论文写作常用句式
下面分享一下一些牛课题组论文撰写的基本程序：
1. 学生整理好实验数据；与导师讨论论文的基本构思、框架、插图；学生说明其实验结果的创新点；讨论决定投寄何种杂志。
2. 学生向导师提供与该课题有关的主要综述和研究论文（20～30篇）。
3. 由学生本人撰写论文初稿，送交导师。
4. 导师对初稿作出评论；请学生补充实验数据，并提出修改意见，但通常并不立即修改。
5. 参考导师评论和修改意见，学生撰写第二稿，送交导师。
6. 导师在第二稿基础上进行修改，部分内容完全重写，交回学生，请学生提出修改意见（用不同字体标明），形成第三稿。
7. 导师与学生对第三稿进行讨论后，由导师拟就第四稿，交回学生再评论和修改。
8. 对学生的评论和修改意见作认真考虑后，拟就第五稿（半定稿），请学生评论、修改，并对英文做仔细润色。
9. 导师最后定稿（第六稿），并对英文作仔细润色。
10. 由学生严格按投寄杂志的要求整理定稿、送审。
1. 前言部分
1.1 如何指出当前研究的不足以及有目的地引导出自己的研究的重要性
通常在叙述了前人成果之后，用However来引导不足，比如
However, little information...
little attention has been devoted to…
little work...
little data / little research
or few studies / investigations / few attempts have been don on…
or none of these studies
has (have) been less
done on ... / focused on / attempted to
conducted / investigated / studied
(with respect to)
OR To the author's knowledge... There is little information available in literature about...
Until recently, there is some lack of knowledge about...
Previous research (studies, records) has (have)
failed to consider
ignored
misinterpreted
neglected to
overestimated, underestimated
misleaded
thus, these previous results are
inconclusive / misleading…
unsatisfactory / questionable /controversial..
Uncertainties (discrepancies) still exist ...
一定要注意绝对不能全面否定前人的成果，即使在你看来前人的结论完全不对。这是前人工作最起码的尊重，英文叫做给别人的工作credits.
所以文章不要出现非常negative的评价，比如Their results are wrong, very questionable, have no commonsense, etc. 可以婉转地提出：
Their studies may be more reasonable if they had considered this situation.
Their results could be better convinced if they ...
Or Their conclusion may remain some uncertainties.
1.2.之后引导出一种新方法，或者一种新方向。
如果研究的方法以及方向和前人一样，可以通过下面的方式强调自己工作的作用：
However, data is still scarce
rare
less accurate
there is still dearth of
We need to / aim to / have to
provide more documents / data / records / studies
increase the dataset
Further studies are still necessary... / essential...
为了强调自己研究的重要性，一般还要在However之前介绍自己研究问题的反方面，另一方面等等, 比如：1)时间问题
如果你研究的问题时间上比较新，你就可以大量提及对时间较老的问题的研究及重要性，然后说(However)，对时间尺度比较新的问题研究不足
2)物性及研究手段问题
如果你要应用一种新手段或者研究方向，你可以提出当前比较流行的方法以及物质性质，然后说对你所研究的方向和方法，研究甚少。
3)研究区域问题
首先总结相邻区域或者其它区域的研究，然后强调这一区域研究不足
4)不确定性
虽然前人对这一问题研究很多，但是目前有两种或者更多种的观点，这种uncertanties, ambiguities，值得进一步澄清
5)提出自己的假设来验证
如果自己的研究完全是新的，没有前人的工作进行对比，在这种情况下，你可以自信地说，根据提出的过程，存在这种可能的结果，本文就是要证实这种结果。
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).
1.3. 如何提出自己的观点
We aim to…
This paper reports on…
provides results..
extends the method…
focus on..
The purpose of this paper is to..
Furthermore, Moreover, In addition,, we will also discuss...
