2019年12月大学英语四级考试阅读讲义(四十二)Unit 15Part Ⅱ Reading Comprehension(35 minutes)Directions： There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a singleline through the centre.考试大Questions 21 to 25 are based on the following passage：We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist(免疫学家) Mark Laudenslager, at the Universityof Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel intheir enclosure, while the other half could not. The rats in the two groups were paired so that each time one rat turnedthe wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don't develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists' suspicions that the experience or perception of helplessness is one of the most harmful factors in depression. One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the University of Rochester School of Medicine conditioned(使形成条件反射) mice to avoid saccharin(糖精) by simultaneously feeding them the sweetener and injecting them with a drugthat while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlierconditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.21. Laudenslager's experiment showed that the immune system of those rats who could turn off the electricity .A) was alteredB) was strengthenedC) was weakenedD) was not affected22. According to the passage, the experience of helplessness causes rats to .A) turn off the electricityB) try to control unpleasant stimuliC) become abnormally suspiciousD) behave passively in controllable situations23. The reason why the mice in Ader's experiment avoided saccharin was that.A) they associated it with stomachachesB) it affected their immune systemsC) it led to stomach painsD) they disliked its taste24. The passage tells us that the most probable reason for the death of the mice in Ader's experiment was that .A) the sweetener was poisonous to themB) their immune systems had been altered by the mindC) they had been weakened psychologically by the saccharinD) they had taken too much sweetener during earlier conditioning25. It can be concluded from the passage that the immune systems of animals .A) can be altered by electric shocksB) can be weakened by conditioningC) can be suppressed by drug injectionsD) can be affected by frequent doses of saccharin。

