1、計(jì)算機(jī)專業(yè)英語(yǔ)主講：焦陽(yáng)Chapter 2：The Internet, the Web, and Electronic Commerce1Discuss the origins of the Internet and the Web.Describe how to access the Web using providers and browsers.Discuss Internet communications, including e-mail, instant messaging, and social networking.Describe search tools, includin

2、g search engines, metasearch engines, and specialized search engines.Evaluate the accuracy of information presented on the Web.Discuss electronic commerce, including B2C, C2C, B2B, and security issues.Describe these Web utilities: Web-based applications, FTP, plug-ins, and filters.By the end of the

3、chapter, you should be able to：2The Internet was launched in 1969 when the United States funded a project that developed a national computer network called Advanced Research Project Agency Network (ARPANET). The Internet is a large network that connects together smaller networks all over the globe.

4、The Web was introduced in 1992 at the Center for European Nuclear Research (CERN) in Switzerland.因特網(wǎng)首創(chuàng)于1969年，當(dāng)時(shí)美國(guó)政府撥款開發(fā)了一個(gè)全國(guó)的計(jì)算機(jī)網(wǎng)絡(luò)，叫做阿帕網(wǎng)。這個(gè)因特網(wǎng)是一個(gè)巨大的網(wǎng)絡(luò)，它把全球的小型網(wǎng)絡(luò)都連接在一起。萬(wàn)維網(wǎng)是1992年在瑞士的歐洲核子研究中心被引進(jìn)的。The Internet and the Web3 Prior to the Web, the Internet was all textno graphics, animations, sound, or vid

5、eo. The Web made it possible to include these elements. It provided a multimedia interface to resources available on the Internet. From these early research beginnings, the Internet and the Web have evolved into one of the most powerful tools for the 21st century. 在萬(wàn)維網(wǎng)之前，因特網(wǎng)全部都是文字沒有任何圖像，動(dòng)畫，聲音，視頻。萬(wàn)維網(wǎng)

6、使得包含這些元素變成了可能。它為因特網(wǎng)上的有效資源提供了一個(gè)多媒體的界面。從這些早期的研究開始之后，因特網(wǎng)與萬(wàn)維網(wǎng)就已經(jīng)演變成了21世紀(jì)最強(qiáng)大的工具之一。The Internet and the Web4It is easy to get the Internet and the Web confused, but they are not the same thing. The Internet is the actual physical network. It is made up of wires, cables, and satellites. Being connected to

7、this network is often described as being online. The Internet connects millions of computers and resources available on the Internet. Every day over a billion users from nearly every country in the world use the Internet and the Web. What are they doing? The most common uses are the following:我們很容易將

8、因特網(wǎng)與萬(wàn)維網(wǎng)弄混淆，盡管它們不是同一個(gè)概念。因特網(wǎng)實(shí)際上指的是物理的網(wǎng)絡(luò)。它由電線，電纜和衛(wèi)星組成。我們常常把連接到這個(gè)物理的網(wǎng)絡(luò)說(shuō)成是正在聯(lián)線。因特網(wǎng)將成千上萬(wàn)的計(jì)算機(jī)和因特網(wǎng)上的有效資源連接起來(lái)。每一天都有超過十億的來(lái)自世界各地的用戶使用因特網(wǎng)和萬(wàn)維網(wǎng)。他們都在做什么呢？最常見的用途有以下幾種：The Internet and the Web5Communicating is by far the most popular Internet activity. You can exchange e-mail with your family and friends almost anyw

9、here in the world. You can join and listen to discussions and debates on a wide variety of special-interest topics.通訊是迄今為止最受歡送的互聯(lián)網(wǎng)活動(dòng)。你可以與你的家人以及幾乎世界上任何地方的朋友互換電子郵件。你可以參加并且聆聽討論，以及對(duì)很廣范圍的關(guān)于特殊興趣的話題進(jìn)行爭(zhēng)論。Shopping is one of the fastest-growing Internet applications. You can window shop, look for the latest f

