Eachstatement contains information given in one of the paragraphs. Identify the paragraphfrom which the information is derived. You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking thecorresponding letter on Answer Sheet 2.The Secret to Raising Smart KidsA) I first began to investigate the basis of human motivation--and how people persevere aftersetbacks--as a psychology graduate student at Yale University in the 1960s. Animal experiments bypsychologists at the University of Pennsylvania had shown that after repeated failures, most animalsconclude that a situation is hopeless and beyond their control. After such an experience an animaloften remains passive even when it can effect change--a state they called learned helplessness.B) People can learn to be helpless, too. Why do some students give up when they encounter difficulty,whereas others who are no more skilled continue to strive and learn One answer, I soondiscovered, lay in people's beliefs about why they had failed.C) In particular, attributing poor performance to a lack of ability depresses motivation more than doesthe belief that lack of effort is to blame. When I told a group of school children who displayedhelpless behavior that a lack of effort led to their mistakes in math, they learned to keep tryingwhen the problems got tough. Another group of helpless children who were simply rewarded fortheir success on easier problems did not improvetheir ability to solve hard math problems. Theseexperiments indicated that a focus on effort can help resolve helplessness and generate success.D) Later, I developed a broader theory of what separates the two general classes of learners--helplessversus mastery-oriented.I realized these different types of students not only explain their failuresdifferently, but they also hold different "theories" of intelligence.The helpless ones believeintelligence is a fixed characteristic: you have only a certain amount, and that's that. I call this a"fixed mind-set (思维模式). " Mistakes crack their self-confidence because they attribute errors toa lack of ability, which they feel powerless to change. They avoid challenges because challengesmake mistakes more likely. The mastery-oriented children, on the other hand, think intelligence isnot fixed and can be developed through education and hard work. Such children believe challengesare energizing rather than intimidating (令人生畏); they offer opportunities to learn. Studentswith such a growth mind-set were destined (注定) for greater academic success and were quitelikely to outperform their counterparts.E) We validated these expectations in a study in which two other psychologists and I monitored 373students for two years during the transition to junior high school, when the work gets more difficultand the grading more strict, to determine how their mind-sets might affect their math grades. At thebeginning of seventh grade, we assessed the students' mind-sets by asking them to agree or disagreewith statementssuch as "Your intelligence is something very basic about you that you can't reallychange. " We then assessed their beliefs about other aspects of learning and looked to see whathappened to their grades.F) As predicted, the students with a growth mind-set felt that learning was a more important goal thangetting good grades. In addition, they held hard work in high regard. They understood that evengeniuses have to work hard. Confronted by a setback such as a disappointing test grade, studentswith a growth mind-set said they would study harder or try a different strategy. The students whoheld a fixed mind-set, however, were concerned about looking smart with less regard for learning.They had negative views of effort, believing that having to work hard was a sign of low ability.They thought that a person with talent or intelligence did not need to work hard to do well.Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that they wouldstudy less in the future, try never to take that subject again and consider cheating on future tests.G) Such different outlooks had a dramatic impact on performance. At the start of junior high, the mathachievement test scores of the students with a growth mind-set were comparable to those ofstudents who displayed a fixed mind-set. But as the work became more difficult, the students witha growth mind-set showed greater persistence. As a result, their math grades overtook those of theother students by the end of the first semester--and the gap between the two groups continued towiden during the two years we followed them.H) A fixed mind-set can also hinder communication and progress in the workplace and discourage orignore constructive criticism and advice. Research shows that managers who have a fixed mind-setare less likely to seek or welcome feedback from their employees than are managers with a growthmind-set.I) How do we transmit a growth mind-set to our children One way is by telling stories aboutachievements that result from hardwork. For instance, talking about mathematical geniuses whowere more or less born that way puts students in a fixed mind-set, but descriptions of greatmathematicians who fell in love with math and developed amazing skills produce a growth mind-set.J) In addition, parents and teachers can help children by providing explicit instruction regarding themind as a learning machine. I designed an eight-session workshop for 91 students whose mathgrades were declining in their first year of junior high.Forty-eight of the students receivedinstruction in study skills only, whereas the others attended a combination of study skills sessionsand classes in which they learned about the growth mind-set and how to apply it to schoolwork. Inthegrowth mind-set classes, students read and discussed an article entitled "You Can Grow YourBrain. " They were taught that the brain is like a muscle that gets stronger with use and thatlearning prompts the brain to grow new connections. From such instruction, many students beganto see themselves as agents of their own brain development. Despite being unaware that there weretwo types of instruction, teachers reported significant motivational changes in 27% of the childrenin the growth mind-set workshop as compared with only 9% of students in the control group.K) Research is converging (汇聚) on the conclusion that great accomplishment and even genius istypically the result of years of passion and dedication and not something that flows naturally from agift.36. The author's experiment shows that students with a fixed mind-set believe having to work hard is an indication of low ability.37. Focusing on effort is effective in helping children overcome frustration and achieve success.38. We can cultivate a growth mind-set in children by telling success stories that emphasize hard work and love of learning.39. Students' belief about the cause of their failure explains their attitude toward setbacks.40. In the author's experiment, students with a growth mind-set showed greater perseverance in solving difficult math problems.41. The author conducted an experiment to find out about the influence of students' mind-sets on math learning.42. After failing again and again, most animals give up hope.43. Informing students about the brain as a learning machine is a good strategy to enhance their motivation for learning.44. People with a fixed mind-set believe that one's intelligence is unchangeable.45. In the workplace, feedback may not be so welcome to managers with a fixed mind-set.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions orunfinished statements. For each of them there are four choices markedA.,B.,C. AndD . You should decide on the best choice and mark the corresponding letter on AnswerSheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage."Sugar, alcohol and tobacco," economist Adam Smith oncewrote," are commodities which arenowhere necessaries of life, which have become objects of almost universal consumption, and whichare, therefore, extremely popular subjects of taxation. "Two and a haft centuries on, most countries impose some sort of tax on alcohol and tobacco. Withsurging obesity levels putting increasing strain on public health systems, governments around the worldhave begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found afall in purchases of taxed drinks as well as a rise in sales of untaxed and healthier drinks. By contrast,a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims thatconsumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattierfare.The food industry has, in general, been firmly opposed to such direct government action.Nonetheless, the renewed focus on waistlines means that industry groups are under pressure todemonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of itsofferings. For example, some drink manufacturers have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount ofsugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however, somecompanies have been investing money in a more ambitious undertaking: learning how to adjust thefundamental make-up of the food they sell. For example, having salt on theoutside, but none on theinside, reduces the salt content without changing the taste.While reformulating recipes ( 配方) is one way to improve public health, it should be part of amulti-sided approach. The key is to remember that there is not just one solution. T o deal with obesity,a mixture of approaches--including reformulation, taxation and adjusting portion sizes--will beneeded. There is no silver bullet.46. What did Adam Smith say about sugar, alcohol and .tobaccoA. They were profitable to manufacture.B. They were in ever-increasing demand.C. They were subject to taxation almost everywhere.D. They were no longer considered necessities of life.47. Why have many countries started to consider taxing sugarA. They are under growing pressure to balance their national budgets.B. They find it ever harder to cope with sugar-induced health problems.C. The practice of taxing alcohol and tobacco has proved both popular and profitable.D. The sugar industry is overtaking alcohol and tobacco business in generating profits.48. What do we learn about Danish taxation on fat-rich foodsA. It did not work out as well as was expected.B. It gave rise to a lot of problems on the border.C. It could not succeed without German cooperation.D. It met with firm opposition from the food industry.49. What is the more recent effort by food companies tomake foods and drinks both healthy and tastyA. Replacing sugar or salt with alternative ingredients.B. Setting a limit on the amount of sugar or salt in their products.C. Investing in research to find ways to adapt to consumers' needs.D. Adjusting the physical composition of their products.50. What does the author mean by saying, at the end of the passage, "There is no silver bullet" ( Line 4, Para.7)A. There is no single easy quick solution to the problem.B. There is no hope of success without public cooperation.C. There is no hurry in finding ways to solve the obesity problem.D. There is noeffective way to reduce people's sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may have heard some of the fashion industry horror stories: models eating tissues or cottonballs to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds afterthey step off the runway.Excessively skinny models have been a point of controversy for decades, and two researchers saya model's body mass should be a workplace health and safety issue. In an editorial released Monday inthe American Journal of Public Health, Katherine Record and Bryn Austin made their case forgovernment regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16--low enough toindicate starvation by the World Health Organization's standard. And Record and Austin areworried notjust about the models themselves, but about the vast number of girls and women their images influence."Especially girls and teens," says Record. "Seventy percent of girls aged 10 to 18 report that theydefine perfect body image based on what they see in magazines. " That's especially worrying, she says,given that anorexia (厌食症) results in more deaths than does any other mental illness, according tothe National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lung disease in coalminers. Professional fashion models are particularly vulnerable to eating disorders resulting fromoccupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below 18.In April, France passed a law setting lower limits for a model's weight. Agents and fashion houseswho hire models with a BMI under 18 could pay $ 82,000 in fines and spend up to 6 months in jail.Regulating the fashion industry in the United States won't be easy, Record says. But with the new rulesin France, U.S. support could make a difference. "A designer can't survive without participating inParis Fashion Week", she says, adding," Our argument is that the same would be true of New YorkFashion Week. "51. What do Record and Austin say about fashion models' body massA. It has caused needless controversy.B. It is but a matter of personal taste.C. It is the focus of the modeling business.D. It affects models' health and safety.52. What are Record and Austin advocating in the MondayeditorialA. A change in the public's view of female beauty.B. Government legislation about models' weight.C. Elimination of forced weight loss by models.D. Prohibition of models eating non-food stuff.53. Why are Record and Austin especially worried about the low body mass index of modelsA. It contributes to many mental illnesses.B. It defines the future of the fashion industry.C. It has great influence on numerous girls and women.D. It keeps many otherwise qualified women off the runway.54. What do we learn about France's fashion industryA. It has difficulty hiring models.B. It has now a new law to follow.C. It allows girls under 18 on the runway.D. It has overtaken that of the United States.55. What does Record expect of New York Fashion WeekA. It will create a completely new set of rules.B. It will do better than Paris Fashion Week.C. It will differ from Paris Fashion Week.D. It will have models with a higher BMI.Part ⅣTranslation( 30 minutes )Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese intoEnglish.

