2018年6月英语六级详细参考答案（全三套）2018年6月丨六级听力1听力第一套Section AConversation OneM: What's all that? Are you going to make a salad?W: No I'm going to make a gazpacho.M: What's that?W: Gazpacho is a cold soup from Spain. It’s mostly vegetables. I guess you could call it a liquid salad.M: Cold soup? Sounds weird.W: It's delicious. Trust me. I tried it for the first time during my summer vacation in Spain. You see, in the south of Spain, it gets very hot in the summer, up to 40°C.So acold gazpacho is very refreshing. The main ingredients are tomato, cucumber, bell peppers, olive oil and stale bread.M: Stale bread? Surely you mean bread for dipping into the soup?W: No. Bread is crushed and blended in like everything else. It adds texture and thickness to the soup.M: Mm. And is it healthy?W: Sure. As I said earlier it's mostly vegetables. You can also add different things if you like, such as hard-boiledegg or cured ham.M: Cured ham? What’s that?W: That's another Spanish delicacy. Have you never heard of it? It is quite famous. M: no, is it good too?W: Oh, yeah, definitely. It’s amazing. It’s a little dry and salty, and it's very expensive because it comes from a special type ofpigthat only eats a special type of food. The harm is covered in salt to dry and preserve it. And left to hang for up to 2 years, it has a very distinct flavor.M: Mm. Sounds interesting. Where can I find some?W: Itusedto be difficult to get Spanish produce here. But it's now a lot more common. Most large supermarket chains have cured ham in little packets but in Spain you combine a whole leg.M: A whole peg leg? Why would anybody want so much ham?W: In Spain, many people buy a whole leg for special group events, such as Christmas. They cut it themselves into very thin slices with a long flat knife.Questions 1 to 4 are based on the conversation you have just heard.1. What do we learn about gazpacho?2. For what purpose is stale bread mixed into gazpacho?3. Why does the woman think gazpacho is healthy?4. What does the woman say about cured ham?Conversation TwoM: Hello, I wish to buy a bottle of wine.W: Hi, yes. What kind of wine would you like?M: I don't know, sorry. I don't know much about wine.W: That’s no problem at all. What’s the occasion and how much would you like to spend?M: It's for my boss. It’s his birthday. I know he likes wine, but I don't know what type.I also do not want anything too expensive, maybe mid-range. How much would you say is a mid-range bottle of wine approximately?W: Well, it varies greatly. Our lowest prices are around $6 a bottle, but those are table wines. They are not very special. And I would not suggest them as a gift. On the other end, our most expensive bottles are over $150. If you are looking for something priced in the middle, I would say anything between $30 and $60 would make a decent gift. How does that sound?M: Mm, yeah. I guess something in the vicinity of 30 or 40 would be good. Which type would you recommend?W: I would say the safest option is always a red wine. They are generally more popular than whites, and can usually be paired with food more easily. Our specialty here are Italian wines, and these tend to be fruity with medium acidity. This one here is a Chianti,which is perhaps Italy's most famous type of red wine. Alternatively, you may wish to try and surprise your boss with something less common, such as the Infantile. The grapes are originally native to Croatia but this winery is in east in Italy and it has a more spicy and peppery flavor. So to summarize, the Chianti is more classical and the Infantile more exciting. Both are similarly priced at just under $40.M: I will go with Chianti then. Thanks.Questions 5 to 8 are based on the conversation you have just heard.5. What does the woman think of table wines?6. What is the price range of wine the man will consider?7. Why does the woman recommend red wines?8. What do we learn about the wine the man finally bought?Section BPassage OneMany people enjoysecretcodes, the harder the code the more some people would try to figure it out. In war time, codes are especially important, they help army sendnews about battles and signs of enemy forces. Neither side wants its code broken by the other. One very important code was never broken, it was used during world war two by the Americans. It was spoken code, never written down and it was developed and used by NH Indians. They were called the NH code talkers. The NH created the codes in their own language. NH was hard to learn and only a few people know it. So it was pretty certain that the enemy would not be able to understand the code talkers. In addition, the talkers used code words. They called a submarine and an iron fish and a small bomb thrown by hand, a potato. If they wanted to spell something, they used code words for letters of the Alphabet. For instance, the letter A was ant orappleor ax, the code talkers worked mostly in the islands in the Pacific. One or two would be assigned a group of soldiers. They would send messages by field telephone to the code talker in the next group. And he would relay the information to his commander. The code talkers played an important part in several battles. They helped the troops coordinate their movements and attacks. After the war, the US governments honored them for what they had accomplished. Theirs was the most successful wartime codeever used.Questions 9 to 11 are based on the passage you have just heard.9 . What does the speaker say many people enjoy doing?10.What do we learn about the NH talkers?11.What is the speaker mainly talking about?Passage TwoIf you are young and thinking about your career, you want to know where you can make a living, well, this going to be a technological replacement of a lot of knowledge intensive jobs in the next twenty years. Particularly in the two largest sectors of the labor force with professional skills. One is teaching, and the other, health care. You have so many applications and software and platforms, but going to come in and provide information and service in these two fields, which means a lot of health care and education sectors, would be radically changed, and lots of jobs will be lost. Now, where will the new jobs be found, well the one sector of the economy that can't be easily duplicated by even small technologies is the caring sector, the personal care sector, that is, you can't really get a robot to do a great massage or physical therapy. Or, you can't get the kind of personal attention you need with regard to therapy or any other personal service. There could be very high and personal services, therapist do charge a lot of money, I think there's no limit to the amount of personal attention and personal care, people would like if they could afford it. But, the real question in the future is, how come people afford these things if they don't have money, because they can't get a job that pays enough, that's why I wrote this book, which is about how to reorganize the economy for the future when technology brings about destructive changes, to what we used to consider high income work.Questions 12 to 15 are based on the passage you have just heard.12. What does the speaker say will happen in the next twenty years?13. Where will young people have more chances to find jobs?14. What does the speaker say about therapist?15. What is the speaker’s book about?Section CRecording OneAmerican researchers have discovered the world's oldest paved road, a 4,600-year-old highway. It linked a stone pit in the Egyptian desert to waterways that carried blocks to monument sites along the Nile. The eight-mile road is at