高分英语作文1：The Impact of Science and Technology on Education We may be surprised by the progress in every field of research, but it's extraordinary that the way to test a person's knowledge and ability is still as primitive as before. After all these years, educators still haven't designed a more effective and reliable method than the test, because they sincerely claim that the test tests what you know, which is common sense It may be a good way to test your memory or a knack for working quickly under extreme pressure. However, as a maker of anxiety, examinations can't tell you one's real abilities and talents. Examinations are second to none because they depend on examinations to a great extent. Examinations are a sign of success or failure in our society The future may be decided on a decisive day. From the moment a child starts to go to school, he enters a world of fiercecompetition.There are clear definitions and measures for success and failure. Can we be surprised at the increasing number of dropouts, young people who are considered to be total losers before they start working. Can we be surprised at the rate of students? A good education should, etc., train yourself to think about the examination system and do nothing, but what must be learned is strictly regulated by the syllabus.Therefore, encouraging students to recall examinations can not motivate students to read widely, but restrict their reading, which can not make them seek more knowledge, but induce cramming The most successful job seekers are not always the best educated. They are the best trained in the skills of working under pressure.中文翻译：我们也许会对每一个研究领域的进步感到惊讶，但是测试一个人的知识和能力的方法仍然像以前一样原始，真是太不寻常了，经过这么多年，教育家们仍然没有设计出比考试更有效、更可靠的方法，因为他们虔诚地宣称考试测试的是你所知道的东西，这是一个常识，即考试往往会适得其反，这可能是测试记忆力的好方法，或是在极端压力下快速工作的诀窍，但作为焦虑的制造者，考试并不能告诉你一个人真正的能力和才能，考试是首屈一指的，这是因为在很大程度上取决于考试，考试是我们社会成功或失败的标志，你的整个未来可能在一个决定性的日子里决定，从孩子开始上学的那一刻起，他进入了一个竞争激烈的世界，成功和失败都有明确的定义和衡量标准。

Telecommuting workers and traveling executives alike could use QB( so named because it is the next in line after the company’s prototype QA 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.3. Research had developed to the point where progress was being hampered by technical constraints, as the elegant experiments that had helped to decipher the genetic code could not be extended to investigate the gene in more detail.4. The ideas that the state of the universe at one time determines the state at all other times, has been a central tenet of science, ever since Laplace’s time.5.

Dark energy is the name given to an unexplained force that is drawing galaxies away from each other, against the pull of gravity, at an accelerated pace. Dark energy is a bit likeanti-gravity. Where gravity pulls things together at the more local level, dark energy tugs them apart on the grander scale. 2. The growth of membership and of individual networks seems impervious to gaffes at the company during its brief, five-year history.

Unit1 text A福岛的燕子我们对低剂量辐射对生物体和生态系统的影响知之甚少。

福岛核灾难四年后，科学家们开始得到一些答案。

By Steven Featherstone 直到1986年4月26日切洛贝利核电站的一个反应堆发生爆炸，在整个北半球扩散了相当于400枚广岛核弹的辐射尘，对于辐射对植被和野生动物的影响科学家几乎一无所知。

这场灾难创造了一个活生生的实验室，特别是在爆炸地点周围1100平方英里的地方，被称为禁区。

1994年，德克萨斯理工大学生物学教授罗纳德·切斯尔（Ronald Chesser）和罗伯特·贝克（Robert Baker）都是首批获准进入该区域的美国科学家。

我们抓到了一群田鼠，它们看起来像杂草一样健康。

贝克回忆说：“我们开始对它着迷。

当贝克和切斯对田鼠的DNA进行测序时，他们没有发现异常突变率。

他们还注意到，狼、猞猁和其他曾经稀有的物种在该区域游荡，仿佛它是一个原子野生动物保护区。

切洛贝利论坛由联合国一些机构于2003年成立，发表了一份关于切洛贝利利灾难20周年的报告，证实了这一观点，声称“环境改变对该地区的生物群产生了积极影响”，将其转变为“一个独特的生物多样性保护区”。

在Baker和Chesser对该地区进行田鼠研究的五年后，Timothy A.Mousseau 前往切洛贝利对鸟类进行了计数，发现了相互矛盾的证据。

南卡罗来纳大学生物学教授穆索和他的合作者现任巴黎南部大学生态，系统学与进化实验室的研究主任-- Anders Pape Moller，特别的研究了常见的乡村谷仓燕（Hirundo Rustica）。

他们发现该地区的燕子少得多，幸存下来的燕子寿命较短，生育力降低（男性），大脑较小，肿瘤，部分白化病（一种基因突变）和白内障发生率较高。

Mousseau 和Moller在过去13年发表的60多篇论文中表明，暴露于低水平辐射对该区域的整个生物圈（从微生物到哺乳动物，从虫子到鸟类）都有负面影响。

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.。

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。

科技英语阅读与翻译（李健）第二章设想一下:在一个新的产业诞生之际, 你目=睹见证了这一切! 这个产业是在前所未有的新技术基础上发展起来的, 其中包括一些实力雄厚企业销售的高度专业化商务设备, 还有越来越多的新兴公司生产的新奇玩具、为玩具藏家青睐的机巧装置, 以及其他一些奇特有趣的特殊产品。

