科技英语阅读与翻译【牙齿仙女】Primitive peoples believe that hair, nail clippings, and lost teeth remain magically linked to the owner even after they have been disconnected from his body. As any voodoo artist will tell you, if you want to grind someone into powder, you don't need to touch him at all. It's quite enough to stamp on a missing molar and let ;contagious magic; do the rest. This is why peoples all over the world traditionally hide lost body parts, lest they fall into the wrong hands.远古时期的人们认为毛发、剪下的指甲和脱落的牙齿即使离开了人的身体,仍与其主人保持着神秘的联系。
正如任何一个伏都教大师都会告诉你的,假如你想置某人于死地,根本用不着去碰他,只需用脚踩碎那人脱落的一颗臼齿就够了,剩下的事就交给无边的法力去办。
这就是为什么全世界各个民族都习惯于把身体上脱落的东西藏起来,以免落入恶人之手。
American children's ritual of hiding lost teeth under their pillows probably derives distantly from this practice. But there is an obvious difference, for when Suzie conceals her baby milk-tooth, she fully expects it to be found, and by a good magician, not an evil one. Moreover, she expects to be paid for having surrendered it, and at the going rate. Nothing mare clearly suggests the blithe commercial gusto of our culture than this transformation of a fearful superstition into a cheery business transaction。

1 Hello. My name is Stephen Hawking. Physicist, cosmologist and something of a dreamer. Although I cannot move and I have to speak through a computer, in my mind I am free. Free to explore the universe and ask the big questions, such as: is time travel possible? Can we open a portal to the past or find a shortcut to the future? Can we ultimately use the laws of nature to become masters of time itself?大家好,我是斯蒂芬-霍金,是物理学家、宇宙学家及梦想家,尽管身体不能活动,只能通过电脑与大家交流,但从内心中我是自由的,自由地探索宇宙,思考以下重大问题:时间旅行是否可行?能否打开一个回到过去的通道,或找到通向未来的捷径?我们最终能否利用自然规律成为掌控时间的主人?2 To see how this might be possible, we need to look at time as physicists do - at the fourth dimension. It's not as hard as it sounds. Every attentive schoolchild knows that all physical objects, even me in my chair, exist in three dimensions. Everything has a width and a height and a length.为了让这一切从虚幻变成现实,我们应以物理学家的角度来重新审视时间——即第四维。

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 proceedingsMonographs 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 proceedingsConference 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 successThe number of editions is an indic ation 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 journalsSubsidies 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 sectionsSummary 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 thefollowingsection. 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 readThe 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.。

科技英语阅读与翻译全文Humanitarian Aid in SpaceSpace exploration technology will benefit developing countries in a variety of ways. Whether it's information about climate change or communication technologies that give remote areas access to the world outside, space science can come to the aid of vulnerable people in many countries.For the past two decades, Japan Aerospace Exploration Agency (JAXA) has been sending humanitarian aid dispatched from its space platform. This ambitious project has proved successful, and it’s been praised for its achievements in various aspects.The two strategic areas set forth for JAXA’s humanitarian aid effort are science and education. JAXA’s donations of books and puzzle sets are enabling elementary and junior high school kids in India to study science and math. There are plans to utilize remote sensing data to map out natural resources in Nepalese countryside and expand education related to environmental issues in Vietnam. In addition the agency is sending educational videos to the island nation of Palau tobetter understand their own local wildlife.JAXA is considered to be a pioneer in this area since the launch of their humanitarian aid initiative in 1997. The organization strives to make use of space applications for social welfare and reduce disparities in the world through a number of practical endeavors. The effort currently has a global reach, with projects taking place in seven continent, from Latin America to Africa.JAXA’s humanitarian aid programs will continue to grow with better technology and increased resources. The ongoing work reinforces the concept that space science and technology have the potential to contribute to enhancing the lives of people on Earth.人道主义援助在太空太空探索技术将在各个方面受益于发展中国家。