1.4. 圈定自己的研究范围
前言的另外一个作用就是告诉读者包括(reviewer)你的文章主要研究内容。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，某种研究手段等等。为了减少这种争论，在前言的结尾你就要明确提出本文研究的范围：
1)时间尺度问题
如果你的问题涉及比较长的时序，你可以明确地提出本文只关心这一时间范围的问题。
We preliminarily focus on the older (younger)...
或者有两种时间尺度的问题(long-term and short term)，你可以说两者都重要，但是本文只涉及其中一种
2) 研究区域的问题
和时间问题一样，明确提出你只关心这一地区
1.5. 最后的原场
在前言的最后，还可以总结性地提出，这一研究对其它研究的帮助。
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。减少争论(arguments).
2. 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的置疑。
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)在更通常的情况下，由数据推断出一定的结论，
用，Results indicate, infer, suggest, imply that...
4) 在及其特别的情况才可以用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 (interpret this to..)
Or The results may be due to (caused by)/ attributed to / resulted from..
Or It seems that .. can account for (interpret) this..
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。
3. 连接词与逻辑
写英文论文最常见的一个毛病就是文章的逻辑不清楚。解决的方法有：
1)句子上下要有连贯，不能让句子之间独立
常见的连接词语有,
also, in addition, afterwards, moreover, Furthermore, further,
However, although, unlike, in contrast, Unfortunately,
Similarly, alternatively, parallel results, Compared with other results,
In order to, despite, For example
consequently, thus, therefore...
用好这些连接词，能够使观点表达得有层次，更加明确。
比如，如果叙述有时间顺序的事件或者文献，
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 (表明前面的观点错误，如果只是表明两种对立的观点，用in contrast)，BB.. 如果两种观点相近,可用
AA suggest ….. Similarly ( alternatively), BB..
Or Also, BB…
or BB also 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,
当写完一段英文，最好首先检查一下是否较好地应用了这些连接词。
2) 段落的整体逻辑
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。
首先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...
上面的例子可以清晰地把观点逐层叙述。
Or, 可以直接用First, Second, Third..... Finally,..
当然,Furthermore, in addition等可以用来补充说明。
4. 正文部份的整体结构
小标题是比较好的方法把要讨论的问题分为几个片段。
一般第一个片段指出文章最为重要的数据与结论。补充说明的部份可以放在最后一个片段。
一定要明白文章的读者会分为多个档次。文章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。
5. 关于abbreviation
如果文章用了很多的Abbreviation, 两种方法加以解决
1) 在文章最好加上个Appendix，把所有Abbreviation列表
2) 在不同的页面上，不时地给出Abbreviation的含义，用来提醒读者。
总之，写文章的目的是要让读者读懂，读得清晰，并且采取各种措施方便于读者。
5. Discussion 部分
5. 1时态
(a) 指出结果在哪些图表中列出，常用一般现在时。如：Figure 2 shows the variation in the temperature of the samples over time.
(b) 叙述或总结研究结果的内容为关于过去的事实，所以通常采用过去时。如：After flights of less than two hours, 11% of the army pilots and 33% of the civilian pilots reported back pain.
(c) 对研究结果进行说明或由其得出一般性推论时，多用现在时。如：The higher incidence of back pain in civilian pilots may be due to their greater accumulated flying time.
(d) 不同结果之间或实验数据与理论模型之间进行比较时，多采一般现在时（这种比较关系多为不受时间影响的逻辑上的事实）。如：These results agree well with the findings of Smith, et al.
6. 讨论部份包括什么内容?
6.1 主要内容
1) 主要数据特征的总结
2) 主要结论以及与前人观点的对比
3) 本文的不足
第三点，在一般作者看来不可取。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:
a) 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...
b) 结论有些不足
The results do not imply…
The results can not be used to determine…
be taken as evidence of…
Unfortunately, we can not determine thi s from this data…
Our results are lack of ...
