Books are our good friends. When we began elementary school, we sta rted our friendship withthem. T hey never leave us unless we throw them away. When we are alone, they help us to getrid of lonely feelings. When we ar e in low spirits, they encour age us to stand up again. Whenever we are in trouble, they always offer help to us.

　　However, not all books are worth reading. Certain ones can be harmful to our young people whohave committed crimes which have resulted in their being sent to prison. This is the result ofthe negative influence that these books which are not worth reading have upon their youngreaders .

　　So it is important to make wise use of books . Our aim is not only to read them, but also to usethem. How can we use them mor e wisely? The answer is to practise what we have read. Onlyby pr actising and using the knowledge we have acquired from books, can we achieve more inour life .
