Twenty years ago, a state-of-the-art review inSSLAmarked the coming of age of the study of temporality in second language acquisition. This was followed by three monographs on tense and aspect the next year. This article presents a state-of-the-scholarship review of the last 20 years of research addressing the aspect hypothesis (AH) (Andersen, 1991, 2002; Andersen & Shirai, 1994, 1996), the most tested hypothesis in L2 temporality research. The first section of the article gives an overview of the AH and examines its central tenets, and then explores the results of empirical studies that test the hypothesis. The second section considers studies that have investigated four crucial variables in the acquisition of temporality and the testing of the AH. The third section discusses theoretically motivated areas of future research within the framework of the hypothesis.

近 20 年 L2 过去形态学的方面假设和获得

二十年前，一项最先进的审查在SSLA标志着第二语言习得中时间性研究时代的到来。紧随其后的是第三年关于时态和方面的三部专着。本文介绍了过去 20 年研究解决方面假设 (AH) (Andersen, 1991, 2002; Andersen & Shirai, 1994, 1996) 的研究现状，这是 L2 时间性研究中测试最多的假设. 本文的第一部分概述了 AH 并检验了其核心原则，然后探讨了检验该假设的实证研究的结果。第二部分考虑研究了在时间性获得和 AH 测试中调查了四个关键变量的研究。第三部分在假设的框架内讨论了未来研究的理论驱动领域。
