the country as they will not allow any gasoline 27 vehicle to be registered after 2030.Part of the reason this ban is being discussed and 28 is because energy officials see that they will not reach their emissions goals by 2050 if they do not 29 a large portion of vehicle emissions. The country is still 30 that it will meet its emissions goals, like reducing emissions by 40% by 2020, but the 31 of electric cars in the country has not occurred as fast as ejected.Other efforts to in crease the use of electric vehicles in elude plans to build over 1million hybrid and electric car battery changing stations across the country. By 2030, Germany plans on having over 6 million charging stations 32 . According to the In ter national Business Times, electric car sales are expected to increase as Volkswagen is still recovering from its emissions seandal.There are 33 around 155,000 registered hybrid and electric vehicles on German roads, dwarfed by the 45 million gasoline and diesel cars driving there now. As countries continue setting goals of reducing emissions, greater steps need to be taken to have a 34 effect on the surrounding environment. While the efforts are certainly not 35 , the results of such bans will likely only start to be seen by generations down the line, bettering the world for the future.A)acceptanee B) currently C) disrupting D) eliminate E) exhaust F) futile G) hopeful H) implemented I) incidentally J) installed K) noticeable L) powered M) restoration N) skeptical O) sparkingSection BDirections: In this sectior\ you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from 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 the corresponding letter on Answer Sheet 2.Apple's Stance Highlights a More Confrontational Tech Industry[A]The battle between Apple and law enforcement officials over unlocking a terrorist's smartphone is the culmination of a slow turning of the tables between the technology industry and the United States government・[B]After revelati ons by the former Nati onal Security Agency con tractor Edward J. Snowden in 2013 that the government both cozied up to (讨好)certain tech companies and hacked into others to gain access to private data on an enormous scale, techgiants began to recognize the United States government as a hostile actor・ But if the confrontation has crystallized in this latest battle, it may already be heading toward a predictable conclusion: In the long run, the tech companies are destined to emerge victorious.[C]It may not seem that way at the moment. On the one side, you have the United States government's mighty legal and security apparatus fighting for data of the most sympathetic sort: the secrets buried in a dead mass murderers phone. The action steins from a federal court order issued on Tuesday requiring Apple to help the Federal Bureau of Investigation (FBI) to unlock on iPhone used by one of the two attackerswho killed 14 people in San Bernardino, California, in December.[D]In the other corner is the world's most valuable compan* whose chief executive, Timothy Cook, has said he will appeal the court's order. Apple argues that it is fighting to preserve a principle that most of us who are addicted to our smartphones can defend: Weaken a single iPhone so that its contents can be viewed by the American government and you risk weakening all iPhones for any gover nment in truder, any where.[E]There will probably be mon ths of legal confrontati on, and it is not at all clear which side will prevail in court, nor in the battle for public opinion and legislative favor.Yet underlying all of this is a simple dynamic: Apple, Google, Facebook and other companies hold most of the cards in this confrontation. They have our data, and their businesses depend on the global public f s collective belief that they will do everything they con to protect that data.[F]Any crack in that front could be fatal for tech companies that must operate worldwide. If Apple is forced to open up an iPhone for an American law enforce me nt investigation, what is to preve nt it from doing so for a request from the Russia ns or the Ira nians? If Apple is for ced to write code that lets the FBI get into the Phone 5c used by Syed Rizwan Farook, the male attacker in the San Bernardino attack, who would be responsible if some hacker got hold of that code and broke into its other devices?[G]Apple's stance on these issues emerged post-Snowden, when the company started putting in place a series of technologies that, by default, make use of en crypti on （加密）to limit access to people's data ・ More tha n that, Apple—a nd, in different ways, other tech companies, including Google, Facebook, Twitter and Microsoft—have made their opposition to the government's claims a point of corporate pride・[H]Apple's emerging global brand is privacy; it has staked its corporate reputati on, not to men tion the in vestment of considerable tech nical and financial resources, on limiting the sort of mass surveillance that was uncovered by Mr. Snowden. So now, for many cases involving governmental intrusions into data, once-lonely privacy advocates find themselves fighting alongside the most powerful company in the world.[I]U A comparison point is in the 1990s battles over encryption/ said Kurt Opsahl, general counsel of the Electronic Frontier Foundatior\ a privacy watchdog group. n Then you had a few companies involved, but not one of the largest compa nies in the world comi ng out with a lengthy and impassi oned post, like we saw yesterday from Timothy Cook. Its profile has really been raised.H[J]Apple and oilier tech companies hold another ace: the technical means to keep making their devices more and more inaccessible. Note that Apple's public opposition to the governmerit's request is itself a hindrance to mass government intrusion. And to get at the contents of a single iPhone, the government says it needs a court order and Apple's help to write new code; in earlier versions of the iPhone, ones that were created before Apple found religion on （热衷于）privacy, the FBI might have been able to break into the device by itself.[K]You can expect that noose （束缚）to continue to tighten・ Experts said that whether or not Apple loses this specific case, measures that it could put into place in the future will almost certainly be able to further limit the government's reach.[L]That is not to say that the outcome of the San Bernardino case is insignificant. As apple and several security experts have argued, an order compelling Apple to write software that gives the FBI access to the iPhone in questi on would establish an unsettli ng precede nt. The order esse ntially asks Apple to hack its own devices, and once it is in place, the pr ecede nt could be used to justify law enforcement efforts to get around encryption technologies in other investigations far removed from national security threats.[M]Once aimed with a method for gaining access to iPhones, the government couldask to use it proactively （先发制人地），before a suspected terrorist attack—leaving Apple in a bind as to whether to comply or risk an attack and suffer a public-relations nightmare. H This is a brand new move in the war against encryptioMr. Opsahl said.H We have had plenty of debates inCongress and the media over whether the government should have a backdoor, and this is an end run （迂回战术）around that—here they come with an order to create that backdoor."