Part ⅢReading Comprehension ( 40 minutes )Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.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 Sheet 2.How a Poor, Abandoned Parisian Boy Became a Top ChefA) When you drop a piece of food on the floor, is it really OK to eat if you pick it up within five seconds? An urban food myth contends that if food spends just a few seconds on the floor, dirt and germs won’t have much of a chance to contaminate it. Research in my lab has focused on how food becomes contaminated, and we’ve done some work on this particular piece of wisdom.B) While the “five-second rule” might not seem like the most pressing issue for food scientists to get to the bottom of, it’s still worth investigating food myths like this one because they shape our beliefs about when food is safe to eat.C) So is five seconds on the floor the critical threshold（门槛）that separates a piece of eatable food from a case of food poisoning? It’s a bit more complicated than that. It depends on just how many bacteria can make it from floor to food in a few seconds and just how dirty the floor is.D) Wondering if food is still OK to eat after it’s dropped on the floor is a pretty common experience. And it’s probably not a new one either. A well-known, but inaccurate, story about Julia Child may have contributed to this food myth. Some viewers of her cooking show, The French Chef, insist they saw Child drop lamb on the floor and pick it up, with the advice that if they were alone in the kitchen, their guests would never know.E) In fact it was a potato pancake, and it fell on the stovetop, not on the floor. Child put it back in the pan, saying, “But you can always pick it up and if you’re alone in the kitchen, who’s going to see it?” But the misremembered story persists. It’s harder to pin down the origins of the oft-quoted five-second rule, but a 2003 study reported that 70% of women and 56% of men surveyed were familiar with the five-second rule and that women were more likely than men to eat food that had dropped on the floor.F) So what does science tell us about what a few moments on the floor means for the safety of your food? The earliest research report on the five-second rule is attributed to Jillian Clarke, a high school student participating in a research project at the University of Illinois. Clarke and her colleagues introduced bacteria to floor tiles（瓷砖）and then placed cookies on the tiles for varying times. They reported bacteria were transferred from the tiles to the cookies within five seconds, but didn’t report the specific amount of bacteria that made it from the tiles to the food.G) But how many bacteria actually transfer in five seconds? In 2007, my lab at Clemson University published a study in the Journal of Applied Microbiology. We wanted to know if the length of time food is in contact with a contaminated surface affected the rate of transfer of bacteria to the food. To find out, we introduced bacteria to squares of tile, carpet or wood. Five minutes after that, we placed either bacon or bread on the surface for 5,30 or 60 seconds, and then measured the number of bacteria transferred to the food. We repeated this exact procedure after the bacteria had been on the surface for 2,4,8 and 24 hours.H) We found that the number of bacteria transferred to either kind of food didn’t depend much on how long the food was in contact with the contaminated surface—whether for a few seconds or for a whole minute. The overall number of bacteria on the surface mattered more, and this decreased over time after the initial introduction. It looks like what’s at issue is less how long your food stays on the floor and much more how contaminated with bacteria that patch of floor happens to be.I) We also found that the kind of surface made a difference as well. Carpets, for instance, seem to be slightly better places to drop your food than wood or tile. When a carpet was contaminated, less than 1% of the bacteria were transferred. But when the food was in contact with tile or wood, 45-70% of bacteria were.J) Last year, a study from Aston University in the UK used nearly identical parameters（参数）to our study and found similar results. They also reported that 87% of people asked either would eat or had eaten food fallen on the floor.K) Should you eat food fallen on the floor then? From a food safety standpoint, if you have millions or more bacteria on a surface, 0.1% is still enough to make you sick. Also, certain types of bacteria are