What is linguistics? 什么是语言学?请帮忙给出正确答案和分析 谢谢！

正确答案：Linguistics is the scientific study of language．It studies not just one language of any one community(tribe or society)but the language of all human beings．A linguistthough not having to know and use a large number of languagesought to have a wide experience of different types of language．His task is not to learn to use any one particular languagebut to investigate how each language is constructed．He is also concerned with how a language varies from dialect to dialectfrom class to classhow it changes from century to centuryhow children acquire their mother tongueand perhaps how a person learns or should learn a foreign language．In shortlinguistics studies the general principles whereupon all human languages are constructed and operate as systems of communication in their societies or communities 语言学是对语言进行的科学性研究。语言学不仅研究某一社会(部落或社团)的某种语言而且研究人类语言这个整体。尽管一个语言学家不必懂得且会使用大量的语言但他必须对各种各样的语言有所了解。语言学家的任务不是学习怎样使用某一特定语言而是考察和研究每一种语言的结构如何。他也会考察和研究语言的方言差异如何阶级差异如何各阶段变化如何儿童是如何习得母语的以及个人如何或应怎样学习外语等问题。总而言之语言学研究所有作为社会或社团交流系统的人类语言构造和操作的总原则及一般规律。
