2019英语六级长篇阅读匹配练习题（3）2019英语六级长篇阅读匹配练习题(3)[A] We apply for credit for many reasons-maybe it's to buy a new car, house, computer, or get a student loan. However, that there is a special number that can determine whether you can do these things, or at least how much it will cost you. A credit score is a number that is calculated based on your credit history to give lenders a simpler "lend/don't lend" answer for people who are applying for credit or loans. This number helps the lender identify the level of risk they may be taking if they lend to someone. The credit score is quicker and less subjective. It's the credit score that makes it possible to get instant credit at places like electronics stores and department stores.[B] Although there are several scoring methods, the method most commonly used by lenders is known as a FICO because of its origins with Fair Isaac Corporation. Fair Isaac is an independent company that came up with the scoring method and software used by banks and lenders, insurers and other businesses. Each of the three major credit bureaus (Experian, Equifax and TransUnion) worked with Fair Isaac in the early 1980's to come up with the scoring method.[C] The three national credit bureaus each have their own version of the FICO score with their own names. Equifax has the Beacon system, TransUnion has the Empirica system, and Experian has the Experian/Falr Isaac system. Each is based on the original Fair Isaac FICO scoring method and produces equivalent numerical results for any given credit report. Some lenders also have their own scoring methods.Other scoring methods may include information such as yourincome or how long you've been at the same job.[D] Think of your credit score, like your grade in school. A teacher calculates grades by taking scores from tests, homework, attendance and anything else they want to use, weighting each one according to importance in order to come up with a final single number (or letter)score. Yourcredit score is calculated in a very similar manner. Insteadof using the scores from pop quizzes and reports you wrote, it uses the information in your credit report.[E] 35 percent of the score is based on your payment history. This makes sense since one of the primary reasons a lender wants to see the score is to find out if (and how timely)you pay your bills. The score is affected by how many bills have been paid late, how many were sent out for collection, any bankruptcies, etc. When these things happened also comes into play. The more recent, the worse it will befor your overall score.[F] 30 percent of the score is based on outstanding debt. How much do you owe on car or home loans? How many credit cards do you have that are at their credit limits? The more cards you have at their limits, the lower your score will be. The rule of thumb is to keep your card balances at 25% or less of their limits.[G] 15 percent of the score is based on the length oftime you've had credit. The longer you've had established credit, the better it is for your overall credit score. Why? Because more information about your past payment historygives a more accurate prediction of your future actions.[H] 10 percent of the score is based on the number of inquiries on your report. If you've applied for a lot of credit cardsor loans, you will have a lot of inquiries on your credit report. These are bad for your score because they indicate that you may be in some kind of financial trouble or may be taking on a lot of debt (even if you haven't used the cards or gotten the loans). The more recent these inquiries are, the worse for your credit score. FICO scores only count inquiries from the past years.[I] 10 percent of the score is based on the types of credit you currently have. The number of loans and available credit from credit cards you have makes a difference. Thereis no magic number or combination of types of accounts that you shouldn't have. These actually come more into play if there isn't as much other information on your credit report on which to base the score. This information is compared to the credit performance of other consumers with similar histories and profiles.[J] Your credit score doesn't just affect whether or not you get a loan; it also affects how much that loan is going to cost you. As your credit score increases, your credit risk decreases. This means your interest rate decreases. There are other factors that influence the interest rate you get for a loan besides your credit score. Things like the type of property you are using the loan to buy, how much of your own money is going into it, the costs the lender has to make the loan, etc.[K] In. addition to banks and lenders, there are landlords, merchants, employers and insurance companiesjumping on the credit score bandwagon (风靡的活动). Of all of these, the fact that insurance rates are being determined by credit scores is causing consumers the most alarm. To most, it seems that your credit history and your driving record have little in common. Insurers, on the other hand, have found thatusing credit scores to predict how likely someone is to pay premiums has helped them cut their losses. Theydon't use the same score that banks and lenders use, however. They use a slightly different formula for their calculations and actually call it an "insurance score".[ LJ Credit scores aren't static numbers. Because they are calculated based on your current credit report, they change every time your credit report changes. While this change may be very slight, it can also be much more dramatic. Here are some things some financial advisers say to do to try to improve your score.[M] Review your credit report and correct any errors you find. Getting rid of inaccurate information can sometimes improve your score dramatically.[N] Advice used to be given to close old and unused credit card accounts in order to reduce your "potential" available credit, which could change your debt ratio after you've been approved for a loan. Now, however, the ratio of your debt to your credit limit is more critical, so closing old accounts only raises that ratio-which you don't want to do. Some people have moved debt from several credit cards to one card and then closed the old accounts. Since creditors look at the debt-to- credit limit ratio, this can have a bad affect on your credit score because you have the same amount of debt but less available credit. So don't close old credit card accounts just because you're not using them.[O] Creditors also now look at the average age of your accounts so, again, keep those old accounts. Reduce your balances on credit cards to 75% or less of your available credit (25% is preferable). Pay your bills on time. (This is probably the most important of all!)Don't let anyone make an inquiry on your credit report unless you absolutely have to. The more inquiries,the lower your score. Don't open new credit card accounts just to increase your available creditin the hopes of raising your score. Also, remember that some improvements-such as better efforts at making payments on time-may take time to impact your score. So, time is also a factor.46. The credit score based on one's payment history accounts for 35 percent.47. FICO is the most frequently used credit scoring method.48. The credit score is calculated based on one's credit reports.49. Too many times of application for loans suggest that one may have some financial trouble.50. Credit score not only determines whether one can geta loan, but also affects how much one pays interest rate.51. To improve credit score, one should lay great effort not to delay the payment of bills.52. The basic role of a credit score is to determine whether applicants can get credit or loans.53. Credit score is a dynamic number that. varies with the change of one's current credit report.54. If you have more outstanding debt, you will get lower credit score.55. Closing old credit card accounts raises the debt-to-credit limit ratio, because the amount of available credit is reducing.46.The credit score based on one’s payment history accounts for 35 percent.。
2019年6月英语六级阅读模拟试题及详解答案(四)
2019年6月英语六级阅读模拟试题及ˇ解答案汇总Questions 56 to 60 are based on the followingpassage.They're still kids, and although there's a lot thatthe experts don't yetknow about them, one thingthey do agree on is that what kids use and expectfromtheir world has changed rapidly. And it's allbecause of technology.To the psychologists, sociologists, and generational and media experts whostudy them,their digital gear sets this new group apart, even from theirtech-savvy (懂技术的) Millennialelders. They want to be constantly connected andavailable in a way even their older siblingsdon't quite get. These differencesmay appear slight, but they signal anall-encompassingsensibility that some saymarks the dawning of a new generation.The contrast between Millennials and this younger group was so evident topsychologistLarry Rosen of California State University that he has declared thebirth of a new generation in anew book, Rewired: Understanding the ingenerationand the Way They Learn, out next month.Rosen says thetech-dominated lifeexperience of those born since the early 1990s is sodifferent from theMillennials he wrote about in his 2007 book, Me, MySpace and I: Parenting theNetGeneration, that they warrant the distinction of a new generation, which he hasdubbedthe "ingeneration"."The technology is the easiest way to see it, but it's also a mind-set, andthe mind-set goeswith the little ‘i', which I'm talking to stand for'individualized'," Rosen says. "Everything isdefined and individualized to ‘me'.My music choices are defined to ' me'. What I watch onTV any instant is definedto ‘me'. " He says the iGeneration includes today's teens and middle-school ers,but it's too soon to tell about elementary-school ages and younger.Rosen says the iGeneration believes anything is possible. "If they canthink of it, somebodyprobably has or will invent it," he says. "They expectinnovation."They have high expectations that whatever they want or can use "will beable to be tailoredto their own needs and wishes and desires."Rosen says portability is key. They are inseparable from their wirelessdevices, which allowthem to text as well as talk, so they can be constantlyconnected-even in class, where cellphones are supposedly banned.Many researchers are trying t6 determine whether technology somehow causesthe brainsof young people to be wired differently. "They should be distractedand should perform morepoorly than they do," Rosen says. "But findings showteens survive distractions much betterthan we would predict by their age andtheir brain development. "Because these kids are more immersed and at younger ages, Rosen says, theeducationalsystem has to change significantly."The growth curve on the use of technology with children isexponential(指数的), and werun the risk of being out of step with this generationas far as how they learn and how theythink," Rosen says."We have to give them options because they want their world individualized."56. Compared with their Millennial elders, the iGeneration kidsmunicate with others by high-tech methods continuallyB.prefer to live a virtual life than a real oneC.are equipped with more modem digital techniquesD.know more on technology than their elders57. Why did Larry Rosen name the new generation as iGenerationA.Because this generation is featured by the use of personal high-techdevices.B.Because this generation stresses on an individualized style of life.C.Because it is the author himself who has discovered the newgeneration.D.Because it's a mind-set generation instead of an age-set one.58.

