Robby was 11 years old when his mother (a single mom) sent him to have his first piano lesson. I prefer that students begin at an earlier age, but Robby said that it had always been his mother’s   1  to hear him play the piano. So I   2  him as a student.
Although Robby worked very hard, he didn’t have a basic   3  of music. However, he never   4  up and continued. And at the end of each weekly lesson he’d always say: “My mom is going to hear me   5  some day.” But it seemed   6 . He didn’t have a natural talent or ability for music.
One day Robby   7  to our lessons very late. He told me that his mom had been 8  and unable to take him to piano lessons, but he was still   9  in class. He asked if he could take part in my concert and I   10 .
The night of the concert came. The high school gym(体育馆) was   11  with parents, friends and relatives. The concert was going well. Then, Robby came up on stage. He announced (宣布) that he had chosen Mozart’s Concerto No 21 in C Major. I was not prepared for what I heard next.   
His   12  danced on the keys…
He played so   13  that everyone was on his feet, clapping excitedly. In tears, I ran up on stage, “Oh, Robby! How could you do it?”
“Well, Miss Hondorf... remember I told you my mom was sick? Well, actually she had cancer(癌) and   14  away this morning. And well… she was born deaf, so tonight was the first time she ever heard me play at the   15 . I wanted to make it special and show her I could do it! My mother’s dream came true at last.”
