造价工程师建设工程造价案例分析第二套真题附答案建设工程造价案例分析真题解析【案例一】（2016真题改）（20分）某企业拟于某城市新建一个工业项目，该项目可行性研究相关基础数据如下：1.拟建项目占地面积30亩，建筑面积11000m2，其项目设计标准，规模与该企业2年前在另一城市的同类项目相同已建同类项目的单位建筑工程费用为1600元/m2，建筑工程的综合用工量为4.5工日/m2，综合工日单价为80元/工日，建筑工程费用中的材料费占比为50%，机械使用费占比为8%，考虑地区和交易时间差拟建项目的综合工日单价为100元/工日，材料费修正系数为1.1，机械使用费的修正数为1.05，人材机以外的其它费用修正系数为1.08。

根据市场询价，该拟建项目设备投资估算为2000万元，设备安装工程费用为设备投资的15%。

项目土地相关费用按20万元/亩计算，除土地外的工程建设其他费用为项目建安工程费用的15%，项目的基本预备费率为5%，不考虑价差预备费。

2.项目建设期1年，运营期10年，建设投资全部形成固定资产。

固定资产使用年限为10年，残值率为5%，直线法折旧。

3.项目运营期第1年投入自有资金200万元作为运营期的流动资金。

4.项目正常年份销售收入为1560万元（不含销项税额），增值税税率为17%，增值税附加税率为10%，项目正常年份年经营成本为400万元（不含可抵扣的进项税额30万）。

项目运营第1年产量为设计产量的85%，第2年及以后各年均达到设计产量，运营期第1年的销售收入，经营成本，增值税、可抵扣的进项税额和增值税附加均为正常年份的85%。

企业所得税率为25%。

问题：（计算结果保留两位小数）1.列式计算拟建项目的建设投资。

2.若该项目的建设投资为5500万元，建设投资来源为自有资金和贷款，贷款为3000万元，贷款年利率为7.2%（按月计息），约定的还款方式为运营期前5年等额还本，利息照付方式。

分期列式计算项目运营期第1年，第2年的总成本费用和净利润以及运营期第2年年末的项目累计盈余资金，（不考虑企业公积金，公益金提取及投资者股利分配）。

of their cats.The findings suggest that just as apparent personality can affect the personality of a child,the same is true for a cat and its owner.Owners defined as individuals with high levels of anxiety,fear,anger,depression and loneliness were more likely to have cats with behavioral issues.Such cats display more aggressive and anxious behavioral styles as well as more stress related sickness.They will also more likely to have an ongoing medical condition and be overweight.The research also found that mentally well-adjusted owners had come from happier and healthier cats.Researchers explained that many owners regard their pets as a family member and form close social bonds with them.(17)The majority of owners want to provide the best care for their pets and is therefore possible that pets could be affected by the way their owners interact with and manage them.The study highlights an important relationship between our personalities and the well-being of our pets.(18)Further research is needed to investigate the cause of nature of this relationship and look at how owners’personalities are directly influencing their pet’s behavior and well-being.It is possible that the well-being of pets is driven by the underlying nature of the owner not simply by their conscious decisions and behaviors.16.What do we learn from the new study by the University of Lincoln?17.What does the passage say most pet owners want to do?18.What does the passage say it’s still needed to understand the effects of owners’personalities on their pets?Passage Two(19)One 50-minute run can add seven hours to your life.This was a claim made by The Times last week.The claim was based on a new review of studies about the effects of running.The review concluded that an average runners live three years longer than non-runners and that running does more to extend life than any other form of exercise.But there’s more to running than its health benefits.(20)Research published in recent years have shown that running changes your brain and mind in some fascinating ways from increasing your brain function to regulating your emotions.However,the precise effects vary according to whether you engage in short fast running or long distance running.For example,in one study,researchers compared participants’ability to learn new words after several minutes of intense running,and after 40 minutes of gentle running,participants were able to learn 20 percent faster after the intense running and they showed a superior memory when tested again a week later.In another study,researchers asked volunteers to jog for 30 minutes and then showed them clips from a sad movie.Participants who usually struggled to handle negative emotions were more intensely affected by the sad clips just as you’d expect.But crucially,this was less so if they had completed the 30 minutes jog.(21)The researchers said moderate exercise appears to have helped those participants to be less vulnerable to the impact of the sad movie.19.What did the new review of studies claim?20.What is one effect that running has on people according to recent research?21.What did another study find about the participant after they had a 30 minutes jog?Passage ThreeWelcome to the tour of the Hill House.This house built in 1904 is one of the most well-known works of Charles Hill,the famous architect.It was designed and built for local entrepreneur and his family.Before starting the tour,let me giveyou a brief introduction about the design of this amazing building.(23)Prior to beginning his design,the architect spends sometime in the client’s old home,observing their life and studying their habits.This meant that he could design the house according to the needs of the family.(24)The client’s main desire was to have a home with unique design,so the architect was given complete freedom.The building style is radically different from what was the fashion of the period.At the time,most large homes were constructed of timber and brick.This one,however,is made of concrete,a novel construction material in those days.The interior of the house,including the fittings and furniture,was also designed by the same person.Most of the furniture you will see is original and in good condition.However,(25)both pieces in the children’s bedrooms are copies built to the designs of the architect.Fortunately,all the blueprints for both the building and its contents have been preserved,so we’ve been able to replace badly damaged furniture.Let’s begin our tour,starting from the rooms.22.What do we learn about the speaker?He is the guide of the tour.23.What dis the architect do before beginning his design?24.What did the architect’s client mainly want?25.What do we learn about the pieces of furniture in the children’s bedrooms?1.D)He did an unusual good deed2.C)Give some money to the waiter3.A)Whether or not to move to the state's mainland4.B)It costs too much

