基于英语专业大学生议论文中情态序列的使用倾向的研究成果,本文着重探讨情态序列的使用倾向与其在校学习时间的关系。结果发现:1)情态动词的使用倾向与其在校学习时间无关;2)认知、义务情态序列使用倾向与其在校学习时间无关。同时,研究对结果进行了解释。研究为了解中国外语学生习得情态动词现状提供了参考,并为情态动词教学提供了建议。 Based on the research results of the tendency of the use of modal sequences in the thesis of English majors, this article focuses on the relationship between the tendency to use modal sequences and their study time in school. The results show that: 1) the tendency of using modal verbs has nothing to do with their learning time in school; 2) the tendency to use cognitive and obligatory modal sequences has nothing to do with their learning time in school. At the same time, the study explained the results. The study provides a reference for understanding the present situation of modal verbs acquired by Chinese EFL learners and provides suggestions for modal verb teaching.
