© 2010 ACADEMY PUBLISHER Lexical Cohesion in Oral English

Abstract—Based on Halliday’s cohesion theory, this study intends to explore the relationship between lexical cohesion and oral English quality. The author makes comparisons between High Quality Discourses (HQDs) and Low Quality Discourses (LQDs) from the perspective of lexical cohesion. Quantitative and qualitative analyses are used to study the different distribution and failures of cohesive devices in these two groups of discourses.