正在消失的计算机到2010年,我们将被计算机包围吗?是的,但我们却觉察不出来。
—比尔•盖茨(微软公司总裁和首席软件设计师)几年后,普通家庭娱乐系统可能与现在并没有太大的区别,但它很可能具有网络连接功能,用来下载和播放数字音乐和视频,在电视上显示艺术作品集和歌曲的名字,甚至收到重要邮件时打断正在播放的内容来提示你。
它将拥有一个中央处理器、磁盘存储器、制图硬件和某种直观的计算机用户界面。
如果再在加上一个无线鼠标和键盘,这个家庭娱乐系统看起来便很像是一台个人电脑。
人们会大量购买和使用这些系统吗?当然会。
他们会认为这种系统就是电脑吗?也许不会。
根据格特纳信息咨询公司(一家美国研究公司)的统计,世界计算机业在2002年销售了第10亿台个人电脑,而还有10亿台电脑预计在此后的6年中生产出来。
第一批的10亿台电脑几乎都是传统的台式机和笔记本电脑,但第二批的10亿台电脑将会明显不同,人们对它们进行了尽可能的完善,使它们能更好的按照人们的期望运作,例如便签大小的电脑,开会时我们可以用它来做笔记,或是躺在床上阅读电子邮件;娱乐型电脑,用来在客厅电视上播放音乐和电影;袖珍型电脑,用它无论在哪都能与他人保持联系。
除此之外,还有各种数量庞大的嵌入式计算机(如在手机、加油站和零售终端设备中使用的计算机),在功能和复杂性方面正迅速赶上台式电脑。
据估计,有意无意美国人每天会接触到大约150个嵌入式计算机系统。
这些系统使用了现在生产的90% %的微处理器,它们将不可避免地呈现出更多个人电脑的特点,而且能够与传统PC机进行无缝对接。
这一系统将无处不在。
根据半导体工业协会的调查,在2001年,世界芯片业为地球上的每位个男士人,女士妇女和儿童生产了大约6千万个晶体管,这一数字到2010年将上升为10亿。
与此同时,今天的多功能PC机将继续在大多数人的生活中发挥重要(而且是越来越重要)的作用,但其中心地位将体现在今天大部分人不认为是“电脑”的各类智能设备中。

第一单元自动化第二部分阅读A自动化的含义“自动化”已经是,而且现在仍然是,一个被大量滥用的词。
但是,人们对其确切的意义以及所包括的内容,正在逐渐地有了较为正确的了解。
如果不是下一个定义的话,我也许可以尝试作些解释,把自动化说成是一个概念。
运用这个概念,人们通过对机器装置的性能进行充分的测量、观察和控制,从而使其以最高的效率运转。
这需要对这种装置的功能有一个详细而连贯性的了解,以便需要时便能运用最佳的矫正操作。
自动化按其确切的意义,只有全面运用通信、计算和控制三个主要组成部分(“三C" )才能完全实现。
我认为,确保人们对合为一体的三个组成部分对我们的社会所蕴含着的某些意义有所认识和了解,是很有必要的。
首先,我们不妨考虑工业部门之一的炼钢工业。
在炼钢工业中,自动化已经开始成型。
到过钢厂的人都会知道从高炉开始的各种工艺流程的一些情况,成品条钢或板钢生产出来之后,再准备送往制造工艺车间或汽车厂,这些工艺流程是相互链接的。
为了使工厂中各个车间充分发挥效率,可以使用计算机来控制每个车间。
在此之前,计算机工作所需要的一切资料均输入机内。
就高炉来说,需要给计算机提供装人高炉的原料的信息、高炉工作温度的信息和处理各种各样配料的最好方法等方面的资料。
钢厂的高炉操作是一项复杂而要求技术熟练的作业,需要大量的知识和大量的综合信息,并迅速地做出判定选择,以便确保高炉工艺流程中的下一阶段的有效工作。
计算机对所有这一切都了解得很透彻,能够做出非常大量的中间判定,并且能够把全部信息立刻和不间断地提供给管理人员,以使他们做出高效管理这个工厂所需要的最后决定。
由此产生的信息数据和判定要进行处理,然后转送到下一个工序。
在这里,对操作的一些专门细节再次进行整理,提出最佳和最终的判定,然后对这些信息再一次进行处理并输送给下一道工序。
同时,当信息数据从生产单元的一道工序输送到下一工序并完全结合成为一项新的操作时,每次变化的结果反馈到最初阶段,而且,不断地做进一步的调整,结果是整个工厂的工艺流程便能够高效率地进行下去。
科技英语阅读与翻译(李健)---unit3 Dark nergy
As astronomers have explored this new phenomenon, they have found that, in addition to determining the overall expansion rate of the universe, dark energy has long-term consequences for smaller scales. As you zoom in from the entire observable universe, the first thing you notice is that matter on cosmic scales is distributed in a cobweblike pattern--a filigree of filaments, several tens of millions of light-years long, interspersed with voids of similar size. Simulations show that both matter and dark energy are needed to explain the pattern.
According to models, dark matter began to clump immediately after the big bang, forming spherical blobs that astronomers refer to as "halos." The baryons, in contrast, were initially kept from clumping by their interactions with one another and with radiation. They remained in a hot, gaseous phase. As the universe expanded, this gas cooled and the baryons were able to pack themselves together. The first stars and galaxies coalesced out of this cooled gas a few hundred million years after the big bang. They did not materialize in random locations but in the centers of the dark matter halos that had already taken shape.