2019大学英语六级长篇阅读匹配练习题及答案(三)
2019大学英语六级长篇阅读匹配练习题及答案(三) Section BGenetically Modified Foods--Feed the World?[A] If you want to spark a heated debate at a dinner party, bring up the topic about genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions--and vocal green lobbies--the idea seems against nature.[B] In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the U. S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U. S. this year. The genetic is out of the bottle.[C] Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from--and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent： Do the benefits of biotech outweigh the risks?[D] The statistics on population growth and hunger are disturbing. Last year the world's population reached 6billion. And by 2050, the UN estimates, it will be probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the world's available cultivable land per person is declining. Arable land has declined steadily since 1960 and will decrease by half overthe next 50 years, according to the International Service for the Acquisition of Agri-Biotech Applications ( ISAAA).How can biotech help?[E] Biotechnologists have developed genetically modified rice that is fortified with beta-carotene(胡萝卜素)--which thebody converts into vitamin A--and additional iron, and theyare working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attribution to pests, drought, poor soil and crop viruses, bacteria or fungi ( 真菌 ).[F] Damage caused by pests is incredible. The European corn borer, for example, destroys 40 million tons of the-world's corn crops annually, about 7% of the total. Incorporatingpest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa, yields have increased significantly. So far, fears that genetically modified, pest-resistant crops might kill good insects aswell as bad appear unfounded.[G] Viruses often cause massive failure in staple crops in developing countries. Two years ago, Africa lost more thanhalf its cassava (树薯) crop--a key source of calories-to themosaic virus (花叶病毒).Genetically modified, virus-resistant crops can reduce that damage, as can drought-tolerant seeds in regions where water shortages limit the amount of land under cultivation. Biotech can also help solve the problem of soil that contains excess aluminum, which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity (毒性) in rice has been identified. Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and help prevent the loss of those crops after they are harvested.[H]Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause ofhunger. Poverty plays the largest role. Today more than 1 billion people around the globe live on less than 1 dollar a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to grow them or if the local population cannot afford to buy the food those farmers produce.[I] Biotech has its own "distribution" problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products won't even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companies are responding to needs of poor countries.。

大学英语六级阅读段落匹配真题及答案因考试政策、内容不断变化与调整，下面给大家整理的高校阅读理解真题供参考，以下是我给大家整理的高校英语六级阅读段落匹配真题及答案，期望可以帮到大家Section ADirections:In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Countries Rush for Upper Hand in AntarcticaA) On a glacier-filled island with fjords(峡湾)and elephant seals, Russia has built Antarcticas first Orthodox church on a bill overlooking its research base. Less than an hour away by snowmobile. Chinese laborers have updated the Great Wall Station, a vital part of Chinas plan to operate five basses on Antarctica, complete with an indoor badminton court and sleeping quarters for 150 people. Not to be outdone, Indias futuristic new Bharathi base, built on stills(桩子)using 134 interlocking shipping containers, resembles a spaceship. Turkey and Iran have announced plans to build bases, too.B) More than a century has passed since explorers raced toplant their flags at the bottom of the world, and for decades to come this continent is supposed to be protected as a scientific preserve, shielded from intrusions like military activities and mining . But an array of countries are rushing to assert greater influence here, with an eye not just towards the day those protective treaties expire, but also for the strategic and commercial that already exist.C) The newer players are stepping into what they view as a treasure house of resources. Some of the ventures focus on the Antarctic resources that are already up for grabs, like abundant sea life. South Korea, which operates state-ofthe-art bases here, is increasing its fishing of krill(磷虾)，found in abundance in the Southern Ocean, while Russia recently frustrated efforts to create one of the worlds largest ocean sanctuaries here.D) Some scientists are examining the potential for harvesting icebergs form Antarctica, which is estimated to have the biggest reserves of fresh water on the planet. Nations are also pressing ahead with space research and satellite projects to expand their global navigation abilities.E) Building on a Soviet-era foothold, Russia is expanding its monitoring stations for Glonass, its version of the Global Positioning System(GPS). At least three Russian stations are already operating in Antarctica, part of its effort to challenge the dominance of the American GPS, and new stations are planned for sites like the Russian base, in the shadow of the Orthodox Church of the Holy Trinity.F) Elsewhere in Antarctica, Russian researchers boast of their recent discovery of a freshwater reserve the size of Lake Ontario after drilling through miles o f solid ice. “You can see that were here to stay,” said Vladimir Cheberdak, 57, chief of the Bellingshausen Station, as he sipped tea under a portrait of Fabian Gottlieb von Bellingshausen, a high-ranking officer in the Imperial Russian Navy who explored the Antarctic coast in 1820.G) Antarcticas mineral, oil and gas wealth are alonger-term prize. The treaty banning mining here, shielding coveted(令人垂诞的)reserves of iron ore, coal and chromium, comes up for review in 2048. Researchers recently found kimberlite(金伯利岩) deposits hinting at the existence of diamonds. And while assessments vary widely, geologists estimate that Antarctica holds at least 36 billion barrels of oil and natural gas.H) Beyond the Antarctic treaties, huge obstacles persist to tapping these resources, like drifting icebergs that could jeopardize offshore platforms. Then there is Antarctics remoteness, with some mineral deposits found in windswept locations on a continent that is larger the Europe and where winter temperatures hover around minus 55 degrees Celsius.I) But advances in technology might make Antarctica a lot more accessible three decades from now. And even before then, scholars warn, the demand for resources in an energy-hungry world could raise pressure to renegotiate Antarcticas treaties, possibly allowing more commercial endeavours here well before the prohibitions against them expire. The research stations onKing George lsland offer a glimpse into the long game on this ice-blanketed continent as nations assert themselves, eroding the sway long held by countries like the United States, Britain. Australia and New Zealand.J) Being stationed in Antarctica involves adapting to life on the planets driest, windiest and coldest continent, yet each nation manages to make itself at home. Bearded Russian priests offer regular services at the Orthodox church for the 16 or so Russian speakers who spend the winter at the base, largely polar scientists in fields like glaciology and meteorology. Their number climbs to about 40 in the warmer summer months. China has arguably the fastest growing operations in Antarctica. It opened its fourth station last year and is pressing ahead with plans to build a fifth. It is building its second ice-breaking ship and setting up research drilling operations on an ice dome 13,422 feet above sea level that is one the planets coldest places. Chinese officials say the expansion in Antarctica prioritises scientific research. But they also acknowledge that concerns about “resource security” influence their moves.K) Chinas newly renovated Great Wall Station on King George lsland makes the Russian and Chilean bases here seem outdated. ”We do weather monitoring here and other research.” Ning Xu, 53, the chief of the Chinese base, said over tea during a fierce blizzard(暴风雪) in late November. The large base he leads resembles a snowed-in college campus on holiday break, with the capacity to sleep more than 10 times the 13 people who were staying on through the Antarctic winter. Yong Yu, a Chinese microbiologist, showed off the spacious building, with emptydesks under an illustrated timeline detailing the rapid growth of Chinas Antarctic operations since the 1980s “We now feel equipped to grow,” he said.L) As some countries expand operations in Antarctica, the United States maintains three year-round stations on the continent with more than 1,000 people during the southern hemispheres summer, including those at the Amundsen Scott station, built in 1956 at an elevation of 9,301 feet on a plateau at the South Pole. But US researchers quietly complain about budget restraints and having far fewer icebreakers the Russia, limiting the reach of the United States in Antarctica.M) Scholars warn that Antarcticas political drift could blur the distinction between military and civilian activities long before the continents treaties come up for renegotiation, especially in parts of Antarctica that are ideal for intercepting(拦截) signals from satellites or retasking satellite systems, potentially enhancing global electronic intelligence operations.N) Some countries have had a hard time here, Brazil opened a research station in 1984, but it was largely destroyed by a fire that killed two members of the navy in 2023, the same year that a diesel-laden Brazilian barge sank near the base. As if that were not enough. a Brazilian C-130 Hercules military transport plane has remained stranded near the runway of Chiles air base here since it crash-landed in 2023.O) However, Brazils stretch of misfortune has created opportunities for China, with a Chinese company winning the$100 million contract in 2023 to rebuild the Brazilian station.P) Amid all the changes, Antarctica maintains its allure. South Korea opened its second Antarctic research base in 2023, describing it as a way to test robots developed by Korean researchers for use in extreme conditions. With Russias help, Belarus is preparing to build this first Antarctic base. Colombia said this year that it planned to join other South American nations with bases in Antarctica.Q) “The old days of the Antarctic being dominated by the interests and wishes of white men from European. Australasian and North American states are over.” Said Klaus Dodds, a politics scholar at the University of London who specialises in Antarctica. “The reality is that Antarctica is geopolitically contested.”36. According to Chinese officials, their activities in Antarctica lay greater emphasis on scientific research.37. Efforts to create one of the worlds largest ocean sanctuaries failed because of Russias obstruction.38. With several monitoring stations operating in Antarctica, Russia is trying hard to counter Americas dominance in the field of worldwide navigational facilities.39. According to geologists estimates. Antarctica has enormous reserves of oil and natural gas.40. It is estimated that Antarctica boasts of the richestreserves of fresh water on earth.41. The demand for energy resources may compel renegotiation of Antarcticas treaties before their expiration.42. Many countries are racing against each other to increase their business and strategic influence on Antarctica.43. Antarcticas harsh natural conditions constitute huge obstacles to the exploitation of its resources.44. With competition from many countries, Antarctica is no longer dominated by the traditional white nations.45. American scientists complain about lack of sufficient money and equipment for their expansion in Antarctica.参考答案Section BCountries Rush for Upper Hand in Antarctica36. [J]37. [C]38. [E]39. [G]40.

