Description of a Process Language, like any other aspect of life and human behavior, changes from one generation to the next. As children we learn our first or native language from our parents. It is then modified through association with playmates, who learned their language from their elders. This learning process is heightened and extended in school. In adulthood our language attains relative stability. It reflects our education, our occupation, our personal interests and contacts—in short, our total environment. By this time, however, we are already conveying the language to our children, and the process begins a new cycle. The history of a language is an account of what has happened to it in the course of its continuous transmission from one generation to another. 本段运用一般现在时、以时间顺序叙述了人类的语言习得过程
