阅读下列短文，从每题所给的四个选项（A、B、C、D）中选出最佳选项。

Mr. Lewis was a dance teacher. He was a nice man and always had a lot of students. One year he moved to a new town, and was soon teaching many students in the dance school there, but he decided to move again to a big city. He would have more work there.

When one of his students heard that he was going to leave, she said to him, "The new teacher won't be as good as you are." Mr. Lewis was happy when he heard this, but he said, "Oh no. I'm sure he'll be as good as I am ---- or even better." The student said, "No. Five teachers have come and gone while I've been here, and each new one was worse than the last."