(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)}。

Unit 3当所以人的朋友,是私人的事情吗脸谱网有一个重要的隐私人员,但是我怀疑他将从现在存在10年。
那不是因为脸谱不顾一切去掉隐私保护,但由于脸谱和其他社交网站的普及促进了共享个人的一切事物,消除了从公共分离出私事的结点。
由于共享的个人信息的范围扩展到,几个朋友一起归入脸谱的许多杂项的个人的“朋友”标签中,披露的事情成为很常态和私人的事情变得古怪和不合时宜。
脸谱的年轻成员,是那些高中生或者大学生,以及脸谱开始出现在校园里的时候那些舒适共享任何东西分应届毕业生。
它的老成员是仅仅在2006年打开网络工作场所后加入的。
任何人都调整到一个新的善于自我表达超过沉默的价值体系。
脸谱表示它有1.75亿会员,是世界上最大的社会网络。
但在美国,大多数成员都还比较年轻。
脸谱提供广告给5440万成员的目标,且不分年龄人人共享。
但是,如果广告客户想缩小它的目标观众到那些25岁或更老的,数量就会下降到2880万。
它缩小到30或以上岁数的人,脸谱只有仅仅提供2030万。
许多超过30 岁的人尚未注册,因此脸谱有一个惊人的增长机会。
每个星期,新成员是在美国以百万和全球范围会员和个人网络的增长,似乎不受公司在其短暂的五年历史的失态的影响。
其中的一个实例是在二月,当它与它的服务条款拨弄时。
新的语言似乎断言脸谱“不可撤销”的权利是去保留和使用一个成员的个人信息。
即使成员已经关闭了他或她的脸谱帐户,也应该多一点编辑。
这个强烈抗议是大声的,仅仅一些成员需要增加他们的声音去创建一个喧嚣声,然后脸谱恢复旧的语言。
几天后,它为公司和另一项权利和责任的草案,提供了一个草案原则,对将被批准的成员。
脸谱提供给成员很多隐私选项。
我算43个可以调整的设置,不包括一堆限制的、可以看出一个人的脸谱朋友安装软件应用程序的信息。
脸谱的默认设置是为在某些方面的新的帐户保护用户。
例如,在一个人的个人资料只限于朋友和其他人的学校,工作场所或地理网络。
它不是朋友的朋友访问。

