To me, life without music would not be exciting. I realize that this is not true for everybody. Many people get along quite well without going to the concert, and listening to the record. But music plays an important part in everyone’s life, whether he realizes it or not. Try to imagine, for example, what films or TV plays would be like without music. Would the feelings, the moving plot（情节） and the greatest interests be so exciting or dramatic? I’m not sure about it.
Now, we have been speaking of music in its more common meaning—the kind of music we hear in the concert hall. But if we look at some parts of music more carefully, we discover them in our everyday life too—in the rhythm(节拍) of the sea, the melody of a bird in the woods and so on. So music surely has meaning for everyone, in some way or other. And, of course, it has special meaning for those who have spent all their lives working on playing or writing music.
It is well said, “Through music a child enters into a world of beauty, express himself from his heart, feel the joy of doing things alone, learns to take care of others, develops his mind and makes his body strong.”

The Peppered Moth, a kind of insect(昆虫), is found in England. It is light brown in colour and likes to settle(栖息) on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.
But with the development of industry(工业) , smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change colour. It became darker as well. Though the change took several years, some scientists soon notice that newly-born moths were a little darker than usual.
A scientist with the name Kettlewell decided to make a careful study of this phenomenon(现象). He marked some of the light moths and some of the darker ones, and set them free in the woods near Bermingham, an industrial city. Later, he recaptured(重新捕获) as many as the marked moths as possible. The results were as follows.
| | light moths | darker moths |
| Moths set free | 201 | 601 |
| moths recaptured | 34(16%) | 206(34%) |
Can you imagine what would happen to the Peppered Moth as the air became cleaner again?
