科技英语阅读教材ESTreadingunit4原文及译文高教出版Unite4 Electronic Information(robots)Remote-controlled Robot Surrogate Could Attend Your Next Meeting. for You(译文见下端)1It may look like a floor lamp mounted on a vacuum claener , but Anybots Inc.'s new QB is actually the latest in surrogate robotics . QB is designed to serve as your eyes ,ears and voice when you can't be there in person ,Even better , it's mobile , rolls around on two wheels like Rosie and can be navigated remotely via the Web and a Wi-Fi connection .2Telecommuting workers and traveling executives alike could us QB (so named because it is the next in line after the company's prototype QB bot) as a virtual extension of themselves. allowing them to attend meetings , tour facilities or perform walk-throughs of real estate properties , all while controlling the robot from a computer keyboard.3Anybots formally unveiled the remotely controlled robot on Tuesday and plans to start selling QBs by the end of the year .A five-megapixel vedio camera serves as one eye, whlie the other is a laser pointer. A speaker on the crown of QB's head gives it a mouthpiece, a touch-screen monitor on on its forehead enables software maintenance and other input , and a ring of protective rubber around its head makes it look a bit like Olivia Newton-John circa 1981.4Along with the wheels,a self-balancing system and a motor with a top speed of five kilometers per our make the robot mobile . The two-wheel-as opposed to a tricycle or quad-design makes it more maneuverable in tight spaces and helps keep its weight down to about 16 kilograms . The area between the QB'shead and base consists of a length of telescoping plastic that can be adjusted to let the QB stand as tall as 175 centimeters or as short as 81 centimeter.5Although it's unclear if the capacity for remote operation. willUS$15,000 Price tag .Anybots believe its technology will appeal to a new generation of workers who expect to be in contact at all times and in all places .The QB is designed to enable this connectivity without sacrificing “presence”,says Bob Christopher,president and chief operating officer of Anybots ,based in Moutain View,Calif . Bandwidth speed and vedio qu ality continue to improve , but they can’t replace being there , he adds .A test-drive reveals valuable Wi-Fi lesson6 To see how this might work in practice , Scientific American test-drove (from our editorial offices in New York) a QB located at Anybots’s facility in California . Our mossion was to drive across the building’s lobby and ask a second QB (remotely controlled by an Anybots employee) where we could find Erin Rapacki , who does product development for the company , and then proceed to Erin’s l ocation. The session began with logging on to a website set up by Anybots and selecting the IP address of the QB we were to inhabit.7 Once our robot “woke up” and connected to Anybots’s local Wi-Fi network, we used the arrow keys on our keyboard to navigate the QB across the lobby. The controls take some getting used to. Particularly because rugs and other materials on the floor may prevent the Qb from travelling a completely straight line . We easily found the other QB but had difficulty aligning our came ra so that we were staring directly into the other QB’s camera. This wasn’t necessary , because we could hearthe person controlling the other QB loud and clear through the microphone on our robot. Using the arrow keys,we