Basis and boundaries of unaccusativity: the role of voice morphology and auxiliary selection

动词的意义如何与这些动词所处的句法结构相关联是语言学理论中一个相当重要的问题，这一领域的研究主要集中在言语/素质交替上，即言语论点表达的交替。此外，句法和形态模式之间的联系，特别是在反映结构变化的程度上，对我们理解语法成分之间的分工变得越来越重要。该项目研究了两种现象，这两种现象符合语法-形态联系的代表，并且对论点结构和/或口头变化的特性很敏感。它们是：(i)交替动词的不及物对应物（反谓语）上的特殊（语音）形态的存在，通常被认为是非宾格。（ii）完成形式的助动词选择（HAVE和BE），标准地将不及物动词分为两组，非负格（选择HAVE）和非宾格（选择BE）。[…]

How the meanings of the verbs relate to the syntactic structures in which these verbs appear is a question of considerable importance for linguistic theory, and the research in this area focuses on verbal/diathesis alternations, i.e. alternations in the expression of verbal arguments. In addition, the connections between syntax and morphological patterns, especially to the extent that these reflect structural alternations, are becoming increasingly important for our understanding of the division of labour among grammatical components. This project investigates two phenomena that qualify as representatives of the syntax-morphology connection and are sensitive to properties of argument structure and/or verbal alternations. These are: (i) the presence of special (voice) morphology on intransitive counterparts of alternating verbs (anticausatives), standardly taken to be unaccusatives. (ii) Auxiliary selection in Perfect formation (HAVE vs. BE), standardly splitting intransitive verbs into two groups, unergative (select HAVE) vs. unaccusatives (select BE). [...]