least 500 years older than any previously discovered road. It is the only paved road discovered in ancient Egypt, said geologist Thomas Bown of the United States Geological Survey. He reported the discovery on Friday. "The road probably doesn't rank with the pyramids as a construction feat, but it is a major engineering achievement," said his colleague, geologist James Harrell of the University of Toledo. "Not only is the road earlier than we thought possible, we didn't even think theybuiltroads." The researchers also made a discovery in the stone pit at the northern end of the road: the first evidence that the Egyptians used rock saws. "This is the oldest example of saws being used for cutting stone," said Bown’s colleague James Hoffmeier of Wheaton College in Illinois. "That's two technologies we didn't know they had," Harrell said "And we don't know why they were both abandoned." The road was discovered in the Faiyum Depression, about 45 miles southwest of Cairo. Short segments of the road had been observed by earlier explorers, Bown said, but they failed to realize its significance or follow up on their observations. Bown and his colleagues stumbled across it while they were doing geological mapping in the region. The road was clearly built to provide services for the newly discovered stone pit. Bown and Harrell have found the camp that housed workers at the stone pit. The road appears today to go nowhere, ending in the middle of the desert. When it was built, its terminal was a dock on the shore of Lake Moeris, which had an elevation of about 66 feet above sea level, the same as the dock. Lake Moeris received its water from the annual floods of the Nile. At the time of the floods, the river and lake were at the same level and connected through a gap in the hills near the modern villages of el-Lahun and Hawara. Harrell and Bown believe that blocks were loaded onto barges during the dry season, then floated over to the Nile during the floods to be shipped off to the monument sites at Giza and Saqqara.Questions 16 to 18 are based on the recording you have just heard.16. What do we learn from the lecture about the world’s oldest paved road in Egypt?17. What did the researchers discover in the stone pit?18. For what purpose was the paved road built?Recording TwoThe thin, extremely sharp needles didn’t hurt at all going in. Dr. Gong pierced them into my left arm, around the elbow that had been bothering me. Other needles were slipped into my left wrist and, strangely, into my right arm, and then into both my closed eyelids.There wasn’t any discomfort, just a mild warming sensation. However, I did begin to wonder what had driven me here, to the office of Dr. James Gong, in New York’s Chinatown.Then I remembered－－the torturing pain in that left elbow. Several trips to a hospital and two expensive, uncomfortable medical tests had failed to produce even a diagnosis.“Maybe you lean on your left arm too much,”the doctor concluded, suggesting I see a bone doctor.During the hours spent waiting in vain to see a bone doctor, I decided to take another track and tryacupuncture. A Chinese-American friend recommended Dr. Gong. I took the subway to Gong’s second-floor office, marked with a hand-painted sign.Dr. Gong speaks English, but not often. Most of my questions to him were greeted with a friendly laugh, but I managed to let him know where my arm hurt. He asked me to go into a room, had me lie down on a bed, and went to work. In the next room, I learned, a woman dancer was also getting a treatment. As I lay there a while, I drifted into a dream-like state and fantasized about what she looked like.Acupuncturists today are as likely to be found on Park Avenue as on Mott Street. In all there are an estimated 10,000 acupuncturists in the country. Nowadays, a lot of M.D.s have learned acupuncture techniques; so have a number of dentists. Reason? Patient demand. Few, though, can adequately explain how acupuncture works. Acupuncturists may say that the body has more than 800 acupuncture points. A life force called qi circulates through the body. Points on the skin are energetically connected to specific organs, body structures and systems. Acupuncture points are stimulated to balance the circulation of qi.The truth is, though acupuncture is at least 2,200 years old,“nobody really knows what’s happening,”says Paul Zmiewski, a Ph.D. in Chinese studies who practices acupuncture in Philadelphia.After five treatments, there has been dramatic improvement in my arm, and the pain is a fraction of what it was. The mainly silent Dr. Gong finally even offered a diagnosis for what troubled me.“Pinched nerve,”he said.Questions 19 to 21 are based on the recording you have just heard.19. What does the speaker find especially strange?20. Why did the speaker go see Dr. Gong?21. What account for the growing popularity ofacupuncturein the United States, according to the speaker?Recording ThreeRonald and Lois married for two decades considered themselves a happy couple. But in the early years of their marriage both were distilled by persistent arguments that seem to fade away without ever being truly resolved. They uncovered clues to what was going wrong by researching a fascinating subject. How birth order affects not only your personality but also how compatible you are with your mate. Ronald and Lois are only children and onlies grow up accustomed to being the apple of parents’ eyes. Match two onlies and you have partners to sub consciously expect each other to continue fulfilling this expectation while neither has much experience in the giving and here's a list of common birth order characteristics and some thoughts on the best and worst Marischal matches for each. The oldest tends to be self-assured, responsible, a high achiever and relatively seriously reserved. He may be slow to make friends. Perhaps content with only one companion. The best matches are with a youngest and only or a mate raised in a large family. The worst match is with another oldest since the two will be too sovereign to share a household comfortably. The youngest child of the family thrives on the tension and tends to be outgoing, adventurous, optimistic, creative and less ambitious than others in the family. He may lack self-discipline and have difficulty making decisions on his own. A youngest brother of brothers often unpredictable and romantic will match best with an oldest sister of brothers. Theyoungest sister of brothers is best matched with the oldest brother of sisters who will happily indulge these traits. The middle child is influenced by many variables however middles are less likely to take initiative and more anxious and self-critical than others. Middles often successfully marry other middles. Since both are strong on tact not so strong on the aggressiveness and tend to crave affection. The only child is often most comfortable when alone. But since an only tends to be a well-adjusted individual she'll eventually learn to relate to any chosen spouse. The male only child expects his wife to make life easier without getting much in return. He is sometimes best matched with the younger sister of brothers. The female only child who tends to be slightly more flexible is well matched with an older man who will indulge her tendency to test his love—her worst much. Another only of course.Questions 22 to 25 are based on the recording you have just heard.22. What does the speaker say about Ronald and Lois's early years of married life?23. What do we learn about Ronald and Lois?24. What does the speaker say about the oldest child in the family?25.

