摘　　要：作者从文本分析的角度,运用定量分析的手段对比分析了网络环境下不同的任务类型对学生作文语言特征的影响。体裁变量(记叙文、说明文、议论文和评论文)、互动变量(有任务互动与无任务互动)和任务结构变量(有任务结构与无任务结构)构成不同类型的写作任务。结果显示:(1)不同体裁的作文文本在准确度和复杂度方面存在显著差异;(2)有任务互动的作文文本语言复杂度明显高于无任务互动的作文文本;(3)无任务结构的作文文本语言复杂度高,但语言准确度相对较低,语法错误率出现的概率也比较大。From the perspective of text analysis,this paper uses a quantitative method to make comparative analysis of effects of web-based task types on linguistic features of essays written by EFL learners.Task types involve such variables as genres,interaction and structure.The research has shown the following results：（1） there are statistical signifi cant differences in language accuracy and language complexity in students’ writings in tasks with different genres;（2） there is a higher level of language complexity in students’ writing in tasks with interaction than in tasks without interaction;（3） there are much higher levels of grammatical complexity and lexical complexity in students’ writing in non-structured tasks than in structured tasks,but grammatical accuracy of non-structured tasks is lower than that of structured tasks.
