基于语料库的汉语作为第二语言“是”字句习得研究

该研究基于中介语对比分析方法，通过语料库考察现代汉语与二语学习者不同学习阶段中介语“是”字句的分布特 征，旨在揭示二语习得规律并为汉语第二语言教学提供参考。研究从现代汉语语料库及中介语语料库取样，对比分析“是”字句 的使用频率与类型分布。 结果显示现代汉语“是”字句高频类型为等同关系、类属关系、情况说明，受意合特征与整体思维影响 显著；中介语“是”字句随学习阶段动态发展，初级阶段以简单句型为主，中级阶段扩展至 9 类，新增比喻、应答功能类，高级阶 段向目的语趋近，但仍存在思维习惯差异。 研究认为，汉民族整体思维与意合表达是中介语与目的语差异的核心原因，建议教 学中采用“阶段适配”策略，强化语境省略与主观评价功能训练。

Based on the contrastive interlanguage analysis method, this study investigates the distributional characteristics of shi constructions in modern Chinese and interlanguages of second language learners of Chinese at different stages through corpus analysis, aiming to reveal the principles of second language acquisition and provide references for second language teaching of Chinese. The study selected language materials from modern Chinese corpora and interlanguage corpora to comparatively analyze the usage frequency and type distribution of shi constructions. Results show that the high-frequency types of shi constructions in modern Chinese include equivalence relations, categorization relations, and situation explanations, which are significantly influenced by the paratactic features and holistic thinking of the Chinese language. Shi constructions in interlanguage develop dynamically with learning stages: learners at elementary level primarily prefer simple sentence patterns. Types of shi construction expanded to 9 at the intermediate stage with the emergence of metaphorical and responsive functional types. Advanced learners approach the target language but retain differences in thinking habits. The study concludes that the holistic thinking and paratactic expression of the Chinese nation are the core reasons for differences between interlanguage and the target language. It suggests adopting a "stage-appropriate" teaching strategy, emphasizing training in contextual ellipsis and subjective evaluation functions.
