One possible version：
Attention, please! I’m going to give you a summary of today’s discussion about whether we would go on-line in our spare time.
Many students think we can go on-line as much as possible in our spare time because we are free then. Through the Internet, we can gain plenty of the newest knowledge and the latest information at home and abroad. What’s more, network offers us a convenient way to communicate with each other. The Internet makes our lives outside class colorful and various.
On the other hand, a few students partly agree to this idea. Going on-line is part of our daily life. But they suggest a time limit. They’ve found that more students are playing computer games or chatting instead of studying their lessons or looking up materials. There are a few students who are often absent from school in order to go on-line for fun.
Thank you.
