Research on the Construction of Value Evaluation Model of Pragmatic Function of Spoken English Discourse Markers Under the Perspective of Smoking Cessation Discourse

Abstract

In view of the needs of the use of spoken English discourse markers in different situations under cross-cultural communication, it is necessary to standardize the language use of communicators and give full play to the pragmatic value of spoken English discourse markers. By establishing the pragmatic function evaluation model of spoken English discourse markers in the context of smoking cessation and tobacco control from the perspective of smoking cessation discourse, English communicative conversation in the context of smoking cessation and tobacco control is studied in this paper. Based on the analytic hierarchy process (AHP), and starting from four layers including the target layer, criterion layer, index layer and scheme layer, this paper designs an evaluation model of pragmatic functional value of spoken English discourse markers from the perspective of smoking cessation discourse through hierarchy theory model construction, judgment matrix construction, hierarchical single ranking and consistency test, hierarchical total ranking and consistency test. The model is used in the context of communication, language training and language assessment. The model is suitable for simulating communicative behavior, language ability training and language ability assessment in smoking cessation and tobacco control scenarios. It can improve the accuracy of the use of discourse markers, facilitate the reasonable choice of discourse markers in special communication scenarios, ensure the efficiency of English communication, and highlight the unique value of discourse markers in different communication scenarios.