[N]Yet it is worth noting that even if Apple ultimately loses this case, it has plenty of tech nical means to close a backdoor over time. H If they are any where near worth their salt as engineeI bet they are rethinking their threat model as we speak,n said Jonathan Zdziarski, a digital expert who studies the iPhone and its vulnerabilities. [O]One relatively simple fix, Mr. Zdziarski said, would be for Apple to modify future versions of the iPhone to require a user to enter a passcode before the phone will accept the sort of modified operating system that the FBI wants Apple to create. That way, Apple could not unilaterally introduce a code that weakens the iPhone—a user would have to consent to it.[P]"Nothing is 100 percent hacker-proof," Mr. Zdziarski said, but he pointed out that the judge's order in this case required Apple to provide "reas on able security assistance'1 to unlock Mr. Farook's phone. If Apple alters the security model of future iPh ones so that even its own en gineers* H reas on able assistance11 will not be able to crack a given device when compelled by the government, a precedent set in this case might lose its lasting force. In other words, even if the FBI wins this case, in the long run z it loses.36.It is a popular belief that tech companies are committed to protecting their customers* private data.37.The US government believes that its access to people's iPhones could be used to prevent terrorist attacks.38.A federal court asked Apple to help the FBI access data in a terrorist's iPhone.39.Privacy advocates now have Apple fighting alongside them against government access to personal data.40.Snowden revealed that the American government had tried hard to access private data on a massive scale.41.The FBI might have been able to access private data in earlier iPhones without Apple's help・42.After the Snowden incident, Apple made clear its position to counter government intrusion into personal data by means of encryption.43.According to one digital expert, no iPhone can be entirely free from hacking.44.Timothy Cook's long web post has helped enhance Apple's image.45.Apple's CEO has decided to appeal the federal court's order to unlock a user!s iPhone.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A）, B）, C） and D）. You should decide on the best choice and mark the corresp onding letter on An swer Sheet 2 with a single line through the cen tre.Passage OneQuestions 46 to 50 are based on the following passage.At the base of a moun tain in Tanzania's Gregory Rift, Lake Natr on bur ns bright red, surrotinded by the remains of animals that were unfortunate enough to fall into the salty water. Bats, swallows and more are chemically preserved in the pose in which they perished, sealed in the deposits of sodium carb on ate in the water. The lake's Ion dscape is bizarre and deadly—a nd made eve n more so by the fact that it's the place where nearly 75 percent of the world's flamingos （火烈鸟）are born.The water is so corrosive that it can bum the skin and eyes of unadapted animals. Flamingos『however, are the only species that actually makes life in the midst of all that death. Once every three or four years, when conditions are right, the lake is covered with the pink birds as they stop flight to breed.Three・quarters of the world's flamingos fly over from other salt lakes in the Rift Valley and nest on salt-crystal islands that appear when the water is at a specific level—too high and the birds can't build their nests, too low and predators can move briskly across the lake bed and attack. When the water hits the right level, the baby birds are kept safe from predators by a corrosive ditch."Flamingos have evolved very leathery skin on their legs so they can tolerate the salt water," says David Harper, a professor at the University of Leicester・,f Humans carmot, and would die if their legs were exposed for any length of time.1' So far this year,water levels have been too high for the flamingos to nest. Some fish, too, have had limited success vacationing at the lake as less salty lagoons （泻1胡）form on the outer edges from hot springs flowing into Lake Natron. Three species of tilapia （罗鱼）thrive there part-time. "Fish have a refuge in the streams and can expand into the Iagoons when the lake is low and the Iagoons are separate,H Harper said. "All the Iagoons join when the lake is high and fish must retreat to their stream refuges or die.1' Otherwise, no fish are able to survive in the naturally toxic lake.This unique ecosystem may soon be under pressure. The Tanzanian government has once again started mining the lake for soda ash, used for making chemicals, glass and detergents. Although the planned operation will be located more than 40 miles away, drawing the soda ash in through pipelines, conservationists worry it could still upsetthe natural water cycle and breeding grounds. For now, though, life prevails—even in a lake that kills almost everything it touches.46.What can we learn about Lake Natron?A)It is simply uninhabitable for most animals.B)It remains little known to the outside world.C)It is a breeding ground for a variety of birds.D)It makes an ideal habitat for lots of predators.47.Flamingos nest only when the lake water is at a specific level so that their babies can .A)find safe shelter more easilyB)grow thick feathers on their feetC)stay away from predatorsD)get accustomed to the salty water48.Flamingos in the Rift Valley are unique in that .A)they can move swiftly across IagoonsB)they can survive well in salty waterC)they breed naturally in corrosive ditchesD)they know where and when to nest49.Why can certain species of tilapia sometimes survive around Lake Natron?A)They can take refuge in the less salty waters・B)They can flee quick eno ugh from predators.C)They can move freely from lagoon to Iago on.D)They can stand the heat of the spring water.50.What may be the consequence of Tanzanian governmenfs planned operation?A)The accelerated extinotion of flamingos.B)The change of flamingos* migration route.C)The overmining of Lake Natron^ soda ash.D)The disruption of Lake Natron's ecosystem.Passage TwoQuestions 51 to 55 are based on the following passage.It is the seas on for some frantic last-mi nute math—ac ross the coun try, employees of all stripes are counting backward in an attempt to figure out just how much paid time-off they have left in their reserves.

For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a “disease.”On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.“It unties the hands of the pharmaceutical(制药的)industry so that they can begin treating the disease and not just the side effects,”he said.“Right now, people think of aging as natural and something you can’t control,”he said. “IN academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.”But if aging were recognized as a disease, he said,“It would attract funding and change the way we do health care. What matters is understand that aging is curable.”“It was always known that the body accumulates damage,”he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions.”Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespancan be increased, which some researchers suggest is possible. Hayflick is not among them.“There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,”Hayflick said.“Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years.”46. Whatdo people generally believe about aging?A) It should cause not alarm whatsoever.B) They just cannot do anything about it.C) It should be regardedas a kind of disease.D) They can delay it with advances in science.47.How do many scientists view aging now?A) It might be prevented and treated. C) It results from a vitamin deficiency.B) It can be as risky as heart disease. D) It is an irreversible biological process.48.

Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring(指导), and have better odds of being hired. Studies show they’re also perceived as more competent than women in STEM (Science, Technology, Engineering, and Mathematics) fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too.“Say, you know, this is the best student I’ve ever had,” says Kuheli Dutt, a social scientist and diversity officer at Columbia University’s Lamont campus. “Compare those excellent letters with a merely good letter: ‘The candidate was productive, or inte lligent, or a solid scientist or something that’s clearly solid praise,’ but nothing that singles out the candidate as exceptional or one of a kind.”Dutt and her colleagues studied more than 1,200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared withtheir male counterparts. That includes letters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt says they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than out-standing letters of recommendation.“We're not trying to assign blame or criticize anyone or call anyone consciously sexist. Rather, the point is to use the results of this study toopen upmeaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level.”Which may lead to some recommendations for the letter writers themselves.51. What do we learn about applicants to postdoctoral positions in geosciences?A)There are many more men applying than women.B)Chances for women to get the positions are scarce.C)More males than females are likely to get outstanding letters of recommendation.D)Male applicants have more interest in these positions than their female counterparts.52. What do studies about men and women in scientific research show?A) Women engaged in postdoctoralwork are quickly catching up.B) Fewer women are applying for postdoctoralpositions due to gender bias.C) Men are believed to be better able to excel in STEM disciplines.D) Women who are keenly interested in STEM fields are often exceptional.53. What do the studies find about the recommendation letters for women applicants?A) They are hardly ever supported by concrete examples.B) They contain nothing that distinguishes the applicants.C) They provide objective information without exaggeration.D) They are often filled with praise for exceptional applicants.54. What did Dutt and her colleagues do with the more than 1,200 letters of recommendation?A) They asked unbiased scholars to evaluate them.B) They invited women professionals to edit them.C) They assigned them randomly to reviewers.D) They deleted all information about gender.55. What does Dutt aim to do with her study?A) Raise recommendation writers’awareness of gender bias in their letters.B) Open up fresh avenues for women post-doctors to join in reaserach work.C) Alert women researchers to all types of gender bias in the STEM disciplines.D) Start a public discussion on how to raise women’s status in academic circles.Part Ⅳ Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

You should decide on the best choice and mark the corresponding letter on Answer Sheet 2with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a “disease.”On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.“It unties the hands of the pharmaceutical(制药的)industry so that they can begin treating the disease and not just the side effects,”he said.“Right now, people think of aging as natural and something you can’t control,”he said. “IN academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.”But if aging were recognized as a disease, he said,“It would attract funding and change the way we do health care. What matters is understand that aging is curable.”“It was always known that the body accumulates damage,”he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions.”Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespancan be increased, which some researchers suggest is possible. Hayflick is not among them.“There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,”Hayflick said.“Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years.”46. Whatdo people generally believe about aging?A) It should cause not alarm whatsoever.B) They just cannot do anything about it.C) It should be regardedas a kind of disease.D) They can delay it with advances in science.47.How do many scientists view aging now?A) It might be prevented and treated. C) It results from a vitamin deficiency.B) It can be as risky as heart disease. D) It is an irreversible biological process.48. What does Alex Zhavoronkov think of “describing aging as a disease”?A) It will prompt people to take aging more seriously.B) It will greatly help reduce the side effects of aging.C) It will free pharmacists from the conventional beliefs about aging.D) It will motivate doctors and pharmacists to find ways to treat aging.49. What do we learn about the medical community?A) They now have a strong interest in research on aging.B) They differ from the academic circles in their view on aging.C) They can contribute to people’s health only to a limited extent.D) They have ways to intervene in people’s aging process.50. What does Professor Leonard Hayflick believe?A) The human lifespan cannot be prolonged.B) Aging is hardly separable from disease.C) Few people can live up to the age of 92.D) Heart disease is the major cause of aging.Passage TwoQuestions 51 to 55 are based on the following passage.Female applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts.

2017年12月六级部分真题参考答案(完整版)Part Ⅰ WritingBe Generous with Your HelpWhen it comes to the topic of help, we are frequently told that,"Help others, and you will be helped when you are in need. '' Simple as the sa ying is, it implies the importance of helping others in need. What I learn from the remark, in short words, is that helping others is helping yourself. Examples can easily be found to make this point clearer. The story of the ant and the dove is a case in point. An ant slipped into the river when drinking alo ng the river. A dove heard his cries for help and threw him a leaf, which helpe d the ant float back to the bank. After a few days, a hunter was raising his g un to the dove as she was building her nest. Seeing this, the ant ran quickly t o bite the hunter's leg. The dove heard the hunter's scream and flew away. All in all, this example indicates that when we offer our help to others, we are leaving a way open for the future. Helping others is a virtue, and we should take some measures to carry forward this virtue and do others a favor. Only in this way can we build a loving and harmonious society.Part Ⅱ Listening Comprehension说明：由于2017年12月六级考试全国共考了2套听力，本套真题听力与前2套内容完全一样，只是顺序不一样。

"Nearly everyone i know is addicted in some measure to the internet, "wrote tony Schwartz in The New York Times. it's a common complaint these days. A steady stream of similar headlines accuse the net and its offspring apps, social media sites and online games of addicting us to distractionB. There's little doubt that nearly everyone who comes in contact with the net has difficulty concentration than it takes to post a status update. as one person ironically put it in the comments section of Schwartz'sonline article, "As I was reading this very excellent article.I stopped at least half a dozen times to cheek my email.C. There's something different about this technology: it is both invasive and persuasive.but who's at fault for its overuse ？To find solutions, it's important to understand whatwe ' re dealing with.There are four parties conspiring to keep you connected the tech,your boss, your friends and you.D. The technologies themselves and their makers, are the easiest suspects to blame for our diminishing attention spans. Nicholas Carr,author of The Shallows ：what the internet is doing Our brains, wrote, The net is designed to be an interruption system, a machine geared to dividing attention.E. Online services like Facebook, twitter and the like, are called out ofmanipula-tion--making ，products so good that people can't stop using them. afterstudying these products for several years, I wrote a book about how they do it. I learnedit all starts with the business model. since these services rely on advertising revenue, The more frequentlyyou use money they make.It teams of people focused on engineering their services to be as engaging as possible. these products aren't habit-forming by chance; it's by design.' s no wminpdaenr itehseseemcpoloy they have an incentive to keep us hooked.F. However, as good as these services are, there are simple steps we can take to keepthem at bay.For example, we can change how often we receive the distracting notifications that trigger our urge to check.According to adam marchick, ceo of mobile marketing company kahuna, less than 15 percentof smartphone users ever bother to adjust their notification setlings--meaning the remaining 85 percent of us default to the app makers' every preset trigger.Google and Apple have made it far too difficult to adjust these settings so it's up to us to take steps ensure we set these triggers to suit our own needs, not the needs of the app makers.G.While companies like Facebook harvest attention to generate revenue fromadvertisers, other technologies have no such agenda. take email, for example. this system couldn't care less how often you use it. Yet t o many, email is the mosthabit-forming medium of all.We check email at all hours of the day--we're obsessed, butwhy? Because that's what the boss wants.For almost all white-collar jobs, A slowResponse to a message could hurt not only your reputation but also your livelihood.H. Your friends are also responsible.Think about this familiar scene.People gathered around a table,enjoying food and each others company. there's laughter and a bit of kidding. Then, during an interval in the conversation, someone takes out their phone to check who knows what.Barely anyone notices and no one says a thing.I. Now imagine the same dinner,but instead of checking their phone, the person belches（打嗝）-loudly.Everyone notices. unless the meal takes place in a beer house, this is considered bad manners. The impolite act violates the basic rules of etiquette. one has to wonder why don ' t we apply the same social norms to checking phones during meals,meetings and conversations as we do to other antisocial behaviors somehow, we accept it and say nothingwhen someone offends.J. The reality is taking one's phone out at the wrong time is worse than belching because, unlike other minoroffense, checking tech is contagious. once one person looks at their phone,other people feel compelled to dothe same, starting a chain reaction. the more people are on their phones, the fewer people are talking untilfinally you are the only one left not reading email or checking twitter. from a societal perspective, phonechecking is less like belching in public and more like another bad habit. our phones are like cigarettes-something to do when were bored or when our fingers need something to toy with seeing others enjoy asmoke,or sneak a quick glance, is too tempting to resist and soon everyone is doing it.K.

