     Have you ever had problems in your life and don't know how to be happy? If so, you will find Being a Happy Teenager written by an Australian writer Andrew Matthews.

In his book, Matthews tells us how to have a happy life and answers the questions of teenagers.

     There are many subjects, such as parents and friends, and the book says we should stop being angry

and should forgive(宽恕). The book tells us some useful skills, such as how to put what you have learned

into pictures of your mind to, make your memory better. Many teenagers think that happiness comes from a good exam result or 'praise(费扬) from other people. But you can still be happy when there are no such "good" things.

     Success comes from a good attitude(态度). If you learn from problems, you will have success in the

future. Some school students have problems, such as being too tall or too short. But Matthews tells us that happiness comes from thinking in a positive(积极的) way. If you are tall, people notice you and you can

get a better view(视线) at the movie; if. you are short, your clothes and shoes take less room in your

bedroom! This is Matthews' most important lesson: 6*You choose to be happy! "