Each statement contains information given in one of the paragraphs. Identify theparagraph from which the information is derived. You may choose a paragraph more thanonce. Each paragraph is marked with a letter.Answer the questions by marking thecorresponding letter on Answer Sheet 2.In the real world, nobody cares that you went to an Ivy League schoolA) As a high school junior, everything in my life revolved around getting into the right college.I diligently attended my SAT, ACT, and Advanced Placementtest preparation courses. Ijuggled (尽力应付) cross-country and track schedules, newspaper staff, and my church's youthgroup and drama team. I didn't drink, party, or even do much dating. The right college, Ithought, was one with prestige, one with a name. It didn't haveto be the Ivy League, but itneeded to be a "top school."B) Looking back now, nine years later, I can't remember exactly what it was about theseuniversities that made them seem so much better. Was it a curriculum that appeared morerigorous, perhaps? Or an alumni network that I hoped would open doors down the line?Maybe."I do think there are advantages to schools with more recognition," notes M arybethGasman, a professor of higher education at the University of Pennsylvania. "I don'tnecessarily think that's a reason to go to one."C) In reflection, my firm belief in the power of the brand was naive, not tomention a bitsnobby. I quickly passed over state schools and southern schools, believing their curriculumsto be automatically inferior to northeastern orwestern counterparts. Instead, I dreamed ofliving in New York City and my parents obliged me with a visit to New York University's (NYU)campus. Duringthe tour, tuition fees were discussed.(NYU is consistently ranked one of thecountry's most expensive schools, with room and board costs totaling upwards of $ 64,000 ayear.) Up until then, Ihadn't truly realized just how expensive an education can be. Over thenext few months, I realized not only could I not afford my dream school, I couldn't evenafford the ones where I'd been accepted. City University of New York (CUNY), RutgersUniversity, and Indiana University were out of reach as were Mississippi State and theUniversity of Alabama, where I would have to pay out-ofstate fees. Further complicating mycollege search was a flourishing track career—I wanted to keep running but my timesweren't quite fast enough to secure a scholarship.D) And so, at 11 pm on the night of Georgia State University's (GSU) midnight deadline, Iapplied online. Rated No.466 overall on Forbes' Lists Top Colleges, No.183 in ResearchUniversities, and No.108 in the South, I can't say it was my top choice. Still, the trackcoach had offered me a walk-on spot, and I actually found the urban Atlanta campus ad ecent consolation prize after New York City.E) While it may have been practical, it wasn't prestigious. But here's the thi ng: I loved my"lower-tier" (低层次的) university.(I use the term "low-tier" cautiously, because GSU is a well-regarded researc h institution that attracts high quality professors and faculty from all overth e country.) We are taught to believe that only by going to the best schools an d getting thebest grades can we escape the rat race and build a better future . But what if lower-tiercolleges and universities were the ticket to escaping th e rat race? After all, where else canyou leave school with a decent degree—b ut without a lifetime of debt?F) My school didn't come prepackaged like the more popular options, so we were left to takecare of ourselves, figuring out city life and trying to complete degree programs that no onewas championing for us to succeed in. What I'm saying is, I loved my university because ittaught us all to be resourceful and we could make what we wanted out of it.G) I was lucky enough to have my tuition covered by a lottery-funded schola rship calledHOPE (Helping Outstanding Pupils Educationally). When I started c ollege, the HOPEscholarship was funded by the state of Georgia and offered t o graduating high school seniorswith a GPA of 3.0 or higher. Living costs and books I paid for with money earned during highschool, supplemented by a sm all college fund my deceased grandfather left for me and amodest savings ac count my parents created when I was born.H) So what about all that name recognition? Sure, many of my colleagues a nd competitorshave more glamorous alma maters (母校) than I do. As a journalist, I have competed againstNYU, Columbia, and No rtheastern graduates for jobs. And yet, not a single interviewer hasever asked me about my educational background. In fact, almost every interview I've e verhad was due to a connection—one that I've gained through pure determi nation, not a schoolbrand.I) According to The Boston Globe, students who earned their bachelor's in 2012 have anaverage monthly loan payment of $312, which is one-third more than those who graduatedin 2004. Ultimately, that's the thing universities do n't want to admit. Private universities aremoney-making institutions. If you ca n afford to buy prestige, that's your choice. For the restof us, however, our h earty lower-tiered universities are just fine, thank you.J) Wealthy universities talk up the benefits their name will give graduates: na mely, strongalumni networks, star faculty, and a résuméboost. But you nee dn't attend an Ivy Leagueschool to reap those rewards. Ludacris and the for mer CEO of Bank of America Ken Lewis arealumni of my college, as well as VI CE's first female editor-in-chief, Ellis Jones. Successfulpeople tend to be successful no matter where they go to school, and lower-tier schools canhave alu mni networks just as strong as their big name counterparts. In fact, lower-tie r schoolalumni networks are arguably stronger, because fellow alumni recog nize that you didn'tnecessarily have an easy path to follow. They might be m ore willing to offer career help,because your less famous school denotes that , like them, you are also full of energy andperseverance.K) The Washington Post reported on a recent study by Princeton economists, i n which collegegraduates who applied to the most selective schools in the 12 th grade were compared tothose who applied to slightly less selective schoo ls. They found that students with morepotential earned more as adults, and the reverse held true as well, no matter where theywent to school.L) Likewise, star faculty are not always found where you'd expect. Big name s chools are notnecessarily the best places for professors; plus, many professor s split teaching time betweenmultiple colleges and/or universities. This mea ns, for instance, a CUNY student couldreasonably expect to receive the same quality of instruction from a prestigious professoras they would if they were enrolled in the same class at NYU.M) It's possible that some hiring managers may be drawn to candidates with a particulareducational résumé, but it's no guarantee. According to a 2012 survey described in TheAtlantic, college reputation ranked lowest in relative importance of attributes in evaluatinggraduates for hire, beaten out by top fa ctors like internships, employment