用于表达态度和介入渐变程度的级差系统是评价理论系统的重要子系统之一。我们以《呼啸山庄》为例,分析小说的级差系统中聚焦和语势这两个范畴资源,发现其中有丰富广泛的级差资源,特别是语势资源应用很多。多种手法的相互作用构成了级差资源的配置,有利于呼应小说激烈情感的主题。 One of the most important subsystems of evaluation theory system is the level difference system used to express the attitude and the degree of intervening gradual change. Taking Wuthering Heights as an example, we analyze the two categories of focus and linguistic resources in the grading system of the novel, and find that there are a wide range of level-difference resources, especially the language resources. The interaction of multiple techniques constitutes the allocation of level-difference resources, which is conducive to echoing the theme of fierce emotions in novels.
