ESP书面文本的句法复杂度分析 ——从语体功能侧面展开的研究

为研究ESP书面文本在句法复杂度方面具有的特点以及这些句法资源所要实现的文本功能，以自建语料库为基础，借助 语体多维分析框架，对ESP和EGP两类文本做对比分析。结果显示：相较于EGP，ESP在句法复杂度和语体两方面特征明显； ESP范围内，句法复杂度对文本互动性、指称明晰性、显性劝说性和即席信息组织精密度具有显著的预示作用。研究证明不同 语域文本在句法层面体现出的差异性有利于实现各自文本的特定交际目的。

A Study on the Syntactic Complexity of ESP Written Texts from the Perspective of Textual Functions

To study the unique syntactic complexity features in the ESP written texts and the textual functions realized by those syntactic resources, An ESP corpus is built, based on which a contrastive analysis of ESP and EGP text is conducted by adopting the framework of mufti-dimensional analysis. Results show that compered with EGP,ESP text is significantly different from EGP in syntactic complexity and textual dimensional features. In ESP texts, syntactic complexity can significantly predict the degree of textual interactivity, referential explicitness, overt persuasion and the online informational elaboration. This study demonstrates that differences on syntactic levels among texts from different registers are conducive to the realization of textual functions.