W hite-collar workers check email round the clock because it is required by their employersSection 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 paragraph from which theinformation is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.who's really addicting you to Technology?A. "Nearly everyone i know is addicted in some measure to the internet, "wrote tony Schwartz in The New York Times. it's a common complaint these days. A steady stream of similar headlines accuse the net and its offspring apps, social media sites and online games of addicting us to distractionB. There's little doubt that nearly everyone who comes in contact with the net has difficulty concentration than it takes to post a status update. as one person ironically put it in the comments section of Schwartz's online article, "As I was reading this very excellent article.I stopped at least half a dozen times to cheek my email.C. There's something different about this technology: it is both invasive and persuasive. but who's at fault for its overuse ？To find solutions, it's important to understand whatwe ' re dealing with.There are four parties conspiring to keep you connected the tech, your boss, your friends and you.D. The technologies themselves and their makers, are the easiest suspects to blame for our diminishing attention spans. Nicholas Carr,author of The Shallows ：what theinternet is doing Our brains, wrote, The net is designed to be an interruption system, a machine geared to dividing attention.E. Online services like Facebook, twitter and the like, are called out of manipula-tion--making ，products so good that people can't stop using them.after studying these products for several years, I wrote a book about how they do it. I learned it all starts with the business model. since these services rely on advertising revenue, The more frequently you use money they make.It ' s no winder these companies employ teams of people focused on engineering their services to be as engaging as possible.these products aren't habit-forming by chance; it's by design. they have an incentive to keep us hooked.F. However, as good as these services are, there are simple steps we can take to keep them at bay.For example, we can change how often we receive the distracting notifications that trigger our urge tocheck.According to adam marchick, ceo of mobile marketing company kahuna, less than 15 percent of smartphone users ever bother to adjust their notification setlings--meaning the remaining 85 percent of us default to the app makers' every preset trigger.Google and Apple have made it far too difficult to adjust these settings so it's up to us to take steps ensure we set these triggers to suit our own needs, not the needs of the app makers.G.While companies like Facebook harvest attention to generate revenue from advertisers, other technologies have no such agenda. take email, for example. this system couldn't care less how often you use it. Yet t o many, email is the mosthabit-forming medium of all.We check email at all hours of the day--we're obsessed, butwhy? Because that's what the boss wants.For almost all white-collar jobs, A slowResponse to a message could hurt not only your reputation but also your livelihood.H. Your friends are also responsible.Think about this familiar scene.People gathered around a table, enjoying food and each others company. there's laughter and a bit of kidding. Then, during an interval in the conversation, someone takes out their phone to check who knows what.Barely anyone notices and no one says a thing.I. Now imagine the same dinner,but instead of checking their phone, the personbelches（打嗝）-loudly.Everyone notices. unless the meal takes place in a beer house, this is considered bad manners. The impolite act violates the basic rules of etiquette. one hasto wonder why don ' t we apply the sameciasol norms to checking phones during meals,meetings and conversations as we do to other antisocial behaviors somehow, we accept it and say nothing when someone offends.J. The reality is taking one's phone out at the wrong time is worse than belching because, unlike other minor offense, checking tech is contagious. once one person looks at their phone,other people feel compelled to do the same, starting a chain reaction. the more people are on their phones, the fewer people are talking until finally you are the only one left not reading email or checking twitter. from a societal perspective, phone checking is less like belching in public and more like another bad habit. our phones are like cigarettes-something to do when were bored or when our fingers need something to toy with seeing others enjoy a smoke,or sneak a quick glance, is too tempting to resist and soon everyone is doing it.K. The technology, your boss, and your friends, all influence how often you find yourself using (or overusing )these gadgets. but there's still someone who deserves scrutiny--the person holding the phone. L. I have a confession. even though i study habit-forming technology for a living, disconnecting is not easy for me.I'm online far more than I'd like like Schwartz and so many others, I often find myself distracted and off tack.I wanted to know why so i began self-monitoring to try to understand my behavior. that's when i discovered an uncomfortable truth. i use technology as an escape. when I'm doing something I'd rathernot do, or when I'm someplace I'd rather not attention was often a good thing, like whenpassing time on public transportation, but frequently my tech use was not so benign. when i faced difficult work, like thinking through an article idea or editing the same draft for the hundredth time, for example, a more sinister screen would draw me in. i could easily escape discomfort.temporarlly.by answering email orbrowsing ing the web under the pretense of so-called"research.

2017年12月大学英语六级考试真题（第三套）Part III Reading Comprehension （40 minutes）Section AQuestions 26 to 35 are based on the following passage.Many European countries have been making the shift to electric vehicles and Germany has just stated that they plan to ban the sales of vehicles using gasoline and diesel as fuel by 2030. The country is also planning to reduce its carbon footprint by 80-95% by 2050, ___26___ a shift to green energy in the country. Effectively, the ban will include the registration of new cars in the country as they will not allow any gasoline ___27___ vehicle to be registered after 2030.Part of the reason this ban is being discussed and ___28___ is because energy officials see that they will not reach their emissions goals by 2050 if they do not ___29___ a large portion of vehicle emissions. The country is still ___30___ that it will meet its emissions goals, like reducing emissions by 40% by 2020, but the ___31___ of electric cars in the country has not occurred as fast as expected.Other efforts to increase the use of electric vehicles include plans to build over 1 million hybrid and electric car battery charging stations across the country. By 2030, Germany plans on having over 6 million charging stations ___32___. According to the International Business Times, electric car sales are expected to increase as Volkswagen is still recovering from its emissions scandal.There are ___33___ around 155,000 registered hybrid and electric vehicles on German roads, dwarfed by the 45 million gasoline and diesel cars driving there now. As countries continue setting goals of reducing emissions, greater steps need to be taken to have a ___34___ effect on the surrounding environment. While the efforts are certainly not ___35___, the results of such bans will likely only start to be seen by generations down the line, bettering the world for the future.注意：此部分试题请在答题卡2上作答。

