英语方位介词意义习得的认知分析及教学启示

英语中的介词数量多而且大多数都是多义词，但这些意义都是相互联系的。从认知语义学的角度分析，一个介词意义的扩展是从最初表示的方位意义到表示抽象概念的一个过程，介词所表示的方位意义是介词意义扩展一隐喻化的重要过程的基础。文章主要从认知语义学的角度通过简单的英汉对比来浅析方位介词意义的扩展及其对汉语为母语的英语学习者带来的影响，希望能够在日常的介词教学中帮助学生准确生动地理解介词的隐喻意义，促进介词的习得和使用。

Acquisition of English Prepositions From Cognitive Perspective and Its Implications for Preposition Teaching

English prepositions are great in number and most of them have more than one meaning. These meanings of a proposition are different but closely related. From a cognitive semantic perspective, the original meaning of a proposition is orientation, from which other abstract meanings are developed. In everyday proposition teaching and learning, students should be guided to paying more attention to how the abstract meanings of a proposition are related to the prototype meaning, because it is the basis for meaning motivation-metaphor. This paper, from the cognitive semantic perspective, tries to analyze how the meanings of an orientational proposition are developed from the prototype meaning with the hope that this analysis can bring help in proposition teaching and learning.
