Abstract: Plenty of studies have revealed that there is a clear evidence for a link between ToM and language, but what exactly they are is still left unknown. The latest researches about their relations have been introduced and two dominant views are presented in this paper: (1) There is a certain causal link between theory-of-mind and language, of which 2 points are included, one is the causal link from language to theory-of-mind, language plays a fundamental role in ToM development, the other is the causal link from theory-of-mind to language ability. (2) Theory-of-mind and language both depend on some other factors, such as executive function and living environment, but how do those factors work needs further discussion. The future trends and new approaches are discussed, including research on across-culture, comparative study in various language ability, life-span research of their relations etc

Key words: theory-of-mind, language, false belief
