For questions 1-7，markY (for YES) if the statement agrees with the information given in the passage;N (for NO) if the statement contradicts the information given in the passage;NG (for NOT GIVEN) if the information is not given in the passage.How Ice Cream Works The U.S. ice cream industry sells about a million gallons of ice cream each year，dispensing cones，gallons，pints，sundaes and other desserts through grocery stores and ice cream shops. In fact，eight percent of all the milk produced in the U.S. ends up in a frozen dairy product.Ice Cream or Frozen Dessert?Not just any frozen treat can be called ice cream. In fact，the U.S. Department of Agriculture has specific rules that define what can and can't be labeled "ice cream". To bear the "Meets USDA Ingredient Standard for Ice Cream" stamp，it has to contain at least 10 percent milk fat，and a minimum of six percent non-fat milk solids. A gallon has to weigh at least 4.5 pounds.The range of milk fat (sometimes referred to as butter fat) used in ice cream can go from the minimum 10 percent to a maximum of about 16 percent. Most premium ice creams use 14 percent milk fat. Higher fat content leads to better，richer taste and a creamier texture. Ice cream makers don't go higher than 16 percent because it would be costly and very high in calories. An ice cream with this much milk fat would also taste so rich that people would probably eat it in smaller amounts，which would be bad news for people who sell ice cream for a living.Other frozen desserts，such as sorbets (果汁冰糕)，low-fat ice cream，and frozen yogurt，are not technically ice cream at all. Frozen custard is ice cream that has at least 1.4 percent egg yolk solids，and "soft serve" can be any frozen milkbased dessert that has not gone through the hardening process—more on that later.In terms of specific ingredients，the recipe for ice cream is simple. But in scientific terms，it's complicated stuff. Ice cream is a colloid，a type of emulsion(乳状液). An emulsion is a combination of two substances that don't normally mix together. Instead，one of the substances is dispersed throughout the other. In ice cream，molecules of fat are suspended in a water-sugar-ice structure along with air bubbles. The presence of air meansthat ice cream is also technically a foam.In addition to milk fat，non-fat milk solids，sugar，and air，ice cream also contains stabilizers and emulsifiers. Stabilizers help hold the air bubble structure together and give the ice cream a better texture. Although gelatin(凝胶) was originally used as a stabilizer，xanthan gum，guar gum，and other compounds are used today. Emulsifiers keep the ice cream smooth and aid the distribution of the fat molecules throughout the colloid. Egg yolks were once used，but ice cream manufacturers now tend to use other chemical compounds. These stabilizers and emulsifiers make up a very small proportion (less than one percent) of the ice cream.Making Ice Cream Whether it's being made in your kitchen with a hand crank，at a local homemade ice cream shop with a stand-alone ice cream maker，or in a factory that cranks out thousands of gallons of ice cream every day，the process of making ice cream is basically the same. The only difference is the scale of the operation.First，you need ice cream mix. You can buy commercially made ice cream mix that is set to a certain milk fat content. Ice cream factories usually make their own mix by combining milk，cream and sugar in a 3,000 gallon vat，with the proportions and mixing controlled by computers. The mix is then pasteurized(用巴氏法灭菌)，or heated，to kill any harmful bacteria. If you were to make your own mix at home，you could pasteurize it by cooking it in a double boiler，or use an egg substitute or pasteurized egg product. This step is important because otherwise people who eat your homemade icecream could get sick due to salmonella contamination. According to the Centers for Disease Control，those most at risk include the elderly，very young children，and people with compromised immune systems.The next step in production is adding flavor to the mix. There are thousands of varieties of ice cream，so just about any combination of flavors is possible. From vanilla to cinnamon，chocolate to triple chocolate fudge brownie，it all gets blended into the ice cream mix. In a factory，this step takes place in vats that hold hundreds of gallons of ice cream，while giant steel paddles do the mixing. In your kitchen，a large bowl and a food mixer will work，or even a wooden spoon and muscle power if you want some exercise. Solid chunks such as pieces of fruit，chocolate chunks，marshmallows，and candy are added later.The next step is where and ice cream making machine comes into play. The mix has to be simultaneously frozen and whipped. In a factory，this happens in a giant tube surrounded by pipes. The pipes contain chemicals such as ammonia that freeze the tube，but the ammonia never comes into contact with the ice cream. The ice cream mix is pumped through the tube，where it gets cold very quickly. A dasher，or blade，turns inside the tube. This whips the mixture，introducing the air bubbles that help give ice cream its structure. The dasher also scrapes the sides of the tube，clearing off ice crystals that form there. This prevents large ice crystals from ruining the flavor and texture of the ice cream. All the elements of this process are carefully monitored and controlled by computers. Most homemade ice cream shops use a batch freezer for this step，where the same process happens ona smaller scale.This step can be accomplished at home with a rock salt/ice mixture for freezing and a hand or electric cranked dasher to mix and scrape off the ice crystals.Once the ice cream has come out of the ice cream maker，the process isn't finished. At this point，the mixture is frozen，but still soft. Large chunks of candy and other goodies are now added. Then the ice cream is placed into containers. Factory machines pour it straight into cartons or buckets，or it can be extruded(挤压出)into shapes that have wooden sticks placed into them for individual treats.Now the ice cream needs to be reduced to a very low temperature，zero degrees Fahrenheit or below. Factories make it even colder since they need the ice cream to stay frozen while it is packaged and loaded onto trucks. It needs to be very cold to freeze the ice cream quickly and prevent the formation of large ice crystals. This process is known as hardening. "Soft-serve" is often simply ice cream that has not gone through this process.We'll learn about the ice cream industry in the next section.Ice Cream Industry In 1999，retail sales of ice cream in the U.S.，the worldwide leader in ice cream production，topped $4 billion. In ，more that $20 billion was spent on frozen desserts. The leading states in ice cream consumption are California，Indiana，Pennsylvania，Texas and New York . Americans ate an average of 21.5 quarts of ice cream per person in .With that much money to be made，the ice cream industry can besecretive and underhanded(秘密). Deborah Hanny，owner of Sweet Jenny's Ice cream in Williamsville，NY，protects her recipes carefully. Her shop has been photographed by men in suits and she once caught someone in he upstairs office hurriedly trying to copy down her recipes.Ice cream making secrets are seldom passed down from generation to generation these days. So where do people in the ice cream industry learn their craft?At ice cream school. Pennsylvania State University offers a week-long "Ice Cream Short Course" intended for industry professionals. The course teaches the science and technology used to make ice cream. The also offer Ice Cream 101 for ice cream hobbyists who just want to learn more about their favorite frozen treat. The University of Guelph，Ontario's Dairy Science and Technology school，also has a long history of teaching ice cream science.1.