2017年12月英语六级真题及答案完整版（第三套）【5】Section cPassage oneQuestions 46 to 50 are based on the following passage.In the beginning of the movie / robot a robot has to decide whom to save after two cars plunge into the water-del spooner or a child. even though spooner screams"save her save her.the robot rescues him because it calculates that he has a 45 percent chance of survival compared to sarah's ll percent. the robots decision and its calculated approach raise an important question:would humans make the same choice and which choice would we want our robotic counterparts to make?Isaac asimov evaded the whole notion of morality in devising his three laws of robotics, which hoId that I. robots cannot harm humans or allow humans to come to harm; 2. robots must obey preservation, unless doing so conflicts with laws i or 2. these laws are programmed into Asimov's robots--they don't have to think, judge, or value. they don t have to like humans or believe that hurting them is wrong or bad. they simply don't do it.The robot who rescues Spooner's life in i, robot follows Asimov's zero law: robots cannot harm humanity (as opposed to individual humans or allow humanity to come to harm--an expan-sion of the first law that allows robots to determine what's in the greater good. under the first law.a robot could not harm a dangerous gunman, but under the zero" law, a robot could kill the gunman to save others.Whether it’s possible to program a robot with saf eguards such as asimov's laws is debatable A word such as"harm"is vague (what about emotional harm? is replacing a human employeeharm?)and abstract concepts present coding problems. the robots in asime complications and loopholes in the three laws, and even when the laws work, robots still have to asscss situations.Assessing situations can be complicated. a robot has to identify the players, conditions, and possible outcomes for warious scennrios. It’s doubtful that a computer program can do that-at least, not without some undesirable results. A robotocost at the bristol robotics laboratory programmed a robot to save human proxies(替身)called“H’bots”from danger. when one H-bot of headed for danger,the robot sucecssfully pushed it out the way. but when two h-bots became imperiled, the robot choked 42 percent of the time, unable to decide which to save and letting them both die .The robot choked 42 percent of the time, unable to decide which to save and letting them headed for danger, the robot successfully pushed it.how can a robot decide whom to save or what’s best for humanity, especially if it can't calculate survival odds?46. what question does the example in the movie raise?a whether robots can reach better decisionsb)whether robots follow Asimov’s zero’lawc)how robots may make bad judgmentsd) how robots should be programmed47. what does the author think of asimov's three laws of robotics?a) they are apparently divorced from realityb) they did not follow the coding system of roboticsc) they laid a solid foundation for robotics.d) they did not take moral issues into consideration.48. what does the author say about asimov s robots?a they know what is good or bad for human beingsb)they are programmed not to hurt human beingsc) they perform duties in their owners'best interest.d) they stop working when a moral issue is involved.49. what does the author want to say by mentioning the word"harm"in asimovs laws?a abstract concepts are hard to program.b) it is hard for robots to make decisions.c) robots may do harm in certain situations.d) laws use too many vague terms.50. what has the roboticist at the bristol robotics laboratory found in his experiment?a)robots can be made as intelingent as human beiegs some day.b)robots can have moral issues encoded into their programs.c)robots can have trouble making decisions in complex scenarios.d)robots can be programmed to perceive potential perils.Passage TwoQuestions 5i to 55 are based on the following passage.Our world now moves so fast that we seldom stop to see just how far we have come in just a few years.The lasest iPhone6s,for example,has a dual-core processor and fits nicely into your pocket.by comparison, you would expect to find a technological specification like this on your standard laptop in an office anywhere in the world.It’s no wonder that device we buy has a plug on the end of it or a wireless connection to internet soon.our current smartphone lifestyle will expand to create our own smart homelifestyle too.All researches agree that close to 25 billion devices.things and sensors will be connnected by 2020 which incidentally is also the moment that Millennias(千禧一代)are expected to make up 75 percent of our overall workforce, and the fully connected home become a reality for large numbers of people worldwide.However,this is just the tip of the provebial iceberg as smart buildings and even cities incrasimgly become the norm as leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation coupled with intelligent energy and facilities managemen.Online security cameras, intelligent lighting and a wealth of sensors that control both tempera ture and air quality are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a business or managing a large building.We can expect that the ever-growing list of devices, systems and environments remain connected,always online and talking to each other. the big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities.The good news is that most of this technology is already invented. let's face it, it wasn't too long ago that the idea of working from anywhere and at anytime was some form of adistant wtopim(乌托邦式的) dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.It's time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.51. what does the example of iphone 6s serve to show?A)The buge capacity of the smartphones people now use.B) the widespread use of smartphones all over the worldc)the huge impact of new technology on people, everyday lifed) the rapid technological progress in a very short period of time52. what can we expect to see by the year 2020?A)apps for the internet of thingsB)The popularization of smart homesc)the emergence of millennialsD)total globalization of the word53. what will business owners do when they become aware of the benefits of the internet of things?A)employ fewer workers in their operationB)gain automatic control of their businessesC)invest in more smart buildings and citiesD)embrace whatever new technology there is54.What is the most exciting challenge when we possess more and more data?A)How to turn it to profitable useB)how to do real time data analysisC) how to link the actionable systems.D) how to devise new ways to store it55. what does the author think about working from anywhere and at anytime?A)it is feasible with a connection to the internetB) it will

2017年12月大学英语六级真题及答案解析（全三套）六级听力第一套：Section AConversation 1M: And now, for the lighter side of the news, Europe is setting an example for the rest of the world when it comes to food waste.W: That’s right John. This week the Italian government pass legislation that aims to dramatically reduce the amount of food wasted in the country. New laws have been put into place that would make it easier for farms and supermarkets to donate unsold foods to those who are in need.M: Yes. And in addition to this, businesses would now be rewarded for successful efforts to cut food waste.W: Italy is not the only country to focus on reducing food waste. Just earlier this year, the European Parliament voted in favor of legislation that would stop grocery giants from unfair trading practices that result in overproduction, thus creating waste.M: In France, the government has banned supermarkets from throwing away edible foods and imposed harsh penalties on businesses that fail to comply with the regulations.W: While there is still much progress to be made, other countries could learn a thing or two from the example set by France and Italy. In the United States, up to forty percent of all food goes uneaten. Despite the fact that one in seven American households lacks regular access to good food, one major cause of this problem is the confusion over food expiration labels, which are currently not regulated by the government.M: All this could change soon. This wave of new laws in Europe will definitely put more pressure on law makers to reduce food waste here. We turn now to a spokesperson from Harvard University’s Food Law and Policy Clinic for more on the story. And now, let’s welcome Prof. Edward Becker to speak to us.Q1: What does the woman say about the new laws in Italy?Q2: What did the European Parliament do reduce food waste?Q3: What has the French government done recently?Q4: What is the major cause of food waste in the United States?Q1. C) They facilitate the donation of unsold foods to the needy.Q2. B) It passed a law aiming to stop overproduction.Q3. D) It has banned supermarkets from dumping edible foods.Q4. A) The confusion over food expiration labels.Conversation 2M: Thank you for calling Saks Fifth Avenue department store. How can I be of assistance to you today?W: Hello. I was in your store this past weekend and bought a few items. Yesterday, my friend told me that the annual anniversary sales had begun. It turned out she bought the same sweater as I did but for a much lower price.M: Yes. Our anniversary sale started on Monday. We do offer price adjustments within seven days of purchase to ensure our customer satisfaction. You said you did the purchase here this past weekend?W: Yes. I was shopping in your store last Sunday afternoon.M: That would definitely fall within the price adjustment window. Do you have an account with us? We can credit your account directly with the difference if you wish. Otherwise we can send a gift card by mail if you prefer.W: Crediting my account would be wonderful. Thank you. Now