18、hips. 译文参考 互联网损害友谊 虽然互联网可以拉近人们之间的距离，但也会损害友谊。 首先，网上聊天并不能取代面对面的接触，虚拟形象真的无法取代现实生活 中的微笑或拥抱。据育儿专家丹尼斯 丹尼尔斯说，通过屏幕进行交流，让孩子 们更难集中精力或对他人表示友好。正如我们所知，重要的社交技能是通过与他 人的直接接触而形成的。正是这些技能使我们能够发展终生的友谊。 其次， 互联网会使人们变得以自我为中心， 只关注自己， 不关注其他人和事。 例如，一些人不再和朋友进行真正的交谈了，他们只关心自己网上的人气我 得了多少个“赞”？我有多少追随者？尽管我们知道“赞”或追随者的数量 无法与拥有长期而有益的友谊相比。此外，在社交媒体上发布的很多内容都是浅 薄或琐碎的。关于有趣的猫形象的帖子不一定有助于建立有意义的关系。 第三，网络关系可能不是它们看起来的那样。友谊是建立在信任之上的，但 是在线交流时， 你绝不可能百分之百地确定和你聊天的人有没有诚实地告诉你他 们是谁。 因此， 对于那些容易受到影响或过于信任的人来说， 上网可能特别危险。 在我看来，朋友们应该更多地关注面对面的交流，更少地关注在线交流。这 是保持健康关系的最好方法。