You may even have tried a fad diet or two，but found yourself right back whereyou started. The key to weight loss is regular 48 activity. And surprisingly，you don't have to give up eating or make the gym your second home to see long-term，49 effects.You body needs a certain amount of energy to maintain basic 50 such as breathing，blood circulation and digestion. The energy required to keep your organs functioning is referred to as the resting or basal metabolic rate.Any time you are active，51 energy is required. It is obtained from glycogen and fat stored in the blood，liver，and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.Which of the two energy sources you use depends on the intensity and 52 of your activity. The higher the intensity，the more your body will pull from the stored carbohydrates. The lower the intensity，the more your body will 53 on fat as its fuel.Aerobic exercise is most 54 for weight loss. When you perform aerobic activities you 55 contract large muscle groups such as your legs and arms. Walking，running，rollerblading，swimming，dancing，and jumping jacks are all forms of aerobic activity.Surprisingly，if your aerobic activity is low to moderately intense and of long duration，you will burn more fat than if you had 56 in a short burst of high-intensity exercise. In short，a brisk 30-minute walk will burn fat while a 100-yard sprint will burn glycogen.[A] positive[B] additional[C] duration[D] effective[E] shed[F] physical[G] food[H] functions[I] participated[J] rely[K] cut[L] repeatedly[M] uses[N] little[O] obviousSection B Directions：There are 2 passages in this section. Each passage is followed by some questions or unfinished statement. 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 center.Passage One Questions 57 to 61 are based on the following passage.There are many ways of defining success. It is accurate to say that each of us has our own concept of success to the extent that each of us is responsible for setting our own goals and determining whether we have met these goals satisfactorily. Because each of us possesses unique differences ingenetic ability and favorable environments in which to express these abilities，it is necessarily true that we must define success broadly.For some people，simply being able to live their life with a minimum of misery and suffering is considered a success. Think of the peace of mind of the poor shepherd who tends his sheep，enjoys his frugal life with his family in the beauty of nature，and who is respected because he does a good job of achieving the goals expected of and accepted by his and his society. On the other hand，it seems that even though some people appear to be rich in material possessions，many of them seem to be miserable and consider themselves unsuccessful when judged by their own standards of success. Because not all ventures can be successful，one should not set unrealistic goals for achieving success，but if one has self-confidence it would be unfortunate to set one's goals at too low a level of achievement.A wise counselor once said to a young man who was experiencing frustration with his own professional success："You do not have to set your goal to reach the moon in order to have success in traveling. Sometimes one can be very successful merely by taking a walk in the park or riding the subway downtown," The counselor added，" You have not really failed and spoiled your chances for success until you have been unsuccessful at something you really like，and to which you have given you best effort."57. In the first paragraph，the author implies that ________ are essential in achieving success.[A] ability and goals [C] ability and environment[B] goals and determination [D] goals and environment58. The word "frugal" (Line 2，Para. 2) means ________.[A] wealthy [C] thrifty[B] wasteful [D] miserable59. Some rich people consider themselves unsuccessful because ________.[A] their life is miserable [C] their goals are too low[B] they do not live in peace [D] they are not rich enough by their own standards.60. The last paragraph implies that ________.[A] we should have high goals [C] success means taking a walk in the park[B] success means achieving great goals [D] success means trying one's best at what onereally likes61. This passage mainly talks about ________.[A] the definition of success [C] how to set goals[B] how to achieve success [D] the importance of goalsPassage Two Questions 62 to 66 are based in the following passage.When Mike Kelly first set out to build his own private space-ferry service，he figures his bread-and-butter business would be lofting satellite into high earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly，who runs Kelly Space Technology，"I realized the real market is in space tourism."According to preliminary market surveys，there are 10,000 would-be space tourists willing to spend $1 million each to visit the final frontier. Space Adventures in Arlington have taken more than 130 deposits for a two-hour，$98,000 space tour tentatively set to occur by . This may sound great，but there are a few hurdles. Putting a simple satellite into orbit—with no oxygen，life support or return trip necessary—already costs and astronomical $2,200/kg. And that doesn't include the cost of insuring rich and possibly litigious(爱打官司)passengers. The entire group of entrepreneurs trying to corner the spacetourism market has between them "just enough money to blow up one rocket".The U.S. space agency has plenty of money but zero interest in making space less expensive for the little guys. So the little guys are racing to do what the government has failed to do：design a reusable launch system that's inexpensive，safe and reliable. Kelly Space's prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in California has a booster with rotors to make a helicopter-style return to earth. The first passenger countdowns are still years away，but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all，you can't be too prepared for a trip to that galaxy far，far away.62. Which of the following is the best title for the passage?[A] T ake Vacations in Space [C] Flight Regulations in Space Travels[B] Building Hotels in Space [D] Cost of Space Traveling63. The phrase "bread-and-butter business" (Line 1，Pare.1) mostprobably means ________.[A] a business to sell bread and butter [C] the business to make a living[B] a business to produce bread and butter [D] a traveling agency64. How much is the 2-hour space tour for each person according to Space Adventures in Arlington?[A] $1 million. [B] $10,000. [C] $98,000 [D] $22,00065. Which of the following is TRUE according to the passage?[A] The biggest hurdle for the space-tourism project is lack of a life supporting system.[B] The entrepreneurs trying to explore the space-tourism have plenty of money.[C] The government has little interests in this project.[D] The first passenger countdowns are within a few years.66. What's the author's tone in the last sentence of the passage?[A] Objective. [C] Approving.[B] Ironical. [D] Enthusiastic.Part V Cloze (15 minutes) Directions：There are 20 blanks in the following passage. For each blank there are four choices marked [A],[B],[C]and [D] on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on Answer Sheet 2 with a single line through the center.Reading involves looking at graphic symbols and formulating mentally the sounds and ideas they represent. Concepts of reading have changed 67 overthe centuries. During the 1950s especially，increased attention has been devoted to 68 and describing the reading process. 69 specialists agree that reading 70 a complex organization of higher mental 71 ，they disagree 72 the exact nature of the process. Some experts，who regard language primarily as a code using symbols to represent sounds，73 reading as simply the decoding of symbols to the sounds they stand 74 .These authorities 75 that meaning，being concerned with thinking，must be taught independently of the decoding process. Others maintain that reading is 76 related to thinking，and that a child who pronounces sounds without 77 their meaning is not truly reading. The reader，78 to some，is not just a person with a theoretical ability to read but one who 79 reads.Many adults，although they have the ability to read，have never read a book in its 80 . By some experts they would not be 81 as readers. Clearly，the philosophy，objectives，methods and materials of reading will depend on the definition one uses. By the most 82 and satisfactory definition，reading is the ability to 83 the soundsymbols' code of the language，to interpret meaning for various 84 ，at various rates，and at various levels of difficulty，and to do 85 widely and enthusiastically. 86 short，reading is the interpretation of ideas through the use of symbols representing sounds and ideas.67.