were able to swivel our QB to the left and follow the relatively basic directions we had been given to our destination.8 With a bit more practice, navigation would have been smoother, THE QB features a buit-in lidar(light detection and ranging) system that warns the robot when it is getting too close to an object and slows the robot down to avoid(or at least reduce the impact of) a collision. The QB also has a camera located on the bottom of its “”chin” that points down at its wheels so you can see whether you’re about to drive over a lowe r obstacle(such as someone’s foot).9 The QB’s laser-pointer eye turned out to be useful when greeting people we encountered, including Anybots founder and CEO Trevor Blackwell, who accepted a laser beam in the palm of his hand in lieu of a handshake (a relief ,since the QB has no hands).10 By the time we were ready to leave , we were able to drive our QB back to the Anybots lobby and out the front door. Just past the building’s threshold, we learned a valuable lesson in surrogate navigation: never drive outside the range of your Wi-Fi network. A dropped connection means no cameras and no control over the robot’s navigation, which was especially unfortunate in our case because we were approaching the top ofa ramp down to the parking lot when we lost the signal.11 Danger,Will Robinson.Unit4译文今后远程控制的代理机器人可以为您参加的会议它可能看起来像装在一个真空吸尘器落地灯,但实际上它是Anybots公司最新的代理机器人的QB。

Unit 1搏弈论阿维纳什•迪克斯特&巴里•内尔巴夫搏弈是有关策略的科学。
它试图以数学和逻辑的方法来帮助搏弈者作出决策,在一系列纷繁复杂的搏弈中应采取何种策略来保证自己获得最大利益。
搏弈论研究的搏弈的范围包括了从下棋到抚育儿童,从网球竞技到公司转手。
但是所有的博弈都具有一个共同的特征:相互作用。
也就是说,每一个博弈者的博弈结果取决于所有博弈参与者的策略选择。
在零和搏弈中,搏弈者的利益之间是完全冲突的,因此一方的得利必然导致另一方的损失。
更多具有代表性的例子还有会导致共同得利(正和)搏弈和共同损失(负和)搏弈,同样的情况还会发生在另外一些冲突中。
搏弈论研究的先驱者是普林斯顿数学家约翰•冯•诺依曼。
在早先的一段时间里,研究的重点被放在了完全冲突(零和)搏弈(非合作搏弈)上,其他的搏弈当时被认为是以合作形式出现。
也就是说,搏弈要求参与者共同地选择和实施他们的行为.最近的研究则把重点放在了那些既不属于零和搏弈也不属于绝对合作搏弈的情况上,在这些搏弈中,搏弈者自主地选择搏弈行为,但他们之间的相互关系中充满了合作与竞争。
搏弈行为与我们在中性环境中所作的各种决定有着根本性的不同。
要说明这一点,我们可以思考一下伐木工人和军队将军所作决定之间的不同。
当伐木工人决定要如何砍树时,他不会考虑树木本身会有什么反抗,他所处的环境为中性。
而当将军决定要消灭敌军时,他必须提前预料到并消除敌军的反抗。
与这一例子中的将军相类似,一个搏弈者必须认识到他与其他机智且怀有争胜之心的竞争者之间的相互作用,他自己所作的决定也必须能够同时应对可能出现的合作或冲突。
搏弈的实质是搏弈者采取策略之间的相互依赖性。
这种策略性的相互依赖表现为两个不同的类别:连续策略之间的相互作用以及联立策略之间的相互作用。
就前者而言,搏弈者依次采取行动,每个人都会注意其他搏弈者先前的行为。
就后者而言,搏弈者同时采取行动,每个人都会忽略其他搏弈者当前的行为。
对连续策略博弈中的某一博弈这来说,一个普遍的原则就是放眼前方,及时反思和总结。

Unit 1 Genetically modified foods -- Feed the World?If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature.如果你想在某次晚宴上挑起一场激烈的争论,那就提出转基因食品的话题吧。
对许多人来说,高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。
特别是在有悠久的农业生产传统和主张环保的游说集团的国家里,转基因食品的主意似乎有悖自然。
In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle.事实上,转基因食品已经成为我们生活重要的一部分。

Unit 101 Something in the American psyche loves new frontiers. We hanker after wide-open spaces; we like to explore; we like to make rules but refuse to follow them. But in this age it’s hard to find a place where you can go and be yourself without worrying about the neighbors.美国人的内心深处具有一种酷爱探索新领域的气质。
我们渴求宽敞的场地,我们喜欢探索,喜欢制定规章制度,却不愿去遵守。
在当今时代,却很难找到一块空间,可以供你任意驰骋,又不必担心影响你的邻居。
02 There is such a place: cyberspace. Formerly a playground for computer fans, cyberspace now embraces every conceivable constituency: schoolchildren, flirtatious singles, Hungarian-Americans, accountants. Can they all get along? Or will our fear of kids surfing for dirty pictures behind their bedroom doors provoke a crackdown?确实有这样一个空间,那就是信息空间。
这里原本是计算机迷的游戏天地,但如今只要想像得到的各类人群应有尽有,包括少年儿童、轻佻的单身汉、美籍匈牙利人、会计等。
