Previous studies on the acquisition of semantics in the aspectual domain have suggested that a difficult case for achieving a targetlike representation in a second language arises when learners need to preempt a first language (L1) option (Gabriele, 2009). This study investigates this issue by focusing on a learning scenario where predicate-level variability exists in the L1 input. We investigate whether Japanese learners of English can learn to invalidate event cancellation readings (Tsujimura, 2003) in English and how such knowledge develops with increasing English proficiency. We address these questions by examining how Japanese learners of English interpret accomplishment predicates that allow an event cancellation reading in Japanese but not in English. A truth-value judgment task was administered to 60 beginner, 96 intermediate, and 40 advanced Japanese learners of English as well as 20 L1 English and 20 L1 Japanese speakers. Our results showed that Japanese learners of English progressed toward a targetlike representation of aspectual entailment. We argue that such progress follows two parallel routes: a grammatical route rooted in the learners’ growing awareness of the English determiner and number morphology combined with a statistical route rooted in the learners’ inferences based on missing data.

L2方面的习得：日本英语学习者事件完成的计算

先前关于方面域语义获取的研究表明，当学习者需要抢占第一语言 (L1) 选项时，会出现在第二语言中实现目标类表示的困难案例 (Gabriele, 2009)。本研究通过关注 L1 输入中存在谓词级别可变性的学习场景来调查这个问题。我们调查了日本的英语学习者是否可以学习使英语中的事件取消读数无效（Tsujimura，2003），以及这种知识如何随着英语水平的提高而发展。我们通过研究英语的日本学习者如何解释成就谓词来解决这些问题，这些谓词允许用日语而不是英语阅读事件取消。对 60 名初学者、96 名中级者进行了真值判断任务，和 40 名高级日语学习者以及 20 名 L1 英语和 20 名 L1 日语人士。我们的研究结果表明，日本的英语学习者朝着方面蕴涵的目标表示发展。我们认为，这种进步遵循两条平行的路线：一条植根于学习者对英语限定词和数字形态意识不断增强的语法路线，以及一条植根于学习者基于缺失数据的推断的统计路线。
