The surface form of arguments in natural discourse, theoretically freely chosen, is by no means arbitrary. Clear tendencies emerge when analyzing stretches of discourse. One such pattern concerns the different proportions of lexically realized arguments in A, as opposed to S and P, and has been explained by Du Bois through a set of underlying principles. The pattern has more recently been suggested to be an epiphenomenal effect of animacy. In this paper, I analyze a corpus of Mapudungun narratives and investigate the form and information status of 4,218 references. The results show S between A and P in its lexicality, and a discord with constraints constituting PAS. There is also an unexpectedly high proportion of lexical human S arguments, independent of information status. Not only do these findings contribute to the growing body of evidence suggesting that PAS is flawed and that animacy should not be neglected, they also suggest that animacy alone does not explain all patterns. In addition, they promote an independent treatment of information status and formal expression in this kind of corpus study.

马普敦贡语叙事中首选论点结构的考察

自然话语中论证的表面形式，理论上是自由选择的，绝不是任意的。在分析一段话时会出现明显的倾向。一个这样的模式涉及 A 中词汇实现的论点的不同比例，而不是 S 和 P，杜波依斯已经通过一组基本原则进行了解释。这种模式最近被认为是生命力的附带现象。在本文中，我分析了一个 Mapudungun 叙事语料库，并调查了 4,218 篇参考文献的形式和信息状态。结果表明，S 的词汇量介于 A 和 P 之间，并且与构成 PAS 的约束不一致。还有一个意外的高比例的词汇人类 S 参数，独立于信息状态。这些发现不仅有助于越来越多的证据表明 PAS 存在缺陷并且不应忽视生命力，它们还表明生命力本身并不能解释所有模式。此外，在这种语料库研究中，它们促进了对信息状态和形式表达的独立处理。
