毕业论文中英文摘要的主要内容
转眼间大学生活即将结束，大学毕业前都要通过最后的毕业论文，毕业论文是一种比较重要的检验学生学习成果的形式，那么你有了解过毕业论文吗？以下是我为大家收集的毕业论文中英文摘要的主要内容，希望能够帮助到大家。
1.摘要的作用
摘要也就是内容提要，是论文中不可缺少的一部分。论文摘要是一篇具有独立性的短文，有其特别的地方。它是建立在对论文进行总结的基础之上，用简单、明确、易懂、精辟的语言对全文内容加以概括，留主干去枝叶，提取论文的主要信息。作者的观点、论文的主要内容、研究成果、独到的见解，这些都应该在摘要中体现出来。好的摘要便于索引与查找，易于收录到大型资料库中并为他人提供信息。因此摘要在资料交流方面承担着至关重要的作用。
2.书写摘要的基本规范和原则
(1)论文摘要分为中文摘要和外文(一般为英文)摘要。摘要在篇幅方面的限定，不同的学校和机构有不同的要求，通常中文摘要不超过300字，英文摘要不超过250个实词，中英文摘要应一致。毕业论文摘要可适当增加篇幅。
(2)多向指导教师请教，并根据提供的意见及时修改，以期达到更高水平。
(3)摘要是完整的短文，具有独立性，可以单独使用。即使不看论文全文的内容，仍然可以理解论文的主要内容、作者的新观点和想法、课题所要实现的目的、采取的方法、研究的结果与结论。
(4)叙述完整，突出逻辑性，短文结构要合理。
(5)要求文字简明扼要，不容赘言，提取重要内容，不含前言、背景等细节部分，去掉旧结论、原始数据，不加评论和注释。采用直接表述的方法，删除不必要的文学修饰。摘要中不应包括作者将来的计划以及与此课题无关的内容，做到用最少的文字提供最大的信息量。
(6)摘要中不使用特殊字符，也不使用图表和化学结构式，以及由特殊字符组成的数学表达式，不列举例证。
3.摘要的四要素
目的、方法、结果和结论称为摘要的四要素。
(1)目的：指出研究的范围、目的、重要性、任务和前提条件，不是主题的简单重复。
(2)方法：简述课题的工作流程，研究了哪些主要内容，在这个过程中都做了哪些工作，包括对象、原理、条件、程序、手段等。
(3)结果：陈述研究之后重要的新发现、新成果及价值，包括通过调研、实验、观察取得的数据和结果，并剖析其不理想的局限部分。
(4)结论：通过对这个课题的研究所得出的重要结论，包括从中取得证实的正确观点，进行分析研究，比较预测其在实际生活中运用的意义，理论与实际相结合的价值。
4.撰写步骤
摘要作为一种特殊的陈述性短文，书写的步骤也与普通类型的文章有所不同。摘要的写作时间通常在论文的完成之后，但也可以采用提早写的方式，然后再边写论文边修改摘要。首先，从摘要的四要素出发，通读论文全文，仔细将文中的重要内容一一列出，特别是每段的主题句和论文结尾的归纳总结，保留梗概与精华部分，提取用于编写摘要的关键信息。然后，看这些信息能否完全、准确的回答摘要的四要素所涉及的问题，并要求语句精炼。若不足以回答这些问题，则重新阅读论文，摘录相应的内容进行补充。最后，将这些零散信息，组成符合语法规则和逻辑规则的完整句子，再进一步组成通畅的短文，通读此短文，反复修改，达到摘要的要求。
5.关于英文摘要
(1)英文摘要的写作方法要依据公认的写作规范。
(2)尽量使用简单句，避免句型单调，表达要求准确完整。
(3)正确使用冠词。
(4)使用标准英语书写，避免使用口语，应使用易于理解的常用词，不用生僻词汇。
(5)作者所做工作用过去时，结论用现在时。
(6)多使用主动语态。
6.关键词
关键词是为了文献标引工作从报告、论文中选出来用以表示全文主题内容信息目的单词术语。每篇报告、论文选取3~8个词作为关键词，以显着的字符另起一行，排在摘要的左方。如有可能，尽量用《汉语主题词表》等词表提供的'规范词。为了国际交流，应标注与中文对应的英文关键词。
关键词是主题词中的一类。主题词是一种新型检索词汇，多用于计算机网络检索。
关键词分为中文关键词和与之对应的英文关键词，分别置于中文摘要和英文摘要之下。为便于他人的检索，不能使用过于宽泛的词语。选择关键词既可以从论文的各级标题入手，也可以从论文本身的内容选取，将选出的关键词按照所涉及领域的范围从大到小顺序列出。
【论文摘要格式】