但是，在指出这些不足之后，随后一定要再一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浮笔。
Notwithstanding its limitation, this study does suggest…
However, these problems could be solved if we consider…
Despite its prelimi nary character, this study can clearly indicate…
用中文来说，这一部份是左右逢源。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。但是，这些通过你的一些建议，这些问题在将来的研究中游可能实现。
P.S.
坚信观点的真实性：prove, demonstrate
不确定性：show，indicate，found
表示推测: imply，suggest
6．2 关于结论中的时态:
(1) 回顾研究目的时，通常使用过去时。如：In this study, the effects of two different learning methods were investigated.
(2) 如果所概述结果的有效性只是针对本次特定的研究，需用过去时；如果具有普遍的意义，则用现在时。如：In the first series of trials, the experimental values were all lower than the theoretical predictions. The experimental and theoretical values for the yields agree well.
(3) 阐述由结果得出的推论时，通常使用现在时。如：The data reported here suggest (These findings support the hypothesis, Our data provide evidence) that the reaction rate may be determined by the amount of oxygen available.
Some points of style
(摘自一个老外的Writing a Paper, 第一点和最后一点是我们经常用错的)
Do not use nouns as adjectives （不要把名词当作形容词用）
Not: ATP formation; reaction product
But: Formation of ATP; product of the reaction
The word “this” mu st always be followed by a noun, so that its reference is explicit.
（This 后面必须跟一个名词）
Not: This is a fast reaction; This leads us to conclude..,
But: This reaction is fast; This observation leads us to conclude…
Describe experimental results in the past tense. （试验结果用过去时）
Not: Addition of water gives product.
But: Addition of water gave product.
Use the active voice whenever possible. （尽可能使用主动语态）
Not: It was observed that the solution turned red.
But: The solution turned red.
OR We observed that the solution turned red.
Complete all comparisons. （使用完整的比较形式 A is higher than B）
Not: The yield was higher using bromine.
But: The yield was higher using bromine than chlorine.

Chapter 3. Proposed methodology
Assumption
l In the case when the assumption of a xx seems to be too restrictive or inadequate, the formulation with Fuzzy termination time, i.e. given by a fuzzy set in the space of control stages, may be applied.
l We assume here the fuzzy constraints to be state?dependent, and the fuzzy goal to be the same for all the control states, xx, which stems from the problem's nature.
l An approach to the solution of this problem is presented under the assumption that the sampling rate Decision can be made prior to the execution of the experiment, as opposed to being made while the experiment is in progress.
l Another assumption made above is that there are precise odds at which the expert is indifferent.
l Main simplifying assumptions are:
l This, in our view, is a questionable assumption.

l This is summarized in the following steps:
l Can be broadly classified into the following areas:
l Can be characterized by its function of effectively processing the

l The following steps should be followed
l xx can be classified by a different ways.
l Based on the xx, one may classify xx into the following:
l This catalog may change due to wear, breakage, and purchasing.
System
l Unlike many conventional program, expert systems do not usually deal wit
h problem for which there is clearly a right or wrong answer.
l The system consists of both ... and ...
l The system has a hierarchical modular architecture organized on three levels.
l expert system domains are area of expertise

l An interactive automatic ... system
l A .. is commonly thought of as a truly integrated .. system
l Should be capable of being generated from a ... system
l xx is an important part of the integrated system.
l The model consists of four rule bases, each of which addresses a separate problem in the hierarchy of
scheduling decision.
l The rule bases are linked to each other in a chin?like manner in the sense that the consequent of one rule base constitutes a part of the antecedent of the next rule base.
l The rule base consists of all possible combinations of the linguistic terms associated with the linguistic variable of the antecedent of a rule.
