We are becoming increasingly dependent on computers. They are used in businesses, hospitals, crime detection and even to fly planes. What things will they be used for in the future? Is this dependence on computers a good thing or should we be more suspicious of their benefits?

Computers are a relatively new invention. The first computers were built fifty years ago and it is only in the last thirty or so years that their influence has affected our everyday life. Personal computers were introduced as recently as the early eighties. In this short time they have made a tremendous impact on our lives. We are now so dependent on computers that it is hard to imagine what things would be like today without them. You have only got to go into a bank when their main computer is broken to appreciate the chaos that would occur if computers were suddenly removed world-wide.

In the future computers will be used to create bigger and even more sophisticated computers. The prospects for this are quite alarming. They will be so complex that no individual could hope to understand how they work. They will bring a lot of benefits but they will also increase the potential for unimaginable chaos. They will, for example, be able to fly planes and they will be able to co ordinate the movements of several planes in the vicinity of an airport. Providing all the computers are working correctly nothing can go wrong. If one small program fails disaster.

There is a certain inevitability that technology will progress and become increasingly complex. We should, however, ensure that we are still in a position where we are able to control technology. It will be all too easy to suddenly discover that technology is controlling us. By then it might be too late I believe that it is very important to be suspicious of the benefits that computers will bring and to make sure that we never become totally dependent on a completely technological world.

Nowadays food has become easier to prepare. Has this change improved the way people live?

Food is a basic part of life, so it follows that improved methods of food preparation have made our lives better. Nowadays we can prepare meals much faster than we could in the past. We can also enjoy a greater variety of food and eat more healthfully, all because of modern methods of food preparation.

Microwave ovens have made it possible to prepare delicious food quickly. People these days rarely have time to shop and prepare meals the old-fashioned way. We live very fast lives. We are busy working, caring for our families travelling, playing sports, and many other things. Because of microwave ovens, we have time to enjoy a good meal with our family and then play soccer, go to a movie, study, or do anything else we want to afterwards.

Modern methods of preserving food have made it possible to enjoy a wide variety of food. Because of refrigerators, freezers, canning, and freeze-drying, we can eat fruits and vegetables that come from far away places. We can prepare a meal one day and save the leftovers in the refrigerator or freezer to eat at another time. We can keep different kinds of food in the refrigerator. It is easy to always have food available and to be able to eat completely different meals every day.

Healthful eating is easier now than it ever was. Because of modern transportation methods, fresh fruits and vegetables are available all year round. Modern kitchen appliances make it easy to prepare fruits and vegetables fro cooking. Bread machines make it possible to enjoy healthful, home-baked bread whenever we like. We can eat fresh and healthful food everyday because modern methods have made preparation easy.

Our lifestyle is fast, but people still like good food. New food preparation methods have given us more choices. Today we can prepare food that is more convenient, healthier, and of greater variety than ever before.

When a country develops its technology, the traditional skills and ways of life die out. It is pointless to try and keep them alive.
To what extent do you agree or disagree with this opinion?

Overall, I disagree with the opinion expressed, I would like to begin by pointing out that ‘traditional skills and ways of life’ are not automatically of one country, but of a culture or community.

In many ways, the history of civilisation is the history of technology: from the discovery of fire to the invention of the wheel to the development of the Internet we have been moving on from previous ways of doing things. Some technologies, such as weapons of mass destruction, are of negative impact. Others, such as medical advances, positively help people to live better or longer, and so very much help traditional ways of life. Surely, few people would seek to preserve such traditions as living in caves.

Interestingly, technology can positively contribute to the keeping alive of traditional skills and ways of life. For example, the populations of some islands are too small to have normal schools. Rather than breaking up families by sending children to the mainland, education authorities have been able to use the Internet to deliver schooling online. In addition, the Internet, and modern refrigeration techniques, are being used to keep alive the traditional skills of producing salmon; it can now be ordered from, and delivered to, anywhere in the world.

In conclusion, without suggesting that all technology is necessarily good, I think it is by no means ‘pointless’, in any way, to try to keep traditions alive with technology. We should not ignore technology, because it can be our friend and support our way of life.

In the last 20 years there have been significant developments in the field of information technology (IT), for example the World Wide Web and communication by email. However, future developments in IT are likely to have more negative effects than positive.

To what extent do you agree with this view?

The last two decades have seen enormous changes in the way people's lives are affected by IT. Twenty years ago few people had access to a computer whilst today most people use them at work, home or school and use of email and the Internet is an everyday event.

These developments have brought many benefits to our lives. Email makes communication (particularly overseas) much easier and more immediate. This has numerous benefits for business, commerce and education. The World Wide Web means that information on every conceivable subject is now available to us. Clearly, for many people this has made life much easier and more convenient.

However, not all the effects of the new technology has been beneficial. Many people feel that the widespread use of email is destroying traditional forms of communication such as letter writing, telephone and face to face communication. With ever increasing use of information technology these negative elements are likely to increase in the future.

The huge size of the Web means it is almost impossible to control and regulate. This has led to many concerns regarding children accessing unsuitable websites. Unfortunately, this kind of problem might even get worse in the future at least until more regulated systems are set up. Yet perhaps the biggest threat to IT in years to come will be the computer virus – more sophisticated or more destructive strains are almost inevitable.

In conclusion, developments in IT have brought many benefits, yet I believe developments relating to new technology in the future are likely to produce many negative effects that will need to be addressed very carefully.

We have been living in the nuclear age now for over half a century. Since the first atomic bombs were developed, nuclear technology has provided governments with the ability to totally destroy the planet. Yet the technology has been put to positive use as an energy source and in certain areas of medicine.

To what extent is nuclear technology a danger to life on Earth? What are the benefits and risks associated with its use?

These days, many people are afraid of nuclear technology because of the dangers associated with its use. In my opinion, although it is true that nuclear weapons pose the greatest threat to life, the use of nuclear technology for peaceful purposes also carries some serious risks.

Nuclear power stations provide an important source of cheap power for many industrialised nations and some developing countries. However, there is always the danger of radiation leaking from these plants. Even though safety precautions are taken, there have been numerous disasters such as the explosion of a nuclear plant in Russia not long ago.

Nuclear technology is even used to help cure some diseases such as cancer. Radiation can be applied to the body to burn away cancerous cells. This is, however, a dangerous procedure, and the application of radiation is almost always painful and not always successful.

The most worrying aspect of nuclear technology, though, is its use for military purposes. Enough atomic bombs have already been built to completely destroy the planet, and the real danger is that one day some country will start a war with these weapons. Too many countries now have the technology required to make such bombs, and there is currently much debate about how to control the situation.

In conclusion, nuclear technology certainly has positive uses, but is, nonetheless, dangerous. However, it would have been better if it had never been used to create nuclear weapons. If life on Earth is to continue, all the nuclear nations of the world should agree to disarm as soon as possible.
