    Beethoven, a famous musician in the world, was born in Germany in 1770. In his childhood Beethoven

didn't have a happy life. His father was a singer. When he was only four, his father began to make him

practise hour after hour on different musical instruments. If he did not put his heart into it, his father would

beat him or make it hard on him.

    Beethoven loved music and he learned so fast that he was able to go around to give concerts, when he

was only a boy of eleven. At the age of seventeen, he won high praise from Mozart, the great musician at

that time.

    Beethoven was often poor and ill during his life. After one illness, he suddenly found himself deaf (聋).

At that time he was only thirty-one. It was a blow (打击) to him indeed.

    But he still went on working and writing music pieces. To people's surprise, some of his best pieces

were written after he lost his hearing.

    In 1827, leaving more than 300 pieces, the great musician died. But his name is still remembered to this

day.
