This document discusses applying cognitive linguistics to teaching Chinese as a foreign language, using the words "白" and "把" as case studies. It outlines how cognitive linguistics views categories as complex networks rather than rigid definitions, and how this perspective can help Chinese learners understand polysemy and metaphorical extensions. The document presents cognitive maps of the categories for "白" and "把" to illustrate their complex, interconnected meanings. A pilot study was conducted using learning activities at different stages to evaluate this cognitive linguistics approach. The presenters conclude that this framework can enhance learning Chinese grammar by making the relationships between forms and meanings more apparent.
