Procedure

I.      Introduction

T: today our topic is ‘Computer: pros and cons’. As far as I know, you have been discussing the problems of computer science in Information Technology lessons.

Be ready to discuss advantages and disadvantages of computer technologies. But first answer the following questions.

Can you have PC at home?

Can you use it?

Can you use the Internet?

What do you use the Internet for?

Do you enjoy working on computer? Why?

 

Sample answer

Computers can do a lot of work for us. They help us at school. They store useful information. Besides, they can teach us English as well as other subjects. On the other hand, computer users face up many problems. Computer viruses are a headache for many users.

You shouldn’t spend too much time at your PC. It’s bad for your eyesight.

T: And now switch on your computers.

 

II.  Warm-up

(Pupils are given stars with adjectives denoting their state of mood.)

 

T: Now you work in pairs. Student A feels pessimistic and Student B feels optimistic. Make optimistic and pessimistic predictions about the future of the Net in thirty years.

 

Possible answers:

S1: I’m optimistic about the future of the Net. Users can buy books, find out about holiday offers, book tickets and get all sorts of information in the Net.

S2: You will be able to work from home, or ‘telecommute’, in other words you’ll have an access to video-conferencing.

S3: Schoolchildren will benefit enormously since they will be able to communicate with other classes, teachers and experts thousand miles away. Everyone will be able to use on-line libraries.

S4: To my mind, the Net will not only help in providing remote electronic banking, teaching, shopping, tax-paying, game playing, video-conferencing or film ordering but we’ll also receive medical help from it. No doubt, it’ll be fantastic.

S5: If we didn’t have computer addicts, we wouldn’t have modern technologies. They are inventors of tomorrow.

S6: I’m confused. Yes, but what did we use before there was a computer? The computer hasn’t been with us all that long, but we already forget what the world was like without it.

S7: Many parents worry that computer addiction will make their children unfriendly and unable to communicate with people.

S8: Whole generations are growing up addicted to the Net. Food is left uneaten, homework undone and sleep is lost.

Little by little, computers cut us off from the real world. We get so lazy, we choose to spend a fine day in semi-darkness, glued to our computers screen, rather than go out into the world itself.

S9: I’m sure some scientists and experts are pessimistic about the future. They worry about cyber crimes. Even now, young hackers can get into computers of banks and governmental organizations. In the future, cyber terrorism may ‘attack’ the world’s computers, cause chaos and plane and train crushes.

While listening

T: Listen to the text and check your answers

Tapescript

Presenter: Welcome to ‘Future Now’. Today we are going to discuss the Internet with Dr Jennifer May from Manchester University. Dr May, how did the Internet begin?

Dr May: Well, it’s strange but the Internet was started by the military. In 1969, the Pentagon thought of linking computers into a network so that if one part of the network was destroyed in the nuclear war, other parts could continue working.

Presenter: And then scientists started to use the network, right?

Dr May: Yes, people in universities all over the world began to use the network to share ideas. They used it for work and for fun. In the 1980s, people started calling it the Internet.

Presenter: Then it was in the mid-1990s that the Internet really began to grow fast.

Dr May: Yes, now the Internet is important for entertainment, e-mail, playing games and getting information.

While reading

T: The groups will be given parts of the scrambled text. You have to rearrange them in a logical order and then read the text.

THE SYMPTOMS OF INTERNET ADDICTION

A. An international group of psychologists has recently suggested that anyone who surfs the Internet for long period is clinically ill and needs medical treatment.

According to their report, Internet addicts should be treated in the same way as alcoholics, drug addicts, compulsive gamblers and people with eating disorders.

B. Understandably, his parents are extremely worried. Not only has his school work suffered, but Russel’s addiction has also destroyed his social life and his spare-time interests. For instance, he has just dropped out of his school’s basketball team in order to spend more time at his computer.

C. Instead of spending next weekend having a good time out with friends, he’ll be spending it indoors surfing the Internet. Russel has recently joined an Internet online support group. It may seem ironic that many of the support groups for the Internet addicts are online but at least Russel has sought help. Not everyone does.

D. Last week, in a private rehabilitation clinic outside Edinburgh, Loe Edwards, a sixteen-year-old schoolboy, was going through severe withdrawal symptoms. His body often shook violently and uncontrollably, and at mealtimes he regularly threw cups and plates around the dining room.

The boy’s addiction had nothing to do with alcohol, drugs, gambling or food. His problem was “Net obsession” – an over-dependency on the Internet.

E. Dr Ann Hoffman, who runs an online support groups, says, ‘People don’t realize that being online for more than four hours a day amounts to addiction and that they have a serious problem. I predict that the number of people who join online support groups will have risen dramatically within three years’.

F. Leo Edwards is not an isolated case. Russel Hopkins, aged fifteen, from Gateshead in northeast England, is a typical online addict. Every day after school dinner until three or four in the morning, he will be found in his room surfing the Net or playing computer games. By the end of the day he will have spent more than six hours online.

Key: 1-d, 2-a, 3-f, 4-b, 5-c, 6-e.

 

Post-reading

T: Answer the questions.

1.     How did Leo respond to withdrawal from the Internet?

2.     What do some psychologists compare Internet addicts to?

3.     Is Russel a typical Internet addict?

4.     What two things has he stopped doing?

5.     What does Dr Hoffman predicts?

Key:

1.     His body shook and he threw cups and plates around.

2.     Alcoholics, drug addicts, compulsive gamblers and people with eating disorder.

3.     Every day he surfs the Net after school and after dinner, until three or four in the morning.

4.     He has stopped playing basketball and he does less school work.

5.     That within three years a lot more people will join online support groups – there will be more Internet addicts.

3. Speaking

T: You are the participant of the Internet online support group. Give your advice on preventing the Internet addiction. What are advantages and disadvantages of using the Internet?

 

Possible answer

Advertisements for the Internet promise you a world of information, entertainment, on-line shopping and e-mail services. However, the real world of the Internet may not be as perfect as the advertisements suggest. Using the Internet offers many advantages. For example, all of the latest information is available for you in your home at any hour of the day or night. It is much faster and easier to surf the net in search of information from all over the world than to travel to libraries of different countries. You’re quite right. On-line shopping makes it possible to search through catalogues to find goods you’d like to buy at the best price, saving both time and money. What is more, by joining a newsgroup or chat group, you can share your special interests with other users, and perhaps make friends all over the world.

Finally, e-mail is popular because it is faster than sending a letter and cheaper than a telephone call.

On the other hand, the Internet has several disadvantages. Firstly, browsing the Internet in search of necessary information might take hours. Multimedia web pages with photographs, music and video are attractive, but they make downloading slow and boring. I agree there is too much advertising instead of real information on the Internet. As for Internet friendships, sitting at home and making ‘chat friends’ online is not the same as actually meeting people.

In conclusion, the Internet obviously has its pros and cons. Fortunately, the system is improving all the time, and any problems which still exist can be solved.

Whether we like it or not, the Internet is here to stay, so we have to make the best of it.
