实体性语用特征的性质

On Nature of Pragmatic Features of the Entity

语用特征作为一种非线性句法特征,与句法成分不同,可以作用于全句与某种句法成分,需要采用移位、添加标记、重叠、删除等句法手段得到形式上的体现,从而影响句子的生成机制。非线性特征根据附着成分的不同可以分为两类:实体性语用特征与全句性语用特征。话题特征和焦点特征附着于具体的句法成分,可以影响句子的生成机制,但在性质上与作用于全句的语用特征有本质的区别。

Pragmatic features,as a kind of nonlinear syntactic features,are different from syntactic components and they can be used on the whole sentence and certain syntactic constituents as well. It can be performed by shift,adding tags,overlapping,deleting,thus affecting the formation mechanism of a sentence. The nonlinear characteristics can be divided into two categories according to different attachments,the entity of the whole sentence and the pragmatic features of pragmatic features. The characteristics of topic and focus features are attached to specific syntactic constituents,which may affect the generative mechanism of a sentence. But they are critically different from pragmatic features in nature.
