They know they need to save, but how much? And what exactly are they saving for—to spend more time 36 the grandkids, go traveling, or start another career? It turns out that husbands and wives may have 37 different ideas about, the subject.The deepest divide is in the way spouses envisage their lifestyle in their later years. Fidelity Investments Inc. found 41 percent of the 500 couples it surveyed 38 on whether both or at least one spouse will work in retirement. Wives are generally right regarding their husbands’ retirement age, but men 39 the age their wives will be when they stop working. And husbands are slightly more 40 about their standard of living than wives are.Busy juggling (穷于应付) careers and families, most couples don’t take the time to sit down,41 or together, and think about what they would like to do 5,10 or 20 years from now. They42 they are on the same page, but the 43 is they have avoided even talking about it.If you are self-employed or in a job that doesn’t have a standard retirement age, you may be more apt to delay thinking about these issues. It is often a 44 retirement date that provides the catalyst (催化剂) to start planning. Getting laid off or accepting an early-retirement 45 can force your hand. But don’t wait until you get a severance (遣散费) check to begin planning.注意：此部分试题请在答题卡2上作答。

今天小编为大家整理的是关于2019年6月英语六级作文答案解析，3套齐全哦，希望大家可以好好利用起来，下面就让我们一起来学习一下吧。
试卷一：Motivation and methods in learning The great difference in learning outcomes, especially among those who are almost equally hardworking, has triggered a controversial issue as to the importance of motivation and methods for learning. Views on the topic vary greatly among people from different walks of life. Some believe that motivation and methods are the main factors accounting for the learning effect, but others consider them less important than hardworking. I personally agree with the former for the reasons presented below. Before learning, it is motivation that gets a person started. Without motivation -- that is, without interest or an exam that drives you to learn -- you won't even start the learning process, and naturally there won't be any outcome. During learning, it is again the motivation that encourages the learner not to give up half way. And this is when great methods come along. With proper methods, learning becomes easier and hence less frustrating because a learner can usually achieve more with less learning materials or practice. Consequently, it boosts motivation as well. However, hardworking with improper methods results in failure to produce positive outcome, and aggravates the feeling of frustration. From my perspective, it is crucial that we understand and accept the fact that motivation and methods are more critical to learning than hardworking. Only in this way can we make full use of our efforts and have better learning outcomes. 试卷二：mutual understanding and respect in interpersonal relationships Understanding and respect "You reap what you sow." The wisdom of this saying is not lost in our era, especially when it comes to mutual understanding and respecting others, yet arrogance seems rife nowadays. The implication of this message is, in the case of respect, that if you understand and respect others, you will be understood and respected in return. Understanding and respecting others is rewarding in three aspects. First, from a social standpoint, it enhances mutual trust and reduces the chance of conflicts between people with different beliefs because it urges people to think in others' shoes before criticizing their opinions thereby preventing impulsive conflicts. Moreover, it benefits the understanding and respectful person himself, too. Understanding and respecting others helps him to calm down and take a deeper insight into his own ideas, which means he is more likely to think in the big picture. Finally, we should always bear in mind that respect is earned with respect, and so is understanding, and you will never win them with arrogance and threat. When we understand and respect others, we command them from others as well. There is asimulative effect that kicks in when people stay humble and respect diversity. By respecting and harnessing each other's strengths, we boost opportunity for all people. 试卷三：the importance of team spirit and communication in workplace Team spirit and communication in workplace It is time, at last, to speak the truth about the importance of team spirit and communication, and the truth is this. Team spirit and communication are really not such outdated clichés, especially in the circumstance of the workplace. In the workplace, team spirit and communication are crucial in two aspects. Firstly, a job worth doing is usually worth doing together. Although some people do succeed by working independently, more indications tend to show that teamwork helps people achieve more, and it is the communication that transforms the chaotic crowds into orderly teams. Also, team spirit implies team objectives weigh more than individual accomplishment. It's like an orchestra performance. None of the performers is better than all of them. The performers “communicate” mutely and join their efforts. They know it clearly that no one can whistle a symphony on his own -- it takes a whole orchestra to play it. In a nutshell, team spirit and communication in the workplace shall never be underestimated. Only by working as a team and communicate well with colleagues can one attain greater accomplishment. 相关文章： 1.介绍自己英语作文优秀范文 2.我的宠物英语作文 3.关于介绍自己的英语作文5篇 4.关于周末的英语作文5篇 5.关于我的一天英语作文 6.大学英语作文范文10篇 7.七年级英语作文10篇 8.英语作文。

2019年6月大学英语六级考试真题及参考答案（第1套）Part I Writing (30 minutes)Directions: For this part, you are allowed 30 minutes to write an essay on the importance of motivation and methods in learning.You should write at least 150 words but no more than 200 words.【参考范文】As an old saying goes, knowledge can change one’s life. In order to acquire knowledge, we have to study hard. However, it can not be ignored that effective learning needs both motivation and scientific methods.It’s not difficult for us to come up with several possible reasons accounting for this perspective. In the first place, learning is a kind of serious and hard work. Therefore, not everyone is able to keep going without certain internal motivations. Besides, scientific methods play a significant role in improving learning efficiency. Many of us believe that the longer you study, the better grades you will get. But a lot of experiences of our classmates prove that this view is not entirely correct. In details, studying for a long time is exhausting and it is very likely to decrease study efficiency, which is critical to academic performance.From what has been mentioned above, we can easily draw a conclusion that the importance of motivation and methods in learning is self-evident. And it is necessary for us to develop good learning methods.【参考范文译文】俗话说，知识能改变命运。

C) Having your personal satellite launched into orbit might sound like an idea straight out of science fiction . But over the past few decades a unique class of satellites has been created that fits the bill: CubeSats. The“Cube”here simply refers to the satellite's shape. The most common CubeSat is a 10cm cube, so small that a single CubeSat could easily be mistaken for a paperweight on your desk. These mini-satellites can fit in a launch vehicle's formerly“wasted space.”Multiples can be deployed in combination for more complex missions than could be achieved by one CubeSat alone.

You are required to select one word for each blank from a list of choices given in a wordbank following the passage. Read the passage through carefully beforemaking your choices. Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet 2with a single line through the centre. You may not use any of the wordsin the bank more than once.Questions 26 to 35 are based on the following passage.As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can perk them right up again. During 26 exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a 27 called “central fatigue,” in which an imbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements 28 . It was not known, however, whether central fatigue might also affect motor systems not directly 29 in the exercise itself—such as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydrate 30 eitherwith a moderate dose of caffeine—which is known to stimulate the central nervous system—or as a placebo without, during 3 hours of 31 . After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still 32 their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, 33 their ability to capture new visual information. The caffeine—the equivalent of two strong cups of coffee—was 34 to counteract this effect, with some cyclists even displaying 35 eye movement speeds, the team reports today in Scientific Reports.

