Based on the theta-role theory,this paper examines the problem from the angle of semantic variation of the verb,and proposes a new method of derivation.

The studies we reviewed in this article have demonstrated that,(a)SP can not be explained simply by lexical,thematic,or metrical similarity between prime and target;(b)The magnitudes of SP effects have been observed to be reduced if the prime and target contain different verb,different number of thematic roles,or different order of the roles;(c)both hiera.

In contrast with thematic roles,participants are an essential part of the system of transitivity which characterizes the functional linguistics.

The connotation of suf- fering/acquiring is attributable to the theta-roles assigned to the possessive-subject.

Questions regarding this structure are: How can the unaccusative verb take both a subject and an object? , What are the theta-roles played by the Possessor and the Possessee? , What Cases do the Possessor and the Possessee receive? and How is the PSPO.

It has a suppressed thematic role which is saturated in the lexicon.

The issues concerning traditional interpretation of thematic roles and newly established thematic theories have increasingly attracted attention from different interested linguistic groups.

On the basis of the relevant results, the paper puts forward a thematic role system and makes an analysis and statistics to the double object constructions with 452 DOC verbs.