during college,college major, volunteer ex perience, and extracurriculars.N) Maybe students who choose less prestigious universities are bound to suc ceed becausethey are determined to. I tend to think so. In any case, if I co uld do it again, I'd still makethe same choice. Today I'm debt-free, resourcef ul—and I understand that even theshiniest packaging can't predict what you'll find on the inside.36. Modest institutions can also have successful graduates and strong alumni networks.37. The money the author made in high school helped pay for her living expe nses and booksat college.38. The author came to see how costly college education could be when she was trying tochoose a university to attend.39. A recent study found that a graduate's salary is determined by their pot ential, not theuniversity they attended.40. The author cannot recall for sure what made certain top universities app ear a lot better.41. None of the author's job interviewers cared which college she went to.42. The author thinks she did the right thing in choosing a less prestigious u niversity.43. In order to be admitted to a prestigious university, the author took partin variousextracurricular activities and attended test preparation courses. 44. The author liked her university which was not prestigious but less expensive.45. Colleges are reluctant to admit that graduates today are in heavier debt.Section CDirections: There are 2 passages in this section. Each passage is followed by some questionsor unfinished statements. For each of them there are four choices marked A), B), C) andD). You should decide on the best choice and markthe corresponding letter on Answer Sheet2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Economically speaking, are we better off than we were ten years ago? Twentyyears ago?In their thirst for evidence on this issue, commentators seized on the recentreport by theCensus Bureau, which found that average household income rose by 5.2% in 2015.Unfortunately, that conclusion puts too much weight on auseful, but flawed andincomplete, statistic. Among the more significant problems with the Census's measure arethat:1) it excludes taxes, transfers, and compensation like employer-provided healthinsurance; and 2) it is based on surveys rather than data. Even if precisely measured,income data exclude important determinants of economic wellbeing, such as the hours ofwork needed to earn that income.While thinking about the question, we came across a recently published article by CharlesJones and Peter Klenow, which proposes an interesting new measure of economic welfare.While by no means perfect, it is considerably morecomprehensive than average income,taking into account not only growth inconsumption per person but also changes in workingtime, life expectancy, and inequality. Moreover, it can be used to assess economicperformance both across countries and over time.The Jones-Klenow method can be illustrated by a cross-country example. Suppose we wantto compare the economic welfare of citizens of the U.S. and France in 2005.In 2005, as the authors observe: real consumption per person in France wasonly 60% ashigh as the U.S., making it appear that Americans were economically much better off thanthe French on average. However, that comparisonomits other relevant factors: leisuretime, life expectancy, and economic inequality. The French take longer vacations and retireearlier, so typically workfewer hours; they enjoy a higher life expectancy, presumablyreflecting advantages with respect to health care, diet, lifestyle, and the like; and income andconsumption are somewhat more equally distributed there than in the U.S. Because of thesedifferences, comparing France's consumption with the U.S.'s overstates the gap in economicwelfare.Similar calculations can be used to compare the U.S. and other countries. Forexample, thiscalculation puts economic welfare in the United Kingdom at 97% of U.S. levels, butestimates Mexican well-being at 22%.The Jones-Klenow measure can also assess an economy's performance over time.According to this measure, as of the early-to-mid-2000s, the U.S. had the highest economicwelfare of any large country. Since 2007, economic we lfare in the U.S. has continued toimprove. However, the pace of improvement has slowed markedly.Methodologically, the lesson from the Jones-Klenow research is that economic welfare ismulti-dimensional. Their approach is flexible enough that in pri nciple other importantquality-of-life changes could be incorporated-for exa mple, decreases in total emissions ofpollutants and declines in crime rates.46. What does the author think of the 2015 report by the Census Bureau?A) It is based on questionable statistics.B) It reflects the economic changes.C) It evidences the improved-welfare.D) It provides much food for thought.47. What does the author say about the Jones-Klenow method?A) It is widely used to compare the economic growth across countries.B) It revolutionizes the way of measuring ordinary people's livelihood.C) It focuses on people's consumption rather than their average income.D) It is a more comprehensive measure of people's economic well-being.48. What do Jones and Klenow think of the comparison between France and the U. S. interms of real consumption per person?A) It reflected the existing big gap between the two economies.B) It neglected many important indicators of people's welfare.C) It covered up the differences between individual citizens.D) It failed to count in their difference in natural resources.49. What is an advantage of the Jones-Klenow method?A) It can accurately pinpoint a country's current economic problems.B) It can help to raise people's awareness of their economic well-being.C) It can diagnose the causes of a country's slowing pace of economic impr ovement.D) It can compare a country's economic conditions between different periods of time.50) What can we infer from the passage about American people's economic well-being?A) It is much better than that of their European counterparts.B) It has been on the decline ever since the turn of the century.C) It has not improved as much as reported by the Census Bureau.D) It has not been accurately assessed and reported since mid-2000s. Passage TwoQuestions 51 to 55 are based on the following passage.If you've ever started a sentence with,"If I were you..." or found yourself scratching yourhead at a colleague's agon y over a decision when the answer is crystal-clear, there's ascientific reason behind it. Our own decision-making abilities can become depleted over thecourse of the day causing indecision or poor choices, but choosing on behalf of someone elseis an enjoyable task that doesn't suffer the same pitfalls. The problem is "decision fatigue," a psychological phenomenon that takes a toll on thequality of your choices after a long day of decision making, sa ys Evan Polman, a leadingpsychologist.Physicians who have been on the job for several hours, for example, are more likely toprescribe antibiotics to patients when it's unwise to do so. "Presumably it's because it'ssimple and easy to write a prescription and con sider a patient