been changed as well.The changes in the way of transportation can be listed as follows.First of all,with the development of technology,the price of transportation is much cheaper than before.Moreover,compared with traditional ways of buying tickets,transportation applications and websites give passengers the opportunityto book tickets online without going outside to particular ticket offices.Besides,highspeed railways gradually replace the oldfashioned green trains,which can tremendously improve travelers’comfort during the journey and shorten the time spent on the way.From my perspective,the changes in the way of transportation mainly lie in the good respects.As one of the fortunate passengers who live in the age of internet and can get access to online service of transportation,I can*t help exclaiming:it is the best of times.六、翻译部分：春节前夕吃团圆饭是中国人的传统。

TheRialto Bridge is one of the four bridges spanning the Grand Canal.It is the oldest bridge across the canal , and w as the dividing line between the districts of SanMarco and San Polo. But on this day, there was a twist : it was filled with Venetians, nottourists.B)"People are cheering and holding their carts in the air," says Giovanni Giorgio, who helped organize the march with a grass-roots organization called Gener azione '90. The carts herefers to are small shopping carts —the symbol of a tr ue Venetian. "It started as a joke," hesays with a laugh."The idea was to put blades on the wheels! You know? Like Ben Hur.Preciselylike that, you just go around and run people down."C) Venice is one of the hottest tourist destinations in the world. But that's a p roblem. Up to90,000 tourists crowd its streets and canals every day — far outn umbering the 55,000 permanent residents. The tourist increase is one key re ason the city's population is downfrom 175,000 in the 1950s. The outnumb ered Venetians have been steadily fleeing. Andthose who stick around are tir ed of living in a place where they can't even get to the marketwithout swimming through a sea of picture-snapping tourists. Imagine,navigating through50, 000 people while on the way to school orto work.D)Laura Chigi, a grandmother at the march, says the local andnational gove rnments havefailed to do anything about the crowdsfor decades, because they're only interested intourism — the primary industry in Venice, worth more than $3 billion in 2015. "Venice is acash cow,"she says, "and everyone wants apiece."E) Just beyond St. Mark's Square, a cruise ship passes, one of hundreds every year thatappear overtheir medieval ( 中世纪的) surroundings. Their massive wake creates waves atthe bottom of the sea, weakening the foundations of the centuries-old buildings themselves. "Every time I see a cruise ship, I feel sad,"Chigi says."You see the mud itdrags; the destruction it leaves in its wake? That hurts the ancient wooden poles holding up the cityunderwater. One day we'll see Ve nice break down."F)For a time, UNESCO, the cultural wing of the United Nations, seemed to ag ree. Two yearsago, it put Italy on notice, saying the government was not prot. .专业知识分享 . .. WORD 格式整理 . .ecting Venice. UNESCOconsiders the entire city a World HeritageSite, a greathonor that means Venice, at thecultural level, belongs to all ofthe world's people. In 2014, UNESCO gave Italy two years tomanage Venice'sflourishing tourism or the city would be placed on another list —WorldHeritage InDanger, joining such sites as Aleppo and Palmyra, destroyed by thewar in Syria.G) Venice's deadline passed with barely a murmur ( 嘟哝) this summer, just as UNESCO wasmeeting in Istanbul. Onlyonerepresen tative , Jad Tabet from Lebanon, tried to raise the issue."For several years, the situation of heritage in Venice has beenworsening, and it hasnow reached a dramatic situation," Tabet told UNESCO."We have to act quickly — there isnot a moment towaste."H) But UNESCO didn't even hold a vote."It's been postponed until 2017," says Anna Somers,the founder andCEO of The Art Newspaper and the former head of Venice inPeril, a group devoted to restoring Venetian art. She says the main reason the U.N. culturalorganizationdidn't vote to declare Venice a World Heritage Site In Danger isbecause UNESCO hasbecome "intensely politicized. There would have been someback-roomnegotiations."I) Italy boasts more UNESCO World