3、y.These digital identities，known as avatars，are a key part of how people use the Internet to communicate and express themselves.The first simple 2D avatars appeared in role-playing computer games in the 1980s.Yet,very few people knew that future avatars would have such a wide variety of forms and us

4、es.By the late 1990s，they had been used in web chats like instant messenger.课文译文课文译文当你在网上时，你可以是任何人或任何事物。你可以创建你自己的形象和一个新的个性。这些数字身份被称为虚拟形象，是人们使用互联网来交流和表达自己的关键之处。第一个简单的2D虚拟形象出现在20世纪80年代的角色扮演类电脑游戏中。但是，当时几乎没有人想到，虚拟形象在未来居然有如此多样的形式和如此广泛的应用。到了20世纪90年代后期，它们已经被应用在网络聊天，如即时通信中。当人们开始创造他们自己的虚拟形象时，他们发现他们将有能力创造新的身份

5、，而这些身份无论是外貌还是行为完全不像他们真实的自己。他们可以给虚拟形象穿上奇装异服，或者他们可以尝试成为异性，称自己为“安迪”而不是“安娜”！当互联网用户意识到他们的头像会被很多人看到，而不仅仅是朋友，他们开始拥有不止一个头像：明智的一个用于工作，长得友好、好看的一个用来与人会面，长得傻傻的用来找乐子。虚拟形象让你表达自己，给你很大的创造空间。当然，你选择的头像很能说明你的个性。如果你的博客头像是一张可爱猫咪的照片，你释放的信息是“我喜欢放松和快乐”。而著名的卡通人物或大笑的猴子表达“我是一个很有趣的人”。大多数人创造的头像都与他们的个性特征相似，或多或少相似，行为也和他们相似。然而，几乎所

6、有的头像都是高个子，年轻，漂亮的，所以人们显然会让他们的头像比真实生活中的他们更好看。他们也会尝试像不同的发型这样的事情，这很可能会体现他们理想中的样子。如今，虚拟形象无处不在，在大多数网络聊天中，人们从现成的图像中选择一个虚拟形象，或者创造自己的形象。当你输入信息时，你也可以使用可以移动和说话的虚拟形象。网络世界中的虚拟形象可以说话、走路、飞来飞去、与人会面、购物和上课。虚拟形象的使用也引起了一些担忧。一些用户担心他们在虚拟世界中花费了太多的时间，以至于他们害怕与现实世界中的人见面。数个虚拟形象的使用也可能是一种风险，因为人们可以使用虚拟形象在网上欺骗他人。然而，其他用户用更积极的眼光看待虚
