Text 1A new study suggests that contrary to most surveys. People art actually more stressed at home than at work. Researchers measured people's cortisol , which is it at stress marker,while they were at work and while they were at home and found it higher at what is supposed to be a place of refuge.“Further contradicting conventional wisdom,we found that women as well as men have lower levels of stress at work than at home,” writes one of the researchers. Sarah Damaske,In fact women say they feel better a t wor k. She notes. “it is men not women. Who report being happier at home than at work,” Another surprise is that the findings hold true for both those with children without,but more so for nonparents. This is why people who work outside the home have better health.What the study doesn't measure is whether people are still doing work when they' re at home,whether it is household work or work brought home from the office. For many men,the end of the workday is a time to kick back. For women who stay home, they never get to leave the office. And for women who work outside the home, they often are playing catch-up-with-household tasks. With the blurring of roles, and the fact that the home front lags well behind the workplace in making adjustments for working women,it' s not surprising that women are more stressed at home.But it's not just a gender thing. At work, people pretty muchknow what they're supposed to be doing:working,making money,doing the tasks they have to do in order to draw an income. The bargain is very pure:Employee puts in hours of physical or mental labor and employee draws out life-sustaining moola.On the home front, however, people have no such clarity. Rare is the household in which the division of labor is so clinically and methodically laid out. There are a lot of tasks to be done,there are inadequate rewards for most of them. Your home colleagues-your family-have no clear rewards for their labor; they need to be talked into it, or if they' re teenagers,threatened with complete removal of all electronic devices. Plus, they' re your family. You cannot fire your family. You never really get to go home from home.So it's not surprising that people are more stressed at home. Not only are the tasks apparently infinite, the co-workers are much harder to motivate.21.According to Paragraph 1,most previous surveys found that home ______.[A]was an unrealistic place for relaxation[B]generated more stress than the workplace[C]was an ideal place for stress measurement[D]offered greater relaxation than the workplace22.According to Damaske, who are likely to be the happiest at home?[A]Working mothers[B]Childless husbands[C] Childless wives[D]Working fathers23 The blurring of working women's roles refers to the factthat ______.[A]they are both bread winners and housewives[B]their home is also a place for kicking back[C]there is often much housework left behind[D]it is difficult for them to leave their office24.The word“moola”(Line 4,Para 4)most probably means ______.[A]energy[B]skills[C]earnings[D]nutrition25.The home front differs from the workplace in that ______.[A]home is hardly a cozier working environment[B]division of labor at home is seldom clear-cut[C]household tasks are generally more motivating[D]family labor is often adequately rewarded【参考答案】21. D 22. B 23. A 24. C 25. B【主要内容】本文主要讲述工作环境压力问题。

2017年考研英语(一)阅读真题及答案解析

2017年考研英语(一)阅读真题及答案解析2017年考研英语考试已经结束!店铺考研网在考后第一时间为大家提供2017年考研英语(一)阅读真题及答案解析,更多考研资讯请关注我们网站的更新!2017年考研英语(一)阅读真题及答案解析英语(一)阅读最后一篇文章有一点升华了,有一点小高潮,谈最高法院,在视频当中反复强调过,一定关注今年考试,一定会关注的重点话题,第三篇文章谈经济,第四篇谈法律题材。

不能仅仅背几个单词,一定要关注这些词、这些概念背后背景,以及词和词之间、概念和概念连接。

美国最高法院,想到谁了,历史惊人相似,2013年第四篇文章,我们最高法庭驳回了奥巴马政府,用一模一样的内容。

他说最高法庭推翻了对于这个人的受贿指控。

但是后面考了一个句子题,下划线句子怎么样,类似2004年这个人再也没有咬他的指甲,当时经济低迷咬指甲显示出他精神紧张。

后面出现了一个but,前面大方向是积极向上的。

这道题同样如此。

我们第一句话说我们驳回了,推翻了有罪,受贿判决。

后面说但是,大方向是向下的。

这道题选择的是对于这个人行为本身,感到了非常的可耻。

令人感到鄙视。

其他选项再比较选项的时候,干扰选项你明白考研命题思路,可以帮你更快更准更高效抓住正确答案。

第二题是细节题,到第四段怎么样,问你的是一个条件,只要什么样情况下我们才认为受贿罪是成立的呢。

其中A选项,给你送礼物的人那里得到非常具体的实在的回报。

这是我们的答案。

对原文做了同义改写。

第三题是目前我们整个法庭宣判,是基于什么样的假设。

我们公共部门的官员们,应该干吗?也是一道细节题。

这是我们说了解美国选举体制,我之所以给你投票唯一原因是干吗?上任以后带来我的好处。

这是非常合理的。

你和我们中国的一些传统文化当中一定有相冲突的地方,我们觉得做公务员干吗叫大公无私。

美国环境里不是这样的。

选民之所以选你因为你能够给我们带来好处。

他认为处理、满足我们的背后这些支持人的需求是理所当然的,是正当的。

2017年考研英语一阅读真题及答案解析

2017年考研英语一阅读真题及答案解析2017年考研英语考试已经结束!店铺考研网在考后第一时间为大家提供2017年考研英语一阅读真题及答案解析,更多考研资讯请关注我们网站的更新!2017年考研英语一阅读真题及答案解析大家也做了题,也发现今年题目并没有传说中那么难,四篇阅读理解前面三篇中等,不是很难。

