摘　　要：不同的任务条件影响任务的复杂度,从而影响语言产出的复杂性、准确性和流利性。本文采用实验研究方法,收集了36名中国EFL学习者在完成独白和对话任务时的口语流利性、复杂性和准确性特征以及口语整体得分,分析了任务条件、口语产出和分数之间两两交互的影响,结果表明:(1)任务条件影响口语产出,在完成对话任务时中国大学生的口语准确性和流利性增加;任务条件对口语复杂性既有正面又有负面影响;(2)当语言能力是测试目的而任务仅是诱导手段时,任务条件对分数不产生影响;(3)独白任务对分数的预测力高于对话任务;在口语产出的三个维度中,流利性对分数的预测力最大。Differences in task condition influence task complexity,resulting in differences in complexity,accuracy and fluency of oral performance.This experimental study analyzes 36 Chinese EFL learners’ linguistic features in fluency,complexity and accuracy and their holistic scores when they perform monologic and dialogic tasks,and explores the interactive effects between task condition,oral performance and test scores.The following findings are yielded.First,when performing the dialogic task,Chinese EFL learners improve their language in accuracy and fluency,while both positive and negative effects are found on complexity.Second,when language ability is tested with the task as an elicitation device,the task condition does not influence test scores.Third,the monologic task has higher predictive power of score than the dialogic task does,and among the three dimensions of oral performance,fluency is the best predictor of test scores.
