Abstract: Virtual simulation experiments, relying on computer, multimedia, and network communication technologies, construct highly realistic virtual business scenarios, providing an immersive learning experience for business English training. This paper explores their application in such courses. It first outlines the connotation of virtual simulation experiments, the objectives and characteristics of business English training courses, and the limitations of traditional training. Then, it analyzes the challenges faced in application, such as technical bottlenecks, insufficient teacher literacy, and difficulties in integrating teaching resources. Furthermore, it proposes countermeasures from three aspects: technical optimization and upgrading, teachers'professional development, and collaborative construction of teaching resources. The aim is to improve students'practical ability in business English, promote the innovation of teaching modes, and cultivate high-quality talents meeting the needs through improving the construction of virtual simulation experiments.
