二语习得中的同构映射现象研究

语言习得研究发现，二语习得者最初很容易接受所学语言的典型语序。文章基于IMH假想，通过对宁波某高校来自墨西哥的留学生以及该校非英语专业本科大二学生的调查测试，对同构映射句型与非同构映射句型的习得情况进行了对比研究。研究证实，在二语习得的过程中，人脑中的语言处理机制会优先关照语序，二语学习者易于接受的句子所包含的NP语序均反映相关事件发生方式，即L2学习者更容易接受和习得语序与事件序列同构的句型。

An Analysis on Isomorphic Mapping Hypothesis in SLA

According to the relevant SLA researches, it is likely for learners to acquire the canonical orderwhen they begin to learn a second language. This paper, based on Isomorphic Mapping Hypothesis（IMH） and a survey to the Chinese non-English major sophomores and Spanish-native-speaker students in Ningbo from Mexico, analyses the manners in which the L2 learners acquire the isomorphic and non-isomorphic structure, and confirms that the language management mechanism in human brain makes in the process of SLA a preference of canonical order, i.e., the L2 learners make preference in understanding and acquiring the sentence pattern in which the canonical order is isomorphically mapped by the event sequence.