第四篇和法律有关的文章大家觉得有点难度。

我今年也去考试了,这就是我的证据。

但是我的反面抄了一些答案,当然有些监考不让抄答案,我很潦草地抄了一些,想看它的难度和我们平常所学的能否挂钩。

前三篇不难,第四篇难度和法律相关,有点像2013年的地四篇文章。

其实这篇文章我刚才查了一下原版出处是CNN里的,推翻了弗吉尼亚前州长贪污罪,他是无辜的。

都是英国美国文章居多。

美国有三篇文章。

第一篇是美国机场安检特别浪费时间。

今年特点是有七八个自然段,不是往年一样四五个自然段。

第一道题,这是一个力争题,往年考题也这么说,通过所谓关键词定位方法无效,一定要把握主要内容是讲什么。

这是讲我们目前为什么有必要进行严格的安全检查。

因为埃及航空公司受到了恐怖袭击,在地中海上空受到恐怖主义袭击。

所以现在要严格安检。

这道词选解释作用。

第二题是上面哪个能够解释为什么美国机场排队队伍很长很长。

这道题文章里给了好几个解释。

第一个原因是因为我们现在经济比较好,机票比较便宜,所以很多人愿意排队。

大家都愿意坐飞机,不愿意开车、不愿意坐火车。

导致排队队伍很长。

第二个原因是有些人要打包,第三段里说的,包裹需要检查,有些人打了好多包,为了逃避托运费。

导致排队比较长。

还有一个这里所说的安检效率降低。

但是我们按照前面的最重要的原因,还是因为美国政府没有注意到现在出行坐飞机的人增多了,导致速度减慢。

这是我们飞机出行人员增加。

23题是猜词题,我们不管上基础课、强化课还是单向课,有我的模糊阅读班,猜词题不能相信所谓构词法,按照EX这个单词是出去的意思。

这里EX给人错觉是出去的意思,但是根据上下文是希望安检越快越好。

考研英语_时⽂阅读50篇考拉进阶英语时⽂阅读50篇Passage1Dealing With Spam1:Confidence Game(2010.11.18The Economist)[483words]Bill Gates,then still Microsoft’s boss,was nearly rightin2004when he predicted the end of spam in two years.Thanks to clever filters2unsolicited3e-mail has largelydisappeared as a daily nuisance4for most on the internet.But spam is still a menace5:blocked at the e-mail inbox,spammers post messages as comments on websites and increasingly on social networks like Twitter and Facebook.The criminal businesses behind spam are competitive and creative.They vault over6technical fixes as fast as the hurdles7are erected.The anti-spam industry has done applaudable work in saving e-mail.But it is always one step behind.In the end,the software industry’s interest is in making money from the problem(by selling subscriptions to regular security updates)rather than tackling it at its source.Law-enforcement agencies have had some success shutting down spam-control servers in America and the Netherlands.But as one place becomes unfriendly, spammers move somewhere else.Internet connections in poor and ill-run countries are improving faster than the authorities there can police them.That won’t end soon.In any case,the real problem is not the message,but the link.Sometimes an unwise click leads only to a website that sells counterfeit8pills.But it can also lead to a page that infects your computer with a virus or another piece of malicious software that then steals your passwords or uses your machine for other immoral purposes. Spam was never about e-mail;it was about convincing us to click.To the spammer,it needs to be decided whether the link is e-mailed or liked.The police are doing what they can,and software companies keep on tightening security.But spam is not just a hack9or a crime,it is a social problem,too.If you look beyond the computers that lie between a spammer and his mark,you can see allthe classic techniques of a con-man:buy this stock,before everyone else does.Buy these pills,this watch,cheaper than anyone else can.The spammer plays upon the universal human desire to believe that we are smarter than anyone gives us credit for,and that things can be had for nothing.As in other walks of life,people become wiser and take precautions only when they have learned what happens when they don’t.That is why the spammers’new arena10—social networks—is so effective.A few fiddles might help,such as tougher default privacy settings on social networks.But the real problem is man,not the machine.Public behaviour still treats the internet like a village,in which new faces are welcome and anti-social behaviour a rarity.A better analogy would be a railway station in a big city,where hustlers11gather to prey on the credulity12of new arrivals.Wise behaviour in such places is to walk fast,avoid eye contact and be cautious with strangers.Try that