问题是他们都能和睦相处吗?人们是否会因为害怕孩子们躲在卧室里看网上的淫秽图片而将它封杀?03 The first order of business is to grasp what cyberspace is. It might help to leave behind metaphors of highways and frontiers and to think instead of real estate.2 Real estate, remember, is an intellectual, legal,artificial environment constructed on top of land. Real estate recognizes the difference between parkland and shopping mall, between red-light zone3 and school district, between church, state and drugstore.首先要解决的问题是,什么是信息空间。

科技英语阅读1-10单元译文:Unit 1罗素悖论的提出是基于这样的一个事例:设想有这样一群理发师,他们只给不给自己理发的人理发。
假设其中一个理发师符合上述的条件,不给自己理发;然而按照要求,他必须要给自己理发。
但是在这个集合中没有人会给自己理发。
(如果这样的话,这个理发师必定是给别人理发还要给自己理发)1901年,伯特兰·罗素悖论的发现打击了他其中的一个数学家同事。
在19世纪后期,弗雷格尝试发展一个基本原理以便数学上能使用符号逻辑。
他确立了形式表达式(如:x =2)和数学特性(如偶数)之间的联系。
按照弗雷格理论的发展,我们能自由的用一个特性去定义更多更深远的特性。
1903年,发表在《数学原理》上的罗素悖论从根本上揭示了弗雷格这种集合系统的局限性。
就现在而言,这种类型的集合系统能很好的用俗称集的结构式来描述。
例如,我们可以用x 代表整数,通过n来表示并且n大于3小于7,来表示4,5,6这样一个集合。
这种集合的书写形势就是:x={n:n是整数,3<n<7}。
集合中的对象并不一定是数字。
我们也可让y={x:x是美国的一个男性居民}。
表面上看,似乎任何一个关于x的描述都有一个符合要求的空间。
但是,罗素(和策梅洛一起)发现x={a:a不再a中}导致一个矛盾,就像对一群理发师的描述一样。
x它本身是在x的集合中吗?否定的答案导致了矛盾的出现。
当罗素发现了悖论,弗雷格立即就发现悖论对他的理论有致命的打击。
尽管这样,他还不能解决这个问题,并且上世纪有很多的尝试,去解决这个问题(但没有成功)。
罗素自己对这个悖论的回答促进了类型理论的形成。
他解释说,悖论的问题在于我们混淆了数集和数集的集合。
所以,罗素介绍了对象的分级系统:数、数集、数集的集合等等。
这个系统为形式化数学的形成奠定了基础,至今它还应用于哲学研究和计算机科学分支。
策梅洛对于罗素悖论的解决方法用新的公理:对于任意公式A(x)和任意集合b,都会有一个集合满足y={x:x既在b中又满足A(x)}取代了以前的公理:对于任意公式A(x),都会有一个集合满足y={x:x满足A(x)}。

Keys:第一章科技英语阅读第一节科技英语主要特点I.1.The first three sentences in Passage One are all constructed with passive voice while thefirst three sentences in Passage Two are constructed with active voice. Therefore, the language in Passage One sounds more formal and objective than that of Passage Two.2.The words spoken by Sheila in Passage Two are informal. Examples: "There's Ravi atthe home of that American doctor." (Contracted form); "A wonderful guy." (Incomplete sentence); "Ravi looks sweet, doesn 't he?" (Question tag).3.In the second paragraph of Passage One, "it" refers to "to use insecticide regularly, on avery large scale."4.In the second paragraph of Passage Two, "through" means "finish" or "complete."5.Passage One is written for academic purpose and Passage Two mainly for entertainment. II.Passage OneA blast of hot air is sent into the bottom of the furnace to make the coke burn fiercely. It is blown into the furnace through pipes. These pipes are installed around the circumference of the blast furnace eight feet above the bottom.While the coke is burning and iron is melting, gas is formed at the top of the chamber. This is led off from the top of the furnace to be used. It contains carbon monoxide, which is combustible. Part of this gas is used for making the air blast hot. It is led off into stoves.Passage TwoAll elements are composed of discrete units called atoms, which are the smallest particles that exhibit the characteristics of the element. Atoms are tiny units of matter composed of positively charged protons, negatively charged electrons, and electrically neutral neutrons. Protons and neutrons, which have approximately the same mass, are clustered in the nucleus in the center of the atom. Electrons, which are tiny in comparison to the other units, orbit the nucleus at high speed. Atoms that have an equal number of electrons and protons are electrically neutral. Those that have gained or lost electrons, and therefore are positively or negatively charged, are called ions.第二节科技、半科技英语专业术语I.1. D (自动驾驶仪)2. F (生物钟)3. I (热核的)4. G (地热的)5. B (微波)6. J (放射疗法)7.