Identify the paragraph from which the information isderived. You may choose a paragraph more than once. Each paragraphis marked with a letter. Answer the question by marking thecorresponding letter on Answer Sheet 2.The Blessing and Curse of the People Who Never ForgetA handful of people can recall almost every day of their lives in enormous detail—and after years of research, neuroscientists are finally beginning to understand how they do it.[A] For most of us, memory is a mess of blurred and faded pictures of our lives. Asmuch as we would like to cling on to our past, even the saddest moments can be washed away with time.[B] Ask Nima Veiseh what he was doing for any day in the past 15 years, however,and he will give you the details of the weather, what he was wearing, or even what side of the train he was sitting on his journey to work. “My memory is like a library of video tapes, walk-throughs of every day of my life from walking to sleeping,” he explains.[C] Veiseh can even put a date on when those tapes started recording: 15 December2000, when he met his first girlfriend at his best friend’s 16th birthday party. He had always had a good memory, but the thrill of young love seems to have shifteda gear in his mind: from now on, he would start recording his whole life in detail.“I could tell you everything about every day after that.”[D] Needless to say, people like Veiseh are of great interest to neuroscientists (神经科学专家) hoping to understand the way the brain records our lives. A couple of recent papers have finally opened a window on these people’s extraordinary minds. And such research might even suggest ways for us all to relive our past with greater clarity.[E] ‘Highly superior autobiographical memory’ (or HSAM for short), first come tolight in the early 2000s, with a young woman named Jill Price. Emailing the neuroscientist and memory researcher Jim McGaugh one day, she claimed that she could recall every day of her life since the age of 12. Could he help explain her experiences?[F] McGaugh invited her to his lab, and began to test her: he would give her a dateand ask her to tell him about the world events on that day. True to her word, she was correct almost every time.[G] It didn’t take long for magazines and documentary film-makers to come tounderstand her “total recall”, and thanks to the subsequent media interest, a few dozen other subjects (including Veiseh) have since come forward and contacted the team at the University of California, Irvine.[H] Interestingly, their memories are highly self-centred: although they can remember“autobiographical” life events in extraordinary detail, they seem to be no better than average at recalling impersonal information, such as random (任意选取的) lists of words. Nor are they necessarily better at remembering a round of drinks, say. And although their memories are vast, they are still likely to suffer from “false memories”. Clearly, there is no such thing as a “perfect” memory—their ordinary minds are still using the same flawed tools that the rest of us rely on. The question is, how?[I] Lawrence Patihis at the University of Southern Mississippi recently studied around20 people with HSAM and found that they scored particularly high on twomeasures: fantasy proneness(倾向) and absorption. Fantasy proneness could be considered as a tendency to imagine and daydream, whereas absorption is the tendency to allow your mind to become fully absorbed in an activity—to pay complete attention to the sensations (感受) and the experien ces. “I’m extremely sensitive to sounds, smells and visual detail,” explains Nicole Donohue, who has taken part in many of these studies. “I definitely feel things more strongly than the average person.”[J] The absorption helps them to establish strong foundations for a recollection, says Patihis, and the fantasy proneness means that they revisit those memories again and again in the coming weeks and months. Each time this initial memory trace is “replayed”, it becomes even stronger. In some ways, you pro bably go through that process after a big event like your wedding day—but the difference is that thanks to their other psychological tendencies, the HSAM subjects are doing it day in, day out, for the whole of their lives.[K] Not everyone with a tendency to fantasize will develop HSAM, though, so Patihis suggests that something must have caused them to think so much about their past.“Maybe some experience in their childhood meant that they became obsessed (着迷) with calendars and what happened to them,” says Patihis.[L] The people with HSAM I’ve interviewed would certainly agree that it can be a mixed blessing. On the plus side, it allows you to relive the most transformativeand enriching experiences. Veiseh, for instance, travelled a lot in his youth. In his spare time, he visited the local art galleries, and the paintings are now lodged deep in his autobiographical memories.[M] “Imagine being able to remember every painting, on every wall, in every gall ery space, between nearly 40 countries,” he says. “That’s a big education in art by itself.” With this comprehensive knowledge of the history of art, he has since become a professional painter.[N] Donohue, now a history teacher, agrees that it helped during certain parts of her education: “I can definitely remember what I learned on certain days at school. I could imagine what the teacher was saying or what it looked like in the book.”[O] Not everyone with HSAM has experienced these benefits, however. Viewing the past in high definition can make it very difficult to get over pain and regret. “It can be very hard to forget embarrassing moments,” says Donohue. “You feel the same emotions—it is just as raw, just as fresh… You can’t turn off that stream of m emories, no matter how hard you try.” Veiseh agrees: “It is like having these open wounds—they are just a part of you,” he says.[P] This means they often have to make a special effort to lay the past to rest. Bill, for instance, often gets painful “flashbacks” in which unwanted memories intrude into his consciousness, but overall he has chosen to see it as the best way of avoiding repeating the same mistakes. “Some people are absorbed in the past but not open to new memories, but that’s not the case for m e. I look forward to the each day and experiencing something new.”36. People with HSAM have the same memory as ordinary people when it comes toimpersonal information.37. Fantasy proneness will not necessarily cause people to develop HSAM.38. Veiseh began to remember the details of his everyday experiences after he met hisfirst young love.39. Many more people with HSAM started to contact researchers due to the massmedia.40. People with HSAM often have to make efforts to avoid focusing on the past.41. Most people do not have clear memories of past events.42. HSAM can be both a curse and a blessing.43. A young woman sought explanation from a brain scientist when she noticed herunusual memory.44. Some people with HSAM find it very hard to get rid of unpleasant memories.45. A recent study of people with HSAM reveals that they are liable to fantasy andfull absorption in an activity.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 fourchoices marked A), B), C) and D). You should decide on the best choiceand mark the corresponding letter on Answer Sheet 2 with a single linethrough the centre.Passage 1Questions 46 to 50 are based on the following passage.The phrase almost completes itself: midlife crisis. It’s the stage in the middle of the journey when people feel youth vanishing, their prospects narrowing and death approaching.There’s only one problem with the cliché (套话). It isn’t true.“In fact, there is almost no hard evidence for midlife crisis other than a few small pilot studies conducted decades ago,” Barbara Hagerty writes in her new book, Life Reimagined. The bulk of the research shows that there may be a pause, or a shifting of gears in the 40s or 50s, but this shift “can’t be exciting, rather than terrifying.”Barbara Hagerty looks at some of the features of people who turn midlife into a rebirth. They break routines, because “autopilot is death.” They choose purpose over happiness–having a clear sense of purpose even reduces the risk of Alzenimer’s disease. They give priority to relationships, as careers often recede (逐渐淡化).Life Reimagined paints a picture of middle age that is far from gloomy. Midlife seems like the second big phase of decision-making. Your identity has been formed, you’ve built up your resources; and now you have the chance to take the big risks precisely because your foundation is already secure.Karl Barth described midlife precisely this way. At middle age, he wrote, “the sowing is behind; now is the time to reap. The run has been taken; now is the time toleap. Preparation has been made; now is th e time for the venture of the work itself.”The middle-aged person, Barth continued, can see death in the distance, but moves with a “measured haste” to get big new things done while there is still time.What Barth wrote decades ago is even truer today. People are healthy and energetic longer. We have presidential candidates running for their first term in office at age 68, 69 and 74. A longer lifespan is changing the narrative structure of life itself. What could have been considered the beginning of a descent is now a potential turning point—the turning point you are most equipped to take full advantage of.46. What does the author think of the phrase “midlife crisis”?A) It has led to a lot of debate.B) It is widely acknowledged.C) It is no longer fashionable.D) It misrepresents real life.47. How does Barbara Hagerty view midlife?A) It may be the beginning of a crisis.B) It can be a new phrase of one’s life.C) It can terrifying for the unprepared.D) It may see old-age diseases approaching.48. How is midlife pictured in the book Life Reimagined?A) It can be quite rosy.B) It can be burdensome.C) It undergoes radical transformation.D) It makes for the best part of one’s life.49. According to Karl Barth, midlife is the time .A) to relaxB) to matureC) to harvestD) to reflect50. What does the author say about midlife today?A) It is more meaningful than other stages of life.B) It is likely to change the narrative of one’s life.C) It is more important toe those with a longer lifespan.D) It is likely to be a critical turning point in one’s life.Passage TwoQuestions 51 to 55 are based on the following passage.In spring, chickens start laying again, bringing a welcome source of protein at winter’s end. So it’s no surprise that cultures around the world celebrate spring by honoring the egg.Some traditions are simple, like the red eggs that get baked into Greek Easter breads. Others elevate the egg into a fancy art, like the heavily jewel-covered “eggs” that were favored by the Russians starting in the 19th century.One ancient form of egg art comes to us from Ukraine. For centuries, Ukrainians have been drawing complicated patterns on eggs. Contemporary artists have followed this tradition to create eggs that speak to the anxieties of our age: Life is precious, and delicate. Eggs are, too.“There’s something about their delicate nature that appeals to me,” says New Yorker cartoonist Roz Chast. Several years ago, she became interested in eggs and learned the traditional Ukrainian technique to draw her very modern characters. “I’ve broken eggs at every stage of the process—from the very beginning to the very, very end.”But there’s an appeal in that vulnerability. “There’s part of this sickening horror of knowing you’re walking on the edge with this, that I kind of like, knowing that it could all fall apart at any second.” Chast’s designs, such as worried man alone in a tiny rowboat, reflect that delicateness.Traditional Ukrainian decorated eggs also spoke to those fears. The elaborate patterns were believed to offer protection against evil.“There’s an ancient legend that as long as these eggs are made, evil will not pre vail in the world,” says Joan Brander, a Canadian egg-painter who has been painting eggs for over 60 years, having learned the art from her Ukrainian relatives.The tradition, dating back to 300 B.C., was later incorporated into the Christian church. The old symbols, however, still endure. A decorated egg with a bird on it, given to a young married couple, is a wish for children. A decorated egg thrown into the field would be a wish for a good harvest.51. Why do people in many cultures prize the egg?A) It is a welcome sign of the coming of spring.B) It is their major source of protein in winter.C) It can easily be made into a work of art.D) It can bring wealth and honor to them.52. What do we learn about the decorated “eggs” in Russia?A) They are shaped like jewel cases.B) They are cherished by the rich.C) They are heavily painted in red.D) They are favored as a form of art.53. Why have contemporary artists continued the egg art tradition?A) Eggs serve as an enduring symbol of new life.B) Eggs have an oval shape appealing to artists.C) Eggs reflect the anxieties of people today.D) Eggs provide a unique surface to paint on.54. Why does Chast enjoy the process of decorating eggs?A) She never knows if the egg will break before the design is completed.B) She can add multiple details to the design to communicate her idea.C) She always derives great pleasure from designing something new.D) She is never sure what the final design will look like until the end.55. What do we learn from the passage about egg-painting?A) It originated in the eastern part of Europe.B) It has a history of over two thousand years.C) It is the most time-honored form of fancy art.D) It is especially favored as a church decoration.Part ⅣTranslation (30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Youmay not use any of the words in the bank more than once.Half of your brain stays alert and prepared for danger when you sleep in a new place, a study has revealed. This phenomenon is often 26 to as the “first-night-effect”. Researchers from Brown University found that a network in the left hemisphere of t he brain “remained more active” than the network in the right side of the brain. Playing sounds into the right ears （stimulating the left hemisphere）of 27 was more likely to wake them up than if the noises were played into their left ear.It was 28 observed that the brain was more active during deep sleep. When the researchers repeated the laboratory experiment on the second and third nights they found the left hemisphere could not be stimulated in the same way during deep sleep. The researchers explained that the study demonstrated “when we are i n a 29 environment, the brain partly remains alert so that humans can defend themselves against any 30 danger.”The researchers believe this is the first time that the “first-night-effect” of different brain states has been 31 in humans. It isn’t, however, the first time it has ever been seen. Some animal 32 also display this phenomenon. For example, dolphins, as well as other 33 animals shut down one hemisphere of the brain when they go to sleep. A previous study noted that dolphins always 34 control their breathing. Without keeping the brain active while sleeping, they would probably down. But, as the human study suggest, another reason for dolphins keeping their eyes open during sleep is that they can look out for 35 while asleep. Italso keeps their physiological processes working.Section 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 theinformation is derived. You may choose a paragraph more than once. Each paragraph is markedwith a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The Price of Oil and the Price of Carbon[A]Fossil fuel prices are likely to stay “low for long”. Notwithstanding important recent progre ss in developing renewable fuel sources, low fossil fuel prices could discourage further innovation in, and adoption of, cleaner energy technologies. The result would be higher emissions of carbon dioxide and other greenhouse gases.[B]Policymakers should not allow low energy prices to derail the clean energy transition. Action to restore appropriate price incentives, notably through corrective carbon pricing, is urgently needed to lower the risk of irreversible and potentially devastating effects of climate change. That approach also offers fiscal benefits.[C] Oil prices have dropped by over 60 percent since June 2019. A commonly held view in the oil industry is that “the best cure for low oil prices is low oil prices”. The reasoning behind this saying is that low oil prices discourage investment in new production capacity, eventually shifting the oil supply curve backward and bringing prices back up as existing oil fields—which can be tapped at relatively low marginal cost—are depleted. In fact, in line with past experience, capital expenditure in the oil sector has dropped sharply in many producing countries, including the United States. The dynamic adjustment to low oil prices may, however, be different this time around.[D]Oil prices are expected to remain lower for longer. The advent of new technologies has added about 4.2 million barrels per day to the crude oil market, contributing to a global over-supply. In addition, other factors are putting downward pressure on oil prices: change in the strategic behavior of the Organization of Petroleum Exporting Countries, the projected increase in Iranian exports, the scaling-down of global demand（especially from emerging markets）, the long-term drop in petroleum consumption in the United States, and some displacement of oil by substitutes. These likely persistent forces, like the growth of shale（页岩）, point to a “low for long” scenario. Futures markets, which show only a modest recovery of prices to around $60 a barrel by 2019, support this view.[E]Natural gas and coal—also fossil fuels—have similarly seen price declines that look to be long-lived. Coal and natural gas are mainly used for electricity generation, whereas oil is used mostly to power transportation, yet the prices of all these energy sources are linked. The North American shale gas boom has resulted in record low prices there. The recent discovery of the giant Zohr gas field off the Egyptian coast will eventually have impact on pricing in the Mediterranean region and Europe, and there is significant development potential in many other places, notably Argentina. Coal prices also are low, owing to over-supply and the scaling down of demand, especially from China, which burns half of the world’s coal.[F] Technological innovations have unleashed the power of renewables such as wind, hydro, solar, and geothermal （地热）. Even Africa and the Middle East, home to economies that are heavily dependent on fossil fuel exports, have enormous potential to develop renewables. For example, the United Arab Emirates has endorsed an ambitious target to draw 24% of its primary energy consumption from renewable sources by 2021.[G]Progress in the development of renewables could be fragile, however, if fossil fuel prices remain low for long. Renewables account for only a small share of global primary energy consumption, which is still dominated by fossil fuels—30% each for coal and oil, 25% for natural gas. But renewable energy will have to displace fossil fuels to a much greater extent in the future to avoid unacceptable climate risks.[H]Unfortunately, the current low prices for oil, gas, and coal may provide little incentive for research to find even cheaper substitutes for those fuels. There is strong evidence that both innovation and adoption of cleaner technology are strongly encouraged by higher fossil fuel prices. The same is true for new technologies for alleviating fossil fuel emissions.[I] The current low fossil-fuel price environment will thus certainly delay the energy transition from fossil fuel to clean energy sources. Unless renewables become cheap enough that substantial carbon deposits are left underground for a very long time, if not forever, the planet will likely be exposed to potentially catastrophic climate risks.[J] Some climate impacts may already be discernible. For example, the United Nations Children’s Fund estimates that some 11 million children in Africa face hunger, disease, and water shortages as a result of the strongest ElNiño（厄尔尼诺）weather phenomenon in decades. Many scientists believe that El Niño events, caused by warming in the Pacific, are becoming more intense as a result of climate change.[K]Nations from around the world have gathered in Paris for the United Nations Climate Change Conference, COP 21, with the goal of a universal and potentially legally-binding agreement on reducing greenhouse gas emissions. We need very broad participation to address fully the global tragedy that results when countries fail to take into account the negative impact of their carbon emissions on the rest of the world. Moreover, non-participants by nations, if sufficiently widespread, can undermine the political will of participating countries to act.[L]The nations participating at COP 21 are focusing on quantitative emissions-reduction commitments. Economic reasoning shows that the least expensive way for each country is to put a price on carbon emissions. The reason is that when carbon is priced, those emissions reductions that are least costly to implement will happen first. The International Monetary Fund calculates that countries can generate substantial fiscal revenues by eliminating fossil fuel subsidies and levying carbon charges that capture the domestic damage caused by emissions. A tax on upstream carbon sources is one easy way to put a price on carbon emissions, although some countries may wish to use other methods, such as emissions trading schemes. In order to maximize global welfare, every country’s carbon pricing should reflect not only th e purely domestic damages from emissions, but also the damages to foreign countries.[M]Setting the right carbon price will therefore efficiently align the costs paid by carbon users with the true social opportunity cost of using carbon. By raising relative demand for clean energy sources, a carbon price would also help to align the market return to clean-energy innovation with its social return, spurring the refinement of existing technologies and the development of new ones. And it would raise the demand for technologies such as carbon capture and storage, spurring their further development. If not corrected by the appropriate carbon price, low fossil fuel prices are not accurately signaling to markets the true social profitability of clean energy. While alternative estimates of the damages from carbon emissions differ, and it’s especially hard to reckon the likely costs of possible catastrophic climate events, most estimates suggest substantial negative effects.[N] Direct subsidies to research and development have been adopted by some governments but are a poor substitute for a carbon price: they do only part of the job, leaving in place market incentives to over-use fossil fuels and thereby add to the stock of atmospheric greenhouse gases without regard to the collateral（附带的）costs.[O] The hope is that the success of COP 21 opens the door to future international agreement on carbon prices. Agreement on an international carbon-price floor would be a good starting point in that process. Failure to address comprehensively the problem of greenhouse gas emissions, however, exposes all generations, present and future, to incalculable risks.36. A number of factors are driving down the global oil prices not just for now but in the foreseeable future.37. Pricing carbon proves the most economical way to reduce greenhouse gas emissions.38. It is estimated that extreme weather conditions have endangered the lives of millions of African children.39. The prices of coal are low as a result of over-supply and decreasing demand.40. Higher fossil fuel prices prove to be conducive to innovation and application of cleaner technology.41. If fossil fuel prices remain low for a long time, it may lead to higher emissions of greenhouse gases.42. Fossil fuels remain the major source of primary energy consumption in today’s world.43. Even major fossil exporting countries have great potential to develop renewable energies.44. Greenhouse gas emissions, if not properly dealt with, will pose endless risks for mankind.45. It is urgent for governments to increase the cost of using fossil fuels to an appropriate level to lessen thecatastrophic effects of climate change.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide onthe best choice and mark the corresponding letter on Answer Sheet 2 with a single line through thecentre.Passage OneQuestions 46 to 50 are based on the following passage.Tennessee’s technical and community college will not outsource（外包）management of their facilities to a private company, a decision one leader said was bolstered by an analysis of spending at each campus.In an email sent Monday to college presidents in the Tennessee Board of Regents system, outgoing Chancellor John Morgan said an internal analysis showed that each campus’ spending on facilities management fell well below the industry standards identified by the state. Morgan said those findings—which included data from the system’s 13 community colleges, 27 technical colleges and six universities—were part of the decision not to move forward with Governor Bill Haslam’s proposal to privatize management of state buildings in an effort to save money.“While these numbers are still being validated by the state, we feel any adjustments they might suggest will be immaterial,” Morgan wrote to the presidents. “System institutions are operating very efficiently based on this analysis, raising the question of the value of pursing a broad scale outsourcing initiative.”Workers’ advocates have criticized Haslam’s plan, saying it would mean some campus workers would lose their jobs or benefits. Haslam has said colleges would be free to opt in or out of the outsourcing plan, which has not been finalized.Morgan notified that Haslam administration of his decision to opt out in a letter sent last week. That letter, which includes several concerns Morgan has with the plan, was originally obtained by The Commercial Appeal in Memphis.In an email statement from the state’s Office of Customer Focused Government, which is examining the possibility of outsourcing, spokeswoman Michelle R. Martin said officials were still working to analyze the datafrom the Board of Regents. Data on management expenses at the college system and in other state departments will be part of a “business justification” the state will use as officials deliberate the specifics of an outsourcing plan.