我从Introduction的重要性、主要内容结构、中国学者常见写作误区和句型干货分享这四个方面来透彻聊聊Introduction引言部分。再次感谢我们工作室外籍老师整理的专业句型,本文内容全部摘自我的专栏文章,欢迎大家点击阅读:
中科院张老师:科研论文Introduction引言部分的作用中科院张老师:英文论文Introduction引言部分写什么?中科院张老师:英文论文Introduction写作误区和建议「一、什么是Introduction?」
初次接触科研论文写作的同学可能多少会有这样的疑问:
—— 到底什么是科研论文的Introduction引言呢?
—— 科研小白: "觉得它好像比Abstract摘要复杂详细一点?"
—— 好像又和后面的 Related Work (或者Literature Review) 文献综述有一些内容上的重叠?
「Introduction引言部分通过呈现研究课题所折射的研究理论来说服目标读者」。 引言部分不同于摘要Abstract), 字数上没有严格的局限性,但是内容方面要求在对应的选题上更加精准和明确(be concise and to the point)。引言通常需要承接摘要部分提出的几个学术方向展开话题,从比较宽泛的学术背景铺垫逐渐过渡到论文的研究课题(narrow down to the research problem)。
接下来我们通过一段小视频来进一步了我们写引言的目的:

看完了?们不妨透过下面两个问题来梳理一下其中信息:
Why An Introduction Is Needed?
「从文章的大结构来看Introduction提出了你的研究问题,这个问题的答案应该在文章的Discussion或者Conclusion部分呈现给读者,也就是在文章的首尾形成一个前后呼应的关系」。
那Introduction引言部分是只有一个横空出世的研究问题吗?
显然不是!引言部分需要解答两个核心问题:
1.研究空白是什么?为什么我们要填补这个研究空白?(更加接地气地表达就是, 你要说服读者这个研究空白很重要值得我们费时费力去探究)
2. 你的研究问题是什么?为什么你的研究问题可以填补这个研究空白?(更加接地气地表达就是,你要说服读者相信你的研究的确填补了这个领域的空白)
于是乎,整个引言部分的逻辑架构就呼之欲出了!
即我们的引言部分要清晰地呈现这样一个思路:
「二、那么具体到写作中应该包含哪些细节内容呢?」
我们通过这段视频来了解一下引言部分的结构:

「Introduction的行文框架可以理解为一个“漏斗结构”,也是一个从较宽泛的学术领域逐渐缩小到你的研究目标的过程」
接下来我们对于学术论文引言部分的几大内容一一展开详解:
Introduction引言部分的具体内容https://www.zhihu.com/video/1057983297900179456(Video Source: Youtube. By WORDVICE)
1. 研究背景和重要性(Background And Importance)
- Mention of previous work on the subject
- A statement of the importance of the subject
引言部分的第一段需要给出研究领域的大背景及其重要性所在。这个大背景勾勒出该领域科研成果从古至今的一个走向或者趋势 (what is known),为接下来本论文课题的发展生长提供温床。这部分内容的展开一定要引用该领域前人、大牛的经典文献或者奠基性著作,体现你对于该学科的一个总体把握是全面且客观的。那如何从这个大背景引入到论文的课题呢?当我们从该学术领域的大趋势逐渐缩小范围时,只需把其中「关联该论文课题的相关信息(keep stick to relevant information only)」拎出来说,这样才能保证最后能自然过渡到文章将要探讨的科研课题。
2. 引出该领域科研空白(What Is Unknown)
- Description of knowledge gap
摆出该研究领域的一个概况之后,就要顺理成章地指出哪些是我们还未涉及的领域(或是没有研究透彻的问题)。当然这样的问题有千千万万,此处不能全部罗列,必要要对应着你的论文课题来谈。直白地说,就是你论文课题研究的什么,此处就针对性地写“这个课题尚未被太多科研者涉足”云云。
3. 点题—指出本文的研究课题(Topic Of Research Paper)
- Announce the research topic/question being addressed in research paper
- How it will fill the missing brick in the wall of research already done
既然研究空白已近在眼前,那么对应的研究课题便要紧随其后。接下来就是你理直气壮陈述该论文主题的时刻,此时需要注意与研究空白的呼应,即在摆出课题是什么的基础之上更近一层,简要分析这个课题是「如何填补了科研空白」的。例如本文采用的模型预测精度更高?或是考虑了某个影响因子(前人研究没有考虑但是该因子其实很重要)的作用?亦或是在不同的实验条件、实验地点得出了和其他科研论文不一样的结论?
