2017下半年雅思考試科技作文范文一
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.

The spread of telecommuting is sure to have far-reaching effects on society. By itself, telecommuting refers to offiice workers spending much of their time working from home and using electronic technologies to communicate with their employers. The broader implications of telecommuting, however, may involve changes to corporate structure, workers' lifestyles and even urban planning.
The most obvious changes may be apparent in the `normal' offices of companies, governments and other organisations. If even half the working week is spent telecommuting from home, then we would initially expect many empty desks in the offiice. As offices grow smaller, workers coming in for the day would be expected to share desks with their absent colleagues. This, in turn, may affect the social atmosphere of an organisation, however, as less social contact with one's colleagues could harm morale and loyalty.
For the individual office worker, telecommuting would mean spending more time at home. For a parent with young children, this may be a blessing. Moreover, many telecommuters would be able to work the hours they wished: having a nap in the afternrnoon, for example, but working some hours in the evening. One substantial benefit for all telecommuting workers is that there will be no need to travel to work, allowing more free time.
The structure of urban life is also likely to be affected by telecommuting. We would expect to see fewer cars on the road during peak hours and, eventually, a smaller concentration of offiices in cities' central business districts. In short, people will have less reason to travel to city centres from outlying areas. As more people work and live in the same location, shops and cultural events will likely relocate themselves out of the city centre.
In sum, telecommuting will serve not only to change the way we work but also the way we live.

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.
