中文摘要：

本文利用依存句法标注的真实语料研究有声媒体类词类句法功能的语体差别。结果显示，各类词在书面语中作定语的倾向大于口语；在口语中名词有很强的充当宾语的能力；代词有很强的充当主语的能力；动词和形容词作谓语的能力在口语中都强于书面语。在口语中量词与代词结合的能力远远强于书面语。

英文摘要：

The paper aims to statistically investigate the style-related differences in syntactic functions of word classes based on syntactically annotated corpora. The results show that all word classes in the written Chinese are more likely to be used as the attribute than in colloquial Chinese. In addition, in colloquial Chinese, nouns have a stronger tendency to function as the object, and pronouns have a stronger tendency to be the subject. Finally, in colloquial Chinese, verbs and ad- jectives are more often used as the predicate, and pronouns far more frequently collocate with quanti- tiers.
