本文主要是对比英汉语虚拟句的句法结构表现,从两大类——违背常理性和违背事实性虚拟句入手,旨在找出它们的相同点和相异点,并对其做适当的解析。此研究有助于多语对比的研究;此外,也对跨文化交际以及翻译的研究有所帮助,并进而对外语教学有一定的借鉴作用。 This article is mainly to compare the syntactic structure of English and Chinese virtual sentences. From two main categories - contrary to common sense and contrary to factual hypothetical sentences, we aim to find out the similarities and differences and make appropriate analysis . This research is helpful to the study of multilingualism. In addition, it is also helpful to the study of intercultural communication and translation, which in turn can provide reference for foreign language teaching.