extremely harmful, and it takes only a small number to make you sick. For example, 10 bacteria or less of an especially deadly strain of bacteria can cause severe illness and death in people with compromised immune systems. But the chance of these bacteria being on most surfaces is very low.L）And it’s not just dropping food on the floor that can lead to bacterial contamination. Bacteria are carried by various “media”, which can include raw food, moist surfaces where bacteria have been left, our hands or skin and from coughing or sneezing（打喷嚏）. Hands, foods and utensils（器皿）can carry individual bacteria living in communities contained within a protective film. These microscopic layers of deposits containing bacteria are known as biofilms and they are found on most surfaces and objects. Biofilm communities can harbor bacteria longer and are very difficult to clean. Becteria in these communities also have an enhanced resistance to sanitizers（清洁剂）and antibiotics compared to bacteria living on their own.M）So the next time you consider eating fallen food, the odds are in your favor that you can eat it without getting sick. But in the rare chance that there is a micro-organism that there is a micro-organism that can make you sick on the exact spot where the food dropped, you can be fairly sure that the bug is on the food you are about to put in your mouth.N）Research or common sense tells us that the best thing to do is keep your hands, utensils and other surfaces clean.36. A research project found bacteria made their way to the food on the floor in five seconds.37. Whether food is contaminated depends much on the number of bacteria that get onto it.38. Food contamination may result from various factors other than food dropping on the floor.39. Males are less likely than females to eat food that may have been contaminated.40. The author’s research centers around how food gets contaminated.41. Keeping everything clean is the best way to stay healthy.42. Chances are you will not fall sick because of eating food picked up from the floor.43. For a long time people have had the experience of deciding whether or not to eat food picked up from the floor.44. Some strains of bacteria are so harmful that a tiny few can have deadly consequences.45. Researchers found how many bacteria got onto the food did not have much to do with how long the food stayed on a contaminated floor.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.The latest in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect.According to a newly published study, cats seem to be able to predict the location of hiding prey（猎物）using both their ears and an inborn（天生的）understanding of how the physical world works.In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a team member shook. Some containers rattled（发出响声）；others did not. When the container was tipped over, sometimes an object fell out and sometimes it didn’t. It turns out that the cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected. “Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects,” lead researcher Saho Takagi says in a press release. The researchers conclude that cats’ hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing.Scientists have explored this idea with other endearing creatures: babies. Like cats, babies appear to engage in what’s called “preferential looking”—looking longer at things that are interesting or unusual than things they perceive as normal. When babies’ expectations are violated in experiments like the ones performed with the cats, they react much like their animal friends. Psychologists have shown that babies apparently expect their world to comply with the laws of physics and cause and effect as early as two months of age.Does the study mean that cats will soon grasp the ins and outs of cause and effect? Maybe. Okay, so cats may not be the next physics faculty members at America’s most important research universities. But by demonstrating their common sense, they’ve shown that the divide between cats and humans may not be that great after all.46.What do we learn from a newly published study about cats?A) They can be trained to understand the physical world.B) They know what kind of prey might be easier to hunt.C) They have a natural ability to locate animals they hunt.D) They are capable of telling which way their prey flees.47. What may account for the cats’ response to the noise from the containers?A) Their inborn sensitivity to noise.B) Their unusual sense of