词汇作为语言的基石,二语词汇的附带习得是二语习得中的重要研究课题。依靠没有人为干预的单纯阅读方式进行词汇附带习得,速度慢、效率低。为提高学习效率,加强人为干预和设计高质量的阅读任务成为必然。“投入检验量假设”为设计高质量的阅读任务提供了科学的测量理论基础。本文对二语词汇附带习得和“投入量检验假设”理论进行了简要的阐释,并简述了投入量检验假设是如何在二语词汇附带习得中应用的。一、引言 Vocabulary as a cornerstone of language, incidental acquisition of second language vocabulary is an important research topic in second language acquisition. Vocabulary learning is based on simple reading without human intervention, which is slow and inefficient. In order to improve learning efficiency, it is necessary to strengthen human intervention and design high-quality reading tasks. “Put the test hypothesis ” provides a scientific measurement theory basis for designing high-quality reading tasks. This paper gives a brief explanation of the incidental collation of L2 vocabulary and the hypothesis of “test of input quantity”, and briefly describes how input hypothesis is applied to incidental collation of L2 vocabulary.
