问题     We’ve long been eager to believe that mastery of a skill is primarily the result of how much effort one has put in. Extensive practice " is probably the most reasonable explanation we have today not only for success in any line, but even for genius," said the behaviorist John B. Watson almost a century ago. In the 1990s K. Anders Ericsson and a colleague at Florida State University reported data that seemed to confirm this view: What separates the expert from the amateur, a first-rate musician or chess player from a wannabe, isn’t talent: it’s thousands of hours of work.
    It’s daunting to imagine putting in that kind of commitment, but we’re comforted nonetheless by the idea that practice is the primary contributor to excellence. That’s true for three reasons:
    1. Common sense. It seems obvious that the more time you spend trying to get better at something, the more proficient you’ll become. Common sense, however, isn’t always correct. Researchers have found that only when " achievement" is defined as rote recall do we discover a strong, linear relationship with time. When the focus is on depth of understanding and sophisticated problem solving, time on task doesn’t predict outcome very well at all—either in reading or math.
    2. Protestant work ethic. Many people simply don’t like the idea that someone could succeed without having paid his or her dues—or, conversely, that lots of deliberate practice might prove fruitless. Either of these possibilities threatens people’s belief in what social psychologists call a "just world".
    3. Nurture over nature. "Innate? Necessarily so!" is what we’ve heard for centuries. Given the tawdry history of biological reductionism(生物还原论), which usually manages to rationalize current arrangements of power as being due to the natural superiority of privileged groups, is it any wonder we remain leery(猜疑的)of attributing success to inherited talent? It’s more egalitarian to declare that geniuses are made, not born. Indeed, that skepticism is bolstered by evidence indicating that students are more likely to embrace learning if they believe their performance results from effort, something under their control, rather than from a fixed level of intelligence that they either possess or lack.
    For many of us, then, Andersson’s conclusion has been deeply reassuring: Practice hard and you’ll do well. But along comes a brand-new meta-analysis, a statistical summary of 157 separate comparisons in 88 recent studies, that finds practice actually doesn’t play nearly as significant a role as we’d like to think. " The evidence is quite clear that some people do reach an elite level of performance without copious(丰富的)practice, while other people fail to do so despite copious practice," wrote Brooke Macnamara, David Hambrick, and Frederick Oswald in Psychological Science. In fact, they calculated that, overall, the amount of deliberate practice in which someone engages explains only 12 percent of the variance in the quality of performance, which means 88 percent is explained by other factors.
    But what other factors? It’s common to assume that if practice matters less than we thought, then inborn ability matters more—as if there are only two contributors to excellence and they’re reciprocally related. That’s not necessarily true, however. The question posed by Macnamara and her colleagues was appropriately open-ended: "We have empirical evidence that deliberate practice, while important, does not largely account for individual differences in performance. The question now is what else matters. " And there are many possible answers. One is how early in life you were introduced to the activity—which, as the researchers explain, appears to have effects that go beyond how many years of practice you booked. Others include how open you are to collaborating and learning from others, and how much you enjoy the activity. That last one—intrinsic motivation—has a huge empirical base of support in workplaces, schools, and elsewhere. We’ve long known that the pleasure one takes from an activity is a powerful predictor of success. For example, one group of researchers tried to sort out the factors that helped third and fourth graders remember what they had been reading. They found that how interested the students were in the passage was thirty times more important than how "readable" the passage was. All of these factors overlap(重叠)and serve as catalysts for one another, which means that even if practice does predict success to some degree, that doesn’t mean it caused the success. Maybe the right question to ask is: Why do some people decide to practice a lot in the first place? Could it be because their first efforts proved mostly successful?
What’s the tone of the passage?
选项 A、Serious and objective.
B、Impartial and impersonal.
C、Casual and convincing.
D、Emotional and persuasive.
答案C
解析 态度题。文章开篇以we开头，使读者对文章产生认同感，接下来，作者还引用了许多研究人员的观点和数据来证明自己的观点：成功的因素很多，由第五段中的反问“Innate?Necessarily so!”，以及文章最后的问题可以看出，作者以轻松的风格创作本文，但他所提供的证据却又十分让人信服，故答案为[C]。
