求一篇英语演讲稿，关于如何使用电脑，电脑用途之类的 急！！！！

It is good for us to learn how to use computers. And we can learn about more knowledge by computers.Playing computer games make us cleverer. But some of us spend too much time in computer games,Some of us make friengs online.They are awaysat the bottom of the class . I think you shouldn't get on line when you are studing at the school.you'd better get on line in Winter holiday or Summer holiday. But you can't lose yourselfs in Internet.I wish you to be heathier and happier.
