主宾易位句的题元特征层级分析

Studies on Hierarchy of θ-features in Flip-flop Sentences

主宾易位句是违反题元等级的论元配置结构,在Larson题元特征层级(Hierarchy ofθ-Features)理论框架下,通过可解释、不可解释的题元特征与取定值、未取定值题元特征的协约(agree)操作,对正则主宾语、非正则主宾语的主宾易位句的句法衍推过程进行了统一化处理,研究发现遵守题元等级的原式依次进行题元特征协约操作、违反题元等级的变换式需要纯粹的轻动词或语义轻动词的协助来完成题元特征的协约进而实现主宾易位。

Flip-flop sentences are the argument configuration structures that violate the thematic hierarchy.Based on the prototype concept of proto-agent and proto-theme,this paper provides a unified elaboration on the syntactic derivation of flip-flop sentences comprised of canonical and non-canonical subjects and objects in the framework of hierarchy ofθ-features proposed by Larson,by conducting agreement between instances of features F according to whether they are interpretable,valued or neither.The study shows that the original structure with thematic order of arguments conduct agreement of thematic feature in turn while the transformed one with contra thematic order of arguments needs to resort to pure light verb or semantic light verb to achieve the subject-object dislocation by agreement.