四级预测试卷及答案
四级考前冲刺试题一Part I Writing (30 minutes) Directions:For this part, you are allowed 30 minutes to write a short essay on the topic of Is Offering Seats Compulsory for Young Passengers? You should write at least 120 words according to the outline given below.1. 有人认为公交车上年轻人必须给老人让座2. 有人认为年轻人没有义务给老人让座3. 你的看法_Part II Reading Comprehension (15 minutes)Eat an Apple (Doctor’s Orders)The farm stand is becoming the new apothecary (药剂师), preparing and giving out apples — not to mention vegetables such as artichokes, asparagus and arugula — to fill a novel kind of prescription.Doctors at three health centers in Massachusetts have begun advising patients to eat “prescription produce” from local farmers’ markets, in an effort to fight o besity (when someone is very fat in a way that is unhealthy) in children of low-income families. Now they will give coupons (赠券) amounting to $1 a day for each member of a patient’s family to promote healthy meals.“A lot of these kids have a very limited range of fruits and vegetables that are acceptable and familiar to them. Potentially, they will try more,” said Dr. Suki Tep perberg, a family physician at Codman Square Health Center in Dorchester, one of the program sites. “The goal is to get them to increase their consumption of fruit and vegetables by one serving a day.”The effort may also help farmers’ markets compete with fast-food restaurants selling dollar value meals. Farmers’ markets do more than $1 billion in annual sales in the United States, according to the Agriculture Department.Massachusetts was one of the first states to promote these markets as hubs of preventive health. In the 1980s, for example, the state began issuing coupons for farmers’ markets to low-income women who were pregnant or breast-feeding or for young children at risk for malnutrition (营养不良). Thirty-six states now have such farmers’ market nutri tion programs aimed at women and young children.Thomas M. Menino, the mayor of Boston, said he believed the new children’s program, in which doctors write vegetable “prescriptions” to be filled at farmers’ markets, was the first of its kind. Doctors will track participants to determine how the program affects their eating patterns and to monitor health indicators like weight and body mass index, he said.“When I go to work in the morning, I see kids standing at the bus stop eating chips and drinking a sod a,” Mr. Menino said in a phone interview earlier this week. “I hope this will help them change their eating habits and lead to a healthier lifestyle.”The mayor’s attention to healthy eating dates to his days as a city councilman. Most recently he has appointed a well-known chef as a food policy director to promote local foods in public schools and to foster market gardens in the city.Although obesity is a complex problem unlikely to be solved just by eating more vegetables, supporters of the vegetable coupon program hope that physician intervention will spur young people to adopt the kind of behavioral changes that can help prevent lifelong obesity.Childhood obesity in the United States costs $14.1 billion annually in direct health expenses like prescription drugs and visits to doctors and emergency rooms, according to a recent article on the economics of childhood obesity published in the journal Health Affairs. Treating obesity-related illness in adults costs an estimated $147 billion annually, the article said.Although the vegetable prescription pilot project is small, its supporters see it as a model for encouraging obese children and their families to increase the volume and variety of fresh produce they eat.“Can we help people in low-income areas, who shop in the center of supermarkets for low-costempty-calorie food, to shop at farmers’ markets by making fruit and vegetables more affordable?” said Gus Schumacher, the chairman of Wholesome Wave, a nonprofit group in Bridgeport, Conn., that supports family farmers and community access to locally grown produce.If the pilot project is successful, Mr. Schumacher said, “farmers’ markets would become like a fruit and vegetable pharmacy (药房) for at-risk families.”The pilot project plans to enroll up to 50 families of four at three health centers in Massachusetts that already have specialized children’s programs called healthy weight clinics.A foundation called CAVU, for Ceiling and Visibility Unlimited, sponsors the clinics that are administering the vegetable project. The Massachusetts Department of Agriculture and Wholesome Wave each contributed $10,000 in seed money. (Another arm of the program, at several health centers in Maine, is giving fresh produce coupons to pregnant mothers.) The program i s to run until the end of the farmers’ market season in late fall.One month after Leslie-Ann Ogiste, a certified nursing assistant in Boston, and her 9-year-old son, Makael Constance, received their first vegetable prescription coupons at the Codman Center, they have lost a combined four pounds, she said. A staff member at the center told Ms. Ogiste about a farmers’ market that is five minutes from her apartment, she said.“It worked wonders,” said Ms. Ogiste, who bought and prepared eggplant, cucumbers,tomatoes, summer squash, corn, bok choy, parsley, carrots and red onions. “Just the variety, it did help.”Ms. Ogiste said she had minced some vegetables and used them in soup, pasta sauce and rice dishes —the better to disguise the new good-for-you foods that she served her son.Makael said he did not mind. “It’s really good,” he said.Some nutrition researchers said that the Massachusetts project had a good chance of improving eating habits in the short term. But, they added, a vegetable prescription program in isolation may not have a long-term influence on reducing obesity. Families may revert to their former habits in the winter when the farmers’ markets are closed, these researchers said, or they may not be able to afford fresh produce after the voucher program ends.Dr. Shikha Anand, the medical director of CAVU’s healthy weight initiative, said the group hoped to make the veggie prescription project a year-round program through partnerships with grocery stores.But people tend to overeat junk food in higher proportion than they undereat vegetables, said Dr. Deborah A. Cohen, a senior natural scientist at the RAND Corporation. So, unless people curtail (减少) excessive consumption of salty and sugary snacks, she said, behavioral changes like eating more fruit and vegetables will have limited effect on obesity.In a recent study led by Dr. Cohen, for example, people in southern Louisiana typically exceeded guidelines for eating salty and sugary foods by 120 percent in the course of a day while falling short of vegetable and fruit consumption by 20 percent.The weight clinics in Massachusetts chosen for the vegetable prescription test project already encourage families to cut down on unhealthy snacks.Even as Ms. Ogiste and her son started shopping a t the farmers’ market and eating more fresh produce, for example, they also cut back on junk food, she said.“We have stopped the snacks. We are drinking more water and less soda and less juice too,” Ms. Ogiste said. “All of that helped.”1.

