I am sure that everybody in his／her life has used computers．Nowadays you can feel their presence everywhere—at home，at school，at work and they certainly make life easier．On the other hand，there are people who can work without them．

Anyway, I believe their presence is a good thing．Life with them seems less difficult and more comfortable．You can use them to choose your meal，to withdraw your money，and also to save your time，because these operations ale all controlled by computers．Therefore，you can hardly imagine the modern world without them；the whole planet seems to be one big computer society．

Nevertheless，problems call often appear in this area，too．To have a computer means you have to be quite rich and have the necessary skills to use it．However, think about questions like，“Are computers available for everyone, for rich and poor people，for people from villages and people from cities? Aren’t they too expensive? Is everyone able to learn how to use them and does everyone have the chance to access and work with them? How could everything in the future be dependent on them?”Therefore，I think our society will be divided into two pans．One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out of society and will actually be left far behind the other group．

Another question that bothers me is，computers are important and they’re good things in our life, but they aren’t everything. They are good as a help at school, quite often as entertainment, especially for young people, as an necessary tool to help in research etc. , but I think we shouldn’t be so dependent on them, because computers are only machines and machines can’t feel anything, can’t be human and sympathetic, and every action performed by computer can be interfered(干涉) with could cause these machines to crash or work badly.

In conclusion, I would like to say I am not against computers. I use computers too, but people should be wary all the time.