Computer System
l The system has been implemented using Prolog language in an MS?DOS environment. Prolog was chosen because it offers a well known and flexible environment in which fuzzy reasoning may be easily implemented.
l The current version of the xx program when compiled with WATFOR77 result
s in an executable code of about 270K bytes. Typical run time, when run on a
XX computer (an IBM compatible machine) operating at 4.77 Mhz with 640K RAM, ranges from 10 min to 2h, depending on the size (or complexity) of the problem.
l Time consuming procedures have been implemented in C?language and directly linked to the Prolog environment.
l The xx process, once the xx's data has been entered, requires approximately 180 seconds.
l It should be noted that the computation was done with a 20 Hhz, 80386
209;based microcomputer equipped with a 80387 math co?processor.
l The computer programs used for the analyses, one based on the xx method and the other based on the new method, were written in FORTRAN with a compiler that supports the math co?processor.
l Lisp, Prolog give maximum flexibility but also maximizes development time.
l Internal representation is the way a model is represented in the computer.
l An interactive menu-driven procedure is used in this study
l Shell can be develop very fast at the cost of time fairly severe limitations.
l While there is no measurable saving of time for the case involving five criteria, the saving is dramatic for the case involving 10 criteria -- the computation time reduces from 10 hr 40 min to about 1 min.
l This combination is being implemented in an objected?oriented programming environment (Smalltalk?80 system) to solve problems encountered in construction xxx.

l An algorithm based on the characteristic ... is used to determine
l Euler's formula states the following:
l The completed model should agree with the formula.
l For manufacturing purposes, a detailed and precise model of the object is necessary
l Engineering design models are very well defined; therefore,
l To keep the domain narrow enough to be implementable, yet wide enough to
be useful.
Point of View
l from an implementation standpoint,
l From the point of view of this application,
l From this point of view, Zadeh suggested an inference rule named xxx (CRI for short).
l Information is the meaningful interpretation and correlation of some aggregation of data in order to allow one to make decisions.
l From a practical point of view, the computational aspects of an FLC require a simplification of the fuzzy control algorithm.
l The use of a hammer to insert screws, although partly effective, tends to distort, destroy, and generally defeat the purpose of using a screw [Kusiak AI Implications for CIM p.129]
Justification
l We choose the so called xx in our experiment because it has received wide acceptance and can
l Prolog was chosen because it offers a well known and flexible environment in which fuzzy reasoning may be easily implemented.
l The rationale behind this is that it can be much easier for an estimator to rate a cost as high than to attempt to place a dollar value on the estimate.
l This strategy has been widely used in fuzzy control applications since it is natural and easy to implement.
l A function definition expresses the membership function of a fuzzy set in a functional form, typically a bell?shaped function, etc. Such functions are used in FLC because they lead themselves to manipulation through the use of fuzzy arithmetic.
l It should be noted that in our daily life most of the information on which our decisions are based is linguistic rather than numerical in nature. Seen in this perspective, fuzzy control rules provide a natural framework for the characterization of human behavior and decisions analysis.
l Many experts have found that fuzzy control rules provide a convenient way to express their domain knowledge. This explains why most FLCs are based on the knowledge and experience which are expressed in the language of fuzzy "if?the" rule.
Chapter 4. Examples
Example/ Data
l The data used in the following example was taken from an experiment in which xx was measured between x and x using a xx technique.
l The data consists of over xx measurements.
l An example of xx is discussed and the control rules of xx are compared with a xx
l Examples of complex processes to which this technique may be applied are xx, xx, etc.
l The following example is constructed only for the purpose of illustrating the computational procedure discussed.
l This example clearly demonstrates that the profile of an individual xx, or a very small group of xx, with no enough data to be studied statistically, can be meaningfully analyzed by fuzzy possibilistic methods.
l There is no space here to go into detail on all these methods, but deserve a mention and the bibliography will point to detailed references for those wishing this level of detail.
l Note that the golf ball spotting example is used throughout the paper.
