Some people consider computers to be more of a hindrance than a help. Others believe that they have greatly increased human potential.
How could computers be considered a hindrance?
Model Answer:
It is easy to understand why some people believe that computers are more of a hindrance than a help. Operations such as obtaining a refund or changing a ticket tend to be fairly straightforward without the aid of a computer, yet once one is involved, the process can become time-consuming, complex and prone to errors. In an office environment, it can sometimes seem that for every hour saved by computers, at least set of problems caused by a system malfunction.
Another consideration is that, over-enthusiastic use of computers in the home has the potential to divert large amounts of free time away from activities such as socialising, tasking exercise or having dinner with your family. Spending a lot of leisure time looking at a computer monitor screen could perhaps achieving other goals in life, such as being healthy and socially integrated.
However, it would be simplistic to assert that computers have a generally negative impact. There have been enormous advences in communications, medicine, design, education and numerous fields of human endeavour. Nowadays, virtually the entire sum of human knowledge is as far away as the nearest internet point. Computers have brought about a profound change in the way most people inthe developed world live. (Although it should not be forgotten that the majority of the inhabitants of this planet have never so much as touched a computer keyboard.)
The benefits of computers undoubtedly outweigh the disadventages. The question is not whethercomputers help or hinder, but whether people always use their huge potential in a sensible and responsible way?

It has been more than 30 years since man first landed on the moon.
Some people think that space research is a waste of money.
Discuss.
Model Answer:
For over fifty years, a number of nations have been involved in the exploration of outer space. This research has been very costly, of course. Has this money been well-spent or wasted?
Some people believe that all or most space research should be eliminated because of its incredible expense, not only in terms of money, but also in terms of scientific and human resources. These people point out the fact that it cost billions of dollars to send astronauts to the moon, but all they brought back were some worthless rocks. These people say that the money and effort now being wasted in outer space could be spent for homeless people, improving the education system, saving the environment, and finding cures for diseases.
However, other people believe that space research has provided many benefits to mankind. They point out that hundreds of useful products, from personal computers to heart pacemakers to freeze-dried foods, are the direct or indirect results of space research. They say that weather and communication satellites, which are also products of space programs, have benefited people all over the globe. In addition to these practical benefits, supporters of the space program point to the scientific knowledge that has been acquired about the sun, the moon, the planets and even our own earth as a result of space research.
I agree with those people who support space research and want it to continue. Space research, as shown, has already brought many benefits to humanity. Perhaps it will bring even more benefits in the future, ones that we can not even imagine now. Moreover, just as individual people need challenges to make their lives more interesting, I believe the human race itself needs a challenge, and I think that the peaceful exploration of outer space provides just such a challenge.

With the increasing popularity of computers and calculators, student literacy is decreasing dramatically. What are the positive and negative effects the progress of science and technology has brought about?
Model Answer:
It has been widely noted that, with the growing use of computers and calculators both in the classroom and in the home, the level of literacy and mathematical ability of students is dropping. This raises serious doubts about the value of the progress of science and technology. Here I will discuss the pros and cons of this question.
First of all, advances in science and technology have certainly brought about many benefits for mankind. They have made our lives more comfortable and healthier. In addition, they have eased the burden of work for most people and provided them with more leisure opportunities, while at the same time increasing productivity dramatically.
Nevertheless, it cannot be denied that technology has some negative side-effects. As mentioned above, with computers which check spelling, grammar and calculation for them, students have little incentive to learn how to do these things for themselves. Also, the availability of TV programs and videos encourages an unhealthy, sedentary lifestyle.
Another aspect of this issue is that technology may be good or bad, depending on how we use it. For instance, dynamite may be used to make road construction easier, or it may be used to kill people. Again, nuclear reactors can supply huge amounts of cheap electricity, but if they are carelessly handled they can cause devastating pollution.
We can conclude that the progress of science and technology has both positive and negative effects. What we must do is to make sure that the positive ones are encouraged and the negative ones are eliminated as far as possible. Among other things, this means that students are warned not to let computers and calculators do all their work for them.
