本研究基于中国学生英语口笔语语料库的说明文写作部分,从使用频数,多样性和准确性,对比分析了三组不同水平的实验对象的动词词块使用特点。研究结果表明:随着语言水平的提高,实验对象动词词块使用频数在上升,多样性在增大,但是准确性反而降低。其中使用有误的语块可以分为语法错误型和搭配不当型。鉴于以上研究结果,外语教学中应深化词块教学,同时加强策略学习的培养。
In this study, based on the explanatory part of Chinese students’ oral English writing corpus, the author analyzed the usage characteristics of the verb phrases of three different levels of subjects from the aspects of frequency of use, diversity and accuracy. The results show that with the improvement of language proficiency, the frequency of use of lexical chunks in experimental subject is increasing, while the diversity is increasing, but the accuracy is decreasing. The use of the wrong language block can be divided into grammatical error type and with improper type. In view of the above research results, we should deepen lexical teaching in foreign language teaching and strengthen the cultivation of strategy learning.