论文摘要是文章的内容不加诠释和评论的简短陈述。为了国际交流，还应有外文(多用英文)摘要。摘要是在文章全文完成之后提炼出来的，具有短、精、完整三大特点。摘要应具有独立性的自含性、即不阅读原文的全文.就能获得必要的信息。摘要中有数据、有结论、是一篇完整的短文.可以独立使用，也可以引用，还可以用于工艺推广。其内容应该包含与报告论文同等量的主要信息.以供读者确定有无必要阅读原论文全文，也可提供给文摘第二次文献采用。摘要一般应说明研究工作目的、实验方法、结果和最终结论等.而重点是结果和结论。中文摘要一般不宜超过300字，外文摘要不宜超过250个实词。除了实在迫不得已，摘要中不用图、表、化学结构式、非公知公用的符号和术语。摘要可用另页置于题名页(页上无正文)之前，学术论文的摘要一般置于题名和作者之后，论文正文之前。
论文摘要又称概要、内容提要。摘要是以提供文献内容梗概为目的，不加评论和补充解释，简明、确切地记述文献重要内容的短文。其基本要素包括研究目的、方法、结果和结论。具体地讲就是研究工作的主要对象和范围，采用的手段和方法，得出的结果和重要的结论，有时也包括具有情报价值的其它重要的信息。摘要应具有独立性和自明性，并且拥有与文献同等量的主要信息，即不阅读全文，就能获得必要的信息。摘要不容赘言,故需逐字推敲。内容必须完整、具体、使人一目了然。英文摘要虽以中文摘要为基础,但要考虑到不能阅读中文的读者的需求,实质性的内容不能遗漏。为此,我国的科技期刊近年来陆续采用结构式摘要,明确写出目的、方法、结果和结论四部分。
a.目的(Objective):简明指出此项工作的目的,研究的范围。
b.方法(Methods):简要说明研究课题的基本做法,包括对象(分组及每组例数、对照例数或动物只数等)、材料和方法(包括所用药品剂量,重复次数等)。统计方法特殊者需注明。
c.结果(Results):简要列出主要结果(需注明单位)、数据、统计学意义(P值)等,并说明其价值和局限性。
d.结论(Conclusion):简要说明从该项研究结果取得的正确观点、理论意义或实用价值、推广前景。
中、英文摘要前需标明中、英文文题，作者姓名(至多3名)及作者单位(邮政编码)。英文摘要应隔行打字,以便修改。

【论文题目】
机动车尾气污染防治对策与城市交通改善研究
【中文摘要】
本论文通过分析机动车尾气污染产生的原因，论述了采取多种防治对策以旨在减少机动车的尾气污染排放，同时对城市交通改善问题进行了深入的研究。本文首先论述了我国由于机动车尾气排放造成的城市大气污染的严重形势。论述了机动车尾气污染的产生原因。通过总结国内外机动车污染控制的发展历程、经验及教训，作者从两方面重点论述了控制机动车尾气污染的途径。其一是从机动车本身入手，在机动车生产、检验、维护保养以及采用新技术等方面对机动车加以改造，力争从尾气排放污染源加以控制;其次，作者根据我国交通的具体状况，详细分析了城市交通改善与机动车尾气排放的关系，根据翔实的数据：说明了在我国交通拥堵是造成机动车尾气污染的最主要原因。在科学交通管理的原则指导下，作者详细论述了科学交通管理的卞要措施，特别分析了对路口的交通控制策略的仿真优化过程，通过仿真结果表明，对路口的交通控制策略的优化将对尾气排放产生非常重大的影响，可以显著地减少污染排放总量。因此作者认为，科学交通管理是控制城市机动车尾气污染排放的根本出路。
正如个人页面所显示的那样，本人英语专业毕业，获英语专业八级证书，现从事英语文案工作。在校期间，曾参加过“外研社杯”全国英语写作大赛（浙江赛区）三等奖。说实话，这样的成绩并不令人骄傲，但过去的学术经历让我形成自己关于英语写作的一些心得和想法，此时此刻将它们整理出来，以大学生英语学习阶段较为常见的议论文和说明文为例，总结一些干货与你们分享。 【第一部分：议论文】 回想当年“外研社杯”全国英语写作大赛学校海选阶段，复赛名单出来之后老师与我们分享了他们当时改作文时的体验：许多同学的文章没有一个明确的框架结构，或者结构比较散落，影响了文章的质量。而所有进入复赛的同学，文章结构相对合理清晰，能够得到改卷老师的认可。可见，一个好的文章结构对于一篇文章来说尤为重要。 说实话，在很少背模板结构或句型的大前提下，我始终恪守着自己的议论文结构。在我看来，这样的结构赶紧利落，明确清晰，可适用于几乎所有的议论文，这个结构如下图。 那么就以“冰桶挑战”这个曾经的热门话题为例吧，之所以想选这个话题是因为不管是当年的写作比赛复赛试题还是专八考试的作文题，都以这个为背景出现。虽然具体题目有所差异，但本质还是不变的。