【摘要】 本文通过声学实验和感知实验，从界面理论视角考察了英语母语者对汉语“哪里”疑问代词句的习得。“哪里”在特指、虚指和反问的不同语法功能的句子中，存在语法—韵律界面的双向互动，主要表现为句子的焦点信息和韵律特征具有较强的对应关系；学习者产出疑问代词句时出现重音错置或固化、重音凸显程度低、焦点后无压缩、句末音节时长延长、整体基频偏高及调域范围变窄等韵律偏误；学习者对疑问代词句的感知能力优于产出能力，语言水平与习得呈正相关。研究表明，界面假说理论将界面的内外之别与习得效果简单对应，不能全面解释所有界面及其特征的习得，学习者对疑问代词句的习得还与界面信息处理量、词语功能类别、母语迁移、语言水平等多种因素相关。更多还原

【Abstract】 This study investigates the acquisition of the Chinese interrogative pronoun “nǎlǐ” by English native speakers from the perspective of the interface theory, employing acoustic and perceptual experiments. The findings reveal a bidirectional interaction at the grammar-prosody interface in sentences where “nǎlǐ” serves different grammatical functions, namely specific reference, vague reference, and rhetorical questioning. Specifically, there is a strong correspondence between the focus information of the sentences and its prosodic features. During the production of interrogative pronoun sentences, learners exhibit various prosodic inaccuracies, including misplaced or fixed stress, reduced prominence of stressed syllables, lack of focus compression, prolonged syllable duration at the end of the sentence, elevated overall pitch, and narrowed pitch range. Notably, learners demonstrate superior perceptual abilities in comparison with their production capabilities regarding interrogative pronoun sentences, with a positive correlation between language proficiency and acquisition outcomes. The study suggests that the interface hypothesis, which correlates the distinctions between internal and external interfaces with learning outcomes, fails to comprehensively account for the acquisition of all interfaces and their characteristics. Furthermore, the acquisition of interrogative pronoun sentences is influenced by a multitude of factors, such as the processing load of interface information, the functional categories of words, native language transfer, and overall language proficiency.更多还原
