1. THE INTERNET originated in the early 1970s when the United States wanted
to make sure that people could communicate after a nuclear war. This needed a
free and independent communication network without a centre and it led to a
network of computers that could send each other e-mail through cyberspace.
2. Tim Berners-Lee invented the World Wide Web (WWW) when he discovered a
way to jump to different files on this computer using the random, or
unplanned, links between them. He then wrote a simple coding system, called
HTML (Hyper Text Markup Language), to create links to files on any
computer connected to the network. This was possible because each file had an
individual address, or URL (Uniform Resource Locator). He then used a set of
transfer rules, called HTTP (Hyper Text Transfer Protocol), to link Web files
together across the Internet. Berners-Lee also invented the world's first browser.
This lets you locate and view Web pages and also navigate from one link to
110
another.
3. The WWW became available to everyone in 1991 and the number of Internet
users grew from 600,000 to 40 million in five years. Today, that number is
much larger and there are now many browsers that provide Web pages,
information and other services. You can also do research, download music files,
play interactive games, shop, talk in chat rooms and send and receive e-mail on
the WWW.

SCHOOLING OF THE FUTURE (additional work on futureprediction)
1) Leia o texto Schooling of the future e responda à seguinte pergunta:
a) O narrador é a favor ou contra os desenvolvimentos mencionados?
Schooling of the Future
1. In the near future all schools and libraries will be linked together to form a National
Grid for Learning – just like the electricity grid which connects all consumers. Each
pupil will have a palmtop linked to the school network and to the Internet. All pupils
from the age of nine will have email accounts.
2. All communications between the Department for Education and schools will be by
computer links. Learning and administration will be paper-free. The advantages are
obvious. Pupils will have access to a world of learning. The resources available
through the Grid will be greater than any one school can provide.
3. In addition, all pupils will become familiar with information technology at an early
stage in their school life. Their computer skills will help them when they leave school
and enter college or go into work. All study and most jobs in the future will require
computer literacy. These developments will equip our pupils for an IT-based future.
4. Email will allow pupils to communicate easily with other pupils in different parts of
the country and in different parts of the world. It will develop communications skills
and encourage an international outlook.
5. Finally, by freeing teachers from paperwork, IT will give them more time for their
real job of inspiring students.
2) Leia o texto novamente e responda se as sentenças são falsas ou verdadeiras. Indique
em que parágrafo e linha você encontrou a resposta:
a) Os estudantes terão acesso a um mundo de conhecimento porque todos terão um
palmtop conectado com a rede escolar e a Internet.
115
b) Os estudantes estarão familiarizados com a TI a partir da adolescência.
c) Quando os alunos chegarem à faculdade ou ao mercado de trabalho não terão
dificuldade com a informática.
d) As habilidades de comunicação dos estudantes serão aperfeiçoadas por meio dos
video games.
e) Os professores terão mais trabalhos para corrigir.
3) Relacione as palavras da primeira coluna à sua definição na segunda:
a) allow (v)
a) a place where books, documents, CDs
b) available
etc are available for you to look at or
c) account

I-Aquecimento (Warm-up)
1) Qual é o melhor lugar para encontrar informações sobre os seguintes tópicos:
European history
the price of mobile phones
our favourite pop star
2) Quais são as vantagens e desvantagens de procurar informações nas seguintes
fontes:
books
magazines
newspapers
libraries
encyclopaedias
friends or family
teachers
CD-ROMs
television
radio
the Internet
3) Leia o texto rapidamente e escolha a resposta correta.
a) Google is a keyword / search engine.
b) This WORD is in upper / lower case.
c) AND / WHEN is a logical operator.
1. Finding information on the World Wide Web needs an Internet search engine such
as Google, Alta Vista or Yahoo. Search engines have a text box where you type in a
keyword or words. A search engine is a software program that reads the keywords in
the text box and searches the Internet for web pages, Websites, and other Internet files
that use them. These documents are shown on the computer screen in a results listing.
2. When carrying out searches, you should usually be specific and brief in your choice
of words. If the keyword is too general, or includes too many different meanings, the
results listing may not be useful. Different search engines categorize information in
different ways, which changes the way they store and retrieve it.
3. Using upper case letters (capital letters) in a keyword search will only retrieve
documents that are upper case. Typing in lower case (no capitals) is usually better
117
because search engines will retrieve documents that use both upper case and lower case
letters.
4. You can narrow a search engine using logical operators such as AND, OR and NOT.
AND retrieves all the words typed in the text box, OR retrieves either of the words and
NOT excludes words. Spelling is important when typing in keywords, but a search
engine will not usually read punctuation, prepositions, and articles.
4. Abaixo você encontrará instruções sobre o que deve e o que não deve ser feito
quando se procura informações na Internet. Assinale as instruções que você
considera adequadas.
a) Escolha palavras que são diferentes do item que você quer. ____________
b) Dê a palavra-chave mais adequada para descrever o que você quer. ___________
c) Use várias palavras-chave. ________________________________
d) Tente usar uma palavra-chave que tenha somente um significado. __________
e) Digite suas palavras-chave somente em letras minúsculas._______________
f) Use operadores lógicos para delimitar sua pesquisa. __________________
g) Use ponto final e vírgula. _________________________
h) Não use palavras como AT, IN, ON, A/AN e THE. _____________________
5. Encontre palavras e expressões no texto que signifiquem:
a) claro e exato (§ 2) ______________________________________________
b) colocar em grupos semelhantes (§2) ________________________________
c) recuperar, trazer de volta (§2) _________________________________________
d) diminuir, limitar, delimitar (§4) ______________________________________
e) palavras matemáticas (§4) ____________________________________
6) Encontre no texto duas sentenças com verbos modais que indicam:
a) Previsão para o futuro _____________________________________________
b) Conselho_________________________________________________________
7) Encontre no texto um adjetivo comparativo irregular: ______________________

