Part III Reading Comprehension (40 minutes) Section ADirections: In this section, there is a passage with ten blanks. You are required to select one wordfor 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 throughthe centre. You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.Many European countries have been making the shift to electric vehicles and Germany hasjust 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 togreen 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 seethat 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 asfast as expected.Other efforts to increase the use of electric vehicles include plans to build over 1 million. . . .63. . . .2017年12月大学英语六级考试真题（第三套）hybrid and electric car battery charging stations across the country. By 2030, Germany plans onhaving 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 banswill likely only start to be seen by generations down the line, bettering the world for the future.A) acceptanceB) currentlyC) disruptingD) eliminate E)exhaustF) futileG) hopefulH) implementedI)incidentallyJ) installedK) noticeableL) poweredM) restorationN) skepticalO) sparkingSection 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.64. . . .2017年12月大学英语六级考试真题（第三套）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 orderissued 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 is the world’s most valuable company, whose chi ef executive, Timothy D. Cook, has said he will appeal the court’s order. Apple argues that it is fighting to preserve aprinciple that most of us who are addicted to our smartphones can defend: Weaken a single iPhoneso that its contents can be viewed by the American government and you risk weakening alliPhones for any government intruder, anywhere.E) There will probably be months of legal tussling, and it is not at all clear which side will prevailin court, nor in the battle for public opinion and legislative favor. Yet underlying all of this is asimple 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 collectivebelief 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 Appleis forced to open up an iPhone for an American law enforcement investigation, what is to preventit from doing so for a request from the Chinese or the Iranians? If Apple is forced to write codethat 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 intoits other devices?G) Apple’s stance on these issues emerged post-Snowden, when the company started putting inplace a series of technologies that, by default, make use of encryption to limit access to people’sdata. 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 pointof corporate pride.H) Apple’s emerging global brand is privacy; it has staked its corp orate reputation, not to mentionthe 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 governmental65. . . .2017年12月大学英语六级考试真题（第三套）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, generalcounsel of the Electronic 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 lengthyand impassioned post, like we s aw yesterday from Tim Cook. The profile has really been raised.”J) Apple and other tech companies hold another ace: the technical means to keep making theirdevices more and more inaccessible. Note that Apple’s public opposition to the government’srequest 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 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 notApple loses this specific case, measures that it could put into place in the future will almostcertainly be able to further limit the government’s reach.L) That’s not to say that the outcome of the San Bernardino case is insignificant. As Apple andseveral security experts have argued, an order compelling Apple to write software that gives theF.B.I. access to the iPhone in question would establish an unsettling precedent. The orderessentially asks Apple to hack its own devices, and once it is in place, the precedent could be usedto 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-newsalvo in the war against encryption,” Mr. Opsahl said.“We’ve had plenty of debates in Congressand the media over whether the government should have a backdoor, and this is an end run aroundthat - 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 bet66. . . .2017年12月大学英语六级考试真题（第三套）they’re rethinking their threat model as we speak,” said Jonathan Zdziarski, a digital forensicexpert who studies the iPhone and its vulnerabilities.O) One relatively simple fix, Mr. Zdziarski said, would be for Apple to modify future versions ofthe 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’sorder in th is case required Apple to provide “reasonable security assistance” to unlock Mr.Farook’s phone. If Apple alters the security model of future iPhones so that even its ownengineers’ “reasonable assistance” will not be able to crack a given device when comp elled by the government, a precedent set in this case might lose its lasting force. In other words, even if theF.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 preventterrorist 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 topersonal data.40. Snowden revealed that the American government had tried hard to access private data inmassive 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). You67. . . .2017年12月大学英语六级考试真题（第三套）should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with asingle 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 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 inthe deposits of sodium carbonate in the water. The lake’s landscape is bizarre and deadly- andmade even more so by the fact that it’s the place where nearly 75percent of the world’sflamingos(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 everythree or four years, when conditions are right, the lake is covered with the pink birds as they stopflight to breed. Three –quarters of the world’s flamingos fly over from other salt lakes in the RiftValley and nest on salt- crystal islands that appear when the water is at specific level- too high andthe birds can’t build their nests, too low and predators can more briskly across the lake bed and attack. When the water hits the right level, the baby birds are kept safe from predators by acorrosive 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. “ Humans cannot, and would die iftheir legs were exposed for any length of time.” So far this year, water levels have bee n too highfor 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 lagoonswhen the lake is low and the lagoons are separate,” Harper said. “All the lagoons join when thelake is high and fish must retreat to their stream refuges or die.” Otherwise, no fish are able tosurvive 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.68. . . .2017年12月大学英语六级考试真题（第三套）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 easilyB)grow thick feathers on their feet C)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 lagoonsB)they can survive well in salty water C)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 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.Questions 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 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. 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 towards 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) Find time to relax however busy we are.D) Avoid appearing busy when we are not.PartⅣTranslation (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 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, one 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 die nts value (e. g. , compete nee 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.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.C)They would look upon it with con tempt.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 ear ns.B)The more one works, the more one feels exploited.C)The more kno wledge one has, the more compete nt 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 towards 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)Find 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.

