You can create your own image and a new personality．  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 uses．By the late 1990s，they had been used in web chats like instant messenger． 你选择的虚拟形象说明了很多关于你的信息。这篇文章将帮助你更好地理解你对虚拟形象的选择。当你在线时，你可以是任何人或任何事物。你可以创造你自己的头像和新的个性， 这些被称为虚拟形象的数字身份是人们使用互联网进行交流和表达的关键部分。 20世纪80年代，第一个简单的二维虚拟形象出现在电脑游戏中的角色扮演。然而，很少有人知道未来的虚拟形象会有如此广泛的形式和用途。到了90年代末，它们已经 用于即时通讯等网络聊天。 片段3：When people started creating their own avatars，they discovered that they were going to have the power to create new identities  that did not look or act like their real selves at all．They could dress their avatars in fancy clothes，or they could try being someone of the opposite sex，and call themselves "Andy" instead of "Anna"! When Internet users realised that their avatars would be seen by many people，not justtheir friends，they started having more than one avatar：a sensible  one for work；a friendly，good-looking one for meeting people；and a silly one for having fun．Avatars let you express yourself and they give you lots of room for creativity.  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出一点也不像真实自我的新身份。他们可以给他们的虚拟形象穿上花哨的衣服，或者他们可以试着成为一个异性，并称自己为“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，而不仅仅是他们的朋友，他们开始拥有不止一个头像：一个对工作来说很明智的头像；一个友好、漂亮的头像。 一个是用来认识人的，另一个是用来找乐子的。虚拟形象让你表达自己，给你很大的创造力空间。 片段4：Of course，the avatar you choose says a lot about your personality．If your blog avatar is a picture of a cute cat，your message is "I like relaxing and having fun"．Well-known cartoon characters or laughing monkeys say "I'm a really funny person"． Most people create avatars that have similar features to their personalities and that look more or less like them and act like them．However，nearly all avatars are tall，young and nice-looking，so people obviously make their avatars look better than they do in real life． They also experiment with things like different hairstyles — which says a lot，perhaps，about what they want to look like． 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只可爱的猫的照片，你的信息是“我喜欢放松和享受乐趣”。著名的卡通人物或大笑的猴子会说“我是一个非常有趣的人”。大多数人创造的头像与他们的个性特征和外观相似，几乎所有的虚拟形象都是高个子，年轻漂亮的，所以人们显然会让他们的虚拟形象看起来比现实生活中的更好。 他们也会尝试不同的发型，这也许能说明他们想要什么样的发型。 片段5&6：Nowadays，avatars are everywhere．In most web chats，people choose an avatar from a selection of ready-made images，or create their own images． You can also use avatars that move around and talk when you type in your message．The avatars in online worlds can talk，walk and fly around，meet people，go shopping and attend classes． The use of avatars has also caused a few concerns．Some users worry that they are spending so much time in virtual  worlds that they are becoming afraid of meeting people in the real world．The use of several avatars can also be a risk，as people can use avatars to cheat  others online．However，other users view  avatars in a more positive light． They look forward to a time when their avatar will act like a real person and travel around bigger，more exciting virtual worlds．  如今，虚拟人物无处不在。在大多数网络聊天中，人们都会从以下几类内容中选择一个头像 现成的图像，或者创建他们自己的图像。你也可以使用移动和交谈的虚拟形象。当你输入你的信息时，网络世界里的虚拟形象可以聊天，走动，飞行，与人见面，去购物和上课。 头像的使用也引起了一些担忧，一些用户担心他们花了太多钱。在虚拟世界中，他们开始害怕在现实世界中遇到人。头像也是一种风险，因为人们可以利用头像在网上欺骗他人。从更积极的角度来看，他们期待有一天他们的虚拟形象能像真人一样行动在更大、更令人兴奋的虚拟世界里旅行。 白板画思维导图 集体梳理/抢答 Module Summary 本节课特别表扬学员的有（守纪）： 本节课表现积极学员有： 本节课最优秀小组： 桌椅摆整齐！垃圾请带走！ $$