You may not use any of the words in the bank more than once.Questions 47 to 56 are based on the following passage.There was a time when red meat was a luxury for ordinary Americans, or was at least something special: cooking a roast for Sunday dinner, ordering a steak at a restaurant. Not anymore. Meat consumption has more than 47 in the United States in the last 50 years.Now a new study of more than 500,000 Americans has provided the best 48 that our love for red meat has exacted a high price on our health and limited our life span. The study found that, other things being 49 , the men and women who consumed the most red and processed meat were likely to die sooner, 50 from one of our two leading killers, heart disease and cancer, than people who consumed much 51 amounts of these foods.To prevent deaths 52 to red and processed meats, people should eat a hamburger only once or twice a week instead of every day, a small steak once a week instead of every other day, and a hot dog every month and a half instead of once a week. In 53 of red meat, non-vegetarians (非素食者) might consider poultry and fish. Likewise, those who ate the most fruits and vegetables also tended to live 54 .Anyone who worries about global well-being has yet another reason to consume less red meat. A reduced 55 on red meat for food could help to save the planet from the 56 effects ofSection BDirections: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 57 to 61 are based on the following passage.The work on atmospheric chlorofluorocarbons (氯氟化碳) led eventually to a global CFC ban that saved us from ozone-layer reduction. Do we have time to do a similar thing with carbon emissions to save ourselves from climate change?Not a hope at all. Most of the “green” stuff is very close to a big trick. Carbon trading, with its huge government grants, is just what finance and industry wanted. It’s not going to do a thing about climate change, but it’ll make a lot of money for a lot of people and postpone the moment of reckoning.I am not against renewable energy, but to spoil all the decent countryside in the UK with wind farms is driving me mad. It’s absolutely unnecessary, and it takes 2,500 square kilometers to produce a gigawatt (十亿瓦特) —that’s an awful lot of countryside.Work to sequester (隔离) CO2(carbon dioxide) is also a waste of time. It’s a crazy idea — and dangerous. It would take so long and use so much energy that it will not be done.And, nuclear power is a way for the UK to solve its energy problems, but it is not a global cure forclimate change. It is too late for emissions reduction measures.Yet we are not doomed. There is one way we could save ourselves and that is through the massive burial of charcoal (木炭). It would mean farmers turning all their agricultural waste — which contains carbon that the plants have spent the summer sequestering — into charcoal, and burying it in the soil. Then you can start shifting vast quantities of carbon out of the system and pull the CO2 down quite fast.What we can do is getting farmers to burn their crop waste at very low oxygen levels to turn it into charcoal, which the farmer then ploughs into the field. A little CO2 is released but the bulk of it gets converted to carbon. You get a few per cent of bio-fuel as an additional product of the burning process, which the farmer can sell. This scheme would need no subsidy (补贴): the farmer would make a profit. This is the one thing we can do that will make a difference.57. According to the passage, carbon trading .A) probably saves people from climate changeB) benefits some financially but not environmentallyC) has contributed a lot to carbon emissions reductionD) makes huge money for governments around the world58. What does the author say about wind farms in Britain?A) The gain does not equal to the loss.B) They can help solve world’s energy problems.C) They would be perfect if they take up smaller space.D) They will waste the government lots of time and money.59. W hat’s the author’s opinion on nuclear power?A) It’s one of the emission reduction measures that should be advocated.B) It’s only applicable to Britain but not the whole world in emission reduction.C) It’s of no help to the current global climate as a sl ow way to pull CO2 down.D) It’s a good way to solve both the energy and pollution problems in the world.60. To reduce carbon emission fast in the world, the author suggests .A) capturing and sequestering CO2 in the airB) building more nuclear power plantsC) planting more trees to absorbing CO2D) burying burnt crop waste into the field61. According to the passage, one advantage of the author’s proposal is that .A) it can produce charcoal most of which can be used as fuelB) it does n’t involve any international cooperation or negotiationC) it brings extra income to farmers and saves government moneyD) it needs no advanced technology or expensive equipmentPassage TwoQuestions 62 to 66 are based on the following passage.A few years back, the decision to move the Barnes, a respected American art institution, from its current location in the suburban town of Merion, Pa., to a site in Philadelphia’s museum district caused an argument — not only because it shamelessly went against the will of the founder, Albert C. Barnes, but also because it threatened to dismantle (拆开) a relationship among art, architecture and landscape critical to the Barnes’s success as a museum.For any architect taking on the challenge of the new space, the confusion of moral and design questions might seem overwhelming. What is an architect’s responsibility to Barnes’s vision of a marvelous but odd collection of early Modern artworks housed in a rambling(布局凌乱的) 1920s Beaux-Arts pile? Is it possible to reproduce its spirit in such a changed setting? Or does trying to replicate (复制) the Barnes’s unique atmosphere only doom you to failure? The answers of the New York architects taking the commission are not reassuring.The new Barnes will include many of the features that have become virtually mandatory (强制性的) in the museum world today —conservation and education departments, temporary exhibition space, auditorium, bookstore, café— making it four times the size of the old Barnes. The architects have tried to compensate for this by laying out these spaces in an elaborate architectural procession that is clearly intended to replicate the peacefulness, if not the fantastic charm, of the old museum.But the result is a complicated design. Almost every detail seems to ache from the strain of trying to preserve the spirit of the original building in a very different context. The failure to do so, despite such an earnest effort, is the strongest argument yet for why the Barnes should not be moved in the first place.The old Barnes is by no means an obvious model for a great museum. Inside the lighting is far from perfect, and the collection itself, mixing masterpieces by Cézanne, Picasso and Soutine with second-rate paintings by lesser-known artists, has a distinctly odd flavor. But these apparent flaws are also what have made the Barnes one of the country’s most charming exhibition spaces.But today the new Barnes is after a different kind of audience. Although museum officials say the existing limits on crowd size will be kept, it is clearly meant to draw bigger numbers and more tourist dollars. For most visitors the relationship to the art will feel less immediate.62. The Old Barnes becomes the successful museum mainly because of .A) the beneficial geographical position in a suburban townB) its unique design and orderly collection of artsC) the influence of its founder Albert C. BarnesD) the perfect connection among art, architecture and landscape63. The biggest challenge architects face in building the new Barnes is .A) the ethical and design problemsB) the difficulty to retain its original peacefulnessC) the lack of confidence in undertaking the taskD) the difficulty to put all the artworks in a smaller space64. According to the passage, the new Barnes will .A) be completely the same as the old one B) take up more space than the old oneC) be changed into an art education center D) be forced to be modern in appearance65. Why does the author oppose to relocate the Barnes?A) The relocation means disrespect to the person who runs it.B) Architectures’ complicated desi gn will make the museum charmless.C) The spirit of the old Barnes will be gone in a different place.D) The multiple functions of the new Barnes will destroy the collection.66. What do we know about the old Barnes from the fifth paragraph?A) It is a good example of the great modern museums.B) It is downgraded by the mixture of different paintings.C) The world-famous painters’ works make it a charming place.D) It is the seeming imperfection that makes it attractive.Part V Cloze (15 minutes)Directions:There are 20 blanks in the following passage.

