摘　　要：作为科技论文的重要组成部分,是科研成果走向国际的通行证。本文基于自建的小型语料库,详细分析了中国学者科技论文英文摘要语篇中,各语步所使用的词块结构及其语篇功能的特点。结果表明,各语步有其典型的词块结构型式,并成为特定语篇功能的标志,但是由于中国理工科作者对英文摘要语篇语体的认识不足以及文化背景因素的制约,出现了背景语步和结论-讨论语步的缺失,各类词块在不同语步上的分布也很不均匀等情况。function as a unique type of academic discourse and play an important role in delivering the key information of academic articles to readers, in which lexical chunks show unique features in terms of both structure and function. Resorting to self-built corpora, we conducted a study on types and functions of the most frequently used chunks and their distributions in moves of English abstracts of science and technology papers by Chinese researchers. The result indicates that each move has its typical lexical chunks, which serve for the particular discourse functions. However, due to lacking understanding of the stylistic feature of the English abstract, compounded with the constraints of cultural background, "Background Move" and "Conclusion-Discussion Move" are often missing and the distribution of various types of lexical chunks in different moves is also uneven in abstracts of science and technology papers by Chinese researchers. This study may provide some guidance and reference for academic writing and EAP teaching.