A new study(26)that belief, questioning whether brains really can be distinguished by gender.In the study, Tel Aviv University researchers(27)for sex differences the entire human brain.And what did they find? Not much. Rather than offer evidence for (28)brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.Daphna Joel, who led the study, said her research found that while there are some gender-based(29), many different types of brain can’t always be distinguished by gender.While the “average” male and “average” fe male brains were(30)different, you couldn’t tell it by looking at individual brain scans. Only a small(31)of people had “all-male” or “all-female” characteristics.Larry Cahill, an American neuroscientist (神经科学家),said the study is an important addition to a growing body of research questioning(32)beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same,(33)of gender.“There’s a mountain of evidence(34)the importance of sex influences at a ll levels of brain function,” he told The Seattle Times.If anything, he said, the study(35) that gender plays a very important role in the brain “even when we are not clear exactly how.”Section BDirections: In this section, you are going to read a passage with ten statements attached to it.

So it isn’t surprising that you’ll find plen ty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam”a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though a t that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipme nt. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaki ng a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for thi ngs to steal. However,he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessaryequipment and skill.37. Interfering with a wireless security system is similar to interferingwith a conversation.38. A burglar has to continuously jam the wireless security device to avoidtriggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidentalradio interference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarmonce something wrong is detected.43. Different measures should be taken to protect one’s home fromburglary in addition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hat e it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other b ar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passage?A) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tipping?A) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the author?A) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a survey?A) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passage?A) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers.Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’ consumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into English.You should write your answer on Answer Sheet 2.在中国文化中,红色通常象征着好运、长寿和幸福,在春节和其他喜庆场合,红色到处可见。