“The state’s facilities management project team is still in the process of developing its bu siness justification and expects to have that completed and available to the public at the end of February,” Martin said. “At this time there is nothing to take action on since the analysis has yet to be completed.”Morgan’s comments on outsourcing mark th e second time this month that he has come out against one of Haslam’s plans for higher education in Tennessee. Morgan said last week that he would retire at the end of January because of the governor’s proposal to split off six universities of the Board of Regents system and create separate governing boards for each of them. In his resignation letter, Morgan called the reorganization “unworkable”.46. What do we learn about the decision of technical and community colleges in Tennessee?A）It is backed by a campus spending analysis.B）It has been flatly rejected by the governor.C）It has neglected their faculty’s demands.D）It will improve their financial situation.47. What does the campus spending analysis reveal?A）Private companies play a big role in campus management.B）Facilities management by colleges is more cost-effective.C）Facilities management has greatly improved in recent years.D）College exercise full control over their own financial affairs.48. Workers’ supporters argue that Bill Haslam’s prop osal would ______.A）deprive colleges of the right to manage their facilitiesB）make workers less motivated in performing dutiesC）render a number of campus workers joblessD）lead to the privatization of campus facilities49. What do we learn from the stat e spokeswoman’s response to John Morgan’s decision?A）The outsourcing plan is not yet finalized.B）The outsourcing plan will be implemented.C）The state officials are confident about the outsourcing plan.D）The college spending analysis justifies the outsourcing plan.50. Why did John Morgan decide to resign?A）He had lost confidence in the Tennessee state government.B）He disagreed with the governor on higher education policies.C）He thought the state’s outsourcing proposal was simply unworkable.D）He opposed the governor’s plan to reconstruct the college board system.Passage TwoQuestions 51 to 55 are based on the following passage.Macy’s reported its sales plunged 5.2% in November and December at stores open more than a year, a disappointing holiday season performance that capped a difficult year for a department store chain facing wide-ranging challenges. Its flagship stores in major U.S. cities depend heavily on international tourist spending, which shrank at many retailers due to a strong dol lar. Meanwhile, Macy’s has simply struggled to lure consumers who are more interested in spending on travel or dining out than on new clothes or accessories.The company blamed much of the poor performance in November and December on unseasonably warm weat her. “About 80% of our company’s year-over-year declines in comparable sales can be attributed to shortfalls（短缺）in cold-weather goods,” said chief executive Terry Lundgren in a press release. This prompted the company to cut its forecasts for the full fourth quarter.However, it’s clear that Macy’s believes its troubles run deeper than a temporary aberration（偏离）off the thermometer. The retail giant said the poor financial performance this year has pushed it to begin implementing $400 million in cost-cutting measures. The company pledged to cut 600 back-office positions, though some 150 workers in those roles would be reassigned to other jobs. It also plans to offer “voluntary separation” packages to 165 senior executives. It will splash staffing at its fleet of 770 stores, a move affecting some 3,000 employees.The retailer also announced the locations of 36 stores it will close in early 2019. The company had previously announced the planned closures, but had not said which locations would be affected. None of the chain’s stores in the Washington metropolitan area are to be closed.Macy’s has been moving aggressively to try to remake itself for a new era of shopping. It has plans to open more locations of Macy’s Backstage, a newly-developed off-price concept which might help it better compete with ambitious T.J. Maxx. It’s also pushing ahead in 2019 with an expansion of Bluemercury, the beauty chain it bought last year. At a time when young beauty shoppers are often turning to Sephora or Ulta instead of department store beauty counters, Macy’s hopes Bluemercury will help strengthen its position in th e category.One relative bright spot for Macy’s during the holiday season was the online channel, where it rang up “double-digit” increases in sales and a 25% increase in the number of orders it filled. That relative strength would be consistent with what was seen in the wider retail industry during the early part of the holiday season. While Thanksgiving, Black Friday and Cyber Monday all saw record spending online, in-store sales plunged over the holiday weekend.51. What does the author say about the shrinking spending of international tourists in the U.S.?A）It is attributable to the rising value of the U.S. dollar.B）It is a direct result of the global economic recession.C）It reflects a shift of their interest in consumer goods.D）It poses a potential threat to the retail business in the U.S.52. What does Macy’s believe about its problems?A）They can be solved with better management.B）They cannot be attributed to weather only.C）They are not as serious in its online stores.D）They call for increased investments.53. In order to cut costs, Macy’s decided to _______.A）cut the salary of senior executivesB）relocate some of its chain storesC）adjust its promotion strategiesD）reduce the size of its staff54. Why does Macy’s plan to expand Bluemercury in 2019?A）To experiment on its new business concept.B）To focus more on beauty products than clothing.C）To promote sales of its products by lowering prices.D）To be more competitive in sales of beauty products.55. What can we learn about Macy’s during the holiday season?A）Sales dropped sharply in its physical stores.B）Its retail sales exceeded those of T.J. Maxx.C）It helped Bluemercury establish its position worldwide.D）It filled its stores with abundant supply of merchandise.Part VI Translation （30 minutes）Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2with a single line through the 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.The number of devices you can talk to is multiplying—first it was your phone, then your car, and now you can tell your kitchen appliances what to do. But even without gadgets that understand our spoken commands, research suggests that, as bizarre as it sounds, under certain 26 , people regularly ascribe human traits to everyday objects.Sometimes we see things as human because we are 27 . In one experiment, people who reported feeling isolated were more likely than others to attribute 28 to various gadgets. In turn, feeling close to objects can 29 loneliness. When college students were reminded of a time they had been 30 in a social setting, they compensated by exaggerating their number of friends—unless they were first given tasks that caused them to interact with their phone as if it had human qualities. According to the researchers, the participants' phones 31 substituted for real friends.At other times, we personify products in an effort to understand them. One study found that three in four respondents yelled at their computer. Further, the more their computer gave them problems, the more likely the respondents were to report that it had its own “beliefs and 32 .”So how do people assign traits to an object? In part, we rely on looks. On humans, wide faces are 33 with dominance. Similarly, people rated cars, clocks, and watches with wide faces as more dominant-looking than narrow-faced ones, and preferredthem—especially in 34 situations. An analysis of car sales in Germany found that cars with gills (护栅) that were upturned like smiles sold best. The purchasers saw this 35 as increasing a car's friendliness.A) alleviate I) desiresB) apparently J) excludedC) arrogant K) featureD) associated L) lonelyE) circumstances M) separateF) competitive N) spectacularlyG) conceded O) warrantH) consciousnessSection 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.[A] Though he didn’t come from a farming family, from a young age Tim Joseph was fascinated by the idea of living off the land. Reading magazines like The Stockman Grass Farmer and Graze, he got hooked on the idea of grass-fed agriculture. The idea that all energy and wealth comes from the sun really intrigued him He thought the shorter the distance between the sun and the end product, the higher the profit to the farmer.[B] Joseph wanted to put this theory to the test. In 2009, he and his wife Laura launched Maple Hill Creamery, an organic, all grass-fed yogurt company in northern New York. He quickly learned what the market has demonstrated: Demand forgrass-fed products currently exceeds supply. Grass-fed beef is enjoying a 25-30% annual growth rate. Sales of grass-fed yogurt and kefir (发酵乳饮品) on the other hand, have in the last year increased by over 38%. This is in comparison with a drop of just under 1% in the total yogurt and kefir market according to natural and organic marketresearch company SPINS. Joseph’s top priority became getting his hands on enough grass-fed milk to keep customers satisfied, since his own 64-cow herd wasn’t going to suffice[C] His first partnership was with Paul and Phyllis Amburgh, owners of the Dharma Lea farm in New York. The Amburghs, too, were true believers in grass-fed. In addition to supplying milk from their own 85-head herd, they began to help other farmers in the area convent from conventional to certified organic and grass-fed in order to enter the Maple Hill supply chain. Since 2010, the couple has helped 125 small dairy farms convert to grass-fed, with more than 80% of those farms coming on board during the last two years.[D] All this conversion has helped Maple Hill grow 40-50% every year since it began with no end in sight. Joseph has learned that a farmer has to have a certain mindset to successfully convert. But convincing open-minded dairy people is actually not that hard, when you look at the economics. Grass-fed milk can fetch up to 2.5 times the price of conventional milk. Another factor is the squeeze that conventional dairy farmers have felt as the price of grain they feed their cows has gone up, tightening their profit margins. By replacing expensive grain feed with regenerative management practices, grass-fed farmers are insulated from jumps in the price of feed. These practices include grazing animals on grasses grown from the pastureland’s natural seed bunk, and fertil ized by the cows’ own fertilizer[E] Champions of this type of regenerative grazing also point to its animal welfare, climate and health benefits: Grass-fed animals live longer out of confinement. Grazing herds stimulate microbial (微生物的) activity in the soil, helping to capture water and separate carbon. And grass-fed dairy and meat have been shown to be higher in certain nutrients and healthy fats.[F] In the grass fed system, farmers are also not subject to the wildly fluctuating milk prices of the international commodity market. The unpredictability of global demand and the lag-time it takes to add more cows to a herd to meet demand can result in events like the recent cheese surplus. Going grass-fed is a safe refuge, a way for family-scale farms to stay viable. Usually a farmer will get to the point where financially, what they’re doing is not working. That’s when they call Maple Hill. If the farm is well managed and has enough land, and the desire to convert is sincere, a relationship can begin. Through regular regional educational meetings, a large annual meeting, individual farm visits and thousands of phone calls, the Amburghs pass on the principles of pasture management. Maple Hill signs a contract pledging to buy the farmer’s milk at a guaranteed bas e price, plus quality premiums and incentives for higher protein, butter fat and other solids.[G] While Maple Hill's conversion program is unusually hands on and comprehensive, it’s just one of a growing number of businesses committed to slowly changing t he way America farms. Joseph calls sharing his knowledge network through peer-to-peer learning a core piece of the company’s culture. Last summer, Massachusetts grass-fed beef advocate John Smith launched Big Picture Beef, a network of small grass-fed beef farms in New England and New York that is projected to bring to market 2,500 head of cattle from 125 producers this year. Early indications are that Smith will have no shortage of farm members. Since he began to informally announce the network at farming conferences and on social media, he’s received a steady stream of inquiries from interested farmers.[H] Smith says he’ll provide services ranging from formal seminars to on-farm workshops on holistic (整体的) management, to one-on-one hand-holding and an almost 24/7 phone hotline for farmers who are converting. In exchange, he guarantees an above-market price for each animal and a calf-to-customer electronic ear tag ID system like that used in the European Union.[1] Though advocates portray grass fed products as a win-win situation for all, they do have downsides. Price, for one, is an issue. Joseph says his products are priced10-20% above organic versions, but depending on the product chosen, compared to non-organic conventional yogurt, consumers could pay a premium of 30-50% or more for grass-fed. As for the meat, Smith says his grass-fed hamburger will be priced20-25% over the conventional alternative. But a look at the prices on online grocer Fresh Direct suggests a grass-fed premium of anywhere from 35-60%，[J] And not every farmer has the option of going grass-fed. For both beef and dairy production it requires, at least in the beginning, more pastureland. Grass-fed beef production tends to be more labor-intensive as well. But Smith counters that if you factor in the hidden cost of government corn subsidies, environment degradation, and decreased human heath and animal welfare, grass-fed is the more cost-effective model. “The sun provides the lowest cost of production and the cheapest meat,” he says.[K] Another grass-fed booster spurring farmers to convert is EPIC, which makes meat-based protein bars. Founders Taylor Collins and his wife, Katie Forrest, used to be endurance athletes; now they’re advocates of grass-fed meat. Soon after launching EPIC’S mo st successful product - the Bison Bacon Cranberry Bar - Collins and Forrest found they’d exhausted their sources for bison (北美野牛) raised exclusively on pasture. When they started researching the supply chain, they learned that only 2-3% of all bison is actually grass-fed. The rest is feed-lot confined and fed grain and corn. [L] But after General Mills bought EPIC in 2016, Collins and Forrest suddenly had the resources they needed to expand their supply chain. So the company teamed up withWisconsin-based rancher Northstar Bison. EPIC fronted the money for the purchase of $2.5 million worth of young bison that will be raised according to its grass-fed protocols, with a guaranteed purchase price. The message to young people who might not otherwise be able to afford to break into the business is,“You can purchase this $3 million piece of land here, because I’m guaranteeing you today you'll have 1,000 bison on it.’ We’re bringing new blood into the old, conventional farming ecosystem, which is really cool to see,” Collins explains.36. Farmers going grass-fed are not affected by the ever-changing milk prices of the global market.37. Over the years, Tim Joseph’s partners have helped many dairy farmers to switch to grass-fed.38. One advocate believes that many other benefits should be taken into consideration when we assess the cost-effectiveness of grass-fed farming.39. Many dairy farmers were persuaded to switch to grass-fed when they saw its advantage in terms of profits.40. Tim Joseph’s grass-fed program is only one example of how American farming practice is changing.41. Tim Joseph was fascinated by the notion that sunlight brings energy and wealth to mankind.42. One problem with grass-fed products is that they are usually more expensive than conventional ones.43. Grass fed products have proved to be healthier and more nutritious.44. When Tim Joseph started his business, he found grass-fed products fell short of demand.45. A snack bar producer discovered that the supply of purely grass-fed bison met was scarce.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 markedA）, B）, C）and D）. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Schools are not just a microcosm(缩影) of society: they mediate it too. The best seek to alleviate the external pressures on their pupils while equipping them better to understand and handle the world outside-- at once sheltering them and broadening their horizons. This is ambitious in any circumstances. and in a divided and unequal society the two ideals can clash outright(直接地).Trips that many adults would consider the adventure of a lifetime-treks in Borneo, a sports tour to Barbados-appear to have become almost routine at some state schools. Parents are being asked for thousands of pounds. Though schools cannot profit from these trips, the companies that arrange them do. Meanwhile, pupils arrive at school hungry because their families can’t afford breakfast. The Child Poverty Action Group says nine out of 30 in every classroom fall below the poverty line. The discrepancy is startlingly apparent. Introducing a fundraising requirement for students does not help, as better-off children can tap up richer aunts and neighbours.Probing the rock pools of a local beach or practising French on a language exchange can fire c hildren’s passions, boost their skills and open their eyes to life’s possibilities. Educational outings help bright but disadvantaged students to get better scores inA-level tests. In this globalised age, there is a good case for international travel. and some parents say they can manage the cost of a school trip abroad more easily than a family holiday. Even in the face of immense and mounting financial pressures. some schools have shown remarkable determination and ingenuity in ensuring that all their pupils are able to take up opportunities that may be truly life-changing. They should be applauded. Methods such as whole-school fundraising. with the proceeds(收益) pooled, can help to extend opportunities and fuel community spirit.But ￡3,000 trips cannot be justified when the average income for families with children is just over ￡30,000. Such initiatives close doors for many pupils. Some parents pull their children out of school because of expensive field trips. Even parents who can see that a trip is little more than a party or celebration may well feel guilt that their child is left behind.The Department for Education’s guidance says schools can charge only for board and lodging if the trip is part of the syllabus, and that students receiving government aid are exempt from these costs. However, many schools seem to ignore the advice; and it does not cover the kind of glamorous, exotic trips. which are becoming increasinglycommon. Schools cannot be expected to bring together communities single-handed. But the least we should expect is that they do not foster divisions and exclude those who are already disadvantaged.46. What does the author say best schools should do?A) Prepare students to both challenge and change the divided unequal society.B) Protect students from social pressures and enable them to face the world.C) Motivate students to develop their physical as well as intellectual abilities.D) Encourage students to be ambitious and help them to achieve their goals.47. What does the author think about school field trips?A) They enable students from different backgrounds to mix with each other.B)They widen the gap between privileged and disadvantaged students.C) They give the disadvantaged students a chance to see the world.D) They only benefit students with rich relatives and neighbours.48. What does the author suggest can help build community spirit?A) Events aiming to improve community services.B) Activities that help to fuel students’ ingenuity.C) Events that require mutual understanding.D) Activities involving all students on campus.49. What do we learn about low-income parents regarding school field trips?A) They want their children to participate even though they don’t see much benefit.B) They don’t want their kids to participate but find it hard to keep them from going.C) They don’t want their kids to miss any chance to broaden their horizons despite the cost.D)They want their children to experience adventures but they don’t want them to run risks,50. What is the author’s expectat ion of schools?A) Bringing a community together with ingenuity.B) Resolving the existing discrepancies in society.C) Avoiding creating new gaps among students.D) Giving poor students preferential treatment.Passage TwoQuestions 51 to 55 are based on the following passage.Rising temperatures and overfishing in the pristine(未受污染的) waters around the Antarctic could see king penguin populations pushed to the brink of extinction by the end of the century, according to a new study. The study’s report states that as global warming transforms the environment in the world’s last great wilderness, 70 percent of king penguins could either disappear or be forced to find new breeding grounds.Co-author Céline Le Bohec, from the University of Strasbourg in France, w arned:“If there’re no actions aimed at haling or controlling global warming, and the pace of the current human- induced changes such as climate change and overfishing stays the same, the species may son disappear.” The findings come amid growing concern ov er the future of the Antarctic. Earlier this month a separate study found that a combination of climate change and industrial fishing is threatening the krill (磷虾) population in Antarctic waters, with a potentially disastrous impact on whales, seals and penguins. But today’s report is the starkest warning yet of the potentially devastating impact of climate change and human exploitation on the Antarctic’s delicate ecosystems.Le Bohec said: “Unless current greenhouse gas emissions drop, 70 percent of king penguins - 1.1 million breeding pairs - will be forced to relocate their breeding grounds, or face extinction by 2100.” King penguins are the second-largest type of penguin and only breed on specific isolated islands in the Southern Ocean where there is no ice cover and easy access to the sea. As the ocean warms, a body of water called the Antarctic Polar Front - an upward movement of nutrient-rich sea that supports a hugeabundance of marine life - is being pushed further south, This means that king penguins, which feed on fish and krill in this body of water, have to travel further to their feeding grounds, leaving their hungry chicks for longer. And as the distance between their breeding grounds and their food grows, entire colonies could be wiped out.Le Bohec said:“The plight of the king penguin should serve as a warning about the future of the entire marine environment in the Antarctic. Penguins, like other seabirds and marine mammals, occupy higher levels in the food chain and they are what we call bio-indicators of their ecosystems." Penguins are sensitive indicators of changes in marine ecosystems. As such, they are key species for understanding and predicting impacts of global change on Antarctic and sub-Antarctic marine ecosystems. The report found that although some king penguins may be able to relocate to new breeding grounds closer to their retreating food source, suitable new habitats would be scarce. Only a handful of islands in the Southern Ocean are suitable for sustaining large breeding colonies.51. What will happen by 2100, according to a new study?A)King penguins in the Antarctic will be on the verge of dying out.B)Sea water will rise to a much higher level around the Antarctic.C) The melting ice cover will destroy the great Antarctic wilderness.D) The pristine waters around the Antarctic will disappear forever.52. What do we learn from the findings of a separate study?A)Shrinking krill population and rising temperatures could force Antarctic whales to migrate.B)Human activities have accelerated climate change in the Antarctic region in recent years.C)Industrial fishing and climate change could be fatal to certain Antarctic species.D)Krill fishing in the Antarctic has worsened the pollution of the pristine waters.53. What does the passage say about king penguins?A) They will turn out to be the second-largest species of birds to become extinct.B) Many of them will have to migrate to isolated islands in the Southern Ocean.C) They feed primarily on only a few kinds of krill in the Antarctic Polar Front.D) The majority of them may have to find new breeding grounds in the future.54. What happens when sea levels rise in the Antarctic?A) Many baby king penguins can’t have food in time.B) Many king penguins could no longer live on krill.C) Whales will invade king penguins’ breeding grounds.D) Whales will have to travel long distances to find food.55. What do we learn about the Southern Ocean?A)The king penguins there are reluctant to leave for new breeding grounds.B)Its conservation is key to the sustainable propagation of Antarctic species.C)It is most likely to become the ultimate retreat for species like the king penguin.D)Only a few of its islands can serve as huge breeding grounds for king penguins.Part Ⅳ Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

