| This paper is based on"three planes"theory, by taking Bei-sentence and unmarked patient-subject sentence in Modern Chinese as the research object. We analyze and compare the two sentence patterns on syntactic,semantic and pragmatic levels.On the syntactic plane,we discuss the syntax structure and syntactic features of Bei-sentence and unmarked patient-subject sentence.We find that subject ellipsis or no subject is a common phenomenon in Bei-sentence but not in unmarked patient-subject sentence.The bare-verb can be the predicate verb of Bei-sentence in the sentence pattern of "Bei...suo...". From the semantic perspective,we analyse the semantic roles,semantic features, semantic color and semantic selectional restrictions of the the two sentence patterns.We find the subject of Bei-sentence mostly are animate nouns, and the subject of unmarked patient-subject sentence mostly are inanimate nouns."Bei" has some unique semantic features, for instance unfortunate emotion, intense passive meanings and causality. And also, we study the pragmatic functions from the pragmatic plane,such as topical function,discourse focus,discourse expression.We analyze and compare the constructional sense of Bei-sentence and unmarked patient-subject sentence.At last,we could do the transformation of the two sentence patterns,and get the transformational restrictive condition. |