2019年12月英语六级长篇阅读匹配练习题（1）2019年12月英语六级长篇阅读匹配练习题（1）It's Time to Pay Attention to SleepA．After being diagnosed with brain and lung cancer in 2011, Lynn Mitchell, 68, was averaging about an hour of solid sleep a night． Stressed about her treatments, she was paying for it in hours of lost sleep．B．The brain cancer was already affecting her mobility--Mitchell was often dizzy and would lose her balance--but the lack of sleep made things worse． Even walking became increasingly difficult．Exhausted in the mornings, she was practically incoherent (精神恍惚)． When her doctors recommend she see a sleep therapist, Mitchell was relieved at how benign it sounded in comparison to the chemotherapy (化学疗法)she had undergone and the gene therapy trial she was undergoing, which had side effects like nausea and fatigue．C．For about nine weeks, Mitchell worked with the sleep therapist to adjust her sleep habits． She went to bed only when she was extremely fired．She quit watching TV in bed．She stopped drinking caffeinated (含咖啡因的) coffee in the evening． She also learned breathing exercises to relax and help her fall asleep． It was all quite simple and common sense, and most importantly, noninvasive and didn't require taking any pills．D． "It's common knowledge that sleep is needed for day to day function," says Dr．David Rapoport, director of the Sleep Medicine Program at NYU School of Medicine． "What isn't common knowledge is that it really matters--it's not just cosmetic．" Rapoport has long seen people seek sleep therapybecause they're chronically fired or suffering from insomnia, but an increasing number of patients are being referred to his center for common diseases, disorders, and mental health．E．Researchers have known for some time that sleep is critical for weight maintenance and hormone balance． And too little sleep is linked to everything from diabetes (糖尿病) to heart disease to depression．Recently, mounting evidence indicates that sleep plays a role in nearly every aspect of health． Beyond chronic illnesses, a child's behavioral problems at school could be rooted in mild sleep apnea (呼吸暂停)． And studies have shown children with ADHD (注意力缺陷多动症) are more likely to get insufficient sleep． A recent study published in the journal SLEEP found a link between older men with poor sleep quality and cognitivedecline．Another study shows sleep is essential in early childhood for development, learning, and the formation and retention of memories．F．But to many of us, sleep is easily sacrificed, especially since lack of it isn't seen as life threatening．Over time, sleep deprivation can have serious consequences, but we mostly sacrifice a night of sleep here and there, and always say that we'll "catch up．" Luckily, it is possible to make up for sleep debt (though it can take a very long time), but most Americans are still chronically sleep deprived．G． While diet and exercise have been a part of public health messaging for decades, doctors and health advocates are now beginning to argue that getting quality sleep may be just as important for overall health． "Sleep is probably easier to change than diet or exercise," says Dr． Michael Grandner , a sleep researcher at the University of Pennsylvania． "It may alsogive you more of an immediate reward if it helps you get through your day．" Sleep experts claim that it is one of the top three, and sometimes the most, important lifestyle adjustments one can make, in addition to diet and exercise．And while there's more evidence linking diet and exercise as influential health factors, sleep is probably more important in terms of brain and hormonal function． "Among a small group of sleep researchers, it's always been said that eating, exercise, and sleep are the three pillars of health," says Dr． Rapoport．H． In our increasingly professional and digital lives, carving out time for sleep is not only increasingly difficult, but also more necessary．Using technology before bed stimulates us and interferes with our sleep, yet 95% of Americans use some type of electronics like a computer, TV,or cell phone at least a few nights a week within the hour before we go to bed, according to a 2011 National Sleep Foundation survey． "Many doctors, lawyers, and executives stay up late and get up early and bum the candle at both ends," says Dr． Richard Lang, chair of Preventative Medicine at the Cleveland Clinic． "Making sure they pay attention to sleep in the same way they pay attention to diet and exercise is crucial．"I．To some, sleep has become a powerful cure to mental health． Arianna Huffington, president and editor-in-chief of the Huffington Post Media Group, advocates that sleep is the secret to success, happiness, and peak performance． After passing out a few years ago from exhaustion and cracking a cheekbone against her desk, Huffington has become something of a sleep evangelist (传道者)．In a 2010 TED Women conference, Huffington said, "The way to a more productive,more inspired, more joyful life is getting enough sleep．" Research linking high-quality sleep with better mental health is growing; a 2013 study found that treating depressed patients for insomnia can double their likelihood of overcoming the disorder．J． While 70% of physicians agree that inadequate sleepis a major health problem, only 43% counsel their patients on the benefits of adequate sleep． But there's growing pressure on primary care physicians to address, and even prescribe, sleep during routine check-ups． In a recent study published in the journal The Lancet Diabetes & Endocrinology, the researchers concluded that health professionals should prescribe sleep to prevent and treat metabolic disorders like obesity and diabetes．K． On the other hand, overlooking sleep as a majorhealth issue can also have deadly consequences．It was recently reported that the operator of the Metro-North train that derailed in New York last year, killing four people and injuring more than 70, had an undiagnosed case of sleep apnea．L．Sleep therapies can range from simply learning new lifestyle behaviors to promote sleep, to figuring out how to position oneself in bed．More drastic measures involve surgery to open up an airway passage for people suffering from disorders like sleep apnea． Sleeping pills can be prescribed too, to get much needed rest, but sleep therapists tend to favor other approaches because of possible dependencies developing．M． A large part of reaping the benefits of sleep is known when you're not getting the right amount．According to a 2013 Gallup survey, 40% of Americans get less than the recommended seven to eight hours a night． While the typical person still logsabout 6．8 hours of sleep per night, that's a drop from the 7．9 Americans were getting in the 1940s．N．When it comes to adequate sleep, it's much more personalized than previously thought． Some people feel great on five hours of rest, while others need ten． The best way to determine if you're getting the right amount, doctors say, is to find out how many hours of sleep you need to be able to wake up without an alarm and feel rested, refreshed, and energetic throughout the day．O．Since reforming her sleep habits, Mitchell has been clocking up to seven hours of shuteye a night for the past two months． "I'm alert in the morning, my balance is better, and I feel more energetic," says Mitchell． Getting enough sleep has helped her better deal with her cancers, and its symptoms． The best news is that she recently found out that her brain tumor is shrinking, and there are fewer cancerous spots on her lungs．46． According to Rapoport, people fail to fully realize the importance of sleep．47．The amount of time for an adequate sleep actually varies from person to person, and thus relies on personal judgment．48． The positive role of sleep therapy in treating depression indicates that sleep also contributes to mental health．49． Compared to the sleep therapy, the other therapies that Mitchell has to go through have some negative side effects．50． Now work and electronic products may play a role in depriving Americans of time for sleep．51． Mitchell has benefited much from sleep therapy in the fight against her brain and lung cancers．52． Among the various methods in sleep therapy, sleepingpills are usually the last choice by health professionals．53． It is recommended that physicians should adopt sleep as a way to prevent or treat some illnesses．54．It is now argued that high-quality sleep is no less important than diet and exercise in affecting health．55．Recent studies show that sleep is related to the behavioral problems of the kids and the cognitive abilities of the old．。
2019年12月大学英语六级考试阅读模拟题及答案4
2019年12月大学英语六级考试阅读模拟题及答案4Work is a very important part of life in the United States. When the early Protestant immigrants came to this country,they brought the idea that work was the way to God and heaven. This attitude, the Protestant work ethic, still influences America today. Work is not only important for economic benefits, the salary, but also for social and psychological needs, the feeling of doing something for the good of the society. Americans spend most of their lives working, being productive. For most Americans, their work defines them; they are what they do. What happens, then when a person can no longer work?Most Americans stop working at age sixty-five or seventy and retire. Because work is such an important part of life in this culture, retirement can be very difficult. Retireesoften feel that they are useless and unproductive. Of course, some people are happy to retire; but leaving one’s job, whatever it is a difficult change, even for those who look forward to retiring. Many retirees do not know how to usetheir time or they feel lost without jobs.Retirement can also bring financial problems. Many people rely on Social Security checks every month. During their working years, employees contribute a certain percentage of their salaries to the government. When people retire, they receive this money as income. These checks do not provide enough money to live on, however, because prices areincreasing very rapidly. Senior citizens, those over sixty-five, have to have savings in the bank or other retirement plans to make ends meet. The rate of inflation is forcingprices higher each year; Social Security checks alone cannot cover Medicare (health care) and welfare (general assistance) but many senior citizens have to change their lifestylesafter retirement. They have to spend carefully to be surethat they can afford to but food, fuel, and other necessities.Of course, many senior citizens are happy with retirement. They have time to spend with their families or to enjoy their hobbies. Some continue to work part time; others do volunteer work. Some, like those in the Retired Business Executives Association, even help young people to get started in new business. Many retired citizens also belong to “Golden Age” groups. These organizations plan trips and social events. There are many opportunities for retirees.Americans society is only beginning to be concerned about the special physical and emotional needs of its senior citizens. The government is taking steps to ease the problemof limited income. They are building new housing, offering discounts in stores and museums and on buses, and providing other services, such as free courses, food service, and help with housework. Retired citizens are a rapidly growing percentage of the population. This part of the population is very important and we must respond to their needs. After all, every citizen will be a senior citizen some day.1.The early immigrants considered work ___.A.too hardB.importantC.pleasantD.dull2.Why do Americans like working?

