According to modern syntactic study,one place predicate sentence can be divided into unergative sentence and unaccusative sentence.

It therefore defends, in so doing, the so-called unaccusativity hypothesis of existential verbs , and unifies the predicative verb class in existential constructions in natural langu.

This dissertation presents a contrastive study on unaccusativity in the generative framework, holding that the traditional intransitives in Chinese should also be classified as unergatives and unaccusatives.

Such errors are sensitive to verb unaccusativity strength which is presupposed in the study; 2.

A Cognitive Constructional Account of Unaccusative Phenomena in English and Chinese;

It is widely accepted that the verbs in existential sentences(ES) and EPC are unaccusative verbs.

This paper starts with the formation conditions of double-object clause, divides this pattern into normal and abnormal categories, pays a close attention to the formation conditions of abnormal double-object patterns and their syntactic and semantic features, and explores the condition meaning of abnormal double-object patterns on the basis of construction grammar.

An analysis of the theoretical exploration into unaccusative verbs;

This paper briefly introduced the difference between unaccusative verbs and unergative verbs,and mainly studied the unaccusative verbs in English and Chinese respectively,aiming to describe their features in detail.

English and Chinese form a superset-subset relation in terms of unaccusative verbs and psych verbs:English allows causative-alternating unaccusative verb,but Chinese does not; English allows both subject-experiencer and object-experiencer psych verbs,whereas Chinese only allows the former.
