本文關鍵詞：學術論文語篇中語塊使用對比研究

【摘要】：語塊(lexical bundles)是指以一定結構高頻出現(xiàn)的且具有一定意義、長短不一的詞語片段,有助于語言產(chǎn)出的準確性、流利性、地道性�；谡Z料庫的研究發(fā)現(xiàn),學術語篇中使用的語塊具有特定的結構和功能特征。目前,國內(nèi)外學者多關注口語和書面語語塊對比研究、本族語者和二語學習者語塊對比研究,但此類研究中使用的語料庫涵蓋多種語言使用場景和學科,對語塊特征描述和解釋也不夠充分,因而對二語教學啟示比較局限。同時,就特定學科下英語學術語篇中的語塊研究數(shù)量較少。因此,本文選取應用語言學學科下中國英語專業(yè)研究生和本族語學者的英文學術論文,建立兩個語料庫(約200萬詞),比較兩者使用四詞語塊的分布、結構和功能特征,并解釋語塊使用差異產(chǎn)生的原因。本文基于語料庫檢索結果,對兩組作者使用頻率最高的50組四詞語塊進行定量、定性分析,發(fā)現(xiàn)英文學術論文中,中國學習者語塊結構、功能總體分布情況接近本族語學者,但學習者的高頻四詞語塊往往不為本族語學者所用。結合語境分析發(fā)現(xiàn),二者在語塊使用上存在較大差異。結構上,中國學習者更加依賴"VP-based"語塊,極少使用"relative-clause"語塊；功能上,其語塊選擇往往受母語影響,語塊習得中的負遷移現(xiàn)象依然存在；過于注重語篇構建的技巧,語塊使用缺乏語用品質和語用意識；“學術新手”身份凸顯,影響語塊選擇和使用。研究發(fā)現(xiàn)表明,中國英語專業(yè)研究生的語塊使用問題依然存在,前人語塊研究中的一般性發(fā)現(xiàn),也不完全與特定學科下學術語篇語塊特征相一致。該研究有助于總結本族語學者學術語篇中語塊結構和功能特征,了解中國英語學習者在語言、語用層面普遍的語塊使用問題,對外語語塊教學、學習者語塊意識的提高和教材編寫改進等方面具有實際意義。
