A global network connecting millions of computers. 2. The transmission of messages over communications networks. 3. A system of Internet servers that support specially formatted documents. 4.3. Now read the text and try to describe the Internet again using the key vocabulary in bold type.Believe it or not, the Internet was created way back in 1969, during the Cold War, by the United States military. It was meant to be a "nuke-proof"(1) communications network. Today, the Internet spreads across the globe and consists of countless networks and computers, allowing millions of people to share information. Data that travels long distances on the Internet is transferred on huge lines known collectively as the Internet backbone. The Internet is now maintained by the Internet service pro-viders.Many people think the Internet and the World Wide Web are the same thing. They're not! The World Wide Web is what you are browse. It is one of the many features of the Internet. E-mail, FTP(2), and Instant Messaging (3) are also features of the Internet.(http://www.sharpened.net)(1) "nuke-proof" устойчивый к воздействию ядерного оружия(2) FTP File Transfer Protocol протокол передачи файлов (используемый в Internet протокол передачи файлов между хост-компьютерами)(3) Instant Messaging система мгновенной передачи текстовых сооб-щений4.4. Interview your partners if they surf the Internet. Use the questions given below. Do you often surf the Internet? Which websites do you usually visit? Do you download any programs from the Internet? If so, what are they? Do you belong to any chat forum? Why? / Why not? What feature of the Internet do you consider the most attractive? Why? What is netiquette? 4.5. Read the passage below and think if you always follow the netiquette. Why? / Why not? Discuss it with your partner.Netiquette, or net etiquette, refers to etiquette on the Internet. Good netiquette involves respecting others' privacy and not doing anything online that will annoy or frustrate other people. Three areas where good netiquette is highly stressed are e-mail, online chat, and newsgroups. For example, people that spam other users with unwanted e-mails or flood them with messages have very bad netiquette. You don't want to be one of those people. If you're new to a newsgroup or online chat room, it may help to observe how people communicate with each other before jumping in.4.6.Think of good and bad points of the Internet and fill in the table. You can work either individually or in pairs. Advantages of the Internet Disadvantages of the Internet 4.7. Read Text A, compare your ideas with information given, and extend the table. How many advantages/disadvantages are there in your table? First, study the vocabulary you may need to understand the text.mankind [mæn'kaɪnd] (n) 1) человечество; человеческий род ['mænkaɪnd] 2) мужчины, мужской полmagnitude ['mæɡnɪtju:d] (n) 1) величина, paзмеры, 2) важность; значимостьoutweigh [̗aυt'weɪ] (v) быть тяжелее, превосходить в весеwealth [welθ] (n) изобилие, избытокtarget ['tɑ:ɡɪt] (n) цельadvent ['ædvent] (n) наступление (какой-л. эпохи, какого-л. события), available [ə'veɪləbl] (adj) доступный; имеющийся в распоряжении, entertainment [̗entə'teɪnmənt] (n) развлечение; зрелищное мероприятиеnumerous ['nju:mǝrəs] (adj) многочисленныйavailable [ə'veɪləbl] (adj) доступный; имеющийся в распоряженииtheft [θeft] (n) воровство, кражаobstruct [əb'strʌkt] (v) препятствовать, затруднять, мешатьprone (adj) подверженный (чему-л.)TEXT AAdvantages and Disadvantages of the InternetThe Internet has been perhaps the most outstanding innovation in the field of communication in the history of mankind. As with every single innovation, the Internet has its own advantages and disadvantages. But usually, greater magnitude of advantages outweighs its disadvantages. Today the Internet has brought a globe in a single room. Right from news across the corner of the world, wealth of information to shopping, purchasing the tickets of your favourite movie.Advantages CommunicationThe main target of the Internet has always been the communication. By the advent of the Internet, our earth has become a global village. Now we can communicate with a person who is sitting in the other part of the world.Information Information is probably the biggest advantage the Internet offers. Students and children are among the top users who surf the Internet for research. Today, it is almost required that students should use the Internet for research purpose of gathering resources. Entertainment Downloading games, visiting chat rooms or just surfing the Web are some of the entertainments. In fact, the Internet has been successfully used by people to find life long partners. When people surf the Web, there are numerous things that can be found. Music, hobbies, news and more can be found and shared on the Internet. Services Many services are now provided on the Internet such as online banking, job seeking, purchasing tickets. Often these services are not available off-line or can cost you more. E-Commerce It has got a really amazing and wide range of products from technology to household needs. Disadvantages Theft of personal information If you use the Internet, you may be facing danger as your personal information such as name, address, credit card number, etc. can be accessed and used by a criminal.SpammingSpamming refers to sending unwanted e-mails, which provide no purpose and obstruct the entire system. Virus threat Computers attached to the Internet are more prone to virus attacks and they can end up into crashing your whole hard disk. PornographyThis is perhaps the biggest threat related to your children’s healthy mental life. (http://www.buzzle.com)4.8. Match the words below to make word partners.1. global a. chat rooms2. surf b. privacy3. visit c. danger4. download d. village5. household e. needs6. face f. disk7. hard g. the Internet8. respect h. games4.9. Now use the word partners to complete these sentences.

