根据汉语提示完成下面短文，一横线只填一个词：
模块1由五个单元组成。第一单元说的是那座装饰着黄金和珠宝的令人惊奇的琥珀屋。二战期间，当俄国和德国交战时，它莫名其妙地失踪了。琥珀屋到底发生了什么事到现在还是个谜。
第二单元是关于奥运会的。在古代，奥运会只在希腊每四年举办一次，其他国家没有参加，奴隶和女性也不能参加。可现代奥运会就不同了。不仅允许妇女参加，而且妇女在许多项目还起着很重要的作用。
我最感兴趣的是第三单元。说的是电脑。到二十世纪四十年代，电脑还跟一个房间一样大。随着时间的流逝，他被制作地越来越小了。后来连接网络后，电脑就能够通过万维网和其他人分享知识了。为了给人类提供高质量的生活，人们投身于创设一个更好的系统。
第四单元说到了野生动植物的保护，有的地方非常重视，而有的地方动植物在不断灭绝，比如说恐龙，大约六千五百万年前就突然消失了，没人确切地知道在这么短的时间内恐龙为什么又是怎么从地球上消失的。
至于第五单元，说的是音乐和乐队。我们都喜欢音乐，甚至梦想着有朝一日能够在音乐会上面对成千上万的人表演，但是不是每个人都能唱好。即使是一支非常受欢迎的乐队，也可能会遇到解体的时候。
