问题                 Healthy Social Networking Sites Benefit Kids
    The other day I asked somewhat tongue-in-cheek (幽默讽刺的) whether Tom Friedman had ever visited Silicon Valley. Today, I’m wondering if Lady Greenfield has ever used a social networking site.
    She warned that social networking sites are devoid (缺乏) of cohesive (有凝聚性 的) narrative and long-term significance. As a consequence, the mid-21st century mind might almost be characterized by short attention spans, sensationalism, inability to sympathize and a shaky sense of identity.
    I’m not a psychologist, nor am I a parent, so let me start by saying she might be right that these sites are harmful in some cognitive way. But I think she’s wrong to assume social networking is devoid of cohesive narrative and long-term significance. I can see where she’s coming from, but like a lot of people who don’t actually use these sites, she’s missing a fundamental shift from Web 1. 0 chat room days to Web 2. 0 social net-works: Real identity.
    We no longer go to the Internet to interact with some shadowy user name where we pretend to be someone we’re not. Ok, maybe people on Second Life do. But sites like Facebook and Twitter are more about extending your real identity and relationships online. That’s what makes them so addictive: The little endorphin (兴奋) rushes from reconnecting with an old friend, the ability to passively stay in touch with people you care about but don’t have the time to call everyday.
    Facebook makes me a more considerate friend because I now remember people’s birthdays. Via Twitter, my parents and inlaws know everything happening in my life so that when I call home, we have substantive conversations. In dozens of cases, these sites have actually given me a longer narrative.
    Greenfield may well have a point when she argues that the young brain can’t handle overstimulation of fast action and reaction. But isn’t that the same argument we’ve been making about all technology and entertainment for decades now? Everything has a trade off, and I’d argue the benefits in communications, education and collaboration of the Web are far more than the negatives, and indeed give us greater benefits than we get from TV or Guitar Hero.
    As more of our social graphs move online, via Twitter or Facebook, the more the same social pressures of the real world come to bear. Compare anonymous You-Tube comments with Twitter comments. Generally, Twitter is more kind and substantive, especially among users who Twitter under their real names. Now compare that to comments on Facebook, almost all of the comments on someone’s photo, video, status are supportive and empathetic, because the site has imitated real world relationships and with that real world pressures.
According to the passage, which of the following social networking sites has the most positive comments?
选项 A、Twitter.
B、Facebook.
C、YouTube.
D、Second Life.
答案B
解析 推理判断题。由题干定位到最后一段可知，与匿名的YouTube上的评论相比，Twitter上的评论更加善意。而后者与Facebook上的评论作比较，几乎所有对于别人的照片、视频和头像的评论都是支持性的，感同身受的，因为这个网站模仿了真实的世界，也有着真实世界里的压力。由此可知，Facebook里的评论是最积极的，故B正确。
