  二、英文写作的语言技巧

  1. Introduction:

  A. 如何指出当前研究的不足并有目的地引导出自己研究的重要性?在叙述前人成果之后,用However来引导不足,提出一种新方法或新方向。如:However, little information(little attention/little work/little data/little research……) (or few studies/few investigations/few researchers/few attempts……) (or no/none of these studies……) has (have) been done on (focused on/attempted to/conducted/investigated/studied(with respect to))。如:Previous research (studies, records) has (have) failed to consider/ ignored/ misinterpreted/ neglected to/overestimated, underestimated/misleaded. thus, these previous results are inconclisive, misleading, unsatisfactory, questionable, controversial. Uncertainties (discrepancies) still exist……研究方法和方向与前人一样时,可通过以下方式强调自己工作:However, data is still scarce(rare, less accurate),We need to(aim to, have to) provide more documents(data, records, studies, increase the dataset). Further studies are still necessary(essential)……

  强调自己研究的重要性,一般还要在However之前介绍与自己研究问题相反或相关的问题。比如:(1)时间问题;(2)研究手段问题;(3)研究区域问题;(4)不确定性;(5)提出自己的假设来验证。如果你研究的问题在时间上比较新,你可大量提及时间较老问题的研究及重要性,然后(However)表明“对时间尺度比较新的问题研究不足”;如果你的是一种新的研究手段或研究方向,你可提出当前流行的方法及其物质性质,然后(However)说对你所研究的方向方法研究甚少;如果研究涉及区域问题,就先总结相邻区域或其它区域的研究,然后(However)强调这一区域的研究不足;虽然前人对某一问题研究很多,但目前有两种或更多种观点,这种uncertainties或ambiguities值得进一步澄清;如果自己的研究是全是新的,没有前人的工作可对比,你就可以自信地说“根据假设提出的过程,存在这种可能的结果,本文就是要证实这种结果”等等。We aim to test the feasibility (reliability) of the……It is hoped that the question will be resolved (fall away) with our proposed method (approach).

  B. 提出自己的观点:We aim to//This paper reports on//This paper provides results//This paper extends the method//This paper focus on……The purpose of this paper is to……Furthermore, Moreover, In addition, we will also discuss……

  C. 圈定自己的研究范围:introduction的另一个作用就是告诉读者(包括reviewer),你文章的主要研究内容。如果处理不好,reviewer会提出严厉的建议,比如你没有考虑某种可能性,某种研究手段等。为减少这种争论,在前言的结尾就必须明确提出本文研究的范围:(1)时间尺度;(2) 研究区域等。如涉及较长的时序,你可明确提出本文只关心某一特定时间范围的问题,We preliminarily focus on the older (younger)……如有两种时间尺度 (long-term and short term),你可说两者都重要,但是本文只涉及其中一种。研究区域的问题,和时间问题一样,也需明确提出你只关心某一特定区域!

  D. 最后的圆场:在前言的最后,还可以总结性地提出“这一研究对其它研究有什么帮助”;或者说further studies on……will be summarized in our next study (or elsewhere)。总之,其目的就是让读者把思路集中到你要讨论的问题上来。尽量减少不必要的争论(arguments)。

  2. Discussion:

  A. 怎样提出观点:在提出自己的观点时,采取什么样的策略很重要,不合适的句子通常会遭到reviewer置疑。(1)如果观点不是这篇文章最新提出的,通常要用We confirm that……(2)对于自己很自信的观点,可用We believe that……(3)通常,由数据推断出一定的结论,用Results indicate, infer, suggest, imply that……(4) 在极其特别时才可用We put forward(discover, observe)……"for the first time"来强调自己的创新……(5) 如果自己对所提出的观点不完全肯定,可用We tentatively put forward (interrprete this to…)Or The results may be due to (caused by) attributed to resulted from……Or This is probably a consequence of……It seems that……can account for (interpret) this……Or It is posible that it stem from……要注意这些结构要合理搭配。如果通篇是类型1)和5),那这篇文章的意义就大打折扣。如果全是2),肯定会遭到置疑。所以要仔细分析自己成果的创新性以及可信度。

  B. 连接词与逻辑:写英文论文最常见的毛病是文章的逻辑不清楚,解决方法如下。

  (1) 注意句子上下连贯,不能让句子独立。常见的连接词有,However, also, in addition, consequently, afterwards, moreover, Furthermore, further, although, unlike, in contrast, Similarly, Unfortunately, alternatively, parallel results, In order to, despite, For example, Compared with, other results, thus, therefore……用好连接词能使文章层次清楚,意思明确。比如,叙述有时间顺序的事件或文献,最早的文献可用AA advocated it for the first time.接下来可用Then BB further demonstrated that. 再接下来,可用Afterwards, CC……如果还有,可用More recent studies by DD……如果叙述两种观点,要把它们截然分开AA put forward that……In contrast, BB believe or Unlike AA, BB suggest or On the contrary (表明前面观点错误),如果只表明两种观点对立,用in contrast BB……如果两种观点相近,可用AA suggest……Similarily, alternatively, BB……Or Also, BB or BB allso does……表示因果或者前后关系可用Consequently, therefore, as a result……表明递进关系可用furthermore, further, moreover, in addition……写完一段英文,最好首先检查是否较好地应用了这些连接词。

  (2) 注意段落布局的整体逻辑:经常我们要叙述一个问题的几个方面。这种情况下,一定要注意逻辑结构。第一段要明确告诉读者你要讨论几个部份……Therefore, there are three aspects of this problem have to be addressed. The first question involves……The second problem relates to……The third aspect deals with……清晰地把观点逐层叙述。也可以直接用First, Second, Third, Finally……当然,Furthermore, in addition等可以用来补充说明。

  (3) 讨论部份的整体结构:小标题是把问题分为几个片段的好方法。通常第一个片段指出文章最重要的数据或结果;补充说明部份放在最后一个片段。一定要明白,文章的读者分为多个档次;除了本专业的专业人士读懂以外,一定要想办法能让更多的外专业人读懂。所以可以把讨论部份分为两部份,一部份提出观点,另一部份详细介绍过程以及论述的依据。这样专业外的人士可以了解文章的主要观点,比较专业的讨论他可以把它当成黑箱子,而这一部份本专业人士可以进一步研究。

  C.讨论部分包括什么内容?(1)主要数据及其特征的总结;(2)主要结论及与前人观点的对比;(3) 本文的不足。对第三点,一般作者看来不可取,但事实上给出文章的不足恰恰是保护自己文章的重要手段。如果刻意隐藏文章的漏洞,觉得别人看不出来,是非常不明智的。所谓不足,包括以下内容:(1)研究的问题有点片面,讨论时一定要说,It should be noted that this study has examined only……We concentrate (focus) on only……We have to point out that we do not……Some limitations of this study are……(2)结论有些不足,The results do not imply……The results can not be used to determine(or be taken as evidence of)……Unfortunately, we can not determine this from this data……Our results are lack of……但指出这些不足之后,一定要马上再次加强本文的重要性以及可能采取的手段来解决这些不足,为别人或者自己的下一步研究打下伏笔。Not withstanding its limitation, this study does suggest……However, these problems could be solved if we consider……Despite its preliminary character, this study can clearly indicate……用中文来说这是左右逢源,把审稿人想到的问题提前给一个交代,同时表明你已经在思考这些问题,但是由于文章长度,试验进度或者试验手段的制约,暂时不能回答这些问题。但通过你的一些建议,这些问题在将来的研究中有可能实现。