Words become 74 with meaning for us by experience; and the 75 we live, the more certain words 76 to us the happy and sad 77 of our past; and the more we read and learn, the more the number of words that mean something to us 78 .Great writers are those who not only have great thoughts but also express these thoughts in words which appeal 79 to our minds and emotions. This 80 and telling use of words is what we call 81 style. 82 all, the real poet is a master of words. He can 83 his meaning in words which sing like music, and 84 by their position and association can 85 men to tears.

大学英语四级考试模拟试题7（标准答案）Part I WritingComputer Games on CampusToday, many college students are absorbed in playing computer games. Maybe there is some truth in the statement that computer games are fun and will train one's reactivity, determination, and attention.However, the merits of computer games can never compensate for the negative effects they have. First, it is very time-consuming to play computer games. The game fans have sacrificed almost all their time thus they have no time to attend class, to take exercises, or even to date. Upon graduation many will regret that they have wasted the precious college time on nothing. Second, those who play computer games excessively would easily fall victim to various illnesses. For example, game fans always fix their eyes on the screen; therefore, they are likely to be near-sighted. Third, the game fans, who spend their time before the lifeless computers, usually overlook their relationship with others. They would find that they have some mental or psychic problems.Part II Reading Comprehension (Skimming and Scanning)这篇文章向人们介绍了在五一外出度假期间怎样保持女人漂亮本色。

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.Take Naps at Work.Apologize to No One[A]In the past two weeks I’ve taken three naps at work,a total of an hour or so of shut-eye while on the clock.And I have no shame or uncertainty about doing it.I couldn’t feel better about it,and my productivity reflects it,too.[B]Sleeping on the job is one of those workplace taboos-like leaving your desk for lunch or taking an afternoon walk-that we’re taught to look down on.If someone naps at2p.m.while the rest of us furiously write memos and respond to emails,surely it must mean they’re slacking off(偷懒).Or so the assumption goes.[C]Restfulness and recharging can take a back seat to the perception and appearance of productivity.It’s easier to stay on a virtual hamster(仓鼠)wheel of activity by immediately responding to every email than it is to measure aggregate productivity over a greater period of time.But a growing field of occupational and psychological research is building the case for restfulness in pursuit of greater productivity.[D]Companies are suffering from tremendous productivity problems because people are stressed out and not recovering from the workday,said Josh Bersin,Principal and Founder of Bersin by Deloitte.“They’re beginning to realize that this is their problem,and they can’t just say to people,‘Here’s a work-life balance course,go teach yourself how to manage your inbox,’”Mr.Bersin said.“It’s way more complicated than that.”[E]To be sure,the ability to nap at work is far from widespread,experts said.Few among us have the luxury of being able to step away for a half-hour snoozefest.But lunch hours and coffee breaks can be great times to duck out,and your increased productivity and alertness will be all the evidence you need to make your case to inquiring bosses.[F]In an ideal world,we’d all solve this problem by unplugging early and getting a good night’s sleep. Here’s our guide on how to do just that.But the next best thing is stealing away for a quick power nap when you’re dragging after lunch.[G]In a study published in Nature Neuroscience,researchers tested subjects on their perceptual performance four times throughout the day.Performance deteriorated with each test,but subjects who took a30-minute nap between tests stopped the deterioration in performance,and those who took a60-minute nap even reversed it.[H]“Naps had the same magnitude of benefits as full nights of sleep if they had a quality of nap.”said Sara Mednick,a co-author of the study and associate professor of psychology at the University of California,Riverside.[I]Dr.Mednick,a sleep researcher and the author of Take a Nap!Change Your Life,said daytime napping can have many of the benefits of overnight sleep,and different types of naps offer specific benefits.[J]For example,Dr.Mednick said a20-to60-minute nap might help with memorization and learning specific bits of information.It’s just long enough to enter stage-two sleep,or non-rapid eye movement(R.E.M.)sleep.[K]After60minutes,you start getting into R.E.M.sleep,most often associated with that deep,dreaming state we all enjoy at night R.E.M.sleep can improve creativity,perceptual processing and highly associativethinking,which allows you to make connections between disparate ideas,Dr.Mednick said.Beyond that,your best bet is a90-minute nap,which will give you a full sleep cycle.[L]Any nap,however,can help with alertness and perception and cut through the general fog that creeps in during the day,experts said.[M]So how did we even arrive at this point where aptitude is inextricably tied(紧密相连)to working long, concentrated hours?Blame technology,but think broader than smartphones and laptops;the real issue is that tech has enabled us to be available at all times.[N]“We went through a period where people were in denial and business leaders were ignoring it,”Mr. Bersin said.“They were assuming that if we give people more tools,more emails,more Slack,more chatter,and we’ll just assume they can figure out how to deal with it all.And I think they’ve woken up to the fact that this is a big problem,and it is affecting productivity,engagement,health,safety,wellness and all sorts of things.”[O]It isn’t just office workers who can benefit from an afternoon siesta(午睡).A2015study published in Current Biology looked at the at the sleeping habits of three hunter-gatherer preindustrial societies in Tanzania, Namibia and Bolivia.[P]“They’re active in the morning,then they get in the shade under the trees and have a sort of quiet time, but they’re not generally napping,”said Jerome Siegel,professor of psychiatry and biobehavioral sciences,and director of the U.C.L.A.Center for Sleep Research,a co-author of the study.“Then they do some work and go to sleep,and they sleep through the night.”[Q]Still,Mr.Siegel said,“the only genuine way to solve daytime sleepiness and fatigue starts the night before with a solid night’s sleep.”The real Holy Grail of restfulness is a regular sleep schedule with ideally seven or eight hours of sleep each night,which experts say is optimal.[R]“Daytime napping certainly does increase alertness,”Mr.Siegel said.“But it’s not as simple as going to the gas station and filling the tank.”[S]He also advises avoiding caffeine late in the day and waking around the same time every morning,even if you can’t get to sleep at the same time every night,This helps acclimate(使适应)your body to your regular wake-up time,regardless of how much sleep you got the night before.[T]So if you’ve made it this far and you’re interested in giving workday naps a try(or just starting to nod off),here’s a quick guide to the perfect nap;Find a quiet,unoccupied space where you won’t be disturbed.Try to make your area as dim as possible(or invest in a sleep mask you can keep in the office).Earplugs might help.too.Aim for around20minutes.Any longer than that and you’re likely to wake up with sleep inertia(睡眠惰性)，which will leave you even groggier(头脑昏沉的)than before.36.Participants’perceptual performance became better after sleeping one hour between tests in an article inNature Neuroscience.37.Jerome Siegel found that only by sleeping soundly through the previous night could people tackle theirweariness during the day.38.Our talent is closely bound to working with concentration for long periods of time because technologymakes us accessible24/7.39.Taking a nap at work is normally regarded as laziness that should be held in contempt and avoided inworkplace.40.Between20to60minutes,people can get into non-REM sleep which may improve memory and learningability according to Dr.Mednick.41.People can doze off at lunch and coffee breaks and defended themselves by saying their improvedproductivity and alertness when bosses investigated their whereabouts.42.The author’s tips on taking a perfect nap involve sleeping place,environment and duration.43.The author believes business leaders are aware that availability at any time due to technology has negativeeffects on every aspect of people’s life.44.The optimal length of a nap was an hour and a half so that people could go through a complete sleep cycle.45.Josh Bersin mentioned the cause of companies’big productivity problems and the solution which needsmore that just employees’efforts.Section CDirections:There are2passages 