that you mention there's a sale going on, I do remember a dress I quite like when I was in the shop on Sunday. Is it on offer as well?M: Yes, ma'am. All the new arrivals are 15-20% off. In addition to the sale, we're running a promotion for complimentary tailoring if you need it.W: That's a good news. The dress really caught my eye but I did have some concerns about the length. How long will the alterations take?M: Our tailoring department guarantees alterations to be completed within five working days. If you like I can set one aside for you. If you're able to come this afternoon, you can give your name to the sale manager and they will be able to assist you.Q5. What do we learn about Saks department store?Q6. What does the man say Saks department store offers?Q7. What does the woman want the store to do to address the price difference?Q8. What is the service Saks department store offers in addition to the promotional sale?Q5. B) It has just launched its annual anniversary sales.Q6. D) Price adjustments within seven days of purchase.Q7. C) Credit it to her account.Q8. D) Complimentary tailoring.Section BPassage 1Barbie dolls have a particular look to them. They’re thin, tall, long-legged and virtually unlike any real human being. Although over the years Barbie has had more than 180 different careers-including football coach, sign language teacher, ambassador, president and astronaut–her body shape hasn’t changed much.Last year Mattel, the company that makes Barbie dolls, added some Barbies to its line that have different skin tones and hair textures. There are now Barbies with one of seven skin tones, 22 eye colours and 24 hair styles to choose from. Last year Mattel also gave Barbie a flat foot, rather than forcing her to be “in heels” all the time like the original Barbie is.Now they are introducing new Barbies with three slightly different body shapes while the original, tall and thin Barbies will continue to be sold.In a statement on its website, the company says it wants Barbies to look more like real people, and to give girls everywhere infinitely more ways to spark their imagination and play out their stories.Although many people say the new Barbies are a step in the right direction, some people say they don’t go far enough. They say that the new body shapes could be even more different from the original, tall, thin Barbies.Sales of Barbie dolls have been falling “every year since 2012,” according to CBC News.The toys aren’t in stores yet but they will be sold online at the Barbie website, starting this week, for $9.99.Q9. What do we know about the original Barbie dolls?Q10. Why do some people feel unsatisfied with the new Barbie dolls?Q11. Where will the new Barbie dolls be sold first?Q9. A. They are thin, tall, and unlike real human beings.Q10. D. Their body shapes have not changed much.Q11. C. On the Internet.Passage 2The earliest printed book we know today appeared in China in the year 868, and metal type was in use in Korea at the beginning of the fifteenth century, but it was in Germany around the year 1450 that a printing press using movable metal type was invented.Capitalism turned printing from an invention into an industry. Right from the start, book printing and publishing were organized on capitalist lines. 'The biggest sixteenth- century printer, Plantin of Antwerp, had twenty-four printing presses and employed more than a hundred workers. Only a small fraction of the population was literate, but the production of books grew at an extraordinary speed. By 1500 some twenty million volumes had already been printed.The immediate effect of printing was to increase the circulation of works that were already popular in the handwritten form, while less popular works went out of circulation. Publishers were interested only in books that would sell fairly quickly in sufficient numbers to cover the costs of production and make a profit. Thus, while printing enormously increased access to books by making cheap, high-volume production possible, it also reduced choice.The great cultural impact of printing was that it facilitated the growth of national languages. Most early books were printed in Latin, but the market for Latin was limited, and in its pursuit of larger markets the book trade soon produced translations into the national languages emerging at the time. Printingindeed played a key role in standardizing and stabilizing these languages by fixing them in print, and producing dictionaries and grammar books.Q12. What happened in Germany around the year of 1450?Q13. What does the speaker say about the printer, Plantin of Antwerp?Q14. What was the immediate effect of printing?Q15. What was the great cultural impact of printing?Q12. A) Movable metal type began to be used in printing.Q13. B) It was the biggest printer in the 16th century.Q14. B) It boosted the circulation of popular works.Q15. D) It promoted the growth of national languages.Section CRecording OneYou dream about being a movie star. You live in a big house in Hollywood, go to the Oscars every year, and win. You will be rich and famous. Wait a minute. You also hate having your photos taken and you are very shy. So how could you ever become a movie star? Choosing a right career can be hard. Many people graduate from school or college not knowing what they want to do with their lives and get a job without really thinking about it. For some, things work out fine. But others often find themselves stuck in a job they hate. Your working life lasts in average 40 years, so it’s important to find a job you like and feel enthusiastic about.Luckily, there are many ways you can get help to do this. The Australian website WWW. Careers online. com, compares choosing a career with going to the movies. Before you see a movie, you find out what films are showing. The site suggests you should do the same with your career. Find out what jobs are available and what your options are. Next, decide which movie you like best. If you are not a romantic person, you won’t want to see a love story. In other words, with yourcareer, you should decide which job will suit your personality. Finally, decide how to get movie tickets and find out where the theater is before you go. With your career, you need to find information about where you can work and how to get a job in that profession.So, how do you start? Begin by asking yourself some questions, certain life experiences. Have you travelled overseas? Do you have any extra certificates at your degree? Such as the first aid license, for example. Your physical state and build can also affect which jobs you can do. A person, for example, who is allergic to cats will probably never become an animal doctor. Flight attendants, firefighters and police officers have to be over a certain height and be physically fit. Your personality matters too. Are you outgoing or shy? If you like working alone, a job that requires lots of team work might not suit you.Choosing a career can take time and a lot of thought. However, when you know you can look forward to working in your dream job, you will be glad you thought it through.16. What does the speaker say about many college graduates?17. What does the Australia website suggest you do first to find a suitable job?18. What should you think about when you look for the right job according to the Australian website?16.D) They choose a job without thinking it through.17.B) Find out what job choices are available.18.A) The qualifications you have.Recording 2Kwanzaa is a cultural festival, during which African-American celebrate and reflect upon their rich heritage as the products of the two worlds. It begins December 26th and last for seven days. Kwanzaa was founded in 1966 by Dr. Karenga, a college professor and African-American leader, who believed that a special holiday could help African Americans meet their goals of building strong families,learning about their history and creating a sense of unity. After conducting extensive research in which he studied the festivals of many African groups of people, he decided that the new holiday should be a harvest or first fruit’s celebration. In cooperating ideas from many different harvest traditions. Kwanzaa is a … word meaning the first fruits of the harvest. The east African language of … was chosen as an official language of Kwanzaa. Because it is a non-tribal language spoken by a large portion of the African population. Also its pronunciation is easy. Kwanzaa is based on seven principles which are unity, self-determination, collective work and responsibility, cooperative economics, purpose, creativity and faith. One principal is highlighted each day of the holiday. In preparation for the celebration, a astroy matters placed on the table. Along with the candle holder was seven candles.