10、ashions, search for bargains, and make purchases.購(gòu)物也是一種迅速增長(zhǎng)的互聯(lián)網(wǎng)應(yīng)用。你可以只看不買，找尋最新的時(shí)尚，搜索特價(jià)商品并購(gòu)置商品。The Internet and the Web6Searching for information has never been more convenient. You can access some of the worlds largest libraries directly from your home computer. You can find the latest local, nation

11、al, and international news.搜索信息已經(jīng)變得不能比這再簡(jiǎn)便了。你可以從你家里的計(jì)算機(jī)直接訪問到一些世界上最大的圖書館。你也可以找到最新的地方的，國(guó)家的以及國(guó)際的新聞。Entertainment options are nearly endless. You can find music, movies, magazines, and computer games. You will find live concerts, movies previews, book clubs, and interactive live games.娛樂的選項(xiàng)幾乎是無(wú)窮無(wú)盡的。你可以找

12、到音樂，電影，雜志和計(jì)算機(jī)游戲。你也會(huì)找到現(xiàn)場(chǎng)直播的音樂會(huì)，電影的預(yù)映，圖書俱樂部以及互動(dòng)的在線游戲。The Internet and the Web7Education or e-learning is another rapidly emerging Web application. You can take classes on almost any subject. There are courses just for fun and there are courses for high school, college, and graduate school credit. Some

13、 cost nothing to take and others cost a lot.教育或者是電子學(xué)習(xí)是另一種迅速興起的網(wǎng)上應(yīng)用。你可以上幾乎任意一門學(xué)科的課。有的課程僅僅是為了娛樂，有的課程是高中，大學(xué)和研究所的課程。The first step to using the Internet and Web is to get connected, or to gain access to the Internet.第一步就是使用互聯(lián)網(wǎng)和萬(wàn)維網(wǎng)來(lái)進(jìn)行連接，或者是說(shuō)得以訪問互聯(lián)網(wǎng)。The Internet and the Web8Describe how the Internet and t

14、he Web started.What is the difference between the Internet and the Web?List and describe five of the most common used of the Internet and the Web.Concept Check9The Internet and the telephone system are similaryou can connect a computer to the Internet much like you connect a phone to the telephone s

15、ystem. Once you are on the Internet, your computer becomes an extension of what seems like a giant computera computer that branches all over the world. When provided with a connection to the Internet, you can use a browser program to search the Web.互聯(lián)網(wǎng)和 系統(tǒng)很相似你可以將一臺(tái)計(jì)算機(jī)連接到互聯(lián)網(wǎng)上，就像你把一部 連接到 系統(tǒng)上。一旦你連上互聯(lián)網(wǎng)了

16、，你的計(jì)算機(jī)就變成了一個(gè)巨型計(jì)算機(jī)的分機(jī)，這個(gè)巨型機(jī)在全世界都有分支。Access10The most common way to access the Internet is through an Internet service provider (ISP). The providers are already connected to the Internet and provide a path or connection for individuals to access to the Internet either through its local area networks o

17、r through a dial-up or telephone connection. There are also some companies that offer free Internet access.訪問互聯(lián)網(wǎng)最常見的方式是通過一個(gè)互聯(lián)網(wǎng)效勞供給者。這些供給者是已經(jīng)和互聯(lián)網(wǎng)連上了，他們?yōu)榻K端用戶提供路徑，從而使用戶們可以通過局域網(wǎng)或是撥號(hào)，或是 連接來(lái)訪問到互聯(lián)網(wǎng)。有些公司有提供免費(fèi)的互聯(lián)網(wǎng)訪問權(quán)。Access:providers11The most widely used commercial Internet service providers are national an

