    1、专业英语八级(改错)模拟试卷 106及答案与解析 一、 PART IV PROOFREADING & ERROR CORRECTION (15 MIN) Directions: Proofread the given passage. The passage contains TEN errors. Each indicated line contains a maximum of ONE error. In each case, only ONE word is involved. You should proofread the passage and correct it in the

(2)For a missing word, mark the position of the missing word with a “ “ sign and write t 0 Making your way gloomily to the airport after an action-packed holiday, it i

    3、s easy to feel the days have flown by all too quick. But 【 M1】 _ there is no need to worry about because once you return to the daily 【 M2】 _ grind your break will suddenly seem like it lasted for a lifetime. So say psychologists who believe that the effect is thanks to the 【 M3】 _ different methods

    4、 the brain uses to judge the passage of time. Learning to manipulate our perception of time could make our lives feel fuller and reassure these who feel that the years slip by faster as 【 M4】 _ they grow older. In a normal fortnight an ordinary person only accumulates 【 M5】 _ between six to nine new

    5、 memories because so much of what we do 【 M6】 _ is routine. But on the holiday we can build up that number of 【 M7】 _ memories in a single day because everything we experience is new, meaning that when we look back it will seem to have lasted much longer than it really did. The same happens because

    6、we get older and time starts to speed 【 M8】 _ up. There are fewer memories of new things, and we do the same things over and over. 【 M9】 _ People who complain that years seem to whizz past with increasing speed could slow things down by making the most of our 【 M10】 _ weekends and breaking up their

    7、daily routine. Taking a different route to work, getting off the bus a stop early or avoiding having the same sandwich for lunch every day could make life seem a little slower. 1 【 M1】 2 【 M2】 3 【 M3】 4 【 M4】 5 【 M5】 6 【 M6】 7 【 M7】 8 【 M8】 9 【 M9】 10 【 M10】 10 It is not, by no means, the worlds old

What is unusual about IBM, which celebrates its 100th birthday this week, is that it has been so successful and so long in the fa

    9、st-moving field of 【 M3】 _ technology. How has it done it? IBMs secret is that it is built around an idea that transcends any special product or technology. Its strategy is to package technology 【 M4】 _ for use by businesses. At first this meant making punch-card tabulators, but IBM moved on to magn

    10、etic-tape systems, mainframes, PCs, and most recently services and consulting. Building a company around an idea, other than a specific technology, makes it easier to 【 M5】 _ adapt when industry platform shifts occur. True, IBMs longevity is also due, in parts, to dumb luck. It 【 M6】 _ almost came u

    11、nstuck early because its bosses were hesitant to 【 M7】 _ abandon punch cards. And it had a near-death experience in 1993 since its bosses realized that the best way to package technology for 【 M8】 _ use by businesses was to focus on services. An elegant organizing idea is of use if a company cannot

    12、come up with good products or 【 M9】 _ services, and if it has clueless bosses. But on the basis of this simple 【 M10】 _ formula that a company should focus more on an idea than a technology, which of todays technology giants might still be standing tall a century after their founding? 11 【 M1】 12 【

In September he announced that he built a better mouse by altering a gene that 【 M1】 _ affects learning and memory. A s

    14、imilar process of gene manipulation might conceivably be used one day to boost up 【 M2】 _ intelligence in humans. The secret lies in a feature of brain cells which called the 【 M3】 _ nomda receptor, which Tsien likes to a cylindrical tube or window 【 M4】 _ that mediates the flow of information. When

    15、 the window is open, chemicals called neurotransmitters flow through easily and memory is registered or stored. Tsien noticed that the receptor 【 M5】 _ worked more efficiently when teamed with the gene NR2B, so he introduced extra NR2B genes into a batch of fertilized mouse eggs. In a normal mouse,

    16、the memory window is open in just 【 M6】 _ 150-thousandths of a second. In Tsiens specifically engineered 【 M7】 _ mice, the window opens for 250-thousandths of a second, long enough to make a remarkable impression in memory retention. 【 M8】 _ When he pitted his mice with common mice, they won paws do

    17、wn. 【 M9】 _ Ordinary mice could recognize a Lego block for 12 hours, but smart mice could remember the block for up to three days. “Thats a profound enhancement,“ Tsien says. Can it be done with humans? Maybe, so genetic engineering 【 M10】 _ will have to make some extraordinary advances first. And s

    18、ome thorny ethical issues will have to be resolved. Meanwhile, Tsien promises to keep his furry little geniuses locked up in a lab, far from your larder. “Otherwise,“ he says, “you might need a smart cat or a smart mousetrap to catch them.“ 21 【 M1】 22 【 M2】 23 【 M3】 24 【 M4】 25 【 M5】 26 【 M6】 27 【 M7】 28 【 M8】 29 【 M9】 30 【 M10】 专业英语八级(改错)模拟试卷 106答案与解析
