||1:Many of the universals that hold up best are negative.||2:There are many sensible things languages could do, but don’t.||3:Notably, their grammars do not make use of “continuous” features, such as the length of vowels.||4:For instance, a past-tense verb could be pronounced for a longer time to indicate how long ago the action occurred—perfectly logical, but no language does this.||5:Syntax uses discrete units, not continuous ones.||6:Whether this is proof of universality is a matter of opinion.

||1:许多最能站得住脚的普遍性都是负面的。||2:语言可以做很多看起来合理的事情，但是没有做。||3:值得注意的是，他们的语法没有使用“连续的”特征，比如元音的长度。||4:例如，过去时态动词可以发音更长的时间来表示动作发生的时间——完全符合逻辑，但是没有语言能做到这一点。||5:语法使用离散单元，而不是连续单元。||6:这是否证明普遍性是一个意见问题。