 The abacus was invented and was used until the 16th century.
 It is still used today in some parts of the world to make arithmetical
calculations.
III-Que regra para a formação da voz passiva você pode deduzir a partir dos dois
exemplos?
IV-Você percebe alguma diferença no modo de formação da voz passiva entre o
português e o inglês?
Informações gerais sobre a voz passiva e ativa:
1. Usamos a voz ativa quando queremos enfatizar tanto o agente quanto a ação: A
police officer requests records of a suspect.
2. Quando queremos enfatizar mais a ação do que o agente, ou quando é bem claro
quem ou o que é o agente, usamos a voz passiva: Records of a suspect are requested.
3. Formamos a voz passiva usando o verbo TO BE (presente)+o particípio passado do
verbo principal (-ed para verbos regulares e a 3ª coluna para verbos irregulares).
4. Para outros tempos verbais, quem define o tempo é sempre o verbo TO BE. Por
exemplo:
a) The computer was fixed by a good technician.
b) The computer can be fixed by my father.
c) The computer will be fixed by my father.
d) The computer should be fixed by my father.
.....

1. The Java platform is based on the power of networks and the idea that the same
software should run on many different kinds of computers, consumer gadgets, and other
devices. Since its initial commercial release in 1995, Java technology has grown in
popularity and usage because of its portability. The Java platform allows you to run the
same Java application on lots of different kinds of computers. Any Java application can
124
easily be delivered over the Internet, or any network, without operating system or
hardware platform compatibility issues. For example, you could run a Java technology
based application on a PC, a Macintosh computer, a network computer, or even new
technologies like Internet screen phones. Furthermore, the Java platform was designed
to run programs securely on networks, which means that it integrates safely with the
existing systems on your network.
2. The idea is simple: Java technology-based software can work just about everywhere.
Java technology components don't care what kind of computer, phone, TV, or operating
system they run on. They just work on any kind of compatible device that supports the
Java platform.
3. Java technology allows programmers and users to do new things with Web pages that
were impossible before. With Java technology, the Internet and private networks
become your computing environment. For example, users can securely access their
personal information and applications when they're far away from the office by using
any computer that's connected to the Internet; soon they'll be able to access tailored
applications from a mobile phone base on the Java platform, or even use smart cards as
a pass key to everything from the cash machine to ski lifts.
4. The Java platform is being built into next-generation telephones, TV set-top boxes,
smart cards that fit in your wallet, and many other consumer and business devices. Java
technology-based software includes: programs written in the Java programming
language can run directly on your computer (without requiring a browser), or on
servers, on large mainframe computers, or other devices.
5. For example, Java technology-based software running on servers in large companies
monitors transactions and ties together data from existing computer systems. Other
companies are using Java technology-based software on their internal Web sites to
streamline communication and the flow of information between departments, suppliers
and customers.

ESTUDO DIRIGIDO - PAIR WORK
I-Leia o texto e responda e responda às perguntas que seguem abaixo:
Phishing
In the field of computer security, phishing is the criminally fraudulent process of
attempting to acquire sensitive information such as usernames, passwords and credit
card details by masquerading as a trustworthy entity in an electronic communication.
Communications purporting to be from popular social web sites, auction sites, online
payment processors or IT administrators are commonly used to lure the unsuspecting
public.
Phishing is typically carried out by e-mail or instant messaging and it often directs users
to enter details at a fake website whose look and feel are almost identical to the
legitimate one. Even when using server authentication, it may require tremendous skill
to detect that the website is fake. Phishing is an example of social engineering
techniques used to fool users and exploits the poor usability of current web security
technologies. Attempts to deal with the growing number of reported phishing incidents
include legislation, user training, public awareness, and technical security measures.
A phishing technique was described in detail in 1987, and the first recorded use of the
term "phishing" was made in 1996. The term is a variant of fishing probably influenced
by phreaking, and alludes to baits used to "catch" financial information and passwords.
