This research uses the comparative study method, compares the variances between Chinese and German virtual expressions from the communicative perspective, and finds that German virtual expressions are often realized with the help of verb conjugation, whereas in Chinese, they are realized with the help of phrases or intonational auxiliaries; besides, German virtual expressions have the function of polite expression, whereas Chinese does not have the function. Besides, German virtual expressions can be recognized at the syntactic level, whereas Chinese requires the analysis from the semantic perspective. Shengyu Du and Chunyu He.