但同时, 这还是一个缺乏行业标准和平台的、尚不成规模的产业。

项目复杂, 进步缓慢, 实际应用更是少之有少。

事实上, 尽管对这个产业的未来充满热情和希望,但是没有人能明确地说出什么时间- 或究竟是否有可能-它能取得关键性的规模发展。

但是,若真能实现发展, 那么,它很可能改变整个世界。

当然, 上述描述可算是上世纪70 年代中期计算机产业的写照, 也就在那时, 保罗·艾伦和我成立了微软公司。

当时,部分大企业、政府部门和其他一些机构都在使用笨重、昂贵的主计算机进行后台运算。

知名大学和大型工业实验室的研究人员正试图建造出最基本的构件, 以使信息化时代的到来成为可能。

当时英特尔公司刚刚推出他们的8080 微处理器,雅达利公司正在销售一款流行电子游戏“乒乓”。

而在国产计算机俱乐部里,爱好者急切地努力探索这种新技术带来的好处究竟是什么。

但当时我脑海中所萦绕的则是更具前瞻性的问题:机器人产业即将作为一项新兴的产业而崛起,其当时的发展同30 年前计算机的发展如出一辙。

想想看, 目前汽车组装线上使用的制造型机器人已替代了昔日的主计算机。

这个产业其他的典型产品包括可进行外科手术的机器手, 在伊拉克和阿富汗用于路边及地面排雷的侦察机器人, 以及可以进行地板吸尘的家用机器人。

电子产品公司还推出了可模仿人类、或是狗、恐龙等的机器人玩具, 而玩具收藏者们正迫不及待地想要猎取一套乐高公司生产的最新机器人系列玩具。

与此同时, 世界尖端科技人员正试图解决机器人技术中最棘手的难题, 诸如视觉识别、远程操控、以及学习型机器等问题, 而且他们正在不断获得成功。

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。

1.1苹果有一款新的热销产品，在欧美大部分地区已经卖到断货。

1.2如果你网上预定，六周后才能送达。

1.3一条网上评论写道，这是多年来最好的一款苹果产品。

1.4实用并且精巧的设计，使它拥有苹果产品史上最高的消费者满意度，根据creative strategies 和Experian两家公司的调查研究。

2.1如此的热情令苹果的老板们喜忧参半。

2.2我们今天讨论的这款产品是无线耳机airpods，看起来像苹果的传统耳机，只是没了数据线。

2.3定价在159美元，airpods可能是价值数十亿美元的一款商品。

像苹果手表，苹果于2015年开始销售的一种可穿戴设备。

2.4但是耳机并不是人们期待已久的具有改革能力的，极其具有利润的创新产品。

3.1在苹果最大的拳头产品推出后，这种等待并没有持续太久。

3.2在2007年6月29日，iPhone第一次开售。

3.3自此，苹果已经卖出了大约12亿部手机，并且取得了超过7400亿美元的销售额，从最畅销的科技设备可以看出。

3.4 2016年，苹果2160亿美元的销售额，其中三分之二来自于iPhone。

4.1登顶之后就是下山了。

4.2关于苹果的将来如何，苹果是否能设计出另一款与之相媲美的产品，这些问题一直困扰这苹果公司。

4.3持续增长的手机拥有率正在放缓，全球大约五分之二的人现在拥有一部手机。

4.4苹果也面临着更多的竞争，尤其是在中国（仅次于北美的第二大重要市场），其销量一直下滑，令人愈发担忧苹果正面临“苹果见顶”。

5.1即使苹果每年已经花费100亿美元用于研发，“人们并不指望能有所创新”，amit表示。

山东大学英语科技文献阅读翻译题一、阅读The Discovery of X-rays Except for a brief description of the Compton effect, and a few other remarks, we have postponed the discussion of X-rays until the present chapter because it is particularly convenient to treat X-ray spectra after treating optical spectra. Although this ordering may have given the reader a distorted impression of the historical importance of X-rays, this impression will be corrected shortly as we describe the crucial role played by X-rays in the development of modern physics.X-rays were discovered in 1895 by Roentgen while studying the phenomena of gaseous discharge. Using a cathode ray tube with a high voltage of several tens of kilovolts, he noticed that salts of barium would fluoresce when brought near the tube, although nothing visible was emitted by the tube. This effect persisted when the tube was wrapped with a layer of black cardboard. Roentgen soon established that the agency responsible for the fluorescence originated at the point at which the stream of energetic electrons struck the glass wall of the tube. Because of its unknown nature,he gave this agency the name X-rays. He found that X-rays could manifest themselves by darkening wrapped photographic plates, discharging charged electroscopes, as well as by causing fluorescence in a number of different substances. He also found that X-rays can penetrate considerable thicknesses of materials of low atomic number, whereas substances of high atomic number are relatively opaque. Roentgen took the first steps in identifying the nature of X-rays by using a system of slits to show that(1) they travel in straight lines, and that(2) they are uncharged, because they are not deflected by electric or magnetic fields.The discovery of X-rays aroused the interest of all physicists, and many joined in the investigation of their properties. In 1899 Haga and Wind performed a single slit diffraction experiment with X-rays which showed that (3)X-rays are a wave motion phenomenon, and, from the size of the diffraction pattern, their wavelength could be estimated to be 10-8 cm. In 1906 Barkla proved that(4) the waves are transverse by showing that they can be polarized by scattering from many materials.There