     To me, music is food and water.I can't live without it.I know this is not true for everybody.Many

people don't listen to music and they can get along quite well.But music is everywhere in our life.For

example, when you watch films or TV plays,do you find them interesting if there is no music?You

would find them boring.And when you are waiting for the train or the plane,you would like music

because it makes the time seem shorter.

     It is true that music is everywhere in our life.Some people like to sit by the sea and listen to the

sound of the sea.Some enjoy listening to the singing of birds.Those sounds are some kinds of music.