千万不要觉得这个关系显而易见嘛,为什么还要多写一句废话?殊不知这种 “进一步”的关联性分析往往是中国学生最喜欢忽略的,很多内容大家心里已经想到,唯独没有用英文去表述出来。
4. 概述文章的核心方法论和主要发现(Highlight The Approach And Principal Findings)
- Description of your approach and why you chose it (if needed)
- Brief summary of your major findings
这部分的内容并不是每一个学科领域或者所有期刊都有要求,但如果你的文章依照学科惯例要对这两方面提及的话,则可在Introduction的中简洁地做出概述。需要注意一定要提出主要的研究手段(是什么以及为什么选择它)和研究发现,不要过分展开更不需谈及细节,精炼地点到为止即可。
5. 提出猜想和研究目的(Hypothesis And Objectives)
最后在引言的结尾提出对之前科研问题的猜想以及你通过这项科研课题的研究想要达到的研究目的(Objectives)。研究目的可以依照文章的具体内容板块拆分成几个小点罗列出来。这种方式有点类似“节目预告”,给读者阅读后面的内容引路,一方面能够让读者明白后面内容的大致轮廓(Organization of this paper),另一方面也能抓住读者的注意力继续循着你提供的线索和方向探究下去。
「三. Introduction写作中需避免的常见错误」
在罗列写作误区之前先回答一个大家关注度讨论度很高的问题,那就是
什么时候写Introduction?(When to write Introduction)
什么时候写论文Introduction?https://www.zhihu.com/video/1057983833340772352(Video Source: Youtube. By WORDVICE)
正如上面的视频所陈述,在这里我们推荐理工科的论文写作中,把引言写作安排到「方法论(Methods)、结果(Results)和讨论(Discussion)部分完成之后,但是在结论(Conclusion)之前去开展写作」。这样的安排对于作者写作视角的搭建大有裨益,毕竟已经完成了文章的内容主体,相较于开始就写Introduction的做法,也更能精准呈现文章的信息。
那么接下来我们一一盘点写作中的常见误区吧!
论文Introduction常见写作误区https://www.zhihu.com/video/1058035416111931392(Video Source: Youtube. By WORDVICE)
「误区1」. 一个观点或者论据引用一大串文献 — Give too many citations for one point
例如Many studies have found a significant association between X and Y [4-15]. 这句话引用文献 [4-15] 实在是太多了,堆砌在一个观点的后面是审稿人很反感的。尽量节选重要的经典的或者最近的文献来引用。如果说这些文献实在是都很值得引用,那么不妨尝试改用下面的句式来展现A significant association has been found between X and Y in men[4-7], women [8-11], and children [12-15].
「误区2」. 指出研究课题不具体说明到底如何有研究价值 — Explain why your research topic is worth of study
例如我在修改学生论文时最常遇到的表达就是“… is important…”,但是没有给出细节描述重要性体现在哪些方面。所以如果你想说The development of new materials is important for the automotive industry, 则应该要这样去表述The development of new materials is necessaryfor the automotive industry to produce stronger, lighter vehicles, which will improve safety and fuel economy.(推荐表达,加粗部分具体指明在哪几个点体现新材料的重要性)
「误区3」. 细节过多导致句子不够精炼 — Bury your readers in detail
引言部分不要摆太多的细节和具体数据,尤其是关于论文研究结果的具体数据。关于研究方法、研究结果只需要概述性地在引言部分点到为止即可,接下来的章节会给它们更多的空间去展开更具体的内容。如果说引言部分所有论据和陈述都罗列太多细节性的内容,会让句子显得非常臃肿,导致干扰信息过多让读者抓不住重点。
例如 a previous study conducted in 2014 found that 10% fewer individuals were diagnosed with age-related diseases, such as arthritis, in areas with such healthcare policies in place.
推荐修改如下更精炼简洁 a previous study found that fewer individuals were diagnosed with age-related diseases in areas with such healthcare policies.
