Ex. 3. Прочитайте та перекладіть текст: COMPUTERS Computer is an electronic device that can receive a set of instructions called program and then carry out them. The modern world of high technology could not be possible without computers. Different types and sizes of computers find uses throughout our society. They are used for the storage and handling of data, secret governmental files, information about banking transactions and so on. Computers have opened up a new era in manufacturing and they have enhanced modern communication systems. They are essential tools in almost every field of research, from constructing models of the universe to producing tomorrow's weather reports. Using of different databases and computer networks make available a great variety of information sources. There are two main types of computers, analog and digital, although the term computer is often used to mean only the digital type, because this type of computer is widely used today. That is why I am going to tell you about digital computers. Everything that a digital computer does is based on one operation: the ability to determine: on or off, high voltage or low voltage or - - in the case of numbers - - 0 or 1 or do-called binary code. The speed at which the computer performs this simple act is called computer speed. Computer speeds are measured in Hertz or cycles per second. A computer with a «clock speed» of 2000 MHz is a fairly representative microcomputer today. It is capable of executing 2000 million discrete operations per second. Nowadays microcomputers can perform from 800 to over 3000 million operations per second and supercomputers used in research and defense applications attain speeds of many billions of cycles per second. Digital computer speed and calculating power are further enhanced by the amount of data handled during each cycle. Except two main types of computers, analog and digital there are eight generations of digital computers or processing units. The first generation was represented by processing unit Intel 8086. The second generation central processing unit was represented by processing unit Intel 80286, used in IBM PC AT 286. The third generation is Intel 80386, used in IBM PC AT 386. The microprocessors of the fourth generation were used in computers IBM PC AT 486. There are also central processing units of the fifth generation, used in Intel Pentium 60 and Intel Pentium 66, central processing units of the sixth generation, used in computers Intel Pentium 75, 90, 100 and 133. Few years ago appeared central processing units of seventh and eighth generations. They are much more powerful and can perform from 2000 to over 3000 million operations per second.

Ex. 2. Прочитайте та перекладіть текст:
How it works - The Internet
The Internet is an incredibly large number of separate, local computer networks (LANs -Local Area Networks), online services, newsgroups and e-mail addresses all interconnected by the global telephone network. The network consists of a hierarchy of high-capacity lines connected by exchanges. Figure 1 shows the different types of lines and their frequencies.
Figure 1: Operating frequencies for lines and how long they would take to transmit the complete 33-volume Encyclopedia Britannica. To access the Internet, you need a modem or ISDN adapter to convert the digital data into a format suitable for the telephone lines. The data is broken down into small packages which can be sent and then assembled again by another computer. The method the software uses to do this is called a 'protocol'.
Obviously, with so many different computer systems on the market there are many different protocols, which have to be converted if all of the Net users are to be compatible. Next, you have to subscribe to either an Internet Service Provider (ISP) or an online service. These companies lease continuously open, high-capacity telephone lines to send the information to the subscriber's computer. The subscriber pays the ISP a flat rate per month and/or an hourly online charge (not including the telephone charges for connection to the ISP). It's important that your ISP has a local connection (PoP - Point of Presence), otherwise your online telephone charges will be at long distance rates. Online services, such as CompuServe, America Online (AOL) or T-Online, are actually services providing news, magazines, chat forums, e-mail and entertainment, and are not really part of the Internet. However, all of them now offer their customers access to the Net as well. Perhaps the most well-known network on the Internet is the World Wide Web (WWW). The Web uses its own HTTP (Hypertext Transfer Protocol) format which enables sophisticated graphics to be transmitted at high-speed. Almost every major company is now on the Web, which is growing at a rate of about 1,000 new sites a month.

