本文通过从语料库中提取语料,从偏误的语法分类的角度进行分析,得出目的语负迁移是中高级阶段留学生在“由”字句习得过程中造成偏误的主要原因;提出全面认识偏误本质、理性知识和感性知识相结合、对比分析等方法,希望对对外汉语教学实践有所启发。 In this paper, the corpus is extracted from the corpus and analyzed from the perspective of the wrong grammatical classification. It is concluded that the negative transfer of the target language is the main reason that the foreign students make errors in the acquisition of the “” clause by middle and high-class students. Understand the nature of error, the combination of rational knowledge and perceptual knowledge, comparative analysis and other methods, hoping to inspire the practice of teaching Chinese as a second language.
