六级选词填空练习题书Questionstoare based on the following passage.I’ve twice been to college admissions wars, and as I survey the battle field, something different is happening. It’s one upmanship among parents. We see our kids collegeas trophies attesting to how well we’ve raised them. But we can’t acknowledge that our obsession is more about us than them. So we’ve contrived variousthat turn out to be haft truths, prejudices or myths.We have a full blown prestige panic; we worry that there won’t be enough trophies to go around. Fearful parents urge their children to apply to more schools than ever.Underlying the hysteria is the belief that scarcedegrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All that’s9and mostly wrong. Selective schools don’t systematically 0 better instructional approaches than less-selective schools. Some do; some don’t. On two measures--professors feedback and the number of essayexams--selective schools do slightly worse.By some studies, selective schools do enhance their graduates lifetime earnings. The gain is reckoned at percent to percent for every 100 point increase in a school’s average SAT scores. But even this advantage is probably a1 fluke . A well kno,vn study by Princeton economist Alan Krueger and Stacy Berg Dale of Mathematica Policy Research examined students who got into highly selective schools and then went elsewhere. They earned just as much as graduates from other schools.Kids count more than their colleges. Getting into Yale may4intelligence, talent and ambition.But it’s not the only indicator and,, its significance is declining. The reason: so many similar people go elsewhere. Getting into co llege isn’t life’s only competition. In the next competition--the job market, graduate school--the results may change. Old boy networks are breaking down. Krueger studied admissions to one top Ph.D. program. High scores on the Graduate Record Exam helped explain who got in; Ivy League degrees didn’t.So, parents, lighten up. The stakes have been vastly exaggerated. Up to a point, we canour pushiness. America is a competitive society; our kids need to adjust to that. But too much pushiness can be4. The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment. One study of students0 years out found that, other things being equal, graduates of highly selective-schools experienced more job dissatisfaction.

Previous work has isolated the protein that makes these miniature compasses. Using genetic engineering， the team managed to persuade a different bacterium—Escherichia coli， a ubiquitouscritter that is a workhorse of biotechnology—to __________ this protein in bulk.Next，they imprinted a block of gold with a microscopic chessboard pattern of chemicals.Half the squares contained anchoring points for the protein.The other half were left untreated as controls. They then dipped the gold into a solution containing the protein， allowing it to bind to the treated squares， and dunked the whole lot into a heated __________ of iron salts.After that， they examined the results with an electron microscope.Sure enough，groups of magnetite grains had materialised on the treated squares， shepherded into place by the bacterial protein.In principle， each of these magnetic domains could store the one or the zero of a bit of information，according to how it was polarised.Getting from there to a real computer memory would be a long road.For a start， the grains of magnetite are notstrong enough magnets to make a useful memory， and the size of each domain is huge by modern computing __________.But Dr Staniland reckons that，with enough tweaking， both of these objections could be dealt with. The __________ of this approach is that it might not be socapital-intensive as building a fab.Growing things does not need as much kit as making them.If the tweaking could be done， therefore， the result might give the word biotechnology a whole new meaning.new meaning.A) components B) advantageC) standards D) complimentsE) essence F) inspirationG) disadvantage H) doublesI) solution J) resolutionK) devices L) manufactureM) spirit N) productO) techniqueNice juicy AppleALTHOUGH he is still __________ things up at Dell，an ailingcomputer-maker， Carl Icahn has found time to tilt at another tech titan. On August 13th the veteran shareholder activist __________that he had built up a stake in Apple， though he stayed mum about exactly how many shares he had bought. Mr Icahn’s intentions，however，are crystal clear：he wants the consumer-electronics behemoth to expand plans to return some of its whopping $14billion of cash and marketable securities to shareholders.Mr Icahn is also after more money at Dell， where he has been lobbying with allies against a __________ buy-out plan put forward by Michael Dell， the firm’s founder， and Silver Lake， a private-equity firm. His pressing has already forced the buy-out group to raise its initial offer by over $350m， to $24.billion and he has taken his __________ to the courts in a bid to extract an even higher price.Other tech firms have been attracting the attention of activist investors too. Earlier this year ValueAct Capital， an investment fund， said it hadbuilt up a $2billion stake in Microsoft. Jaguar Financial， a Canadian bank， has been __________ fresh thinking at troubled BlackBerry， which