is, of course, no longer anything unknown about the nature of X-rays. They are electromagnetic radiation of exactly the same nature as visible light, except that their wavelength is several orders of magnitude shorter. This conclusion follows from comparing properties 1 through 4 with the similar properties of visible light, but it was actually postulated by Thomson several years before all these properties were known.Thomson argued that X-rays are electromagnetic radiation because such radiation would be expected to be emitted from the point at which the electrons strike the wall of a cathode ray tube. At this point, the electrons suffer very violent accelerations in coming to a stop and, according to classical electromagnetic theory, all accelerated charged particles emit electromagnetic radiations. We shall see later that this explanation of the production of X-rays is at least partially correct.In common with other electromagnetic radiations,X-rays exhibit particle-like aspects as well as wave-like aspects. The reader will recall that the Compton effect, which is one of the most convincing demonstrations of the existence of quanta, wasoriginally observed with electromagnetic radiation in the X-ray region of wavelengths.Read the following text quickly and answer the questions.1.When were X-rays discovered?2.Who discovered them?3.What are the four characteristics of X-rays?答案：1.18952.Roentgen3.（1）.they travel in straight lines（2）.they are uncharged（3）.they are a wave motion phenomenon（4）.the waves are transverse二、翻译Translate the following passage into Chinese: When you are researching, write down every idea, fact, quotation, or paraphrase on a separate index card. Small(5"by 3") cards are easiest to work with. When you've collected all your cards, reshuffle them into the best possible order, and you have an outline, though you will undoubtedly want to reduce this outline to the essential points should you transcribe it to paper.A useful alternative involves using both white and coloured cards.When you come up with a point that you think may be one of the main points in your outline, write it at the top of a coloured card. Put each supporting note on a separate white card, using as much of the card as necessary. When you feel ready, arrange the coloured cards into a workable plan. Some of the points may not fit in. If so, either modify the plan or leave these points out. You may need to fill gaps by creating new cards.You can shuffle your supporting material into the plan by placing each of the white cards behind the point it helps support.答案：当你正在研究，写下每一个想法，事实上，报价，或意译在单独的索引卡。

核电与核辐射1986年4月26日，切尔诺贝利核电站的一个反应堆发生爆炸，将相当于400颗广岛原子弹的放射性尘降物散布到整个北半球。

在此之前，科学家对辐射对植物和野生动物的影响几乎一无所知。

这场灾难创造了一个活生生的实验室，尤其是在这个被称为禁区的1100平方英里的区域。

1994年，德州理工大学生物学教授罗纳德·切瑟和罗伯特·贝克是首批获准完全进入该区域的美国科学家之一。

“我们抓了一群田鼠，它们看起来和野草一样健康。

我们对此非常着迷。

”贝克回忆说。

当Baker和Chesser对田鼠的DNA进行测序时，他们没有发现异常的突变率。

他们还注意到狼、猞猁和其他曾经稀有的物种在这片区域游荡，仿佛这里是原子野生动物保护区。

2003年由一组联合国机构建立的切尔诺贝利论坛发表了声明一份关于灾难20周年的报告证实了这一观点，称“环境条件对该地区的生物群落产生了积极影响”，将其转变为“一个独特的生物多样性保护区”。

五年前，贝克和切塞尔在这片区域搜寻田鼠。

Mousseau到切尔诺贝利去数鸟，发现了与之相矛盾的证据。

穆萨乌是南卡罗莱纳大学的生物学教授，他的合作者安德斯·佩普·穆勒现在是巴黎南方大学生态、系统学和进化实验室的研究主任。

他们发现该地区家燕的数量要少得多，而那些存活下来的家燕则遭受着寿命缩短、(雄性)生育能力下降、大脑变小、肿瘤、部分白化病(一种基因突变)以及白内障发病率更高的痛苦。

在过去13年发表的60多篇论文中，Mousseau和Moller指出，暴露在低水平辐射下对该区域的整个生物圈产生了负面影响，从微生物到哺乳动物，从昆虫到鸟类。

包括贝克在内的批评人士对穆萨和穆勒持批评态度。

贝克在2006年与切塞尔合著的《美国科学家》(American Scientist)文章中指出，该区域“实际上已成为一个保护区”，穆萨和穆勒的“令人难以置信的结论只得到了间接证据的支持”。

我们所知道的关于电离辐射对健康影响的几乎所有信息都来自于一项正在进行的对原子弹幸存者的研究，该研究被称为寿命研究，简称LSS。

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 epochsof 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 vaporousby-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。
