摘　　要：本研究基于英语专业4个年级学习者的128篇同一主题作文,探讨分析学习者产出性词汇发展和词块运用差异及其与写作质量的关系。研究主要从词频分布、文本长度、句子数量、句内词数和词长等方面考察词汇发展,并主要针对3-5词词块分析词块运用。研究结果表明:(1)4个年级学习者普遍过度使用高频词,较少使用低频词,尽管学习者的词汇量随着英语水平提高而不断增加;(2)中低水平学习者倾向于使用简短单词写短句,高水平学习者复杂单词和长句运用能力明显增强;(3)低频词、文本长度、句子数量、句内词数与写作质量显著正相关;(4)中低水平学习者运用的词块与作文提示语高度复现,高水平学习者的词块运用则显著不同;(5)词块运用频数与写作质量显著负相关。Based on 128 writing texts on the same topic from English majors of 4 grades, this study investigates Eng- lish majors＇ differences in the development of vocabulary and the use of lexical chunks, and their relations with the writing quality. In the study, vocabulary development is analyzed in terms of vocabulary profile, text length, number of sentences, number of words in a sentence and word length, and the use of lexical chunks is examined by extracting and comparing 3-5 word lexical chunks. The results are as follows ： （ 1 ） high-frequency words are commonly over- used and low-frequency ones are underused in the texts, despite the fact that English majors＇ vocabulary increases with the improvement of their English proficiency; （2） pre-intermediate and intermediate learners tend to write short sentences with simple words, while advanced learners are more capable of using complicated words to write long sen- tences; （3） low-frequency words, text length, number of sentences and number of words in a sentence significantly positively correlate with the writing quality; （4） pre-intermediate and intermediate learners use repeatedly the lexical chunks from the writing prompt, while advanced learners use them far less ; （5） the frequency of lexical chunks sig- nificantly negatively correlates with the writing quality.
