Using the computer

I think computer is very useful. I often use the Internet and Microsoft Word. We can gather a lot of information by Internet. Microsoft Word is used when I write some reports. We also have to use computer when we do our some home works. I have my own computer in my house, and I use it everyday. It can help me when I have to do my homework. But it is not good that we use it too much because it tasks our eyesight. I am always tired after using computer so long time.