英语六级真题及答案17年12月3
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。

2017年12月英语六级第三套阅读解析The December 2017 administration of the College English Test (CET-6) in China included a reading comprehension section with three passages and corresponding questions. This essay will provide a detailed analysis of the content and structure of this reading section to help students better prepare for future CET-6 exams.The first passage in the reading section was an informative text about the history and development of the Chinese tea culture. The passage began by tracing the origins of tea cultivation in ancient China, noting that tea has been an integral part of Chinese society for over 2,000 years. It then discussed how tea drinking evolved from a elite pastime to a more widespread cultural phenomenon, as new tea cultivation and preparation techniques were developed over the centuries.The passage highlighted key milestones in the spread of tea culture such as the Tang Dynasty when tea houses became popular gathering places and the Song Dynasty when the practice of tea ceremonies emerged. It also explored how tea cultivation techniqueswere improved to produce higher quality teas that were in high demand both domestically and for international export. Overall, the passage provided a comprehensive overview of the rich history and evolution of tea culture in China.The reading comprehension questions that followed this passage tested students' understanding of the main ideas and supporting details presented. For example, one question asked students to identify the key factors that contributed to the increasing popularity of tea drinking in ancient China. Another question required students to explain the significance of the developments in tea cultivation and preparation techniques during the Song Dynasty. Students needed to carefully read the passage and extract the relevant information to answer these questions accurately.The second passage in the reading section was a argumentative essay discussing the benefits of learning a second language. The passage began by acknowledging the challenges and difficulties that come with learning a new language, but then went on to argue that the advantages of bilingualism far outweigh these difficulties.The key points made in the passage include how learning a second language can enhance cognitive abilities, improve academic performance, and expand career opportunities. The passage cited research studies demonstrating that bilingual individuals tend tohave stronger problem-solving skills, greater mental flexibility, and enhanced memory capacity compared to monolingual individuals. It also discussed how learning a second language can boost academic achievement in various subjects beyond just language arts.In terms of career benefits, the passage highlighted how proficiency in multiple languages makes job candidates more attractive to employers in an increasingly globalized job market. It provided examples of how bilingual employees can serve as valuable cultural and linguistic bridges between companies and their international clients or partners. Overall, the passage made a compelling case for the personal, academic, and professional advantages of becoming bilingual.The reading comprehension questions for this passage assessed students' understanding of the main argument, supporting evidence, and underlying assumptions. For instance, one question asked students to identify the key reasons presented in the passage for why learning a second language is beneficial. Another question required students to recognize the underlying assumption that bilingualism confers cognitive advantages.The third and final passage in the reading section was a descriptive text about the unique architectural features of traditional Japanese houses. The passage began by explaining the historical and culturalcontext that shaped the development of traditional Japanese residential design, noting how it was heavily influenced by principles of Zen Buddhism and Shintoism.The passage then went on to describe in detail the key architectural elements that are characteristic of traditional Japanese houses. This included details about the use of natural materials like wood, paper, and bamboo, the emphasis on open floor plans and flexible spaces, and the incorporation of gardens and outdoor areas. The passage also discussed how traditional Japanese houses were designed to be in harmony with the natural environment and seasonal changes.Additionally, the passage highlighted how certain design features like sliding doors, tatami mats, and low ceilings were intended to promote a sense of tranquility and mindfulness. It explained how these elements reflected the Japanese cultural values of simplicity, functionality, and a deep appreciation for nature. Overall, the passage provided readers with a vivid and insightful description of the unique architectural aesthetics of traditional Japanese homes.The reading comprehension questions for this passage assessed students' understanding of the key architectural elements described, as well as their ability to infer the cultural and philosophical influences that shaped traditional Japanese residential design. For example, one question asked students to identify the specific designfeatures that were intended to create a sense of harmony with nature. Another question required students to explain how certain architectural elements reflected core Japanese cultural values.In conclusion, the reading comprehension section of the December 2017 CET-6 exam featured three diverse passages that tested a range of reading skills. The first passage on Chinese tea culture assessed students' ability to comprehend and synthesize historical information. The second passage on the benefits of bilingualism evaluated students' understanding of an argumentative essay. And the third passage on traditional Japanese houses challenged students to analyze the relationship between architectural design and cultural influences.Overall, this reading section provided a well-rounded assessment of the English reading proficiency of CET-6 test takers. The passages covered a variety of topics and genres, and the corresponding comprehension questions required students to demonstrate skills such as identifying main ideas, interpreting supporting details, and making inferences.

