In the last few years the Internet has become a widespread phenomenon(现象) around the world. People have started to use the computers just like they used to watch TV. Whenever we get hungry, we simply order a pizza through the Internet and while we are waiting for the food, we can send an important business e-mail concerning some sales for tomorrow. It is, in fact, very comfortable to just simply sit down and have a chat with somebody from South Africa about fishing and get some important advice. Sometimes when you are sad and are feeling lonely, if you go on the Internet, you can find good entertainment that will keep you busy.
To make a long story short, we just don’t have the time to communicate with people in person anymore. Besides, there is so much information easy to get on the Internet that when we start surfing, we find it hard for us to get away from the computer. There are a lot of people who are addicted(沉溺于) to TV and watch it 5 to 7 hours a day, while recently addiction to the Internet has become a very serious problem. You might think that these kinds of things could never happen to you, but it is not really true. To prevent yourself from getting addicted, the most important thing is to make sure that you are not spending too much time in front of the screen. Although it might seem to be easy to pull yourself away from the Web, it is simply not the case. You might have to make an effort to place some limits(限制) on yourself.
