摘要
基于大学英语学习者语料库COLEC,作者首先采用WordSmith软件从COLEC语料库中提取所有3至6词词块,然后把词块按结构分为完整分句、分句成分和不完全词组3大类别,最后重点讨论各个类别词块的语用功能。统计结果表明:词块的分布为3词词块所占的比例最大,6词词块最少,即呈现词块的长度越大,数目就越少,使用频率也就越低的趋势;3种词块结构类型的分布情况是分句成分在所有词块中所占比例最大,超过50%,不完全词组次之,完整分句最少;大学生英语写作呈现词块结构多样化、语用功能丰富的特征。
Based on the College Learners＇ English Corpus-COLEC, the authors first introduce the methodology of extracting lexical chunks based on the length ranging from three to six words in COLEC; then classify lexical chunks into three broad structural categories： complete clause, clause constituent and incomplete phrase; finally put an emphasis on the pragmatic functions of each category of lexical chunks. Results show that： three-word chunks come first in number in COLEC, while six-word chunks the last; among the three structural types of lexical chunks clause constituents are the most frequently used type, showing the significance of this type of chunks in college English writing; the structures of lexical chunks are various and pragmatic functions are quite rich in college students＇ writing.