Each paragraph is markedwith a letter: Answer the questions by marking the corresponding letteron Answer Sheet 2.The Quiet Heroism of Mail Delivery'·[A] On Wednesday, a polar wind brought bitter cold to the Midwest. Overnight,Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colderthan Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zeroin Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Dakota,according to the National Weather Service. Schools, restaurants, and businessesclosed, and more than l ,000 flights have been canceled.[B] Even the United States Postal Service (USPS) suspended mail deliverytemporarily. "Due to this arctic outbreak and concerns for the safety of USPSemployees," USPS announced Wednesday morning, the Postal Service is suspendingdelivery Jan. 30 in the following 3-digit ZIP Code locations." Twelve regions werelisted as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extremeweather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and othernatural disasters cost at least $49 billion in the United States. As my colleague VannNewkirk reported, Puerto Rico is still confronting economic and structural destructionand resource scarcity from 2017's Hurricane Maria. Natural disasters can wreck acommunity's infrastructure, disrupting systems for months or years. Some services,however, remind us that life will eventually return, in some form, to normal,[D] Days after the deadly 2017 wildfires in Santa Rosa, California, a dronecaught footage of a USPS worker, Trevor Smith, driving through burned homes in thatfamiliar white van, collecting mail in an affected area. The video is striking: The operation is familiar, but the scene looks like the end of the world. According to RaeAnn Haight, the program manager for the national-preparedness office at USPS,Smith was fulfilling a request made by some of the home owners to pick up any mailthat was left untouched. For Smith, this was just another day on the job. I followedmy route like I normally do," Smith told a reporter. As I'd come across a box thatwas up but with no house, I checked, and there was mail--outgoing mail--in it. Andso we picked those up and carried on.'[E] USPS has sophisticated emergency plans for natural disasters. Across thcountry, 285 emergency-management teams are devoted to crisis control. These teamsare trained annually using a framework known as the three Ps: people, property,product. After mail service stops due to weather, the agency 's top priority is ensuringthat employees are safe. Then it evaluates the health of infrastructure, such as theroads that mail carriers drive on. Finally, it decides when and how tore-openoperations. If the destruction is extreme, mail addressed to the area will get sentelsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming NewOrleans mail to existing mail facilities in Houston. Mail that was already processed inNew Orleans facilities was moved to an upper floor so it would be protected fromwater damage.[F] As soon as it's safe enough to be outside,' couriers start distributingaccumulated mail on the still-accessible routes. USPS urges those without standingaddresses to file change-of- address forms with their new location. After HurricaneKatrina hit in 2005, mail facilities were set up in dozens of other locations across thecountry in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, 493.4 million pieces ofmail -anything from postcards to Social Security checks to medicine. Spokespeoplefrom both USPS and UPS told me all mail is important. But some mail can beextremely sensitive and timely. According to data released in January 2017, 56percent of bills are paid online, which means that just under half of payments still relyon delivery services to be completed.[H] It can be hard to identify which parcels are carrying crucial items such asSocial Security checks, but USPS and UPS try their best to prioritize sensitivematerial. They will coordinate with the Social Security Administration to make surethat Social Security checks reach the right people in a timely fashion. After HurricaneFlorence and Hurricane Michael last fall, USPS worked with state and local electionboards to make sure that absentee ballots were available and received on time.[I] Mail companies are logistics companies, which puts them in a special positionto help when disaster strikes. In a 2011 USPS case study, the agency emphasized itsmassive infrastructure as a unique federal asset" to be called upon in a disaster orterrorist attack. I think we're unique as a federal agency," USPS official MikeSwigart told me, because we're in literally every community in this countryWe' re obligated to deliver to that point on a daily basis.'[J] Private courier companies, which have more dollars to spend, use theirexpertise in logistics to help revitalize damaged areas after a disaster. For more than adecade, FedEx has supported the American Red Cross in its effort to get emergencysupplies to areas affected by disasters, both domestically and internationally. In 2012,the company distributed more than 1,200 MedPacks to Medical Reserve Corps groupsin California, and donated space for 3.1 million pounds of charitable shipping st October, the company pledged $1 million in cash and transportation support forHurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, usesthe company 's logistics to help disaster-struck areas rebuild. We realize that as acompany with people, trucks, warehouses, we needed to play a larger role," saidEduardo Martinez, the president of the UPS Foundation. The company employs it:trucks and planes to deliver food, medicine, and water. The day before I spoke toMartinez in November, he had been touring the damage fromHurricane Michael inFlorida with the American Red Cross. We have an obligation to make sure ourcommunities are thriving, prosperous," he said.[K] Rebuilding can take a long time, and even then, impressions of the disastermay still remain. Returning to a sense of normalcy can be difficult, but some smallroutines--mail delivery being one of them--may help residents remember that theircommunities are still their communities. When they see that carrier back out on thestreet," Swigart said, that's the first sign to them that life is starting to return tonormal."36. The United States Postal Service has a system to ensure its employees' safety.37. One official says USPS is unique in that it has more direct reach tccommunities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half ofpayments.40. The sight of a mailman on the street is a reassuring sign of life becomingnormal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail servicepoints were set up.42. Postal service in some regions in the U.S. was suspended due to extreme coldweather.43. Private postal companies also support disaster relief efforts by distributingurgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite ofextreme conditions.45. Postal services work hard to identify items that require priority treatment. Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are fourchoices marked A), B), C) and D). You should decide on the best choiceand mark the corresponding letter on Answer Sheet 2 with a single line 'through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligentteaching assistant to help handle the enormous number of student questions in theonline class, Knowledge Based Artificial Intelligence. This online course is a corerequirement of Georgia Tech's online Master of Science in Computer Scienceprogram. Professor Goel already had 8 teaching assistants, but that wasn t enough todeal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching support.When students feel isolated or confused and reach out with questions that gounanswered, their motivation to continue begins to fade. Professor Goel decided to dosomething to remedy this situation and his solution was to create a virtual assistantnamed Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill W atson before releasing herto the online forums. At first, the virtual assistant wasnt too great. But Goel and histeam sourced the online discussion forum to find all 40,000 questions that had everbeen asked since the class was launched. Then they began to feed Jill the questionsand answers. After some adjustment and sufficient time, Jill was able to answer thestudents questions correctly 97% of the time. The L virtual assistant became soadvanced and realistic that the students didn t know she was a computer. The students,who were studying artificial intelligence, were interacting with artificial intelligenceand couldn't tell it apart from a real human being. Goel didn 't inform them about Jill'strue identity until April 26. The students were actually very positive about theexperience.The goal of Professor Goel's virtual assistant next year is to take over answering40% of all questions posed by students on the online forum. The name, Jill Watson,will of course, change to something else next semester. Professor Goel has a muchrosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gatesor Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence?A) It is a robot that can answer students' questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet with?A) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students questions were too many to handle.D) Too many students dropped out of his course.48. What do we learn about Jill Watson?A) She turned out to be a great success.B) She got along pretty well with students.C) She was unwelcome to students at first.D) She was released online as an experiment.10/23149. How did the students feel about Jill W atson?A) They thought she was a bit too artificial.B) They found her not as capable as expected.C) They could not but admire her knowledge.D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill W atson?A) Launch different versions of her online.B) Feed her with new questions and answers.c) Assign her to answer more of students questions.D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don' t hurt. Thoseare a few of the traits of successful science crowdfunding efforts that emerge from arecent study that examined nearly 400 campaigns. But having a large network andsome promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken offin recent years for everything from making movies to building water-saving gadgets.Scientists have tried to tap Internet donors, too, with mixed success. Some raisedmore than twice their goal, but others have fallen short of reaching more modesttargets.To determine what separates science crowdfunding triumphs from failures, ateam led by science communications scholar Mike Schäfer of the University of Zurichin Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report inPublic Understanding of Science. For one, they use a crowdfunding platform thatspecializes in raising money for science, and not just any kind of project. Althoughsites like Kickstarter take all comers, platforms such as Experiment.com,, and Petridish. org only present scientific projects. For another, theypresent the project with a funny video because good visuals and a sense of humorimproved success. Most of them engage with potential donors since projects thatanswered questions from interested donors and posted lab notes fared better. And theytarget a small amount of money. The projects included in the study raised $4000 onaverage, with 30% of projects receiving less than $ 1000. The more money a projectsought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project's success, most notably,the size of a scientist's personal and professional networks, and how muchresearcher promotes a project on his or her own. Those two factors are by far morecritical than the content on the page. Crowdfunding can be part of researchers effortsto reach the public, and people give because they feel a connection to the person"who is doing the fundraising--not necessarily to the science.11/3151. What do we learn about the scientists trying to raise money online for theirprojects?A) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schafer's research of recent crowdfundingcampaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations.为B) Its interaction with prospective donors.C) Its originality in addressing financial issues.D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfundingprojects?A) They should be small to be successful.B) They should be based on actual needs.C) They should be assessed with great care.D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part IV Translation (30 minutes) Directions: For this part, you cre allowed 30 minutes to translate a passage from ( 'hinese into English.