18、d wireless providers.最普遍使用的商業(yè)互聯(lián)網(wǎng)效勞提供商是國(guó)家的和無(wú)線提供商。National service providers like American Online (AOL) are the most widely used. They provide access through standard telephone or cable connections. Users can access the Internet from almost anywhere within the country for a standard fee without incurr

19、ing long-distance telephone charges.像美國(guó)在線這樣全國(guó)性的效勞提供商是使用最廣泛的。他們通過標(biāo)準(zhǔn)的 或電纜連接來(lái)提供訪問。用戶們可以從幾乎全國(guó)的任意一個(gè)地方訪問互聯(lián)網(wǎng)，只需付一個(gè)標(biāo)準(zhǔn)的費(fèi)用而不會(huì)引起長(zhǎng)途 費(fèi)的價(jià)格。Access: providers12Wireless service providers do not use telephone or cable lines. They provide Internet connections for computers with wireless modems and a wide array of wir

20、eless devices.無(wú)線效勞商既不使用 ，也不使用電纜線。他們?yōu)榘惭b有無(wú)線調(diào)制解調(diào)器的電腦以及很多系列的無(wú)線設(shè)備提供互聯(lián)網(wǎng)連接。As we will discuss in Chapter 9, users connect to ISPs using one of a variety of connection technologies including dial-up, DSL, cable, and wireless modems.我們將會(huì)在第九章里討論，用戶通過很多不同類型的連接技術(shù)與互聯(lián)網(wǎng)效勞供給商相連，包括撥號(hào)，數(shù)字用戶線，電纜以及無(wú)線調(diào)制解調(diào)器。Access: provid

21、ers13Browsers are programs that provide access to Web resources. This software connects you to remote computers, opens and transfers files, displays text and images, and provides in one tool an uncomplicated interface to the Internet and Web documents. Browsers allow you to explore, or to surf, the

22、Web by easily moving from one Web site to another. Three well-known browsers are Mozilla Firefox, Netscape Communications, and Microsoft Internet Explorer.瀏覽器是給網(wǎng)絡(luò)資源提供訪問的程序。這種軟件使得你可以和遠(yuǎn)處的計(jì)算機(jī)連接起來(lái)，翻開并傳送文件，顯示文字和圖像，將這些功能集合成一個(gè)工具，為互聯(lián)網(wǎng)和網(wǎng)絡(luò)文件提供了一個(gè)不復(fù)雜的界面。瀏覽器使你可以探索或是漫游網(wǎng)絡(luò)輕松地從一個(gè)網(wǎng)站移動(dòng)到另一個(gè)網(wǎng)站。三種最熟悉的瀏覽器是Mozilla的火狐瀏覽器，網(wǎng)

23、景通訊，和微軟的Internet Explorer.Access: browsers14For browsers to connect to resources, the location or address of the resources must be specified. These addresses are called uniform resource locators (URLs). All URLs have at least two basic parts. The first part presents the protocol used to connect to t

24、he resource. As we will discuss in Chapter 9, protocols are rules for exchanging data between computers. The protocol :/ is the most widely used Web protocol. The second part presents the domain name. It is the name of the server where the resource is located.為了使得瀏覽器可以連接到資源，這些資源的位置或是地址必須有規(guī)定。這些地址叫做統(tǒng)一

25、資源定位符簡(jiǎn)稱URLs。所有的統(tǒng)一資源定位符都有至少兩個(gè)根本組成局部。第一局部顯示的是連接資源所使用的協(xié)議。我們?cè)诘诰耪聲?huì)討論到，協(xié)議是計(jì)算機(jī)之間交換數(shù)據(jù)的規(guī)那么。協(xié)議“ :/是使用最廣泛的網(wǎng)絡(luò)協(xié)議。第二局部顯示的是域名。它是放置那個(gè)資源的效勞器的名字。Access: browsers15In Figure 2-4 the server is identified as . (many URLs have additional parts specifying directory paths, file names, and pointers.) The last part of the do

