语码转换是两种语言的变换使用,即说话者从使用一种语言或方言转换到使用另一种语言或方言。说话者通过语码转换可以达到许多目的。本文通过对国际汉语教师在对外汉语教学课堂中的语码转换现象的分析、观察,研究了国际汉语教师语码转换现象的出现原因及其转换模式和功能类型。 Code-switching is the conversion of two languages, that is, the speaker changes from using one language or dialect to using another language or dialect. The speaker can achieve many purposes through code-switching. In this paper, by analyzing the phenomenon of code-switching among international Chinese teachers in teaching Chinese as a foreign language, we observe and study the reasons for the phenomenon of code-switching among international Chinese teachers and their conversion patterns and types of functions.