direction.C) Their special ability to perceive.D) Their mastery of cause and effect.48. What is characteristic of the way cats hunt, according to the Japanese researchers?A) They depend on their instincts. C) They wait some time before attack.B)They rely mainly on their hearing. D) They use both their ears and eyes.49. In what way do babies behave like cats?A) They focus on what appears odd.B) They view the world as normal.C) They do what they prefer to do.D) They are curious about everything.50. What can we conclude about cats from the passage?A) They have higher intelligence than many other animals.B) They interact withe the physical world much like humans.C) They display extraordinarily high intelligence in hunting.D) They can aid physics professors in their research work.Passage TwoQuestions 51 to 55 are based on the following passage.Imagine you enter a car with no steering wheel, no brake or accelerator padals（踏板）. Under a voice-activated command, you say an address. “The fastest route will take us 15.3 minutes. Should I take it?” You say “yes” and you are on your way. The car responds and starts moving all by itself. All you have to do is sit back and relax.How weird would it be if, one day in the future, everyone had such a car? No crazy driving, no insults, no cutting in; traffic laws would be respected and driving much safer. On the other hand, imagine the cost savings for local police enforcement and town budgets without all those speeding and parking tickets.A new technology has the potential to change modern society in radical ways. There’s no question that self-driving vehicles could be an enormous benefit. The potential for safer cars means accident statistics would drop: some 94% of road accidents in the U.S. involve human error. Older drivers and visually-or physically-impaired people would gain a new level of freedom. Maintaining safe speeds and being electric, self-driving cars would drastically reduce pollution levels and dependency on non-renewable fuels. Roads would be quieter, people safer.But we must also consider the impact of the new technology on those who now depend on driving for their livelihoods. According to the U.S. Department of Labor, in May 2015 there were 505,560 registered school bus drivers. The American Trucking Association lists approximately 3.5 million professional truck drivers in the U.S.The companies developing self-driving vehicles should be partnering with state and federal authorities to offer retraining for this massive workforce, many of whom will be displaced by the new technology. This is similar to what’s happening in the coal and oil industries a situation that fuels much of the current political discontent in this country. New technologies will, and should, be developed. This is how society moves forward. However, progress can’t be one-sided. It is necessary for the companies and state agencies involved to consider the ethical consequences of these potential changes to build a better future for all.51.What would be the impact of the extensive use of driverless cars?A) People would be driving in a more civilized way.B) It would save local governments a lot of money.C) More policemen would be patrolling the streets.D) Traffic regulations would be a thing of the past.52. How would the elderly and the disabled benefit from driverless cars?A) They could enjoy greater mobility.B) They would suffer no road accidents.C) They would have no trouble driving.D) They could go anywhere they want.53. What would be the negative impact of driverless cars?A) The conflict between labor and management would intensify.B) The gap between various sectors of society would be widened.C) Professional drivers would have a hard time adapting to new road conditions.D) Numerous professional drivers would have to find new ways of earning a living.54. What is the result of the introduction of new technologies in energy industries?A) Political dissatisfaction.B) Retraining of employees.C) Fossil fuel conservation.D) Business restructuring.55. What does the author suggest businesses and the government do?A) Keep pace with technological developments.B) Make new technologies affordable to everyone.C) Enable everyone to benefit from new technologies.D) Popularize the use of new technologies and devices.Part ⅣTranslation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

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.

2018年12月大学英语六级真题解析(仔细阅读卷二)
2018年12月份大学英语六级仔细阅读译文及详细解析（卷二）Section CPassage One全文翻译及命题分析也许是时候让农场主们歇歇脚了，因为机器人正被用来监测庄稼生长、拔除杂草，甚至放牧。
