technology is a necessary force in modern life. we use technology to develop economy, change our life and quicken the pace of development. without it, we might still stay in a poor society. we might have no tvs, no computers and even no lights. we might have to work by hands instead of by machines and read many books to gain new knowledge instead of making use of computer nets. it's believed that technology improves our life.
but technology is not always a positive force in modern life. if it is not used in the right way, it may be harmful and even dangerous to people. for example, as a result of advanced technology, computer viruses have been made by some people with personal purposes, and obviously everyone knows what harm they do. we can see that under the influence of the negative effect of technology, our society may be faced with a great danger.
so we should make use of the positive force of technology to develop our modern life and reduce its negative effects.