2019 六级长篇阅读匹配练习题及答案（四）Section BHow "Second Brain" Influences Mood and Well-Being [A] As Olympians go for the gold in Vancouver, even the steeliest are likely to experience that familiar feeling of "butterflies" in the stomach. Underlying this sensation is an ofte n-o verlooked n etwork of neurons （神经元）li ning our guts that is so extensive some scientists have nicknamed it our "second brain". A deeper understanding of this mass of neural tissue is revealing that it does much more than merely handle digestion or inflict the occasional nervous pang. The little brain in our gut, in connection with the big one in our head, partly determines our mental state and plays key roles in certain diseases throughout the body.[B]Although its influence is far-reaching, the second brain is not the seat of any conscious thoughts or decision-making. "The second brain doesn't help with the great thought processes ... religion, philosophy and poetry is left to the brain in the head," says Michael Gershon, chairman of the Department of Anatomy and Cell Biology at New York- Presbyterian Hospital/Columbia University Medical Center, author of the 1998 book The Second Brain.[C]Technically known as the enteric （肠内的）nervous system, the second brain consists of covers of neurons embedded in the walls of the long tube of our gut, which measures about nine meters end to end. The second brain contains some 100 million neurons, Gershon says. This multitude of neurons in the enteric nervous system enables us to "feel" the innerworld of our gut and its contents. Much of this neural firepower comes to bear in the elaborate daily grind of digestion. Breaking down food, absorbing nutrients, and expelling of waste requires chemical processing, mechanical mixing and rhythmic musclecontractions that move everything on down the line.[D]Thus equipped with its own reactions and senses, the second brain can control gut behavior independently of the brain, Gershon says. We likely evolved this intricate web of nerves to perform digestion and ejection "on site," rather than remotely from our brains through the middleman of the spinal cord （脊髓）. "The brain in the head doesn't need to get its hands dirty with the messy business of digestion, which is delegated to the brain in the gut," Gershon says. He and other researchers explain, however, that the second brain's complexity likely cannot be interpreted through this process alone.[E] "The system is way too complicated to have evolved only to make sure things move out of your bowel," says Emeran Mayer, professor of physiology, psychiatry and biobehavioral sciences at the David Geffen School of Medicine at the University of California, Los Angeles （ U. C. L. A. ）. For example, scientists were shocked to learn that about 90 percent of the fibers in the primary gut nerve, the vagus （走神经）, carry information from the gut to the brain and not the other way around. "Some of that information is decidedly unpleasant," Gershon says.[F]The second brain informs our state of mind in other more obscure ways, as well. "A big part of our emotions are probably influenced by the nerves in our gut," Mayer says. Butterflies in the stomach-signaling in the gut as part of our physiological stress response, Gershon says--is but one example. Although gastrointestinal （肠胃）（GI）chaos can sour one's moods, everyday emotional well-being may rely on messages from the brain below to the brain above. For example, electrical stimulation of the vagus nerve-a useful treatment for depression-may mimic thesesignals, Gershon says.[G]Given the two brains' commonalities, other depression treatments that target the mind can unintentionally impact the gut. The enteric nervous system uses more than 30 neurotransmitters,just like the brain, and in fact 95 p erce nt of the body's serot onin （血清素）is found in the bowels.Because antidepressant medications called selective serotonin reuptake inhibitors （选择性无羟色胺再摄取抑制剂）（SSRIs）increase serotonin levels, it's little wonder that reeds （椎间盘镜）meant to cause chemical changes in the mind often provoke GI issues as a side effect. Irritable bowel syndrome-which afflicts more than two million Americans-also arises in part from too much serotonin in our guts, and could perhaps be regarded as a "mental illness" of the second brain.[H]Scientists are learning that the serotonin made by the enteric nervous system might also play a role in more surprisingdiseases ： In a new Nature Medicine study published online February 7, a drug that inhibited the release of serotonin from the gut counteracted the bonedeteriorating disease osteoporosis （骨质疏松症）. "It wastotally unexpected that the gut would regulate bone mass to the extent that one could use this regulation to cure osteoporosis," says Gerard Karsenty, lead author of the study and chair of the Department of Genetics and Development at Columbia University Medical Center.[I]S erotonin penetrating from the second brain might even play some part in autism （孤独症）, the developmental disorder often first noticed in early childhood. Gershon has discovered thatthe same genes involved in synapse formation （突触形成）between neurons in the brain are involved in the digestive synapse formation. "of these genes are affected in autism," he says, "it could explain why so many kids with autism have GI motor abnormalities in addition to elevated levels of gut-produced serotonin in their blood. "[J]Down the road, the blossoming field of neurogastroenterologywill likely offer some new insight into the workings of the second brain-and its impact on the body and mind." We have never systematically looked at the enteric nervous system in relating damages in it to diseases like they have for the central nervous system", Gershon says. One day, perhaps there will be well-known connections between diseases and damages in the gut's nervous system as some in the brain and spinal cord today indicate multiple sclerosis.[K] Cutting-edge research is currently investigating how the second brain mediates the body's immune response; after all, at least 70 percent of our immune system is aimed at the gut to expel and kill foreign invaders. U. C. L. A. 's Mayer is doing work on how the trillions of bacteria in the gut "communicate" with enteric nervous system cells （which they greatly outnumber）. His work with the enteric nervous system has led him to think that in coming years psychiatry will need to expand to treat the second brain inaddition to the one above the shoulders.[L] So for those physically skilled and mentally strong enough to compete in the Olympic Games-as well as those watching at home-it may well necessary for us all to pay more heed to our so-called "gut feelings" in the future.46. The second brain does not deal with the activities of advancedthinking.47. Some scientists have called the network of neurons in guts "second brain".48. Apart from elevated levels of gut-produced serotonin in their blood, children with autism are believed to have GI disorder.49. Meds often provoke GI issues as a side effect in that SSRIs increase serotonin levels.50. The author suggested that athletes in the Olympics and audience should pay more attention to gut feelings.51. Cutting-edge research is now focusing on the way the second brain adjusts the body's immune response.52. Many of our emotions may be brought about by the second brain.53.The second brain with its own reactions and senses is certain to give direction to gut system independently.54.It will soon be necessary for psychiatry to treat both the brain in the head and the second brain.55.The second brain enables us to feel the inner world of our body through multitude of neurons.。
2019年六级考试阅读练习题(4)
2019年六级考试阅读练习题（4）Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can't be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone in bed, taking no notice of the worms. But is it interfering with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.Indeed, the old can be easily hurt or harmed. The bodyis like a car, it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results. And at what point should you cease to treat the old body? Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate(激活) the old body, knowing that it is designed to die? You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, theywill feel bound to give them a try, on the principle that while there's life, there's hope.When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on yourability to have fun.21. It is implied in Paragraph 1 that______.A. very old people enjoy living with their relativesB. social services have nothing to do with very old peopleC. very old people would like to live alone so that they can have more personal freedomD. very old people are able to keep their rooms very clean22. Some social workers think that______.A. health and safety are more important than personal freedomB. personal freedom is more important than health and safetyC. old people should keep their rooms cleanD. one should not take the risk of dealing with old people23. In the author's opinion, ______.A. the human body can't be compared to a carB. the older a person, the more care he needsC. too much emphasis has been put on old people's valuesD. it is easy to provide spare parts for old people24. The word "it" in the last paragraph refers to______.A. the conclusion you have come toB. your talk to the old peopleC. whether age is happy or unpleasantD. one's money or one's health25. The author thinks that______.A. medical decisions for old people should be left to the doctorsB. old people can enjoy a happy life only if they are very richC. the opinion that we should try every means possible to save old people is doubtfulD. it is always morally right to treat old people and push off death答案：21.

2019年英语六级阅读理解试题库及答案(3)President Arling has put his long awaited economic restructuring program before the Congress. It provides a coordinated program of investment credits, research grants, education reforms, and tax changes designed to make American industry more competitive. This is necessary to reverse the economic slide into unemployment, lack of growth, and trade deficits that have plagued the economy for the past six years.The most liberal wing of the President's party has called for stronger and more direct action. They want an incomes policy to check inflation while federal financing helps rebuild industry behind a wall of protective tariffs.The Republicans, however, decry even the modest, graduated tax increases in the President’s program. They want tax cuts and more open market. They say if federal money has to be injected into the economy, let it through defence spending.Both these alternatives ignore the unique nature of the economic problem before us. It is not simply a matter of markets or financing. The new technology allows vastly increased production for those able to master it. But it also threatens those who fail to adopt it withermanent second-class citizenship in the world economy. If an industry cannot lever itself up to the leading stage of technological advances, then it will not be able to compete effectively. If it cannot do this, no amount of government protectionism or access to foreign markets can keepit profitable for long. Without the profits and experience of technological excellence tore invest, that industry can only fall still further behind its foreign competitors.So the crux is the technology and that is where the President’s program focused. The danger is not that a plan will not be passed, it is that the ideologues of right and left will distort the bill with amendments that will blur its focus on technology. The economicretructuring plan should be passed intact. If we fail to restructure our economy now, we may not get a second chance.1. The focus of the President's program is on[A] investment.[B] economy.[C] technology.[D] tax.2. What is the requirement of the most liberal wing of the Democratic-party?[A] They want a more direct action.[B] They want an incomes policy to check inflation.[C] They want to rebuild industry.[D] They want a wall of protective tariffs.3. What is the editor's attitude?[A] support.[B] distaste.[C] Disapproval.[D] Compromise.4. The danger to the plan lies in[A] the two parties' objection.[B] different idea of the two parties about the plan.[C] its passage.[D] distortion.5.