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 thislatest 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 steins from a federal court order issued on Tuesday requiring Apple to help the Federal Bureau of Investigation (FBI) 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 is the world's most valuable company, 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 government intruder, anywhere.[E] There will probably be months of legal confrontation, 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 Russians or the Iranians? If Apple is forced 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 encryption (加密）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] Apple's emerging 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 Electronic 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 Timothy Cook. Its profile has really been raised."[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 government'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 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 aimed 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 move in the war against encryption," Mr. Opsahl said. "We have had plenty of debates in Congress 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 technical means to close a backdoor over time. "If they are anywhere near worth their salt as engineers, I bet they are rethinking their threat model as we speak," 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 mod ify 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 "reasonable security assistance" to unlock Mr. Farook's phone. If Apple alters the 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 FBI 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 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 C 仔细阅读Passage OneQuestions 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 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 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 75 percent 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 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. "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 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 lagoonsB) 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 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 stripes are counting backward in an attempt to figure out just how much paid time-off they have left in their reserves. 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 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, one 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.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.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 towards 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) Find time to relax however busy we are.D) Avoid appearing busy when we are not.Part I Translation (30minutes)Directions：For this part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.洞庭湖位于湖南省东北部，面积很大，但湖水很浅。

2017年12月大学英语六级考试真题答案与详解（第3套）Part I Writing审题思路：“帮助他人”是我们日常生活中非常熟悉的话题。
本文是一篇语句点评类作文，要求我们针对所给引言“帮助他人，你在困难的时候就能获得帮助”给出自己的观点。
首先，考试需要从引言出发，解释内涵，进而将重点放在阐述帮助他人，你在困难的时候就能获得帮助的重要性上，在阐述论点时，既可以分条阐述帮助他人的重要性，也可以采用例证法，使论点鲜活易懂。
高分范文：Be 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 saying 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 along the river.A dove heard his cries for help and threw him a leaf,which helped the ant float back to the bank.After a few days,a hunter was raising his gun to the dove as the was building her nest.Seeing this,the ant ran quickly to 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.全文翻译：不要吝啬你的帮助提到“帮助”这一话题，我们经常被告知，“帮助他人，你在困难的时候就能获得帮助。

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

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.

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.

