1.引言
夜上海论坛 随着国内外学术交流的不断深入,对于学术论文写作和交流能力的要求也相应地提高。学术科研论文写作作为各种科研学术交流的主要形式已经成为学术交流的必备应用能力。学术论文具有高度的“规约性”,其属于赋有特定目的的交际事件类型,因此一般遵循约定俗成的惯例,而引言是学术论文的第一部分,具有可辨认的语步模式。根据Swales的观点,他采取“语步”(move)和“步骤”(step)来研究学术论文的引言,进而创建了CARS模式。CARS即 Create A Research Space,意为建立学术研究空间,这一模式表明学术论文引言作为一类体裁,体现了“建立学术研究空间”的交际目的。
基于体裁分析法的商务英语学术论文引言研究是本文关注的焦点,因为学术论文的引言部分对于整篇文章的构建具有提纲挈领的作用,通过引言的介绍,整个语篇的宏观结构及典型的交际目的便非常清晰,因此,就学术论文体裁的特征结合商务语言的特定交际目标,商务英语学术论文引言的体裁分析对这类文章的语用策略指导具有一定积极意义。本文基于体裁分析方法讨论商务英语学术论文引言的建构,以期能够挖掘商务英语学术论文引言语境的确定,模式的建立和语步分析的结构潜势。
2.相关研究综述
夜上海论坛 体裁分析理论最早是与文学研究密切相关的,之后由人种学家引入语言学领域(Swales,1990,p34)。经过二三十年的发展,而今,语言学家们就体裁概念的界定而言,有两个主要学派即:以斯维尔斯和巴蒂亚为代表的ESP学派(Swalesian ESP School)和以马丁为代表的澳大利亚学派(Australian School)。 John M.Swales的观点是“体裁是指包括具有共同交际目的的一组交际事件”(Swales,1990,p58);而深受韩礼德影响的澳大利亚学派则认为“体裁是一种有步骤,有目的的活动类型,其数量和社会行为的数量一致”。上世纪末,秦秀白教授对巴蒂亚的定义作过比较详尽的总结,包括以下4个方面:(1)体裁是一种可辨认的交际事件;(2)体裁是不一般的交际事件;(3)在建构语篇时,我们必须遵循某种特定体裁所要求的惯例;(4)尽管体裁有其惯例和制约性,内行人仍可在体裁的框架内传达个人的意图或交际目的。因此,我们可以看出各个学派在定义上存在差异,但本质是一致的:
(1) 体裁是对交际事件的一种分类;
(2) 交际事件的分类标准由语篇的内部结构特征和约定俗称的交际目的两个方面决定;
(3) 体裁具有常规性和制约性,语篇内容和形式需要遵循体裁要求;
(4) 同一体裁下的不同语篇存在差异。
夜上海论坛 ESP学派的代表人物斯维尔斯和巴蒂亚是把语步(move)和(step)作为语篇分析的出发点,以学术和职业语篇为分析对象,总结归纳出特定体裁的基本语步和步骤。例如:斯维尔斯(1990)总结了学术论文中引言,研究方法,结论各部分的话步和步骤,这就为高级写作和学术英语的教学等实际应用环境提供了一个理论框架。专门用途英语研究方法也都把体裁视为一种社会活动,认为体裁可能随着交际需要的变化而变化和发展。而本文所讨论的商务英语学术语篇也正是基于这一学派的理论框架进行分析与演绎,并借助语料库的思路预期这类型文章引言写作实践的谋篇布局。
3.研究设计
3.1 研究问题
本研究集中讨论商务英语学术语篇是否具有可辨认且固定的语步?这对同类型文章的引言写作有何意义?