section2--1-4科技英语阅读与翻译教程文件s e c t i o n2--1-4科技英语阅读与翻译1 Monograph专著1. The general definition of a monographScientific treatises of book length but otherwise variable format prepared by acknowledged experts onspecialized topics for the benefit of others who have specialized in. or who wish to obtain a specialist'sappreciation of, these topics.2. The value of monographs for scientific researchesThe value of monographs lies in the coherence and comprehensiveness of the information and knowledge they contain, which is important to the specialized researchers to whom they are directed and, therefore, to theadvancement of science and engineering generally.3. The qualities of the authors of monographsThe authors of monographs should have exceptional breadth and depth of knowledge, and must be able tocollect, collate, analyze, integrate, and synthesize all relevant contributions to the archival literature of thescientific and engineering journals and to add original material as required.4. The differences between monographs and books of conference proceedings Monographs generally are written by specialists for the benefit of other specialists. Textbooks are pedagogicalworks which, even if written on fairly narrow subjects, aredesigned to serve broader and more juniorreaderships than specialized research communities.5. The differences between monographs and books of conference proceedings Conference papers commonly take the form of premature announcements of new scientific discoveries.Conference proceedings generally have a short shelf life.6. The main components of a monographThe author, title and subtitle, date of publication, dust cover or blurb, content pages, bibliography and index,illustrations, preface and introduction.7. An indication of the book’s su ccessThe number of editions is an indication of the book’s success.8. The function of the blurbIt gives the reader a rapid overview of the contents and approach. It might also say what the book contains and for whom it is written.2 Academic Journal学术期刊1. The general definition of an academic journalAn academic journal is a peer-reviewed periodical in which scholarship relating to a particular academicdiscipline is published.2. The significance of peer-review processThe peer-review process is considered critical to establishinga reliable body of research and knowledge.3. The definition of review articlesReview articles, also called “reviews of progress”, are checks on the research published in journals.4. One difference between original research articles and review articlesUnlike original research articles, review articles tend to be solicited submissions, sometimes planned years inadvance.5. The places where science journals are authoritatively rankedNatural science journals are categorized and ranked in the Science Citation Index, and social science journalsin the Social Science Citation Index.6. The possible quantitative factors to reflect an academic journal’s prestigeThe number of later articles citing articles already published in the journal, the overall number of citations,how quickly articles are cited, and the average “half-life” of articles.7. The financial resources of humanities and social science academic journals Subsidies by universities or professional organizations and advertising fees by advertisers.8. The role of internet in the production of, and access to, academic journalsThe Internet has revolutionized the production of, and access to, academic journals, with their contentsavailable online via services subscribed to by academic libraries or even in a way of open access.33 Organization of a Scientific Paper科技论文的篇章结构1. In most scientific journals, scientific papers include the following sections Summary or Abstract, Introduction, Materials and Methods, Results, Discussion, Acknowledgments.2. The content of Summary or AbstractIt gives a brief background to the topic, describes conciselythe major findings of the paper, and relates thesefindings to the field of study.3. The Introduction section deals with the following two pointsIt describes first the accepted state of knowledge in a specialized field; then it focuses more specifically on a particular aspect, usually describing a finding or set of findings that led directly to the work described in the paper.4. The purpose of Materials and MethodsIts purpose is to describe the materials used in the experiments and the methods by which the experiments were carried out.5. The two ways of organizing ResultsIn some papers, the results are presented without extensive discussion, which is reserved for the followingsection. In other papers, results are given, and then they are interpreted, perhaps taken together with otherfindings not in the paper, so as to give the logical basis for later experiments.6. The purposes of the Discussion sectionThe data in the paper are interpreted; the findings of the paper are related to other findings in the field; thisserves to show how the findings contribute to knowledge, or correct the errors of previous work; some of thelogical arguments are often provided when it is necessary to clarify why later experiments were earned out.7. The reason for combining the Results and DiscussionBecause the data need extensive discussion to allow the reader to follow the train of logic developed in thecourse of the research.8. The difference between the abstracts in Science and those in NatureIn Science, the abstract is self-contained; in Nature, the abstract also serves as a brief introduction to the paper.4 Reading a Scientific Paper科技论文的阅读方法1. The order to understand the major points of the work, you should first read The Abstract.2. Reading the Title and the Abstract serves three purposesFirst, it clarifies whether you in fact know enough background to appreciate the paper. Second, it refreshes your memory about the topic. Third, it helps you integrate the new information into your previous knowledgeabout the topic.3. When reading in a familiar field, you can skim or even skipThe Introduction.4. The three typical codewordsData not shown, unpublished data, preliminary data.5. The poorly written papers are often related to three types of writersThose who are poor writers; those who do not enjoy writing, and do not take the time or effort to ensure thatthe prose is dear and logical; those who are so familiar with the material that it is difficult to step back and seeit from the point of view of a reader not familiar with the topic.6. The t hree characteristics of “bad writing”First, the logical connections are often left out. Second, papers are often cluttered with a great deal of jargon.Third, the authors often do not provide a clear roadmapthrough the paper.7. In better writing, the side issues are dealt with in the following waysThey are relegated to Figure legends or Materials and Methods or clearly identified as side issues, so as not to distract the reader.8.