case closed rather thaninvestigate further," Polman says.But decision fatigue goes away when you are making the decision for som eone else.When people imagine themselves as advisers and imagine their ow n choices as belonging tosomeone else, they feel less tired and rely less on d ecision shortcuts to make those choices."By taking upon the role of adviser rather than decision maker, one does not suffer theconsequences of decision fatigue," he says."It's as if there's something fun and liberatingabout making someone else's c hoice."Getting input from others not only offers a fresh perspective and thought pr ocess; it oftenalso includes riskier choices. While this sounds undesirable, it c an be quite good, says Polman."When people experience decision fatigue-when they are tired of making ch oices—theyhave a tendency to choose to go with the status quo (现状)," he says."But the status quocan be problematic, since a change in the course of acti on can sometimes be important andlead to a positive outcome."In order to achieve a successful outcome or reward, some level of risk is al most alwaysessential."People who are susceptible to decision fatigue will likely choose to do not hingover something," he says,"That's not to say that risk is always good, but it is related totaking action9w hereas decision fatigue assuredly leads to inaction and the possible chagrin(懊恼) of a decision maker who might otherwise prefer a new course but is unfo rtunatelyhindered."Just because you can make good choices for others doesn't mean you'll do th e same foryourself, Polman cautions."Research has found that women negotiate higher salaries forothers than the y do for themselves," he says, adding that people slip in and out of decision roles.51. What does the author say about people making decisions?A) They may become exhausted by making too many decisions for themselve s.B) They are more cautious in making decisions for others than for themselve s.C) They tend to make decisions the way they think advantageous to them.D) They show considerable differences in their decision-making abilities.52. What does the example about the physicians illustrate?A) Patients seldom receive due care towards the end of the day.B) Prescription of antibiotics can be harmful to patients' health.C) Decision fatigue may prevent people making wise decisions.D) Medical doctors are especially susceptible to decision fatigue.53. When do people feel less decision fatigue?A) When they take decision shortcuts.B) When they help others to make decisions.C) When they have major decisions to make.D) When they have advisers to turn to.54. What are people likely to do when decision fatigue sets in?A) They turn to physicians for advice.B) They tend to make risky decisions.C) They adopt a totally new perspective.D) They refrain from trying anything new.55. What does the passage say about taking some risk in decision making?A) It is vital for one to reach the goal desired.B) It is likely to entail serious consequences.C) It will enable people to be more creative.D) It will more often than not end in regret.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30minutes to translate a passage from Chinese intoEnglish.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.Did Sarah Josepha Hale write “Mary's Little Lamb,” the eternal nursery rhyme (儿歌) about a girl named Mary with a stubborn lamb? This is still dispute , but it’s clear that the woman __26__ for writing it was one of America's most fascinating __27 _. In honor of the poem's publication on May 24，1830，here’s more about the __28__ author's life.Hale wasn’t just a writer, she was also a __29__ social advocate, and she was particularly __30_ with an ideal New England, which she associated with abundant Thanksgiving meals that she claimed had “a deep moral influence.”she began a nationwide __31__ to have a national holiday declared that would bring families together whilecelebrating the __32__ festivals. In 1863, after 17 years of advocacy including letters to five presidents， Hale got it. President Abraham Lincoln, during the Civil War, issued a __33__ setting aside the last Thursday in November for the holiday.The true authorship of “Mary’s Little Lamb” is disputed.. According to New England Historical Society, Hale wrote only one part of the poem, but claimed authorship. Regardless of the author, it seems that the poem was __34__by a real event. When young Mary Sawyer was followed to school by a lamb in 1816, it caused some problems. A bystander named John Roulstone wrote a poem about the event, then, at some point, Hale herself seems to have helped write it. However, if a 1916 piece by her great-niece is to be trusted, Hale claimed for the __35__of her life that “Some other people pretended that someone else wrote the poem”.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 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 Sheet2.Grow Plants Without Water[A].Ever since humanity began to farm our own food, we've faced the unpredictable rain that is bothfriend and enemy. It comes and goes without much warning, and a field of lush(茂盛的) leafy greens one year can dry up and blow away the next. Food security and fortunes depend on sufficient rain, and nowhere more so than in Africa, where 96% of farmland depends on rain instead of the irrigation common in more developed places. It has consequences : South Africa's ongoing drought—the worst in three decades— will cost at least a quarter of its com crop this year. [B].Biologist Jill Farrant of the University of Cape Town in South Africa says that nature has plenty ofanswers for people who want to grow crops in places with unpredictable rainfall. She is hard at work finding a way to take traits from rare wild plants that adapt to extreme dry weather and use them in food crops. As the earth's climate changes and rainfall becomes even less predictable in some places, those answers will grow even more valuable."The type of farming I'm aiming for is literally so that people can survive as it's going to get more and more dry,"Farrant says.[C].Extreme conditions produce extremely tough plants. In the rusty red deserts of South Africa, steep-sided rocky hills called inselbergs rear up from the plains like the bones of the earth. The hills are remnants of an earlier geological era, scraped bare of most soil and exposed to the elements. Yet on these and similar formations in deserts around the world, a few fierce plants have adapted to endure under ever-changing conditions.[D].Farrant calls them resurrection plants (复苏植物) . During months without water under a harsh sun.They wither, shrink and contract until they look like a pile of dead gray leaves. But rainfall can revive them in a matter of hours. Her time-lapse(间歇性拍摄的) videos of the revivals look like someone playing a tape of the plant's death in reverse.