Part of the blame can be placed on crowded airports and airspace, especially in heavily trafficked (交通繁忙的) areas like New York City．But delays and inefficiencies in air travel are due in large part to an outdated traffic-control system that still relies on slow, ground-based radar stations and repetitive voice communication．B) "At this' point, we're still operating with technology that dates back to World War II," says Marion Blakey, president of the Aerospace Industries Association and a former head of the Federal Aviation Administration(FAA) ．"We’re sticking with cassette tapes when we should be moving to DVDs．"C) It's bad enough that this air-traffic-control system has led to pitiful performance： nearly 25% of U．S．flights were late in 2008． But inefficiencies in the air and on the ground caused by the system also mean fuel wasted and carbon dioxide (CO2) emitted at the very time when the air-travel industry is coming under scrutiny (审查) for its role in climate change．D) Though airlines contribute only about 2% of global carbon emissions, that figure is set to rise as air travelexpands, especially in the developing world And for frequent travelers, flights can enlarge their personal carbonfootprint (碳足迹)一a round-trip journey between New YorkCity and London emits 1．5 metric tons of CO2 per passenger． "We're 2%, but we are a very visible 2%," says Paul Steele, who directs environmental initiatives for the International Air Transport Association (IATA) ．E) As the world prepares for the next U．N． Climate Change Conference, known as COP15, in Copenhagen in December, the air-travel industry will be under increasing pressure to cut its emissions---or pay a carbon tax． Though next-generation jet biofuels (生物燃料) made from algae (海藻) or coconuts tend to get all the green hype (大肆宣传) , the best immediate opportunity for the industry to control carbon emissions will be through improving fuel efficiency--and the best way to do that is to pull the airtraffic-control system into the digital 21 st century through what the FAA has named NextGen． "The overall goal of NextGen is to increasecapacity to meet demand while at the same time not growing carbon emissions," says Vicki Cox, the FAA's senior vice president for NextGen．F) NextGen is the FAA's long-term plan to replace the current radar-based air-traffic-control system with one that operates using satellites and a global positioningsystem． (Europe is working on a similar upgrade with its Single European Sky initiative．． Instead of a radar system that updates the positions of planes every 12 seconds or so, NextGen will use satellite data to locate planes in real time, thanks to the Automatic Dependent Surveillance-Broadcast (ADS-B 广播式自动相关监视) system． Instead of relying ontime-consuming voice communication with a control tower, pilots will instantly know the location, speed and direction of the planes around them． It's not unlike the GPS system you might use in your car--if your GPS could tell you what every other vehicle on the road was doing all the time．G) "The new system gives pilots a heightened awareness of the airspace around them and helps controllers efficiently direct the tens of thousands of flights that crisscross (往返奔波) the country daily," says Steve Loranger, chief executive of ITT Corporation, which is developing the ADS-B system for the FAA)H) A satellite-based system like NextGen will allow for tighter, more direct flight paths--more A to B instead of A to C to B. Every minute cut from a flight plan means lessfuel and less carbon emissions．And with jet fuel costing about $1．75 per gallon (46 cents per liter． , that could save the airlines millions．I) Much of those savings will come during approach (进场) and landing． Because the current system is less precise, controllers need to give planes plenty of room as they lock onto the runway, descending in a slow, steppedapproach． NextGen will allow planes to make what is called a continuous-descent approach (CDA) , essentially letting them turn off their engines, saving tons of fuel and reducing pollutants．J) At the airport in Louisville, Kentucky, where UPS has been experimenting with a satellite-based control system, the shipper has been able to use CDA for landings and maximize the number of planes in the air at any given time． UPS。

Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph ismarked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Six Steps to Tackling Your Student Loans[A] Any payment is a good debt payment, but a strategy canbe useful too-even if your strategy means opening the envelope.Open the envelope[B]This is the hardest thing to do. The bills come with the "Sallie Mae" or "Discover" logo on them and you toss them aside, hoping to deal with them when you feel less besieged ( 围攻 ). You know you started owing some amount- $20,000, $50,000, $100,000 —and that the interest is piling up, butyou don't know exactly how much or how. When faced with heavy debt, many people try to avoid seeing the numbers.[C]This doesn't work, even psychologically. Anyone who haslet credit-card bills or mortgage bills pile up, 1reopened,knows that avoiding the envelope does not reduce your anxiety; it increases it. As those envelopes multiply, they take over your psychological state. In horror movies, it's like the monster in the room behind the door. You don't know what itlooks like, but it keeps you scared and immobile. So,open the envelope.[D] Or, even better, log in online. All student loanproviders have a web site where you can see what you owe,your interest rates, and your payment schedules. SallieMae.com is no-frills, but still allows you to see your loans on onescreen, including your interest rates. Discover. corn alsohas a pretty basic site. Citibank has a more complex site.Get used to logging into these sites pretty often; ff you need motivation, think of it as visiting your money while it's inprison.[E] The websites all have one thing in common：they let you see how much you owe, and what your interest is, and theymake it easy to pay-but they don't let you see how much yourdebt load is growing. This is a major motivating factor inpaying down your loans. Identify your loans[F]Are your loans held by the federal government--usuallythrough Sallie Mae--or through "private" lenders like Citibankor Discover? if you don't know who holds your loans, you canfind out here, at the National Student Loan Data System.[G]Why do you need to know who holds your loans? This willmake a difference to your payment options and your interestrates, if you have a federal loan, for instance, yourinterest rate is probably very low, around 32% ; ff you haveprivate loans, the interest rates are likely to be much higher,around 48%. Federal loans also give you options likerequesting forbearance (延期还贷) ff you're out of work or ifyour income is too low-handy for the times when you're down on your luck.Start seeing your debt in new ways[H]The websites of lenders are often limited and onlyhave basic information. To really tackle your student loans,it can often be useful to visualize how much progressyou're making. There are several ways to do that.[I]One really useful new free site is Tuition. io, whichgathers information for all your loans in one place. You cansee your debt in colorful charts, play around with repayment plans, and, once you start paying your loans, you can see the numbers start to fall. That can be very motivating.[J]For the same effect that you can customize yourself, trya Google Docs spreadsheet. There's a template that already exists for paying down loans; it has the unpromising title of "Loan amortization schedule by Vertex42. corn" but it hasvery handy calculators built in so that you can tweak your monthly payments to see how much progress you can make if you increase or decrease your payments in any given month. If you don't like that template, just create a Google Docs spreadsheet with the categories you need ： date; loanname/number; loan interest rate; starting loan amount( including how much you owe on that date) ; payment amount you made on that date; ending loan amount after that payment. After you have enough entries, you can start creating graphs; there are few things more satisfying than seeing that graph move downward as you pay off your debt.[K] If you want to see your loans in a larger context ofyour whole financial picture, LearnVest is a great mobile app for iPhone. It gathers all your information income, loans, credit card debt by linking to your accounts. It serves up useful graphs on your net worth, comparing your assets to what you owe -and there's nothing more motivating than seeing a "minus" sign next to your financial picture. LearnVest"also lets you track your spending, which may make it easierto see where to cut down on expenses so that you can put more into your loan payments. LearnVest also has a good website full of useful advice .Don't be afraid to scare yourself [L] Student loans can often be scary and that's Why you should slay them. The more you see how much you owe, and how fast your interest is rising, the more motivated you can be to fight back by paying those loans. One staffer, after she saw how much money she was wasting on interest payments, increased her student loan payments by $ 75 a month.[M]It can also be tempting to believe that your student debtis so big that nothing you do can ever make a dent in it.That's completely untrue. Only paying your loans will shrink them. It will take years, true. It will take even longer ifyou don't pay, or pay the minimum. There's only one outcome of shirking your loans ： ending up with bigger loans. Then you're in an even bigger bind. No one is going to save you from student loans. Action counts.Choose a strategy[N] Any payment is a good payment, but a strategy can be very useful too. There are two aspects to loans ：principal and interest .Principal is how much you've borrowed ,and theinterest is what you're paying every month for the privilege ofhaving borrowed that money. Your goal is to pay down asmuch of the principal as possible. Your chief enemy here isinterest ： it grows fast, and makes the principal recede more distantly.[O]So make sure you know the rank of your loans, in orderfrom smallest to largest, and lowest interest to highestinterest. Do whatever is possible to reduce the interest; asour columnist Helaine Olen points out, Sallie Mac offers youa 0. 25% reduction in your loan interest if you sign up foran automatic debit (借方) plan--just make sure the money isalways going to be in your account. If you don't want to dothat, follow Helaine's other piece of advice ： you're smarter to pay off the loans with the higher interest rate flint.This will create the biggest impact. Another popular strategyis the "snowball" method, where you pay the most on thesmallest debt owed. So if you have a $20,000 loan and a$10,000 loan, the "snowball" method means you will startpaying more towards the $10,000 loan. You'll see it disappear faster. These two methods don't always go together; so trywhat feels comfortable. The important thing is to see andtrack your progress.[P]If your income isn't enough, consider other methods ofproducing money ： side projects, odd jobs, or selling thingsyou don't need on eBay or Craigslist. For those whose parentscan afford it, working out a joint payment plan can makesense. One graduate we know struck a savvy (精明的) deal with his parents ： if he made the minimum student loan paymentevery month, they would contribute $100 toward his studentloans. That's $100 he doesn't have to cut from his own budget.As a benefit, making bigger payments will help you pay down the principal of the loan, since the minimum payments often only end up reducing your interest, which balloons back later. Even $ 50 more a month can help.[Q]Here's an example ： if you have a $ 20,000 loan, with a 4.2% interest, rate, you will end up paying an extra $ 2,814in interest alone over six and a half years. If you increase your payment by only $ 50 a month, you'll cut that interestby $ 500 ; ff you can find a way to pay $ I00 more a month, you'll save nearly $ 800 in interest. That's $ 800 more inthe bank, and $ 800 less wanted on pointless interest payments.Take it in stride[R]Most Americans owe some form of debt; learning how to handle it is a lifelong process. Most of all, don't beat yourself up if you're not perfect at paying down your loans. Some of the savviest financial players struggled for years with their own finances. We all learn in our own time and we rind what works for us and what doesn't. Accept your own progress.46.If you have a federal loan, you are allowed to pay back the loan later when you are fired.47.LearaVest informs you about your spending so that you can see where to save money to pay off your debt.48.Even for financial experts, financial problems may have taken them years to deal with.49.You are advised to start with the loans with thehigher interest rate.50.Many Americans are in debt and learning how to handle itwill take a lifetime.51.With Google Docs spreadsheet, you can create yourown personalized debt graphs.52.If you don't have enough income, you are advised totry other ways of making money.53.Those student, loan providers' websites don't present thegrowth of your debt load.54.The result of inaction to your loans is to bringabout bigger loans.55.When you toss away envelopes containing your bills,you actually feel more anxious about it.46．If you have a federal loan ．you are allowed to pay back the loan later when you are fired ．详解如果你有联邦贷款，能够在失业时延期还款。