但是这些障碍正在逐渐消除,部分原因是全球的期刊和基金机构正在鼓励科学家将其研究数据公开。去年,伦敦皇家学会在其报告中表示,科学家需要“ 扭转数据被视为私人专利的研究风气”。基金机构注意到,用公共资金支付的数据应该是公共信息,科学界正在认识到,现在可以以前所未有的数字化方式共享数据。为满足日益增长的需求,各种服务迅速发展,使得在线发布研究成果更容易,并使其他研究人员能够发现和引用它们。
B) benefits sharers and users alike
C) makes researchers successful
D) saves both money and labor
3. C) 。推断题。根据题干中的 hinder 初步定位在第三段第一句,But the barriers are disappearing 中 barriers 和 hinder 意义相同, 都为 “阻碍”之意。因此我们把问题往下定位在第三段第二句,这句话主要讲了科学家需要 “ 扭转数据被视为私人专利的研究风气” ,因此推断出阻碍数据共享的原因是科学家把数据视为私人专利, 因此选项 C) 是正确答案。
1
��
3. According to the passage, what might hinder open data sharing? A) The fear of massive copying. B) The lack of a research culture. C) The belief that research data is private intellectual property. D) The concern that certain agencies may make a profit out of it.

2019年12月英语四级考试A卷答案权威精析与解题思路

2019年12月英语四级考试A卷答案权威精析与解题思路大家网阮景林深度阅读Section A47. F/ desireNatural为形容词，它修饰的应是名词。

而动词Meet可以让人想到meet one’s desire这个词组，意思为满足某人的欲望。

这样，填入名词desire，句意就是书能满足对自由的自然渴望，合情合理。

48. K/ naturallyTurn to为动词短语，意思是“转向……”出现在两个词之间的必然为副词，修饰turn。

在D、K、M三个副词中，naturally最为合适。

句意为人们因为好奇心而自然地诉求于书。

49. H/ escape句意应该是读者很想从有限的自我空间中解脱出来。

To可以判断为动词不定式的标志，所以to后面应该是动词原形，可选的动词中escape（逃离）较为合适，它与from搭配表示“从……逃离”。

50. G/ diversityA为冠词，其后必然为名词，余下的选项中diversity是各种各样的意思，characters是人物，personnel为人事。

再看句意。

上一句讲到书使人熟悉过去世界和现在世界的生活，本句继续说读书的人们的面前呈现了人类经验。

填入diversity，表示各种各样的经验，与上文的世界生活相照应。

51. N/ respectTo后面显然要选用动词原形，仅剩的动词原形有derive、respect、narrow、widen，根据上文的意思，本句大意应该是了解其他思维与生活方式，首先可以排除narrow和widen，因为人们只能对自己的生活施以影响，是不能缩小或扩大“其他”人的思想和生活的。

Narrow和widen同时出现，很可能互为干扰项，也就是在其他填空中这二者为最有可能的选项，所以在本空可以一起排除。

Derive有获取、得到的意思，respect为尊重、看重，填入文中似乎都说得过去，而respect更为合适些。

2019年12月大学英语四级考试阅读讲义(四十八)