Text AUnit2 The Future of Alternative Energy替代能源的前景Residential energy use in the United States will increase 25 percent by the year 2025, according to U.S. Department of Energy (DOE) forecasts. A small but increasing share of that extra power will trickle in from renewable sources like wind, sunlight, water and heat in the ground.美国能源部(DOE)预测,美国居民所使用的能源将在2025 年前增加25%。
增加的电能中将有一小部分来源于再生能源(如风、阳光、水、地热),而且这部分还会不断增大。
Last year alternative e nergy sources provided 6 percent of the nation’s energy supply, according to the DOE.美国能源部称,去年全国能源供应总量中有6%来自于替代能源。
“The future belongs to renewable energy,” said Brad Collins, the executive director of the American Solar Energy Society, a Boulder, Colorado-based nonprofit organization. “Scientist and industry experts may disagree over how long the world’s supply of oil and natural gas will last, but it will end,” Collin said.“未来属于再生能源,”美国太阳能协会执行主席布拉德·柯林斯说。

课文翻译21 10年之前当时在西澳大学的人类学家Nina Jalonski被要求做一项关于人类皮肤的演说。
作为灵长类进化研究的专家,她决定对肤色的进化史研讨一番,可是当她对课题进行文献研究时,结果却使她倍感失望。
在1970年之前的较为新的理论都存在种族主义,而另外的文献则相当缺乏说服力。
比如,有研究发表说白色皮肤可以更好的抵御寒冷。
1970年之后,研究人员渐渐认识到对于研究皮肤这样的课题变的无足轻重,因为这样的研究总是收获甚微。
Jalonski说:这个事实人人皆知,只是无人再议而已。
2 不久之后,Jablonski和她的丈夫Geoge Chaplin(一位地理信息系统专家)发表了第一份综合性肤色论。
该文章发表于人类进化日报中,该文章说明了肤色与全球光线强度之间存在强烈且可预测的关联。
但同时他们的发现也产生了一个深层次且令人吃惊的结论:肤色与维他命存在密切的联系。
3 作为加利福尼亚学术研究部门的领导,Jablonski首先假设我们最早的人类祖先有着与大猩猩(生物学角度最密切)类似的皮肤。
在450万年到200万年以前,早起人类从热带雨林中脱离,开始走向非洲东部大草原。
在以前的大草原上,人们不仅仅要更多的暴露于阳光下,而且他们忙于收集食物。
哺乳动物的大脑非常害怕过热,只需要5、6个级别的热量就能使他们中暑,因此我们祖先不得不发明更好的解暑办法。
4 答案很简单,那就是通过蒸发带走热量。
早起人类可能汗腺极少就像大猩猩一样,汗腺可能主要集中于他们的手掌中和脚底。
然而有时,某些个体会比通常的个体长更多汗腺。
这些汗腺更多的人,他们可以在热量驱逐他们躲在阴凉下之前有更长的时间去找食物。
因此他们能得到更多食物,使得他们能孕育更健康的后代,并且将发达的汗腺遗传给后代。
5 在几百万年的自然选择后,人类的身体上已经拥有大约200万个汗腺。
人类的皮肤相对于大猩猩的毛减少许多。
加利福尼亚大学的人类学家Adrienne Zihlaman 说:这样使得我们人类在沐浴后毛发干燥的更快。

s e c t i o n2--1-4科技英语阅读与翻译1 Monograph专著1. The general definition of a monographScientific treatises of book length but otherwise variable format prepared by acknowledged experts onspecialized topics for the benefit of others who have specialized in. or who wish to obtain a specialist'sappreciation of, these topics.2. The value of monographs for scientific researchesThe value of monographs lies in the coherence and comprehensiveness of the information and knowledge theycontain, which is important to the specialized researchers to whom they are directed and, therefore, to theadvancement of science and engineering generally.3. The qualities of the authors of monographsThe authors of monographs should have exceptional breadth and depth of knowledge, and must be able tocollect, collate, analyze, integrate, and synthesize all relevant contributions to the archival literature of thescientific and engineering journals and to add original material as required.4. The differences between monographs and books of conference proceedings Monographs generally are written by specialists for the benefit of other specialists. Textbooks are pedagogicalworks which, even if written on fairly narrow subjects, are designed to serve broader and more juniorreaderships than specialized research communities.5. The differences between monographs and books of conference proceedings Conference papers commonly take the form of premature announcements of new scientific discoveries.Conference proceedings generally have a short shelf life.6. The main components of a monographThe author, title and subtitle, date of publication, dust cover or blurb, content pages, bibliography and index,illustrations, preface and introduction.7. An indication of the book’s su ccessThe number of editions is an indication of the book’s success.8. The function of the blurbIt gives the reader a rapid overview of the contents and approach. It might also say what the book contains andfor whom it is written.2 Academic Journal学术期刊1. The general definition of an academic journalAn academic journal is a peer-reviewed periodical in which scholarship relating to a particular academicdiscipline is published.2. The significance of peer-review processThe peer-review process is considered critical to establishing a reliable body of research and knowledge.3. The definition of review articlesReview articles, also called “reviews of progress”, are checks on the research published in journals.4. One difference between original research articles and review articlesUnlike original research articles, review articles tend to be solicited submissions, sometimes planned years inadvance.5. The places