25. Discussion
What are the advantages and disadvantages of computers?

26. With the development of IT technology, more and more families have computers in their homes. Whether this is good or bad, people's opinions t are different.
    People who are for it say that with computers in home we can easily find more useful information and we can make more friends because of QQ and MSN and so on. However, People against it insist that children may spend more time in playing computer games. There is no doubt that this will do great harm to their study.
    To my mind, I think if we use computers in reasonable ways, it will bring us more advantages than disadvantages.

27. With the development of IT technology, more and more families have computers in their homes. Whether this is good or bad, people's opinions are different.
Those who welcome the Internet hold that it brings us great convenience and efficiency. Firstly, we can send s to our friends in other countries in a few minutes while sending a traditional letter takes us at least a week and costs much. Secondly, we can make friends with people from all parts of the world. It overcomes the geographical barriers and makes the world smaller. While people speak highly of the Internet, its drawbacks should not be neglected. For one thing, it leads to psychological problems. An Internet-addicted person tends to be isolated, self-centered and unsociable. For another, there is a sharp rise in the number of cyber crime. More and more financial crimes are committed via the Internet.  In my opinion, I think if we use computers in reasonable ways, it will bring us more advantages than disadvantages.