2019年12月大学英语四级考试阅读讲义(四十八)Unit 21Part II Reading Comprehension(35 minutes)Directions： There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a singleline through the centre.Passage OneQuestions 21 to 25 are based on the following passage.When global warming finally came, it stuck with a vengeance(异乎寻常地). In some regions, temperatures rose several degrees in less than a century. Sea levels shot up nearly 400 feet, flooding coastal settlements and forcing people to migrate inland. Deserts spread throughout the world as vegetation shifted drastically in North America, Europeand Asia. After driving many of the animals around them to near extinction, people were forced to abandon their old wayof life for a radically new survival strategy that resultedin widespread starvation and disease. The adaptation was farming： the global-warming crisis that gave rise to it happened more than 10,000 years ago.考试大As environmentalists convene in Rio de Janeiro this weekto ponder the global climate of the future, earth scientistsare in the midst of a revolution in understanding how climate has changed in the past—and how those changes have transformed human existence. Researchers have begun to piece together an illuminating picture of the powerful geological and astronomical forces that have combined to change the planet’s environment from hot to cold, wet to dry and back again over a time period stretching back hundreds of millions of year.Most important, scientists are beginning to realize that the climatic changes have had a major impact on the evolution of the human species. New research now suggests that climate shifts have played a key role in nearly every significant turning point in human evolution： from the dawn ofprimates(灵长目动物)some 65 million years ago to human ancestors rising up to walk on two legs, from the huge expansion of the human brain to the rise of agriculture. Indeed, the human history has not been merely touched by global climate change, some scientists argue, it has in some instances been driven by it.The new research has profound implications for the environmental summit in Rio. Among other things, the findings demonstrate that dramatic climate change is nothing new for planet Earth. The benign(宜人的)global environment that has existed over the past 10,000 years—during which agriculture, writing, cities and most other features of civilization appeared—is a mere bright spot in a much larger pattern of widely varying climate over the ages. In fact, the pattern or climate change in the past reveals that Earth’s climate will almost certainly go through dramatic changes in the future—even without the influence of human activity.21. Farming emerged as a survival strategy because man had been obliged .A) to give up his former way of lifeB) to leave the coastal areasC) to follow the ever-shifting vegetationD) to abandon his original settlement考试大24. Earth scientists have come to understand that climate .A) is going through a fundamental changeB)has been getting warmer for 10,000 yearsC) will eventually change from hot to coldD) has gone through periodical change23. Scientists believe that human evolution .A) has seldom been accompanied by climatic changesB) has exerted little influence on climatic changesC) has largely been effected by climatic changesD) has had a major impact on climatic changes24. Evidence of past climatic changes indicates that .A) human activities have accelerated changes of Earth’s environmentB) Earth’s environment will remain mild despite human interference。

2019年6月英语四级阅读真题及答案：长篇阅读段落匹配

2019年6月英语四级阅读真题及答案：长篇阅读段落匹配Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Resilience Is About How You Recharge, Not How You Endure[A] As constant travelers and parents of a 2-year-old, we sometimes fantasize about how much work we can do when one of us gets on a plane, undistracted by phones, friends, or movies. We race to get all our ground work done: packing, going through security, doing a last-minute work call, calling each other, then boarding the plane. Then, when we try to have that amazing work session in flight, we get nothing done. Even worse, after refreshing our email or reading the same studies over and over, we are too exhausted when we land to soldier on with (继续处理) the emails that have inevitably still piled up.[B] Why should flying deplete us? We’re just sitting there doing nothing. Why can’t we be tougher, more resilient (有复原力的) and determined in our work so we can accomplish all of the goals we set for ourselves? Based on our current research, we have come to realize that the problem is not our hectic schedule or the plane travel itself; the problem comes from a misconception of what it means to be resilient, and the resulting impact of overworking.[C] We often take a militaristic, “tough” approach to resilience and determination like a Marine pulling himself through the mud, a boxer going one more round, or a football player picking himself up off the ground for one more play. We believe that the longer we tough it out, the tougher we are, and therefore the more successful we will be. However, this entire conception is scientifically inaccurate.[D] The very lack of a recovery period is dramatically holding back our collective ability to be resilient and successful. Research has found that there is a direct correlation between lack of recovery and increased incidence of health and safety problems. And lack of recovery—whether by disrupting sleep with thoughts of work or having continuous cognitive arousal by watching our phones—is costing our companies $62 billion a year in lost productivity.[E] And just because work stops, it doesn’t mean we arerecovering. We “stop” work sometimes at 5pm, but then we spend the night wrestling with solutions to work problems, talking about our work over dinner, and falling asleep thinking about how much work we’ll do tomorrow. In a study just released, researchers from Norway found that 7.8% of Norwegians have become workaholics(工作狂). The scientists cite a definition of “workaholism”as “being overly concerned about work, driven by an uncontrollable work motivation, and investing so much time and effort in work that it impairs other important life areas.”[F] We believe that the number of people who fit that definition includes the majority of American workers, which prompted us to begin a study of workaholism in the U.S. Our study will use a large corporate dataset from a major medical company to examine how technology extends our working hours and thus interferes with necessary cognitive recovery, resulting in huge health care costs and turnover costs for employers.[G] The misconception of resilience is often bred from an early age. Parents trying to teach their children resilience might celebrate a high school student staying up until 3am to finish a science fair project. What a distortion of resilience! A resilient child is a well-rested one. When an exhausted student goes to school, he risks hurtingeveryone on the road with his impaired driving; he doesn’t have the cognitive resources to do well on his English test; he has lower self-control with his friends; and at home, he is moody with his parents. Overwork and exhaustion are the opposite of resilience and the bad habits we acquire when we’re young only magnify when we hit the workforce.[H] As Jim Loehr and Tony Schwartz have written, if you have too much time in the performance zone, you need more time in the recovery zone, otherwise you risk burnout. Gathering your resources to “try hard” requires burning energy in order to overcome your currently low arousal level. It also worsens exhaustion. Thus the more imbalanced we become due to overworking, the more value there is in activities that allow us to return to a state of balance. The value of a recovery period rises in proportion to the amount of work required of us.[I] So how do we recover and build resilience? Most people assume that if you stop doing a task like answering emails or writing a paper, your brain will naturally recover, so that when you start again later in the day or the next morning, you’ll have your energy back. But surely everyone reading this has had times when you lie in bed for hours, unable to fall asleep because your brain is thinking about work. If you lie in bed for eight hours, you may have rested,but you can still feel exhausted the next day. That’s because rest and recovery are not the same thing.[J] If you’re trying to build resilience at work, you need adequate internal and external recovery periods. As researchers Zijlstra, Cropley and Rydstedt write in their 2014 paper: “Internal recovery refers to the shorter periods of relaxation that take place within the frames of the work day or the work setting in the form of short scheduled or unscheduled breaks, by shifting attention or changing to other work tasks when the mental or physical resources required for the initial task are temporarily depleted or exhausted. External recovery refers to actions that take place outside of work—e.g. in the free time between the work days, and during weekends, holidays or vacations.” If after work you lie around on your bed and get irritated by political commentary on your phone or get stressed thinking about decisions about how to renovate your home, your brain has not received a break from high mental arousal states. Our brains need a rest as much as our bodies do.[K] If you really want to build resilience, you can start by strategically stopping. Give yourself the resources to be tough by creating internal and external recovery periods. Amy Blankson describes how to strategically stop during the day by using technology to control overworking. She suggestsdownloading the Instant or Moment apps to see how many times you turn on your phone each day. You can also use apps like Offtime or Unplugged to create tech free zones by strategically scheduling automatic airplane modes. The average person turns on their phone 150 times every day. If every distraction took only 1 minute, that would account for 2.5 hours a day.[L] In addition, you can take a cognitive break every 90 minutes to charge your batteries. Try to not have lunch at your desk, but instead spend time outside or with your friends—not talking about work. Take all of your paid time off, which not only gives you recovery periods, but raises your productivity and likelihood of promotion.[M] As for us, we’ve started using our plane time as a work-free zone, and thus time to dip into the recovery phase. The results have been fantastic. We are usually tired already by the time we get on a plane, and the crowded space and unstable internet connection make work more challenging. Now, instead of swimming upstream, we relax, sleep, watch movies, or listen to music. And when we get off the plane, instead of being depleted, we feel recovered and ready to return to the performance zone.36. It has been found that inadequate recovery often leads to poor health and accidents.37. Mental relaxation is much needed, just as physical relaxation is.38. Adequate rest not only helps one recover, but also increases one’s work efficiency.39. The author always has a hectic time before takinga flight.40. Recovery may not take place even if one seems to have stopped working.41. It is advised that technology be used to prevent people from overworking.42. Contrary to popular belief, rest does not equal recovery.43. The author has come to see that his problem results from a misunderstanding of the meaning of resilience.44. People’s distorted view about resilience may have developed from their upbringing.45. People tend to think the more determined they are, the greater their success will be.答案：36.D37. J38. L39. A40.

