【正确答案】Linguistics is usually defined as the science of language, or, alternatively, as the scientific study of language. While language teaching is concerned with how language can be taught more effectively. Therefore, the relationship between linguistics and language teaching is quite obvious. Language teaching is part of applied linguistics and applied linguistics is part or a branch of linguistics.
Some knowledge of linguistics will not only help language teachers to better understand the nature of language, but also help them better understand how to teach language. Theoretical views of language explicitly or implicitly inform the approaches and methods adopted in language teaching. In fact, linguistics, as the science of language, should be of fundamental importance for teachers of language. Language teachers should be concerned with how to teach language effectively, but not all of them know how. In this sense, linguistics is needed in order for language teachers to teach language effectively. They need to know at least how the language they teach works.

【答案解析】[解析] 本题实际上考查的是语言学与语言教学之间的关系，与2008年的试卷中第12题考查的内容几乎一模一样，只是题目的表述不同而已。可以参考胡壮麟《语言学教程》(第三版)266-267页。
