基于多模态学术英语口语语料库的中国理工科大学生单词重音位移研究

基于自建多模态学术英语口语语料库对中国理工科大学生单词重音位移进行研究，分析了主要单词重音位移、主要单词重音位移分布、不同年级不同性别学生之间重音位移标准频数以及是否具有显著性差异。研究表明，单词重音位移主要发生在多音节词发音中，并且单词重音位移至第二音节的频次最多。从不同年级、不同性别学生之间的对比分析来看，一年级学生重音位移标准频数多于二年级学生，女生重音位移标准频数多于男生，但不同年级、不同性别学生之间重音位移均不具有显著性差异。在总结研究结果的基础上提出教学和学习建议。

A Study of Word Stress Displacement among Chinese Science and Engineering Majors Based on the Multimodal Corpus of Academic Spoken English

Based on the self-built Corpus of Academic Spoken English, this paper studies the word stress displacement of Chinese science and engineering majors, and analyzes the main word stress displacement, its distribution, the standard frequency of stress displacement among students of different grades and genders and whether there are significant differences. Results show that word stress displacement occurs mainly in multisyllabic words, and the highest frequency of word stress is displaced to the second syllable. The comparative analysis reveals that the standard frequency of stress displacement is more among first-year and female students than second-year and male students, yet there are no statistically significant differences among students of different grades and genders. Accordingly, suggestions for teaching and learning are made.
