投射原则与超常题元结构

计算系统中,形态规则会抑制谓词部分论旨角色(常为“致使”或“施事”)的正常释放,造成派生谓词论旨角色分派的数目较少,但并不违背投射规则,不会改变论旨角色的特性,只会造成题元结构中的减元;题元在句法规则的驱动下被迫前移到功能词类T的标识语位置进行格的特征核查;如果题元并不发生句法移动,填充词的插入还会导致题元增元(准题元);最终造成谓词的超常题元结构。

The projection principle and abnormal argument structures

Morphological rules may suppress part theta roles (normally Causative or Agentive), causing a decrease in the number of the theta role (s) assigned, hence also a decrease in the number of argument(s), without violating the PP though, nor altering the idiosyncratic properties of the base-generated predicate. Accordingly, the theta-marked argument has to move upwardly to [Spec, TP] to check case feature, motivated by the morphological necessity of T; or else an insertion of the expletives it is obligatory, causing a case of argument augmentation ( a quasi-argument) . These morphological rules and syntactic operations result in an abnormal argument structure of the predicate generally.