Right from the start, bookprinting and publishing were organized on capitalist lines. 'The biggest sixteenth- centuryprinter, Plantin of Antwerp, had twenty-four printing presses and employed more than ahundred workers. Only a small fraction of the population was literate, but the production ofbooks grew at an extraordinary speed. By 1500 some twenty million volumes had alreadybeen printed.The immediate effect of printing was to increase the circulation of works that were alreadypopular in the handwritten form, while less popular works went out of circulation. Publishers were interested only in books that would sell fairly quickly in sufficient numbersto cover the costs of production and make a profit. Thus, while printing enormously increased access to books by making cheap, high-volume production possible, it also reduced choice.The great cultural impact of printing was that it facilitated the growth of national languages.Most early books were printed in Latin, but the market for Latin was limited, and in its pursuit of larger markets the book trade soon produced translations into the national languages emerging at the time. Printing indeed played a key role in standardizing andstabilizing these languages by fixing them in print, and producing dictionaries and grammar books.Q12. What happened in Germany around the year of 1450?Q13. What does the speaker say about the printer, Plantin of Antwerp?Q14. What was the immediate effect of printing?Q15.

"creating this sanctuary is a bold move that the people of Palau recognise as 31 to our survival. we want to lead the way in restoring the health of the ocean for future generations.Palau has only been an 32 nation for twenty years and has a strong history of environmen-tal protection.it is home to one of the worlds finest marine ecosystems, with more than 1, 300 species of fish and 700 species of coral.Senator Hokkons Baules lead 33- of the Palau National marine sanctuary act, said the sanctuary willhelp build a 34 future for the palauan people by honoring the conservation traditions of our past". these include the centuries-old custom of"", where leaders would call a temporary stop to fishing for key species in order to give fish 35 an opportunity to replenish（补充）.A）allocate I)permitB）celebrities J)secureC）commercial K)solitaryD）communities L)spectacleE）essential M)sponsorF）exclusive N)stocksG）independent O)territoryH）indulgeSection BDirections: in this section, you an going to read a passage with ten statements attached to it each statement contains information given in ine of the paragraphs.identify theparagraph from 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 the correspanding letter on answer sheet 2Data sharing: an open mind on open data[A] it is a movement building steady momentum: a call to make research data, software code and experimental metbods publicly availablc and transparent A spirit of openness is gaining acceptance in the science community, and is the only way, say advocates, to address a'crisis in science whereby too few findings are successfully reproduced. furthermore, they say, it is the best way for researchers to gather the range of observations that are necessary to speed up discoveries or to identify large-scale trends[b] the open-data shift poses a confusing problem for junior researchers,on the one hand, the drive to share is gathering official steam. since 2013, global scientific bodies have begun to that support increased public access to research on the other hand, scientists disagree about how much and when they should share data, and they debate whether sharing it is more likely to accelerate science and make it more robust, or to introduce vulnerabilities andproblems. as more joumals and funders adopt data-sharing requirements, and as a growing number of enthusiasts call for more openness.junior researchers must find their place between adopters and those who continue to hold out, even as they strive to launch their own careers.( c) one key challenge facing young scientists is how to be open without becoming scientifically vulnerable. they must determine the risk of jeopardizing a job offer or a collaboration proposal from those who are wary of -or unfamiliar with -open science. and they must learn how to capitalize on the movements benefits, such as opportunities for more citations and a way to build a reputation without the need for conventional metrics, such as publication in high-impact journals.[D] some fields have embraced open data more than others. researchers in psychology, a field rocked by findings of irreproducibility in the past few years, have been especially vocal supporters of the drive for more-open science. a few psychology journals have created incentives to increaseinterest in reproducible science-for example, by affixing an" badge to articles that clearly state where data are available. according to social psychologist brian nosek,executive director of the center for open science, the average data-sharing rate for the joumal Psychological science, which uses the badges, increased tenfold to 38% from 2013 to 2015.[E] funders, too, are increasingly adopting an open-data policy several strongly encourage,and some require a data-management plan that makes data available. the ional scienc Foundation is among these. some philanthropic(&)funders, including the bill &melinda Gates foundation in seattle, washington, and the wellcome trust in london, also mandate open data from their grant recipients.[F] but many young rescarchers,especially those who have not been mentored in open science are uncertain about whether to share or to stay private. graduate students and who often are working on their lab heads grant, may have no choice if their supervisor or another senior colleague opposes sharing.[G] some fear that the potential impact of sharing is too high, especially at the early stages of a career "Everybody has a story about soneone getting scooped"says New York university astronomer david hogg. those fears may be a factor in a lingering hesitation to share data even when publishing in journals that mandate it.[H] researchers at small labs or at institutions focused on teaching arguably have the most to lose.when sharing hard-won data. "with my institution and teaching load, i don't have postdocs and grad students, "says terry mcglynn, a tropical biologist at california stateuniversity,Dominguez hills. "the stakes are higher for me to share data because it's a bigger fraction of what's happening in my lab."[I] researchers also point to the time sink that is involved in preparing data for others to view Once the data and associated materials appear in a repository( 存储库), answering questions and handling complaints can take many hour.[J] the time investment can present other problems. in some cases, says data scientist karthik Ram, it may be difficult for junior researchers to embrace openness when senior colleagues many of whom head selection and promotion committees-might ridicule what they may view as misplaced energies i have heard this recently that embracing the idea of open data and code makes traditional academics uncomfortable, "says ram. "the concem seems to be that open advocates don't spend their time being as productive as possible[K]an open-science stance can also add complexity to a collaboration. kate ratliff, who studies social attitudes at the university of florida, gainesville, says that it can seem as if there are two camps in a field-those who care about open science and those who don't " there is a new area to navigate-"are you cool with the fact that i'll want to make the data open?'-when talking with somebody about an interesting research idea, she says.[L] despite complications and concerns, the upsides of sharing can be significant. for example, when information is uploaded to a repository, a digital object identifier(DOI) is assigned.Scientists can use a doi to publish each step of the research life cycle, not just the final paper In so doing, they can potentially get three citations- one each for tthe data and software,inaddition to the paper itself. and although some say that citations for software or data hacelittle currency in academia, they can have other benefits[M]many advocates think that transparent data procedures with a date and time stamp will protect ientists from being scooped. "this is the sweet spot between sharing and getting credit for it.while discouraging plagiarism says lvo Grigorov a project cooedinator at thenational institute of aquatic resources research secretariat in charlottenlund, denmark. hogg.says that scooping is less of a problem than many think. "the two cases i'm familiar with didn't involve open data or code, "he says.[N] open science also offers junor researchers the chance to level the playing field by gaining better access to crucial data .rose mounce a postdoc studing ecolutionary biology atthe University of cambridge, uk, is a vocal champion of open science, partly because his fossilbased research depends on access to others' data. he says that more openness in science could help to discourage what some perceive as a common practice of shutting out early-career scientists requests for data.