Comparisons
l As well, the pros and cons of these representations from a process planning point of view will be discussed.
l The method of using xx to implement xx described by Zadeh (1973) appeared more suitable
l As discussed [in the previous section]/[preciously],
Relation
l We can not invert F' directly because it defines a many-to-one mapping.
l The relationships appear very complicate
l Lifting tasks involve complex and imprecise relationship between the task variables and the human operator's characteristics.
l These methods are based on the relationship between ... and ...
l The fundamental concept of a fuzzy rating language is that we can establish a relationship among terms such as high, medium, and low, and then modify these relationships.
l This article will thus mention the latter as well as the former.
l The former two bear a close relation to a fuzzy Cartesian product.
Importance
l The emphasis is on an implementation of a general approach to rule based decision making.
Consideration / Attention
l Careful evaluation is necessary to ensure
l Such a formulation does not change further considerations.
l Considerable attention has been paid to

l The xx system is versatile
l It has a very fast decision making process
l All the algorithms involve mostly logical operations.
l It can be easily and without additional cost implemented in a microprocessor?based environment.
l It can reduce the waste of designing from scratch.
l The advantages of using a xx to represent xx are the following:
l However, xx is not without its shortcomings.
l In most cases, the xxx shows an improvement over the existing xxx.
l Compared to the existing xx, the impacts of the xx are generally reduced by 5% to 9%.
l The "best case" results shows a savings of 6% to 9%.
l Most of the existing works based on xx approach can only recognize a xx .
l Most of the above methods are computational expansive and limited to xx.
l Some other advantages of xx are the following:
l The problem is the limitation of this method to a limited domain of parts.
l It proved limited in application because it demanded precision in system modeling that was impossible in practice.
l There are advantages to be gained in the structuring of costs and benefits, the use of xx,
l The disadvantages of this method are also disadvantages of conventional xx approaches.
l This combines the best features of both techniques