Heritage Sites than any othercountry in the world,granting it considerabl e power and influence within theorganization. The former head of theUNESCO World Heritage Centre, whichoversees heritage sites, is Francesco Bandarin, aVenetian who now serves asUNESCO's assistan t director -general for culture.J) Earlier this year, Italy signed an accor d with UNESCO to establish a taskforce of police artdetectives andarchaeologists ( 考古学家) to protec tcultural heritage from natural disastersand terror groups, suc h as ISIS. The accor d underlined Italy's globa l reputation as a goodstewar d of art and culture.K) But adding Venice to the UNESCOendangered list— which is dominated by sites indeveloping and conflict -riddencountries — would be an internationalembarrassment , andcould even hurtItaly'sprofitable tourism industry. TheItalian Culture Ministry says itis unaware of any government effortsto pressure UNESCO. As for the organization itself, it declined arequest for aninterview .L) The city's current mayor, Luigi Brugnaro, has ridiculed UNESCO andtold itto mind its ownbusiness, while continuing to support the cruiseship industry,which employs 5,000Veniceresidents.M) As for Venetians, they're beyond frustrated andhoping for a solution soo n."It's a nightmarefor me. Some situations are really difficultwith tourists around," says Giorgio ashe navigates around a swelling crowd at the Rialto Bridge."There are just so many of them.They never know where they are going, anddo not walk in an orderlymanner. Navigatingthe streets can beexhausting.". .专业知识分享 . .. WORD 格式整理 . .N) Then it hits him: This crowd isn't made up of tourists. They'reVenetians. Giorgio sayshe'snever experienced the Rialto Bridge this way in all his 22 yea rs."For once, we are the oneswho are blocking the traffic," he saysdelightedly."It feels unreal. It feels like we're someform of endangered species . It's justnice. The feeling is just pure." But, he worries, iftourism isn'tmanaged and his fellow locals continue to move to the mainland, his generationmight bethe last who can call themselves native Venetians.36. T he passing cruise ships will underminethe foundations of the ancient b uildingsinVenice.37. T he Italian government has just reached an agreement with UNESCO to take measures to protect its culturalheritage.38. The heritage situation in Venice has been deteriorating in the pastfew years.39. T he decrease in the number of permanent residents in Venice is mainly due to theincrease oftourists.40. I f tourism gets out of contro l , native Venetians may desert thecity altogether one day.41. UNESCO urged the Italian government to undertake its responsibilitytoprotect Venice.42. T he participants in the Venetian march used shopping cartsto show they were 100% localresidents.43. I gnoring UNESCO's warning, the mayor of Venice maintains his support ofthe city'stourism industry.44. O ne woman says that for decades the Italian government andlocal author ities have onlyfocused on the revenues from tourism.45. U NESCO has not yet decided to put Venice on the list of WorldHeritage Si tes In Danger.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 cho ices marked A), B), C) andD). You should decide on the bestchoice and mark the corresponding letter on Answer Sheet2 with asingle line through the cen tre.Passage OneQuestions 46 and 50 are based on the following passage .Living in an urban area with green spaces has a long- lasting positive impac t on people's mental well-being, a study has suggested. UK researchers found moving to a green spacehad a sustained positive effect, unlike pay rises or promotions, which only provided a short-term boost . Co-author Mathew Whit. .