想象什么？具体点。
时间过得真快呀！现在已经到了二十三世纪，而我已经是一个小小的发明家了。我发明了一种智能书包，这个书包的功能可多了。
你走在路上，如果觉得书包很沉，只要按下书包上蓝色的按钮，书包就会自动减负，因为书包里安装有减压设备，把重力减到四分之一。

如果你的作业做完了，只要你一按绿色的按钮，书包就会长出一只手自动帮你整理书本。因为书包里装了最新的智能芯片，它会帮你把书本，作业，文具分类，帮它们找着合适的“家”。
这么高级的书包，你担心会掉了或者被盗吗？不用担心，按下红色按纽，就不怕被盗了，因为智能书包装了自动识别装置，它会自动记录下跟你接触过的人的脸，倘若有陌生人向它伸出手，它马上就会“嘀嘀嘀”地报警。
怎么样，我发明的书包酷吧？我还会继续研究，未来的书包一定会更好！
