Computer have improved our lives while others think computers have caused problems 计算机改变了大家的生活，而有些人则觉得计算机导致了问题。
In my opinion I think computer does have more positive effects towards our lives than its negative sides. First, we can keep in touch more closely with the help of computer. For example, by using Emails or MSN, I can leave messages to my friends in the United States no matter when. But before computer was invented, one have to wait nearly several months to get a letter from friends abroad. Second, with computer, we can get information from all over the world easier and more convenient. I just want to keep myself informed of whats going on in the world. They can equip me with knowledge and information.
