Summary
Ⅱ 语法填空 （根据课文内容和语法规则完成短文）
　　The digital identities，1　　　　（know） as avatars，are a key part of how people use the Internet to communicate and express 2　 　　　（they）. The first simple 2D avatars 3_________　　　　（appear） in role-playing computer games in the 1980s. Yet，very few people knew that future avatars would have such a wide 4　　　　（vary）of forms and uses. People had the power 5__________（create）new identities that didn’t look or act like their real selves at all. One person could have several avatars.
　　The avatar you choose says a lot about your personality. However，nearly all avatars are tall，young and nice-looking，so people 6　 　　　（obvious） make their avatars look better than they do in real life. Nowadays，avatars are everywhere. The avatars in online worlds can talk，walk and fly around，meet people，go shopping and attend classes.
　　Of course，the wide use of avatars has led 7　　　a few concerns. Some users are concerned that they are spending 8　　　　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 9　　　　their avatar will act like a real person and travel around bigger，more 10 　　　　（excite）virtual worlds.
