书写自己的生命华章

假如有人给你一支笔,一支密封的、纯色的水笔,里面有多少墨水你无法看到,很可能刚刚试着写几个字就能用干,也可能足够写一部或几部皇皇巨著,流传千古,使世事为之而改变。而这一切你在动笔之前无法知晓。

On the Nature and Role of English in Asia

The present paper is divided into eight sections:introduction,the global diffusion of English,perceptions of the new varieties,the issue of intelligibility,features that cause unintelligibility,need for a broader pragmatics,and pedagogical impli- cations,and conclusion,followed by the references.Not surprisingly,the global spread of English has generated varying perspec- tives on the nature and functions of its acculturated varieties.Broadly speaking,the debate has divided scholars into two camps holding diametrically opposing views on the multiple versions of English.On the one hand,some scholars view variations as symp- toms of linguistic degeneration and deterioration;on the other hand,some scholars legitimize them as inevitable manifestations ne- cessitated by the demands of the new cultural contexts.The normative view of the former camp stems,at least partly,from the problems the new forms of English pose in terms of international intelligibility.It is in this context that the paper examines the traditional,one-sided,native speaker-centred idea of intelligibility and the recent two-sided view of intelligibility that places the onus on both the native speaker and the non-native speaker.The argument of the latter camp is based on the premise that the new varieties require a broader pragmatic framework,because universal pragmatics is inadequate to describe them satisfactorily. Thus,the camp advocates a need for a language specific pragmatics,and a comparative pragmatics,in addition to the traditional universal pragmatics.Logically,the debate on phonological,lexical,grammatical,and discourse structure variations,and their le- gitimacy has prompted English language teaching specialists to have a fresh look at the goals and objectives of teaching English in the countries of the outer and expanding circles,and accordingly prioritize the teaching of national and regional varieties over that of the so-called native varieties.Thus,the paradigms of independence and centrality of the new varieties are replacing the paradigms of their dependence and marginality.