Overnight,Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colderthan Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zeroin Park Rapids, Minnesota, and 45 degreesbelow zero in Buffalo, North Dakota,according to the National Weather Service. Schools, restaurants, and businessesclosed, and more than l ,000 flights have been canceled.【[B] Even the United States Postal Service (USPS) suspended mail deliverytemporarily. "Due to this arctic outbreak and concerns for the safety of USPSemployees," USPS announced Wednesday morning, the Postal Service is suspendingdelivery Jan. 30 in the following 3-digit ZIP Code locations." Twelve regions werelisted as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extremeweather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and othernatural disasters cost at least $49 billion in the United States. As my colleague VannNewkirk reported, Puerto Rico is still confronting economic and structural destructionand resource scarcity from 2017's Hurricane Maria. Natural disasters can wreck acommunity's infrastructure, disrupting systems for months or years. Some services,however, remind us that life will eventually return, in some form, to normal,[D] Days after the deadly 2017 wildfires in Santa Rosa, California, a dronecaught footage of a USPS worker, Trevor Smith, driving through burned homes in thatfamiliar white van, collecting mail in an affected area. The video is striking: Theoperation is familiar, but the scene looks like the end of the world. According to RaeAnn Haight, the program manager for thenational-preparedness office at USPS,Smith was fulfilling a request made by some of the home owners to pick up any mailthat was left untouched. For Smith, this was just another day on the job. I followedmy route like I normally do," Smith told a reporter. As I'd come across a box thatwas up but with no house, I checked, and there was mail- -outgoing mail- -in it. Andso we picked those up and carried on.'[E] USPS has sophisticated emergency plans for natural disasters. Across thcountry, 285 emergency-management teams are devoted to crisis control. These teamsare trained annually using a framework known as the three Ps: people, property,product. After mail service stops due to weather, the agency 's top priority is ensuringthat employees are safe. Then it evaluates the health of infrastructure, such as theroads that mail carriers drive on. Finally, it decides when and how to re-openoperations. If the destruction is extreme, mail addressed to the area will get sentelsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming NewOrleans mail to existing mail facilities in Houston. Mail that was already processed inNew Orleans facilities was moved to an upper floor so it would be protected fromwater damage.[F] As soon as it's safe enough to be outside,' couriers start distributingaccumulated mail on the still-accessible routes. USPS urges those without standingaddresses to file change-of- address forms with their new location. After HurricaneKatrina hit in 2005, mail facilities were set up in dozens of other locations across thecountry in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, million pieces ofmail -anything from postcards to Social Security checks to medicine. Spokespeoplefrom both USPS and UPS told me all mail is important. But some mail can beextremely sensitive and timely. According to data released in January 2017, 56percent of bills are paid online, which means that just under half of payments still relyon delivery services to be completed.[H]It can be hard to identify which parcels are carrying crucial items such asSocial Security checks, but USPS and UPS try their best to prioritize sensitivematerial. They will coordinate with the Social Security Administration to make surethat Social Security checks reach the right people in a timely fashion. After HurricaneFlorence and Hurricane Michael last fall, USPS worked with state and local electionboards to make sure that absentee ballots were available and received on time.^[I] Mail companies are logistics companies, which puts them in a special positionto help when disaster strikes. In a 2011 USPS case study, the agency emphasized itsmassive infrastructure as a unique federal asset" to be called upon in a disaster orterrorist attack. I think we're unique as a federal agency," USPS official MikeSwigart told me, because we're in literally every community in this countryWe' re obligated to deliver to that point on a daily basis.'[J]Private courier companies, which have more dollars to spend, use theirexpertise in logistics to help revitalize damaged areas after a disaster. For more than adecade, FedEx has supported the American Red Cross in its effort to get emergencysupplies to areas affected by disasters, both domestically and internationally. In 2012,the company distributed more than 1,200 MedPacks to Medical Reserve Corps groupsin California, and donated space for million pounds of charitable shipping October, the company pledged $1 million in cash and transportation support forHurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, usesthe company 's logistics to help disaster-struck areas rebuild. We realize that as acompany with people, trucks, warehouses, we needed to play a larger role," saidEduardo Martinez, the president of the UPS Foundation. The company employs it:trucks and planes to deliver food, medicine, and water. The day before I spoke toMartinez in November, he had been touring the damage from Hurricane Michael inFlorida with the American Red Cross. Wehave an obligation to make sure ourcommunities are thriving, prosperous," he said.[K] Rebuilding can take a long time, and even then, impressions of the disastermay still remain. Returning to a sense of normalcy can be difficult, but some smallroutines- -mail delivery being one of them- -may help residents remember that theircommunities are still their communities. When they see that carrier back out on thestreet," Swigart said, that's the first sign to them that life is starting to return tonormal."36. The United States Postal Service has a system to ensure its employees' safety.37. One official says USPS is unique in that it has more direct reach tccommunities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half ofpayments.！