26、main name following the dot (.) is the top-level domain (TLD). It identifies the type of organization. For example, indicates a commercial site. The URL connects your computer to a computer that provides information about MTV.在圖2-4里，效勞器被定為。許多統(tǒng)一資源定位符都有附加的局部來(lái)制定文件夾路徑，文件名稱和指針在域名中，跟著點(diǎn)的最后一局部是最高級(jí)的域名簡(jiǎn)稱TLD。它

27、指示了組織的類型。比方，“ 標(biāo)志一個(gè)商業(yè)網(wǎng)站。而URL那么將你的電腦和一個(gè)提供關(guān)于MTV信息的電腦聯(lián)系起來(lái)。Access: browsers16Once the browser has connected to the Web site, a document file is sent back to your computer. This document typically contains Hypertext Markup Language (HTML) commands. The browser interprets the HTML commands and displays the

28、 document as a Web page. For example, when your browser first connects to the Internet, it opens up to a Web page specified in the browser settings. This page presents information about the site along with references and hyperlinks or links that connect to other documents containing related informat

29、iontext files, graphic images, audio, and video clips.一旦瀏覽器和網(wǎng)站連接起來(lái)，一個(gè)文檔文件就會(huì)送回你的計(jì)算機(jī)。這個(gè)文檔通常包含超文本鏈接標(biāo)示語(yǔ)言指令。瀏覽器可以讀懂HTML指令，并將文檔以網(wǎng)頁(yè)的形式顯示。例如，當(dāng)你的瀏覽器第一次連接到互聯(lián)網(wǎng)，它會(huì)翻開一個(gè)網(wǎng)頁(yè)用來(lái)規(guī)定瀏覽器的設(shè)置。這個(gè)網(wǎng)頁(yè)顯示關(guān)于站點(diǎn)的信息，同時(shí)還有標(biāo)記，超鏈接或著包含其它相關(guān)信息包括文字文檔，平面圖像，音頻和視頻片段的鏈接。Access: browsers17These documents may be located on a nearby computer syste

30、m or on one halfway around the world. The links typically appear on the Web page as underlined and colored text and/or images. To access the referenced material, all you do is click on the highlighted text or image. A connection is automatically made to the computer containing the material, and the

31、referenced material appears on your display screen.這些文檔也許被放置在一個(gè)離你很近的計(jì)算機(jī)系統(tǒng)，也許被放置在一個(gè)距你在地球另一邊的計(jì)算機(jī)。這些鏈接通常在網(wǎng)頁(yè)上顯示為有下劃線的和有顏色的文字或圖片。要想訪問到這些參考材料，你只需要在這些突出的文字或圖片上點(diǎn)擊一下。一個(gè)鏈接就會(huì)自動(dòng)地接到那臺(tái)含有材料的計(jì)算機(jī)，并且這些參考材料就會(huì)在你的顯示屏上出現(xiàn)了。Access: browsers18Web pages also can contain special programs called applets that are typically writ

32、ten in a programming language such as Java. These programs can be downloaded quickly and run by most browsers. Java applets are widely used to add interest and activity to a Web site by presenting animation, displaying graphics, providing interactive games, and much more.網(wǎng)頁(yè)也包含特殊的程序叫做微程序，通常是由例如Java這樣

33、的編程語(yǔ)言編寫的。這些程序可以被大多數(shù)瀏覽器迅速地下載并運(yùn)行。Java微程序廣泛應(yīng)用于給網(wǎng)站增加趣味和活力，它通過展示動(dòng)畫，顯示圖片，提供交互式游戲還有其它很多手段等等。Access: browsers19What is the function of an ISP? Describe two types of ISPs.What is the function of a browser?What are URLs, HTML, Web pages, hyperlinks, applets, and Java?Concept check20As previously mentioned, co

34、mmunication is the most popular Internet activity, and its impact cannot be overestimated. At a personal level, friends and family can stay in contact with one another even when separated by thousands of miles. At a business level, electronic communication has become a standard, and many times prefe

