1.在普遍语法和语言类型学的背景上研究汉语话题 汉语研究应该置于世界语言变异的范围之中、在普遍语法和语言类型学的理论背景上展开,这一点现在已经成为越来越多的汉语研究者的共识。因为,只有这样,汉语研究的具体成果才能回馈于普通语言学理论;也只有这样,汉语语言学才能汇入世界语言学的主流。从这一点上看,徐烈炯、刘丹青(1998)《话题的结构与功能》可以说是比较充分地体现了汉语研究的共性意识以及对语法理论普遍性的追求。 1. The study of Chinese topics in the context of universal grammar and typology of language The study of Chinese should be placed within the scope of the linguistic variations of the world, expanding on the theoretical background of universal grammar and typology of languages, which has now become more and more Chinese researchers consensus. Because only in this way, the specific results of Chinese studies can be fed back to ordinary linguistic theory; the only way that Chinese linguistics can be imported into the mainstream of world linguistics. From this point of view, Xu Liejiong and Liu Danqing (1998) “The Structure and Function of Topics” can be more fully demonstrated the common sense of Chinese studies and the pursuit of universality of grammar theory.
