原文呈现

AVATARS

When you are online，you can be anyone or anything.You can create your own image① and a new personality②.These digital identities③，known as avatars④，are a key⑤ part of how people use the Internet to communicate and express⑥ themselves.[1]

[1]句中的known as avatars作定语，修饰identities；how引导宾语从句，作介词of的宾语。

The first simple 2D⑦ avatars appeared in role­playing⑧ computer games in the 1980s⑨.Yet，very few people knew that future avatars would have such a wide variety of⑩ forms and uses.By the late 1990s，they had been used in web chats like instant messenger.

When people started creating⑪ 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 all⑫.[2] They could dress⑬ their avatars in fancy⑭ clothes，or they could try being someone of the opposite⑮ sex，and call themselves “Andy” instead of⑯“Anna”！ When Internet users realised⑰ that their avatars would be seen by many people，not just their friends，they started having more than one avatar: a sensible one for work；a friendly，good­looking⑱ one for meeting people；and a silly⑲ one for having fun.Avatars let you express yourself and they give you lots of room for creativity.

[2]when引导时间状语从句，第一个that引导宾语从句，作discovered的宾语；第二个that引导定语从句，修饰先行词new identities。

Of course，the avatar you choose says a lot about your personality.If your blog⑳ avatar is a picture of a cute cat，your message is “I like relaxing and having fun”．Well­known 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 nice­looking，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.

Nowadays，avatars are everywhere.In most web chats，people choose an avatar from a selection of ready­made 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.

虚拟形象

当你在线时，你可以是任何人或任何事物。你可以创造自己的形象和新的个性。这些被称为虚拟形象的数字身份是人们如何使用互联网进行交流和表达的关键部分。

20世纪80年代，角色扮演游戏中出现了第一个简单的二维虚拟形象，但是，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可爱的猫的照片，你的信息是“我喜欢放松和快乐”。著名的卡通人物或大笑的猴子表达“我是一个非常有趣的人”。大多数人创造的虚拟形象和他们的个性有相同的特征，看起来或多或少像他们，表现得像他们。然而，几乎所有的虚拟形象都高大、年轻、漂亮，人们明显地使他们的虚拟头像看上去好于实际生活中的。他们还尝试了一些事物比如不同的发型，这些事物也许很能说明他们想要看起来什么样子。

如今，虚拟形象无处不在。在大多数网络聊天中，人们从一组现成的图片中选择一个虚拟形象，或者创建自己的图片。你输入信息时也可以使用能移动或说话的虚拟形象。网络世界中的虚拟形象可以聊天、散步、飞行、认识人、购物和上课。

虚拟形象的使用也已经引起了一些担忧。一些网民开始担心自己在虚拟世界沉溺太久，以至于开始害怕在现实中与人交往。使用多个虚拟形象也有风险，因为人们可以使用虚拟形象在网上欺骗他人。然而，一些人以更积极的目光看待虚拟形象。他们期待着有朝一日，自己的虚拟形象会像真人一样去环游更广阔、更精彩的虚拟世界。