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 Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.Every office worker hates meetings.But it’s a strange sort of hate,similar to the hatred of Londoners for the Northern Line,or New Yorkers for tourists who walk too slowly:the dislike is real,yet if the despised thing were to vanish,it’d be like surrendering a piece of your soul.When researchers probed into why people put up with the strain that meetings place on their time and sanity, they found something-those who resent and dread meetings the moat also defend them as a“necessary evil”, sometimes with great passion.True,research suggests that meetings take up vastly more of the average manager’s time than they used to.True,done badly,they’re associated with lower levels of innovation and employee wellbeing(幸福).But that’s just office life,right?It’s not supposed to be fun.That’s why they call it work.Underlying(引起)this attitude is an assumption that’s drummed into us not just as workers but as children, parents and romantic partners;that more communication is always a good thing.So suggestions abound for(大量存在)communicating better in meetings-for example,hold them standing up,so speakers will come to the point more quickly.But even when some companies consider abolishing meetings entirely,the principle that more communication is better isn’t questioned.If anything,it’s reinforced when such firms introduce“flat”management structures,with bosses always available to everyone,plus plenty of electronic distraction.In fact,constant connectivity is disastrous for both job satisfaction and the bottom line.And anyway,once you give it three seconds’thought,isn’t it cleat that more communication frequently isn’t a good thing?Often,the difference between a successful marriage and a second-rate one consists of leaving about three or four things a day unsaid.At work,it’s surely many more than four,though for a different reason;office communication comes at the cost of precisely the kind of focus that’s essential to good work.Yet we’re so accustomed to seeing talking as a source of solutions-for resolving conflicts or finding new ideas-that it’s hard to see when it is the problem.46.What does the author say about meetings?A)Londoners hate them as well as the Northern Line.B)They can help to keep workers’physical and spiritual health.C)Workers might be reluctant to give up them completely.D)New Yorkers dislike meetings more than Londoners.47.What did researchers find about people’s attitude towards meeting?A.Their attitude and behavior are paradoxical.B)People who hate meetings the most are senior insane.C)Those who like meetings might be considered insane.D)More meetings are regarded as a sign of less innovation.48.Why do people think that more communication is always a good thing?A)Because the concept is firmly believed by workers.B)Because everyone loves to communicate with others.C)Because the idea has been instilled into people’s mind.D)Because communication is vital for building relationships.49.What does the author think of the“flat”management structure?A)It forces bosses to frequently contact their employees.B)It helps to soften employees’bottom line of work.C)It is definitely a disaster to employees’job satisfaction.D)It strengthens people’s deeply-rooted notion of communication.50.What is the author’s argument about office communication?A)It is an effective way to solve office conflicts.B)It affects work efficiency in a negative way.C)It should come to a halt at intervals.D)It is useful for workers to find new ideas.Passage TwoQuestions51to55are based on the following passage.The Internet has enabled the spread of information at lightning speed.This information revolution has created tremendous business opportunities for online publishers,but not all of them maintain proper quality-control mechanisms to ensure that only good information is being shared.Instead,many publishers aim simply to make money by whatever means possible,with no regard for the implications for society at large.When selfish publishers set up shops online,the primary goal is to publish as much as possible,often at the cost of quality.In this respect,many publishers start numerous online journals focused on overlapping(重叠的)disciplines—to increase their total number of published papers—and hire young business managers who do not have any experience in either science or publishing.In some cases,online publishers even give up peer review, while still presenting themselves as scientific journals—deception designed to take advantage of scientists who simply want to share their research.If publishers structure their business to make more revenue,it often does harm to their products.When publishers start journals with overlapping domains,in combination with the pressure to publish more studies,this could promote the publication of marginal or even questionable articles.Moreover,publishers with multiple overlapping journals and journals with very narrow specialties(专业)increase the demands on the time and efforts of willing reviewers.With the fact that reviewers are generally not compensated for their time and effort,journal editors are often unable to find enough reviewers to keep up with the increased publication rate.To improve the situation and increase the trust in scientific community,the pressure to publish must be reduced.Funding and promotion decisions should not be based on the number of publications,but on the quality of those publications and a researcher’s long-term productivity and instructions.And that’s just the start.We need additional mechanisms,such as Beall’s list of predatory(掠夺的)publishers, to alert scientists to fake journals and fake articles.In addition,the price for online publication must be controlled and a mechanism must be put in place to honor and reward hard-working reviewers.51.What does the author think of online publishers?A)A small proportion of them can guarantee their publishing quality.B)They have lots of opportunities to renovate their business models.C)Many of them tend to try every means to make a buck.D)Social impact is their first priority when publishing books.52.It can be inferred from the second paragraph that______.A)peer review generally is a criterion to identify academic journalsB)researchers focus their research on the combination of disciplinesC)scientists care about their publications rather than researchD)young business managers are willing to face new challenges53.Why can’t publishers find enough reviewers to review papers?A)Reviewers are pressed for time when reviewing articles.B)Reviewers’gains can’t make up for what they have done.C)Publishers may compel reviewers to accept marginal articles.D)Publishers urge reviewers to increase publication rate rapidly.54.What is the author’s suggestion for online publication?A)More weight should be put on the quantity of publications.B)It is worthwhile to reward diligent reviewers for their effort.C)Fake journals should be reported to a regulatory organization.D)The price of online publication should be lowered greatly.55.What is the main idea of this passage?A)Online publishers should take measures to fight against fake scientific journals.B)Online publishers are pursuing their work efficiency at the cost of quality.C)Online publishers business models are quite likely to harm their publications.D)Online publishers are sacrificing the quality of research articles to make money.PartⅣTranslation(30minutes)Directions:For this part,you are allowed30minutes to translate a passage from Chinese intoEnglish.You should write

Key to Model Test Two Part I Writing 【写作思路】 本⽂是⼀篇关于代沟的论⽂。
从代沟的现象开始讨论，接着提出代沟产⽣的家庭原因以及社会原因。
【参考范⽂】 Generation Gap Generation gap seems a hot topic between the old and the young. Parents complained that children didn’t show them proper respect and obedience, while children complained that their parents didn’t understand them at all. Often they discover that they have very little in common. One cause of the generation gap is the opportunity that young people have to choose their own life. In traditional societies, children live in the same area as their parents, marry people their parents know and approve of, and often continue the family occupation. In our society, people often move out of the home at an early age, marry or live with people their parents have never met, and choose occupations that are rather different. Parents often expect their children to be better than them. However, these ambitions for their children are another cause of the division between them. Finally, the speed of change in our society is another cause of it. In a traditional culture, people are valued for their wisdom, but in our society the knowledge of a lifetime may become out of date. No doubt, the generation gap will continue to be a feature of our life. Its causes are rooted in the freedoms and opportunities of our society, and in the rapid pace at which society changes.

