Futures Studies conceptualized in 1940, from 1960 to 1970 went through the peak of development in Philosophy of Science. The main proponents of Philosophy of Science, such as Positivism, Postpositivism and Critical Realism deeply influenced the futurists' ideas of the time concept in Future Studies. The understanding of time in Philosophy of Science continues the linear time frame of modern physics. Future is happening after the present event. In the field of Futures Studies, people expect futurists to predict futures accurately. When futurists are predicting futures, and mapping possible futures, they employ Holism and Utopian thinking. Karl Propper opposed Historicism of trying to plan a blueprint for society.

中文摘要未来学萌芽於一九四○年代，从一九六○年到一九七○年未来学历经了科学哲学发展的巅峰时期，科学哲学的思想滋养了未来学家的思考，其中实证论、后实证论与批判实在论这三种论点影响了未来学家在时间概念上思考方向，科学哲学对时间概念的理解延续了现代物理时间观上线性式看待时间的方式，未来是当前事件必然发生的结果；在未来学的领域里，成功预测未来是大众对未来学者的期待，当未来学者在预测未来，进行未来规划时，思想中预含了整体主义与乌托邦式的思考，Propper从反对历史定论主义的思想来驳斥建立社会蓝图的可能。

Drawing on studies in intercultural communication, applied linguistics, pragmatics, sociolinguistics, discourse studies and other researches related to the studies of language, culture and communication, the author bases her ideology for interculturalizing ELT in China mainly on three lines of thinking: 1 the perception of language, communication and culture as triunity in language teaching and learning; 2 the understanding of the English teaching/learning process as dialogic interactions between the learner and the culture Other and between their pertaining linguacultures; 3 the rethinking of ELT in China as intercultural literacy education oriented towards intercultural speakership of the learner as a full-fledged member of the global community powered with intercultural communication competence in English.

本研究汲取了跨文化交际学、应用语言学、语用学、社会语言学、语篇分析及其他有关语言、文化和交际的研究成果，作者关于跨文化交际中国英语教学的思想主要建立在以下三个方面的认识：1语言、交际与文化在外语教学中应该被视为三位一体的统一体；2英语教学的过程是学习者与文化他者之间、以及他们各自相关的语言-文化之间对话性互动的过程；3中国英语教学应该是跨文化素质教育的重要组成部分和手段，其终极目标是把学生培养成为具有英语跨文化交际能力、在国际社会交往中运用自如、羽翼丰满的跨文化人。