2019年12月英语六级长篇阅读匹配练习题（2）Protecting Student Privacy in the Data AgeA． In Kentucky, parents, educators and policy makerscan track how many students from a high school go to college, and once they are there, how many require remedial classes(补习班) ． Massachusetts is one of several states with an early warning indicator system, which notifies schoolofficials when students appear to be at risk for dropping out of high school． And in Georgia, teachers can easily access years of test scores, class, grades and attendance rates for any student．B． Student data advocates argue that used correctly data，including student attendance, test scores and demographics(人口统计) , can enrich education． Teachers can better personalize instruction for students, principals can view the academic records of students who move across school districts and parents can determine whether a child is on track for college, to name just a few examples．C． But that promise comes with threats to students" privacy． Parents have expressed concerns that if teachers have easy access to students' entire academic histories, they might write off those with poor records, or that student information might fall into the hands of sexual predators (侵害者) ． Those concerns have led to heated debates about how much data schools should be collecting, how it should bestored and who should have access to it．D． Over the past year, the Common Core State Standards have also triggered discussions about student data, althoughthe standards do not call for the federal government to collect data． "There's no denying that education technology has the potential to transform learning if it's used wisely," said Joni Lupovitz, vice president of policy at Common Sense Media, which this fall launched a campaign to raise awareness about student privacy issues． "What we're working to ensure is that as educators, parents and student embrace more and more education technology, (and)balance the equation by focusing on student privacy to help ensure that we're creating an atmosphere where kids can learn and be engaged and thrive without putting their personal information at risk．"Relying on a 1970s LawE． Until recently, most states weighing privacy questions relied on the federal Family Educational Rights and Privacy Act (FERPA) , a 1974 law intended to protect student education records, But in recent years, the U．S． Department of Education has made regulatory changes to the law, creating many exceptions． For example, education records now may be shared with outside contractors, such as private companies that track grades or attendance on behalf of school systems． The changes have prompted some states to examine whether they should play a stronger role in protecting student data．F． Paige Kowalski, director of state policy and advocacy for the Data Quality Campaign, a nonprofit that advocates for the effective use of data to improve student achievement, said states are starting to realize they need more sophisticated and comprehensive policies, regulations andpractices around student privacy, and that they can't just rely on FERPA．G． "All states have privacy laws on the books, but a lot of them are old," Kowalski said． "A lot of them just don't have modern policies that were written acknowledging that data is even at the state level, let alone stored electronically and because of technology is able to move．" Kowalski added that states' privacy policies might refer to outdated information practices, such as checking out paper documents, while failing to discuss modern needs like encryption (加密)．H． Most school districts rely on cloud computing--meaning data are stored on servers that can be accessed through the Internet--for everything from cafeteria payments to attendance records． But a recent study by the Center on Law and Information Policy at Fordham Law School concluded that most cloud-based services are "poorly understood, nontransparent and weakly governed" by schools． Most school districts fail to inform parents that they are using cloud-based services, and many contracts with web-based vendors (供应商) fail to address privacy issues, the study found．Keeping Parents in the DarkI． The Electronic Privacy Information Center, anonprofit research group in Washington, D．C．, filed a lawsuit in February 2012 against the U．S． Department of Education challenging its FERPA changes, but a federal court dismissed the lawsuit for lack of standing．。

英语六级阅读段落匹配练习题及答案英语六级阅读段落匹配练习题原文How to Make Attractive and Effective PowerPoint PresentationsA) Microsoft PowerPoint has dramatically changed the way in which academic and business presentations are made. This article outlines few tips on making more effective and attractive PowerPoint presentations.The TextB) Keep the wording clear and simple. Use active, visual language. Cut unnecessary words—a good rule of thumb is to cut paragraphs down to sentences, sentences into phrases, and phrases into key words.Limit the number of words and lines per slide. Try the Rule of Five-five words per line, five lines per slide. If too much text appears on one slide, use the AutoFit feature to split it between two slides. Click within the placeholder to display the AutoFit Options button (its symbol is two horizontal lines with arrows above and below), then click on the button and choose Split Text between Two Slides from the submenu.C) Font size for titles should be at least 36 to 40, while the text body should not be smaller than e only two font styles per slide —one for the title and the other for the text. Choose two fonts that visually contrast with each other. Garamond Medium Condensed and Impactare good for titles, while Garamond or Tempus Sans can be used for the text body.D) Embed the fonts in your presentation, if you are not sure whether the fonts used in the presentation are present in the computer that will be used for the presentation. To embed the fonts: (1) On the File menu, click Save As. (2) On the toolbar, click Tools, click Save Options, select the Embed TrueType Fonts check box, and then select Embed characters in use only.E) Use colors sparingly; two to three at most. You may use one color for all the titles and another for the text body. Be consistent from slide to slide. Choose a font color that contrasts well with the background.F) Capitalizing the first letter of each word is good for the title of slides and suggests a more formal situation than having just the first letter of the first word capitalized. In bullet point lines, capitalize the first word and no other words unless they normally appear capped. Upper and lower case lettering is more readable than all capital letters. Moreover, current styles indicate that using all capital letters means you are shouting. If you have text that is in the wrong case, select the text, and then click Shift+F3 until it changes to the case style that you like. Clicking Shift+F3 toggles the text case between ALL CAPS, lower case, and Initial Capital styles.G) Use bold or italic typeface for emphasis. Avoid underlining, it clutters up the presentation.Dont center bulleted lists or text. It is confusing to read. Left align unless you have a good reason not to. Run “spell check” on your show when finished.The BackgroundH) Keep the background consistent. Simple, light textured backgrounds work well. Complicated textures make the content hard to read. If you are planning to use many clips in your slides, select a white background. If the venue of your presentation is not adequately light-proof, select a dark-colored background and use any light color for text. Minimize the use of “bells and whistles” such as sound effects, “flying words” and multiple transitions. Dont use red in any fonts or backgrounds. It is an emotionally overwhelming color that is difficult to see and read.The ClipsI) Animations are best used subtly; too much flash and motion can distract and annoy viewers. Do not rely too heavily on those images that were originally loaded on your computer with the rest of Office. You can easily find appropriate clips on any topic through Google Images. While searching for images, do not use long search phrases as is usually done while searching the web-use specific words.J) When importing pictures, make sure that they are smaller than two megabytes and are in a .jpg format. Larger files can slow down your show. Keep graphs, charts and diagrams simple, if possible. Use bar graphs and pie charts instead of tables of data. The audience can then immediately pick up the relationships.The PresentationK) If you want your presentation to directly open in the slide show view, save it as a slide show file using the following steps. Open the presentation you want to save as a slide show. On the File menu, clickSave As. In the Save as type list, click PowerPoint Show. Your slide show file will be saved with a ppt file extension. When you double-click on this file, it will automatically start your presentation in slide show view. When youre done, PowerPoint automatically closes and you return to the desktop. If you want to edit the slide show file, you can always open it from PowerPoint by clicking Open on the File menu.L) Look at the audience, not at the slides, whenever possible. If using a laser pointer, dont move it too fast. For example, if circling a number on the slide, do it slowly. Never point the laser at the audience. Black out the screen (use “B” on the keyboard) after the point has been made, to put the focus on you. Press the key again to continue your presentation.M) You can use the shortcut command [Ctrl]P to access the Pen tool during a slide show. Click with your mouse and drag to use the Pen tool to draw during your slide show. To erase everything youve drawn, press the E key. To turn off the Pen tool, press [Esc] once.MiscellaneousN) Master Slide Set-Up: The “master slide” will allow you to make changes that are reflected on every slide in your presentation. You can change fonts, colors, backgrounds, headers, and footers at the “master slide” level. First, go to the “View” menu. Pull down the “Master”menu. Select the “slide master” menu. You may now make changes at this level that meet your presentation needs.英语六级阅读段落匹配练习题目1. The ways in which academic and business presentations are made have been changed by Microsoft PowerPoint.2.