"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

【参考范文】Mutual Help(1) In ancient times when the environment was harsh and hostile, our ancestors relied on mutual help for survival. Although nowadays people do not necessarily expect help in return when they offer help to others, it is more than likely that they will be helped when difficulties arise.(2) Humans are grateful for others’ help and would repay the favor that someone has done for them. The idiom “you scratch my back, and I’ll scratch yours” is an example in point to show such gratefulness of mankind. Due to such gratitude, we often hear examples that an elderly person is helped by the one he orshe helped many years ago. Such real-life examples confirm me in my belief that those who help will be helped. As people offering help are always considered kind-hearted and generous, it is impossible for a civilized society to leave such good people helpless when they encounter difficulties.(3) Therefore, I hold that those who lend a helping hand to others will get help when they are in trouble.【行文点评】(1) 叙述古代环境恶劣的时候，我们的祖先靠相互帮助为生，引出本文的话题：“助人者人亦助之”。

精选全文完整版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.

They’re thin, tall, long-legged and virtually unlike any real human being. Although over the years Barbie has had more than 180 differentcareers-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. Printing indeed 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 your career, 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 jobsyou 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 firs t 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. One black, three red and three green. The black candle represents the African-American people. The red is fortheir struggles, and the green represents their hopes for their future. Other items placed on our table are a variety of fruit is of comes gifts and communal unity cup for pouring and sharing drinks. Each day of Kwanzaa usually before the evening meal，family and friends gather around the table and someone lights the candle beginning with the black. After that，candles are lit alternatively from left to right. While the candles is being lit, a principal is recited then each person present takes turn to speak about the importance that the principle has to himself or herself. Next, the ceremony focuses on remembering those who've died. A selected person pours water or juice from the unity cup into a bowl. That person then drinks from the cup and raises it high saying “her thanmbi”，which means that let’s all pour together. All repeat “her thanmbi” seven times and each person drinks from the cup . Then they and names of African American leaders and heroes a cold out to and everyone reflects upon the great things these people did. The ceremony is followed by a meal, and then singing and perhaps listening to African music19.What does the speaker say about Kwanzaa?20. For what purpose did Doctor Karenga create the special holiday?21. What does the word Kwanzaa mean?22. What do people do while each candle is being let at the Kwanzaa celebration?19. B)It is a cultural festival founded for African-Americans.20. C)To help African-Americans to realize their goals.21. B)The fruits of the harvest.22. A)They recite a principle.Recording 3The Mediterranean diet is based upon the eating patterns of traditional cultures in the Mediterranean region. Several noted nutritionists in research projects have concluded that this diet is one of the most healthful in the world in terms of preventing such illnesses as heart disease and cancer and increasing life expectancy. The countries that have inspired Mediterranean diet all surround the Mediterranean Sea. These cultures have eating habits that developed over thousands of years. In Europe, parts of Italy, Greece, Portugal, Spain and southern France adhere to principles of the Mediterranean diet as to the morocco, Indonesia, and North Africa. Parts of the Balkan region and turkey follow the diet as well as middle eastern countries like Lebanon and Syria, the Mediterranean region is warm and sunny and produces large supplies of fresh fruits and vegetables almost a year round thatthe people eat many times a day. Wine, bread, all of oil and nuts are other staples of the region. In the Mediterranean sea has historically yielded abundant quantities of fish. International interest in therapeutic qualities of Mediterranean diet began back in the late nineteen fifties. When medical researchers started to link the currency of heart disease with diet, Doctor Ansol Keths performed the epidemiological analysis of diets around the world. In titled of the seven countries study, it is considered one of the greatest studies of its kind ever performed. In it, Keths gathered data on heart disease in its potential causes from nearly thirty thousand men in Greece, Italy, Croatia, Serbia, Japan, Finland, the Netherlands and the United States. The study was conducted over period of decades. It concluded that the Mediterranean people in the study enjoyed some significant health advantages. The Mediterranean groups have lower mortality rates in all age brackets in form of all causes particularly from heart disease. The study also showed that the Mediterranean diet is as high as or higher in fat than other diets, obtaining up to forty percent of all its calories from fat. It has however, different patterns of fat intake. Mediterranean cooking, in its smaller amounts of saturated fat and higher amount of unsaturated fat, mostly in form of all of oil.

"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 increase interest 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 wa rious 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 connect ion 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