where science journals are authoritatively rankedNatural science journals are categorized and ranked in the Science Citation Index, and social science journalsin the Social Science Citation Index.6. The possible quantitative factors to reflect an academic journal’s prestigeThe number of later articles citing articles already published in the journal, the overall number of citations,how quickly articles are cited, and the average “half-life” of articles.7. The financial resources of humanities and social science academic journals Subsidies by universities or professional organizations and advertising fees by advertisers.8. The role of internet in the production of, and access to, academic journalsThe Internet has revolutionized the production of, and access to, academic journals, with their contentsavailable online via services subscribed to by academic libraries or even in a way of open access.33 Organization of a Scientific Paper科技论文的篇章结构1. In most scientific journals, scientific papers include the following sections Summary or Abstract, Introduction, Materials and Methods, Results, Discussion, Acknowledgments.2. The content of Summary or AbstractIt gives a brief background to the topic, describes concisely the major findings of the paper, and relates thesefindings to the field of study.3. The Introduction section deals with the following two pointsIt describes first the accepted state of knowledge in a specialized field; then it focuses more specifically on aparticular aspect, usually describing a finding or set of findings that led directly to the work described in thepaper.4. The purpose of Materials and MethodsIts purpose is to describe the materials used in the experiments and the methods by which the experimentswere carried out.5. The two ways of organizing ResultsIn some papers, the results are presented without extensive discussion, which is reserved for the followingsection. In other papers, results are given, and then they are interpreted, perhaps taken together with otherfindings not in the paper, so as to give the logical basis for later experiments.6. The purposes of the Discussion sectionThe data in the paper are interpreted; the findings of the paper are related to other findings in the field; thisserves to show how the findings contribute to knowledge, or correct the errors of previous work; some of thelogical arguments are often provided when it is necessary to clarify why later experiments were earned out.7. The reason for combining the Results and DiscussionBecause the data need extensive discussion to allow the reader to follow the train of logic developed in thecourse of the research.8. The difference between the abstracts in Science and those in NatureIn Science, the abstract is self-contained; in Nature, the abstract also serves as a brief introduction to the paper.4 Reading a Scientific Paper科技论文的阅读方法1. The order to understand the major points of the work, you should first read The Abstract.2. Reading the Title and the Abstract serves three purposesFirst, it clarifies whether you in fact know enough background to appreciate the paper. Second, it refreshesyour memory about the topic. Third, it helps you integrate the new information into your previous knowledgeabout the topic.3. When reading in a familiar field, you can skim or even skipThe Introduction.4. The three typical codewordsData not shown, unpublished data, preliminary data.5. The poorly written papers are often related to three types of writersThose who are poor writers; those who do not enjoy writing, and do not take the time or effort to ensure thatthe prose is dear and logical; those who are so familiar with the material that it is difficult to step back and seeit from the point of view of a reader not familiar with the topic.6. The three characteristics of “bad writing”First, the logical connections are often left out. Second, papers are often cluttered with a great deal of jargon.Third, the authors often do not provide a clear roadmap through the paper.7. In better writing, the side issues are dealt with in the following waysThey are relegated to Figure legends or Materials and Methods or clearly identified as side issues, so as not todistract the reader.8. Another problem faced by the readers is that when they seek to understand just the experiment was,they may findThe authors refer back to previous papers; these refer in turn to previous papers m a long chain.。
