Abstract Lexical bundles have been found to be of considerable significance in academic texts. EAP instructors and students alike are thus encouraged to pay careful attention to these multi-word units in their teaching and learning process, respectively. There are several reports as to the discipline sensitivity of these multiword units, but their variations within the same discipline are underexplored. This paper investigated the forms and functions of 4-word lexical bundles in a 5.7 million word corpus of textbooks, research articles and theses in the discipline of applied linguistics to shed new light on their intradisciplinary variations across the three genres. Our analyses revealed that while bundles vary substantially across different genres in the same discipline, there are still significant commonalities that genres within the same discipline share. Our findings are theoretically insightful as they challenge the generality-specificity dichotomy in EAP by showing that neither side can override the other in its importance. The results also have pedagogical implications for EAP practitioners by drawing their attention to the significance of both discipline and genre in teaching lexical bundles.

应用语言学论文、文章和教科书中的词汇包：研究跨学科的统一性和变异性

摘要 词汇束已被发现在学术文本中具有重要意义。因此，鼓励 EAP 教师和学生在他们的教学和学习过程中分别注意这些多词单元。有几份关于这些多词单元的学科敏感性的报告，但它们在同一学科内的变化尚未得到充分探索。本文研究了应用语言学学科教科书、研究文章和论文的 570 万词语料库中 4 词词汇束的形式和功能，以揭示它们在三种类型的学科内变化。我们的分析表明，虽然同一学科的不同流派之间的捆绑包差异很大，同一学科内的流派仍然存在显着的共性。我们的研究结果在理论上很有见地，因为它们通过表明任何一方都不能在重要性上超越另一方，从而挑战了 EAP 中的普遍性-特异性二分法。通过让 EAP 从业者注意学科和体裁在词汇束教学中的重要性，结果也对 EAP 实践者具有教学意义。
