      Unbounded Dependency

      無界依存

       

      A term used in some theories of grammar (such as generalized phrase-structure grammar) to refer to a construction in which a syntactic relation holds between two constituents such that there is no restriction on the structural distance between them (e.g. a restriction which would require that both be constituents of the same clause). In English, cleft sentences, topicalization, WH-questions and relative clauses have been proposed as examples of constructions which involve this kind of dependency; for instance, a wh-constituent may occur at the beginning of a main clause, while the construction with which it is connected may be one, two or more clauses away. In government-binding theory, unbounded dependencies are analysed in terms of movement. In GPSG, use is made of the feature slash.

       

      最近一些語法理論(如概化短語結構語法)用來指一類構式,其中兩個組構成分之間持有某種句法關系而又不受這兩個成分結構距離的限制(例如不受兩個成分都須屬同一小句的限制)。英語中有人認為分裂句、話題化句、WH-問句和關系小句都是有這類依存關系的構式的例子;例如,一個話題或話題化成分可出現在主要小句的開頭,而與其發生聯系的構式可能隔開一個、兩個或多個小句。在管轄與約束理論中,無界依存關系用移位來分析。在GPSG中,采用的是斜杠這一特征。