In order to acquire knowledge, we have to study hard. However, it can not be ignoredthat effective learning needs both motivation and scientific methods.It ’s not difficult for us to come up with several possible reasonsaccounting for this perspective. In the first place, learning is a kindof serious and hard work. Therefore, not everyone is able to keep goingwithout certain internal motivations. Besides, scientific methods playa significant role in improving learning efficiency. Many of us believethat the longer you study, the better grades you will get. But a lot ofexperiences of our classmates prove that this view is not entirely correct. In details, studying for a long time is exhausting and it is very likelyto decrease study efficiency,which is critical to academic performance.From what has been mentioned above, we can easily draw a conclusion that the importance of motivation and methods in learning is self-evident. And it is necessary for us to develop good learning methods.【参考范文译文】俗话说，知识能改变命运。

This universal consistency among education experts indisputably demonstrates an immutable principle of learning: initiative and correct methods are fundamental to academic success.Highly motivated students find learning pleasant and rewarding, and therefore maintain a strong desire to acquire new knowledge and skills, and enough courage to meet new challenges. Unmotivated students, in contrast, feel like they are forced to learn and get bored easily with this seemingly endless process. In addition, proper methods are a contributing factor in increased efficiency and positive learning outcomes. Top students don't necessarily spend the most amount of t ime on learning, but more often than not have found the right ways to improve their academic performance.It is widely acknowledged that there aren't any shortcuts to learning. But at least, a high level of m otivation and smart strategies make someone a dedicated and efficient learner.【范文译文】任何有经验的老师都会设法激发学生的学习积极性，引导学生寻找适合自己的学习方法。