There are more than 4,000 periodical editions in Ukraine now, and new radio and TV channels, newspapers and magazines appear practically every year. The role of mass media in our everyday life is enormous. Where do we get most of the news? From TV or radio news programmes, or from newspapers. What forms public opinion? Mass media. So they bear great responsibility and should always give truthful and unbiased information to their readers and viewers. In Ukraine there are several information agencies that supply the population of the country with the latest news. These agencies are: the "UKRINFORM" - "Ukrainian National Information Agency", the "UNIAR" — "The Ukrainian Independent Information Agency "Respublica", the UNIAN — the Ukrainian Independent News Agency Interfax- Ukraina" and some others. These agencies have reporters in every administrative region of our country and in all major foreign countries. They collect most interesting and important information for the readers of newspapers and magazines and for the TV viewers.
There are newspapers and magazines for the readers of all ages and professions, with different interests, tastes and hobbies. For example, those who are interested in politics can read the newspapers "Day", "Today", "Facts", "Grany", "Kyivsky Vidomosty". In these newspapers the readers can also find information about home affairs, culture and sports. These publications deal with the burning problems of our present life and history, and at the same time there you can find amusing stories, crosswords and puzzles that can entertain you in your spare time. Enthusiastic sports fans of Ukraine like the newspapers "Sportyvna Gazeta" and "Komanda" (The Team"). There is a special newspaper for those who live in the country and are interested in farming — "Silske Zhutya" ('The Rural Life"). Doctors, nurses and people who are interested in medicine prefer reading the "Medical Newspaper". There are also magazines for businessmen and businesswomen, for scientists and gardeners, etc. Those who like to learn about the new publications in literature can read the magazines "Dnipro" and "Vsesvit". Teachers have their own newspaper "Vchitelska Gazeta", and specialists of different subjects can buy journals in their special fields. Young people like to read the newspapers "Kosa", "Artmozaica", "Telenedelya" and others. Some people buy newspapers and magazines every day, others prefer to subscribe to them, and in this case these periodicals are delivered to their homes. Payment for a subscription to newspapers and magazines is accepted at every post-office. Ukrainian learners of English can find a lot of interesting information in the newspapers and magazines published in English — "Kyiv Post", "News from Ukraine", "Digest". Some magazines are published every month, and they are called monthlies; if they are published every 3 months, they are called quarterlies. Newspapers are usually published daily or weekly. Television and radio networks in Ukraine are divided into government-run companies and private TV and radio companies. The State TV and Radio Company operates two channels and includes editorial services that specialize in political analysis, socio-political programmes, current information, youth and sports programmes. Private channels tend to broadcast music and news programmes, a lot of advertising and talk shows.

Б) З сусідом по парі обговоріть, з якими з цих тверджень ви погоджуєтес,ь а з яким ні. What do you think? I. A: I hate watching TV. It's such a waste of time, and most of the programs are quite boring. B: Really? I love TV. I watch quite a lot for relaxation — and I've learnt quite a lot from TV, too. II. A: Do you think Jimmy should be watching that program at his age? So much violence can't be good for adults, let alone youngsters. B: Oh, I don't know. Even kids can tell the difference between TV and real life. ІІІ. A: I don't buy a newspaper every day, but I like to read one whenever something important has happened: it's better than TV or the radio. B: I never buy them. You can't believe half of what you read. IV. I don't read newspapers at all. They are all biased. They've been taken over by companies who have political interests. And in Britain most of the papers are right-wing. There are one or two that I think are a bit more objective, but I'd rather listen to the radio. V. Actually, I don't want to know about the details of all the troubles in the world — it's all so depressing. I like human interest stories — stories about people, not wars and disasters. So my daily news paper is a tabloid. The other good thing about a tabloid is that you can read it in ten minutes on the way to work. That's all I want. VI. 1 get a so-called quality newspaper on Sundays because it gives me a good summary of world events, but I also buy tabloids two or three times a week. People are critical of the pictures and stories of the royals and their problems that have been published in the tabloids, but I don't agree. Why shouldn't we know how we are spending our money? They are public figures, and only the tabloids give you Ex. 3. Прочитайте та перекладіть текст: Television in Modern Life How do people usually answer the question like, "What are your plans for tonight?" or "What are you doing at the weekend?" In other words, how do people spend their free time? Some tventy or thirty years ago the usual answers used to be: "We are going to the theatre (or the cinema)" or "We are going to a party" or "We are having some friends round". Now you quite often hear, "We are going to stay at home and watch the telly." Television (colloquially known as TV or telly) is now so popular in the whole world that it is hard to believe that it appeared only about fifty years ago. A first-rate colour TV set has become an ordinary thing in the household today, and a video cassette recorder (VCR) is quickly becoming one. Modern television offers the viewers several programs on different channels. In addition to regular news programmes, you can see plays and films, operas and ballets, and watch all kinds of contests, quizzes, soap operas, serials and sporting events. You can also get a lot of useful information on the educational channel. A good serial (perhaps, a detective story or a screen version of a classical novel) can keep the whole family in front of the telly for days, and don't we spend hours and hours watching out favourite football or hockey team in an important international event? Television most definitely plays an important part in people's lives. But is it a good thing or a bad one? Haven't we become lazier because of the television? Don't we go out less often? Don't we read less? And yet a lot of people believe that the telly has made our life more interesting and can't imagine their everyday life without it. Ex. 4.