However, to his great surprise, the hospital bill is far beyond what he can afford. The old man is so shocked that he cannot stand on his feet. It hits him just like another heart attack.At present, with the medical expenses continuously going up, more and more people feel it difficult for them to pay for their fundamental health care. Many families with patient members get into heavy debts, espe-cially those who live in rural areas; worse still, some patients even have to wait for their ends hopelessly. Obvi-ously, this situation doesn’t contribute to the harmony of our society and holds back our social development as well.Therefore, we strongly call for reform in public health care so that everyone in our country can have an easy and equal access to necessary medical treatment. Effective measures should be taken to make sure that ev-ery citizen can enjoy a healthy and longer life.写作思路:这是一篇议论文,要求考生对现在普遍存在的就医费用高做阐述,文章内容安排如下:第一段:对图画进行简单的描述,指出重点:就医费用高。

Then imagine dust storms sweeping up toxic pesticides and chemical fertilizers from the dry seabed and spewing them across towns and villages.Seem like a scene from a movie about the end of the world? For people living near the Aral Sea in Central Asia, it’s all too real. Thirty years ago, government planners diverted the rivers that flow into the sea in order to irrigate（provide water for）farmland. As a result, the sea has shrunk to half its original size, stranding ships on dry land. The seawater has tripled in salt content and become polluted, killing all 24 native species of fish.Similar large-scale efforts to redirect water in other parts of the world have also ended in ecological crisis, according to numerous environmental groups. But many countries continue to build massive dams and irrigation systems, even though such projects can create more problems than they fix. Why? People in many parts of the world are desperate for water, and more people will need more water in the next century.“Growing populations will worsen problems with water,” says Peter H. Gleick, an environmental scientist at the Pacific Institute for studies in Development, Environment, and Security, a research organization in California. He fears that by the year 2025, as many as one third of the world’s projected 8.3 billion people will suffer from water shortages.Where Water GoesOnly 2.5 percent of all water on Earth is freshwater, water suitable for drinking and growing food, says Sandra Postel, director of the Global Water Policy Project in Amherst, Mass. Two thirds of this freshwater is locked in glaciers and ice caps. In fact, only a tiny percentage of freshwater is part of the water cycle, in which water evaporates and rises into the atmosphere, then condenses and falls back to Earth as precipitation（rain or snow）.Some precipitation runs off land to lakes and oceans, and some becomes groundwater, water that seeps into the earth. Much of this renewable freshwater ends up in remote places like the Amazon river basin in Brazil, where few people live. In fact, the world’s population has access to only 12,500 cubic kilometers of freshwater—about th e amount of water in Lake Superior. And people use half of this amount already. “If water demand continues to climb rapidly,” says Postel, “there will be severe shortages and damage to the aquatic environment.”Close to HomeWater woes may seem remote to people living in rich countries like the United States. But Americans could face serious water shortages, too especially in areas that rely on groundwater. Groundwater accumulates in aquifers, layers of sand and gravel that lie between soil and bedrock. （For every liter of surface water, more than 90 liters are hidden underground.）Although the United States has large aquifers, farmers, ranchers, and cities are tapping many of them for water faster than nature can replenish it. In northwest Texas, for example, over pumping has shrunk groundwater supplies by 25 percent, according to Postel.Americans may face even more urgent problems from pollution. Drinking water in the United States is generally safe and meets high standards. Nevertheless, one in five Americans every day unknowingly drinks tap water contaminated with bacteria and chemical wastes, according to the Environmental Protection Agency. In Milwaukee, 400,000 people fell ill in 1993 after drinking tap water tainted with cryptosporidium, a microbe that causes fever, diarrhea and vomiting.The SourceWhere do contaminants come from? In developing countries, people dump raw sewage into the same streams and rivers from which they draw water for drinking and cooking; about 250 million people a year get sick from water borne diseases.In developed countries, manufacturers use 100,000 chemical compounds to make a wide range of products. Toxic chemicals pollute water when released untreated into rivers and lakes. (Certain compounds, such as polychlorinated biphenyls, or PCBs, have been banned in the United States.）But almost everyone contributes to water pollution. People often pour household cleaners, car antifreeze, and paint thinners down the drain; all of these contain hazardous chemicals. Scientists studying water in the San Francisco Bay reported in 1996 that 70 percent of the pollutants could be traced to household waste.Farmers have been criticized for overusing herbicides and pesticides, chemicals that kill weeds and insects but that pollute water as well. Farmers also use nitrates, nitrogen-rich fertilizer that help plants grow but that can wreak havoc on the environment. Nitrates are swept away by surface runoff to lakes and seas. Too many nitrates “over enrich” these bodies of water, encouraging the buildup of algae, or microscopic plants that live on the surface of the water. Algae deprive the water of oxygen that fish need to survive, at times choking off life in an entire body of water.What’s the Solution?Water expert Gleick advocates conservation and local solutions to water-related problems; governments, for instance, would be better off building small-scale dams rather than huge and disruptive projects like the one that ruined the Aral Sea.“More than 1 billion people worldwide don’t have access to basic clean drinking water,”says Gleick.“There has to be a strong push on the part of everyone—governments and ordinary people—to make sure we have a resource so fundamental to life.”1. That the huge water projects have diverted the rivers causes the Aral Sea to shrink.2. The construction of massive dams and irrigation projects does more good than harm.3. The chief causes of water shortage are population growth and water pollution.4. The problems Americans face concerning water are groundwater shrinkage and tap water pollution.5. According to the passage all water pollutants come from household waste.6. The people living in the United States will not be faced with water shortages.7. Water expert Gleick has come up with the best solution to water-related problems.1.［Y］［N］［NG］2.［Y］［N］［NG］3.［Y］［N］［NG］4.［Y］［N］［NG］5.［Y］［N］［NG］6.［Y］［N］［NG］7.［Y］［N］［NG］8. According to Peter H. Gleick, by the year 2025, as many as of the world’s people will suffer from water shortages.9.Two thirds of the freshwater on Earth is locked in.10.In developed countries, before toxic chemicals are released into rivers and lakes, they should be treated in order to avoid.Part III Listening Comprehension (35 minutes)Section ADirections:In this section, you will hear 8 short conversations and 2 long conversations.