商业种植面积及其广袤，需要数千工时来耕作。
澳大利亚最偏远的苏坡杰克·唐斯（Suplejack Downs）牛场就是一个典型的例子。
它位于北部地区，绵延4000平方公里，距离最近的主要城市艾丽丝泉（Alice Springs）逾13个小时车程。
这些大规模农场极度偏远，往往无人照料，每年只能监测一两次，这意味着如果牲畜生病或需要援助，农场主可能需要很长时间才能发现。
然而，机器人正前来救援。
机器人目前正在威尔士进行为期两年的试验，该试验将训练“农场机器人”放牧，监测牲畜的健康，并确保有足够的牧场供它们放牧。
这些机器人配备了许多传感器来识别环境、牛群以及食物的状况，使用热传感器和视觉传感器来探测体温的变化。
悉尼大学的萨拉·苏卡黎(Salah Sukarieh)将在新南威尔士州中部的几个农场进行试验，他说：“你还可以用颜色、质地和形状传感器检测地面上的牧草质量。
”在试验期间，将对机器人的算法和技术性细节进行微调，使其更适合生病的牲畜，并确保它能够安全地绕过树木、淤泥、沼泽和丘陵等潜在障碍区。
苏卡黎说:“我们希望改善牲畜的健康品质，并让农场主更容易维护牲畜在广阔的草场上信步由缰的壮观景象。
”机器人并不局限于放牧和监控牲畜，他们还被用来统计单果数量，检查农作物，甚至拔除杂草。
许多机器人配备有高科技传感器和复杂的学习算法，以避免它们在与人类并肩工作时伤害人类。
机器人还知晓最高效、最安全的通行方式，使工程师和农场主能够分析和更好地优化机器人的属性和任务，并提供现场直播，实时反馈农场上正在发生的事情。
当然，农业工人担心其岗位被取代。
然而，由于劳动力空缺的不断加剧，大规模生产难以维持，正是农场主们在力推技术进步。

Mark your answers on the ANSWER SHEET. (40 points)Text 1The measures taken by countries around the world in recent years to cut greenhouse gas emissions have fallen well short of what is needed to avoid dangerous climate change, according to research led by the International Energy Agency. The study indicates that global emissions have risen 65% since 1990, but estimates that a decrease of 51% by 2030 is needed to limit warming to 2°C above pre-industrial levels. The research also found that the number of people without electricity access in the developing world fell to 1billion for the first time last year, but that population growth could enable this to rise again. It concluded that countries must increase their use of renewable energy to meet climate targets.6. What does the research conducted by the International Energy Agency find?A. Countries worldwide have successfully reduced greenhouse gas emissions.B. Worldwide measures on greenhouse gas emissions have fallen shortof the target.C. Global emissions have declined 65% since 1990.D. The earth is unlikely to warm 2°C by 2030.7. What does the International Energy Agency suggest countries to do to meet climate targets?A. Cut greenhouse gas emissions by 65%.B. Limit warming to 2°C above industrial levels.C. Increase the use of renewable energy.D. Reduce population growth in developing countries.Text 2American drivers who want to save on their gas bills should take a good look at the country's pump prices. Although they are cheap compared with many other countries ― around half the cost in much of Europe ― they still vary widely across America, which is costing some drivers thousands ofdollars each year. The differences can be explained by a combination of tax rates, transport costs and government environmental compliance regulations. Some of the key factors affecting the prices are outlined below.- Tax rates: Each state has different rates of tax on gasoline. Federal taxes account for 18.4 cents per gallon.- Transport costs: Remote areas often have higher fuel prices due to the high cost of transporting it there.- Environmental regulations: Federal regulations require at least 10% ethanol (乙醇) to be added to the gasoline supply. However, the target is harder to meet in some regions due to a lack of refineries and pipelines.8. Why is gasoline cheaper in America than in Europe?A. Gasoline is taxed less in America.B. Transport costs are lower in America.C. Environmental regulations are stricter in America.D. There are more refineries and pipelines in America.9. What does the underlined word "outlined" in the second paragraph mean?A. DrawnB. DiscussedC. AnalyzedD.

She made her screen debut in 1972's "The Godfather" when she was an infant, playing thebaby being christened (给...施洗礼) in the climatic Baptism (施洗礼) Massacre (大屠杀) sequence (片段). As a girl she didn't want to become an actress, citing an aversion (厌恶) to the trappings (陷阱) of the movie business. There was also the fact that her parents divorced when she was 3 years old (leading to her mother's going off to live in France and Sofia's living with her father in northern California).She studied Fine Art at the prestigious California Institute of Arts in Los Angeles, preferring painting to film-making, but also making an experimental short, "Bed Demon," in her spare time. This attracted the attention of George Lucas, who hired her to work on the final chapter of "Star Wars," "Return of the Jedi." During the production of the film, she met Spike Jonze, a director who shared her love of fashion and pop music. They were married at the tender age of 27, but soon separated because, some say, her fame eclipsed (使黯然失色) his.10. When did Sofia Coppola appear in "The Godfather"?A. In 1971.B.

