作為一種重要的語言現(xiàn)象,模糊限制語具有靈活、獨(dú)特的語義和多種語用功能。因此,無論是在口語還是書面語中,模糊限制語總是發(fā)揮著重要的作用。然而,對于二語學(xué)習(xí)者而言,正確恰當(dāng)?shù)厥褂媚：拗普Z仍是一件困難的事情。目前,國內(nèi)外關(guān)于二語學(xué)習(xí)者模糊限制語的研究主要集中在模糊限制語的習(xí)得結(jié)果上,對其習(xí)得過程的關(guān)注較少。Ellis在2014年提出,二語習(xí)得的發(fā)展已經(jīng)不再被認(rèn)為是一個靜態(tài)的或線性的表征系統(tǒng),而動態(tài)系統(tǒng)理論的提出為解釋二語習(xí)得過程中語言動態(tài)發(fā)展的非線性特征以及個體變異等關(guān)鍵問題提供了有效途徑。動態(tài)系統(tǒng)理論主要探討系統(tǒng)發(fā)展過程中不同成分交互作用所引起的動態(tài)變化,它對傳統(tǒng)的研究,尤其是靜態(tài)形式的研究產(chǎn)生了極大影響。運(yùn)用到二語習(xí)得的研究中,動態(tài)系統(tǒng)理論將二語習(xí)得研究視角從傳統(tǒng)的語言本身研究轉(zhuǎn)移到以發(fā)展為特征的學(xué)習(xí)者行為上。鑒于此,本研究在前人研究的基礎(chǔ)上,運(yùn)用動態(tài)系統(tǒng)理論,旨在研究中國英語學(xué)習(xí)者模糊限制語的習(xí)得過程。具體而言,本研究選取中國英語專業(yè)學(xué)生為研究對象,探討了其模糊限制語習(xí)得過程中所具備的特征,主要研究三個問題:（1）在模糊限制語習(xí)得過程中,中國英語專業(yè)學(xué)生在其頻次和種類上有何總體發(fā)展特...
