     Just as in face-to-face communication, there are some basic rules of behavior (行为)

that should be followed on the Internet. The basic rule is simple: treat others in the same

way you would want to be treated. ①Imagine how' you'd feel if you were in the other

person's shoes.

      For anything you're about to send: ask yourself, ''Would I say that to the person's

face?" If the answer is no, rewrite and reread. If someone in the chat room is rude

to you, you needn't fire back. You should either ignore（不理睬）the person, or use your

chat software to block their messages. Remember to respect the beliefs and opinions of others

in the chat room.

     ②Offer advice when asked by newcomers, as they may not be sure what to do or how

to communicate. When someone makes a mistake, be kind about it. If you do decide to tell

someone about the mistake, point it out politely. At the same time, if you find you are wrong,

be sure to correct yourself and apologize to those that you have offended (冒犯). ③询问

别人诸如年龄、性别和家庭情况等隐私问题是不礼貌的。 Unless you know the person

very well, and you are both comfortable with sharing personal information, or don't ask such

questions.
