【摘要】：本研究在认知假说的理论基础上,考察汉语二语学习者在完成以输出文本类型要求和交际方式两个维度进行排列组合的八组任务时词汇复杂度的表现。词语复杂度从词汇多样性和词汇难度两个方面进行考察,其中词汇难度以词频序值和词汇等级两种标准进行测量。结果显示,不同文本类型和交际方式所输出的词汇在词汇多样性和词汇难度上都有显著差异。议论性任务输出的词汇最多,但难度最低;描述性任务输出的词汇最少,也最贫乏,但词汇难度最高;介绍性任务中用词最丰富。学习者在对话任务中所使用的词汇不仅比在独白任务中多,也更丰富,但词汇难度低于独白任务。不同复杂度的任务所输出的词汇在词汇多样性上存在显著差异,较复杂任务的词汇多样性低于较简单的任务;但任务的复杂度对词汇难度没有影响。
[Abstract]:Based on the theory of cognitive hypothesis, the present study examines the lexical complexity of Chinese second language learners (L2) when they complete eight groups of tasks arranged according to the two dimensions of output text type and communication style.Lexical complexity is investigated in terms of lexical diversity and lexical difficulty, in which lexical difficulty is measured by word frequency order and lexical level.The results show that there are significant differences in lexical diversity and lexical difficulty among different text types and communication styles.The vocabulary output of argumentative task is the most, but the difficulty is the lowest; the descriptive task output the word is the least and the most poor, but the vocabulary is the most difficult; the most abundant words are used in the introductory task.Learners not only use more words in dialogue task than in monologue task, but the vocabulary is less difficult than monologue task.There are significant differences in lexical diversity between tasks with different complexity, and the lexical diversity of more complex tasks is lower than that of simple tasks, but the complexity of tasks has no effect on lexical difficulty.