40. The sight of a mailman on the street is a reassuring sign of life becomingnormal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail servicepoints were set up.42. Postal service in some regions in the . was suspended due to extreme coldweather.43. Private postal companies also support disaster relief efforts by distributingurgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite ofextreme conditions.45. Postal services work hard to identify items that require priority treatment.Section CDirections: There are 2 passages in this section. Each passage is followed by some;questions or unfinished statements. For each of them there are fourchoices marked A), B), C) and D). You should decide on the best choiceand mark the corresponding letter on Answer Sheet 2 with a single line 'through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligentteaching assistant to help handle the enormous number of student questions in theonline class, Knowledge Based Artificial Intelligence. This online course is a corerequirement of Georgia Tech's online Master of Science in Computer Scienceprogram. Professor Goelalready had 8 teaching assistants, but that wasn t enough todeal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching students feel isolated or confused and reach out with questions that gounanswered, their motivation to continue begins to fade. Professor Goel decided to dosomething to remedy this situation and his solution was to create a virtual assistantnamed Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill W atson before releasing herto the online forums. At first, the virtual assistant wasnt too great. But Goel and histeam sourced the online discussion forum to find all 40,000 questions that had everbeen asked since the class was launched. Then they began to feed Jill the questionsand answers. After some adjustment and sufficient time, Jill was able to answer thestudents questions correctly 97% of the time. The L virtual assistant became soadvanced and realistic that the students didn t know she was a computer. The students,who were studying artificial intelligence, were interacting with artificial intelligenceand couldn't tell it apart from a real human being. Goel didn 't inform them about Jill'strue identity until April 26. The students were actually very positive about theexperience.The goal of Professor Goel's virtual assistant next year is to take over answering40% of all questions posed by students on the online forum. The name, Jill Watson,will of course, change to something else next semester. Professor Goel has a muchrosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gatesor Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence】A) It is a robot that can answer students' questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet withA) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students questions were too many to handle.】D) Too many students dropped out of his course.48. What do we learn about Jill WatsonA) She turned out to be a great success.B) She got along pretty well with students.C) She was unwelcome to students at first.D) She was released online as an experiment.10/23149. How did the students feel about Jill W atson）A) They thought she was a bit too artificial.B) They found her not as capable as expected.C) They could not but admire her knowledge.D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill W atsonA) Launch different versions of her online.B) Feed her with new questions and answers.c) Assign her to answer more of students questions.&D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don' t hurt. Thoseare a few of the traits of successful science crowdfunding efforts that emerge from arecent study that examined nearly 400 campaigns. But having a large network andsome promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken offin recent years for everything from making movies to building water-saving have tried to tap Internet donors, too, with mixed success. Some raisedmore than twice their goal, but others have fallen short of reaching more modesttargets.To determine what separates science crowdfunding triumphs from failures, ateam led by science communications scholar Mike Schäfer of the University of Zurichin Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report inPublic Understanding of Science. For one, they use a crowdfunding platform thatspecializes in raising money for science, and not just any kind of project. Althoughsites like Kickstarter take all comers, platforms such as Experiment. com,, and Petridish. org only present scientific projects. For another, theypresent the project with a funny video because good visuals and a sense of humorimproved success. Most of them engage with potential donors since projects thatanswered questions from interested donors and posted lab notes fared better. And theytarget a small amount of money. The projects included in the study raised $4000 onaverage, with 30% of projects receiving less than $ 1000. The more money a projectsought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project's success, most notably,the size of a scientist's personal and professional networks, and how muchresearcher promotes a project on his or her own. Those two factors are by far morecritical than the content on the page. Crowdfunding can be part of researchers effortsto reach the public, and people givebecause they feel a connection to the person"who is doing the fundraising- -not necessarily to the science."11/3151. What do we learn about the scientists trying to raise money online for theirprojectsA) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schafer's research of recent crowdfundingcampaignsA) To create attractive content for science websites.^B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaignA) The potential benefit to future generations.为B) Its interaction with prospective donors.C) Its originality in addressing financial issues.$D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfundingprojectsA) They should be small to be successful.B) They should be based on actual needs.C) They should be assessed with great care.D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaignA) The ease of access to the content of the webpage.：B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part IV Translation (30 minutes) Directions: For this part, you cre allowed 30 minutes to translate a passage from( 'hinese into English.

