摘　　要：生成式人工智能(AI)在学术写作中的应用正引发传统写作教学模式转型升级,然而AI赋能学术写作的研究不足。词块作为语篇中重现的连续多词序列,具有鲜明的体裁和学科特征。基于此,采用语料库方法探究AI和学者在化学国际期刊论文英文摘要中四词词块使用特征。结果显示,AI比学者更依赖词块构建摘要,但词块多样性不足,且不符合of短语为主的学术写作惯例。在结构上,AI偏重小句类词块,学者更倾向短语类词块。在功能上,2者均偏重研究导向词块,但AI过度依赖文本结构导向词块,框架和立场词块不足,表达单一。这源于生成式AI预训练模型的本质,使其缺乏个性化与学术推销性修辞表达。研究能够提升化学学者词块使用意识,推动化学人机协同学术英语写作教学。The application of generative artificial intelligence(AI)in academic writing has been driving a transformation in traditional academic writing instruction.However,little research has been done on the ways in which AI assists in academic learning.Lexical bundles,as key components of academic writing,are defined as recurrent multi-word sequences and serve as distinguishing feature of discourse across genres,and disciplines.Adopting a corpus-based approach,this study examines the convergent and divergent usage of 4-word lexical bundles between AI-generated and scholar-written English abstracts in international chemistry journal articles.The results show that AI relies more heavily on lexical bundles but exhibits limited bundle diversity in constructing chemistry abstracts,while does not conform to the English academic writing convention that dominated by of-phrases.Structurally,AI prefers clausal bundles,while scholars favor phrase-based bundles.Functionally,both AI and scholars prioritize research-oriented bundles.Nevertheless,AI overuses text-structuring bundles while under-utilizing framing and stance bundles.These limitations reflect the inherent constraints of generative AI pretraining models,which lack personalization and the rhetorical sophistication required for effective academic persuasion.This study underscores the importance of raising chemistry scholars'awareness of lexical bundles and advancing AI-human collaboration of academic English writing instruction in the field of chemistry.