35、rred, way to stay in touch with suppliers, employees, and customers. The three most popular types of Internet communication are e-mail, instant messaging, and discussion groups.正如之前提到的，通訊是應(yīng)用最廣泛的互聯(lián)網(wǎng)活動(dòng)，它的影響不能被高估。在個(gè)人的層面，朋友和家人即使分隔千里也可以保持聯(lián)系。在商業(yè)的層面，電子通訊已經(jīng)變成了一種標(biāo)準(zhǔn)，很多時(shí)候是首選的，與供給商，員工以及客戶保持聯(lián)系的方式。三種最流行的互聯(lián)網(wǎng)通信類型是電

36、子郵件，即時(shí)通訊和討論小組。Communication21E-mail or electronic mail is the transmission of electronic messages over the Internet. At one time, e-mail consisted only of basic text messages. Now e-mail routinely includes graphics, photos, and many different types of file attachments. People all over the world send

37、 e-mail to each other. You can e-mail your family, your co-workers, and even your senator. All you need to send and receive e-mail is an e-mail account, access to the Internet, and an e-mail program. Two of the most widely used e-mail programs are Microsofts Outlook Express and Mozilla Thunderbird.電

38、子郵件是電子信息在互聯(lián)網(wǎng)上的傳播。曾經(jīng)，電子郵件被認(rèn)為只是根本的文字信息?，F(xiàn)在電郵慣常地包含圖片、照片和許多不同種類的文件附件。全世界的人們互相發(fā)郵件。你可以給你的家人，你的同事，甚至你的參議員發(fā)郵件。要收發(fā)電郵只需要有一個(gè)電郵賬戶，訪問到互聯(lián)網(wǎng)和一個(gè)電郵軟件就可以了。兩個(gè)最廣泛使用的電郵軟件是微軟的Outlook Express和Mozilla的Thunderbird雷鳥。Communication: E-mail22A typical e-mail message has three basic elements: header, message, and signature. The h

39、eader appears first and typically includes the following information:一個(gè)典型的電郵信息有三個(gè)根本元素：標(biāo)題，信息和簽名。首先出現(xiàn)的是標(biāo)題，它通常包含以下信息：Communication: E-mail23Addresses: Addresses of the persons sending, receiving, and, optionally, anyone else who is to receive copies. E-mail addresses have two basic parts. The first par

40、t is the users name and the second part is the domain name, which includes the top-level domain. In our example e-mail, dcoats is Dans user name. The server providing e-mail service for Dan is . The top-level domain indicates that the provider is an educational institution.地址：人們收信發(fā)信的地址，還有那些可以選擇地，任何能

41、收到抄送本的人。電郵地址也有兩個(gè)根本局部。第一局部是用戶的名字，第二局部是域名，包括頂級(jí)域名。在我們的電郵例子(dcoats)里，dcoats是Dan的用戶名。為Dan提供電郵效勞的效勞器是。這個(gè)頂級(jí)域名指出了提供者是一個(gè)教育機(jī)構(gòu)。Communication: E-mail24Subject: A one-line description, used to present the topic of the message. Subject lines typically are displayed when a person checks his or her mailbox.主題：一個(gè)一行的

42、描述，用來(lái)顯示信息的話題。主題行通常是在人們檢查郵箱的時(shí)候會(huì)顯示。Attachments: Many e-mail programs allow you to attach files such as documents and worksheets. If a message has an attachment, the file name appears on the attachment line.附件：許多電郵軟件都允許你附上諸如文檔和工作表一類文件。如果一封郵件有一個(gè)附件，這個(gè)文件名就會(huì)出現(xiàn)在附件行上。Communication: E-mail25The letter or mess