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than onceSteel is valued for its reliability, but not when it gets cold. Most forms of steel 26 become brittle (脆的）at temperatures below about -25 unless they are mixed with other metals. Now, though, a novel type of steel has been developed that resists 27 at much lower temperatures, while retaining its strength and toughness —without the need for expensive 28.Steel's fragility at low temperatures first became a major concern during the Second World War. After German U-boats torpedoed ( 用鱼雷攻击）numerous British ships, a 2,700-strong fleet of cheap-and-cheerful"Liberty ships"was introduced to replace the lost vessels, providing a lifeline for the 29 British. But the steel shells of hundreds of the ships 30 in the icy north Atlantic, and 12 broke in half and sankBrittleness remains a problem when building steel structures in cold conditions, such as oil rigs in the Arctic So scientists have 31 to find a solution by mixing it with expensive metals such as nickel.Yuuji Kimura and colleagues in Japan tried a more physical 32 . Rather than adding other metals, they developed a complex mechanical process involving repeated heating and very severe mechanical deformation, known as tempforming.The resulting steel appears to achieve a combination of strength and toughness that is 33 to that of modem steels that are very rich in alloy content and, therefore, very expensive.Kimura's team ends to use its tempfomed steel to make ultra-high strength parts, such as bolts. They hope to reduce both the number of 34 needed in a construction job and their weight—by repl aci ng solid supports with 35 tubes, for example. This could reduce the amount of steel needed to make everything from automobiles to buildings and bridgesSection 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 2The future of personal satellite technology is here_are we ready for it?A)Satellites used to be the exclusive playthings of rich governments and wealthy corporations. But increasingly, as space becomes more democratized, they are coming within reach ordinary people. Just like drones (无人机） before them, miniature satellites are beginning to fundamentally transform our conceptions of who gets to do what up above our headsB)A s a recent report from the National Academy of Sciences highlights, these satellites holdtremendous potential for making satellite-based science more accessible than ever before. However,as the cost of getting your own satellite in orbit drops sharply, the risks of irresponsible use grow. The question here is no longer"Can we?"but"Should we?"What are the potential downsides of having a slice of space densely populated by equipment built by people not traditionally labeled as"professionals"? And what would the responsible and beneficial development and use of this technology actually look like? Some of the answers may come from a nonprofit organization that has been building and launching amateur satellites for nearly 50 yearsC)H aving your personal satellite launched into orbit might sound like an idea straight out of science fiction. But over the past few decades a unique class of satellites has been created that fits the bill: CubeSats The"Cube"here simply refers to the satellite's shape. The most common CubeSat is a I0cm cube, so small that a single CubeSat could easily be mistaken for a paperweight on your desk. These mini-satellites can fit m a launch vehicle's formerly"wasted space."Multiples can be deployed in combination for more complex m1ss10ns than could be achieved by one CubeSat aloneD)D) Within their compact bodies these minute satellites are able to house sensors and communications receivers/transmitters that enable operators to study Earth from space, as well as space around Earth. They're primarily designed for Low Earth Orbit (LEO) - an easily accessible region of space from around 200 to 800 miles above Earth, where human-tended missions like the Hubble Space Telescope and the International Space Station (ISS) hang out. But they can attain more distant orbits; NASA plans for most of its future Earth-escaping payloads (to the moon and Mars especially) to carry CubeSats.E)D) Within their compact bodies these minute satellites are able to house sensors and communications receivers/transmitters that enable operators to study Earth from space, as well as space around Earth.

But they can attain more distant orbits; NASA plans for most of its future Earth-escaping payloads (to the moon and Mars especially) to carry CubeSats.F)The first CubeSat was created in the early 2000s, as a way of enabling Stanford graduate students to design, build, test and operate a spacecraft with similar capabilities to the USSR's Sputnik (前苏联的人造卫星）. Since then, NASA, the National Reconnaissance Office and even Boeing have all launched and operated CubeSats There arc more than 130 currently in operation. The NASA Educational Launch of Nano Satellite program, which offers free launches for educational groups and science missions, is now open to U.S. nonprofit corporations as well. Clearly, satellites are not just for rocket scientists anymoreG)The National Academy of Sciences report emphasizes CubeSats' importance in scientific discovery and the training of future space scientists and engineers. Yet it also acknowledges that widespread deployment of LEO CubeSats isn't risk-flee. The greatest concern the authors raise is space debris - pieces of“junk”that orbit the earth, with the potential to cause serious damage if they collide with operational units, including the ISSH)The National Academy of Sciences report emphasizes CubeSats' importance in scientific discovery and the training of future space scientists and engineers.

