| 摘要: |
| 基于科技期刊英语摘要语料库,考察科技论文英语摘要中出现频率较高的四词词块,并对高频词块的结构和功能进行分类和分析。结果显示,摘要中的四词词块有独特的结构特点和语用功能。在结构上以介词词块和名词词块居多,动词词块和完整序列也占有相当比重。这些词块还承载了不同的语用功能,以研究类词块和语篇框架类词块为主。词块的选择体现摘要各语步不同的功能和交际目的。研究同时揭示,词块的结构和意义存在相当大的关联,将两者有效地结合起来,更有利于词块知识的学习和运用。 |

| Abstract: |
| This study examines the frequently used four-word lexical bundles in English abstract corpus of scientific and technical journals. The most frequent four-word lexical bundles were identified and classified structurally and functionally. The results show that four-word bundles in abstracts have their unique structural and functional characteristics. Prepositional and nominal bundles take up more than half of all the bundles. Verbal bundles and complete sequence also account for a large part in the corpus, which carry different functions, reflecting different communicative purposes of abstract moves. Research-oriented and text-oriented bundles play a central role. The study indicates a close relationship between the structure and the function of these bundles. Combination of them will facilitate the acquisition and use of lexical bundles. |
