    James is a good student and he has lots of friends，but he also has a problem. Some older boys are bullying(欺负)him at school. James is very unhappy and he doesn't know what to do about it. Here are some suggestions to him and other teenagers in this situation.
    Don't feel worried. It's not your fault(过错)! Being bullied can make you feel very lonely and angry，but you are not alone. Don't feel that you have to hide the problem. You should find a person you can trust，and tell them. It might be your teacher，your parents，or even your friend's parents. After you tell someone，you will get some support and feel some relief(解脱).
    Speaking to an adult might make you nervous，but here are other things you can do. Some people express their feelings more easily on paper. Write a letter to someone or keep a diary. Include all the details(细节)about what the bullies do, as well as when and where the bullying happens. You can use it as proof to show what is going on. And it is a wonderful idea to show your letter or diary to a teacher or another responsible adult. Then the bullies will feel very afraid if their names appear in a letter!
    Also，don't show you are sad and don't try and fight with the bullies. You could get in trouble yourself. Ignore them and just walk away. The bullies will soon stop.