A major such venue of the 18th century was Kyiv Mohyla Academy. In the 19th c the universities of Kyiv, Kharkov, Odessa, and Lviv became noted research centers where the first national schools of science took shape. Much credit in the development of Ukrainian science is due to M. Ostrohradsky (mathematics), O. Bodiansky (linguistics), V. Antonovych (history), M. Maksymovych (ethnography and plant physiology), V. Obraztsov, F. Yanovsky, V. Karavaiev, O. Bets, M. Strazbesko, M. Volkovych, and V. Filatov (medicine). The creation of Ukrainian Academy of Sciences in 1918 was an event of historic import. Among its founding members were V. Vernadsky, a famous 20th c scientists and naturalists; noted historians M. Hrushevsky and D. Bahalii; orientalist A. Krymsky; mechanics expert S. Tymoshenko; lawyer M. Vasylenko and many others. Associated with the Academy are the names of outstanding scientists, among them physician and mathematician M. Boholyubov, biologist M. Kashchenko, microbiologist and epidemiologist D. Zabolotny, botanists Ye. Votohal, O. Fomin, M. Kholodny, archaeologist and etnographer M. Biliashivsky, zoologist I. Sclumalhauwn, economist K. Vobly, and demographer M. Ptuhka. World-reputed schools schools appeared, headed by D. Hrave (algebra), M. Krylov (mathematical physics), Ye. Paton (electric welding and bridge construction), L. Pysarzhevsky (chemistry), O. Dynnyk (mechanics and elasticity theory), O. Bohomolets (experimental pathology). At present, the National Academy of Sciences comprises 170 researches centers with powerful research-and-productive facilities. All told, there are some 3,500 Doctors and 10,000 Candidates of Science. There are 208 Academicians and 280 Corresponding members, plus 81 foreign members from 18 countries, including the USA, France, Germany, the UK, Italy, and Japan. The National Academy of Ukraine ranks with Europe’s leading scientific venues. Among its attainments are outstanding accomplishments in natural history and technology, along with tangible contributions to sociology and the humanities. Since 1962 its President has been Boris Paton, a noted scientist, organizer, honorary member of academies in many countries. A great deal has been done in the leading sciences over the past several years. Thus, the world’s first laser data shortage came as the result of complex developments by experts of informatics, physics, physical metallurgy and chemistry. World priorities have a number of achievements in machine building, rocket and computer technology, molecular biology, genetic engineering, microbiology and medicine. The National Academy of Ukraine maintains and expands international contacts with academies and research associations and centers in many countries.

Ex. 3. Прочитайте та перекладіть текст: COMPUTERS Computer is an electronic device that can receive a set of instructions called program and then carry out them. The modern world of high technology could not be possible without computers. Different types and sizes of computers find uses throughout our society. They are used for the storage and handling of data, secret governmental files, information about banking transactions and so on. Computers have opened up a new era in manufacturing and they have enhanced modern communication systems. They are essential tools in almost every field of research, from constructing models of the universe to producing tomorrow's weather reports. Using of different databases and computer networks make available a great variety of information sources. There are two main types of computers, analog and digital, although the term computer is often used to mean only the digital type, because this type of computer is widely used today. That is why I am going to tell you about digital computers. Everything that a digital computer does is based on one operation: the ability to determine: on or off, high voltage or low voltage or - - in the case of numbers - - 0 or 1 or do-called binary code. The speed at which the computer performs this simple act is called computer speed. Computer speeds are measured in Hertz or cycles per second. A computer with a «clock speed» of 2000 MHz is a fairly representative microcomputer today. It is capable of executing 2000 million discrete operations per second. Nowadays microcomputers can perform from 800 to over 3000 million operations per second and supercomputers used in research and defense applications attain speeds of many billions of cycles per second. Digital computer speed and calculating power are further enhanced by the amount of data handled during each cycle. Except two main types of computers, analog and digital there are eight generations of digital computers or processing units. The first generation was represented by processing unit Intel 8086. The second generation central processing unit was represented by processing unit Intel 80286, used in IBM PC AT 286. The third generation is Intel 80386, used in IBM PC AT 386. The microprocessors of the fourth generation were used in computers IBM PC AT 486. There are also central processing units of the fifth generation, used in Intel Pentium 60 and Intel Pentium 66, central processing units of the sixth generation, used in computers Intel Pentium 75, 90, 100 and 133. Few years ago appeared central processing units of seventh and eighth generations. They are much more powerful and can perform from 2000 to over 3000 million operations per second. Ex. 4.