简单来说，我们假设题目是Should Ice Bucket Challenge be Advocated? 在作答两份试题的时候，我均持否定意见，于是我的文章大概结构是这样的： Paragraph One： 描述冰桶挑战的背景。这里需要指出的是往往试题中会有一段文字介绍的就是相关背景，而部分学生往往不乐意自己思考而选择照搬照抄，这是写作的大忌。批卷的老师是绝对不会愿意给一个缺乏自己思考的学生以高分的。在这种情况下，必须要以自己的语言来进行描述，至少也是对于题目中已给背景作出paraphrase.此过程中需牢记一个原则：简明扼要。在第一段最后，提出自己的观点：From my perspective, the action of Ice Bucket Challenge should't be advocated. Paragraph Two： 第二段开头需要一句话来进行上下文的过渡，类似于：There are three reasons to support my point of view. / Three reasons will be provided in the following paragraphs to support my opinion.紧接着直截了当放上自己的第一个论据: In the first place, due to the reality that the physical conditions of different people vary, Ice Bucket Challenge can be a threat to some people's health. 接下来举相关的例子或理由来说明，比如某某某因为进行冰桶挑战而感冒了指出冰桶挑战并不值得提倡。 Paragraph Three/ Four: 三四两段的结构同第二段，只是不再需要过渡的语句可直接提出论据，比如：That some people tend to pay more attention to the stars who take the challenge and therefore ignore the real significance of the challenge is the second reason why I am not in favor of it./ To some extent, Ice Bucket Challenge is a waste of water, which servers as the third reason for my negative attitude towards Ice Bucket Challenge.然后同样，举出相关的例子或理由加以证明。 Paragraph Five: 进行对上文的总结，比如：Taking into consideration what has been mentioned above, I firmly hold that it is not wise to advocate Ice Bucket Challenge.总结往往要多于一句话，因此可以再次总结一下上文的内容以不一样的语言展现出来。但需要注意的是：结尾不应该出现新的话题和内容，因为往往新的内容没有经过论述或证明，缺乏说服性。 一篇好的文章，定是以丰富的词汇以及句型表达构成的。词汇部分，不一定要使用多么高级的表达，但尽量避免出现初高中生的高频单词，比如many，make me sad之类的，试着用新的词汇去代替那些烂大街的词。比如用“plenty of”"tons of"代替“many”，比如用“A sense of sorrow came to my mind when...”代替原来想要表达的“...make me sad.”以及还有最最经典的，用“an increasing number of”代替“more and more.” 句型部分，在涉及到议论文的时候，很频繁地会运用到“我认为...”“我的观点是...”，可怕的是，部分学生通篇文章下来，到处可见的只有"I think...",最多偶尔加个“I believe...”使得文章显得索然无味，其实，用以表达观点的句式并不少，只要稍微变换一下句型即可，比如：I hold the view that…； From my perspective,+内容; As far as I am concerned, +内容; My firm belief locates in that…等等。 