announced on August 12th that it is exploring various __________options，including alliances and a possible sale. And Elliott Management， a hedge fund， has been lobbying for change at NetApp， a data-storage firm that it thinks could do more to improve returns to __________.One reason tech firms have found themselves in activists’ crosshairs isthat，like Apple， some built up big cash piles during the economic downturn and have been slow to use the money. Financiers hope to get them to loosen their purse-strings faster and to pocket some of the cash. Mr Icahn wants Apple to increase and __________ a share buy-back programme that is currently set to return $60 billion to shareholders by the end of015.Another reason that tech firms make tempting targets for shareholder activists is that swift changes in technologies can trip up even the mightiest. Witnessthe case of Microsoft， which ruled the roost during the personal-computer era but has struggled to adapt to a world in which tablets and smartphones are all the rage. Investors hope to mint money by pushing companies to change more rapidly in response to such upheavals in their markets.The rewards can be substantial. Egged on by Third Point，an activist hedge fund，Yahoo __________Marissa Mayer as its new chief executive in July012. By the time she celebrated a year in the job last month， the troubled web giant’s share price had risen by over0%. In July the hedge fund sold a big chunk of shares back to Yahoo. Mr Icahn thinks Apple’s share price， which closed at $49on August 14th， could soar too if the firm follows his advice on buy-backs. He tweeted this week that he had had a “nice __________” with Tim Cook， Apple’s boss， about his idea， though he did not say what Mr Cook thought of it. If Apple drags its feet， expect things to turn nasty.A） shareholders B） strategicC） communication D） battleE） conversation F） encouragingG） exciting H） stirringI） appointedJ） raceK） revealed L） methodM） accelerate N） proposedO）It isn’t just the beer that __________ to beer bellies. It could also be the extra calories， fat and unhealthy eating choices that may comewith __________drinking.A recent study found that men consume an __________33calories on days they drink a moderate amount of alcohol. About1% of the caloric increase comes from the alcohol itself. Men also report eating higher amounts of saturated fats and meat， and less fruit and milk，on those days than on days when they aren’t drinking，the study showed.Women fared a bit better， taking in an extra00 calories on moderate-drinking days， from the alcohol and eating fattier foods. But women’s increase in c alories from additional eating wasn’t statistically significant， the study said.‘Men and women ate less healthily on days they drank alcohol，’ said Rosalind Breslow，an epidemiologist with the federal National Institute on Alcohol Abuse and Alcoholism and lead author of the study. ‘Poorer food choices on drinking days have public-health __________，’ she said.The findings dovetail with controlled lab studies in which __________ generally eat more food after consuming alcohol. Researchers suggest that alcohol may enhance ‘the short-term rewarding effects’ of consumingfood， according to a010 report in the journal Physiology & Behavior that reviewed previous studies on alcohol， appetite and obesity.But other studies have pointed to a different trend. Moderate drinkers gain less weight over time than either heavy drinkers or people who abstain from alcohol， particularly women， this research has shown. Moderate drinking is __________having about two drinks a day for men and one for wome n. ‘People who gain the least weight are moderate drinkers，regardless of[alcoholic] beverage choice，’ said Eric Rimm，an associate professor ofepidemiology and nutrition at Harvard Medical School and chairman of the010 review of alcohol in the federal dietary __________. The weight-gain difference is modest，and ‘starting to drink is not a weight-loss diet，’ he said. The various research efforts form part of a long-standing __________ about how alcohol affects people’s appetites， weight and overall health. Researchers say there aren’t simple answers，and suggest that individuals’ metabolism，drinking patterns and gender may play a role.Alcohol is ‘a real wild card when it comes to weight management，’ said Karen Miller-Kovach， chief scientific officer of Weight Watchers International. At seven calories per gram， alcohol is closer to fat than to carbohydrate or protein in caloric content，she said. Alcohol tends to lower restraint， she notes，causing a person to become more __________ with what they’re eating.Research bolstering the role of moderate drinking in helping to control weight gain was published in00inthe journal Obesity Research. That study followednearly0，000 women over eight years. An earlier study，published in the American Journal of Epidemiology in 1994， followed more than，000 people for 10 years and found that moderate drinkers gained less weight than nondrinkers. Studies comparing changes in waist circumference among different groups have yielded similar results.Dr. Rimm said it isn’t clear why moderate drinking may be __________ against typical weight gain，but it could have to do with metabolic adjustments. After people drink alcohol， their heart rate increases so they burn more calories in the following hour.