【编者按】虽然系统功能语言学(以下简称SFL)已经有近60年的发展史,但实际上SFL还有十分广阔的研究空间。原因有以下四点:第一、很多方面的研究欠缺,大量问题悬而未决。词汇层面的研究还很少,Halliday曾在多种场合呼吁加强词汇层面的研究,提出了词法(lexis)的概念。非主流语种,特别是少数族裔的语言的功能语言学研究几乎还是空白。语言资料不易获取的领域的研究还相当乏力,比如法庭庭审话语等。第二、层出不穷的语言现象令人目不暇接。口头语随着科技的发展正发生日新月异的变化。借助新媒介,尤其是网络技术,如今 Editor’s note Although SFL has a nearly 60-year history of development, SFL in fact has a very broad research space. The reasons are the following four points: First, many aspects of research lacking, a large number of issues pending. At the lexical level, there are few studies.