此外，既然是formal writing，句式就不宜过于简单。过于重复的简单句叠加会让批卷的老师形成该学生英语水平不高的印象。适当使用从句、分句，简单句和复杂句交替使用，方能写成一篇好文章。 在已经具备良好结构和多样词汇句型的前提下，清晰的逻辑关系就显得尤为重要。在我看来，逻辑关系在议论文中主要体现在两个方面。一是提出的论据和论点的关系，二是论据与加以支持的例子和理由的关系。只有这两层逻辑关系清晰，论据能充分证明论点，理由和例子能完全支持论据，才能使自己笔下的这篇议论文站住脚。 【第二部分：说明文】 说明文和议论文在许多方面的要求可以通用，尤其是词汇和句型的多样表达。逻辑关系上，对于说明文的要求就在于整篇文章均能充分说明自己想要表达的话题即可。结构方面，我最提倡的说明文的结构还是总-分-总，做到收尾呼应。第一段简明扼要指出自己想要说明的事物/事情，第二到第四段从不同的方面加以说明，最后一段总结陈词。 以我当时写作比赛的说明文为例，题目要求大概是几位来自国外的同学来你校交换，请从不同方面介绍你的学校，并对他们表示欢迎。在文章的第一段，我就写明本篇文章的目的，不仅对于他们的到来表示了欢迎，同时指出在本篇文章中会简要介绍我们学校以便他们能更好地适应这里的生活。第二段到第四段，我分别从学习（课程，老师和同学），生活（宿舍条件，基本设备）以及课外活动三个方面加以论述，最后一段进行总结。最终的成绩告诉我，我的文章在一定程度上得到了认可。 英语写作水平的提高绝非是一朝一夕就能完成的事，需要持之以恒的积累和练习。在这里，想提出五点建议，相信对于写作水平的提高有所帮助。 英语写作考察的是formal writing.然而作为native language是中文的我们，很容易就写成了中式英语。多读英语原著，熟悉地道的英语表达会对英语写作有不少帮助。此外，说不定无意中记住的原著中的句子就成了自己英语文章中出彩的加分句，这也会是意外的收获。 无疑，英语语法的学习是枯燥和乏味的，但不可否认，如果一篇文章语法错误连篇，其他部分无论写的多么精彩也无法成为一名佳作。所以在平时的时候多翻翻语法书，把其当作是工具书，随时随地查漏补缺自己的语法漏洞，掌握正确的句型表达方法。 正如前面提到过的那样，出彩丰富的词汇和句型能为自己的文章增光添彩。所以无论是是平时课堂学习，还是做课外延伸阅读，需要培养自己记录佳词佳句的好习惯，然后把它们以合适的方式运用到自己的文章中。 现在大学生阶段的作文越来越与社会接轨，比如我在前面提到的“冰桶挑战”，就是某一个时间段的热点。尽管文章的要求里基本会涉及某事件的发生背景及主要概况，但是事先对于相关事件的知识储备无疑会增强我们写作的信心并提供有力的帮助，这就要求我们在平时保持关注时事热点的好习惯。 俗话说，“光说不练假把式，”勤于练习能帮助发现自己的不足，以明确今后自己努力方向。麻烦有经验的老师指正修改是提高自己写作水平的有效方式之一。通过老师的指导，我们能获得更多的灵感，拓宽自己的思维，从而取得更大的进步。 最后，愿每个努力的人都能被温柔以待，愿辛勤的汗水能浇灌出写作水平提升的花朵，也愿这篇文章能给予你哪怕一丝的灵感。
首字母应该大写。
英文文章中并没有”经济术语的每个首字母都一定要大写或第一个单词的首字母一定要大写“这样的硬性要求，通常有”专有名词“（例如：星球、国家、地区、城市、人等的名称，专业活动或奖项如世界杯、格莱美奖等）一般每个单词的首字母要大写的约定。
此外，在极端情况下，文章作者也可以在特别需要强调时，将一个单词或词组的所有字母都大写以示强调。例如“这不是我的错！”在特别需要强调“我”时，就可以写成That's not MY fault.（当然也可以说成That's not my fault at all.）
培养学生综合运用、巩固与扩展所学的基础理论和专业知识，培养学生独立分析、解决实际问题能力、培养学生处理数据和信息的能力。培养学生正确的理论联系实际的工作作风，严肃认真的科学态度。培养学生进行社会调查研究；文献资料收集、阅读和整理、使用；提出论点。
议论文的核心问题是逻辑论证,即以翔实的论据和严密的论证表明论点、阐述道理。我精心收集了英语议论文作文万能句子，供大家欣赏学习!

