Shirley was a shy girl and she seldom answered questions in our class. She was afraid of making mistakes(犯错误). Sometimes she couldn' t finish her homework because she didn't want to make any mistakes. ①Nothing changed until Mr Smith，a new teacher, cametoour class.

One morning, Mr Smith asked Shirley to answer some questions. After a while, she was in tears because she gave the wrong answers. At that time, Mr Smith took out a small box.②盒子里装满了橡皮。" Look, Shirley," he said, standing next to her. "I have something to show you. "He took out the erasers and put them on the desk. "Look at these erasers, Shirley, he continued. "Do you know why they are become smaller and smaller. That's what you must learn---everybody makes mistakes, but they can be valuable experience and teach you something important.” Then he left one eraser on Shirley's desk.

From then on, Shirley changed a lot. Instead of being shy, now she is active and confident. She isn’t afraid of making mistakes any longer
