论元位置的增容

论元一般指的是谓词联系的实体 (名物性成分 ) ,论元位置体现在句法结构上只有三个 ,主语、直接宾语和间接宾语。事实上 ,谓词的语义决定了论元的数目、论元的语义角色和分布位置 ,进而在句子结构中体现出来。在句子中 ,有些状语和补语位置也可以看作论元位置 ,只要该位置上的成分是谓词语义的强制性成分 ,那么 ,该成分也就是谓词的论元 ,它在句法结构中的位置就是论元位置。论元位置由原先的三个增容为现在的五个。

The Increasing of Argument Positions

Arguments generally refer to the entities(NPS and its equivalents) which are connected with predicates. It is commonly assurned that there are at most three possible argument positions in a sentence, i.e. those of subject, direct object and indirect object. In fact, the number of arguments, their theta roles and distribution in the sentence are determined by the senses of predicates. The positions of complement and adverbial of a sentence should also be regarded as argument positions on condition that the elements in these positions are obligatory elements of the predicate. Then they can also be called arguments of the predicate, and the positions they occupy are argument positions as well. So it is argued that the argument positions should be increased from the original three to the present five.