2019年12月英语六级长篇阅读匹配练习题（4） Apps Designed for Distracted DriversA． Marry Williams recalls the conversations he and his wife would have with their two daughters about the dangers of talking and texting while driving．．"It's always a concern," said Williams． "We just drilled it into their heads over and over until they said 'Okay, we get it,' and when we saw something [about the dangers of drivers texting] on TV we made sure they saw it, too．"B． Parents like Williams have good reason toworry． Half of teens say they tall on a cell phone while driving, a third say they swap text messages, and almost half say they've been a passenger in a vehicle with a teen driver whose phone use put them at risk, according to federal statistics． Teen drivers are more likely to get into a fatal crash than anyone under the age of 80, in part because their brains are still developing the system that evaluates risk．C． These days, however, there's an app for that, several of them, in fact． There are apps that prevent mobile-device use while driving, and some of them alert parents or employers when a user tries to beat the system．They've emerged on the market as alarm grows over the carnage caused by distracted driving．D． More than 3,300 people die and 420,000 are injured annually in crashes attributed to distracted drivers． But those numbers may be low because, other than a driver's admission of fault, it's a challenge to prove thatdistraction caused a crash． Among all drivers involved infatal crashes, teens were the most likely to have been distracted, National Highway Traffic Administration data show． "They feel invincible," said Jurek Grabowski, director of research at the AAA Foundation for Traffic Safety． "They have large social networks and they want to stay in contact with them．"E． Conversations on the go, texting, surfing theInternet and taking selfies (自拍) are such a habit among teens that studies show they underestimate the risk． Teens make up a significant percentage of the approximately 660,000 drivers who are having phone conversations or manipulating electronic devices while driving at any given moment during daylight hours in the United States． And most teenagers who chat, text or surf while driving are breaking the law． The District and 37 states--including Maryland and Virginia--ban novice drivers from talking on the phone while driving． The three local jurisdictions (管辖区) and 41 other states barall drivers from sending and receiving text messages while driving． But respect for those laws is similar to that given the speed limit．F． "We need to almost turn this thing into a brick," David Coleman said recently, holding up his cell phone while sitting in a Bowie Starbucks． "It can't just be about texting． It has to be about e-mail, Facebook and no inappropriate calls．" Coleman is marketing director for Louisiana-based Cellcontrol, one of several companies competing for the chance to shut down people's mobile devices while they're driving． Most of the companies that sell cell phone service--Verizon, AT&T, Sprint and others--also provide apps that can limit access．G． Many of the apps are triggered when a GPS sensor detects that a vehicle is in motion, and some—such as AT&T's DriveMode---will alert parents or employers when the app has been turned off or disabled．Independent experts considerthat a feature buyers should look for． "Especially for younger drivers． As clever as you can be, they will be more clever," said Leo McCloskey, a tech specialist for the Intelligent Transportation Society of America． "The best way to do it is to integrate the device with the vehicle so that you could have more precise control．"H． That precise control means that parents or employers can select the features they want to allow their drivers to use and block those that worry them． "It's important to have a solid oversight function so that use can be monitored by a fleet (车队) manager or parent," said Russ Rader of the Insurance Institute for Highway Safety． "Cellcontrol is one of the better, most complete systems． TeenSafer is another one that we've looked at that works pretty well．．These products are going to be the most useful for fleet operators and for parents trying to control phone use by their driving teens． Both Cellcontrol and TeenSafer will report attempts to disrupt the system．"I． Businesses that send fleets of cars, vans or trucks onto the streets have shown increasing interest in those products, as juries have issued multimillion-dollar rewards to those injured or killed by distracted drivers who were on the job．J． Systems integrated into the vehicle are triggered when the car or truck begins to move． "We're not guessingbased on a satellite, we're depending on the vehicle to tell us," said Cellcontrol's Coleman as he spent a morning demonstrating his company's product in Prince George's County． "Otherwise, how do I know you're not on a Greyhound bus or on a plane that has landed and is taxiing (滑行) to the gate?"K． Cellcontrol provides two options for connecting to a vehicle． One is a device the size of an E-Zpass transponder (电子收费应答器) that is glued to the windshield with the same adhesive material used to secure rearview mirrors． The more sophisticated choice plugs in to a vehicle's diagnostic computer port． The $129-system works with iPhones, Androids, BlackBerrys and Windows Mobile．L． The system involves an app that is downloaded to the phone of the driver--teenager or employee． The key to the system is software that can be installed on a home computer, tablet or mobile device that allows an authorized person--parent or boss--to customize what the driver is permitted to do, and to monitor compliance (遵从)． "We're not blocking the signal, we're allowing a protective policy to be brought into the device," he said． "The administrator has the option to make the policy as restrictive as possible, or not．" For example, phone use could be restricted to a hands-free device． Or calls could be restricted to an emergency number or a parent or office． Or parents could attempt to mandate (命令) that all passengers in the car driven by their teenager download the app． "You could decide this is the kids' car and we don't want a stupid sitting in the passenger's seat showing the driver YouTube videos," Coleman said．M． Coleman demonstrated how his phone was pre-programmed to go into safe mode when he drove, but when handed to a passenger it was fully operative． A second phone he brought along went into safe mode when the car was moving, regardless of whether it was in his hands or those of apassenger． Acknowledging that parents are dealing with a technology-savvy (精通科技的) generation and that employers exist in a technologically smart world, Coleman said, "We've built in some traps and fail-safes (故障安全装置) to notifythe parent or employer．"N． McCloskey said that companies like Cellcontrol that provide integrated services are "where we need to go．" "The operating system of the phone itself can interact with the operating system of the vehicle in such a way that services can be authorized, services can be presented, and servicescan be consumed all in a safe and predictable manner," McCloskey said．O． Although he is concerned about distracted driving, McCloskey thinks it as a relatively short-term problem．"Inthe medium to long term, as autonomous vehicles really start making a mark, all this goes away as a concern," he said．46． The deaths and injuries caused by distracted drivingmay be underestimated due to the difficulty to identify the role of distraction in an accident．47． McCloskey believes that distracted driving will nolonger be a problem with the emergence of autonomous vehicles．48． Williams made every effort to raise his teens' awareness about the danger of phone use while driving．49． Cellcontrol is recommended as one of the best systems available for those parents who worry about the safety oftheir driving teens．50． Cellcontrol makes it possible that parents control the phone use of the passengers when their child's is the driver．51． The laws in many parts of the US restrict phone usewhile driving, which are nevertheless poorly observed in practice．52． Coleman demonstrated his company's product with two cell phones functioning in different ways．53． Statistics show that phone use is a common phenomenon among teen drivers, which may lead to deadly traffic accidents．54． Some companies suffered a huge economic loss due totheir employees' distracted driving．55． The system of Cellcontrol can be integrated into avehicle in two different ways．。

2019英语六级长篇阅读匹配练习题及答案(五)Section B[A] We apply for credit for many reasons-maybe it's to buy a new car, house, computer, or get a student loan. However, that there is a special number that can determine whether you can do these things, or at least how much it will cost you. A credit score is a number that is calculated based on your credit history to give lenders a simpler "lend/don't lend" answer for people who are applying for credit or loans. This number helps the lender identify the level of risk they may be taking if they lend to someone. The credit score is quicker and less subjective. It's the credit score that makes it possible to get instant credit at places like electronics stores and department stores.[B] Although there are several scoring methods, the method most commonly used by lenders is known as a FICO because of its origins with Fair Isaac Corporation. Fair Isaac is an independent company that came up with the scoring method and software used by banks and lenders, insurers and other businesses. Each of the three major credit bureaus (Experian, Equifax and TransUnion) worked with Fair Isaac in the early 1980's to come up with the scoring method.[C] The three national credit bureaus each have their own version of the FICO score with their own names. Equifax has the Beacon system, TransUnion has the Empirica system, and Experian has the Experian/Falr Isaac system. Each is based on the original Fair Isaac FICO scoring method and produces equivalent numerical results for any given creditreport. Some lenders also have their own scoring methods. Other scoring methods may include information such as your income or how long you've been at the same job.[D] Think of your credit score, like your grade in school. A teacher calculates grades by taking scores from tests, homework, attendance and anything else they want to use, weighting each one according to importance in order to come up with a final single number (or letter)score. Yourcredit score is calculated in a very similar manner. Insteadof using the scores from pop quizzes and reports you wrote,it uses the information in your credit report.[E] 35 percent of the score is based on your payment history. This makes sense since one of the primary reasons a lender wants to see the score is to find out if (and how timely)you pay your bills. The score is affected by how many bills have been paid late, how many were sent out for collection, any bankruptcies, etc. When these things happened also comes into play. The more recent, the worse it will befor your overall score.