The greatest concern the authors raise is space debris - pieces of“junk”that orbit the earth, with the potential to cause serious damage if they collide with operational units, including J)In 1969, the Radio Amateur Satellite Corporation (AMSAT) was created in order to foster ham radio enthusiasts' (业余无线电爱好者) participation in space research and communication. It continued the efforts, begun in 1961, by Project OSCAR- a U.S.-based group that built and launched the very first nongovernmental satellite just four years after Sputnik. As an organization of volunteers, AMSAT was putting“amateur”satellites in orbit decades before the current CubeSat craze. And over time, its members have learned a thing or two about responsibility.K)H ere, open.source development has been a central principle, Within the organization, AMSAT has a philosophy of open sourcing everything making technical data on all aspects of their satellites fully available to everyone in the organization, and when possible, the public. According to a member of the team responsible for FOX 1-A, AMSAT's first CubeSat, this means that there s no way to sneak something like explosives or an energy emitter into an amateur satellite when everyone has access to the designs and implementation.However, they're more cautious about sharing information with nonmembers, as the organization guards against others developing the ability to hijack and take control of their satellites. This form of“self-governance”is possible within long-standing amateur organizations that, over time, are able to build a sense of responsibility to community members, as well as society in general. But what happens when new players emerge, who don't have deep roots within the existing culture?L)Hobbyists and students are gaining access to technologies without being part of a long-standing amateur establishment. They're still constrained by funders, launch providers and a series of regulations - all of which rein in what CubeSat developers can and cannot do. But there's a danger they're ill-equipped to think through potential unintended consequences. What these unintended consequences might be is admittedly far from clear. Yet we know innovators can be remarkably creative with taking technologies in unexpected directions. Think of something as seemingly benign as the cellphone - we have microfinance and text-based social networking at one end of the spectrum, and improvised (临时制作的) explosive devices at the other.M)This is where a culture of social responsibility around CubeSats becomes important - not simply to ensure that physical risks are minimized, but to engage with a much larger community in anticipating and managing less obvious consequences of the technology. This is not an easy task. Yet the'evidence from AMSAT and other areas of technology development suggests that responsible amateur communities can and do emerge around novel technologies. The challenge here, of course, is ensuring that what an amateur communities considers to be responsible, actually is. Here's where there needs to be a much wider public conversation that extends beyond government agencies and scientific communities to include students, hobbyists, and anyone who may potentially stand to be affected by the use of CubeSat technology.36.Given the easier accessibility to space, it is time to think about how to prevent misuse ofsatellites.37.A group of mini-satellites can work together to accomplish more complex tasks .38.The greater accessibility of mini-satellites increases the risks oftheir irresponsible use39.Even school pupils can have their CubeSats put in orbit owing to the lowered launching cost.40.AMSAT is careful about sharing information with outsiders to prevent hijacking oftheir satellites.41.NASA offers to launch CubeSats free of charge for educational and research purposes.42.Even with constraint, it is possible for some creative developers to take the CubeSat technology in directions that result in harmful outcomes43.While making significant contributions to space science, CubeSats may pose hazards to other space vehicles .44.Mini-satellites enable operators to study Earth from LEO and space around it.45.AMSAT operates on the principle of h aving all its technical data accessible to its members,preventing the abuse ofamateur satellites.Section CDirections: There are 2 passages in this section.Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C)and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centrePassage OneQuestions 46 to 50 are based on the following passage.When I re-entered the full-time workforce a few years ago after a decade of solitary self-employment, there was one thing I was looking forward to the most: the opportunity to have work friends once again. It wasn’t until I entered the corporate world that I realized, for me at least, being friends with colleagues didn’t emerge as a priority at all. This is surprising when you consider the prevailing emphasis by scholars and trainers and managers on the importance of cultivating close interpersonal relationships at work. So much research has explored the way in which collegial (同事的) ties can help overcome a range of workplace issues affecting productivity and the quality of work output such as team-based conflict, jealousy, undermining, anger, and more.Perhaps my expectations of lunches, water-cooler gossip and caring, deep-and-meaningful conversations were a legacy of the last time I was in that kind of office environment. Whereas now, as I near the end of my fourth decade, I realize work can be fully functional and entirely fulfilling without needing to be best mates with the people sitting next to you.In an academic analysis just published in the profoundly-respected Journal of Management, researchers have looked at the concept of “indifferent relationships”.It’s a simple term that encapsulates (概括) the fact that relationships at work can reasonably be non-intimate, inconsequential, unimportant and even, dare I say it, disposable or substitutable.Indifferent relationships are neither positive nor negative. The limited research conducted thus far indicates they’re especially dominant among those who value independence over cooperation, and harmony over confrontation. Indifference is also the preferred option among those who are socially lazy. Maintaining relationships over the long term takes effort. For some of us, too much effort.As noted above, indifferent relationships may not always be the most helpful approach in resolving some of the issues that pop up at work. But there are nonetheless several empirically proven benefits. One of those is efficiency. Less time chatting and socializing means more time working and churning (产出）.The other is self-esteem. As human beings, we're primed to compare ourselves to each other in what 1s an anxiety-inducing phenomenon. Apparently, we look down on acquaintances more so than friends. Since the former is most common among those inclined towards indifferent relationships, their predominance can bolster individuals' sense of self-worth.Ego aside, a third advantage is that the emotional neutrality of indifferent relationships has been found to enhance critical evaluation, to strengthen one's focus on task resolution, and to gain greater access to valuable information. None ofthat might be as fun as after-work socializing but, hey, I'll take it anyway46.What did the author realize when he re-entered the corporate world?A)Making new friends with his workmates was not as easy as he had anticipatedB)Cultivating positive interpersonal relationships helped him expel solitary feelings.C)Working in the corporate world requires more interpersonal skills than self-employment.D)Building close relationships with his colleagues was not as important as he had expected47.What do we learn from many studies about collegial relationships?A)Inharmonious relationships have an adverse effect on productivityB)Harmonious relationships are what many companies s aim to cultivateC)Close collegial relationships contribute very little to product qualityD)Conflicting relationships in the workplace exist almost everywhere48.What can be inferred about relationships at work from an academic analysis?A)They should be cultivatedB)They are virtually irrelevantC)They are vital to corporate cultureD)They should be reasonably intimate49.What does the author say about people who are socially lazy?A)They feel uncomfortable when engaging in social interactionsB)They often find themselves in confrontation with their colleaguesC)They are unwilling to make efforts to maintain Workplace r elationshipsD)They lack basic communication skills in dealing with interpersonal issues50.What is one of the benefits of indifferent relationships?A)They provide fun at workB)They help control emotionsC)They help resolve differencesD)They improve work efficiencyPassage TwoQuestions 51 to 55 are based on the following passage.In a few decades, artificial intelligence (AI) will surpass many of the abilities that we believe make us special This is a grand challenge for our age and it may require an "irrational" responseOne of the most significant pieces of news from the US in early 2017 was the efforts of Google to make autonomous driving a reality. According to a report, Google’s self-driving cars clocked 1,023,330 krn, and required human intervention 124 times. That is one intervention about every 8,047 km of autonomous driving. But even more impressive is the progress in just a single year: human interventions fell from 0.8 times per thousand miles to 0.2, a 400% improvement. With such progress, Google’s cars will easily surpass my own driving ability later this year.Driving once seemed to be a very human skill. But we said that about chess, too. Then a computer beat the human world champion, repeatedly. The board game Go ( 围棋）took over from chess as a new test for human thinking in 2016, when a computer beat one of the world's lea小ng professional Go players. With computers conquering what used to be deeply human tasks, what will it mean in the future to be human? I worry about my six-year-old son. What will his place be in a world where machines beat us in one area after another? He'll never calculate faster, never drive better, or even fly more safely. Actually, it all comes down to a fairly simple questionWhat's so special about us? It can't be skills like arithmetic, which machines already excel in. So far, machines have a pretty hard time emulating creativity, arbitrary enough not to be predicted by a computer, and yet more than simple randomness.Perhaps, if we continue to improve information-processing machines, we’ll soon have helpful rational assistants. So we must aim to complement the rationality of the machine, rather than to compete with it. If I'm right, we should foster a creative spirit because a dose of illogical creativity will complement the rationality of the machine. Unfortunately, however, our education system has not caught up to the approaching reality. Indeed, our schools and universities are structured to mould pupils to be mostly obedient servants of rationality, and to develop outdated skills in interacting with outdated machines. We need to help our children learn how to best work with smart computers to improve human decision-making. But most of all we need to keep the long-term perspective in mind: that even if computers will outsmart us, we can still be the most creative. Because if we aren’t,we won’t be providing much value in future ecosystems, and that may put in question the foundation for our existence.51.What is the author's greatest concern about the use of AI?A)Computers are perfoming lots of creative tasksB)Many abilities will cease to be unique to human bemgsC)Computers may become more rational than humansD)Many human skills are fast becoming outdated52.What impresses the author most in the field of AI?A)Google's experimental driverless cars require little human interventionB)Google's cars have surpassed his driving ability in j ust a single yearC)Google has made huge progress in autonomous driving in a short timeD)Google has become a world leader in the field of a utonomous driving53.What do we learn from the passage about creativity?A)It is rat10nalB)It is predictableC)It is human specificD)It is yet to be emulated by AI54.What should schools help children do in the era of AI?A)Cultivate original thinkingB)Learn to work independentlyC)Compete with smart machinesD)Understand how AI works55.How can we humans justify our future existence?A)By constantly outsmarting computersB)By adopting a l ong-term perspectiveC)By r ationally c ompromising w ith A ID)By providing value with our creativityPart IV Translation (30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

