Examining the formulation and implementation of language policies at various levels, including governmental, institutional, and educational settings, falls within the purview of applied linguistics. This involves considerations of language standardization, official languages, and language-in-education policies.

检查各个层面（包括政府、机构和教育环境）语言政策的制定和实施属于应用语言学的范围。这涉及到语言标准化、官方语言和教育语言政策的考虑。

Applied linguistics seeks to bridge the gap between linguistic theory and real-world applications. It emphasizes the integration of theoretical insights with practical solutions in areas such as language teaching, translation, and language policy (Cook and Seidlhofer, 1995).

应用语言学致力于弥合语言理论与现实应用之间的差距。它强调理论见解与语言教学、翻译和语言政策等领域的实际解决方案的结合（Cook 和 Seidlhofer，1995）。

Not Limited to Language Education: While research in language education is a core component of applied linguistics, its scope extends beyond this. It covers areas such as language policy, translation, language pathology, machine translation, language planning, and more.

虽然语言教育研究是应用语言学的核心组成部分，但其范围超出了这一范围。它涵盖语言政策、翻译、语言病理学、机器翻译、语言规划等领域。

Over time, applied linguistics has adapted to meet the changing needs of society. It has expanded its scope beyond language education to address broader societal issues, such as language policy, cross-cultural communication, and language planning (Hall et al. , 2011).

随着时间的推移，应用语言学已经适应了社会不断变化的需求。它已将其范围扩展到语言教育之外，以解决更广泛的社会问题，例如语言政策、跨文化交流和语言规划（Hall 等，2011）。
