摘要
In 1976,Halliday and Hassan put forward the concept of cohesion and coherence theory for the first time in their book English Cohesion and discussed five types of cohesion:reference,substitution,omission,conjunction and lexical cohesion.Some scholars enriched and expanded cohesion and coherence from the perspective of cohesion conditions,phonology,structural relations at the level of meaning and discourse.Predecessors pay much attention to the theoretical discussion,while from the perspective of the theoretical application,the cohesion and coherence theory is used for analyzing the advanced college English textbook to provide the guidance for teachers and students in teaching and learning-teachers can judge and adopt appropriate teaching methods according to the cohesion and coherence theory;Students can understand cohesion and coherence in the text as well as the influencing factors,and adequately use the cohesion and coherence mechanism in listening,speaking,reading and writing.
