近二百年以来，外语教学模式的变迁伴随着西方语言学理论研究不断的深入。本文试图从科学的西方语言学史学角度分析和研究外语教学法历史演变的进程，从新视角，多层次论述19世纪初以来西方语言学流派对外语教学模式的影响和作用以及语言学家们通过外语教学实践的观察和思考归纳语言学理论，推导立论，创新西方语言学理论的历程。

For almost 200 years, the prevalent modes of foreign language teaching (FLT) have undergone gradual development and changes, alongside the research on western linguistics. This thesis studies the changes of the methodology of FLT in light of the history of western linguistics, and observes the impact of different schools of western linguistics on the mode of FLT since the beginning of the 19th century. It also analyzes the course in which linguists have induced linguistic theories via observation and meditation on FLT practices.