专业知识分享 . .. WORD 格式整理 . .e, from the University of Exeter, UK, explained that thestudy showed people living in greener urban areas were displaying fewersigns of depression or anxiety . "There could be a number of reasons," he said,"for example,people do many things to make themselves happier:they strivefor promotion or pay rises,or they get married. But the trouble with those things is that within six months to a year,people are back to their original baseline levels of well-being. So, these things are notsustainable; they don't make us happy in the long term. We found that for some lottery ( 彩票) winners who had won more than ￡500,000 the positive effect was definitely there, butafter six months to a year, they were back to thebaseline."Dr. White said his team wanted to see whether living ingreener urban areashad a lasting positive effect on people's sense of well-being or whether the effect also disappeared after aperiod of time. To do this, the team used data from the British Household Panel Surveycompiled by the Universityof Essex.Explaining what the data revealed,he said:"What you see is that even after threeyears, mental health is still better, which is unlike many other things that we think will make ushappy." He observed that people living in green spaces were less stressed, and less stressedpeople made more sensible decisions and communicated better.With a growing body of evidence establishing a linkbetween urban green spaces and apositive impact on human well-being, Dr. White said,"There's growing interest among publicpolicy officials, but thetrouble is who funds it. What we really need at a policy level is todecide wherethe money will come from to help support good quality local green spaces."46. According to one study, what do green spaces do to people?A) Improve their work efficiency .B) Add to their sustained happiness.C)Help them build a positive attitude towards life.D)Lessen their concerns about material well-being.47.W hat does Dr. White say people usually do to make themselveshappier? A) Earn more money.B) Settle in an urban area.C) Gain fame and popularity .D) Live in a green environment .48. What does Dr. White try to find out about living in a greener urban area?A) How it affects different people.. .专业知识分享 . .. WORD 格式整理 . .B)How strong its positive effect is.C)How long its positive effect lasts.D)How it benefits people physically.49. What did Dr. White's research reveal about people living in agreenenvironment ?A)Their stress was more apparent than real.B) Their decisions requiredless deliberation . C) Their memories weregreatly strengthened .D)Their communication with others improved.50.A ccording to Dr. White, what should the government do tobuild more gre en spaces incities?A) Find financial support.B) Improve urban planning.C) Involve local residents in the effort.D) Raise public awareness of the issue .Passage TwoQuestions 51 to 55 are based on the following passage .You probably know about the Titanic, but it was actually just one of three state-of-the-art ( 先进的) ocean ships back in the day. The Olympic class ships were built by the Harland &amp;Wolff ship makers in Northern Ireland for the White StarLine company. The Olympic classincluded the Olympic, the Britannic and theTitanic. What you may not know is that the Titanicwasn't even the flagship ofthis class.All in all, the Olympic class ships were marvels ofseaengineering, but they seemed cursed to suffer disastrous fates.The Olympic launched first in 1910, followed by the Titanic in1911, and lastlythe Britannic in1914. The ships had nine decks, and White StarLine decidedto focus on making them themost luxurious ships on the water.Stretching 269.13 meters, the Olympic class ships were wonders of naval technology, andeveryone thought that they would continue to be so for quite some time. However, allsuffered terrible accidents on the open seas.The Olympic got wrecked before the Titanic did,but it was the only one to survive andmaintain a successful career of 24 years. The Titanicwas the firstto sink aft erfamously hitting a huge iceberg in 1912. Following this disaster ,the Britannic hit a naval mine in 1916 and subsequently sankas well.. .专业知识分享 . .. WORD 格式整理 . .Each ship was coal-powered by several boilers constantly kept running by ex hausted crewsbelow deck. Most recognizable of the ship designs are the shi p's smoke stacks, but thefourth stack was actually just artistic in nature and served no functional purpose. While twoof these ships sank, they were all de signed with double hulls ( 船体) believed to make them"unsinkable", perhaps a mistaken idea that led to the Titanic's and the Britannic's tragic end.The Olympic suffered two crashes with other ships and went on to serve as a hospital ship andtroop transport in World War I. Eventually, she was taken out of service in 1935, ending theera of the luxurious Olympic class ocean lin ers.51.W hat does the passage say about the three Olympicclass ships?

