As I noticed yesterday, the first record sent into space is also a monument--and that comes from the 1950's. And in the same way, each nation has something so important for it that even from a recent point of view it could be proclaimed as a monument and could be put on the list of UNESCO monuments.
所以現在，人類第一次向太空發射衛星的紀錄已經被列為「古蹟」，而這只有四十多年歷史；同樣的，每一個國家都有一些對它自己非常重要的地方，從新的眼光來看，它就應該被列為紀念物而加以保存。
