Abstract:This paper applies relevant theories of postmodernism to analyze the core characteristics of the dissemination of English short videos, such as fragmentation, diversification and decentralization, as well as the impacts of these characteristics on English learning and cross-cultural communication. Meanwhile, it puts forward a series of feasible suggestions and countermeasures for the problems existing in the process of English short video dissemination, and on this basis, makes a rational prediction of its future development trends. In a word, this paper aims to provide solid theoretical support and practical guidance for the dissemination and development of English short videos, and further promote the innovation and development of English education and cross-cultural communication.
