Language reflects the path of social development, for every major change to the society in the history of China has brought a myriad of new terms into existence. Language, a social phenomenon evolves with the community. Lexis is the most active element of languages, because social changes, scientific and technology advances, new thinking and fresh ideas are quickly embodied in the word-stock. Most prominently, there have emerged huge quantities of coinages, new meanings and usages. As recently as last century, to say nothing of the distant past, neologisms peaked around May 4th Movement in 1919, in the infancy of the People's Republic of China, and after reform and opening up to the outside world respectively. In recent years, for example, with the emergence of a new thing—the web, a large number of web-related new words found their way into our life, such as the internet, email, dotcoms, online schools, websites, web pages, cybercrime and such like things that are the best instances of the co-evolution of language and society. At the same time, language is a mirror of the society. If it undergoes great changes, not a tongue can possibly remain unaffected or unchanged. Language can also help reinforce some ideas, even some kind of ideology, so whether one is conservative or revolutionary, he uses his language in a specific way.
