Today,in our English class,we discussed whether it is necessary for middle school students to Р                       chat on line. Some agree while others don't. Those who think It's good to chat on line think they Р                       can relax themselves. Also they can keep in touch with their friends and make lots of friends. Р                       However,some of the students think chatting on line is too boring and It's a waste of time. What's Р                       more,some students even put the answer to the homework on line. It's bad for our study. Р                            In my opinion,every coin has two sides. It's convenient for us to do that. We can chat on line Р                       sometimes,but we can't spend too much time doing that.
