Different people have different hobbies. For example, some people like reading, some people like swimming and some people like collecting something and so on. I have many hobbies, such as reading, skating, and traveling. I used to read books in my free time. I like reading because I could learn much by reading. At that time, reading was part of my life. Every day, I spent most of my free time reading books, newspapers and magazines. At night, I could hardly get  to sleep without a novel in my hand.

But later I found I could only learn from books by reading. I couldn’t get knowledge from others. I needed a  change . Traveling is my hobby now. I can visit many different places by traveling. I can learn a lot about people, geography and history. It’s very interesting.

I have many good friends. They all have their hobbies. Ann studies very hard. So her hobby is reading all kinds of books. Tony loves working with her hands, and his hobby is gardening. He usually plants flowers and trees in his yard. Judy is a quiet girl. She likes knitting(编织). She always knits sweaters for her dolls. We have different hobbies, but we are all good friends.