Early in the 1900s most American towns and cities had a Main Street. Main Street was always the 47 of a town. This street was lined on the both sides with many 48 businesses. Here, shoppers walked into stores to look at all sorts of merchandise: clothing, furniture, hardware, groceries. In addition, some shops offered 49 . There shops included drugstores, restaurants, shoe repair stores, and barber or hairdressing shops. But in the 1950s, a change began to 50 place. Too many automobiles had crowded into Main Street while too few parking places were 51 to shoppers. Because the streets were crowded, merchants began to look with interest at the open spaces outside the city limits. Open space is what their car driving customers 52 . And open space is what they got when the first shopping centre was built. Shopping centers, or rather malls, 53 as a collection of small new stores away from crowded city centers. Attracted by hundreds of free parking space, customers were drawn away from 54 areas to outlying malls. And the growing 55 of shopping centers led in turn to the building of bigger and better stocked stores. By the late 1970s, many shopping malls had almost developed into small cities themselves. In addition to providing the 56 of the stop shopping, malls were transformed into landscaped parks, with benches, fountains, and outdoor entertainment.［A］designed［F］convenience［K］cosmetics［B］take［G］services［L］started［C］heart［H］fame［M］downtown［D］needed［I］various［N］available［E］though［J］popularity［O］cheapnessSection BDirections:There are 2 passages in this section.

This system of learned behavior patterns characteristic of the members of a given society is constantly shaped by a set of dynamic variables: language, religion, values and attitudes, manners and customs, aesthetics, technology, education, and social institutions. To cope with this system, an international manager needs both factual and interpretive knowledge of culture. To some extent, the factual knowledge can be learned; its interpretation comes only through experience.The most complicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture—one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonald’s. In some cases, globalization is a fact of life; however, cultural differences are still far from converging.The other school proposes that companies must tailor business approaches to individual cultures. Setting up policies and procedures in each country has been compared to an organ transplant; the critical question centers around acceptance or rejection. The major challenge to the international manager is to make sure that rejection is not a result of cultural myopia or even blindness.Fortune examined the international performance of a dozen large companies that earn 20 percent or more of their revenue overseas. The internationally successful companies all share an important quality: patience. They have not rushed into situations but rather built their operations carefully by following the most basic business principles. These principles are to know your adversary, know your audience, and know your customer.57.According to the passage, which of the following is true?［A］All international managers can learn culture.［B］Business diversity is not necessary.［C］Views differ on how to treat culture in business world.［D］Most people do not know foreign culture well.58.According to the author, the model of Pepsi_________.［A］is in line with the theories that the business is business the world around［B］is different from the model of McDonald’s［C］shows the reverse of globalization［D］has converged cultural differences59.The two schools of thought____________.［A］both propose that companies should tailor business approaches to individual cultures［B］both advocate that different policies be set up in different countries［C］admit the existence of cultural diversity in business world［D］both A and B60.This article is supposed to be most useful for those____________.［A］who are interested in researching the topic of cultural diversity［B］who have connections to more than one type of culture［C］who want to travel abroad［D］who want to run business on International Scale61.According to Fortune, successful international companies________________.［A］earn 20 percent or more of their revenue overseas［B］all have the quality of patience［C］will follow the overseas local cultures［D］adopt the policy of internationalizationPassage TwoQuestions 62 to 66 are based on the following passage.There are people in Italy who can’t stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn or even frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it’s a game better suited to the 19th century, slow, quiet, and gentlemanly. These are the same people you may be one of them who love football because there’s the sport that glorifies “the hit”.By contrast, baseball seems abstract, cool, silent, still.On TV the game is fractured into a dozen perspectives, replays, close-ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space and time for involvement. The TV won’t do it for you.Take, for example, the third baseman. You sit behind the third base dugout and you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms or brings the glove to a point in front of him, takes a step right or left, backward or forward, perhaps he glances across the field to check his first baseman’s position. Suppose the pitch is a ball. “Nothing happened,” you say. “I could have had my eyes closed.”The skeptic and the innocent must play the game. And this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood. If football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.62.The passage is mainly concerned with_____________.［A］the different tastes of people for sports［B］the different characteristics of sports［C］the attraction of football［D］the attraction of baseball63.Those who don’t like baseball may complain that_______________.［A］it is only to the taste of the old［B］it involves fewer players than football［C］it is not exciting enough［D］it is pretentious and looks funny64.The author admits that____________.［A］baseball is too peaceful for the young［B］baseball may seem boring when watched on TV［C］football is more attracting than baseball［D］baseball is more interesting than football65.By stating “I could have had my eyes closed.” the author means (4th paragraph last sentence)_____________. ［A］the third baseman would rather sleep than play the game［B］even if the third baseman closed his eyes a moment ago, it could make no difference to the result［C］the third baseman is so good at baseball that he could finish the game with eyes closed all the time and do his work well［D］the consequence was so bad that he could not bear to see it66.We can safely conclude that the author__________________.［A］likes football［B］hates football［C］hates baseball［D］likes baseballPart ⅤCloze （15 minutes）Directions:There are 20 blanks in the following passage.

How did the critics like the new play? 67 an event takes place, newspapers are on the streets 68 the details. Wherever anything happens in the world, reports are on the spot to 69 the news. Newspapers have one basic 70 , to get the news as quickly as possible from its source, from those who make it to those who want to 71 it. Radio, telegraph, television,and 72 inventions brought competition for newspapers. So did the development of magazines and other means of communication. 73 , this competition merely spurred the newspapers on. They quickly made use of the newer and faster means of communication to improve the 74 and thus the efficiency of their own operations. Today more newspapers are 75 and read than ever before.

To put it in a metaphor, keeping a good mood is a foundation upon which our life is built.Keeping a good mood is important because it can help us solve various problems in life. The following two situations can enable us to clearly see how a positive attitude helps us cope with unpleasant things. Take English learning for example. In our effort to grasp English, mistakes are unavoidable. From one perspective mistakes are annoying, but a positive attitude can make us realize that only through making mistakes can a learner be expected to make progress. Sometimes one may come down with a serious cold, feeling depressed. But a change in attitude will enable us to look at the matter from a positive perspective. The illness may teach us the importance of health.As we can see, keeping a good mood can help us to deal with mistakes in the right way and find comfort in time of sorrow. Its importance cannot be denied.Part II Reading Comprehension(Skimming and Scanning)1. Y 通读全文后，即可发现本文描写了新奥尔良被“卡特利娜”飓风袭击后的景象，可知题干表述正确。
