（一）my hobby
There are a great many hobbies to choose from.Some people enjoy collecting coins or stamps,others choose to spend their time on sports or music.I have many hobbies,but playing basketball is my favorite one.At weekends,we always build a team to play basketball against another one in our neighbourhood.The competitions brought us so much fun.I think playing basketball is a good way to build up one's body and relax oneself.But I will always remember that it's unwise to spend too much time playing
（二）Dogs
Nowadays many people like to have dogs as their pets.Dogs are friends of man not only because they are lovely but also because they are faithful to their masters.
Dogs can do a lot of work for man.They play with us.They hunt with us.They keep door for us.But long ago,dogs all over the world were wild.
Dogs can date back to the Stone Age.All dogs have the same ancestor.It is believed that their ancestor was much like a wolf.Other animals,such as the fox,came from this ancestor,too.Hundreds of thousands of years ago,man began to tame wild dogs.After the dogs were tamed,they were trained.The strong dogs became working animals.They were trained to pull heavy loads.They learned to keep an eye on the sheep and other animals.Working dogs had other jobs,too.
Some dogs were not strong.But they could help man hunt for game.Other dogs were best as pets.
Today,there are more than 100 kinds of dogs in the world.
（三）Learning to Play the Piano
When I was a child,I was fascinated by the melody of piano on the screen.At that time,I dreamed of being a pianist and having my own piano.
At the age of five,my father bought me a beautiful piano as my birthday present with the money they had saved for a long time.At the same time,my father found a piano teacher for me and every day I would practise it again and again as my father demanded.Before long,my interest in piano was transferred to other things.I began to escape the practice as much as I could.My father found out my impatience.He encouraged me and was stricter with me than ever before.With his help,
I underwent the hardest time and devoted myself to the piano.
Now,in my spare time after a long time of study and hard work,I always play the piano and enjoy the beautiful music.
（四）Music
There are two important kinds of music in the world --one is written down and the other is not.Many people earn their living by writing music.They write songs for popstars and music for films and TV plays.They usually write exact instructions how the music is to be played.
Folk music has been passed down from one goneration to another.At first it was never written down.Pe ple learnt the songs from their families,relatives,neighbours and friends in the same village.These songs were about country life,the seasons,animals and plants,and about love and sadness in people's lives.
Early performers of music were popular and respected.They used to learn hundreds of songs by heart.On festivals they used to act and sing in praise of heroes who lived long ago.This was at a time when there was no radio,TV or cinema.Many of the country people could neither read nor write.In this way stories were passed on from one person to another.This continues in some countries even today.
In some parts of the world nowadays,you often see musicians performing in the streets to passers-by.They put a cap on the ground in front of them,so that people who like the music can drop coins into it.
