关于网络好处的英语短文(我要像演讲稿的)
Internet CivilizationGood afternoon, ladies and gentleman! First I want to say is that I’m very proud of to be invited to to present my topic here, which is “ Internet Civilization”. Before I begin my topic, please allow me to ask you a question: Every time you click the mouse to surf the web, do you know what does it mean?On the net, you can make friends overseas and call them with IP phones; you can get information from all over the world; you can even give a hand to some people in troubles and get help when in need.However, we have to admit that internet also leads to intimacy before acquaintance; it scatters secrets outwards, not inwards; and, most worrying of all, it is a vehicle for liars.Here we should see, there exists good and evil, right and wrong on the web. As netizens, we’d better grow to realize the importance of Internet Civilization.Just as the famous saying goes “Long and steep is the path to virtue.” Many people advocate that we should be sincere, honest and responsible in our society—the real world. Now, what I want to add is that we also should obey the primary moral principles in this virtual world.All of my dear friends here, on the internet, which role did you play? Which role are you playing? And which role will you play?Thank you very much!

Today I'd like to talk about internet. I believe everyone sitting here knows internet a lot, and some of you are on the internet all the day. Internet has change our life dramatically. Nowdyas, we use internet to help with our work, to communicate with our friends, to search for information, to shop online, and to do innumerous other things. So many things we can do on the internet that I think most of people here cannot live without it now. However, as it brings significant convenience to our daily life, what's the disadvantages it has? The first thing I'd like to mention, is its harm to our health. Why? Because thanks to internet, we can manage to do many things by simply staring at the screen and clicking the mouse, which, eventually, is very likely to result in bad eyesight and obesity. In other words, Internet is stealing our excercise time! Not only this? Oh, my, the radioactive emission from the devices used for suffering online could actually cause you cancer?! In addition, a lot of computer viruses are hidden after a lot of links on the websites. Be careful! Control your curiosity! Otherwise, it'd be lucky if you only spend hundreds of dollars in fixing your computer and just losing some datas in your hardware. So, for your health concern, keep off the internet after using it for a while. Anyway, though sometimes the internet may sound a little scary, it's still a very useful tool. You just need to learn how to use it wisely. Thanks!

我帮到： （一）Today, the Internet is best described as a network of computers spread across the world, making use of fibre optic cables, telephone lines and satellites to communicate with other computers in the network. The Internet makes use of vacant bandwidth in the telecommunications network to send messages from computer to computer, rather than relying on an entirely new infrastructure. A standardised addressing system identifies specific computers, making it easy for other computers to hold information about what information other computers are storing and where they are. When we make use of the World Wide Web we are using this addressing system to go to a specific computer, either in Melbourne or possibly on the other side of the world, to read files stored on that computer. While any computer is connected to the network it is described as a node on the Internet, and with appropriate software we can use even a desktop computer to serve files to the rest of the world. It is the simplicity of this networking which has caused it to seize the imagination of users and to grow exponentially. The Internet, and particularly the World Wide Web, has revolutionised the way we communicate. It is likely that fax machines will go the way of the telegraph and the telex, and while the Internet in ten years will probably look quite different from that which we see now, it is certain to have become even more pervasive. The most commonly used parts of the Internet today include email, newsgroups, File Transfer Protocol, Internet Relay Chat, and of course the World Wide Web. Other areas which are rapidly growing include Internet telephony and video conferencing.）The Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a network of networks that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web. The Internet and the World Wide Web are not synonymous: the Internet is a collection of interconnected computer networks, linked by copper wires, fiber-optic cables, wireless connections, etc.; the Web is a collection of interconnected documents and other resources, linked by hyperlinks and URLs. The World Wide Web is accessible via the Internet, as are many other services including e-mail, file sharing, and others described below. The best way to define and distinguish between these terms is to understand the Internet protocol suite. This collection of protocols is organized into layers such that each layer provides the foundation and the services required by the layer above. In this conception, the term Internet refers to computer networks that all communicate with IP (Internet protocol) and TCP (transfer control protocol). Once this networking structure is established, then other protocols can run on top.” These other protocols are sometimes called services or applications. Hypertext transfer protocol, or HTTP, is an application layer protocol that links billions of files together into the World Wide Web. The Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a network of networks that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web. The USSR's launch of Sputnik spurred the United States to create the Advanced Research Projects Agency (ARPA, later known as the Defense Advanced Research Projects Agency, or DARPA) in February 1958 to regain a technological lead. ARPA created the Information Processing Technology Office (IPTO) to further the research of the Semi Automatic Ground Environment (SAGE) program, which had networked country-wide radar systems together for the first time. J. C. R. Licklider was selected to head the IPTO, and saw universal networking as a potential unifying human revolution. In 1950, Licklider moved from the Psycho-Acoustic Laboratory at Harvard University to MIT where he served on a committee that established MIT Lincoln Laboratory. He worked on the SAGE project. In 1957 he became a Vice President at BBN, where he bought the first production PDP-1 computer and conducted the first public demonstration of time-sharing. Licklider recruited Lawrence Roberts to head a project to implement a network, and Roberts based the technology on the work of Paul Baran who had written an exhaustive study for the U.S. Air Force that recommended packet switching (as opposed to Circuit switching) to make a network highly robust and survivable. After much work, the first node went live at UCLA on October 29, 1969 on what would be called the ARPANET, one of the eve networks of today's Internet. Following on from this, the British Post Office, Western Union International and Tymnet collaborated to create the first international packet switched network, referred to as the International Packet Switched Service (IPSS), in 1978. This network grew from Europe and the US to cover Canada, Hong Kong and Australia by 1981. The first TCP\\\/IP wide area network was operational by 1 January 1983, when the United States' National Science Foundation (NSF) constructed a university network backbone that would later become the NSFNet. (This date is held by some to be technically that of the birth of the Internet.) It was then followed by the opening of the network to commercial interests in 1985. Important, separate networks that offered gateways into, then later merged with, the NSFNet include Usenet, Bitnet and the various commercial and educational X.25 Compuserve and JANET. Telenet (later called Sprintnet), was a large privately-funded national computer network with free dialup access in cities throughout the U.S. that had been in operation since the 1970s. This network eventually merged with the others in the 1990s as the TCP\\\/IP protocol became increasingly popular. The ability of TCP\\\/IP to work over these pre-existing communication networks, especially the international X.25 IPSS network, allowed for a great ease of growth. Use of the term Internet to describe a single global TCP\\\/IP network originated around this time. The network gained a public face in the 1990s. On August 6th, 1991 CERN, which straddles the border between France and Switzerland publicized the new World Wide Web project, two years after Tim Berners-Lee had begun creating HTML, HTTP and the first few Web pages at CERN. An early popular Web browser was ViolaWWW based upon HyperCard. It was eventually replaced in popularity by the Mosaic Web Browser. In 1993 the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign released version 1.0 of Mosaic and by late 1994 there was growing public interest in the previously academic\\\/technical Internet. By 1996 the word Internet was coming into common daily usage, frequently misused to refer to the World Wide Web. Meanwhile, over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks (although some networks such as FidoNet have remained separate). This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary open nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network.

Time - the world's fastest and most slowly, the longest yet shortest, the most extraordinary and most valuable and most easily overlooked and most other things that people regret.

Some people's lives continues to accomplish these meaningful, then the value of his work are embodied in the study came out, only to do more and do better, the greater the value of life; the contrary, a person continually to waste time, the value of his life will be miserable.You love life?
