     The American book " Who Moved My Cheese" has been a best- seller all over the world.   1   .

Now its author Spence Johnson has written a book just for teenagers.

     The book tells us that when facing changes in our lives, like a new school or new friends, don't be

afraid. Instead, use these changes to make a better life.

       2    A school is changing from having two terms to three terms because there are too many

students.

     Several teenagers are talking about this. Most of them are unhappy and worried. But Chris laughs

and tells a story about two mice, two little people and some cheese.  3     Here, cheese means

something important in life, like moving to a new class or getting into college.   4     The mice realize

that they can't change what has happened and have to find more cheese.   5   The little people, however,

can't do this. They are afraid of change so they find no cheese.

     After Chris finishes the story, the friends understand one thing: to get more cheese, move in a new

direction quickly . His friends understand how this can be used in the changes all teenagers face, such

as doing well at school or having good relationships or just feeling good about yourself.