对于上述“十大句式”，具备以下显著特点：
1.“十大句式”具有普遍性。事实上，“十大句式”在阅读文章和写作范文中出现频率相当高，也是广大科研人员非常熟悉的句式。可以说，句句皆是万用的。一旦科研人员熟练地掌握了它们的用法，就能根据内容表达的需要，随时派上用场。用句夸张的话来说，就是“不怕写不到，就怕想不到”。
2.“十大句式”的提出基本符合最新科技论文写作评分标准中对句子结构的要求。“十大句式”中除了否定句、倒装句、插入语一般可以写成简单句以外，其它6到7句都属于复合句，占到总数的三分之二以上。换句话说，如果科研人员能运用十大句式正确地写出句子，那么不仅复杂句的数量就可以达到6到7分规定的要求，而且句式呈现多样化，复合句和简单句交错使用，以增强文章表达效果。
3. 增强科研人员句式的写作意识。“十大句式”对科研人员来讲，并不陌生，然而在写作考试中，由于时间紧迫，科研人员平时又缺乏运用已经掌握的句式的意识，因此多数科研人员以自己头脑中拼凑的中式英语取而代之，往往想不到运用这些句式。
4. 多数感觉句子写起来挥洒自如的科研人员，其中或多或少地在使用十大句式，在一定程度上说明他们头脑中已经培养起句式写作潜意识。
总之，句式变换直接影响到论文写作的成败。在此，衷心希望“十大句式”能为广大科技论文科研人员提供一条快速、高效的提高句式写作的途径，真正做到学以致用，“以不变应万变”

英语作文范文：年幼留学好不好
In recently, as people’s living standard improves, people start to pay attention on their kids. In our Chinese eyes, education is very important to develop kids. So, going to study abroad becomes more and more popular among young children. Some people think it is a good way to exercise the next generation, but some people consider it is not good for the study of the young kids. As far as I am concerned, I agree with the former opinion.
近年来，随着人们生活水平的提高，人们开始把重点放在孩子身上。在我们中国人眼里，教育对于培养孩子是非常重要的。所以，出国留学在小孩子中变得越来越受欢迎。一些人认为这是锻炼下一代的好方法，但有些人认为这并不利于孩子们的学习。就我而言，我同意前者的观点。
First of all, studying abroad is good to develop children’s independent ability. We all know that every child is the apple in their parents’ eyes. No matter the poor family or rich family, their parents will try their best to give the best things for their kids. There is no doubt that there will be little princess and prince appear. In such environment, how can the kids learn to be independent? However, the kids can get rid of their parents spoiling to go to study abroad. When they are in the foreign country, they have to do everything by themselves. How can’t they become independent?
首先，出国留学有助于培养孩子的独立能力。我们都知道每个孩子都是父母的掌上明珠。不管是贫穷的家庭还是有钱的家庭，他们的父母会尽他们最大的努力给孩子最好的。毫无疑问，出现小公主和小王子。在这样的环境中，小孩们如何学会独立呢?然而，出国留学孩子们可以摆脱父母的宠溺。当他们在国外时，所有的事情他们都要自己做。他们怎么可能不独立呢?
Secondly, different teaching method can improve the kids’ accept ability. The education in oversea is different from ours. If the kids can receive different education system, they must have better acceptance about everything in their life. Moreover, adapting various environments is good for to improve their adaptation. All this will lay a good foundation for their future.
其次，不同的教学方法可以提高学生们的接受能力。国外的教育与我们的不一样。如果孩子们能接受到不同的教育体系，对于他们生活的其他事情肯定会容易地接受。此外，适应各种环境有利于提高他们的适应能力。所有这一切都为他们自己的将来打下良好的基矗。
In a word, to study abroad in a young age is good for the development of children. They will benefit lots from it.
总之，年幼留学有利于孩子们的成长。他们会获益匪浅。
论文答辩用英语怎么说
五月到来，不少大四毕业生都面临着毕业前最后一道关卡——论文答辩。前期辛辛苦苦写了又改改了又写的论文，终于要到最后“判决”的阶段了。来看看毕业生们都关注的“论文答辩”英语该怎么说吧！
我们来看这句句子：
After all of the committee members have approved the thesis, the oral defense will be officially scheduled by the Graduate Office.
等到所有的委员会成员都通过了论文(审核)，研究生办公室将会安排正式的'答辩日期。
从上面的句子中我们可以看到，“论文答辩”就是“(thesis) oral defense”。有时候也会用“Viva-voce”来表示，但是多数情况下“Viva-voce”只针对博士生论文答辩。论文答辩委员会是“Thesis Defense Committee”。比如说“硕士论文答辩委员会”便是“Thesis Defense Committee for Master Degree”。
论文便是“thesis”，也有用“Dissertation”来表示论文的，但是一般来说，国外对于博士学位的论文才用“Dissertation”。其他学位学术论文都用“Thesis”。论文导师则是“Supervisor”。
