英语翻译
Many things about language are a mystery and will remain so.However,we now do know something about it.First,we know that all human beings have a language of some sort.No human race anywhere on earth is so backward that it has no language of its own at all.Second ,there is no such thing as a primitive language.There are many people whose cultures are undeveloped but the languages they speak are by no means primitive.In all the languages existing in the world today,there are complexities that must have been developed for years.Third,we know that all languages are perfectly adequate.Each is a perfect means of expressing its culture.And finally,we know that language changes over time,which is natural and normal if a language is to survive.The language which remains unchanged is nothing but dead.

很多关于语言的事情是个谜并且仍将如此.但是,我们现在确实知道了一些它的东西.首先,我们知道所有人类都有某种语言.地球上任何地方没有哪个人种是根本没有自己语言的.其次,没有类似原始的语言.有很多文化未发展但是所说的语言绝不是原始的了人群.全世界现存的语言中,有很多一定已经发展多年变得复杂.第三,我们知道所有的语言都是十分富足的.每种都是表达自身文化的完美方式.最后,我们知道语言随时间改变,语言要传承下来这就显得很平常了.没有变化的语言死路一条.