[F] 30 percent of the score is based on outstanding debt. How much do you owe on car or home loans? How many creditcards do you have that are at their credit limits? The more cards you have at their limits, the lower your score will be. The rule of thumb is to keep your card balances at 25% orless of their limits.[G] 15 percent of the score is based on the length oftime you've had credit. The longer you've had established credit, the better it is for your overall credit score. Why?Because more information about your past payment history gives a more accurate prediction of your future actions.[H] 10 percent of the score is based on the number of inquiries on your report. If you've applied for a lot of credit cards or loans, you will have a lot of inquiries on your credit report. These are bad for your score because they indicate that you may be in some kind of financial trouble or may be taking on a lot of debt (even if you haven't used the cards or gotten the loans). The more recent these inquiries are, the worse for your credit score. FICO scores only count inquiries from the past years.[I] 10 percent of the score is based on the types of credit you currently have. The number of loans and available credit from credit cards you have makes a difference. Thereis no magic number or combination of types of accounts that you shouldn't have. These actually come more into play if there isn't as much other information on your credit report on which to base the score. This information is compared to the credit performance of other consumers with similar histories and profiles.[J] Your credit score doesn't just affect whether or not you get a loan; it also affects how much that loan is going to cost you. As your credit score increases, your credit risk decreases. This means your interest rate decreases. There are other factors that influence the interest rate you get for a loan besides your credit score. Things like the type of property you are using the loan to buy, how much of your own money is going into it, the costs the lender has to make the loan, etc.。

2019大学英语六级长篇阅读匹配练习题(4)Does the Internet Make You Dumber?[A] The Roman philosopher Seneca may have put it best 2,000 years ago： "To be everywhere is to be nowhere." Today, the Internet grants us easy access to unprecedented amounts of information. But a growing body of scientific evidence suggests that the Net, with its constant distractions and interruptions, is also turning us into disrupted and superficial thinkers.[B] The picture emerging from the research is deeply troubling, at least to anyone who values the depth, rather than just the velocity (速度), of human thought. People who read text studded with links, the studies show, comprehend less than those who read traditional linear text. People who watch busy multimedia presentations remember less than those who take in information in a more sedate (镇定的) and focused manner. People who are continually distracted by e-mails, alerts and other messages understand less than those who are able to concentrate. And people who juggle (尽力同时应付)many tasks are less creative and less productive than those who do one thing at a time.[C] The common thread in these disabilities is dispersing our attention. The richness of our thoughts, our memories and even our personalities hinges on our ability to focus the mind and sustain concentration. Only when we pay deep attention to a new piece of information are we able to associate it "meaningfully and systematically with knowledge already well established in memory," writes the Nobel Prizewinning neuroscientist (神经科学家) Eric Kandel. Such associations are essential to mastering complex concepts.[D] When we're constantly distracted and interrupted, as we tend to be online, our brains are unable to generalize the strong and expansive neural connections that give depth and distinctiveness to our contemplating. We become mere signal-processing units, quickly shepherding disjointed bits of information into and then out of short-term memory.[E] In an article published in Science last year, Patricia Greenfield, a leading developmental psychologist, reviewed dozens of studies on how different media technologies influence our cognitive abilities. Some of the studies indicated that certain computer tasks, like playing video games, can enhance" visual literacy skills", increasing the speed at which people can shift their focus among icons and other images on screens. Other studies, however, found that such rapid shifts in focus, even if performed adeptly, result in less rigorous and "more automatic" thinking.[F] In one experiment conducted at Cornell University, for example, half a class of students was allowed to use Internet-connected laptops during a lecture, while the other had to keep their computers shut. Those who browsed the Web performed much worse on a subsequent test of how well they retained the lecture's content. While it's hardly surprising that Web surfing would distract students, it should be a note of caution to schools that are wiring their classrooms in hopes of improving learning.[G] Ms. Greenfield concluded that "every medium develops some cognitive skills at the expense of others. " Our growinguse of screen-based media, she said, has strengthened visual-spatial intelligence, which can improve the ability to dojobs that involve keeping track of lots of simultaneous signals, like air traffic control. But that has been accompanied by "new weaknesses in higher-order cognitive processes," including "abstract vocabulary, mindfulness, reflection, inductive problem solving, critical thinking, and imagination." We're becoming, in a word, shallower.[H] In another experiment, recently conducted atStanford University's Communication between Humans and Interactive Media Lab, a team of researchers gave various cognitive tests to 49 people who do a lot of mediamultitasking and 52 people who multitask much less frequently. The heavy multitaskers performed poorly on all the tests.They were more easily distracted, had less control over their attention, and were much less able to distinguish important information from trivial.[I] The researchers were surprised by the results. They had expected that the intensive multitaskers would havegained some unique mental advantages from all their on-screen juggling. But that wasn't the case. In fact, the heavy multitaskers weren't even good at multitasking. They were considerably less adept at switching between tasks than the more infrequent multitaskers. "Everything distracts them," observed Clifford Nass, the professor who heads the Stanford lab.[J] It would be one thing if the ill effects went awayas soon as we turned off our computers and cell phones. But they don't. The cellular structure of the human brain,scientists have discovered, adapts readily to the tools we use, including those for finding, storing and sharing information. By changing our habits of mind, each new technology strengthens certain neural pathways and weakens others. The cellular alterations continue to shape the way we think even when we're not using the technology.[K] The pioneering neuroscientist Michael Merzenich believes our brains are being "massively remodeled" by our ever-intensifying use of the Web and related media. In the 1970s and 1980s, Mr. Merzenich, now a professor emeritus at the University of California in San Francisco, conducted a famous series of experiments on primate brains that revealed how extensively and quickly neural circuits change in response to experience. When, for example, Mr. Merzenich rearranged the nerves in a monkey's hand, the nerve cells in the animal's sensory cortex quickly reorganized themselves to create a new" mental map" of the hand. In a conversation late last year, he said that he was profoundly worried about the cognitive consequences of the constant distractions and interruptions the Internet bombards us with. The long-term effect on the quality of our intellectual lives, he said, could be "deadly".[L] What we seem to be sacrificing in all our surfing and searching is our capacity to engage in the quieter, attentive modes of thought that underpin contemplation, reflection and introspection. The Web never encourages us to slow down. It keeps us in a state of perpetual mental locomotion. It is revealing, and distressing, to compare the cognitive effects of the Internet with those of an earlier information technology, the printed book. Whereas theInternet scatters our attention, the book focuses it. Unlike the screen, the page promotes contemplativeness.[M] Reading a long sequence of pages helps us develop a rare kind of mental discipline. The innate bias of the human brain, after all, is to be distracted. Our predisposition isto be aware of as much of what's going on around us as possible. Our fast-paced, reflexive shifts in focus were once crucial to our survival. They reduced the odds that apredator would take us by surprise or that we'd overlook a nearby source of food.[N] To read a book is to practice an unnatural processof thought. It requires us to place ourselves at what T. S. Eliot, in his poem "Four Quartets", called "the still pointof the turning world". We have to forge or strengthen the neural links needed to counter our instinctive distractedness, there by gaining greater control over our attention and our mind.[O] It is this control, this mental discipline, which we are at risk of losing as we spend ever more time scanning and skimming online. If the slow progression of words across printed pages damped our craving to be inundated by mental stimulation, the Internet indulges it. It returns us to our native state of distractedness, while presenting us with far more distractions than our ancestors ever had to contend with. -Nicholas Carr is the author, most recently, of "The Shallows：What the Internet Is Doing to Our Brains".46. Rapid shifts in focus on screens during computertasks can cause more automatic but less intensive thoughts.47. People get less understanding from the texts filled with Internet links than normal reading.48. According to Ms. Greenfield, growing use of screen-based media has improved our visual-spatial intelligence.49. The richness of our memories relies on our abilityto focus on something.50. Unprecedented amounts of information can make our thoughts scattered.51. When we turn off our computers and cellphones, theill effects will not disappear.52. When we are online, our brains cannot formdistinctive and profound thinking.53. Whereas the Internet distracts our attention, the book concentrates on it.54. The experiment conducted at Cornell University indicates web surfing to school would distract students' thoughts.55. According to the experiment at Stanford University, the multitaskers' attention was easily scattered.46. 译文：电脑屏幕上注意力焦点的迅速转移使人们的思维变得更加机械，而不那么严谨了。
