Beethoven had an ugly face , and he had a very bad temper (脾气), but people like to ask him to their homes. When he lost his temper, they forgave (原谅) him. He was often poor and ill during his life. After one illness, he suddenly found himself deaf. At that time he was just 31. What a blow(打击) it was on him! But this didn't stop Beethoven from walking on in his life. He went on writing much music. He wrote long pieces and short pieces, happy ones and sad ones all his life. During his life, he composed (作曲) about 300 pieces. To people's surprise, he wrote some of his best and most beautiful pieces after he became deaf. Many of them are known and loved all over the world.