[A] The busy streets in Paris were uneven and caked in thick mud, but there was always a breathtaking sight to see in the shop windows of Patisserie de la Rue de la Paix. By 1814, people crowded outside the bakery, straining for a glimpse of the latest sweet food created by the young chef who worked inside.[B] His name was Marie-Antoine Careme, and he had appeared, one day, almost out of nowhere. But in his short lifetime, which ended exactly 181 years ago today, he would forever revolutionize French gourmet food (美食) write best-selling cook books and think up magical dishes for royals and other important people.[C] Careme’s childhood was one part tragedy, equal part mystery. Born the 16th child to poor parents in Paris in either 1783 or 1784, a young Careme was suddenly abandoned at the height of the French Revolution. At 8 years old, he worked as a kitchen boy for a restaurant in Paris in exchange for room and board. By age 15, he had become an apprentice (学徒) to Sylvain Bailly, a well-known dessert chef with a successful bakery in one of Paris’s most fashionable neighborhoods.[D] Careme was quick at learning in the kitchen. Bailly encouraged his young apprentice to learn to read and write. Careme would often spend his free afternoons at the nearby National Library reading books on art and architecture. In the back room of the little bakery, his interest in design and his baking talent combined to work wonders he shaped delicious masterpieces out of flour, butter and sugar.[E] In his teenage years, Careme fashioned eatable copies of the late 18th century’s most famous buildings---cookies in the shape of ruins of ancient Athens and pies in the shape of ancient Chinese palaces and temples. Sylvain Bailly, his master, displayed these luxuriant creations---often as large as 4 feet tall---in his bakery windows.[F]Careme creations soon captured the discriminating eye of a French diplomat,Charles Maurice de Talleyrand- Perigord. Around 1804, Talleyrand challenged Careme to produce a full menu for his Personal castle, instating e young baker to use local season fruits and vegetables and to avoid repeating main dishes over the course of an entire year. The experiment was a grand success and Talleyrand’s association with French nobility would prove a profitable connection for Careme.[G] French Emperor Napoleon Bonaparte was known to be unimpressed by the declining taste of early 18th century cooking, but under pressure to entertain Paris’s high society, he too called Careme to his kitchen at Tuileries Palace. In 1810, Careme designed the extraordinary cake for the wedding of Napoleon and his second bride, Marie-luise of Austria. He became one of the first modern chefs to focus on the appearance of his table, not just the flavor of his dishes. “I want order and taste, A well-displayed meal is enhanced one hundred percent in my eyes,” he later wrote in one of his cook books[H] In 1816, Careme begin a culinary (烹饪的) journey which would forever mark his place as history’s first top chef. He voyaged to England to cook in the modern Great Kitchen of the prince regent (摄政王) George IV, and crossed continents to prepare grand banquets for the tables of Tsar Alexander I of Russia. Never afraid to talk up his own accomplishments, boastful Careme made a fortune as wealthy families with social ambitions invited him to their kitchens. Later, in his cook books, he would often include a sketch of himself, so that people on the street would be able to recognize---and admire---him.[I] Careme’s cooking displays became the symbol of fine French dining; they were plentiful, beautiful and imposing. Guests would fall silent in wonder as servants carried Careme’s fancy creations into the dining hall. For a banquet celebrating the Grand Duke Nicholas of Russia’s visit to George IV’s Brighton Pavilion on Jan. 18, 1817, the menu featured 120 different dishes, highlighting eight different soups 40 main courses, and 32 desserts[J] As he traveled through the homes of early 19th century nobility, Careme forged the new art of French gourmet food. Locked in hot kitchens, Careme created his four “mother sauces.” These sauces --- bechamel, veloute, espagnole and allemande---formed the central building blocks for many French main courses. He also perfected the soufflé---a baked egg dish, and introduced the standard chef’s uniform---the same double-breasted white coat and tall white hat still worn by many chefs today. The white clothing conveyed an image of cleanliness, according to Careme---and in his realm, appearance was everything.