43、age comes next. It is typically short and to the point. Finally, the signature line provides additional information about the sender. Typically, this information includes the senders name, address, and telephone number.接著是信或者短信。它通常很短，簡(jiǎn)明扼要。最后簽名檔提供一些關(guān)于發(fā)信人的附加信息。通常的，這個(gè)信息包括發(fā)信人的名字、地址和 號(hào)碼。Communication: E-

44、mail26E-mail can be a valuable asset in your personal and professional life. However, like many other valuable technologies, there are drawbacks too. Americans receive billions of unwanted and unsolicited e-mail every year. This unwelcome mail is called spam. While spam is indeed a distraction and n

45、uisance, it also can be dangerous. For example, computer viruses or destructive programs are often attached to unsolicited e-mail. 電子郵件可以成為你個(gè)人和職業(yè)生活中一筆很重要的財(cái)富。盡管如此，像很多其它有價(jià)值的技術(shù)一樣，它也有缺點(diǎn)。美國(guó)人每年會(huì)收到上億封不需要并且未經(jīng)許可的電子郵件。這種不受歡送的郵件被稱之為垃圾郵件。盡管垃圾郵件很令人分心又令人討厭，它也可以變得很危險(xiǎn)。比方說(shuō)，計(jì)算機(jī)病毒或者是破壞性的程序就常常被附在未經(jīng)許可的電郵里。Communication:

46、 E-mail27In an attempt to control spam, anti-spam laws have been added to our legal system. For example, the recently enacted CAN-SPAM Act requires that every marketing related e-mail provide an opt-out option. When the option is selected, the recipients e-mail address is to be removed from future m

47、ailing lists. Failure to do so results in heavy fines. This approach, however, has had minimal impact since over 50 percent of all spam originates from servers outside the United States. A more effective approach has been the development and use of spam blockers. These programs use a variety of diff

48、erent approaches to identify and eliminate spam. 嘗試著控制垃圾郵件，反垃圾郵件法已經(jīng)被增加到我們的法律系統(tǒng)。比方，最近通過的CAN-SPAM法就要求每封與營(yíng)銷有關(guān)的電郵都要提供一個(gè)選擇排除的選項(xiàng)。當(dāng)這個(gè)選項(xiàng)被選中，收信人的電郵地址將會(huì)從未來(lái)的郵件發(fā)送清單里除去。不這樣做的話會(huì)導(dǎo)致巨額的罰款。盡管如此，這個(gè)手段的作用并不大，因?yàn)槌^50%以上的垃圾郵件都源自于美國(guó)以外的效勞器。一種更有效的手段就是開發(fā)和使用垃圾郵件攔截器。這些軟件使用多種不同的手段來(lái)識(shí)別并消除垃圾郵件。Communication: E-mail28Instant messagin

49、g (IM) is an extension of e-mail that allows two or more people to contact each other via direct, live communication. To use instant messaging, you specify a list of friends and register with an instant messaging server. Whenever you connect to the Internet, special software informs your messaging s

50、erver that you are online. In response, the server will notify you if any of your contacts are online. At the same time, it notifies your friends that you are online. You can then send messages directly back and forth to one another. Most instant messaging programs also include video conferencing fe

51、atures, file sharing, and remote assistance. Many businesses routinely use these instant messaging features.即時(shí)通訊簡(jiǎn)稱IM是電子郵件的一個(gè)延伸，它允許兩個(gè)或多個(gè)人通過直接，實(shí)時(shí)的通訊來(lái)互相聯(lián)系。要使用即時(shí)通訊，你要制定一個(gè)朋友的名單，并在一個(gè)即時(shí)通訊效勞器上注冊(cè)。當(dāng)你連接到互聯(lián)網(wǎng)，專門的軟件會(huì)通知你的短信效勞器你已經(jīng)在線了。作為回應(yīng)，這臺(tái)效勞器會(huì)通知你如果你有朋友也在線的話。同時(shí)，它也會(huì)通知你的朋友，你在線了。你可以將短信直接來(lái)回地傳給另一個(gè)人。大多數(shù)的即時(shí)通訊軟件也包括了視頻會(huì)議的功

