一课文《叫三声夸克》的开头是这样的: 有一种礼品盒,看上去只是一个盒子,不知道里面是空的,还是装了什么东西。打开来看看,里面仍然是一个盒子。好奇心驱使,再打开这个盒子,里面又是一个盒子……总之,盒子里装盒子,不知道最里面的盒子里面到底是什么。
The beginning of a text called “Triple Quark” looks like this: There is a gift box that looks like a box without knowing what’s empty or what’s in it. Open to see, there is still a box. Curiosity drove, and then opened the box, which is another box ... ... In short, boxed box, do not know what is inside the box inside.