[K]Between meals, Careme wrote cook books that would be used in European kitchens for the next century. His manuals including The Royal Parisian Baker and the massive five-volume Art of French Cooking Series (1833-1847 completed after his death) first systematized many basic principles of cooking, complete with drawings and step-by-step directions. Long before television cooking shows, Careme walked readers through common kitchen tasks, instructing them to “try this for yourself, at home” as famous American Chef Jullia Child might do, many years later,[L] In the end, however, it was the kitchen that did Careme in. Decades of working over coal fires in tight, closed spaces with little fresh air (to ensure his dishes would not getcold) had fatally damaged his lungs. On Jan. 12, 1833, Careme died just before he turned 50.[M] But in his lifetime, Careme, ever confident, could see beyond his short domination in the kitchen. He wanted to “set the standard for beauty in classical and modern cooking, and prove to the distant future that the French chefs of the 19th century were the most famous in the world,” as he wrote in his papers36. Careme was among the first chefs who stressed both the appearance and flavor of dishes.37. Careme wanted to show to later generations that French chefs of his time were most outstanding in the world.38. Careme benefited greatly from serving a French diplomat and his connections.39. Careme learned his trade from a famous dessert chef in Paris.40. Careme’s creative works were exhibited in the shop windows by his master..41. Careme’s knowledge of art and architecture helped him create extraordinary desserts out of ordinary ingredient.42. Many people in Paris were eager to have a look at the latest sweet food made by Careme.43. Careme become extremely wealthy by cooking for rich and socially ambitious families.44. Careme’s writing dealt with fundamental cooking principles in a systematic way.45. Careme’s contribution to French cooking was revolutionary.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Roughly the size of a soda can sitting on a bookshelf, a relatively harmless gadget may be turning friends away from your home. The elephant in your living room is your Internet-connected security camera, a device people are increasingly using for peace of mind in their homes. But few stop to think about the effect these devices may have on house guests. Should you tell your friends, for instance, that they’re being recorded while you all watch the big game together?“It’s certainly new territory, especially as home security cameras become easier to install,” says Lizzie Post, president of the Emily Post Institute, America’s foremost manners advisors. “I think it will be very interesting to see what etiquette (礼仪) emerges in terms of whether you tell people you have a camera or not, and whether guests have a right to ask that it be turned off, if it's not a security issue.”Post wants to make clear that shes not talking about legal rights, but rather personalpreferences. She also wants to explain that there are no right or wrong answers regarding manners on this front yet, because the technology is just now becoming mainstream. Besides, the Emily Post Institute doesn’t dictate manners.When it comes to security cameras, Post says it’s a host’s responsibility to make sure guests feel comfortable within their home. “I’m always a fan of being open and honest.” For instance, if the host casually acknowledges that there is a camera in the room by telling a story about it, that may be enough to provide an opening for a guest to say if they are uncomfortable.However, if a contractor is working in your home, you don’t need to tell them that there are cameras watching. Then again, the air of accountability that the camera generates can also work in contractors’ favor, “If anything does go wrong while they’re in the house, they don’t want to be blamed for it,” she says. “In fact, the camera could be the thing that proves that they didn’t steal the $20, or knock the vase off the table.”46. For what reason may your friends feel reluctant to visit your home?A) The security camera installed may intrude into their privacy.B) They don’t want their photos to be circulated on the Internet.C) The security camera may turn out to be harmful to their health.D) They may not be willing to interact with your family members47. What does Lizzie Post say is new territory?A) The effect of manners adviceB) Cost of applying new technologies at homeC) The increasing use of home security devicesD) Etiquette around home security cameras.48. What is Lizzie Post mainly discussing with regard to the use of home security cameras?A) Legal rightsB) Moral issuesC) Likes and dislikes of individuals.D) The possible impact on manners.49. What is a host’s responsibility regarding security cameras, according to Lizzie Post?A) Making their guests feel at easeB) Indicating where they areC) Turning them off in time.D) Ensuring their guests’ privacy.50. In what way can the home security camera benefit visitors to your home?A) It can satisfy their