计算机是最伟大的发明英文作文
计算机是最伟大的发明英文作文In the pantheon of human invention, the computer stands as a titan, reshaping every facet of our lives with its digital alchemy. From the abacus to the smartphone, the journey of computing devices has been nothing short of miraculous, a testament to human ingenuity and the relentless pursuit of progress.The computer's inception can be traced back to the need for complex calculations, far beyond the capability of human mental arithmetic. Charles Babbage's Analytical Engine, conceptualized in the 19th century, laid the groundwork for what would become the modern computer. It was an idea ahead of its time, envisioning a machine that could perform a variety of calculations through a series of mechanical instructions.As the 20th century dawned, the evolution of computers accelerated. The colossal ENIAC, developed in the 1940s, became the herald of the electronic age. It was a behemoth, consuming vast amounts of power and space, yet it unlocked new possibilities in computation, science, and engineering.The true revolution, however, began with the miniaturization of electronic components. The invention of the transistor and later the integrated circuit paved the way for computers to become accessible to the masses. The 1980s saw the advent of personal computers, bringing the transformative power of computing into homes and offices around the world.The impact of computers on society is immeasurable. They have become the backbone of modern infrastructure, controlling everything from traffic lights to financial markets. In science, computers enable simulations of complex phenomena, from the behavior of subatomic particles to the formation of galaxies. In medicine, they assist in diagnosing diseases and modeling biological processes.Perhaps the most profound change has been in communication. The Internet, a global network of computers, has connected humanity in ways previously unimaginable. It has democratized information, fostered global communities, and given rise to new industriesand careers. Social media, a byproduct of the Internet, has altered the landscape of human interaction, for better or worse.The computer has also been a catalyst for creativity. Digital art, music production, and film-making have evolved with the tools provided by computing technology. Writers, artists, and musicians harness software to push the boundaries of their crafts, creating works that blend traditional techniques with digital innovation.In education, computers have opened doors to knowledge that were once closed to many. Online courses and resources have made learning more accessible, breaking down barriers of geography and socioeconomic status. Students can explore subjects in virtual environments, engage with interactive modules, and collaborate with peers across the globe.The future of computing promises even greater advancements. Quantum computers, still in their infancy, hint at a new era of processing power, capable of solving problems that are currently intractable. Artificial intelligence, powered by sophisticated algorithms and vast datasets, is poised to redefine what machines can do, blurring the lines between human and computer capabilities.Yet, with great power comes great responsibility. The proliferation of computers has raised concerns about privacy, security, and the ethical use of technology. Cybersecurity has become a critical field, as individuals, corporations, and nations seek to protect their digital assets. The debate over artificial intelligence and automation touches on fundamental questions about the nature of work and the value of human labor.In conclusion, the computer, in its myriad forms, is indeed one of the greatest inventions of mankind. It has reshaped the world in countless ways, becoming an indispensable tool for progress and a mirror reflecting our collective aspirations and fears. As we stand on the cusp of new discoveries and challenges, the computer remains a symbol of human potential, a creation that has forever altered the course of history. 。

大学英语四级阅读200篇第6篇：学习计算机.doc
2019年6月大学英语四级阅读200篇第6篇：学习计算机There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal-combustion engine(内燃机)has something to do with burning fuel, expanding gases and pistons (活塞)being driven. For people should have some basic idea of how the things that they use do what they do. Further, students might be helped by a course that considers the computers impact on society. But that is not what is meant by computer literacy. For computer literacy is not a formof literacy (读写能力);it is a trade skill that should not be taught as a liberal art.Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who havechosen programming as a career. While programming can be lots of fun, and while our society needs some people who are experts at it, the same is true of auto repair and violin-making.Learning how to use a computer is not that difficult, and it gets easier all the time as programs become more user-friendly. Let us assume that in the future everyone is going to have to know how touse a computer to be a competent citizen. What does the phrase learning to use a computer mean? It sounds like learning to drive a car, that is, it sounds as if there is some set of definite skills that, once acquired,enable one to use a computer.In fact, learning to use a computer is much more like learning to play a game,but learning the rulesof one game may not help you play a second game, whose rules may not be the same. There is no such a thingas teaching someone how to use a computer. One can only teach people to use this or that program and generally that is easily accomplished.练习题：Choose correct answers to the question:1.To be the competent citizens of tomorrow, people should _______.A. try to lay a solid foundation in computer scienceB. be aware of how the things that they use do what they doC. learn to use a computer by acquiring a certain set of skillsD. understand that programming a computer is more essential than repairing a car2. In the second paragraphauto repairandviolin-makingare mentioned to show that _______ .A. programming a computer is as interesting as making a violinB. our society needs experts in different fieldsC. violin making requires as much skill as computer programmingD. people who can use a computer don’t necessarily have to know computer programming3. Learning to use a computer is getting easier all the time because _______ .A. programs are becoming less complicatedB. programs are designed to be convenient to usersC. programming is becoming easier and easierD. programs are becoming readily available to computer users4. According to the author,the phraselearning to use a computer(Lines3,4,Para.3) means learning _______.A. a set of rulesB. the fundamentals of computer scienceC. specific programsD. general principles of programming5. The author’s purpose in writing this passage is _______.A. to stress the impact of the computer on societyB. to explain the concept of computer literacyC. to illustrate the requirements for being competent citizens of tomorrowD. to emphasize that computer programming is an interesting and challenging job1.[C] 推理判断题。

It also allows arbitrary attributes, such as signing time, to be authenticated along with the message content, and provides for other attributes such as counter-signatures to be associated with a signature.CMS被用于数据签名或者任意消息加密中。
CMS提供了一套用于数据保护的数据封装语法。
该语法支持数据签名和数据加密。
该语法允许多重封装，所以一封数据信封能被另外一封数据信封所封装。
同样的，该语法封装数据的部分数据位可以用来表示被封装数据。
也允附加一些属性如签名时间，它和内容信息一起用于鉴别信息;计数器属性，它为其它属性提供计数信息。

CMS is used to digitally sign or encrypt arbitrary messages. CMS describes an encapsulation syntax for data protection. It supports digital signatures and Encryption. The syntax allows multiple encapsulation, so one encapsulation envelope can be nested inside another. Likewise, one party can digitally sign some previously encapsulated data. It also allows arbitrary attributes, such as signing time, to be authenticated along with the message content, and provides for other attributes such as counter-signatures to be associated with a signature.

XDM是XPath2.0的基础，它定义了XPath2.0的数据模型(因此XQuery 1.0 、XSLT 2.0也就基于XPath 2.0)。
XDM 建立在XML信息集(从XML文档中抽取)和PSVI(作为确认XML Schema结果的XML信息集合的注释类型)的顶端、属于简单的XML Schema的数据类型、是一个附加的概念。
其中，它最重要的附加概念就是顺序，即包括简单数据类型和XML的源节点。

Internet technical specifications often need to define a format syntax and are free to employ whatever notation their authors deem useful. Over the years, a modified version of BNF, called ABNF, has been popular among many Internet specifications. It balances compactness and simplicity with reasonable representational power.
互联网技术规范经常需要定义一种格式化语法并能自由地使用作者认为是有用的任何符号。
多年来，巴克斯范式
(BNF)的一个修订版，即扩展巴克斯范式(ABNF)，已经在许多互联网规范中流行。
该版本平衡了压缩性和简单性，具有合理的表达能力。
