The paper will explore in two areas of the tenor of interpersonal function and transitivity of experiential meta-function. The purpose of the paper tries to verify unconcerned relationship among people in it and the writer's writing style-iceberg rule and the operative theory of SFL on the analysis of literary text.展开更多