Animal experiments bypsychologists at the University of Pennsylvaniahad shown that after repeated failures, most animalsconclude that a situationis hopeless and beyond their control. After such an experience an animaloftenremains passive even when it can effect change--a state they called learned helplessness.B) People can learn to be helpless, too. Why do some students give up when theyencounter difficulty,whereas others who are no more skilled continue to striveand learn? One answer, I soondiscovered, lay in people's beliefs about why theyhad failed.C) In particular, attributing poor performance to a lack of ability depressesmotivation more than doesthe belief that lack of effort is to blame. When I told a group of school children who displayedhelpless behavior that a lack ofeffort led to their mistakes in math, they learned to keep tryingwhen the problems got tough. Another group of helpless children who were simply rewardedfortheir success on easier problems did not improve their ability to solve hardmath problems. Theseexperiments indicated that a focus on effort can help resolve helplessness and generate success.D) Later, I developed a broader theory of what separates the two general classes of learners--helplessversus mastery-oriented. I realized these different types of students not only explain their failuresdifferently, but they also hold different "theories" of intelligence.The helpless ones believeintelligence is a fixed characteristic: you have only a certain amount,and that's that. I call this a"fixed mind-set (思维模式). " Mistakes crack their self-confidence because they attribute errors toa lack of ability, whichthey feel powerless to change. They avoid challenges because challengesmake mistakes more likely. The mastery-oriented children, on the other hand, thinkintelligence isnot fixed and can be developed through education and hard work.Such children believe challengesare energizing rather than intimidating (令人生畏); they offer opportunities to learn. Studentswith such a growth mind-set were destined (注定) for greater academic success and were quitelikely to outperform their counterparts.E) We validated these expectations in a study in which two other psychologistsand I monitored 373students for two years during the transition to junior highschool, when the work gets more difficultand the grading more strict, to determine how their mind-sets might affect their math grades. At thebeginningof seventh grade, we assessed the students' mind-sets by asking them to agreeor disagreewith statements such as "Your intelligence is something very basicabout you that you can't reallychange. " We then assessed their beliefs aboutother aspects of learning and looked to see whathappened to their grades.F) As predicted, the students with a growth mind-set felt that learning was amore important goal thangetting good grades. In addition, they held hard workin high regard. They understood that evengeniuses have to work hard. Confrontedby a setback such as a disappointing test grade, studentswith a growth mind-setsaid they would study harder or try a different strategy. The students whohelda fixed mind-set, however, were concerned about looking smart with less regardfor learning.They had negative views of effort, believing that having to workhard was a sign of low ability.They thought that a person with talent or intelligence did not need to work hard to do well.Attributing a bad grade totheir own lack of ability, those with a fixed mind-set said that they wouldstudy less in the future, try never to take that subject again and consider cheating on future tests.G) Such different outlooks had a dramatic impact on performance. At the startof junior high, the mathachievement test scores of the students with a growthmind-set were comparable to those ofstudents who displayed a fixed mind-set. But as the work became more difficult, the students witha growth mind-set showed greater persistence. As a result, their math grades overtook those of theother students by the end of the first semester--and the gap between the twogroups continued towiden during the two years we followed them.H) A fixed mind-set can also hinder communication and progress in the workplaceand discourage orignore constructive criticism and advice. Research shows thatmanagers who have a fixed mind-setare less likely to seek or welcome feedbackfrom their employees than are managers with a growthmind-set.I) How do we transmit a growth mind-set to our children? One way is by tellingstories aboutachievements that result from hard work. For instance, talking about mathematical geniuses whowere more or less born that way puts students ina fixed mind-set, but descriptions of greatmathematicians who fell in love withmath and developed amazing skills produce a growth mind-set.J) In addition, parents and teachers can help children by providing explicit instruction regarding themind as a learning machine. I designed an eight-session workshop for 91 students whose mathgrades were declining in their firstyear of junior high.Forty-eight of the students receivedinstruction in study skills only, whereas the others attended a combination of study skills sessionsand classes in which they learned about the growth mind-set and how toapply it to schoolwork. Inthe growth mind-set classes, students read and discussed an article entitled "You Can Grow YourBrain. " They were taught thatthe brain is like a muscle that gets stronger with use and thatlearning promptsthe brain to grow new connections. From such instruction, many students begantosee themselves as agents of their own brain development. Despite being unawarethat there weretwo types of instruction, teachers reported significant motivational changes in 27% of the childrenin the growth mind-set workshop ascompared with only 9% of students in the control group.K) Research is converging (汇聚) on the conclusion that great accomplishmentand even genius istypically the result of years of passion and dedication andnot something that flows naturally from agift.36. The author's experiment shows that students with a fixed mind-set believehaving to work hard is an indication of low ability.37. Focusing on effort is effective in helping children overcome frustration and achieve success.38. We can cultivate a growth mind-set in children by telling success storiesthat emphasize hard work and love of learning.39. Students' belief about the cause of their failure explains their attitudetoward setbacks.40. In the author's experiment, students with a growth mind-set showed greaterperseverance in solving difficult math problems.41. The author conducted an experiment to find out about the influence of students' mind-sets on math learning.42. After failing again and again, most animals give up hope.43. Informing students about the brain as a learning machine is a good strategyto enhance their motivation for learning.44. People with a fixed mind-set believe that one's intelligence is unchangeable.45. In the workplace, feedback may not be so welcome to managers with a fixedmind-set.Section CDirections: There are 2 passages in this section. Each passage is followed bysome questions orunfinished statements. For each of them there are four choicesmarked A., B., C. AndD . You should decide on the best choice and mark the corresponding letter on AnswerSheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage."Sugar, alcohol and tobacco," economist Adam Smith once wrote," are commoditieswhich arenowhere necessaries of life, which have become objects of almost universal consumption, and whichare, therefore, extremely popular subjects of taxation. "Two and a haft centuries on, most countries impose some sort of tax on alcoholand tobacco. Withsurging obesity levels putting increasing strain on public health systems, governments around the worldhave begun to toy with the idea oftaxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico'staxation found afall in purchases of taxed drinks as well as a rise in sales ofuntaxed and healthier drinks. By contrast,a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims thatconsumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattierfare.The food industry has, in general, been firmly opposed to such direct government action.Nonetheless, the renewed focus on waistlines means that industry groups are under pressure todemonstrate their products are healthy aswell as tasty.Over the past three decades, the industry has made some efforts to improve thequality of itsofferings. For example, some drink manufacturers have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount ofsugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however, somecompanies have been investing money in a more ambitious undertaking: learning how to adjust thefundamental make-up of the food they sell. For example, having salt on theoutside, but none on theinside, reduces the salt content without changing thetaste.While reformulating recipes ( 配方) is one way to improve public health, it should be part of amulti-sided approach. The key is to remember that there isnot just one solution. To deal with obesity,a mixture of approaches--includingreformulation, taxation and adjusting portion sizes--will beneeded. There is nosilver bullet.46. What did Adam Smith say about sugar, alcohol and .tobacco?A. They were profitable to manufacture.B. They were in ever-increasing demand.C. They were subject to taxation almost everywhere.D. They were no longer considered necessities of life.47. Why have many countries started to consider taxing sugar?A. They are under growing pressure to balance their national budgets.B. They find it ever harder to cope with sugar-induced health problems.C. The practice of taxing alcohol and tobacco has proved both popular and profitable.D. The sugar industry is overtaking alcohol and tobacco business in generatingprofits.48. What do we learn about Danish taxation on fat-rich foods?A. It did not work out as well as was expected.B. It gave rise to a lot of problems on the border.C. It could not succeed without German cooperation.D. It met with firm opposition from the food industry.49. What is the more recent effort by food companies to make foods and drinksboth healthy and tasty?A. Replacing sugar or salt with alternative ingredients.B. Setting a limit on the amount of sugar or salt in their products.C. Investing in research to find ways to adapt to consumers' needs.D. Adjusting the physical composition of their products.50. What does the author mean by saying, at the end of the passage, "There isno silver bullet" ( Line 4, Para.7)?A. There is no single easy quick solution to the problem.B. There is no hope of success without public cooperation.C. There is no hurry in finding ways to solve the obesity problem.D. There isno effective way to reduce people's sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may have heard some of the fashion industry horror stories: models eatingtissues or cottonballs to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds afterthey step off the runway.Excessively skinny models have been a point of controversy for decades, and tworesearchers saya model's body mass should be a workplace health and safety issue. In an editorial released Monday inthe American Journal of Public Health,Katherine Record and Bryn Austin made their case forgovernment regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16--low enough toindicate starvation by the World Health Organization's standard.And Record and Austin are worried notjust about the models themselves, but about the vast number of girls and women their images influence."Especially girls and teens," says Record. "Seventy percent of girls aged 10 to18 report that theydefine perfect body image based on what they see in magazines. " That's especially worrying, she says,given that anorexia (厌食症) results in more deaths than does any other mental illness, according tothe National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lungdisease in coalminers. Professional fashion models are particularly vulnerableto eating disorders resulting fromoccupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below18.In April, France passed a law setting lower limits for a model's weight. Agentsand fashion houseswho hire models with a BMI under 18 could pay $ 82,000 in fines and spend up to 6 months in jail.Regulating the fashion industry in theUnited States won't be easy, Record says. But with the new rulesin France, U.S.support could make a difference. "A designer can't survive without participating inParis Fashion Week", she says, adding," Our argument is that the same would be true of New YorkFashion Week. "51. What do Record and Austin say about fashion models' body mass?A. It has caused needless controversy.B. It is but a matter of personal taste.C. It is the focus of the modeling business.D. It affects models' health and safety.52. What are Record and Austin advocating in the Monday editorial?A. A change in the public's view of female beauty.B. Government legislation about models' weight.C. Elimination of forced weight loss by models.D. Prohibition of models eating non-food stuff.53. Why are Record and Austin especially worried about the low body mass indexof models?A. It contributes to many mental illnesses.B. It defines the future of the fashion industry.C. It has great influence on numerous girls and women.D. It keeps many otherwise qualified women off the runway.54. What do we learn about France's fashion industry?A. It has difficulty hiring models.B.

