This dissertation first made a comprehensive survey of the theories of style and the theoretical models of stylistic analysis. Then it put forward the argument that systemic functional stylistics is the most influential of modern stylistics.
However, systemic functional stylistics also has its own theoretical inadequacy. The main body of the dissertation is divided into three parts. Each part examines one component of the theoretical model of systemic functional stylistics, i.e., the ideational, the interpersonal, and the textual. In the process of examination, the dissertation made some improvements to the model of systemic functional stylistics.