However,as the cost of getting your own satellite in orbit drops sharply,the risks of irresponsible use grow.The question here is no longer“Can we?”but“Should we?”What are the potential downsides of having a slice of space densely populated by equipment built by people not traditionally labeled as“professionals”?And what would the responsible and beneficial development and use of this technology actually look like?Some of the answers may come from a nonprofit organization that has been building and launching amateur satellites for nearly50years.[C]Having your personal satellite launched into orbit might sound like an idea straight out of science fiction.But over the past few decades a unique class of satellites has been created that fits the bill:CubeSats.The“Cube”here simply refers to the satellite's shape.The most common CubeSat is a10cm cube,so small that a single CubeSat could easily be mistaken for a paperweight on your desk.These mini-satellites can fit in a launch vehicle's formerly“wasted space.”Multiples can be deployed in combination for more complex missions than could be achieved by one CubeSat alone.[D]Within their compact bodies these minute satellites are able to house sensors and communications receivers/transmitters that enable operators to study Earth from space,as well as space around Earth.They're primarily designed for Low Earth Orbit(LEO)-an easily accessible region of space from around200to800miles above Earth,where human-tended missions like the Hubble Space Telescope and the International Space Station(ISS)hang out.But they can attainmore distant orbits;NASA plans for most of its future Earth-escaping payloads(to the moon and Mars especially)to carry CubeSats.[E]Because they're so small and light,it costs much less to get a CubeSat into Earth's orbit than a traditional communications or GPS satellite.For instance,a research group here at Arizona State University recently claimed their developmental small CubeSats could cost as little as $3,000to put in orbit.This decrease in cost a11ows researchers,hobbyists and even elementary school groups to put simple instruments into LEO or even having them deployed from the ISS.[F]The first CubeSat was created in the early2000s,as a way of enabling Stanford graduate students to design,build,test and operate a spacecraft with similar capabilities to the USSR's Sputnik(前苏联的人造卫星).Since then,NASA,the National Reconnaissance Office and even Boeing have all launched and operated CubeSats.There arc more than130currently in operation. The NASA Educational Launch of Nano Satellite program,which offers free launches for educational groups and science missions,is now open to U.S.nonprofit corporations as well. Clearly,satellites are not just for rocket scientists anymore.[G]The National Academy of Sciences report emphasizes CubeSats'importance in scientific discovery and the training of future space scientists and engineers.Yet it also acknowledges that widespread deployment of LEO CubeSats isn't risk-flee.The greatest concern the authors raise is space debris-pieces of“junk”that orbit the earth,with the potential to cause serious damage if they collide with operational units,including the ISS.[H]Currently,there aren't many CubeSats and they're tracked closely.Yet as LEO opens up to more amateur satellites,they may pose an increasing threat.As the report authors point out, even near-misses might lead to the“creation of a burdensome regulatory framework and affect the future disposition of science CubeSats.”[I]CubeSat researchers suggest that now's the time to ponder unexpected and unintended possible consequences of more people than ever having access to their own small slice of space.In an era when you can simply buy a CubeSat kit off the shelf,how can we trust the satellites over our heads were developed with good intentions by people who knew what they were doing?Some “expert amateurs”in the satellite game could provide some inspiration for how to proceed responsibly.[J]In1969,the Radio Amateur Satellite Corporation(AMSAT)was created in order to foster ham radio enthusiasts'(业余无线电爱好者)participation in space research and communication.It continued the efforts,begun in1961,by Project OSCAR-a U.S.-based group that built and launched the very first nongovernmental satellite just four years after Sputnik.As an organization of volunteers,AMSAT was putting“amateur”satellites in orbit decades before the current CubeSat craze.And over time,its members have learned a thing or two about responsibility.Here, open.source development has been a central principle,Within the organization,AMSAT has a philosophy of open sourcing everything making technical data on all aspects of their satellites fully available to everyone in the organization,and when possible,the public.According to a member of the team responsible for FOX1-A,AMSAT's first CubeSat,this means that there s no way to sneak something like explosives or an energy emitter into an amateur satellite when everyone has access to the designs and implementation.[K]However,they're more cautious about sharing information with nonmembers,as the organization guards against others developing the ability to hijack and take control of their satellites.This form of“self-governance”is possible within long-standing amateur organizationsthat,over time,are able to build a sense of responsibility to community members,as well as society in general.But what happens when new players emerge,who don't have deep roots within the existing culture?[L]Hobbyists and students are gaining access to technologies without being part of a long-standing amateur establishment.They're still constrained by funders,launch providers and a series of regulations-all of which rein in what CubeSat developers can and cannot do.But there's a danger they're ill-equipped to think through potential unintended consequences.What these unintended consequences might be is admittedly far from clear.Yet we know innovators can be remarkably creative with taking technologies in unexpected directions.Think of something as seemingly benign as the cellphone-we have microfinance and text-based social networking at one end of the spectrum,and improvised(临时制作的)explosive devices at the other.[M]This is where a culture of social responsibility around CubeSats becomes important-not simply to ensure that physical risks are minimized,but to engage with a much larger community in anticipating and managing less obvious consequences of the technology.This is not an easy task. Yet the'evidence from AMSAT and other areas of technology development suggests that responsible amateur communities can and do emerge around novel technologies.The challenge here,of course,is ensuring that what an amateur communities considers to be responsible,actually is.Here's where there needs to be a much wider public conversation that extends beyond government agencies and scientific communities to include students,hobbyists,and anyone who may potentially stand to be affected by the use of CubeSat technology.36.Given the easier accessibility to space,it is time to think about how to prevent misuse of satellites.37.A group of mini-satellites can work together to accomplish more complex tasks.38.The greater accessibility of mini-satellites increases the risks of their irresponsible use.39.Even school pupils can have their CubeSats put in orbit owing to the lowered launching cost.40.AMSAT is careful about sharing information with outsiders to prevent hijacking of their satellites.41.NASA offers to launch CubeSats free of charge for educational and research purposes.42.Even with constraints,it is possible for some creative developers to take the CubeSat technology in directions that result in harmful outcomes.43.While making significant contributions to space science,CubeSats may pose hazards to other space vehicles.44.Mini-satellites enable operators to study Earth from LEO and space around it.45.AMSAT operates on the principle of having all its technical data accessible to its members,preventing the abuse of amateur satellites.Section CDirections:There are2passages in this section.Each passage is followed by some questions orunfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.When I re-entered the full-time workforce a few years ago after a decade of solitary self-employment,there was one thing I was looking forward to the most:the opportunity to have work friends once again.It wasn’t until I entered the corporate world that I realized,for me at least, being friends with colleagues didn’t emerge as a priority at all.This is surprising when you consider the prevailing emphasis by scholars and trainers and managers on the importance of cultivating close interpersonal relationships at work.So much research has explored the way in which collegial(同事的)ties can help overcome a range of workplace issues affecting productivity and the quality of work output such as team-based conflict,jealousy,undermining, anger,and more.Perhaps my expectations of lunches,water-cooler gossip and caring,deep-and-meaningful conversations were a legacy of the last time I was in that kind of office environment.Whereas now, as I near the end of my fourth decade,I realize work can be fully functional and entirely fulfilling without needing to be best mates with the people sitting next to you.In an academic analysis just published in the profoundly-respected Journal of Management, researchers have looked at the concept of“indifferent relationships”.It’s a simple term that encapsulates(概括)the fact that relationships at work can reasonably be non-intimate, inconsequential,unimportant and even,dare I say it,disposable or substitutable.Indifferent relationships are neither positive nor negative.The limited research conducted thus far indicates they’re especially dominant among those who value independence over cooperation,and harmony over confrontation.Indifference is also the preferred option among those who are socially lazy.Maintaining relationships over the long term takes effort.For some of us,too much effort.As noted above,indifferent relationships may not always be the most helpful approach in resolving some of the issues that pop up at work.But there are nonetheless several empirically proven benefits.One of those is efficiency.Less time chatting and socializing means more time working and churning(产出).The other is self-esteem.As human beings,we’re primed to compare ourselves to each other in what is an anxiety-inducing phenomenon.Apparently,we look down on acquaintances more so than friends.Since the former is most common among those inclined towards indifferent relationships,their predominance can bolster individuals’sense of self-worth.Ego aside,a third advantage is that the emotional neutrality of indifferent relationships has been found to enhance critical evaluation,to strengthen one’s focus on task resolution,and to gain greater access to valuable information.None of that might be as fun as after-work socializing but, hey,I’ll take it anyway.46.What did the author realize when he re-entered the corporate world?A)Making new friends with his workmates was not as easy as he had anticipated.B)Cultivating positive interpersonal relationships helped him expel solitary feelings.C)Working in the corporate world requires more interpersonal skills than self-employment.D)Building close relationships with his colleagues was not as important as he had expected.47.What do we learn from many studies about collegial relationships?A)Inharmonious relationships have an adverse effect on productivity.B)Harmonious relationships are what many companies aim to cultivate.C)Close collegial relationships contribute very little to product quality.D)Conflicting relationships in the workplace exist almost everywhere.48.What can be inferred about relationships at work from an academic analysis?A)They should be cultivated.B)They are virtually irrelevant.C)They are vital to corporate culture.D)They should be reasonably intimate.49.What does the author say about people who are socially lazy?A)They feel Uncomfortable when engaging in social interactions.B)They often find themselves in confrontation with their colleagues.C)They are Unwilling to make efforts to maintain Workplace relationships.D)They lack basic communication skills in dealing with interpersonal issues.50.What is one of the benefits of indifferent relationships?A)They provide fun at Work.B)They help control emotions.C)They help resolve differences.D)They improve Work efficiency.Passage TwoQuestions51to55are based on the following passage.In a few decades,artificial intelligence(AI)will surpass many of the abilities that we believe make us special.This is a grand challenge for our age and it may require an“irrational”response.One of the most significant pieces of news from the US in early2017was the efforts of Google to make autonomous driving a reality.According to a report,Google’s self-driving cars clocked1,023,330km,and required human intervention124times.That is one intervention about every8,047km of autonomous driving.But even more impressive is the progress in just a single year:human interventions fell from0.8times per thousand miles to0.2,a400%improvement. With such progress,Google’s cars will easily surpass my own driving ability later this year.Driving once seemed to be a very human skill.But we said that about chess,too.Then a computer beat the human world champion,repeatedly.The board game Go(围棋)took over from chess as a new test for human thinking in2016,when a computer beat one of the world’s leading professional Go players.With computers conquering what used to be deeply human tasks,what will it mean in the future to be human?I worry about my six-year-old son.What will his place bein a world where machines beat us in one area after another?He’ll never calculate faster,never drive better,or even fly more safely.Actually,it all comes down to a fairly simple question: What’s so special about us?It can’t be skills like arithmetic,which machines already excel in.So far,machines have a pretty hard time emulating creativity,arbitrary enough not to be predicted by a computer,and yet more than simple randomness.Perhaps,if we continue to improve information-processing machines,we’ll soon have helpful rational assistants.So we must aim to complement the rationality of the machine,rather than to compete with it.If I'm right,we should foster a creative spirit because a dose of illogical creativity will complement the rationality of the machine.Unfortunately,however,our education system has not caught up to the approaching reality.Indeed,our schools and universities are structured to mould pupils to be mostly obedient servants of rationality,and to develop outdated skills in interacting with outdated machines.We need to help our children learn how to best work with smart computers to improve human decision-making.But most of all we need to keep the long-term perspective in mind:that even if computers will outsmart us,we can still be the most creative.Because if we aren’t,we won’t be providing much value in future ecosystems,and that may put in question the foundation for our existence.51.What is the author’s greatest concern about the use of AI?A)Computers are performing lots of creative tasks.B)Many abilities will cease to be unique to human beings.C)Computers may become more rational than humans.D)Many human skills are fast becoming outdated.52.What impresses the author most in the field of AI?A)Google’s experimental driverless cars require little human intervention.B)Google’s cars have surpassed his driving ability in just a single year.C)Google has made huge progress in autonomous driving in a short time.D)Google has become a world leader in the field of autonomous driving.53.What do we learn from the passage about creativity?A)It is rational.B)It is predictable.C)It is human specific.D)It is yet to be emulated by AI.54.What should schools help children do in the era of AI?A)Cultivate original thinking.B)Learn to work independently.C)Compete with smart machines.D)Understand how AI works.55.How can we humans justify our future existence?A)By constantly outsmarting computers.B)By adopting a long-term perspective.C)By rationally compromising with AI.D)By providing value with our creativity.PartⅣTranslation(30minutes) Directions:For this part,you are allowed30minutes to translate a passage from Chinese into English.You should write your answer on Answer Sheet2.汉语现在是世界上用作本族语人数最多的语言。

2019年6月大学英语六级考试真题及参考答案（第1套）Part I Writing (30 minutes)Directions: For this part, you are allowed 30 minutes to write an essay on the importance of motivation and methods in learning.You should write at least 150 words but no more than 200 words.【参考范文】As an old saying goes, knowledge can change one’s life. In order to acquire knowledge, we have to study hard. However, it can not be ignored that effective learning needs both motivation and scientific methods.It’s not difficult for us to come up with se veral possible reasons accounting for this perspective. In the first place, learning is a kind of serious and hard work. Therefore, not everyone is able to keep going without certain internal motivations. Besides, scientific methods play a significant role in improving learning efficiency. Many of us believe that the longer you study, the better grades you will get. But a lot of experiences of our classmates prove that this view is not entirely correct. In details, studying for a long time is exhausting and it is very likely to decrease study efficiency, which is critical to academic performance.From what has been mentioned above, we can easily draw a conclusion that the importance of motivation and methods in learning is self-evident. And it is necessary for us to develop good learning methods.【参考范文译文】俗话说，知识能改变命运。
因此，为了获得知识，我们必须努力学习。
然而，不可忽略的是，有效的学习既离不开学习动力的存在，也离不开科学的学习方法。
不难列举上述观点的原因。
首先，学习是一件严肃且困难的事。
因此，不是每个人都能在没有某种内在动机的情况下一直继续。
此外，科学的方法在提高学习效率方面发挥着重要的作用。
我们当中有不少人都认为，学习的时间越长，成绩就会越好。
但是我们周边同学的很多经历证明这个观点并不完全正确。
具体来说，长时间的学习是累人的，因此它很可能会降低学习效率，而学习效率对于学业成绩来说却是至关重要的。
综上所述，我们可以很容易就得出如下结论：学习动机和方法的重要性是不言而喻的，因此我们非常有必要形成良好的学习方法。

For years, nutritionists have recommended that pasta be kept to a 26 , to cut calories, prevent fat build-up and stop blood sugar 27 up.The low-carbohydrate food movement gave birth to such diets as the Atkins, Paleo and Keto, which advised swapping foods like bread, pasta and potatoes for vegetables, fish and meat. More recently the trend of swapping spaghetti for vegetables has been 28 by clean-eating experts.But now a 29 review and analysis of 30 studies by Canadian researchers found that not only does pasta not cause weight gain, but three meals a week can help people drop more than half a kilogram over four months. The reviewers found that pasta had been unfairly demonized (妖魔化) because it had been 30 in with other, more ft-promoting carbohydrates.“The study found that pasta didn’t 3 to weight gain or increase in body fat,” said lead author Dr John Sievenpiper. “In 32 the evidence, we can now say with some confidence that pasta does not have an 33 effect on body weigh outcomes when it is consumed as part of a healthy dietary pattern.” In fact, analysis actually showed a small weigh loss 34 to concerns. perhaps pasta can be part of a healthy dietThose involved in the 35 trials on average ate 3.3 servings of pasta a week instead of other carbohydrates, one serving equaling around half acup.