What is said about thefourth stack of the ships?A) It was a mere piece of decoration .B)It was the work of a famous artist.C)It was designed to let out extra smoke.D) It was easily identifiable from afar.54. What might have led to the tragic end of the Titanic and the Britannic?A) Their unscientific designs.B) Their captains' misjudgment .C) The assumption that they were built with the latest technology.D) The belief that they could never sink with a double- layer body.55.W hat happened to the ship Olympic inthe end? A) She was used to carry troops.B) She was sunk in World War I.C) She was converted into ahospital ship. D) She was retiredafter her naval service.. .专业知识分享 . .. WORD 格式整理 . .

Earlier this month ,the office asked for the public's help to measure their speed results ,saying consumers 28 to get the speeds they were promised. "Too many of us may be paying for one thing, and getting another, " the Attorney General said.If the investigation uncovers anything, it wouldn't be the fast time a telecom provider got into 29 over the broadband speeds it promised and delivered customers. Back in June, the Federal Communications Commission fined AT&T MYMlOO million over 30 that the carrier secretly reduced wireless speeds after customers consumed a certain amount of 31 .Even when they stay on the right side of the law, Internet providers arouse customers'anger over bandwidth speed and cost. Just this week, an investigation found that media and telecom giant Comcast is the most 32 provider. Over 10 months, Comcast received nearly 12,000 customer complaints, many 33 to its monthly data cap and ove ra ge (超过额度的）charges.Some Americans are getting so 34 with Internet providers they're just giving up.

