Alice always wanted to be a singer. Music was the most important thing in her life and, to tell you the truth, she took lessons for years, and practised every day, but in spite of all this, her voice didn’t improve. Honestly, it didn’t get better, it just got louder.
Her teacher finally gave up and stopped the lessons, but Alice refused（拒绝）to give in, and one day she decided to give a concert and invited her teacher to attend.
The teacher was very worried about what to say after the concert. She knew it would be terrible and it was. She didn’t want to tell a lie, but she didn’t want to hurt Alice’s feelings, either. Finally, she got an idea and went backstage (后台) to greet her pupil.
“Well,” said Alice, “what did you think of my singing?”
“My dear,” said the teacher, “you’ll never be better than you were tonight.”