[E].The big difference between"drought-tolerant" plants and these tough plants: metabolism. Manydifferent kinds of plants have developed tactics to weather dry spells. Some plants store reserves of water to see them through a drought ; others send roots deep down to subsurface water supplies. But once these plants use up their stored reserve or tap out the underground supply, they cease growing and start to die. They may be able to handle a drought of some length, and many people use the term "drought tolerant" to describe such plants, but they never actually stop needing to consume water, so Farrant prefers to call them drought resistant.[F].Resurrection plants, defined as those capable of recovering from holding less than 0.1 grams of waterper gram of dry mass, are different. They lack water-storing structures, and their existence on rock faces prevents them from tapping groundwater, so they have instead developed the ability to change their metabolism .When they detect an extended dry period, they divert their metabolisms, producing sugars and certain stress-associated proteins and other materials in their tissues. As the plant dries, these resources take on first the properties of honey, then rubber, and finally enter a glass-like state that is"the most stable state that the plant can maintain,"Farrant says. That slows the plant's metabolism and protects its dried-out tissues. The plants also change shape, shrinking to minimize the surface area through which their remaining water might evaporate. They can recover from months and years without water, depending on the species.[G].What else can do this dry-out-and-revive trick? Seeds-almost all of them. At the start of her career,Farrant studied . recalcitrant seeds (执拗性种子) ," such as avocados, coffee and lychee. While tasty, such seeds are delicate--they cannot bud and grow if they dry out (as you may know if you've ever tried to grow a tree from an avocado pit). In the seed world, that makes them rare, because most seeds from flowering plants are quite robust. Most seeds can wait out the dry, unwelcoming seasons until conditions are right and they sprout(发芽). Yet once they start growing, such plants seem not to retain the ability to hit the pause button on metabolism in their stems or leaves.[H].After completing her Ph. D. on seeds, Farrant began investigating whether it might be possible toisolate the properties that make most seeds so resilient (迅速恢复活力的) and transfer them to other plant tissues. What Farrant and others have found over the past two decades is that there are many genes involved in resurrection plants' response to dryness. Many of them are the same that regulate how seeds become dryness-tolerant while still attached to their parent plants. Now they are trying to figure out what molecular signaling processes activate those seed-building genes in resurrection plants—and how to reproduce them in crops."Most genes are regulated by a master set of genes,"Farrant says."We're looking at gene promoters and what would be their master switch." [I].Once Farrant and her colleagues feel they have a better sense of which switches to throw, they willhave to find the best way to do so in useful crops."I'm trying three methods of breeding,"Farrant says : conventional, genetic modification arid gene editing. She says she is aware that plenty of people do not want to eat genetically modified crops, but she is pushing ahead with every available tool until one works. Farmers and consumers alike can choose whether or not to use whichever version prevails :"I'm giving people an option. "[J].Farrant and others in the resurrection business got together last year to discuss the best species of resurrection plant to use as a lab model. Just like medical researchers use rats to test ideas for human medical treatments, botanists use plants that are relatively easy to grow in a lab or greenhouse setting to test their ideas for related species. The Queensland rock violet is one of the best studied resurrection plants so far, with a draft genome(基因图谱) published last year by a Chinese team.Also last year, Farrant and colleagues published a detailed molecular study of another candidate, Xerophyta viscosa, a tough-as-nail south African plant with lily-like flowers, and she says that a genome is on the way. one or both of these models will help researchers test their ideas —so far mostly done in the lab— on test plots.[K].Understanding the basic science first is key. There are good reasons why crop plants do not use dryness defenses already. For instance, there's a high energy cost in switching from a regular metabolism to an almost-no-water metabolism. It will also be necessary to understand what sort of yield farmers might expect and to establish the plant's safety."The yield is never going to be high,"Farrant says, so these plants will be targeted not at Iowa farmers trying to squeeze more cashout of high-yield fields, but subsistence farmers who need help to survive a drought like the present one in South Africa."My vision is for the subsistence farmer,"Farrant says."I'm targeting crops that are of African value. ".36. There are a couple of plants tough and adaptable enough to survive on bare rocky hills and in deserts.37. Farrant is trying to isolate genes in resurrection plants and reproduce them in crops.38. Farmers in South Africa are more at the mercy of nature, especially inconsistent rainfall.39. Resurrection crops are most likely to be the choice of subsistence farmers.40.Even though many plants have developed various tactics to cope with dry weather, they cannotsurvive a prolonged drought.41. Despite consumer resistance, researchers are pushing ahead with genetic modification of crops.42. Most seeds can pull through dry spells and begin growing when conditions are ripe, but once thisprocess starts, it cannot be held back.43. Farrant is working hard to cultivate food crops that call survive extreme dryness by studying thetraits of rare wild plants.44. By adjusting their metabolism, resurrection plants can recover from an extended period of drought.45. Resurrection plants can come back to life in a short time after a rainfall.Section CDirections：There are 2 passages 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). Youshould 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.Human memory is notoriously unreliable. Even people with the sharpest facial-recognitionskills can only remember so much.It's tough to quantify how good a person is at remembering. No one really knows how manydifferent faces someone can recall, for example, but various estimates tend to hover in thethousands-based on the number of acquaintances a person might have.Machines aren't limited this way, Give the right computer a massive database of faces, and itcan process what it sees-then recognize a face it's told to find-with remarkable speed and precision.This skill is what supports the enormous promise of facial-recognition software in the 2lst century.It's also what makes contemporary surveillance systems so scary.The thing is, machines still have limitations when it comes to facial recognition. And scientists are only just beginning to understand what those constraints are. To begin to figure out how computers are struggling, researchers at the University of Washington created a massive database of faces- they call it MegaFace- and tested a variety of facial-recognition