Teenagers are paradoxical.

A new study published in the journal Child Development, by Eveline Crone of the University of Leiden and colleagues, suggests that the positive and negative sides of teenagers go hand in hand.

莱顿大学的埃维琳·克罗内及其同事在《儿童发展》期刊上发表的一项新研究表明，青少年的积极面和消极面是相伴相生的。

For a long time, scientists and policy makers concentrated on the idea that teenagers were a problem that needed to be solved.

长期以来，科学家和政策制定者都专注于这样一种观念：青少年是一个需要解决的问题。

Other studies have shown that rebellious behavior increases as you become a teenager and then fades away as you grow older.

其他研究表明，叛逆行为在人进入青少年时期时会增多，随后随着年龄增长逐渐消退。

Teenagers were more likely than younger children or adults to report that they did things like unselfishly help a friend.

与年龄更小的孩子或成年人相比，青少年更有可能报告自己做过诸如无私帮助朋友之类的事情。

The teenagers who were more rebellious were also more likely to help others.
