'Telecommuting' refers to workers doing their jobs from home for part of each week and communicating with their office using computer technology.
Telecommuting is growing in many countries and is expected to be common for most office workers in the coming decades.
How do you think society will be affected by the growth of telecommuting?
Model Answer:
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.
科技類雅思作文【2】
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.
