中国学生很容易习失英语的空主语,但对英语空宾语的习失则较少发生,本文对中国学生英语中的这种不对称性现象进行了梳理。文章首先在原则与参数理论框架内对空主语和空宾语进行了理论阐述,并对英汉语中的空主语和空宾语进行了跨语言比较,然后对中国学生习失英语空主语和空宾语的不对称性现象研究进行了介绍和评价,最后指出在这个领域可以开展的研究。 It is easy for Chinese students to get used to the empty subject of English, but the loss of English empty object is less likely to happen. This article sorts out the phenomenon of this asymmetry in Chinese students’ English. The article first elaborated the theory of empty subject and empty object in the framework of principle and parameter theory, and made a cross-language comparison of the empty subject and empty object in English and Chinese, and then used Chinese students to learn English empty subject and empty object. The research on asymmetry phenomena was introduced and evaluated. Finally, the research that can be carried out in this field was pointed out.
