摘　　要：本文基于节奏多维特征模型,量化不同口语任务类型下中国英语学习者与本族语者的话语节奏模式差异,从而揭示中国英语学习者的节奏习得特点及规律。研究发现:1)无论是何种类型的口语输出,造成学习者节奏障碍的原因不只是来自轻重节拍的时长失调,更是源于对话语内部停延规律的随意处置以及音高起伏度的调控不足;2)由于言语加工策略的不同,口语任务类型会影响学习者多个韵律层级的节奏量化指标,因此学习者在输出不同类型的话语时,其节奏障碍的核心症结并不相同。其中,在朗读口语中,对话语停顿时长的调控失误是学习者最突出的问题,其次是对元音各项特征变量的失调;而在自发性口语中,核心症结则表现在对音节及辅音各项特征变量的调控不力。Under the framework of the multi-dimensionality and language-specificity of rhythm,this paper examines how Chinese EFL learners perform speech rhythm in connected discourses elicited by different oral tasks,with the aim to unravel the acquisition profiles of discourse rhythm in Chinese EFL learners’speech.The results show that:1)in addition to deficits in syllable timing,Chinese EFL learners are generally arbitrary in utilizing pausing strategies and in manipulating overall pitch variation when they produce discourse speech;2)due to the different cognitive loads of speech plan,an oral task does exert a great impact on rhythm metrics at different levels of the discourse,thus leading to different critical problems in discourse rhythm production by Chinese EFL learners.In reading-aloud speech,Chinese EFL learners faced great challenges in modulating pause durations as well as various vocalic parameters,while in spontaneous speech showing difficulties,in various syllabic and consonantal parameters.
