The acquisition of Chinese unaccusative verbs by Vietnamese-speaking learners
The present study examines the acquisition of Chinese unaccusative verbs by learners with Vietnamese background,employing a writing production task and a grammatical judgment task.The results show that:learners have difficulty in acquiring the argument structure of Chinese unaccusative verbs;learners have failed to acquire the semantic constraints of the post-positional NP of Chinese unac-cusative verbs;the prominence of semantic features affects learners'acquisition of the subclasses of Chi-nese unaccusative verbs.The findings suggest that Vietnamese learners fail to establish a complete knowledge representation of Chinese unaccusative surface structure,which do not support the prediction of the'Interface Hypothesis'.
