目前对英语中动结构的形成主要有词汇层面与句法层面两个方面的解释,词汇层面主要意见为中动结构是基础生成的,而句法层面则认为中动结构是移位生成的。分析的理论基础主要有GB、MP两大理论框架,本文认为在MP框架下对中动结构的解释更充分一些。 At present, the formation of English passive structures is mainly explained both in lexical and syntactic levels. The main opinion at the lexical level is that the middling structure is based, while the syntactic level holds that the middling structure is displaced. The theoretical basis of the analysis mainly includes two theoretical frameworks of GB and MP. This paper considers that the interpretation of the structure of the middle structure is more adequate under the MP framework.