2016年12月英语四级真题及答案卷二英语四级考试采取“多题多卷”模式,试题顺序不统一,请依据试题进行核对!作文题目:For this part, you are allowed 30 minutes to write an essay. Suppose you have two options upon graduation: one is to take a job in a company and the other to go to a graduate school. You are to make a choice between the two. Write an essay to explain the reasons for your choice. You should write at least 120 words but no more than 180 words.参考范文:Upon graduation, virtually all college students will confront the problem of the career choice,which is truly a tough choice. Students' opinions differ greatly on this issue. Some hold that priority should be given to take a job, but others take the attitude that going to a graduate school is the most critical factor influencing their future career choices.As to myself, I prefer the latter view. A higher educational background exerts a tremendous fascination on a great number of people, with no exception to me. This phenomenon that the graduates have difficulties in finding job after their graduation can easily be found anywhere in our daily life, especially on campus. On the one hand, with the improved high education of Chinese college students which directly brought the result that there are more and more graduates every year. On the contrary, job vac ancies don’t increase that fast. More people, less food, which is the exact description of the hard condition. On the other hand, more and more people go on to pursue their master and doctor degree; more and more Chinese oversea students come back to China to hunt better working chances. It is sure that the competition is more and more fierce.Therefore, it is high time that we took effective measures to improve our own competitiveness. That is the secret of success in the future employment market after our graduation.Part ⅢReading Section A(卷二)The ocean is heating up.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it isn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what abouttheir wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam”a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separatingincidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipment. However, we also verified that SimpliSafe’santi-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documentedcases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grabattack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit.A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of aless-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessaryequipment and skill.37. Interfering with a wireless security system is similar to interfering witha conversation.38. A burglar has to continuously jam the wireless security device toavoid triggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidentalradio interference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarm oncesomething wrong is detected.43. Different measures should be taken to protect one’s home fromburglary in addition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are thatgreat. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers ofhumanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passage?A) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tipping?A) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the author?A) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a survey?A) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passage?A) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers. Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’consumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partlybecause oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy. Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into English.You should write your answer on Answer Sheet 2.在中国文化中,红色通常象征着好运、长寿和幸福,在春节和其他喜庆场合,红色到处可见。

Students' opinions differ greatly on this issue. Some hold that priority should be given to take a job, but others take the attitude that going to a graduate school is the most critical factor influencing their future careerchoices.As to myself, I prefer the latter view. A higher educational backgroundexerts a tremendous fascination on a great number of people, with noexception to me. This phenomenon t hat the graduates have difficulties in finding job after their graduation can easily be found anywhere in ourdaily life, especially on campus. On t he one hand, with the improved high education of Chinese college students whichdirectly brought the resultthat there are more and more graduates every year. On the contrary, jobvacancies don’t increase that fast. More people, less food, which is the exact description of the hard condition. On the other hand, more and more people go on to pursue their master and doctor degree; more and moreChinese oversea students come b ack to China to hunt better working chances. It is sure that the competition is more and more fierce.Therefore, it is high time that we took effective measures to improve our own competitiveness. That is the secret of success in the futureemployment market after our graduation.Part Ⅲ Reading Section A(卷二)The ocean is heating up.

college graduates, some ambitious students have tried their hands at launching their own businesses. over the years,there have been many successful cases of student entrepreneurship and such attempts should be encouragedand promoted by both the universities and the society at large. what’smore ,college students who start businesses are pioneers,among whom will be born china’s future business

Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it isn’t surprising that you’ll find plen ty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. Wh en the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipment. However, we also verified that SimpliSafe’santi-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical detail s of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or openeddoor would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for thi ngs to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessary equipmentand skill.37. Interfering with a wireless security system is similar to interfering with aconversation.38. A burglar has to continuously jam the wireless security device to avoid triggeringthe alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidental radiointerference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarm once somethingwrong is detected.43. Diff erent measures should be taken to protect one’s home from burglary inaddition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequ ency by Internet search.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hat e it because it’s an obligation disgu ised as an option. I hate it for thepost-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a f ull 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other b ar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passage?A) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tipping?A) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the author?A) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a survey?A) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passage?A) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers.Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’ consumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “M any oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasolinesubsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why have n’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into English.You should write your answer on Answer Sheet 2.在中国文化中,红色通常象征着好运、长寿和幸福,在春节和其他喜庆场合,红色到处可见。

Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Many men and women have long bought into the idea that there are “male” and “female” brains, believing that explains just about every difference between the sexes.A new study(26)that belief, questioning whether brains really can be distinguished by gender.In the study, Tel Aviv University researchers(27)for sex differences the entire human brain.And what did they find? Not much. Rather than offer evidence for(28)brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.Daphna Joel, who led the study, said her research found that while there are some gender-based(29), many different types of brain can’t always be distinguished by gender.While the “average” male and “average” female brains were(30)different, you couldn’t tell it by lo oking at individual brain scans. Only a small(31)of people had “all-male” or “all-female” characteristics.Larry Cahill, an American neuroscientist (神经科学家),said the study is an important addition to a growing body of research questioning(32)beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same,(33)of gender.“There’s a mountain of evidence(34)the importance of sex influences at all levels of brain function,” he told The Seattle Times.If anything, he said, the study(35)that gender plays a very important role in the brain “even when we are not clear exactly how.”Section BDirections: In this section, you are going to read a passage with ten statements attached to it.

Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasolinesubsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into English.You should write your answer on Answer Sheet 2.在中国文化中,红色通常象征着好运、长寿和幸福,在春节和其他喜庆场合,红色到处可见。

You are requiredto select one word for each blank from a list of choices given in a wordbank following the passage. Read the passage through carefully beforemaking your choices. Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet 2 witha single line through the centre. You may not use any of the words in thebank more than onceQuestions 36 to 45 are based on the following passage.Scholars of the information society are divided over whether social inequalitydecreases or increases in an information-based society. However, they generallyagree with the idea that inequality in the information society is __36__ different from that of an industrial society. As informatization progresses in society, the cause and structural nature ofsocial inequality changes as well.It seems that the information society__37__ the quantity of information availableto the members of a society by revolutionizing the ways of using and exchanginginformation.But such a view is a __38__ analysis based on the quantity of information supplied by various forms of the mass media.

