2013年12月英语六级选词填空习题及答案(1)A novel way of making computer memories, using bacteria　FOR half a century, the (1)__________of progress in the computer industry has been to do more with less. Moore's law famou observes that the number of transistors which can be crammed into a given space (2)__________ every months. The amount of data that can be stored has grown at a similar rate. Yet as (3)________ get smaller, making them gets harder and more expensive. On May 10th Paul Otellini, the boss of ntel, a big American chipmaker, put the price of a new chip factory at around $10 billion. Happily hose that lack Intel's resources, there may be a cheaper option—namely to mimic Mother Nature, has been building tiny (4)__________, in the form of living cells and their components, for billions of years, and has thus got rather good at it. A paper published in Small, a nanotechnology journal , set out the latest example of the (5)__________. In it, a group of researchers led by Sarah Staniland at University of Leeds, in Britain, describe using naturally occurring proteins to make arrays of tiny magnets, similar to those employed to store information in disk drives. The researchers took th 6)__________ from Magnetospirillum magneticum, a bacterium that is sensitive to the Earth's magnet ield thanks to the presence within its cells of flecks of magnetite, a form of iron oxide. Previous w has isolated the protein that makes these miniature compasses. Using genetic engineering, the team managed to persuade a different bacterium—Escherichia coli, a ubiquitous critter that is a workhorse of biotechnology—to (7)__________ 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 solutio containing the protein, allowing it to bind to the treated squares, and dunked the whole lot into a heated 8)__________ 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 he bacterial protein. In principle, each of these magnetic domains could store the one or the zero o bit of information, according to how it was polarised. Getting from there to a real computer memor would be a long road. For a start, the grains of magnetite are not strong enough magnets to make a useful memory, and the size of each domain is huge by modern computing (9)__________. But Dr Staniland reckons that, with enough tweaking, both of these objections could be dealt with. The 10)__________ of this approach is that it might not be so capital-intensive as building a fab. Grow hings does not need as much kit as making them. If the tweaking could be done, therefore, the resu might give the word biotechnology a whole new meaning. A) components B) advantage C) standards D) compliments E) essence F) inspiration G) disadvantage H) doubles I) solution J) resolution K) devices L) manufacture M) spirit N) product O) technique2013年12月英语六级选词填空习题及答案(2)juicy Apple ALTHOUGH he is still (1)__________ things up at Dell, an ailing computer-maker, n has found time to tilt at another tech titan.

Mr Icahn’s intentions, however, are crystal clear: he wants the consumer-electronics behemoth to e s to return some of its whopping $147 billion of cash and marketable securities to shareholders. Mr o after more money at Dell, where he has been lobbying with allies against a (3)__________ buy-out p orward by Michael Dell, the firm’s founder, and Silver Lake, a private-equity firm. His pressing has alr ed the buy-out group to raise its initial offer by over $350m, to $24.8 billion and he has taken his_________ to the courts in a bid to extract an even higher price. Other tech firms have been attracti tion of activist investors too. Earlier this year ValueAct Capital, an investment fund, said it had built up on stake in Microsoft.

And Elliott Management, a hedge fund, has been lobbying for change at NetA storage firm that it thinks could do more to improve returns to (7)__________. One reason tech fir found themselves in activists’ crosshairs is that, like Apple, some built up big cash piles during the omic downturn and have been slow to use the money. Financiers hope to get them to loosen their purse gs faster and to pocket some of the cash. Mr Icahn wants Apple to increase and (8)__________ a share programme that is currently set to return $60 billion to shareholders by the end of 2015. Another r ech firms make tempting targets for shareholder activists is that swift changes in technologies can trip the mightiest. Witness the case of Microsoft, which ruled the roost during the personal-computer era b gled to adapt to a world in which tablets and smartphones are all the rage. Investors hope to mint mone ing companies to change more rapidly in response to such upheavals in their markets. The rewards ubstantial.

About 61% of the caloric increase comes from the alcohol itself. Men also report eating hi ts of saturated fats and meat, and less fruit and milk, on those days than on days when they aren't drink dy showed. Women fared a bit better, taking in an extra 300 calories on moderate-drinking days, f ohol and eating fattier foods. But women's increase in calories from additional eating wasn't statisticall cant, the study said. 'Men and women ate less healthily on days they drank alcohol,' said Rosalind w, an epidemiologist with the federal National Institute on Alcohol Abuse and Alcoholism and lead aut dy. 'Poorer food choices on drinking days have public-health (4)__________,' she said. The findings il with controlled lab studies in which (5)__________ generally eat more food after consuming alcohol chers suggest that alcohol may enhance 'the short-term rewarding effects' of consuming food, accordin eport in the journal Physiology & Behavior that reviewed previous studies on alcohol, appetite and obe other studies have pointed to a different trend. Moderate drinkers gain less weight over time than either drinkers or people who abstain from alcohol, particularly women, this research has shown. Moderateg is (6) __________having about two drinks a day for men and one for women. 'People who gain eight are moderate drinkers, regardless of [alcoholic] beverage choice,' said Eric Rimm, an associateor of epidemiology and nutrition at Harvard Medical School and chairman of the 2010 review of alcoh eral dietary (7)__________. The weight-gain difference is modest, and 'starting to drink is not a weigh e said. The various research efforts form part of a long-standing (8)__________ about how alcoho people's appetites, weight and overall health. Researchers say there aren't simple answers, and suggest uals' metabolism, drinking patterns and gender may play a role. Alcohol is 'a real wild card when it c ght management,' said Karen Miller-Kovach, chief scientific officer of Weight Watchers International. calories per gram, alcohol is closer to fat than to carbohydrate or protein in caloric content, she said. Al o lower restraint, she notes, causing a person to become more (9)__________ with what they're eating. ch bolstering the role of moderate drinking in helping to control weight gain was published in 2004 in t Obesity Research. That study followed nearly 50,000 women over eight years. An earlier study, publi American Journal of Epidemiology in 1994, followed more than 7,000 people for 10 years and found th ate drinkers gained less weight than nondrinkers. Studies comparing changes in waist circumference am nt 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 l, their heart rate increases so they burn more calories in the following hour. 'It's a modest amount,' h you take an individual that eats 100 calories instead of a glass of wine, the person drinking the glass of ve a slight increase in the amount of calories burned.'A indulgent B participants C debate D considered E contributes F contest G guidelines H protective I moderate J index K implications L considerate M :additional N experienced O owes2013年12月英语六级选词填空习题及答案(4)Nearly half the (1)__________ believes UFOs could be a (2) __________of extraterrestrial ation.
