近年来，在应用语言学领域的多语转向和积极转向双重背景下，幸福（wellbeing）已成为外语教育中的一个重要概念，提升学习者幸福感是外语教育的重要目标之一。因此，有研究者开始探讨二语学习对双语者幸福的积极影响。本文从幸福这一多维概念入手，首先对其构成要素进行简要介绍；然后基于双语者的定义和特征／ 优势，以实证研究为依据阐释二语学习对提升双语者幸福感的积极作用；最后对未来相关研究提出一些设想和建议。

In accordance with the multilingual turn and positive turn in the field of applied linguistics in recent years, well-being has become an important concept in foreign language education. As a result, promoting learner well-being is now explicitly deemed as one of the education goals. Triggered by this, some researchers began to explore the positive impact of second language (L2) learning on bilinguals’ well-being. Starting with the multi-dimensional concept of well-being, this article first gives a brief introduction to its theoretical background and components. Then, based on the unique advantages of bilingual learners, the positive role of L2 learning in improving bilinguals’ well-being is illustrated with empirical evidence. Finally, some suggestions are put forward for future research.