52、能，文件共享以及遠(yuǎn)程幫助。很多商業(yè)也慣常使用這些即時(shí)通訊的功能。Communication: Instant messaging29The most widely used instant messaging services are AOLs Instant Messenger, Microsofts MSN Messenger, and Yahoo Messenger. One limitation, however, is that many instant messaging services do not support communication with other servic

53、es. For example, at the time of this writing, a user registered with AOL cannot use AOLs Instant Messenger software to communicate with a user registered with Yahoo Messenger. Recently, however, some software companies have started providing universal instant messenger programs that overcome this li

54、mitation. For example, Gain, Odigo, and Thrilian provide instant messaging services that do support communication with other services.使用最廣泛的即時(shí)通訊效勞是美國(guó)在線的Instant Messenger,微軟的MSN Messenger，以及雅虎的Messenger。然而有一個(gè)局限就是，許多即時(shí)通訊效勞都不支持與其它通訊效勞相聯(lián)系。比方說(shuō)，在寫這本書時(shí)侯，一個(gè)在AOL上注冊(cè)的用戶不能用AOL的Instant Messenger軟件與在Yahoo Messeng

55、er上注冊(cè)的用戶進(jìn)行交流。然而近來(lái)，一些軟件公司已經(jīng)開始提供萬(wàn)能的即時(shí)通訊軟件來(lái)克服這個(gè)限制。例如，Gain，Odigo和Thrilian都提供支持與其它效勞可以溝通的即時(shí)通訊效勞。Communication: Instant messaging30One of the fastest-growing uses of the Internet is social networking, or connecting individuals to one another. There are three basic categories of social networking sites: re

56、uniting, friend-of-a-friend, and common interest.互聯(lián)網(wǎng)的一項(xiàng)增長(zhǎng)十分迅猛的應(yīng)用就是社交網(wǎng)絡(luò)，或者是將個(gè)人都聯(lián)系起來(lái)。有三種根本類型的社交網(wǎng)站：重聚型，朋友圈型以及共同愛好型。Communication: Social networking31Reuniting sites are designed to connect people who have known one another but have lost touch; for example, an old high school friend that you have not se

57、en for several years. You join a social network by connecting to a reuniting site and providing profile information such as your age, gender, name of high school, and so forth. This information is added to the reuniting sites member database. Members are able to search the database to locate individ

58、uals. Many of the sites will even notify you whenever a new individual joins that matches some parts of your profile (such as high school class). Two of the best-know reuniting sites are Classmates Online and Facebook.重聚型網(wǎng)站是為了那些已經(jīng)認(rèn)識(shí)但卻失去聯(lián)系的人設(shè)計(jì)的；例如，一個(gè)你高中時(shí)的老朋友已經(jīng)好些年沒見了。你參加這樣的社交網(wǎng)絡(luò)，通過連接到一個(gè)重聚型網(wǎng)站并且提供你的年齡，性別

59、，高中名稱等諸如此類的簡(jiǎn)介信息。這個(gè)信息被添加到這個(gè)重聚型網(wǎng)站的會(huì)員數(shù)據(jù)庫(kù)里。這樣會(huì)員就可以通過搜索數(shù)據(jù)庫(kù)來(lái)找到單獨(dú)的人。許多這樣的網(wǎng)站甚至?xí)ㄖ悖诿慨?dāng)一位新人參加到與你的簡(jiǎn)介信息例如高中的班級(jí)有公同地方的時(shí)候。兩個(gè)最有名的重聚型網(wǎng)站是Classmates Online和Facebook.Communication: Social networking32Friend-of-a-friend sites are designed to bring together two people who do not know one another but share a common frien

60、d. The theory is that, if you share a common friend, then it is likely that you would become friends. For example, a network could be started by one of your acquaintances by providing profile information on him- or herself and a list of friends. You could even join the list of friends provided at th