N) challenges48. A) stable49. E) progress50. O) certainly51. D) role52. M) combined53. C) significant54. G) included55. K) comprise56. B) solutionsSection BPassage OneBoys' schools are the perfect place to teach young men to express their emotions and are more likely to get involvedin activities such as art, dance and music, according to research released today.Far from the traditional image of a culture of aggressive masculinity in which students either sink or swim, the absence of girls gives boys the chance to develop without pressure to conform to a stereotype, the US study says.Boys at single sex schools were said to be more likely to get involved in cultural and artistic activities thathelped develop their emotional expressiveness, rather than feeling they had to conform to the "boy code" of hiding their emotions to be a "real man".The findings of the study go against received wisdom that boys do better when taught alongside girls.Tony Little, headmaster of Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills.But in single-sex schools teachers can tailor lessons to boys' learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia.Teachers could encourage boys to enjoy reading andwriting with specifically "boy-focused" approaches such asthemes and characters that appeal to them. Because boysgenerally have more acute vision, learn best through touch,and are physically more active, they need to be given "hands-on" lessons where they are allowed to walk around. "Boys inmixed schools view classical music as feminine and prefer the modern genre in which violence and sexism are major themes," James wrote.Single-sex education also made it less likely that boyswould feel they had to conform to a stereotype that menshould be "masterful and in charge" in relationships. "Inmixed schools, boys feel compelled to act like men beforethey understand themselves well enough to know what that means," the study reported.57. The author believes that a single-sex school would_____________________.A force boys to hide their emotions to be “real man ”B help to cultivate masculine aggressiveness in boysC encourage boys to express their emotions more freelyD naturally reinforce in boys that traditional image ofa man58. It is commonly believed that in a mixed schools boys____________________.A perform relatively betterB grow up more healthilyC behave more responsiblyD receive a better education59. What does Tony Little say about the Britisheducation system?A It fails more boys than girls academicallyB Itfocuses more on mixed school educationC It fails to give boys the attention they needD It places more pressure on boys than on girls60. According to Abigail James, one of the advantages of single-sex schools is ______________.A teaching can be tailored to suit the characteristicsof boysB boys can focus on their lessons without being distractedC boys can choose to learn whatever they are interestedinD teaching can be designed to promote boys ’team spirit61. Which of the following is characteristic of boys according to Abigail James ’report?A They enjoy being in chargeB They conform to stereotypesC They have sharper visionD They are violent and sexistPassage TwoIt's an annual argument. Do we or do we not go on holiday? My partner says no because the boiler could go, orthe roof fall off, and we have no savings to save us. I saythat you only live once and we work hard and what's the pointif you can't go on holiday. The joy of a recession means no argument next year –we just won't go.Since money is known to be one of the things most likelyto bring a relationship to its knees, we should be grateful.For many families the recession means more than not booking a holiday. A YouGov poll of 2,000 people found 22% said theywere arguing more with their partners because of concernsabout money. What's less clear is whether divorce and separation rates rise in a recession –financial pressures mean couples argue more but make splitting up less affordable.A recent research shows arguments about money were especially damaging to couples. Disputes were characterized by intense verbal aggression, tended to be repeated and not resolved,and made men, more than women, extremely angry.Kim Stephenson, an occupational psychologist, believes money is such a big deal because of what it symbolizes, whichmay be different things to men and women. "People can say the same things about money but have different conceptions ofwhat it is for," he explains. "They will say it's to save, tospend, for security, for freedom, to show someone you love them" He says men are more likely to see money as a way of buying status and of showing their parents that they'veachieved something."The biggest problem is that couples assume each other knows what is going on with their finances, but they don't.There seems to be more of a taboo about talking about moneythan talking about death. But you both need to know what youare doing, who is paying what into the joint account and howmuch you keep separately. In a healthy relationship you don'thave to agree about money, but you have to talk about it."62. What does the author say about vacationing?A People enjoy it all the more during a recessionB Few people can afford it without working hardC It makes all the hard work worthwhileD It is the chief cause of family disputes63. What does the author mean by saying “money is known⋯to bring a relationship to its knees ”(Line 1 Para.2)?A Money is considered to be the root of all evilsB Some people sacrifice their dignity for moneyC Few people can resist the temptation of moneyD Disputes over money may ruin a relationship64. The YouGov poll of 2000 people indicates that in a recession _________________.A conflicts between couples tend to riseB it is more expensive for couples to split upC couples show more concern for each otherD divorce and separation rates increase65. What does Kim Stephenson believe?A Money is often a symbol of a person ’s statusB Money means a great deal to both men and womenC Men and women spend money on different thingsD Men and women view money in different ways66. The author suggests at the end of the passage thatcouples should ________________A put their money together instead of keeping itseparatelyB make efforts to reach agreement on their familybudgetsC discuss money matters to maintain a healthyrelationshipD avoid arguing about money matters to remain romantic参考答案57. C) encourage boys to express their emotions morefreely58. A) perform relatively better59. C) It fails to give boys the attention they need 。