Discuss if you always trust the information from the Internet? Why/Why not?Now skim Text B and say what the main idea of the text is.4.12. Read Text B and give your ideas on what could help Zack to understand that Professor Butz's Web page wasn't a reliable source of information?(To understand the text better use the vocabulary given below.)TEXT BThe Web – Teaching Zack to ThinkAs more and more students access the Internet for research, it's important that they learn how to validate online information. The Internet is a place where you can find "proof" of almost any belief system that you can imagine. And, for too many students, "If it's on the Internet, it must be true."The following story is also true.Fourteen-year-old Zack was asked to research a unique topic for his history class. Zack knew a bit about using reliable sources on the Internet, so when he found some information on a Web page on the US Northwestern University site he felt sure that he had found a reliable source of information for his project. The topic was unique too–Holocaust Revisionism–Zack had never heard of that before, so he decided to write his history paper on "How the Holocaust Never Happened."Zack found his "information" from a Web page at http://pubweb. northwestern.edu/abutz/ (no longer at this URL), titled "Home Web Page of Arthur R. Butz." On his low-key home page, Butz explained that he wrote "A short introduction to the study of Holocaust revisionism" and that his material was intended for "advanced students of Holocaust revisionism." At the top of the page Butz identified himself as "Associate Professor of Electrical and Computer Engineering, Northwestern University». His article began with the following: “I see principal reasons for the widespread but erroneous belief in the legend of millions of Jews killed by the Germans during World War II: During both world wars Germany was forced to fight typhus… That was one of the main reasons for a high death rate in the camps, and the crematoria... Look at the above situation from the perspective of a 14-year-old, untrained to think critically about information. He's researching the Holocaust, and suddenly finds this Web page. His teacher told him to find a unique topic, and this certainly fit the bill. The page is simple and clear. It's written in a calm, logical tone. The page is clearly intended for experts in its field. Best of all is the source: Northwestern University! And a professor to boot! Perfect. validate ['vælɪdeɪt] v проверять достоверностьproof [pru:f] (n) доказательствоbelief [bɪ'li:f] (n) убеждение, мнение; вераreliable [rɪ'laɪ əbl] (adj) заслуживающий доверия, достоверныйreliable information – достоверные сведенияreliable source – достоверный, надежный источникlow-key (adj) 1) неброский; сдержанный2) гамма тёмных тоновin a lowkey – в тёмных тонах Associate Professor доцент университетаwidespread ['waɪdspred] (adj) широко распространённыйerroneous [ɪ'rəυnɪəs] (adj) ложный; ошибочный;typhus ['taɪfəs] (n) сыпной тифfit the bill отвечать всем требованиямto boot к общей пользе; вдобавок; к тому же4.13. Now read Text C and check your ideas. (To understand the text better use the vocabulary given below.)TEXT CThinking about What We've FoundThe fact is that students increasingly depend on the Internet for information, so it's important that they develop ways to evaluate their findings. Zack could have used some, or all, of the following techniques to decide whether the site was a reliable source for information.PurposeTry to determine a Web site's purpose. What is it trying to do? Why was it created? Most Web sites are designed to sell services and products, present information, put ideas forward, or entertain. Many sites do several of these at once.A Web site's purpose will not always be clear. Look at Butz's site. His purpose is surely advocacy, although he comes across as an objective information provider, especially in the closing sentence of his article: "Surely any thoughtful person must be skeptical." Would a 14-year-old know how to distinguish between objective information and propaganda?Understand the purpose(s) of a Web site, and that those purpose(s) may not be entirely obvious. Author The next step in validation involves the site's author. We all know that it's easy to fool people. Many people will believe someone if he or she sounds authoritative. Butz is a professor, sure, but he's an Engineering professor. How does that qualify him to speak as an expert on the Holocaust? It doesn't. But people see "Professor" and take what he says seriously.Zack didn't know anything about Butz, but could have researched his background. If Zack ran a