When we're in trouble, we always turn to our parents for help. But would you like them to hear the conversations you have with your friends in the school playground or in the lunch queue? Social networking sites, such as blogs and micro-blogs, have become extensions（延伸）of the school hallways, so would you add your parents as "friends" and allow them to view your online activities and conversations with friends?
In the past the generation gap included a technology gap, where children were up to date with the latest technology and parents were left behind, content to continue their day-to-day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation（动机）to educate themselves about social networking sites.
These days many people are attracted to social networking sites because they can choose who they have around them. There's also a certain amount of control over privacy（隐私）that we
don't get in real life. Sometimes we feel that privacy is violated（侵犯）when we must accept a "friend" request from a parent or family member.
It's a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand, we don't want to "refuse" their request because that might hurt their feelings or make them feel we have something to hide. On the other hand, if we do accept, then we could have a sense of being watched and no longer feel free to comment or communicate the way we did before.
A recent survey suggested that parents shouldn't take it personally if their children overlook（不理会）their requests. When a teenager overlooks a parent's friend request, it doesn't necessarily mean that he is hiding something, but it could mean that this is one part of his life where he wants to be independent.
Perhaps talking with parents and giving explanations would help soften the blow if you do choose not to add them to your friend list.

语篇解读 本文是一篇议论文。文章介绍了随着社交网站的迅速发展，越来越多的父母意识到它们的重要性，想加孩子为好友，但是对于孩子来说，这是个艰难的选择，接受或者拒绝都会让自己遭遇麻烦。
12. A 细节理解题。根据第二段中的“However, more and more parents are beginning to realize just how important social networks are in their lives.”可知，父母已经意识到社交网站的重要性。故选 A。
13. C 推理判断题。根据第四段中的“On the other hand, if we do accept, then we could have a sense of being watched and no longer feel free to comment or communicate the way we did before.”可知，如果我们接受了父母加为好友的请求，会有被监视的感觉，不再像以前那样随意发表评论或交流。由此可知，青少年拒绝父母好友请求的理由可能是不愿意被父母监视。故选 C。
14. D 代词指代题。根据画线词上文“On the one hand, we don't want to 'refuse' their request”和下文“might hurt their feelings or make them feel we have something to hide”可推知，能让父母觉得感情被伤害，或孩子有所隐瞒的应该是孩子拒绝他们的好友请求，因此 that 指代上文提到的拒绝父母的好友请求。故选 D。
15. B 主旨大意题。通读全文，尤其根据第一段最后一句可知，文章主要围绕父母申请加孩子为好友展开，紧接着下文探讨了随着社交网站的迅速发展，越来越多的父母意识到它们的重要性，想加孩子为好友，但是对于孩子来说，这是个艰难的选择，接受或者拒绝都会让自己遭遇麻烦。故选 B。
