     Two students started quarreling at school. One student shouted dirty words at the other, and

a fight (打架) began.

     What can be done to stop fights like this at school? In some schools, the disputants (争执者)

sit down with peer mediators.

     Peer mediators are students with special training (训练) in this kind of problems. Peer mediators

help the disputants to talk in a friendly way. Here are some of the ways they use:

1. Put what you think clearly but don't say any-thing to hurt the other. Begin with"I feel…" instead

of"You always…"

2. Listen carefully to what the other person is saying. Don't stop the other person's words.

3. Keep looking at the other person's eyes when he or she talks.

4. Try to see the other person's side of the prob-lem.

5. Never put anyone down. Saying things like "You are foolish (愚蠢)" makes the talk difficult.

6. Try to find a result that makes both people happy.

     Peer mediators never decide the result or the win-ner. They don't decide who is right and who

is wrong. Instead, they help the two students to find their own"win-win" result. A"win-win" result

can make every-one feel good.

     Peer mediators' work is often successful just be-cause it gets people to talk to each other. And

getting people to talk to each other is the first step in finding a "win-win" result.
