There was a story many years ago of a school teacher--- Mrs. Thompson. She told the children on the first day that she loved them all the same. But that was a lie. There in the front row was a little boy named Teddy Stoddard. He didn’t play well with the other children and he always needed a bath. She did not like him.

Then Mrs. Thompson got to know that Teddy was actually a very good boy before the death of his mother. Mrs. Thompson was ashamed(惭愧的) of herself. She felt even worse , like all her other students, Teddy brought her a Christmas present too. It was his mother’s perfume(香水)。

Teddy said, “Mrs. Thompson, today you smell just like my Mom used to.” After the children left she cried for at least an hour. On that day, she stopped teaching reading, writing and math. Instead, she began to teach children.

Mrs. Thompson paid particular attention to Teddy. The boy’s mind seemed to come alive. The more she encourage him, the faster he improved. By the end of the sixth grade, Teddy had become one of the smartest children in the class.

Six years went by before she got a note from Teddy. He wrote that he had finished high school, third in his class, and she was still the best teacher he ever had in his whole life. He went to college. Mrs. Thompson got two more letters from him with the last one signed, Theodore F. Stoddard, M. D.(医学博士).

The story doesn’t end there. On his wedding（婚礼） day, Dr. Stoddard whispered（低声的说） in Mrs. Thompson’s ear, “Thank you, Mrs. Thompson, for believing in me. You made me feel important and showed me that I could make a difference.”

Mrs. Thompson, with tears in her eyes, whispered back, “Teddy, you have it all wrong. You were the one who taught me that I could make a difference. I didn’t know how to teach until I met you.”