[[O]communication also helps for those who worry about jeopardizing a collaboration, he says Concems about open science should be discussed at the outset of a study. ""whenever you start a project with someone, you have to establish a clear understanding of expectations for who owns the data, at what point they go public and who can do what with them, "he says.[P] in the end, sharing data, software and materials with colleagues can help an early-career researcher to gain recognition-a crucial component of success. the thing you are searching for is reputation," says titus brown, a genomics(基因组学) researcher at the university of California, davis."to get grants and jobs, you have to be relevant and achieve some level of public recognition. anything you do that advances your presence - especially in a larger sphere, outside the communities you know-is a net win."36. astronomer david hogg doesn't think scooping is as serious a problem as generally thought.37. some researchers are hesitant to make their data public for fear that others might publish nething similar before them.38.some psychology journals have offered incentives to encourage authors to share their data39. there is a growing demand in the science community that research data be open to the public40. sharing data offers carly career researchers the chance to build a certain level of reputation.41.data sharing enables scientists to publish each step of their research work, thus leading to more citations.42. scientists hold different opinions about the extent and timing of data sharing43. potential problems related to data sharing should be made known to and discussed by all participants at the beginning of a joint research project44. sharing data and handling data-related issues can be time-consuming45. junior researchers may have no say when it comes to sharing dataSection cPassage oneQuestions 46 to 50 are based on the following passage.In the beginning of the movie / robot a robot has to decide whom to save after two cars plunge into the water-del spooner or a child. even though spooner screams"save her save her.the robot rescues him because it calculates that he has a 45 percent chance of survival compared to sarah's ll percent. the robots decision and its calculated approach raise an importantquestion:would humans make the same choice and which choice would we want our robotic counterparts to make?Isaac asimov evaded the whole notion of morality in devising his three laws of robotics, which hoId that I. robots cannot harm humans or allow humans to come to harm; 2. robots must obey preservation, unless doing so conflicts with laws i or 2. these laws are programmed into Asimov's robots--they don't have to think, judge, or value. they don t have to like humans or believe that hurting them is wrong or bad. they simply don't do it.The robot who rescues Spooner's life in i, robot follows Asimov's zero law: robots cannot harm humanity (as opposed to individual humans or allow humanity to come to harm--anexpan-sion of the first law that allows robots to determine what's in the greater good. under the first law.a robot could not harm a dangerous gunman, but under the zero" law, a robot could kill the gunman to save others.Whether it’s possible to program a robot with safeguards such as asimov's laws is debatable A word such as"harm"is vague (what about emotional harm? is replacing a human employee harm?)and abstract concepts present coding problems. the robots in asime complications and loopholes in the three laws, and even when the laws work, robots still have to asscss situations.Assessing situations can be complicated. a robot has to identify the players, conditions, and possible outcomes for warious scennrios. It’s doubtful that a computer program can do that-at least, not without some undesirable results. A robotocost at the bristol robotics laboratory programmed a robot to save human proxies(替身)called“H’bots”from danger. when one H-bot of headed for danger,the robot sucecssfully pushed it out the way. but when two h-bots became imperiled, the robot choked 42 percent of the time, unable to decide which to save and letting them both die .The robot choked 42 percent of the time, unable to decide which to save and letting them headed for danger, the robot successfully pushed it.how can a robot decide whom to save or what’s best for humanity, especially if it can't calculate survi val odds?46. what question does the example in the movie raise?a whether robots can reach better decisionsb)whether robots follow Asimov’s zero’lawc)how robots may make bad judgmentsd) how robots should be programmed47. what does the author think of asimov's three laws of robotics?a) they are apparently divorced from realityb) they did not follow the coding system of roboticsc) they laid a solid foundation for robotics.d) they did not take moral issues into consideration.48. what does the author say about asimov s robots?a they know what is good or bad for human beingsb)they are programmed not to hurt human beingsc) they perform duties in their owners'best interest.d) they stop working when a moral issue is involved.49. what does the author want to say by mentioning the word"harm"in asimovs laws?a abstract concepts are hard to program.b) it is hard for robots to make decisions.c) robots may do harm in certain situations.d) laws use too many vague terms.50. what has the roboticist at the bristol robotics laboratory found in his experiment?a)robots can be made as intelingent as human beiegs some day.b)robots can have moral issues encoded into their programs.c)robots can have trouble making decisions in complex scenarios.d)robots can be programmed to perceive potential perils.Passage TwoQuestions 5i to 55 are based on the following passage.Our world now moves so fast that we seldom stop to see just how far we have come in just a few years.The lasest iPhone6s,for example,has a dual-core processor and fits nicely into your pocket.by comparison, you would expect to find a technological specification like this on your standard laptop in an office anywhere in the world.It’s no w onder that device we buy has a plug on the end of it or a wireless connection to internet soon.our current smartphone lifestyle will expand to create our own smart home lifestyle too.All researches agree that close to 25 billion devices.things and sensors will be connnected by 2020 which incidentally is also the moment that Millennias(千禧一代)are expected to make up 75 percent of our overall workforce, and the fully connected home become a reality for large numbers of people worldwide.However,this is just the tip of the provebial iceberg as smart buildings and even cities incrasimgly become the norm as leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation coupled with intelligent energy and facilities managemen.Online security cameras, intelligent lighting and a wealth of sensors that control both tempera ture and air quality are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a business or managing a large building.We can expect that the ever-growing list of devices, systems and environments remain connected,always online and talking to each other. the big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities.The good news is that most of this technology is already invented. let's face it, it wasn't too long ago that the idea of working from anywhere and at anytime was some form of a distant wtopim(乌托邦式的) dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.It's time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.51. what does the example of iphone 6s serve to show?A)The buge capacity of the smartphones people now use.B) the widespread use of smartphones all over the worldc)the huge impact of new technology on people, everyday lifed) the rapid technological progress in a very short period of time52. what can we expect to see by the year 2020?A)apps for the internet of thingsB)The popularization of smart homesc)the emergence of millennialsD)total globalization of the word53. what will business owners do when they become aware of the benefits of the internet of things?A)employ fewer workers in their operationB)gain automatic control of their businessesC)invest in more smart buildings and citiesD)embrace whatever new technology there is54.What is the most exciting challenge when we possess more and more data?A)How to turn it to profitable useB)how to do real time data analysisC) how to link the actionable systems.D) how to devise new ways to store it55. what does the author think about working from anywhere and at anytime?A)it is feasible with a connection to the internetB) it will thrive in smart buildings, cities and homesC)it is still a distant utopian dream for ordinary workersD) it will deliver tangible benefits to both boss and workerPart IVTranslation (30