curiosity.B) It can prove their innocence.C) It can help them learn new technology.D) It can make their visit more enjoyable.Passage TwoQuestions 51 to 55 are based on the following passage.PepsiCo is to spend billions of dollars to develop drinks and snacks and reformulate existing ones with lower sugar, salt and fat, as consumers demand healthier options and regulatory pressure intensifies amid an obesity epidemic（流行病）.The maker of Mountain Dew and Gatorade has been one of the earlier movers in the industry to offer products with reduced levels of unhealthy ingredients---PepsiCo claims a packet of its chips now contains less salt than a slice of white bread. However, its new 10-year plan makes clear it believes it still has a long way to go.Shifting eating habits, including a sharp drop in consumption of sparkling drinks, have forced radical change on the industry. But those shifts have yet to be reflected in record obesity levels, which stand at 36.5% overall in the US.Indra Nooyi, PepsiCo chairman, said the plan to make its products healthier was important for the company’s growth. But on the subject of obesity, she pointed out that consumers’ lifestyles have changed significantly, with many people being more sedentary（久坐不动的）not least because more time is spent in front of computers. She said PepsiCo’s contribution was to produce healthier snacks that still tasted good.Society has to change its habits, she added. “We can’t do much to alter sedentary lifestyles, but we can provide consumers with great-tasting products, low in salt, sugar and fat. In the past we had to have a taste trade-off. But were breaking that trade-off.”PepsiCo’s plan for its foods and drinks is based on guidelines from the World Health Organization, which last week backed using taxes on sparkling drinks to reduce sugar consumption. Initiatives also include efforts to reduce its environmental impact, water consumption and materials used in packaging by 2025.PepsiCo did not say exactly how much it planned to invest to reach its goals. However, Dr. Mehmood Khan, chief scientific officer, said the company had doubled research and development spending in the past five years and was “committed to sustaining investment”, adding that companies cannot cost-cut their way to increasing sales. PepsiCo’s research and development budget in 2015 was $754 million.51. Why is PepsiCo making a policy change?A) To win support from the federal government.B) To be more competitive in the global marketC) To satisfy the growing needs for healthy foodsD) To invest more wisely in the soft drink industry.52. What does PepsiCo think it will have to do in the future?A) Invest more to develop new snacksB) Reduce levels of obesity in the US.C) Change consumers’ eating habitsD) Keep on improving its products.53. Why does PepsiCo plan to alter its products, according to Indra Nooyi?A) To ensure the company’s future developmentB) To adapt to its customers’ changed tasteC) To help improve its consumers’ lifestylesD) To break the trade-off in its product design54. What does Indra Nooyi say about the obesity epidemic?A) It is mainly caused by overconsumption of snacksB) It results from high sugar and salt consumptionC) It is attributable to people’s changed lifestylesD) It has a lot to do with longer working hours55. What has PepsiCo been doing to achieve its obesity?A) Studying WHO’s guidelines.B) Increasing its research funding.C) Expanding its market overseasD) Cutting its production costs.Part ⅣTranslation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

**2018 年 12 月大学英语六级考试精编解析 (第三套)Part Ⅰ Writing范文How to Balance Academic Study and Extracurricular Activities Many students and their parents worry that spending time on extracurricular activities will hinder academic study which is understandable. But as for me, as long as we can strike a balance between them, proper participation in extracurricular activities will not only promote academic study, but also enhance our overall abilities. First of all, it’s advisable to schedule our schoolwork reasonably and finish it efficiently, for only in this way can we allocate extra time and energy to take part in extracurricular activities, which will have no negative impact on our academic study. Secondly, we should only spend time on activities we want to participate in, which will bring us enjoyment and relieve the academic pressure to some extent. Thirdly, we can also join clubs where we can meet like-minded people and improve our skills which are useful for our academic study. In a word, only by studying more efficiently and arranging extracurricular activities more rationally can we achieve a real balance between academic study and extracurricular activities.Part II Listening Comprehension说明：由于 2018 年 12 月六级考试全国共考了两套听力，本套真题听力 与前两套内容相同，只是选项顺序不同，因此在本套真题中不再重复出现。
