【摘要】：近年来对语料库数据的研究日益增多,语言中出现的多词单位受到越来越多的关注。然而对于多词单位的界定却无统一的认识,国内也存在译法不一的情况,因此本研究将多词单位命名为“词块”,其定义为连续的二词或者二词以上频繁共现于多个文本中的词语组合。参照Biber等人对词块的结构和功能分类,本研究将EFL高级英语学习者的MA论文和英语本族语者的学术杂志论文中的三词词块进行对比,以探讨英语专业硕士研究生三词词块的使用特点。本研究采取定量和定性相结合的方式进行研究,研究结果显示,总体看来,高级英语学习者能够频繁使用大量的三词词块,并且两个语料库中的词块结构分类和功能分类相似。从结构上看,学习者和本族语者词块可分为五类：名词类,介词类,动词类,从句类和其他类词块；从功能上看,可分为三类：指示类,立场类和篇章组织者类词块。通过对比研究发现,两者使用词块的方式存在较大的差异。从结构上看,与本族语者相比,首先高级英语学习者过多的使用了名词类词块和介词类词块,其中有相当一部分词块与论文研究题目相关,而且一些词块未出现在本族语者词块中；其次动词类词块具有汉语语法的特征,例如过多使用主动语态；最后从句类词块表现出了较少的变化性,学习者词块中虽然出现了that, which,as引导的从句,但是却多用that,较少使用which, as引导的从句。从功能上看,与本族语者相比,首先高级英语学习者较少使用了指示功能词块中的量化类词块,例如the degree to;其次高级英语学习者对立场类词块中的模糊限制语使用较少,虽已掌握这类语言特征,但却缺少灵活性和变化性；最后高级英语学习者已经意识到篇章组织者类词块的重要性,因此在写作过程中加以运用,但使用过于频繁,出现了一种泛化的现象。另外进一步研究发现学术杂志库中出现的词块在学习者库中的使用率低于50%,而且这些词块在学习者库中还存在过度使用和使用不足的情况。因此本研究对于改进英语专业硕士生的论文写作具有指导性意义,同时可对英语词块的教学提出切实可行的建议及措施。
[Abstract]:In recent years, more and more researches have been made on corpus data, and more and more attention has been paid to the emergence of multi-word units in language. However, there is no uniform understanding of the definition of multi-word units, and there are different translation methods in China. In this study, the multi-word unit is named "lexical chunks", which is defined as the combination of two or more consecutive words in multiple texts. According to the structure and function of lexical chunks by Biber et al. In this study, we compared the MA thesis of EFL advanced English learners with the three word chunks published by native English speakers in order to explore the characteristics of the use of three word chunks in postgraduates majoring in English. The results show that advanced English learners are able to use a large number of three-word chunks frequently. The lexical chunks in the two corpora are similar in structure and function. Structurally, lexical chunks of learners and native speakers can be divided into five categories: noun, preposition, verb, clause and other lexical chunks. There are three types of lexical chunks: demonstrative category, position type and text organizer type. Through comparative study, it is found that there are great differences in the way of using lexical chunks between them. In terms of structure, compared with native speakers, first of all, advanced English learners use noun and prepositional lexical chunks too much, and a considerable number of them are related to the topic of the thesis. Moreover, some lexical chunks do not appear in native lexical chunks; second, verb lexical chunks have the characteristics of Chinese grammar, such as excessive use of active voice; finally, clause lexical chunks show less variation. Although that, which as led clause appears in the lexical chunks of learners, they often use that clause, which is less used than that one. From a functional point of view, compared with native speakers, first, advanced English learners use less quantitative lexical chunks in demonstrative functional chunks, such as the degree to, and second, advanced English learners use less hedges in position lexical chunks. Although these linguistic features have been mastered, they lack flexibility and variability. Finally, advanced English learners have realized the importance of lexical chunks as text organizers, and have therefore used them in the writing process, but they have used them too frequently. Furthermore, it is found that the usage rate of lexical chunks in academic journals is less than 50%, and that there is overuse and underuse of lexical chunks in learners' libraries. Therefore, this study is of instructive significance for improving the writing of English master students, and can also provide practical suggestions and measures for the teaching of English lexical chunks.