夜上海论坛 3.2 研究方法及设计
众所周知,有关商务英语的学术期刊并不很多,事实上这在一定程度上也制约了这方面的研究,因此本文所分析的100篇文章主要从来源上分为2个部分:其中60篇选自于《中国ESP研究》,《商务外语研究》和《全国国际商务英语研讨会论文集》3类与商务英语专业密切相关的期刊及会议。目前,对外经济贸易大学在商务英语研究领域独占鳌头,由其主办的期刊可以被看作是国内这一学科发展最新,最全面且最专业的水平。而全国国际商务英语研讨会则是在商务英语学科不断发展前进的见证者,因此,选自于以上期刊及会议的60篇文章可以被视作发表于专业类期刊及会议的商务英语学术语篇,其余40篇选自于中国知网最新的以商务英语为题的学术论文。这些文章的选取旨在能够多渠道的采样文本,具备广泛性。本研究依据斯维尔斯的学术语篇引言分析的理论框架对所选取的篇章进行了语步分析及频率统计,并根据数据讨论给出了研究结果分析与说明。
4.结果与讨论
4.1语步分析
商务英语学术论文引言部分的体裁结构特征:
斯维尔斯的体裁理论为体裁分析提供了基本框架,并强调交际目的的关键作用。他首先着重研究了学术研究论文的引言部分,提出了“创建研究空间”分析模式,并对引言部分进行了语步分析:首先,建立研究范围;其次,建立研究地位;再次,占据研究地位。论文引言的语步模式、专业类期刊商英论文引言特征及专业类各语步统计频率分别如表1、表2、表3所示;表4、表5分别给出了非专业类期刊文章语步模式和非专业类各语步统计频率。
表1非常详细的列出了斯维尔斯关于学术论文引言语步的模式建构,共3个Move,每个语步下面细化为具体的步骤层次,但当这个语步分析应用到实际刊发的商务英语学术论文时就发现,这类文章的作者并不是严格按照语步顺序撰写文章,即使出现循环的步骤,只要满足写作需求都可以实行。这一点在下面语步统计的具体数据中得到了证实。表3专业类各语步统计频率中,例如摘自《中国ESP研究》中的文章,论文引言中虽然也出现了3个Move(语步),并且第一个Move中的3个Step与斯维尔斯的完全重合,但是当引言分析进行到第二个Move时,发现传统的学术论文引言中所包涵的4个步骤缩减为2个,第三个Move中的4个Step也只出现了其中2个。由此可见,学术论文的严谨逻辑是3个语步大框架所承载的,丰富的步骤推进会让文章的交际功能获得衔接链条的集约化,但是省略其中的一些具体步骤也并没有影响到语篇所应完成的交际目的,因而,对于专业类期刊中商务英语学术论文引言的分析可知,这部分写作的基本架构是3个宏观语步分别是Move 1:确定研究范围;Move 2:提出研究具体问题;Move 3:介绍自己在研究的具体问题上所作出的贡献(研究成果),当这3步确立之后,引言部分的语篇功能已经建立,具体步骤的参与例如表2,表3中的各个步骤实施顺序使得商务英语学术论文引言的这类交际事件类型完整而严密。这也说明,学术论文引言这类语言体裁,是有一定的,相对固定的典型的整体建构形式,体裁组织着功能语体,并且这些体裁不仅有语体的共性,还具有各自不同的语言使用特点和语言组织特点。从以上的表4和表5统计的频率可知,这些发表在中国知网非商务英语专业类期刊的学术论文的引言部分的Move1和Move3也基本符合斯维尔斯的提出的“创建研究空间”语步模式,但Move3中的step4在只有很少一部分文章直接在引言部分指出了文章的结构,这主要是由于各类期刊或文章篇幅的要求不一致,因为非专业类期刊所发表的商务英语学术语篇对文章引言的逻辑安排并不作要求,毕竟这些期刊所刊发的是各学科各门类文章,因而更加注重论文内容的创新及结论的时效性。另外,CARS模式的Move2中的:step1:对前人的研究成果提出质疑(Counter-claiming);step2:指处其不足之处(Indicating a gap)基本都没有出现在引言中,可见我国论文作者对Move2即提出研究的具体问题(Establishing a niche)这一步骤的写作习惯倾向于注重step3和step4的提出问题与继续研究这两个语步。总之在非商务英语专业类型的期刊上所发表的文章中,语步统计频率表基本呈现出了学术论文的引言步骤,但商务英语语篇的学术结合商务专业的特征并不明显,而且并未涉及CARS模式的全部步骤。但是Move1与Move3:确定研究范围(Establishing a territory)和 Move3 的概括研究目的(Occupying the Niche)的各个步骤基本在绝大多数的文章都得到了谋篇布局时的重点陈述。这证明了斯维尔斯的学术论文语步模式是广泛,通用及规约性的,它对商务英语学术论文引言的建构是有指导意义的,当然由于文章内容和交际目的的异同,当作者在应对不同的征稿意见及个人特定的写作习惯时,引言中的各个语步有所变动。就这点而言,无论是商务英语专业类抑或是非商务英语专业类期刊中的文章在引言写作中都没有差别。
5.结语
中国的贸易发展是有目共睹的,商务英语的学科建设是时展的客观要求。但只局限于模仿通用英语的教学与
夜上海论坛 研究方式是无法与现实的需求接轨的,因此,商务英语必须建立本学科实践特有的并且可循环的认知模式,而这就一定要在理论上得到基础层面的支持。商务英语学术科研的发展从根本上制约着此类人才的培养,商英学术论文正是承担这类科研的载体,本文所讨论的商务英语学术论文引言就是试图以体裁分析的方法探索这类新兴学科的学术论文的结构潜势,体裁的双重性即商务交际性及学术交际性使得这类特定的语篇在引言部分充分体现出了学术体裁的语步建构,全文的分析以期能够通过体裁的分析方式提高商英学术论文引言的框架指导,进而推动商务英语学术论文写作的更多的探究与研讨。