search for "Arthur Butz," on the search engine Google, he would find Butz's name on a page titled "Holocaust Deniers" at the Web site for the anti-hate organization HateWatch (http://www.spl-center.org/intel/hatewatch/). Similarly, Zack would find Butz's article at a second hate directory site listed under "A Guide to Hate Groups on the Internet: Hate Books, Newsletters and Articles". Zack would find Butz mentioned negatively in a March 1998 USA Today article titled, "College anti-Semitism on the rise, according to new report." Zack would also find Butz's book described as popular among "anti-Semites" in a review of Deborah Lipstadt's book Denying the Holocaust.If Zack had run this multi-search on Butz, he would have seen how other people categorize Butz' work.Establish the credibility of the author. Meta-Web Information Meta-Web information validates Web pages solely within the context of other Web pages.Let's start with the URL, or address, of a Web page. You need to know when they're accessing a personal home page. Most Internet Service Providers give their subscribers a few megabytes of free space on a Web server to use as they want.Here are two sample URLs: and stefan/>. An experienced Web user knows that both URLs point to personal home pages.In the first example, the word "users" is the user name of someone who accesses the Internet through cdsinet.net. In the second example, focus on the . A tilde () indicates a Web site that has been created by someone given space on a Web server. "stefan" is the user name of someone who accesses the Internet through icon-stl.net.Knowing the above, if Zack had looked at Butz's URL - abutz/index.html> – he'd have seen the , an indicator that this is a personal Web site. Just as Zack can know something about individuals by their clothing, he can learn about a Web site by looking at its URL. Clothing tells us a lot, but the company a person keeps tells us more. Learning how a Web page interacts within the network of all other Web sites is valuable information.Meta-information sources.It is always a good idea to look beyond the Internet for sources of authentic information.evaluate [ɪ'væljυeɪt] (v) оценивать; определять количество, качество и т. п.technique [tek'ni:k] (n) метод; способdetermine [dɪ'tɜ:mɪn] (v) определять; устанавливатьentertain [̗entə'teɪn] (v) развлекать, заниматьadvocacy ['ædvəkəsɪ] (n) 1) защита2) пропаганда (взглядов и т. п.)distinguish [dɪ'stɪŋɡwɪʃ] (v) различать, распознаватьauthoritative [ɔ:'θɒrɪtətɪv] (adj) авторитетный; надёжныйdeny [dɪ'naɪ] (v) отрицать, отвергатьdenier тот, кто что-либо отвергаетcredibility [̗krədə'bɪlətɪ] (n) вероятность, правдоподобиеexperienced [ɪk'spɪərɪənst] опытный, знающийtilde ['tɪldə] (n) (полигр.) тильда (tilde)beyond [bɪ'jɒnd] (prep) за; по ту сторону, внеauthentic [ɔ:'θentɪk] (a) 1) подлинный, аутентичный2) достоверный, верный4.14. Translate the text into English and then finish it. Use the vocabulary from the Texts B,C.Все большее количество студентов используют Интернет как источник информации для своих исследований. Сегодня в Интернете можно найти доказательства любых идей, которые могут прийти вам в голову. А ведь многие считают ту информацию, которая представлена в Интернете вполне достоверной. Но это не так. Поэтому очень важно научиться оценивать достоверность такой информации.

6.6. Read the text and complete the diagram describing the classification of engineering materials.

Engineering Materials

Engineers have to know the best and most economical materials to use. Engineers must also understand the properties of these materials and how they can be worked. There are two kinds of materials used in engineering – metals and non-metals. We can divide metals into ferrous and non-ferrous. The former contain iron and the latter do not contain iron. Cast iron and steel, which are both alloys, or mixtures of iron and carbon, are the two most important ferrous metals. Steel contains a smaller proportion of carbon than cast iron. Certain elements can improve the properties of steel and are therefore added to it. For example, chromium may be included to resist corrosion and tungsten to increase hardness. Aluminium, copper, and the alloys (bronze and brass) are common non-ferrous metals.

Plastics and ceramics are non-metals; however, plastics may be machined like metals. Plastics are classified into two types – thermoplastics and thermosets. Thermoplastics can be shaped and reshaped by heat and pressure but thermosets cannot be reshaped because they undergo chemical changes as they harden. Ceramics are often employed by engineers when materials which can withstand high temperatures are needed.