l Hopefully, this tool can be as the reference framework of for developing a xx platform, and helping the administration, marketing, and knowledge management activities in virtual communities.

l Their results may then serve as guidelines for lower level models, less fuzzy and more detailed.
Chapter 6. Conclusion
l From the discussion, one may conclude that ...
l Form the above discussion, the conclusion can be reached that

一．好的论文题目是成功的一半 好的论文，每一个部分都需要精雕细琢。我们先来看看Science, Nature 子刊上用的都是些什么题目，到底这些题目暗含哪些玄机以下是从2016年发表的论文中随机挑选的一些题目，我将其做了一下简单的分类： 1. Water splitting–biosynthetic system with CO2reduction efficiencies exceeding photosynthesis. (Science, 2016, 352, 1210) 类似: Scalable water splitting on particulate photocatalyst sheets with a solar-to-hydrogen energy conversion efficiency exceeding1%(Nature Materials 2016,15,611-615) 这种题目适合哪类文章适合于那种性能极其显着的文章（可以创纪录的文章），比如说Nocera et al. 的Science, 2016, 352, 1210，直接与光合作用进行对比，给人的震撼是非常强的。这种对比效果能够一下子抓住人们的眼球，吸引着读者进行阅读。 要点：使用这样的题目首先你的实验结果得够牛，你对于实验结果要足够自信，对于背景知识的了解得要足够深。因为取这样的题目意味着你要真正达到了某一个高度。如果明明有很多大海在那里，你个小池塘和小水坑进行比较，那么会闹笑话的。。。

文献综述参考范文
论《飘》中的现实主义 文献综述 引言 在20世纪的英美文学中，最具轰动效应的，莫过于美国女作家玛格丽特·米切尔（Margaret Mitchell,1900—1949）的长篇小说《飘》。该书自1936年问世以来，历经半个多世纪的考验，依然盛销不衰。小说以美国南北内战为背景，以战争的发展为线索，主要描写了女主人公斯嘉丽与维希礼和巴特勒之间的纠葛和恩怨。小说整体上是以女主人公斯嘉丽的爱情史为中心，虚写战争，实写战争对人类心灵的影响。此外，小说里还表现了对十九世纪中期美国南北文化的差异和矛盾，既是对当时南北战争中美国人的生活的生动刻画，也表现了当时战争中美国人勇敢和执着的精神。它是一部浪漫主义与现实主义创作手法相结合的优秀作品。尽管美国文坛一直有意贬低《飘》的文学价值,但它虽然未能进入文学经典的殿堂,却走进了千百万读者的心中。 一、国内对《飘》的相关评论 相对于西方而言，我国在《飘》的研究方面起步较晚，长期存在着接受与研究的严重脱节。即使是近年来这部小说获得越来越多的肯定评价，并正式进入文学史（以毛信德的《美国小说史纲》和王长荣的《现代美国小说》为代表），但对《飘》的研究也还是流于表面和简单。仅以中译本的序言水平就可见一斑：1990 年中国刮起了重译《飘》的旋风，一时出现沪本、京本、浙本三个版本的热闹场面，却没有一个本子的序言水平超过几十年前傅东华的译序。 《飘》作为一部富有争议的小说，吸引了许多文学工作者的目光。目前已有不少人从不同角度对《飘》进行了分析和欣赏。 张玉霞在《美国通俗小说经典〈飘〉研究综论》一文中认为，要对《飘》的持久魅力作出合理阐释，在整体的历史、文化的广阔视野关照下，必须回到细致的文本研究中去。张玉霞介绍了两个路径：1、把《飘》置于通俗文学发展进程中考察。从文类所属来看，它是历史小说与浪漫言情故事两个类型的交叉。偏重于形式要素的分析，得出的结论在于——优秀通俗小说的特征是“模式与模式突破”，即在内容和形式层面都具有承继、超越的双重性。而通俗小说的创作及接受两方面都受之影响。可以运用小说叙事学的研究方法进行具体的文本分析，并结合通俗小说类型研究来深入剖析《飘》的叙事结构特点。2、从创作流派及本土背景考察作为南方文学的《飘》，在解构与重建南方文化方面所具有的深刻内涵。 张淑英在《〈飘〉的流行与寂寞》一文中提到美国小说《飘》之所以能广泛流传的原因:一是艺术上的极高造诣,二是电影的推波助澜。然而,与小说的畅销和电影的火爆形成鲜明对照的是,一些文学史或文学手册中有关它的评论极少。很多人认为它是一部政治上反动的作品,这主要表现在小说对奴隶主和奴隶的阶级地位的描写,以及对南北战争有仇视情绪。 在王长荣的《现代美国小说史》中提到，《飘》是一部浪漫主义与现实主义创作手法相结合的优秀作品。他认为在人物塑造上，《飘》运用了浪漫主义的创作手法，女主人公斯嘉丽实际上成了表现南方神话的理想人物。从客观上讲，米切尔美化了正在崩溃的南方庄园经济，表现出对农奴主的同情。另一方面，在处理时代背景和人物对话时，米切尔却运用了现实主义的手法，使人读起《飘》来感到真切动人。
Summary的写作技巧和常见句型