I have visited some of the newer supposedly "effective" schools, where children shout slogans in order to leam self-control or muststand behind their desk when they can't sit still.C)A look at what goes on in most classrooms these days makes it abundantly clearthat when people think about education, they are not thinking about what it feelslike to be a child,or what makes childhood an important and valuable stage of life in its own right.D) I'm a mother of three, a teacher,and a developmental psychologist.So I've watched a lot of children— talking, playing, arguing, eating, studying, and being young.Here's what I've come to understand.The thing that sets children apart from adults is not their ignorance,nor their lack of skills. It's their enormous capacity for joy.Think of a 3-year-old lost in the pleasures of finding out what he can and cannot sink in the bathtub, a 5-year-old beside herself with the thrill of putting together strings of nonsensical words with her best friends, or an 11-year-old completelyabsorbed in a fascinating comic strip. A child's ability to become deeply absorbed in something,and derive intense pleasure from that absorption,is something adults spend the rest of their lives trying to return to.E) A friend told me the following story.One day, when he went to get his 7-year-old son from soccer practice,his kid greeted him with a downcast face and a sad voice. The coach had criticized him for not focusing on his soccer drills. The little boywalked out of the school with his head and shoulders hanging down. He seemed wrapped in sadness.But just before he reached the car door,he suddenly stopped,crouching (蹲伏)down to peer at something on the sidewalk.His face went down lower and lower, and then, with complete joy he called out, "Dad. Come here. This is the strangestbug I've ever seen. It has, like, a million legs. Look at this. It's amazing. " Helooked up at his father, his features overflowing with energy and delight. "Can'twe stay here for just a minute?I want to find out what he does with all those legs. This is the coolest ever. "F) The traditional view of such moments is that they constitute a charming butirrelevant byproduct of youth— something to be pushed aside to make room for more important qualities, like perseverance (坚持不懈 ), obligation, and practicality.Yet moments like this one are just the kind of intense absoiption and pleasure adults spend the rest of their lives seeking. Human lives are governed by the desire toexperience joy.Becoming educated should not require giving up joy but rather lead to finding joy in new kinds of things:reading novels instead of playing with small figures, conductingexperiments instead of sinking cups in the bathtub, and debating serious issuesrather than stringing together nonsense words,for example.In some cases,schools should help children find new, more grown-up ways of doing the same things that are constant sources of joy: making art, making friends, making decisions.G) Building on a child's ability to feel joy,rather than pushing it aside,wouldn't be that hard. It would just require a shift in the education world's mindset (思维模式 ). Instead of trying to get children to work hard, why not focus on gettingthem to take pleasure in meaningful, productive activity, like making things,working with others, exploring ideas, and solving problems? These focuses are notso different from the things in which they delight.H) Before you brush this argument aside as rubbish,or think of joy as an unaffordable luxury in a nation where there is awful poverty,low academic achievement,and high dropout rates, think again. The more horrible the school circumstances, the moreimportant pleasure is to achieving any educational success.I) Many of the assignments and rules teachers come up with, often because they arepressured by their administrators,treat pleasure and joy as the enemies of competence and responsibility. The assumption is that children shouldn't chat inthe classroom because it hinders hard work; instead, they should leain to delaygratification( 快乐 ) so that they can pursue abstract goals,like going to college.J) Not only is this a boring and awful way to treat children, it makes no senseeducationally. Decades of research have shown that in order to acquire skills andreal knowledge in school, kids need to want to learn.You can force a child to stay in his or her seat,fill out a worksheet,or practice division.But you can't force the child to think carefully,er\joy books,digest complex information,or develop a taste for learning.To make that happen, you have to help the child find pleasure inlearning—to see school as a source of joy.K)Adults tend to talk about learning as if it were medicine; unpleasant, butnecessary and good for you. Why not instead think of learning as if it were food— something so valuable to humans that they have evolved to experience it asa pleasure?L) Joy should not be trained out of children or left for after-school programs. The more difficult a child's life circumstances,the more important it is for that child to find joy in his or her classroom. "Pleasure" is not a dirty word. And it doesn't run counter to the goals of public education. It is, in fact, the precondition.46.It will not be difficult to make learning a source of joy if educators changetheir way of thinking.47.What distinguishes children from adults is their strong ability to derive joyfrom what they are doing.48.Children in America are being treated with shocking cruelty.49.It is human nature to seek joy in life.50.Grown-ups are likely to think that learning to children is what medicine isto patients.51.Bad school conditions make it all the more important to turn learning into ajoyful experience.52.Adults do not consider children's feelings when it comes to education.53. Administrators seem to believe that only hard work will lead children to theireducational goals.54.In the so-called "effective" schools, children are taught self-controlunder a set of strict rules.55. To make learning effective,educators have to ensure that children want to leam.Passage OneQuestions 56 to 60 are based on the following passage.When it's five o'clock, people leave their office. The length of the workday, formany workers,is defined by time.They leave when the clock tells them they're done.These days,the time is everywhere-,not just on clocks or watches,but on cell-phones and computers. That may be a bad thing, particularly at work. New research showsthat clock-based work schedules hinder morale (士气 ) and creativity.Clock-timers organize their day by blocks of minutes and hours. For example: ameeting from9 a.m. to10 a. m. ,research from 10 a.m. to noon,etc. On the other hand, task-timers have a list of things they want to accomplish.They work down the list, each task starts when the previous task is completed. It is said that all ofus employ a mix of both these types of planning.What, then, are the effects of thinking about time in these different ways? Doesone make us more productive? Better at the tasks at hand? Happier? In experimentsconducted by Tamar Avnet and Anne-Laure Sellier, they had participants organizedifferent activities—from project planning,holiday shopping,to yoga— by time or to-do list to measure how they performed under "clock time" vs "task time. " Theyfound clock timers to be more efficient but less happy because they felt littlecontrol Over their lives. Task timers are happier and more creative, but lessproductive.They tend to enjoy the moment when something good is happening, and seize opportunities that come up.under-supported in business culture. Smart companies, they believe, will try to bake more task-based planning into their strategies.This might be a small change to the way we view work and the office, but theresearchers argue that it challenges a widespread characteristic of the economy:work organized by clock time. While most people will still probably need, and be,to some extent, clock-timers, task-based timing should be used when performing ajob that requires more creativity. It'll make those tasks easier, and the task-doers will be happier.56.What does the author think of time displayed everywhere?A) It makes everybody time-conscious.B) It is a convenience for work and life.C) It may have a negative effect on creative work.D) It clearly indicates the fast pace of modem life.57.How do people usually go about their work according to the author?A) They combine clock-based and task-based planning.B) They give priority to the most urgent task on hand.C) They set a time limit for each specific task.D) They accomplish their tasks one by one.58.What did Tamar Avnet and Anne-Laure Sellier find in their experiments aboutclock-timers?A)They seize opportunities as they come up.B)They always get their work done in time.C)They have more control over their lives.D)They tend to be more productive.59.What do the researchers say about today's business culture?A) It does not support the strategies adopted by smart companies.B) It does not attach enough importance to task-based practice.C)It places more emphasis on work efficiency than on workers' lives.D)It aims to bring employees' potential and creativity into full play.60. What do the researchers suggest?A)Task-based timing is preferred for doing creative work.B)It is important to keep a balance between work and life.C)Performing creative jobs tends to make workers happier.D)A scientific standard should be adopted in job evaluation.Passage TwoQuestions 61 to 65 are based on the following passage.Martha Stewart was charged, tried and convicted of a crime in 2004. As she nearedthe end of her prison sentence, a well-known columnist wrote that she was " payingher dues," and that " there is simply no reason for anyone to attempt to deny herright to start anew. "Surely, the American ideal of second chances should not be reserved only for therich and powerful. Unfortunately,many federal and state laws impose post-conviction restrictions on a shockingly large number of Americans, who are prevented from ever fully paying their debt to society.At least 65 million people in the United States have a criminal record. This canresult in severe penalties that continue long after punishment is completed.Many of these penalties are imposed regardless of the seriousness of theoffense or the person's individual circumstances. Laws can restrict or ban voting,access to public housing, and professional and business licensing. They canaffect a person's ability to get a job and qualification for benefits.In all,more than45,000 laws and rules serve to exclude vast numbers of people from fully participating in American life.Some laws make sense. No one advocates letting someone convicted of pedophilia(恋童癖 ) work in a school. But too often collateral (附随的 ) consequences bear no relation to public safety.Should a womanwho possessed a small amount of drugs years ago be permanently unable to be licensed as a nurse?These laws are also counterproductive, since they make it harder for people withcriminal records to find housing or land a job, two key factors that reducebacksliding.A recent report makes several recommendations, including the abolition of mostpost-conviction penalties, except for those specifically needed to protect publicsafety. Where the penalties are not a must, they should be imposed only if the facts of a case support it.The point is not to excuse or forget the crime. Rather, it is to recognize that inAmerica's vast criminal justice system, second chances are crucial. It is in no one's interest to keep a large segment of the population on the margins of society.注意:此部分试题请在答题卡 2 上作答。

You may not use any of the words in the bank more than once.Many men and women have long bought into the idea that there are “male” and “female” brains, believing that explains just about every difference between the sexes.A new study 26 that belief, questioning whether brains really can be distinguished by gender.In the study, Tel Aviv University researchers 27 for sex differences the entire human brain.And what did they find? Not much. Rather than offer evidence for 28 brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.Daphna Joel, who led the study, said her research found that while there are some gender-based 29 , many different types of brain can’t always be distinguished by gender.While the “average” male and “average” female b rains were 30 different, you couldn’t tell it by looking at individual brain scans. Only a small 31 of people had “all-male” or “all-female” characteristics.Larry Cahill, an American neuroscientist (神经科学家),said the study is an importantaddition to a growing body of research questioning 32 beliefs about gender and brain function.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived.You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it isn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors,motion, and more. If they detect something wrong while the system is armed,they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’ssay you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling . They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipment. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act,sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving,and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However,he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessary equipment and skill.37. Interfering with a wireless security system is similar to interfering with a conversation.38. A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidental radio interference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.43. Different measures should be taken to protect one’s home from burglary inaddition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants withvoluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passage?A) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tipping?A) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the author?A) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a survey?A) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passage?A) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers.Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat upthe world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’consumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the U.S. at least, are actin g cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge mightsuggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minted to translate a passage from Chinese into English.

