列宁说过:“语言是人类最重要的交际工具。”斯大林说过:“有声语言在人类历史上是帮助人们脱出动物界、结成社会,发展自己的思维,组织社会生产,同自然力量作胜利的斗争并取得我们今天的进步的力量之一。”其中特别值得注意的词语是“社会”、“交际”、“生产”、“进步”和“力量”,说明了语言在人类社会的文明进步中的重要作用。语言是社会中每一个人所需要的。什么样的社会就需要什么样的语言。不难想象,原始人类的语言决没有现代语言这样繁复而有多样的讲求。说到近代,也是随社会发展而变化着的。就以北京话来说,我是北京人,回忆起六七十年前我的儿童时期日常生活中的词语,有许多今天已逐渐消灭,而代之以新词语。对劳动人民轻蔑、侮辱的称呼听不到了,神鬼迷信的话语听不到了,听到的是工人、师傅、表演艺术家等尊重 Lenin said: “Language is the most important human communication tool.” Stalin said: "Sound language in human history is to help people fall out of the animal kingdom, form a society, develop their own thinking, organize social production, and work with natural forces. The struggle for victory is one of the strengths of our progress today.” The words that are particularly noteworthy are “society,” “communicative,” “production,” “progress,” and “power,” illustrating the language’s civilization in human society. The important role of progress. Language is what everybody in society needs. What kind of language is needed for what kind of society? It is not difficult to imagine that the language of primitive humanity is by no means as complicated and diverse as modern languages. When it comes to modern times, it also changes with the development of society. In Beijing dialect, I am a Beijinger. I recall the words in my daily life during the childhood of six or seventy years ago. Many of them have gradually disappeared today and replaced with new words. The scorn and insults of the working people cannot be heard. The superstitious words cannot be heard. They hear the respect of workers, masters, performing artists, etc.