In her search to live a life of purpose, Leah left her high-paying accounting job, her husband, and her home. In the process, she built a radically new life and career. S ince then, she has founded two yoga studios, met a new life partner, and formed a new community of people. Even if your personal reinvention is less drastic, we think there are lessons from her experience that apply.C)Where do the seeds of change come from? The Native American Indians have a saying: "Pay attention to the whispers so you won't have to hear the screams. "Often the best ideas for big changes come from unexpected places—it's just a matter of tuning in. Great leaders recognize the weak signals or slight signs that point to big changes to come. Leah reflects on a time she listened to the whispers: "About the time my daughter was five years old, I started having a sense that'this isn't right. "'She then realized that her life no longer matched her vision for it.D)Up until that point, Leah had followed traditional measures of success. After graduating with a degree in business and accounting, she joined a public accounting frrm, married, bought a house, put lots of stuff in it, and had a baby. " I did what everybody else thought looked successful ," she says. Leah easily could have fallen into a trap of feeling content; instead, her energy sparked a period of experimentation and renewal.E)Feeling the need to change, Leah started playing with future possibilities by exploring her interests anddeveloping new capabilities. First trying physical exercise and dieting, she lost some weight and discovered an inner strength. "I felt powerful because I broke through my own limitations, " she recalls.F)However, it was another interest that led Leah to radically reinvent herself. "I remember sitting on a bench with my aunt at a yoga studio, " she said, "and having a moment of clarity right then and there: Yoga is saving my life. Yoga is waking me up. I'm not happy and I want to change and I'm done with this. "In that moment of clarity Leah made an important leap , conquering her inner resistance to change and making a firm commitment to take bigger steps.G)Creating the future you want is a lot easier if you are ready to exploit the opportunities that come your way. When Leah made the commitment to change, she primed herself to new opportunities she may otherwise have overlooked. S he recalls:H)One day a man I worked with, Ryan, who had his office next to mine, said, "Leah, let's go look at this space on Queen Anne. " He knew my love for yoga and had seen a space close to where he lived that he thought might be good to serve as a yoga studio. As soon as I saw the location, I knew this was it. Of course I was scared, yet I had this strong sense of "I have to do this. "O nly a few months later Leah opened her first yoga studio, but success was not instant.I)Creating the future takes time. That's why leaders continue to manage the present while building toward the big changes of the future. When it's time to make the leap, they take action and immediately drop what's no longer serving their purpose. Initially Leah stayed with her accounting job while starting up the yoga studio to make it all work.J) Soon after, she knew she had to make a bold move to fully commit to her new future. Within two years, Leah shed the safety of her accounting job and made the switch complete. S uch drastic change is not easy.K) Steering through change and facing obstacles brings us face to face with our fears. Leah reflects on one incident that triggered her fears, when her investors threatened to shut her down: "I was probably up against the most fear I've ever had," she says. "I had spent two years cultivating this community, and it had become successful very fast, but within six months I was facing the prospect of losing it all. "L)She connected with her sense of purpose and dug deep, cultivating a tremendous sense of strength. " I was feeling so intentional and strong that I wasn't going to let fear just take over. I was thinking,'OK, guys, if you want to try to shut me down, shut me down.'And I knew it was a negotiation scheme ,so I was able to say tomyself,'This is not real.'" By naming her fears and facing them head-on, Leah gained confidence. For most of us, letting go of the safety and security of the past gives us great fear. Calling out our fears explicitly, as Leah did, can help us act decisively.M)The cycle of renewal never ends. Leah's growth spurred her to open her second studio—and it wasn't for the money.N)I have no desire to make millions of dollars. It's not about that; it's about growth for me. Honestly, I didn't need to open a second studio. I was making as much money as I was as an accountant. But I know if you don't grow, you stand still, and that doesn't work for me.0)Consider the current moment in your own life, your team or your organization. Where are you in the cycle ofrenewal: Are you actively preserving the present, or selectively forgetting the past, or boldly creating the future?What advice would Leah give you to move you ahead on your journey? Once we're on the path of growth, we can continually move through the seasons of transformation and renewal.36. R eadiness to take advantage of new opportunities will make it easier to create one's desired future.37. B y conventional standards, Leah was a typical successful woman before she changed her career.38. L eah gained confidence by laying out her fears and confronting them directly.39. I n search of a meaningful life, Leah gave up what she had and set up her own yoga studios.40. L eah's interest in yoga prompted her to make a frrm decision to reshape her life.41. S mall signs may indicate great changes to come and therefore merit attention.42. L eah's frrst yoga studio was by no means an immediate success.43. S ome people regard professional change as an unpleasant experience that disturbs their stable careers.44. The worst fear Leah ever had was the prospect of losing her yoga business.45. A s she explored new interests and developed new potentials, Leah felt powerful internally.