Gene to Explain Depression(2011.1.3Time)[459words]As powerful as genes are in exposing clues to diseases,not even the most passionate geneticist1believes thatcomplex conditions such as depression can be reduced to atell-tale2string of DNA.But a new study confirms earlier evidence that aparticular gene,involved in ferrying3a brain chemical critical to mood known as serotonin4,may play a role in triggering5the mental disorder in some people.Researchers led by Dr.Srijan Sen,a professor of psychiatry at University of Michigan,report in the Archives6of General Psychiatry that individuals with a particular form of the serotonin transporter gene were more vulnerable to developing depression when faced with stressful life events such as having a serious medical illness or being a victim of childhood abuse.The form of the gene that these individuals inherit prevents the mood-regulating serotonin from being re-absorbed by nerve cells in the brain.Having such a low-functioning version of the transporter starting early in life appears to set these individuals up for developing depression later on,although the exact relationship between this gene,stress,and depression isn’t clear yet.Sen’s results confirm those of a ground-breaking7study in2003,in which scientists for the first time confirmed the link between genes and environment in depression.In that study,which involved more than800subjects,individuals with the gene coding for the less functional serotonin transporter were more likely to develop depression following a stressful life event than those with the more functional form of the gene.But these findings were questioned by a2009analysis in which scientistspooled814studies investigating the relationship between the serotonin transporter gene,depression and stress,and found no heightened risk of depression among those with different versions of the gene.“One of the hopes I have is that we can settle this story,and move on to looking more broadly across the genome9for more factors related to depression,”he says.“Ideally we would like to find a panel of different genetic variations that go together to help us predict who is going to respond poorly to stress,and who might respond well to specific types of treatment as opposed to others.”He believes that the2009findings do not contradict those from2003,or the latest results,but rather reflect a difference in the way the study was conducted.Sen stresses,however,that this gene is only one player in the cast of genetic and environmental factors that contribute to depression.“All things considered,this gene is a relatively small factor,and for this finding to be clinically10useful,we really need to find many,many more factors.Ultimately we may identify new pathways that are involved in depression to come up with new and better treatments.”1.geneticist/dnet?s?st/n.遗传学家2.tell-tale/?tel?te?l/adj.暴露实情的,能说明问题的3.ferry/?fer?/vt.渡运,摆渡4.serotonin/?s??rt??n?n/n.[⽣化]⾎清素,5-羟⾊胺(神经递质,易影响情绪等)5.trigger/?tr?ɡ?/vt.触发,引发;开动,启动6.archive/?ɑ?ka?v/n.档案馆;档案⽂件7.ground-breaking/?gra?nd?bre?k??/adj.开创性的;创新的8.pool/pu?l/vt.合伙经营;集中(智慧等);共享,分享9.genome/??i?n??m/n.[⽣]基因组;[⽣]染⾊体组10.clinically/?kl?n?kl?/adv.临床地;冷淡地;通过临床诊断Passage3Second Thoughts on Online Education(2010.9New York Times)[415words]Let the computer do the teaching.Some studies,expertopinion and cost pressures all point toward a continuing shiftof education online.A major study last year,funded by the EducationDepartment,which covered comparative research over12years,concluded that online learning on average beat face-to-face teaching by a modest1but statistically meaningful margin2.Bill Gates,whose foundation funds a lot of education programs,predicted last month that in five years much of college education will have gone online.“The self-motivated learner will be on the Web,”Mr.Gates said,speaking at the Techonomy conference in Lake Tahoe.“College needs to be less place-based.”But recent research,published as a National Bureau of Economic Research working paper,comes to a different conclusion.“A rush to online education may come at more of a cost than educators may suspect,”the authors write.The research was a head-to-head experiment,comparing the grades achieved in the same introductory economics class by students—one group online,and one in classroom lectures.Certain groups did notably worse online.Hispanic3students online fell nearly a full grade lower than Hispanic students that took the course in class.Male students did about a half-grade worse online,as did low-achievers,which had college grade-point averages below the mean for the university.The difference certainly was not attributable4to machines replacing a tutorial-style human teaching environment.Instead,the classroom was a large lecture hall seating hundreds of students.Initially,David Figlio,an economist at Northwestern University and co-author of the paper,said he had thought that the flexibility5of the Internet—the ability to“go back and roll the tape”—would probably give the online coursework6an edge over traditional“chalk and talk teaching.”The online lectures were well done,using a professional producer and cameraman7.“It had very much the feel of being in the room,”Mr.Figlio said.So what accounts for the difference in outcomes8?Mr.Figlio has a few theories. For the poorer performance of males and lower-achievers,he says the time-shifting convenience of the Web made it easier for students to put off viewing the lectures and cram9just before the test,a tactic10unlikely to produce the best possible results.It’s partly a stereotype11but also partly true,Mr.Figlio says,that female students tend to be better at timemanagement,spreading their study time over a semester,than males.“And the Internet makes it easier to put off12the unpleasant thing,attending the lecture,”he said.1.modest/?m?d?st/adj.谦虚的,谦恭的;适中的,适度的;些许的2.margin/?mɑ:d??n/n.页边空⽩;边,边缘;差数,差额3.Hispanic/h?s?p?n?k/adj.西班⽛和葡萄⽛的4.attributable/??tr?bj?t?bl/adj.可归因于,可能由于5.flexibility/?fleks??b?l?t?/n.灵活性;柔韧性6.coursework/?k?:sw?:k/n.课程作业7.cameraman/?k?m?r?m?n/n.摄影师8.outcome/?a?tk?m/n.结果9.cram/kr?m/v.挤满,塞满;临时死记硬背10.tactic/?t?kt?k/n.兵法;⽅法,策略;⼿段;招数11.stereotype/?ster??ta?p/n.模式化观念,⽼⼀套,刻板形象12.put off撤销,取消Passage4The Kids Can’t Help It(2010.12.16Newsweek)[372words]What new research reveals about the adolescentbrain—from why kids bully1to how the teen yearsshape the rest of your life.They say you never escape high school.And forbetter or worse,science is lending some credibility tothat old saw.Thanks to sophisticated imaging technology and a raft2of longitudinal3studies,we’re learning that the teen years are a period of crucial brain development subject to a host of environmental and genetic factors.This emerging research sheds4light not only on why teenagers act they way they do,but how the experiences of adolescence—from rejection to binge5 drinking—can affect who we become as adults,how we handle stress,and the way we bond with others.One of the most important discoveries in this area of study,says Dr.Frances Jensen,a neuroscientist at Harvard,is that our brains are not finished maturing by adolescence,as was previously thought.Adolescent brains“are only about80percentof the way to maturity,”she said at the annual meeting of the Society for Neuroscience in November.It takes until the mid-20s,and possibly later,for a brain to become fully developed.An excess of gray matter6(the stuff that does the processing)at the beginning of adolescence makes us particularly brilliant at learning—the reason we’re so good at picking up new languages starting in early childhood—but also particularly sensitive to the influences of our environment,both emotional and physical.Our brains’processing centers haven’t been fully linked yet,particularly the parts responsible for helping to check7our impulses8and considering the long-term repercussions9of our actions.“It’s like a brain that’s all revved10up not knowing where it needs to go,”says Jensen.It’s partially because of this developmental timeline that a teen can be so quick to conjure11a stinging remark,or a biting insult,and so uninhibited12in firing it off at the nearest unfortunate target—a former friend,perhaps,or a bewildered parent.The impulse to hurl13an insult14is there,just as it may be for an adult in a stressful situation,but the brain regions that an adult might rely on to stop himself from saying something cruel just haven’t caught up.1.bully/?b?l?/v.恐吓;充当恶霸,恃强凌弱2.raft/rɑ?ft/n.筏;橡⽪艇,充⽓船;⼤量3.longitudinal/?l?ntju?d?nl/adj.纵向的;纵观的;经度的4.shed/?ed/vt.散发出光;去除,摆脱;蜕,落5.binge/b?nd?/n.饮酒作乐;狂饮;狂闹6.gray matter灰质(脑、脊髓内神经元集中的地⽅)7.check/t?ek/v.检查,核验,核对;制⽌,控制8.impulse/??mp?ls/n.冲动;脉冲;刺激,推动⼒9.repercussion/?ri?p??kn/n.(间接的)反响,影响,恶果10.rev/rev/v.(发动机等)加快转速11.conjure/?k?n??/v.变魔术;使变戏法般地出现(或消失)12.uninhibited/??n?n?h?b?t?d/adj.⽆限制的;⽆拘束的,放任的13.hurl/h??l/vt.猛掷,猛扔;⼤声说出14.insult/?n?s?lt/n.侮辱;凌辱;⽆礼Passage5The Power of Posture(2011.1.13The Economist)[486words]“Stand up straight!”“Chest out!”