店铺为大家整理了英语四级真题参考答案,供大家参考!第一套英语四级真题参考答案Part Ⅰ WritingFinding A Job FirstCollege students’options upon graduation vary from person to person. Some students choose to hunt for a job while others prefer to start their own businesses. As for me, I would rather find a job first.The reasons for my decision are as follows. For one thing, it is much easier for me to find a job compared with starting a business which demands fund, experience, and the market. As a green hand who has just graduated from college, it’s totally beyond my ability to handle such a complex situation. For another, working for others could develop my personalities such as perseverance and stress tolerance, which can help me become more prepared and qualified if I would like to start my own business.To conclude, chances always favor those who are prepared. And I don’t think a person could really “build up from nothing”. As a result, I will find a job first after graduation.Part Ⅱ Listening ComprehensionSection A1 A) It was dangerous to live in.2 B) A storm.3 B) They were trapped in an underground elevator.4 C) They sent supplies to keep the miners warm.5 D) Close some of its post offices.6 C) Stopping mail delivery on Saturdays.7 A) Many post office staff will lose their jobs.Section B8 D) He will lose part of his pay.9 B) He is a trustworthy guy.10 D) She is better at handling such matters.11 C) He is always trying to stir up trouble.12 D) Reserved.13 A) They stay quiet.14 C) She was never invited to a colleague’s home.15 B) Houses provide more privacy.Section C16 D) They will automatically be given hiring priority.17 C) Visit the school careers service.18 B) Supervising study spaces to ensure a quiet atmosphere.19 C) It may be sold at a higher price.20 A) It is healthier than green tea.21 D) It does not have a stable market.22 B) They prefer unique objects of high quality.23 B) They could only try to create at night.24 A) Make wise choices.25 A) To boost the local economy.Part Ⅲ Reading ComprehensionSection A26 K) rarely27 O) tortured28 J) minimal29 D) determine30 G) inadequate31 B) creates32 E) direction33 M) strengthen34 L) shelters35 C) criticallySection B36 C) It might mean monitoring employee productivity on a digital leaderboard and offering prizes to the winners, or giving employees digital badges or stars for completing certain activities.37 J) Gamification is “not a magic bullet,” Werbach warns.38 G) ]Some people, Werbach says, are motivated by competition.39 D) The concept of gamification is not entirely new, Werbach says.40 K) Still, gamification only stands to become more popular, he says, “as more and more people come into the workforce who are familiar with the structures and expressions of digital games.”41 E) But the word “gamification” and the widespread, conscious application of the concept only began in earnest about five years ago, Werbach says.42 B) Increasingly, companies are tapping into these desires directly through what has come to be known as “gamification”: essentially, turning work into a game.43 H) Gamification does not have to be digital. Monica Cornetti runs a company that gamifies employee trainings.44 F) A number of companies have sprung up—GamEffective, Bunchball and Badgeville, to name a few—in recent yearsoffering gamification platforms for businesses.45 I) Some people do not take naturally to gamified work environments, Cornetti says.Section C46 C) They are over-burdened with administrative staff.47 A) Good classroom teachers.48 D) They are much bigger than is desirable.49 A) It requires talent and practice.50 B) Hiring more classroom teachers and allowing them to teach in their own way.51 D) It may be a pleasant way for kids to reduce their food intake.52 D) Most kids and adults would choose a smaller meal that came with a non-food item.53 B) Adults chose the smaller portion on the mere promise of a future award.54 A) The emotional component of the prizes is at work.55 D) More studies are needed to find out the impact of emotion on behavior.Part Ⅳ TranslationThe color of red in Chinese culture usually symbolizes good luck,longevity, and happiness. Red can be found everywhere during Chinese Spring Festival and other joyous occasions. Cashes are often put in red envelopes and sent to family members or close friends as gifts. The popularity of red in China can also be attributed to the fact that people associate it with the Chinese Revolution and the Communist Party. However, red does not signify good luck and joy all the time in that the name of the dead used to be written in red. Thus it is regarded as an offense to write the names of Chinese people in red ink.。

