问题     Teenagers are paradoxical. That’s a mild and detached way of saying something that parents often express with considerably stronger language. But the paradox is scientific as well as personal. In adolescence, helpless and dependent children who have relied on grown-ups for just about everything become independent people who can take care of themselves and help each other. At the same time, once cheerful and compliant children become rebellious teenage risk-takers.
    A new study published in the journal Child Development, by Eveline Crone of the University of London and colleagues, suggests that the positive and negative sides of teenagers go hand in hand. The study is part of a new wave of thinking about adolescence. For a long time, scientists and policy makers concentrated on the idea that teenagers were a problem that needed to be solved. The new work emphasizes that adolescence is a time of opportunity as well as risk.
    The researchers studied "prosocial" and rebellious traits in more than 200 children and young adults, ranging from 11 to 28 years old. The participants filled out questionnaires about how often they did things that were altruistic and positive, like sacrificing their own interests to help a friend, or rebellious and negative, like getting drunk or staying out late.
    Other studies have shown that rebellious behavior increases as you become a teenager and then fades away as you grow older. But the new study shows that, interestingly, the same pattern holds for prosocial behavior. Teenagers were more likely than younger children or adults to report that they did things like unselfishly help a friend.
    Most significantly, there was a positive correlation between prosociality and rebelliousness. The teenagers who were more rebellious were also more likely to help others. The good and bad sides of adolescence seem to develop together.
    Is there some common factor that underlies these apparently contradictory developments? One idea is that teenage behavior is related to what researchers call "reward sensitivity. " Decision-making always involves balancing rewards and risks, benefits and costs. "Reward sensitivity" measures how much reward it takes to outweigh risk.
    Teenagers are particularly sensitive to social rewards—winning the game, impressing a new friend, getting that boy to notice you. Reward sensitivity, like prosocial behavior and risk-taking, seems to go up in adolescence and then down again as we age. Somehow, when you hit 30, the chance that something exciting and new will happen at that party just doesn’t seem to outweigh the effort of getting up off the couch.
It can be learned from the last two paragraphs that teenagers________
选项 A、overstress their influence on others
B、care a lot about social recognition
C、become anxious about their future
D、endeavor to live a joyful life
答案B
解析 推断题。由题干的 the last two paragraphs定位到最后两段。其中提到青少年对赢得比赛、给新朋友留下印象、让男孩注意到自己等社交奖励特别敏感，也就是说青少年更在意社会认可，故正确答案为B。文中提到青少年时期，孩子们会在意赢得比赛、给新朋友留下印象等事情，这可以说青少年在乎自己对别人的影响，但是并没有overstress的意思，选项A属于过度推断，故排除。选项C和 D 文中均未提及，属于无中生有，故均排除。