“Shoulders back!”Theseare the perennial1cries of sergeant2majors and fussy3parentsthroughout the ages.Posture certainly matters.Big is dominantand in species after species,humans included,postures thatenhance the posturer’s apparent size cause others to treat him asif he were more powerful.The stand-up-straight brigade4,however,often make a further claim:that posture affects the way the posturer treats himself,as well as how others treat him.To test the truth of this,Li Huang and Adam Galinsky,at Northwestern University in Illinois,have compared posture’s effects onself-esteem with those of a more conventional ego-booster,management responsibility. In a paper just published in Psychological Science they conclude,surprisingly,that posture may matter more.The two researchers’experimental animals—77undergraduate students—first filled out questionnaires5,ostensibly6to assess their leadership capacity.Half were then given feedback forms which indicated that,on the basis of the questionnaires, theywere to be assigned to be managers in a forthcoming7experiment.The other half were told they would besubordinates8.While the participants waited for this feedback, they were asked to help with a marketing test on ergonomic9chairs.In fact,neither of these tests was what it seemed.The questionnaires were irrelevant.V olunteers were assigned to be managers or subordinates at random.The test of posture had nothing to do with ergonomics.And,crucially,each version of the posture test included equal numbers of those who would become“managers”and “subordinates”.Once the posture test was over the participants received their new statuses and the researchers measured theirimplicit10sense of power by asking them to engage in a word-completion task.Participants were instructed to complete a number of fragments11with the first word that came to mind.Seven of the fragments could be interpreted as words related to power(“power”,“direct”,“lead”,“authority”,“control”,“command”and“rich”).Although previous studies suggested a mere title is enough to produce a detectable increase in an individual’s sense of power,Dr Huang and Dr Galinsky found no difference in the word-completion scores of those told they would be managers and those told they would be subordinates.Having established the principle,Dr Huang and Dr Galinsky went on to test the effect of posture on other power-related decisions:whether to speak first in a debate, whether to leave the site of a plane crash to find help and whether to join a movement to free a prisoner who was wrongfully locked up.In all three cases those who had sat in expansive12postures chose the active option(to speak first,to search for help,to fight for justice)more often than those who had sat crouched13. The upshot14,then,is that father(or the sergeant major)was right.Those who walk around with their heads held high not only get the respect of others,they seem also to respect themselves.1.perennial/p??ren??l/adj.[植]多年⽣的;长久的,持续的2.sergeant/?sɑnt/n.[军](英)陆军、空军、海军陆战队中⼠;(美)陆军或空军中⼠3.fussy/?f?s?/adj.挑剔的,⼤惊⼩怪的;紧张不安的4.brigade/?br?ɡe?d/n.旅;伙,帮,派5.questionnaire/?kwestn e?/n.问卷;调查表6.ostensibly/?s?tens?bl?/adv.表⾯上;明显地7.forthcoming/?f??θ?k?m??/adj.即将发⽣的;现成的;乐于提供信息的8.subordinate/s??b??d?n?t/n.下级,部属9.ergonomic/ɡn?m?k/adj.⼈类⼯程学的10.implicit/?m?pl?s?t/adj.不⾔明的,含蓄的11.fragment/?fr?ɡm?nt/n.碎⽚,⽚段12.expansive/?ks?p?ns?v/adj.⼴阔的,辽阔的;⼴泛的,全⾯的;友善健谈的,开朗的13.crouch/kraut?/vt.屈膝,蹲伏,蹲,蹲下14.upshot/??p??t/n.最后结果,结局Passage6How Rest Helps Memory:Sleepy Heads(2010.2.25The Economist)[402words]Mad dogs and Englishmen,so the song has it,go out in themidday sun.And the business practices of England’s linealdescendant1,America,will have you in the office from nine in themorning to five in the evening,if not longer.Much of the world,though,prefers to take a siesta2.And research presented to theAAAS meeting in San Diego suggests it may be right to do so.Ithas already been established that those who siesta are less likely todie of heart disease.Now,Matthew Walker and his colleagues at the University of California,Berkeley,have found that they probably have better memory, too.A post-prandial3snooze4,Dr Walker has discovered,sets the brain up for learning.The role of sleep in consolidating5memories that have already been created has been understood for some time.Dr Walker has been trying to extend this understanding by looking at sleep’s role in preparing the brain for the formation of memories in the first place.He was particularly interested in a type of memory called episodic6memory,which relates to specific events,places and times.This contrasts with procedural memory,of the skills required to perform some sort of mechanical task,such as driving.The theory he and his team wanted to test was that the ability to form new episodic memories deteriorates7with increased wakefulness,and that sleep thus restores the brain’s capacity for efficient learning.They asked a group of39people to take part in two learning sessions,one at noon and one at6pm.On each occasion the participants tried to memorise and recall 100combinations of pictures and names.After the first session they were assigned randomly to either a control group,which remained awake,or a nap group,which had 100minutes of monitored sleep. Those who remained awake throughout the day became worse at learning.Those who napped8,by contrast,actually improved their capacity to learn,doing better in the evening than they had at noon.These findings suggest that sleep is clearing the brain’s short-term memory and making way for new information.The benefits to memory of a nap,says Dr Walker,are so great that they can equal an entire night’s sleep.Hewarns,however,that napping must not be done too late in the day or it will interfere with night-time sleep.Moreover,not everyone awakens refreshed from a siesta.1.lineal descendant直系后裔2.siesta/s??est?/n.午睡,午休3.prandial/?pr?nd??l/adj.膳⾷的,正餐的4.snooze/snu:z/n.⼩睡5.consolidate/k?n?s?l?de?t/vt.使巩固,使加强;合并6.episodic/?ep??s?d?k/adj.偶尔发⽣的,不定期的;有许多⽚段的7.deteriorate/d??t??r??re?t/vi.恶化,退化;变坏8.nap/n?p/vi.⼩睡Passage7Learning Gap Between Rich and Poor Starts Early(2011.2Newsweek)[354words]It’s generally accepted that there is a correlationbetween a child’s educational attainment1and a family’spoverty level,but new research shows that the problemmay take root2earlier than previously thought.A new study in Psychological Science found that at10months old,children from poor families performed just as well as children from wealthier families,but by the time they turned2,children from wealthier families were scoring consistently higher than those from poorer ones.“Poor kids aren’t even doing as well in terms of school readiness,sounding out letters and doing other things that you would expect to be relevant to early learning,”Elliot M.Tucker-Drob of the University of Texas at Austin,lead author of the study, said in a press release.To conduct the study,researchers assessed the mental abilities of about750pairs of fraternal3and identical4twins from all over the U.S.The participants’socioeconomic status was determined based on parents’educational attainment, occupations and family income.Each child was asked to perform tasks that included pulling a string to ring a bell, placing three cubes in a cup,matching pictures and sorting pegs by color first at10 months and again when they were2years old.At this time,researchers discovered that during the14-month window between the aptitude5tests,gaps in cognitive6 development had started to occur.Children from wealthier families had started to consistently outperform those from poorer ones.Researchers attempted to disprove7a genetic explanation by comparing the aptitude tests of each set of twins.Among the2-year-olds from wealthier families, identical twins had much more similar test scores than fraternal twins,who share only half of their genes.However,among2-year-olds from poorer families,identical twins scored no more similar to one another than did fraternal twins.The implication is that children’s genetic potential is subdued8by poverty, though the study stopped short of drawing a scientific conclusion as to what specifically was causing the achievement gaps.Researchers did postulate9that, generally speaking,poorer parents may not have the time or resources to spend playing with their children in stimulating ways.1.attainment/??te?nm?nt/n.达到;成就,造诣2.take root⽣根;开始;建⽴3.fraternal/fr??t??nl/adj.兄弟般的,亲如⼿⾜的4.identical/a??dent?kl/adj.同⼀的,完全相同的5.aptitude/??pt?tju?d/n.天资,天赋6.cognitive/?k?ɡn?t?v/adj.认知的,认识的7.disprove/d?s?pru?v/vt.证明……是错的8.subdue/s?b?dju?/vt.征服;抑制,克制9.postulate/?p?stj?le?t/v.假定,假设Passage8More Than Meets the Mirror:Illusion1Test Links Difficulty Sensing InternalCues2with Distorted3Body-Image(2011.1.4Scientific America)[457words]With all of the New Year’s diet ads claiming you canlose dozens of pounds in seemingly as many days,youprobably are not alone if you looked in the mirror thismorning and saw a less than ideal body.Or maybe you justpicked up a new magazine in which already thin modelshave their remaining flesh scavenged4by Photoshop to make them appear even slimmer.With all of these unrealistic promises and images,it can be hard to gain an accurate sense of one’s own body.But the disjunction5for some people might go deeper than manipulated5photos.A new study shows that the way people perceive their external7appearance is likely linked to how they experience their bodies internally.Researchers found that people who had greater difficulties sensing their own internal bodily states were also more likely to be fooled into believing a rubber hand was part of their own bodies. These results,published online in the issue of Proceedings of the Royal Society B: Biological Sciences,may one day help scientists understand how body image can become so distorted in disorders like body dysmorphia8and anorexia nervosa9,says lead author Manos Tsakiris of Royal Holloway,University of London.“The sense of self is built up from a representation of internal states,”says Hugo Critchley,a professor of psychiatry at the University of Sussex in England who was not involved with the study.“This paper is showing that sensitivity of individuals to their internal state predicts the strength of their self-representation.”Most of the time,the image someone has of their body is pretty close to its external appearance.You may see your thighs10as slightly bigger than they actually are,or your arm muscles as slightly smaller,but the discrepancy11is usually minimal12.In some mental disorders,however,body image can become dramatically distorted.Those who suffer from body dysmorphic disorder think that parts of their bodies are malformed13or grotesque14,even when these supposed flaws are not noticeable to others.In eating disorders such as anorexia nervosa patients continue to think they need to lose weight even as their bodies waste away.Crucial to the formation of body image—pathological15and otherwise—is the integration of external and internal cues.What we see in the mirror and what we feel against our skin melds with16our own internal awareness of our bodies to create an overarching17body image.Scientists have historically focused on how external factors like magazines and fashion models affect the creation of an accurate body image.Tsakiris and his colleagues,however,hypothesized that a person’s internal awareness of his or her body,known as

