阅读下面的短文
I was pushed into writing the "Top ten problems teenagers face" after I attended a school program, where I had the opportunity to interact with many teenagers. Each conversation was only adding one more item to the list of problems.
About two thirds of girls in Grades Nine to Twelve "worry about their appearance." While there were no gender differences in worries about school, girls worry about getting along with parents and what to do when they are older. Girls are proven to worry more about personal problems, romantic relationships, being liked by other kids and being concerned about what kind of person they are. In fact, the only thing boys worry about more than girls is succeeding in their physical activities.
What parents need is to look at ways to help teens and take responsibility for what we are exposing our teens to right now. We cannot afford to ignore the parental duties of bringing them up well from the time they are little. Televisions, computers and other gadgets that they spend most of the time on cannot give them the nurturing that only parents can.