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 andmark 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.Urbanization—migration away from the suburbs to the city center—will be the biggest real estate trend in 2015, according to a new report.The report says America's urbanization will continue to be the most significant issue affecting the industry, as cities across the country imitate the walkability and transit-oriented development making cities like New York and San Francisco so successful.As smaller cities copy the model of these "24-hour cities," more affordable versions of these places will be created. The report refers to this as the corning of the "18-hour city," and uses the term to refer to cities like Houston, Austin, Charlotte, and Nashville, which are "positioning themselves as highly competitive, in terms of livability, employment offerings, and recreational and cultural facilities. "Another trend that looks significant in 2015 is that America's largest population group, Millennials (千禧一代），will continue to put off buying a house. Apartments will retain their appeal for a while for Millennials, haunted by what happened to home-owning parents.This trend will continue into the 2020s, the report projects. After that, survey respondents disagree overwhether this generation will follow in their parents'footsteps, moving to the suburbs to raise families, or will choose to remain in the city center.Another issue affecting real estate in the coming year will be America's failing infrastructure. Most roads,bridges , transit , water systems , the electric grid , and communications networks were installed 50 to 100 years ago ,and they are largely taken for granted until they fail.The report's writers state that America's failure to invest in infrastructure impacts not only the health of the real­estate market, but also our ability to remain globally competitive.Apart from the specific trends highlighted above, which cause some investors to worry, the report portrays anoverall optimism borne by the recent healthy real-estate "upcycle" and improving economy. Seventy-four percent ofthe respondents surveyed report a" g ood to excellent" expectation of real-estate profitability in 2015. While excessive optimism can promote bad investment patterns, resulting in a real-estate "bubble, " the report's writers downplay thatpotential outcome in that it has not yet occurred. 46. According to the new report, real estate development in 2015 will witness .A)an accelerating speedB)a shift to city centersC)a new focus on small citiesD)an ever-increasing demand47. What characterizes "24-hour cities" like New York?A)People can live without private cars.B)People are generally more competitive.C)People can enjoy services around the clock.D)People are in harmony with the environment.48. Why are Millennials reluctant to buy a house?A)They can only afford small apartments.B)The house prices are currently too high.C)Their parents'bad experience still haunts them.D)They feel attached to the suburban environment.49. What might hinder real estate development in the U.S. ?A)The continuing economic recession in the country.B)The lack of confidence on the part of investors.C)The fierce global competition.D)The worsening infrastructure.50. How do most of the respondents in the survey feel about the U.S. real-estate market in 2015?A)Pessimistic.C)Cautious.Passage TwoB)Hopeful.D)Uncertain.Questions 51 to 55 are based on the following passage.The brain is a seemingly endless library, whose shelves house our most precious memories as well as ourlifetime's knowledge. But is there a point where it reaches capacity? The answer is no, because brains are more sophisticated than that. Instead of just crowding in, old informationis sometimes pushed out of the brain for new memories to form.Previous behavioural studies have shown that learning new information can lead to forgetting. But in a newstudy , researchers demonstrated for the first time how this effect occurs in the brain.In daily life, forgetting actually has clear advantages. Imagine, for instance, that you lost your bank card. Thenew card you receive will come with a new personal identification number (PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to relevant information, without old memories interfering.And most of us may sometimes feel the frustration of having old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory (where you are trying to remember new, but similar information) is particularly vulnerable to interference.When we acquire new information, the brain automatically tries to incorporate (合并）it within existing information by forming associations. And when we retrieve (检索）information ,both the desired and associated but irrelevant information is recalled.The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to place greater emphasis on the conditions under which we forget, as its importance begins to be more appreciated.A very small number of people are able to remember almost every detail of their life. While it may sound like an advantage to many, people with this rare condition often find their unusual ability burdensome.In a sense ,forgetting is our brain's way of sorting memories ,so the most relevant memories are ready for retrieval. Normal forgetting may even be a safety mechanism to ensure our brain doesn't become too full.51.What have past behavioural studies found about our brain?A)Its capacity actually knows no limits.B)It grows sophisticated with practice.C)It keeps our most precious memories until life's end.D)New information learned pushes old information out.52.What is the benefit of forgetting?A)It frees us from painful memories.B)It helps slow down our aging process.C)It fac1htates our access to relevant information.D)It prevents old information from forming associations.53.What is the emphasis of current studies of memory?A)When people tend to forget.B)What contributes to forgetting.C)How new technology hinders memory capacity.D)Why learning and forgetting are complementary.54.What do people find about their rare ability to remember every detail of their life?A)It adds to the burden of their memory.B)It makes their life more complicated.C)It contributes to their success in life.D)It constitutes a rare object of envy.55.What does the passage say about forgetting?A)It can enlarge our brain capacity.B)It helps get rid of negative memories.C)It is a way of organising our memories.D)It should not cause any alarm in any way.Part IV Translation (30 minutes)Directions : 几r this part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.黄河是亚洲第三、世界第六长的河流。

2020年大学英语四级考试真题及解析（第二套）一、PartⅠWriting(30minutes)1.Directions:For this part,you are allowed30minutes to write an essay on the use of PowerPoint(PPT)in class.You can start your essay with the sentence“The use of PowerPoint is becoming increasingly popular in class”.You should write at least120words but no more than180words.输入答案内容...【答案】【参考范文】In recent years,using PPT is becoming increasingly prevalent among teachers while having classes.PPT can present knowledge in a clearer way, which will be more convenient for students to digest.And for teachers, PPT also rescues them from writing on the blackboard,which is sometimes a heavy work.Besides,PPT can be saved and copied for students to review after class.But for people who prefer the traditional class,they think PPT can never replace the blackboard.As when having class with PPT,students have less time taking notes.Meanwhile,some teachers say preparing PPT is very time-consuming and not efficient at all.From what has been discussed above,PPT does have strengths and weaknesses.But I believe it brings so much convenience for us that we can ignore the few weakness it has.And when using it,we can still take the blackboard as an aid so as to present the class in the best way.【审题构思】本次考查的话题“PowerPoint”贴近于生活，让考生就课堂使用PPT的现象，发表自己的看法。