TEXT ONEBritons’ most searing memories of their encounter with foot-and-mouth disease in 2001 are of the piles of animals slaughtered to try to stop its spread. Such a draconian policy might have been accepted had the disease been controlled quickly. But its ineffectiveness—more than 6m cows, sheep and pigs were culled before the disease was eradicated—led to widespread revulsion and a government rethink.Just as in 2001, if an animal is thought to be infected, its herd will be culled and a quarantine zone set up. But this time, unless the disease is stamped out quickly, animals nearby will also be vaccinated to create a “fire-break” across which it is unlikely to travel. Already 300,000 doses of vaccine have been ordered, so that if government vets decide that slaughter alone is unlikely to be effective, they can start vaccinating straight away.Humans almost never catch foot-and-mouth and it rarely kills the cloven-hooved beasts it affects. But animals produce less milk and meat, so its economic effects are severe. It is also highly contagious: infected livestock produce the virus that causes it in large quantities, and transmit it through saliva, mucus, milk, faeces and even droplets in their breath.Even so, only countries where foot-and-mouth is endemic, as in parts of Latin America, vaccinate all animals. One reason is cost: the disease is caused by a virus with seven main types and tens of sub-types, with a targeted vaccine needed for each strain and shots repeated, perhaps as often as twice a year. It is also because vaccinating damages exports. Places that are free from foot-and-mouth are unwilling to import vaccinated beasts, or fresh meat from them, because they may still carry the disease.The fear of being shut out of foreign markets led to the British government's disastrous foot-dragging over vaccination in 2001. But that same year an outbreak in the Netherlands involving 26 farms was brought under control in just one month by vaccinating 200,000 animals. Though healthy, these beasts then had to be culled so that farmers could return to exporting without restrictions as soon as possible.Not even eternal vigilance on imports can keep a country free of foot-and-mouth disease: the latest outbreak was apparently caused by a breach of bio-security at the Pirbright laboratory complex in Surrey, where government researchers keep the live virus for vaccine research and Merial, an American animal-health company, manufactures vaccine for export. Human action, accidental or deliberate, seems likely to have been involved.Ironically, one reason for eschewing vaccination is that although it provides the best hope of dealing with outbreaks, maintaining the capacity to produce vaccine is itself a risky business. Many earlier episodes of foot-and-mouth in countries normallyfree from the disease have been caused by laboratory escapes; in 1970 a leak from Pirbright's isolation facilities was fortunately contained.1. Which one of the following statements is not TRUE of the foot-and-mouth disease in Briton in 2001?[A] The disease had never been effectively controlled throughout the event.[B] The policy of slaughtering animals to stop the disease spread proved to be a failure.[C] The slaughtering policy was arousing discontent among the public in Britons.[D] The government failed to take immediate actions of creating fire-break around the infected livestock.2. The new policy is different from the policy in 2001 in the following aspects except_____[A] the piles of animals will not be slaughtered as in 2001.[B] animals near the infected herb will be injected with vaccine.[C] a belt of quarantine with vaccinated animals will be erected.[D] it is paying more attention to prevention of the outbreak of the epidemic.3.Only a few countries have all of their animals injected with vaccines because of the following reason except_____[A] it is unnecessary to vaccinate all the animals in counties in which there are little chances of infecting foot-and-mouth.[B] the cost of vaccines against all types of the virus causing the disease is very high.[C] vaccinated animals are less welcomed by importing countries.[D] the vaccine cost will be rising as types of virus causing the disease are increasing. 4.Though vaccinated animals were free from the foot-and-mouth in Britain and Netherlands in 2001, they were still slaughtered because_____[A] they may be more likely to infect the virus than the healthy ones.[B] the exporting restrictions were too strict to let these animals pass the custom.[C] the farmers were afraid of being deprived of the exporting right.[D] the government wanted to regain the former status of exporting animals.5.The outbreak of foot-and-mouth disease may be a result of the following situations except_____[A] animals being wrongly or incompletely injected with vaccination.[B] importing animals from the countries with the foot-and-mouth-disease.[C] leak of the virus during the research experimentation.[D] malicious actions by some people with particular purpose.篇章剖析:这篇文章介绍了应对英国口蹄疫的一些情况。

