【摘要】 本文通过句子语义匹配判断任务和图片描述判断任务两项实验,拟考察不同类型受试在不同谓词结构进行短语转化的习得情况,进而为二语习得中投射原则和映射原则的可及性及相关形式特征的习得提供一定实证数据支撑。研究结果发现:1)投射原则和映射原则的直接可及性在二语习得的初期即已显现,并贯穿二语习得全过程。2)相关形式特征习得受制于个体特征习得顺序和复杂特征重组,但最终可完全习得。总体来看,特征习得可由特征组装理论进行阐释。更多还原

【Abstract】 The present study,by conducting two experiments,i. e.,semantic match judgment task and picture description judgment task,attempts to investigate issues concerning accessibility of the mapping and projection principles and related feature reassembling among second language learners of different proficiency in the process of second language acquisition( SLA),focusing upon the conversion from predicate to phrase structures. The results were as follows,1) The projection principle and mapping principle are proved to be directly accessible in the early stage of SLA and in the whole process of SLA; Thus,the acquisition is constrained by the relevant principles. 2) The progress of the concerning acquisition process is constrained by the acquisition sequence of the single feature and the reassembling of the complex features,and all these features can be fully acquired; Thus,the present study gives support to the hypothesis of the feature assembling.更多还原
