Books are our good friends. When we began elementary school, we started our friendShip with them. They never leave us unless we throw them away. When we are alone, they help us to get rid of lonely feelings. When we are in Iow spirits,they encourage us to stand up again. Whenever we are introuble, they always offer help to us. However, not all books are wortli, reading. Certain ones can be harmful to our young people who have committed crimes which have resulted in their being Seat to prison. This is the result of the negative influence that these books which are not worth reading have upon their young readers. So it is important to make wise use of books. Our aim is not only to read them, but also to use them. How can we use them more wisely? The answer is to practise what we have read. Only by practising and using the knowledge we have acquired from books,can we achieve more in our life.
