语言是开放性的系统,它随着社会的发展而发展,语言诸要素中词汇的发展是最快的,对社会变化的反映也是最活跃最敏感的。随着人们知识面的扩大,知识结构的变化,一些专业词汇也渐渐进入人们的日常生活,被人们所了解和应用。达尔文在《物种起源》第二章《在自然状况下的变异》中写 Language is an open system. It develops with the development of society. The development of vocabulary among the various elements of language is the fastest, and the reflection of social changes is also the most active and sensitive. With the expansion of people’s knowledge, changes in the structure of knowledge, some professional vocabulary gradually into people’s daily lives, people understand and apply. Darwin wrote in chapter two of “The Origin of Species,” “Variation Under Natural Conditions.”