Unlocking the Climate Puzzle解开气候之谜(1)Life has prospered on this planet for nearly four billion years. In that time, climate had fluctuated drastically, from ice ages lasting tens of thousands of years to epochs of steamy heat. With each change, sundry species have benefited and flourished.Others adapted, faltered, or died. Now, many experts believe, humans are imperiling their own ecological niche with the threat of global warming. The vaporous by-products of civilization, in the form of greenhouse gases such as carbon dioxide (C0₂), have trapped enough heat in the atmosphere to raise Earth's average surface air temperature a half degree Celsius (one degree Fahrenheit) during this century. If the trend continues, it could alter climate patterns worldwide-thawing glaciers, boosting sea level, scorching plains into deserts, and shifting vegetation zones.(1)生命在这个星球上已经发展了近四十亿年。

By far the most common genetically modified (GM) organisms are crop plants. But the technology has now been applied to almost all forms of life, from pets that glow under UV light to bacteria which form HIV- blocking "living condoms" and from pigs bearing spinach genes to goats that produce spider silk.到目前为止最常见的转基因生物体是农作物。
然而,这项技术现在已经应用于几乎所有形态的生命,从宠物在紫外线照射下发光到构成HIV-blocking 的“活的安全套”的细菌,从继承菠菜基因的猪到生产蜘蛛丝的山羊。
GM tomatoes, as puree, first appeared on British supermarket shelves in 1996 (a different fresh GM tomato first appeared in the US in 1994), but the consumer furore that surrounded GM technology did not erupt until February 1999.This was because a controversial study suggested that a few strains of GM potatoes might be toxic to laboratory rats.Those experiments, subsequently criticised by other experts, were carried out in Scotland by biochemist Arpad Pustzai.转基因西红柿酱, 在1996年第一次出现在英国的超市货架上(1994年不同的新鲜番茄在美国首次出现),但直到1999年2月消费者对基因技术的愤怒才爆发。

Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现:地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明,地球上的许多生态系统都达不到标准。
The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出,由于不可持续的使用,地球上将近三分之二的用来维持生命的生态系统(包括干净的水源、纯净的空气以及稳定的气候)正遭受破坏。
Human has caused much of this damage during the past half century. Soaring demand for food, fresh water, timber, fiber and fuel have led to dramatic environmental changes, from deforestation to chemical pollution, the report says. The already grim situation may worsen dramatically during the first half of the 21st century, the report’s authors warn.以上大部分的破坏都是人类在过去的半个世纪里造成的。

科技英语阅读李健课文翻译Thanksgiving Day 美国感恩节The American Thanksgiving is a holiday set aside each year in the United States to honor the blessings of the year and to offer thanks. It is one of the oldest holidays in America, having been celebrated since the time of the earliest settlers.每年美国都要为庆祝全年之恩与感激而定下例假,这就是美国人所庆祝的感恩节。
它是美国最古老的节日之一,早在最早的移民时期就开始庆祝了。
This holiday began when people first arrived at Plymouth colony in what we now call Massachusetts. They had sailed all the way to America onboard the Mayflower, a small and uncomfortable sailing ship. During their first winter, they were welcomed and helped by the Indians of the area. To celebrate their first successful harvest, they held a great feast.这个节日始于当时最早到达位于今麻省的普利茅斯殖民地的人们。
他们乘坐着一艘名叫“五月花号”的小而不舒服的帆船穿过了大海,抵达美洲。
第一个冬天里,当地的印第安人对他们表示欢迎和援助。
为庆祝第一次成功的丰收,他们举行了盛大的宴会。
At the time, many of the English settlers were earning aliving by farming and hunting, so the most common foods at the meal were fish, wild game, and local vegetables. The food was cooked over an open fire.当时,许多英国开始通过种植和捕猎来谋生,所以宴会上最常见的食物是鱼类、野味、当地的蔬菜,用火来烹饪。
