Abstract: The Accessibility Hierarchy Hypothesis helps explain the influence of the grammatical roles of antecedents on anaphora use, but the influence of the grammatical configuration of antecedents and anaphora on the choice of anaphora types has rarely been discussed. Based on 40 narrative texts with the same topic, this paper examines the characteristics of grammatical roles and forms of anaphora in written and spoken contexts, and specifically explores the differences in the choice of anaphoric types under the four grammatical configurations of antecedents and anaphora(subject-subject, subject-object, object-subject, object-object). It also discusses genre differences in the grammatical roles and types of anaphora, and in the parallel effect of antecedent-anaphora configuration.
