人的语言与动物表达行为之间具有密切的关联:动物拥有了除人类有声语言之外所有表达形式,也几乎可以表达人类所要表达的全部内容,差距只是量上的差距,在表达方式上,动物已部分采用了符号表达,虽然人类对符号表达的使用上远远超过动物,但这并不构成人与动物本质上的区别。 There is a close relationship between human language and animal expression: animals have all the forms of expression except for human vocal language, and almost all the human beings can express. The difference is only the difference in quantity. In the way of expression, The animal has partly adopted the symbolic expression. Although humans use far more symbols than the animals, this does not constitute a fundamental difference between humans and animals.