algorithms (算法) as they scaled up in complexity. The idea was to test the machines on a database that included up to 1 million different images of nearly 700,000 different people-and not just a large database featuring a relatively small number of different faces, more consistent with what's been used in other research.As the databases grew, machine accuracy dipped across the board. Algorithms that were right 95% of the time when they were dealing with a 13, 000-image database, for example, were accurate about 70% of the time when confronted with 1 million images. That's still pretty good, says one of the researchers, Ira Kemelmacher-Shlizerman."Much better than we expected, "she said.Machines also had difficulty adjusting for people who look a lot alike-either doppelgangers(长相极相似的人),whom the machine would have trouble identifying as two separate people, or the same person who appeared in different photos at different ages or in different lighting, whom themachine would incorrectly view as separate people."Once we scale up, algorithms must be sensitive to tiny changes in identities and at the same time invariant to lighting, pose, age, "Kemelmacher-Shlizerman said.The trouble is, for many of the researchers who'd like to design systems to address these challenges, massive datasets for experimentation just don't exist--at least, not in formats that are accessible to academic researchers.Training sets like the ones Google and Facebook have are private. There are no public databases that contain millions of faces. MegaFace's creators say it's the largest publicly available facial-recognition dataset out there.“An ultimate face recognition algorithm should perform with billions of people in a dataset, ”the researchers wrote.46. Compared with human memory, machines can .A)identify human faces more efficientlyC) store an unlimited number of human facesB) tell a friend from a mere acquaintanceD) perceive images invisible to the human eye47. Why did researchers create MegaFace?A) To enlarge the volume of the facial-recognition databaseB) To increase the variety of facial-recognition softwareC)To understand computers' problems with facial recognitionD) To reduce the complexity of facial-recognition algorithms48.What does the passage say about machine accuracy?A)It falls short of researchers' expectations.C) It varies greatly with different algorithms.B) It improves with added computing power.D) It decreases as the database size increases.49. What is said to be a shortcoming of facial-recognition machines?A) They cannot easily tell apart people with near-identical appearances.B) They have difficulty identifying changes in facial expressionsC) They are not sensitive to minute changes in people's moodD) They have problems distinguishing people of the same age50. What is the difficulty confronting researchers of facial-recognition machines?A)No computer is yet able to handle huge datasets of human facesB) There do not exist public databases with sufficient face samplerC)There are no appropriate algorithms to process the face samplesD) They have trouble converting face datasets into the right format.Passage TwoQuestions 51 to 55 are based on the following passage.Therere currently 21.5 million students in America, and many will be funding their college on borrowed money. Given that there's now over $1.3 trillion in student loans on the books, it's pretty clear that many students are far from sensible. The average student's debt upon graduation now approaches $40, 000, and as college becomes ever more expensive, calls to make it "free" are multiplying. Even Hillary Clinton says that when it comes to college,"Costs won't be a barrier."But the only way college could be free is if the faculty and staff donated their time, the buildings required no maintenance, and campuses required no utilities. As long as it's impossible to produce something from nothing costs are absolutely a barrier.The actual question we debate is who should pay for people to go to college. If taxpayers are to bear the cost of forgiving student loans, shouldn't they have a say in how their money is used?At least taxpayers should be able to decide what students will study on the public dime. If we're going to force taxpayers to foot the bill for college degrees, students should only study those subjects that're of greatest benefit to taxpayers. After all, students making their own choices in this respect is what caused the problem in the first place.We simply don't need more poetry, gender studies, or sociology majors. How do we know which subjects benefit society? Easy.Average starting salaries give a clear indication of what type of training society needs its new workers to have. Certainly, there're benefits to a college major beyond the job a student can perform. But if we're talking about the benefits to society, the only thing that matters is what the major enables the student to produce for society. And the value of what the student can produce is reflected in the wage employers are willing to pay the student to produce it.A low wage for elementary school teachers, however, doesn't mean elementary education isn’t important. It simply means there're too many elementary school teachers already.Meanwhile, there're few who're willing and able to perform jobs requiring a petroleum engineering major, so the value of one more of those people is very highSo we can have taxpayers pick up students' tuition in exchange for dictating what those students will study. Or we can allow students both to choose their majors and pay for their education themselves. But in the end ,one of two things is true:Either a college major is worth its cost or it isn't. If yes, taxpayer financing isn't needed If not taxpayer financing isn't desirable. Either way, taxpayers have no business paying for students' college education.51. What does the author think of college students funding their education through loans?A)They only expect to get huge returns.C) They benefit at taxpayers expense.B)They are acting in an irrational way.D) They will regret doing so someday.A) impracticalB)unsustainableC)a goal to strive forD) a way to social equality53. What should students do if taxpayers are to bear their college costs?A) Work even harder to repay society.B) Choose their subjects more carefully.C) Choose majors that will serve society's practical need.D) Allow taxpayers to participate in college administration.54. What does the author say about the value of a student's college education?A) It is underestimated by profit-seeking employers.C) It is well reflected in their average starting salary.B) It is to be proved by what they can do on the job.D) It is embodied in how they remove social barriers.55. What message does the author want to convey in the passage?A)Students should think care fully whether to go to collegeB) Taxpayers should only finance the most gifted students.C)The worth of a college education is open to debate.D) College students should fund their own education..Part I Translation(30minutes)Directions：For this part, you are allowed 30 minutes to transate a passage from Chinese into Engtish.

