大王。放暑假了，来自科幻世界的仙霞姐姐为爱好科技的孩子们创办了一个“AA 欢乐营”，让孩子们在那里度过了一个有趣、欢乐的假期。在AA欢乐营中，孩子们懂得了互相学习、团结友爱、自强自立、认真负责等道理，在那里，他们遇到了一个又一个与自然界息息相关的问题：如恒温动物和变温动物的区别；数学中勾股定律的历史、概念；化学中水是由什么物质组成的；物理中光点的产生和原理等等。围绕这些自然界的课题，孩子们都展开了激烈的辩论。暑假很快就要结束了，仙霞姐姐为孩子们设计了一次考试，孩子们通过自己的智慧和勇气，解开了一道道难题，结束了考试，取得了优秀的成绩。仙霞姐姐希望孩子们今后继续努力学习，用自身学到的知识来为祖国现代化科学做出贡献。The value of this Token must be random and unpredictable.
