Mozart was one of the most famous musicians in the world. One day, he was walking along the street when he saw an old man (play) the violin. The old man's shoes were worn out and they needed (change). Besides, the hat in front of him was still empty. Mozart was a kind-hearted man so he decided (help) the poor old man. He asked the old man whether he enjoyed Mozart's works. The old man nodded but said sadly, "I want (meet) Mozart in person and learn from him, but I didn't know him at all." Hearing that, Mozart couldn't help (smile).
Mozart took the violin from the old man and started (perform). His wonderful performance attracted many passers-by. Soon the old man's hat was full of money, and he was thankful.
