22、代后期，它们被应用于网络聊天，如实时通信中。 当人们开始创造自己的虚拟形象时，他们发现他们能够创造一个全新的自 己，这个“全新的自己”和他们真实的外表或行为完全不同。他们可以给自己的 虚拟形象穿上奇装异服，或者他们试着成为一个异性，称呼自己为“安迪”而不 是“安娜” ！当许多网民也意识到，自己的虚拟形象不仅仅朋友可见，更多其他 人也可以看到时，他们开始拥有不止一个虚拟形象：一个用于工作的明智的虚拟 形象；一个结交人的友好、好看的虚拟形象；一个搞笑的愚蠢的虚拟形象。虚拟 形象能够让你更好地表达自己，同时还可以给你更多的创造空间。 当然，你选择的虚拟形象很能体现你的个性。如果你的博客虚拟形象是一只