Stores are closing. Malls are emptying. The depressing stories just keep coming. Reading the earnings announcements of large retail stores like Macy’s, Nordstrom, and Target is about as uplifting as a tour of an intensive care unit. The interact is apparently taking down yet another industry. Brick and mortar stores (实体店) seem to be going the way of the yellow pages. Sure enough, the Census Bureau just released data showing that online retail sales surged 15.2 percent between the first quarter of 2015 and the first quarter of 2016.B) But before you dump all of your retail stocks, there are more facts you should consider. Looking only at that 15.2 percent "surge" would be misleading. It was an increase that was on a small base of 6.9 percent. Even when a tiny number grows by a large percentage terms, it is often still tiny.C) More than 20 years after the internet was opened to commerce, the Census Bureau tells us that brick and mortar sales accounted for 92.3 percent of retail sales in the first quarter of 2016. Their data show that only 0.8 percent of retail sales shifted from offline to online between the beginning of 2015 and 2016.D) So, despite all the talk about drone (无人机) deliveries to your doorstep, all the retail executives expressing anxiety over consumers going online, and even a Presidential candidate exclaiming that Amazon has a "huge antitrust problem," the Census data suggest that physical retail is thriving. Of course, the closed stores, depressed executives, and sinking stocks suggest otherwise. What's the real story?E) Many firms operating brick and mortar stores are in trouble. The retail industry is getting reinvented, as we describe in our new book Matchmakers. It's standing in the Path of what Schumpeter called a gale (大风) of creative destruction. That storm has been brewing for some time, and as it has reached gale force, most large retailers are searching for a response. As the CFO of Macy’s put it recently, “We’re frankly scratching our heads.”F) But it’s not happening as experts predicted. In the peak of the dot. com bubble, brick and mortar retail was one of those industries the internet was going to kill-and quickly. Thedot.corn bust discredited most predictions of that sort and in the years that followed, onventional retailers’ confidence in the future increased as Census continued to report weak online sales. And then the gale hit.G) It is becoming increasingly clear that retail reinvention isn’t a simple battle to the death between bricks and clicks. It is about devising retail models that work for people who are making increasing use of a growing array of internet-connected tools to change how they search, shop, and buy. Creative retailers are using the new technologies to innovate just about everything stores do from managing inventory, to marketing, to getting paid.H) More than drones dropping a new supply of underwear on your doorstep, Apple’s massively successful brick-and-mortar-and-glass retail stores and Amazon’s small steps in the same direction are what should keep old-fashioned retailers awake at night. Not to mention the large number of creative new retailers, like Bonobos, that are blending online and offline experiences in creative ways.I) Retail reinvention is not a simple process, and it’s also not happening on what used to be called "Internet Time." Some internet-driven changes have happened quickly, of course. Craigslist quickly overtook newspaper classified ads and turned newspaper economics upside down. But many widely anticipated changes weren’t quick, and some haven’t really started. With the benefit of hindsight (后见之明), it looks like the interact will transform the economy at something like the pace of other great inventions like electricity. B2B commerce, for example, didn’t move mainly online by 2005 as many had predicted in 2000, nor even by 2016, but that doesn’t mean it won’t do so over the next few decades.J) But the gale is still blowing. The sudden decline in foot traffic in recent years, even though it hasn’t been accompanied by a massive decline in physical sales, is a critical warning. People can shop more efficiently online and therefore don’t need to go to as many stores to find what they want. There’s a surp lus of physical shopping space for the crowds, which is one reason why stores are downsizing and closing.K) The rise of the mobile phone has recently added a new level of complexity to the process of retail reinvention. Even five years ago most people faced a choice. Sit at your computer, probably at home or at the office, search and browse, and buy. Or head out to the mall, or Main Street, look and shop, and buy. Now, just about everyone has a smartphone, connected to the internet almost everywhere almost all the time. Even when a retailer gets a customer to walk in the store, she can easily see if there’s a better deal online or at another store nearby.L) So far, the main thing many large retailers have done in response to all this is to open online stores, so people will come to them directly rather than to Amazon and its smaller online rivals．Many are having the same problem that newspapers have. Even if they get online traffic, they struggle to make enough money online to compensate for what they are losing offline.M) A few seem to be making this work．Among large traditional retailers, Walmart recently reported the best results, leading its stock price to surge, while Macy’s, Target, and Nordstrom’s dropped. Yet Walmart’s year-over-year online sales only grew 7 percent, leading its CEO to lament (哀叹), “Growth here is too slow．”Part of the problem is that almost two decades after Amazon filed the one．click patent, the online retail shopping and buying experience is filled with frictions．A recent study graded more than 600 internet retailers on how easy it was for consumers to shop, buy, and pay．Almost half of the sites didn’t get a passing grade and only 18 percent got an A or B．N) The turmoil on the ground in physical retail is hard to square with the Census data． Unfortunately, part of the explanation is that the Census retail data are unreliable．Our deep 100k into those data and their preparation revealed serious problems．It seems likely that Census simply misclassifies a large chunk of online sales．It is certain that the Census procedures, which lump the online sales of major traditional retailers like Walmart with“non-store retailers"1ike food trucks．can mask major changes in individual retail categories．The bureau could easily present their data in more useful ways．but they have chosen not to.O) Despite the turmoil, brick and mortar won’t disappear any time soon．The big questions are which, if any, of the large traditional retailers will still be on the scene in a decade or two because they have successfully reinvented themselves, which new players will operate busy stores on Main Streets and maybe even in shopping malls, and how the shopping and buying experience will have changed in each retail category.Investors shouldn’t write off brick and morta r. Whether they should bet on the traditional players who run those stores now is another matter36.Although online retailing has existed for some twenty years, nearly half of the internet retailers still fail to receive satisfactory feedback from consumers, according to a recent survey．37.Innovative retailers integrate internet technologies with conventional retailing to create new retail models．38.Despite what the Census data suggest, the value of physical retail’s stocks has been dropping．39.Innovative—driven changes in the retail industry didn’t take place as quickly as widely anticipated．40. Statistics indicate that brick and mortar sales still made up the lion’s share of the retail business.41. Companies that successfully combine online and offline business models may prove to be a big concern for traditional retailers.42.Brick and mortar retailers’ faith in their business was strengthened when the dot com bubble burst.43. Despite the tremendous challenges from online retailing, traditional retailing will be here to stay for quite some time.44. With the rise of online commerce, physical retail stores are likely to suffer the same fate as i the yellow pages.45. The wide use of smartphones has made it more complex for traditional retailers to reinvent their business.36-40 M G D I C41-45 H F O A KSection 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).

So it;s a welcome change that people are studying instead the future of intelligence.”While the world-renowned physicist has often been cautious about AI, raising concerns that humanity could be the architect of its own destruction if it creates a super-intelligence with a will of its own, he was also quick to highlight the positives that AI research can bring. “The potential benefits of creating intelligence are huge,” he said. “We cannot predict what we might achieve when our own minds are amplified by AI. Perhaps with the tools of this new technological revolution, we will be able to undo some of the damage done to the natural world by the last one-industrialisation. And surely we will aim to finally eradicate disease and poverty. And every aspect of our lives will be transformed. In short, success in creating AI could be the biggest event in the history of our civilization.”Huw Price, the centre’s academic director and the Bertrand Russell professor of philosophy at Cambridge University, where Hawking is also an academic, said that the centre came about partially as a result of the university’s Centre for Exist ential Risk. That institute examined a wider range of potential problems for humanity, while the LCFI has a narrow focus.AI pioneer Margaret Boden, professor of cognitive science at the University of Sussex, praised the progress of such discussions. As re cently as 2009, she said, the topic wasn’t taken seriously, even amongAI researchers. “AI is hugely exciting,” she said, “but it has limitations, which present grave dangers given uncritical use.”The academic community is not alone in warning about the potential dangers of AI as well as the potential benefits. A number of pioneers from the technology industry, most famously the entrepreneur Elon Musk, have also expressed their concerns about the damage that a super-intelligent AI could do to humanity.46. What did Stephen Hawking think of artificial intelligence?A) It would be vital to the progress of human civilisation.B) It might be a blessing or a disaster in the making.C) It might present challenges as well as opportunities.D) It would be a significant expansion of human intelligence.47. What did Hawking say about the creation of the LCFI?A) It would accelerate the progress of AI research.B) It would mark a step forward in the AI industry.C) It was extremely important to the destiny of humankind.D) It was an achievement of multi-disciplinary collaboration.48. What did Hawking say was a welcome change in AI research?A) The shift of research focus from the past to the future.B) The shift of research from theory to implementation.C) The greater emphasis on the negative impact of AI.D) The increasing awareness of mankind’s past stupidity.49. What concerns did Hawking raise about AI?A) It may exceed human intelligence sooner or later.B) It may ultimately over-amplify the human mind.C) Super-intelligence may cause its own destruction.D) Super-intelligence may eventually ruin mankind.50. What do we learn about some entrepreneurs from the technology industry?A) They are much influenced by the academic community.B) They are most likely to benefit from AI development.C) They share the same concerns about AI as academics.D) They believe they can keep AI under human control.Passage TwoQuestions 51 to 55 are based on the following passage.The market for products designed specifically for older adults could reach $30 billion by next year, and startups (初创公司) want in on the action. What they sometimes lack is feedback from the people who they hope will use their products. So Brookdale, the country’s largest owner of retirement communities, has been inviting a few select entrepreneurs just to move in for a few days, show off their products and hear what the residents have to say.That’s what brought Dayle Rodriguez, 28, all the way from England to the dining room of Brookdale South Bay in Torrance, California. Rodriguez is the community and marketing manager for a company called Sentab. The startup’s product, SentabTV, enables older adults who may not be comfortable with computers to access email, video chat and social media using just their televisions and a remote control.“It’s nothing new, it’s nothing too complicated and it’s natural because lots of people have TV remotes,”says Rodriguez.But none of that is the topic of conversation in the Brookdale dining room. Instead, Rodriguez solicits resi dents’ advice on what he should get on his cheeseburger and how he should spend the afternoon. Playing cards was on the agenda, as well as learning to play mahjong (麻将).Rodriguez says it’s important that residents here don’t feel like he’s selling them so mething. “I’ve had more feedback in a passive approach,”he says. “Playing pool, playing cards, having dinner, having lunch,”all work better “than going through a survey of questions. When they get to know me and to trust me, knowing for sure I’m not sellin g them something—there’ll be more honest feedback from them.”Rodriguez is just the seventh entrepreneur to move into one of Brookdale’s 1,100 senior living communities. Other new products in the program have included a kind of full-body blow dryer and specially designed clothing that allows people with disabilities to dress and undress themselves.Mary Lou Busch, 93, agreed to try the Sentab system.hse She tells Rodriguez that it might be good for someone, but not for her.“I have the computer and FaceTime, which I talk with my family on,”she explains. She also has an iPad and a smartphone. “So I do pretty much everything I need to do.”To be fair, if Rodriguez had wanted feedback from some more technophobic (害怕技术的) seniors, he might have ended up in the wrong Brookdale community. This one is located in the heart of Southern California’s aerospace corridor. Many residents have backgrounds in engineering, business and academic circles.But Rodriguez says he's still learning something important by moving into this Brookdale community: “People are more tech-proficient than we thought.”And besides, where else would he learn to play mahjong?51. What does the passage say about the startups?A) They never lose time in upgrading products for seniors.B) They want t o have a share of the seniors’ goods market.C) They invite seniors to their companies to try their products.D) They try to profit from promoting digital products to seniors.52. Some entrepreneurs have been invited to Brookdale toA) have an interview with potential customersB) conduct a survey of retirement communitiesC) collect residents’ feedback on their productsD) show senior residents how to use IT products53. What do we know about SentabTV?A) It is a TV program catering to the interest of the elderly.B) It is a digital TV which enjoys popularity among seniors.C) It is a TV specially designed for seniors to view programs.D) It is a communication system via TV instead of a computer.54. What does Rodriguez say is important in promoting products?A) Winning trust from prospective customers.B) Knowing the likes and dislikes of customers.C) Demonstrating their superiority on the spot.D) Responding promptly to customer feedback.。
