Anyone who doubts that children are born with a healthy amount of ambition need spend only a few minutes with a baby eagerly learning to walk or a headstrong toddler starting to talk. No matter how many times the little ones stumble in their initial efforts, most keep on trying, determined to master their amazing new skill. It is only several years later, around the start of middle or junior high school, many psychologists and teachers agree, that a good number of kids seem to lose their natural drive to succeed and end up joining the ranks of underachievers.
It’s not quite that simple. “Kids can be given the opportunities to become passionate about a subject or activity, but they can’t be forced, ” says Jacquelynne Eccles, a psychology professor at the University of Michigan, who led a landmark, 25-year study examining what motivated first grade students in three school districts. Even so, a growing number of educators and psychologists do believe
A. A sudden lack of motivation is attributed to the student’s failure

C. Looking smart is more important for young people at school

[单项选择]　　Predicting the future is always risky. But it’’s probably safe to say that at least a few historians will one day speak of the 20thcentury as America’’s "Disney era". Today, it’’s certainly difficult to think of any other single thing that represents modem America as powerfully as the company that created Mickey Mouse. Globally, brands like Coca-Cola and McDonald’’s may be more widely known, but neither concludes 20th-century America in quite the same way as Disney. 　　The reasons for Disney’’s success are quite a lot, but ultimately the credit belongs to one person - the man who created the cartoon and built the company from nothing, Walt Disney. Ironically, he could not draw particularly well. But he was a genius in other aspects. In business, his greatest skills were his insight and his management ability. After setting himself up in Hollywood, he single-handedly pioneered the concepts of branding and merchandising -- something his company still does brilliantly today. 　　But what
A. sympathetic.
B. objective.
C. critical.
D. skeptical.