2016年12月大学英语四级考试真题及答案

2016年12月大学英语四级考试真题(第一套)Part I Writing (30 minutes) (请于正式开考后半小时完成该部分,之后将进行听力考试)Directions: For this part, you are allowed 30 minutes to write an essay. Suppose you have two options upon graduation: one is to take a job in a company and the other to go to a graduate school. You are to make a choice between the two. Write an essay to explain the reasons for your choice. You should write at least 120 words but no more than 180 words.Much controversy has been aroused about whether the students should find a job or start their own business after graduation. Taking a look around, we can find that some graduates bustle around job markets, while others choose to run a shop on TMall. However, I prefer the former choice.From my perspective, there are good reasons to find a job in the first several years after their graduation. First and foremost, if a graduate intends to accumulate working experience and learn from the seniors, it is advisable for him to find a job. It is an undeniable fact that the theoretical knowledge will provide the graduates with the ability to consider things comprehensively, however, only under the integration with practice can the rigid knowledge be useful for their future development. Inevitably, doing something small is the premise of undertaking something great. Take Jack Ma, the founder of Alibaba and taobao, for example. He also finds some jobs before establishing his own career, laying a solid foundation for his later success.Consequently, it is of great necessity to find a job after graduation. I firmly believe that it will continue to bring about more returns to our life and future.Part II Listening Comprehension (25 minutes)Section ADirections: In this section, you will hear three news reports.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose aparagraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?A)Any product that promises to protect your home deserves careful examination. So it isn't surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.B)The most likely type of burglary(入室盗窃)by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2013. The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.C)One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar(入室盗贼)might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?D)Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.E)Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimalGoogling. They will, however, need to know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort of forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.F)Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editors’ Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert (推送警报). From there, it’s up to you to sound the alarm manually.G)SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measure to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it is possible with the right equipment. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not it detected them.H) We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of a successful jam attack since the company began offering wireless security sensors in the 1980s.I)Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?J) Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you're away, so the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does not have access to.K) At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36.It is possible for burglars to make jamming attacks with the necessary equipment and skill.【答案】I37.Interfering with a wireless security system is similar to interfering witha conversation.【答案】D38.A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.【答案】J39.SimpliSafe provides devices that are able to distinguish incidental radio interference from targeted jamming attacks.【答案】F40.Only a very small proportion of burglaries are committed by technical means.【答案】B41.It is difficult to crack SimpliSafe as its system keeps changing.【答案】H42.Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.【答案】C43.Different measures should be taken to protect one’s home from burglary in addition to the wireless security system.【答案】K44.SimpliSafe’s device can send a warning to the house owner’s cellphone.【答案】G45.Burglars can easily get a security device’s frequency by Internet search.【答案】ESection CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B) , C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living, I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. ButI can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more up-front for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.46.What can we learn about Bill Perry from the passage?A)He runs a pub that serves excellent beer.B)He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.【答案】B47.What is the main reason why the author hates tipping?A)It sets a bad example for other industries.B)It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.【答案】C48.Why do many people love tipping according to the author?A)They help improve the quality of the restaurants they dine in.B)They believe waiters deserve such rewards for good service.C)They want to preserve a wonderful tradition of the industry.D)They can have some say in how much their servers earn.【答案】D49.What have some waiters come to realize according to a survey?A)Service quality has little effect on tip size.B)It is in human nature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather than the employees.【答案】A50.What does the author argue for in the passage?A)Restaurants should calculate the tips for customers.B)Customers should pay more tips to help improve service.C)Waiters deserve better than just relying on tips for a living.D)Waiters should be paid by employers instead of customers.【答案】DPassage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India. But doesn’t the extra money in the pockets of those countries, consumers mean an equal loss in oil-producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies (补贴)for their consumers.”But not all oil producers have big reserves. In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil- producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the prices drop account for a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51.What does the author mainly discuss in the passage?A)The reasons behind the plunge of oil prices.B)Possible ways to stimulate the global economy.C)The impact of cheap oil on global economic growth.D)The effect of falling oil prices on consumer spending.【答案】C52.Why do some experts believe cheap oil will stimulate the global economy?A)Manufacturers can produce consumer goods at a much lower cost.B)Lower oil prices have always given a big boost to the global economy.C)Oil prices may rise or fall but economic laws are not subject to change.D)Consumers will spend their savings from cheap oil on other commodities.【答案】D53.What happens in many oil-exporting countries when oil prices go down?A)They suspend import of necessities from overseas.B)They reduce production drastically to boost oil prices.C)They use their money reserves to back up consumption.D)They try to stop their economy from going into free-fall.【答案】C54.How does Carl Weinberg view the current oil price plunge?A)It is one that has seen no parallel in economic history.B)Its negative effects more than cancel out its positive effects.C)It still has a chance to give rise to a boom in the global economy.D)Its effects on the global economy go against existing economic laws.【答案】B55.Why haven’t falling oil prices boosted the global economy as they did before?A)People are not spending all the money they save on gas.B)The global economy is likely to undergo another recession.C)Oil importers account for a larger portion of the global economy.D)People the world over are afraid of a further plunge in oil prices.【答案】APart IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

You may not use any of the words in the bank more than once.Many men and women have long bought into the idea that there are “male”and“female”brains,believing that explains just about every difference between the sexes.A new study 26 that belief, questioning whether brains really can be distinguished by gender.In the study, Tel Aviv University researchers 27 for sex differences throughout the entire human brainAnd what did they find? Not much. Rather than offer evidence for 28 brains as “male” or“female”,research shows that brains fall into a wide range , with most people falling right in the middle.Daphna Joel ,who led the study, said her research found that while there are some gender‐based 29 ,many different types of brain can’t always be distinguished by gender.While the “average”male and“average”female brains were 30different, you couldn’t tell it by looking at individual brain scans. Only a small 31of people had “all-male”or“all-female”characteristics.Larry Cahill, an American neuroscientist(神经科学家),said the study is an important addition to a growing body of research questioning 32 beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same, 33 of gender.“There’s a mountain of evidence 34 the importance of sex influences at all levels of brain function ,”he told The Seattle Times.If anything, he said, the study 35that gender plays a very important role in the brain—“even when we are not clear exactly how.”Directions: In this section, there is a passage with ten blanks.

You may not use any of the words in the bank more than once.It’s our guilty pleasure: Watching TV is the most common everyday activity, after w ork and sleep, in many parts of the world. Americans view five hours of TV each day, a nd while we know that spending so much time sitting (36)can lead to obesity (肥胖症) and other diseases, researchers have now quantified just how(37)being a couch potato can be.In an analysis of data from eight large (38)published studies, a Harvard-led group reported in the Journal of the American Medical Association that for every two hours per day spent channel (39), the risk of developing Type 2 diabetes(糖尿病) rose 20% over 8.5 years, the risk of heart disease increased 15% over a (40), and the odds of dying prematurely (41)13% during a seven-year follow-up. All of these (42)are linked to a lack of physical exercise. But compared with other sedentary(久坐的) activities, like knitting, viewing TV may be especially (43)at promoting unhealthy habits. For one, the sh eer number of hours we pass watching TV dwarfs the time we spend on anything else. A nd other studies have found that watching ads for beer and popcorn may make you more likely to (44)them.Even so, the authors admit that they didn’t compare different sedentary activities to (45)whether TV watching was linked to a greater risk of diabetes, heart disease or ear ly death compared with, say, reading.A) climbed B) consume C) decade D) determine E) effective F) harmful G) outcomes H) passively I) previously J) resume K) suffered L) surfing M) term N) terminals O) twisting参考答案解析:36. passively解析:sitting passively 被动坐着从词性判断,36题应该选一个副词来修饰sitting这个动名词,而备选项中只有两个副词,一个是passively被动地,一个是previously之前,再根据语义逻辑,坐着那看电视的行为应该是一种被动行为,而不存在前后之分。

37. harmful解析:quantified just how harmful being a couch potato 量化长时间看电视的严重危害通过分析how ( ) being a couch potato can be 这句话的句子成分,得出how 这个副词之后应该接一个形容词,符合词性条件的备选项,一个是effective 有效的,一个是harmful 有害的。

根据语义逻辑,长时间看电视是有害的,故选harmful。

38. previously解析:previously published studies 之前公布的研究38题空格处应该填一个副词来修饰published这个词,参考36题的解析,备选项中现在只剩下一个副词就是previously,刚好填入此处。
