In this paper, the author applies Jef Verschueren’s Pragmatics as a Theory of Linguistic Adaptation as the theoretical basement. And the generation of code-switching is discussed under the guidance of Yu Guodong’s Adaptation Model as well. Conclusions can be drawn as:teacher’s English/Chinese codeswitching is an adaptation to linguistic reality, social conventions and teacher’s psychological intentions, the first two being considered as passive switching and the last being active switching. Teacher’s codeswitching as understanding-facilitating strategy forms the most important factor that triggers teacher’s English/Chinese codeswitching.
