把这一句，留给此刻的你

In fact, from then on scholars engaged in a kind of game of comparing different Indo-European languages with one another, and eventually they could not fail to wonder what exactly these connections showed, and how they should be interpreted in concrete terms.

事实上，从那时起，学者们就开始玩一种游戏，把印欧语系的不同语言进行比较，最后他们不禁想知道这些联系到底说明了什么，以及应该如何用具体的术语来解释它们。
