摘要：As an essential element of discourse, coherence has been the focus of study for several decades. Previous researches mainly view discourse coherence as a static product and explore it on linguistic level. However, it is also a dynamic process and can be achieved by the cooperation made by the discourse producer and receiver based on their mutual understanding. It involves both linguistic and non-linguistic factors. In this article, the author reviews previous researches on discourse coherence and presents the nature of discourse coherence from cognitive perspective, aiming at giving an insight into discourse comprehension and teaching.
