雅思作文task2范文篇一：

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?

Model Answer:

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.

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 he more auspicious of their benefits?

Model Answer:

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.

As computers are being used more and more in education, there will be soon no role for teachers in the classroom.

Model Answer:

There have been immense advances in technology in most aspects of people's lives, especially in the field of education. Nowadays, an increasing number of students rely on computers to research for information and to produce a perfect paper for school purposes. Others have decided to leave the original way of learning to get knowledge through online schools. These changes in the learning process have brought a special concern regarding the possible decrease of importance of teachers in the classroom.

Some people believe the role of teachers started to fade because computers have been helping some students to progress in their studies quicker than when compared with an original classroom. For example, in the same classroom, students have different intellectual capacities, thus some would be tied to a slow advance in their studies because of others’ incapacity of understanding. In this way, pupils could progress in their acquisition of knowledge at their own pace using computers instead of learning from teachers.

However, the presence of a teacher is essential for students because the human contact influences them in positive ways. Firstly, students realize that they are not dealing with a machine but with a human being who deserves attention and respect. They also learn the importance of studying in group and respect other students, which helps them to improve their social skills.

Moreover, teachers are required in the learning process because they acknowledge some student's deficiencies and help them to solve their problems by repeating the same explanation, giving extra exercises or even suggesting a private tutor. Hence, students can have a bigger chance not to fail in a subject.

In conclusion, the role for teachers in the learning process is still very important and it will continue to be in the future because no machine can replace the human interaction and its consequences.