You are required to write at least 150 words but no more than 200 words.【参考范文】Whether to Attend a Vocational College or a UniversityIt’s an undisputable truth that virtually all high school graduates will encounter the choices between a vocational college and a university. And when it comes to this question, students’ ideas are not cut from the same cloth. In point of which to choose and what to be taken into consideration, my advices are as follow.In the first place, we should be conscious of the fact that both of the two choices have its own superiorities. For instance, a vocational college specializes in cultivating human resources with practical capabilities; while a university serves as the cradle of academic researchers in differentfields. Then it does follow that high school graduates should have a clear picture of themselves. That is to say, they should know their merits and demerits and their choices must give play to their strengths whilst circumvent weaknesses. In addition, interest is the best teacher and it’s also the premise of learning on one’s own initiative. Thus interest must be taken into account because it can not only decide how far one can reach academically and professionally but also how happy and fulfilled one will be.In brief, all above just goes to show that there really is no one-size-fits-all answer for the question.

TranslationPart I Writing1．For this part, you are allowed 30 minutes to write an essay on the importance of building trust between teachers and students. You can cite examples to illustrate your views. You should write at least 150 words but no more than 200 words.正确答案：The Importance of Building Trust Between Teachers and Students There is no denying that trust is an indispensable part of pleasant relationship between teachers and students. A renowned saying goes that trust is a priceless treasure and plays an important role in maintaining social harmony. If a student distrusts his teacher, he is very likely to lose interest in the subject. Therefore, it is imperative to build trust between teachers and students. First of all, with mutual trust, students’motivation to learn will be greatly enhanced. When students have faith in the teacher and what he or she imparts, they will put all their energies into study to acquire knowledge and pursue excellence. Undoubtedly, this will surely benefit students themselves. Second, teachers will be actively encouraged if students trust them, for students’ credibility will give them a sense of achievement in teaching career. Besides, teachers will care more about students’studies and development, which is a win-win result for both of them. Tolstoy, a Russian writer, once said, “To do the real bosom friend, you have to trust each other. “ Hence, from what’s been discussed above, we can see that trust is a must. Only by building mutual trust can teachers and students become close friends and have a sound relationship.解析：这是一篇议论文写作。

2018年6月英语六级答案WritingFor this part, you are allowed 30 minutes to write an essay on the importance of building trust between businesses and consumers/teachers and students/employers and employees. You can cite examples to illustrate your views. 150-200 words.ModelIt is a truth universally acknowledged that the trust between businesses and consumers plays a key role in boosting the prosperity of our commercialized society. When the trust is built, it gives tremendous freedom to the consumers and the companies they choose; but when the trust is lost, it can cost a company’s life and is impossible to recover.For instance, Sanlu Milk Powder company used to be one of biggest dairy companies in China, and a huge number of Chinese citizens drank it everyday, hoping to make their bodies stronger and healthier. However, ten years ago, the news that there was poisonous ingredient in it and some infants were fatally sick because they drank it was exposed to the public. This scandal went viral and devastated the image of Sanlu in a few months. Another case is Xiaomi, which used to sell cheap digital products. A lot of people did not trust it because the price was very low. However, its dedication to producing cheap products with high quality has gradually built trust between consumers and this brand, and, not long ago, its goodwill and reputation helped it go public and earn a huge amount of money.In order to earn the trust of consumers, businesses should always keep their promises to them. Meanwhile, it is about time that some consumers who like taking advantages of businesses changed this habit and helped to protect the benefit of these companies.共享单车：Bikes once were the most important means of transportation in the cities and villages in China which used to be called the Kingdom of Bikes. At present, with traffic congestion and air pollution becoming increasingly severe, riding bikes are popular again. In the past several years, Chinese entrepreneurs have combined the mobile Internet technology with traditional bikes, inventing a brand new commercial mode called shared bikes. The advent of shared bikes makes riding more convenient. People can ride shared bikes anytime as they wish only when equipped with a smart phone. To encourage people to ride bikes when they go out, cycle tracks have been built in many cities. Now, Chinese people in increasing numbers like building their bodies through riding bikes as well.高铁：At present, China has the largest and fastest high-speed railway network in the world. The running velocity of high-speed rail will keep climbing and more cities will built their own high-speed rail stations. The high-speed rail greatly shortens people’s travel time. Compared with airplanes, high-speed trains have an outstanding merit which is punctuality because the operation of high-speed rail is basically not influenced by not only weather conditions but also traffic control. The high-speed rail has tremendously changed Chinese people’s life styles. At present, it has been the most preferred transportation for many people when they are on business trips. People in increasing amount also go traveling by high-speed rail on holidays. There are also many young people, who choose to work in one city and live in a nearby city, commuting between two different cities by high-speed rail everyday.阅读：第一套：选词填空文章来源：《Domestic robots are a not too distant reality》文章概要：文章简单介绍了科技大咖--Elon Musk为人类所作出的贡献，其中之一便是机器人在生活中的使用。