S u m m a r y 的写作技巧和常见句型 、概括原文 一）阅读 1. 读懂文章读文章的时候，要养成良好的阅读习惯，划划写写，英文阅读的时候，用铅笔轻轻划出重点词汇。 认真阅读给定的原文材料。如果一遍不能理解，就多读两遍。阅读次数越多，你对原文的理解就越深刻。 2. 拆分文章按照作者的思路，把文章分段，每个段落用几个词，几个短语概括。尽量简短，精 炼。 段落中心句，在段落的开头或末尾。有时也会变态的在当中。 3. 概括主旨写出文章的thesis, 一句话概括文章的主旨。 二）基本结构和技巧 1.重新拟定标题给summary 起一个标题。用那些能概括文章主题思想的单词、短语或短句子作为标题。也可以采用文中的主题句作为标题。 2. 阐述观点 摘要应全部用自己的话完成。不要引用原文的句子。写概述的时候，如果能够明确是他人写作的文章，注意要把作者的名字放在第一句（或者是接着写出要阐述的main ideas （主要观点）和supporting points （对主要观点的the author .. ）。
支持）。 3. 词汇运用 注意概述的cohere nee （连贯性），运用好tran siti on words （过渡 词） , like however, furthermore, nonetheless, besides, therefore etc. 4. 删除细节 只保留主要观点。 5. 选择一至两个有代表性的例子 原文中可能包括5 个或更多的例子，你只需从中筛选一至二个例子。 6. 把长句变成短句，把长段的描述变成短小、简单的句子。 He was hard up for money and was being pressed by his creditor. 可以概括为：“ He was in finan cial difficulties. His courage in battle might without exaggeration be called lion- like. ” 可以概括为：” He was very brave in battle. He was hard up for money and was being pressed by his creditor. 可以概括为：“ He was in finan cial difficulties. 6）你还可以使用词组代替整句或者从句。请看下面的例子： Beautiful mountains like Mount Tai, Lushan Mountain, and Mount Huang, were visited by only a few people in the past. Today, better wages, holidays with pay, new hotels on these mountains, and better train and bus services, have brought them within reach of many who never thought of visiting them ten years ago. ” 可以概括为：” Beautiful mountains like Mount Tai, once visited by only a few people, are today accessible to many, thanks to better wages, paid holidays,

文献综述的撰写方法 文献综述是对某一方面的专题搜集大量情报资料后经综合分析而写成的一种学术论文，它是科学文献的一种。文献综述是反映当前某一领域中某分支学科或重要专题的最新进展、学术见解和建议的它往往能反映出有关问题的新动态、新趋势、新水平、新原理和新技术等等。写文献综述一般经过以下几个阶段：即选题，搜集阅读文献资料、拟定提纲（包括归纳、整理、分析）和成文。 一、选题和搜集阅读文献撰写文献综述通常出于某种需要，如为某学术会议的专题、从事某项科研、为某方面积累文献资料等等，所以，文献综述的选题，作者一般是明确的，不象科研课题选题那么困难。文献综述选题范围广，题目可大可小，大到一个领域、一个学科，小到一种疾病、一个方法、一个理论，可根据自己的需要而定，初次撰写文献综述，特别是实习同学所选题目宜小些，这样查阅文献的数量相对较小，撰写时易于归纳整理，否则，题目选得过大，查阅文献花费的时间太多，影响实习，而且归纳整理困难，最后写出的综述大题小作或是文不对题。选定题目后，则要围绕题目进行搜集与文题有关的文献。关于搜集文献的有关方法，前面的有关章节已经介绍，如看专著、年鉴法、浏览法、滚雪球法、检索法等等，在此不再重复。搜集文献要求越全越好，因而最常用的方法是用检索法。搜集好与文题有关的参考文献后，就要对这些参考文献进行阅读、归纳、整理，如何从这些文献中选出具有代表性、科学性和可靠性大的单篇研究文献十分重要，从某种意义上讲，所阅读和选择的文献的质量高低，直接影响文献综述的水平。因此在阅读文献时，要写好“读书笔记”、“读书心得”和做好“文献摘录卡片”。有自己的语言写下阅读时得到的启示、体会和想法，将文献的精髓摘录下来，不仅为撰写综述时提供有用的资料，而且对于训练自己的表达能力，阅读水平都有好处，特别是将文献整理成文献摘录卡片，对撰写综述极为有利。 二、格式与写法文献综述的格式与一般研究性论文的格式有所不同。这是因为研究性的论文注重研究的方法和结果，特别是阳性结果，而文献综述要求向读者介绍与主题有关的详细资料、动态、进展、展望以及对以上方面的评述。因此文献综述的格式相对多样，但总的来说，一般都包含以下四部分：即前言、主题、总结和参考文献。撰写文献综述时可按这四部分拟写提纲，在根据提纲进行撰写工。前言部分，主要是说明写作的目的，介绍有关的概念及定义以及综述