Answer the questions below each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET. (40 points) Text 1 First two hours , now three hours—this is how far in advance authorities are recommending people show up to catch a domestic flight , at least at some major U.S. airports with increasingly massive security lines. Americans are willing to tolerate time-consuming security procedures in return for increased safety. The crash of Egypt Air Flight 804,which terrorists may have downed over the Mediterranean Sea ,provides another tragic reminder of why. But demanding too much of air travelers or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on Americans’ economic and private lives, not to mention infuriating. Last year, the Transportation Security Administration (TSA) found in a secret check that undercover investigators were able to sneak weapons---both fake and real—past airport security nearly every time they tried .Enhanced security measures since then, combined with a rise in airline travel due to the improving Chicago’s O’Hare International .It is not yet clear how much more effective airline security has become—but the lines are obvious. Part of the issue is that the government did not anticipate the steep increase in airline travel , so the TSA is now rushing to get new screeners on the line. Part of the issue is that airports have only so much room for screening lanes. Another factor may be that more people are trying to overpack their carry-on bags to avoid checked-baggage fees, though the airlines strongly dispute this. There is one step the TSA could take that would not require remodeling airports or rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be a win-win for travelers and the TSA. Passengers who pass a background check are eligible to use expedited screening lanes. This allows the TSA wants to enroll 25 million people in PreCheck. It has not gotten anywhere close to that, and one big reason is sticker shock. Passengers must pay $85 every five years to process their background checks. Since the beginning, this price tag has been PreCheck’s fatal flaw. Upcoming reforms might bring the price to a more reasonable level. But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways. The TSA cannot continue diverting resources into underused PreCheck lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work. 21. The crash of Egypt Air Flight 804 is mentioned to______. [A] stress the urgency to strengthen security worldwide [B] explain American’s tolerance of current security checks [C] highlight the necessity of upgrading major U.S. Airports [D] emphasize the importance of privacy protection 【答案】B 【解析】答案为B。