today.With the improvement of housing conditions,a growing number of young cou-ples choose to live separately from their parents but their connection remains close.Many seniors still help look after

2019年12月大学英语四级考试阅读讲义(四十五)

2019年12月大学英语四级考试阅读讲义(四十五) Unit 18Part II Reading Comprehension(35 minutes)Passage OneQuestions 11 to 15 are based on the following passage.Birds that are literally half-asleep─with one brain hemisphere alert and the other sleeping─control which side of the brain remains awake, according to a new study of sleeping ducks.考试大Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.Decades of studies of bird flocks led researchers to predict extra alertness in the more vulnerable, end-of-the-row sleepers. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.Also, birds dozing(打盹) at the end of the line resorted to single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Rotating 16 birds through the positions in a four-duck row, the researchers found outerbirds half-asleep during some 32 percent of dozing time versus about 12 percent for birds in internal spots.“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness simultaneously in different regions of the brain,” the researchers say.The results provide the best evidence for a long-standing supposition that single-hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout s ide could be widespread, he predicts. He’s seen it in a pair of birds dozing side-by-side in the zoo and in a single pet bird sleeping by a mirror.

Passage OneQuestions 21 to 25 are based on the following passage.オ
Bill Gates, the billionaire Microsoft chairman without a single earned university degree, is by his success raising
new doubts about the worth of the business world's favorite academic title： the MBA (Master of Business Administration). The MBA, a 20th-century product, always has borne the mark of lowly commerce and greed (贪婪) on the tree-lined campuses ruled by purer disciplines such as philosophy and literature. But even with the recession apparently cutting into the
hiring of business school graduates, about 79,000 people are expected to receive MBAs in 1993.This is nearly 16 times the number of business graduates in 1960,a testimony to the widespread assumption that the MBA is vital for young men and women who want to run companies some day.“If you are going into the corporate world it is still a disadvantage not to have one," said Donald Morrison, professor of marketing and
management science.“But in the last five years or so, when someone says, ‘Should I attempt to get an MBA,' the answer a lot more is： It depends." The success of Bill Gates and
other non-MBAs, such as the late Sam Walton of Wal-Mart
Stores Inc. has helped inspire self-conscious debates on business school campuses over the worth of a business degree and whether management skills can be taught.
The Harvard Business Review printed a lively, fictional exchange of letters to dramatize complaints about business degree holders. The article called MBA hires “extremely disappointing" and said “MBAs wants to move up too fast,
they don't understand politics and people, and they aren't
able to function as part of a team until their third year.
But by then, they're out looking for other jobs." The problem, most participants in the debate acknowledge, is that the MBA has acquired an aura (光环) of future riches and power far beyond its actual importance and usefulness. Enrollment in business schools exploded in the 1970s and 1980s and created the assumption that no one who pursued a business career
could do with out one. The growth was fueled by a backlash(反冲)against the anti-business values of the 1960s and by the women's movement. Business people who have hired or worked
with MBAs say those with the degrees of ten know how to analyze systems but are not so skillful at motivating
people.“They don't get a lot of grounding in the people side of the business, "said James Shaffer, vice-president and principal of the Towers Perrin management consulting firm.
