Different people have their own opinions. Some people, especially parents and teachers, worry that teenagers spend too much time on playing games so that they ignore their studies. Besides, they are always in virtual worlds, as a result, they may be afraid to meet friends in the real world. However, others view playing computer games in a more positive light. They believe that playing computer games probably makes teenagers' minds sharper and quicker. In addition, positive roles in the games can shape children's character. 第Ⅱ卷　语篇综合训练 完形填空 If someone said they'd pay you $1,800 to stay off social media for six years, would you do it? Could you?