考研时文阅读(17A)(2009-04-04 21:21:15)转载标签:分类:阅读篇考研时文阅读黄涛杂谈篇章分析本文是一篇说明文,主要介绍了两位博士对午睡和健康关系的一项最新研究。

第一段提出了有关午睡的话题,并以一些名人的午睡特点来加以例证,接着介绍了纳斯卡和特里克伯罗斯所进行的研究,说明午睡可以延长人的生命;第二段进一步详细地阐述其研究的结果;第三段作者驳斥了地中海饮食可能影响实验结果可信度的说法;在第四段里,特里克伯罗斯博士建议人们为了健康尽量午睡。

Sloth(怠惰, 懒惰) may be seen as a sin, but some of history's most accomplished men were fond of lounging around. Leonardo da Vinci enjoyed napping. So did Albert Einstein and Winston Churchill. Richard Buckminster Fuller advocated taking 30-minute naps every six hours. No one has yet proved a correlation between napping and artistic brilliance or professional success, but an intriguing study published this week claims to find a link between daytime siestas and good health. A team of researchers led by Androniki Naska and Dimitrios Trichopoulos of Harvard's School of Public Health followed over 23,000 Greek patients with no history of cancer or stroke, for an average of six years. Their conclusion: napping just might save your life.The study found that the group of adults who took 30-minute siestas at least three times a week had a third fewer deaths from heart disease than an equivalent group who did not sleep at all during the day. The benefit was greater for men than for women. It was also greater for working males than for those who had retired.However, a number of previous studies done in the Mediterranean and in parts of Central America (where siestas remain common) have come up with conflicting results, but Dr. Naska and Dr. Trichopoulos argue that those studies have often been flawed. The subjects in some, for example, had survived heart attacks and may therefore have benefited more from napping than healthy individuals do.Given that all of the subjects of this new study were Greeks; could themuch-celebrated Mediterranean diet deserve credit, rather than the siestas? The firm answer from Dr Trichopoulos is “No”. And he is in a good position to say so, for it was he who did the pioneering research that put olive oil and a plant-based diet on the scientific map in the first place. Unlike some other nap studies, his was controlled for diet, smoking, exercise and other relevant variables. The earlier findings about the benefits of the Mediterranean diet are confirmed, he says, and napping seems to help on top of that.Before buying a sofa for the office, however, it might be wise to consider the possibility of selection bias. Dr Trichopoulos concludes that “Type A” personalities, whose hard-working lives may make them prone to heart attacks, are also much less likely to take naps during the day. That bias might be distorting the study's results. Even so, he advises, “Take a nap if you can.”参考译文懒惰也许会被人们认为是一种罪过,但是历史上一些最成功的人士却喜欢悠闲懒散的生活。

