Computer is a nice thing for us， so many students spend much time on it。 Computer is very interesting ， so we often want to play it。 We always play computer using the timeof the study， so many students" schoolwork becomes bad。
Playing computer isn’t a bad thing， but playing too much time is bad。 Playing computer games is bad for eyes， so we should’t play too much time。 I think it is very good for us to spend three hours on it every week。
I think students must know what is computer used for ， and how to use it。 Playing it in the best way。Spending a little time on computer is very good for us。