‘It’s a modest amount，’ he said. ‘But if you take an individual that eats 100 calories instead of a glass of wine， the person drinking the glass of wine will have a slight increase in the amount of calories burned.’A：indulgent B：participantsC：debate D：consideredE：contributesF：contestG：guidelines H：protectiveI：moderate J：indexK：implications L：considerateM：additional N：experiencedO：owesNearly half the __________ believes UFOs could be a __________of extraterrestrial visitation.A HuffPost/YouGov poll reveals thatpercent of adults in the United States are open to the idea that alien spacecraft are observing our planet -- and justpercent outright __________ the idea.The poll was seen as vindication from the community of UFO researchers who often feel they are laughed off by government officials.“It’s always been intriguing to me how we act as though only kooks and quacks and little old ladies in tennis shoes b elieve in flying saucers. And it’s never been true， at least for0 or0 years，” said former nuclear physicist StantonFriedman，who was the original civilian investigator of the events surrounding the __________Roswell， NM， UFO crash of 1947.Friedman is very outspoken on the idea that someUFOs are __________ controlled extraterrestrial vehicles.“The believers are far more quiet， but far more on the side of reality，”Friedman told The Huffington Post. “When you look at the polls， it’s clear. And I see the benefit of that，__________，because I’ve only had 11 hecklers 1.One in five US workers regularly attends after-work drinks with co-workers, where the most common range from bad-mouthing another worker to kissing a colleague and drinking too much, according to a study on Tuesday.Most workers attend so-called happy hours towith colleagues, although 1percent go to hear the latest office gossip and 1percent go because they feel obliged, said the survey conducted for , on online job site.As to what happens when the after-work drinks flow, 1percent reported bad-mouthing a colleague, 10 percent shared a secret about a colleague, percent kissed a colleague and percent said they drank too much andacted . percent said they had shared a secret about the company, and percent to singing karaoke.While1 percent of those who attend say happy hours are good for ,percent said attending had not helped them get to someone higher up or get a better position.

Overall,1 percent of workers attend happy hours with co-workers and, of those,a quarter go at least once a month.The survey was online by Harris Interactive on behalf of CareerBuilder, com among,98full-time employees.KEY: F M A K N L E H C IIf it were only necessary to decide whether to teach elementary science to everyone on a mass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple. The public school, however, has no such choice, for the job must be on at the same time. Because we depend soupon science and technology for our progress, we must produce in manyfields. Because we live in a democratic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, tothe work of experts. The public school must educate both producers and users of scientific services.In education, there should be a good balance among the branches of knowledge that contribute to effective thinking and wise judgment. Such balance isby too much emphasis on any one field. This question of balance involves not only the relation of the natural sciences, the social sciences, and the arts but also relative among the natural sciences themselves.Similarly, we must have a balance between current and knowledge. The attention of the public isdrawn to new possibilities in scientific fields and the discovery of new knowledge; these should not be allowed to turn our attention away from the sound, materials that form the basis of courses for beginners.KEY: F N B M OH K C I EYears ago, doctors often said that pain was a normal part of life. In particular, when older patients ofpain, they were told it was a natural part of aging and they would have to learn to live with it.Times have changed. Today, we take pain . indeed, pain is now considered the fifth vital, as important as blood pressure, temperature, breathing rate and pulse in person?s well-being. We know that chronic pain can disrupt a person?s life, causing problems that now depend upon physicians who in pain medicine. Not only do we evaluate the cause of the pain, which can help us treat the pain better, but we also help provide comprehensive therapy for depression and other psychological and social to chronic pain. Such comprehensive therapy often the work of social workers, psychiatrists and psychologists, as well as specialists in pain medicine.for pain management has led to a wealth of innovative treatments which are more effective and with fewer side effects than ever before. Decades ago, there were only aof drugs available, and many of them caused side effects in older people, including dizziness and fatigue. This created a double-edged sword: the medications helped relieve the pain but caused otherproblems that could be worse than the pain itself.KEY;L G I D OF B M J C4As war spreads to many corners of the globe, children sadly have been drawn into the center of conflicts.