列奥纳多·达芬奇喜欢午睡,阿尔伯特爱因斯坦和温斯顿丘吉尔也一样喜欢午睡。

里查德巴克明斯行福勒提倡每隔6个小时就小睡30分钟。

没有人能够证明午睡与杰出的艺术才能或者事业上的成功有相互关系,但是本周一份引人入胜的研究报告声称发现了日间午睡与健康之间的一种联系。

一个由安德罗尼基·纳斯卡和哈佛公共卫生学院的特里克伯罗斯所领导的研究小组对23,000名没有癌症或者中风记录的希腊病人,进行了长达6年的研究,该研究结果表明:午睡有可能延长人的生命。

这项研究发现,那些每周至少午休3次,且每次午睡至少30分钟的成人组与日间从不午休的成人组相比,患心脏病致死的概率低了1/3。

男性从午睡中的获益比女性更加明显。

上班的男性比退休人士的获益更为明显。

但是,在午休仍然普遍的地中海地区和中美洲的部分地区曾进行过的一些研究得到的却是与此矛盾的结果,不过纳斯卡博士和特里克伯罗斯博士认为这些研究都存在问题。

比如,一些曾经有过心脏病发作史的研究对象从午睡中的获益相对于那些健康人要明显得多。

鉴于所有的研究对象都是希腊人,那些影响因素是否是驰名的地中海饮食而不是午休呢?特里克伯罗斯博士坚定地回答说“不”。

他的回答是令人信服的,因为正是他开创性地将橄榄油和以素食为主的饮食放到科学领域内来进行研究。

与其它关于午休研究不同的是,他的研究控制了饮食、吸烟、运动和其他相关的变量。

他说,早前关于地中海饮食益处的研究已经得到了肯定,而午睡在饮食的基础上也起到了最为重要的作用。

在办公室添臵沙发之前,最好还是先考虑一下选择性偏见的可能性。

特里克伯罗斯博士认为那些辛勤工作从而易发心脏病的“A型”个性的人,在白天小睡比较少。

这些偏见也许会与研究报告的结果相矛盾。

即便如此,特里克伯罗斯博士还是建议,“如果可以的话就小睡一会吧”。

第一段通过一个最新研究来引出人们越来越肥胖这一话题;第二段用具体数据进一步阐述了这一研究结果;第三段论述了朋友关系对于肥胖的不同影响及其原因;第四段指出家庭关系和兄弟姐妹关系对肥胖有影响,但并不重要,真正重要的原因是其社会标准。

最后一段提出人与人之间的这种相互影响关系也同样适用于减肥。

Researchers from Harvard and the University of California, San Diego, reviewed a database of 12,067 densely interconnected people who had all participated in a major American heart study between 1971 and 2003. It was that information that the NEJM authors mined to explore obesity in the context of a social network.From their analysis, when a study participant's friend became obese, that first participant had a 57% greater chance of becoming obese himself. In pairs of people in which each identified the other as a close friend, when one person became obese the other had a 171% greater chance of following suit. James Fowler, a political scientist at UC San Diego says that it's not just that people who share similar lifestyles become friends. For one thing, geographic distance between friends in the study seemed to have no impact: friends who lived a 5-hour drive apart and saw each other infrequently were just as influenced by each other's weight gains as those who lived close enough to share weekly take-out meals or basketball games.The best proof that friendship caused the weight gain, says Fowler, is that people were much more likely to pattern their own behavior on the actions of people they considered friends — but the relationship didn't work in the other direction. If you had named another person as a friend, and your friend became obese, then you were more than 50% more likely to get fat too. But if your friend had not named you as a mutual friend, and you became obese, it would have no significant impact on your friend's weight.Spouses share meals and a backyard, but the researchers found a much smaller risk of gaining weight—a 37% increase—when one spouse became obese. Siblings share genes, but their influence, too, was much smaller, increasing each other's risk 40%. Fowler believes the effect has much more to do with social norms: whom we look to when considering appropriate social behavior. Having fat friends makes being fat seem more acceptable.Fowler and Christakis say that the contagion-effect should hold just as much for weight loss as it does for weight gain. "I would hope this influences individuals to get friends and families involved in decisions about health," Fowler says. After all, he says, a weight-loss plan may be more effective if the people closest to you are on a diet. And, if you're successful, your good health will help others achieve a healthy weight too. The impact extends not just to your friends; it turns out — but also to your friends' friends, and even to their friends.参考译文根据7月26日出版的《新英格兰医学杂志》,肥胖不仅越来越多,而且它会像感冒一样, 在人与人之间传播。
