8.阅读表达。

To me, music is food and water. I can't live without it. I know this is not true for everybody. Usually lots of people go to concerts or listen to music records. Maybe some of you don't do these and you get along quite well, but music is everywhere in our life. For example, when you see movies or watch TV plays, will you find them interesting if there is no music? I'm sure you will find them boring. And when you are waiting for the train or the plane, you would like some music because it makes the time seem shorter.

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 kind of music. So music has a meaning for everyone to some extent. （程度） Of course, it has special meaning for people like me. We spend our lives playing or writing music.

Someone said," Through music a child goes into a world of beauty, learn to take care of others and makes his mind and body healthy." Music is really an important part of our life.
