Bill was a boy of 15 in Grade 9. His parents went gambling(赌博) day and night. Nobody cared about him. He always failed in his exams. So his teachers didn’t like him, nor did his classmates play with him. Bill often slept in class because his heart was not in school. He almost gave himself up.

One day, Miss Jones, a new teacher, came to Bill’s class. She was a smiling, beautiful woman. Bill was in love! For the first time in his young life, he couldn’t take his eyes off his teacher; yet, still he failed.

It was Miss Jones’ class. She was asking a question. “I’d like the smartest boy to answer my question.” Then she said loudly, “Bill, please!” Bill was surprised. And he stood up without a word. “Just try it! I believe you can!” After school, Miss Jones had a long talk with Bill. She told him that she cared about him and believed in him.

Bill thought a lot that evening. From then on he arrived at school on time every day. Miss Jones helped him with his homework in the afternoon. She even cooked delicious food for him. She told Bill, “Nothing is impossible if you put your heart in it.” Later, Miss Jones gave another exam. Bill did it with all his heart. He was very excited to find that he had passed the exam. Now Bill discovered that he also could learn well. A change took place in Bill’s heart.

You see, one teacher saved one boy, it’s simple, really.
