13. One day, in the English class, the students were learning the words about the parts of the body. Suddenly, Tom put up his hand and said to his teacher, "Mrs. Brown. I lost my baby tooth."
"Great," Mrs. Brown said. Then she asked the class if anyone had any advice for Tom.
Naoko, a Japanese girl, put up her hand first. "If it is a lower tooth, you should throw it over the roof of your house. If it is an upper tooth, you should put it under the floor. Then your new adult tooth will grow well."
"You shouldn't throw your baby tooth away, Tom. You should keep it and give it to your mother," said Jack, a French boy. "She will make it into a necklace (项链) for you to wear."
Gorge, who was from America, had some different advice. "You should take your tooth home and put it under your pillow (枕头) when you go to sleep. The tooth fairy (牙仙) will come to keep your tooth and give you good luck. Sometimes she even brings a small toy." "You should put your baby tooth under your pillow when you go to sleep, Tom. The little mouse may change it into a coin and bring you good luck," Harry, a Spanish boy said.
Tom liked Gorge's advice the best. Mrs. Brown said to him, "Whatever you decide, you should show your mother your tooth when you get home."
After getting home, Tom showed his mother his tooth and told her his plan. The next morning, Tom woke up and looked under his pillow. The tooth was gone. In its place, he found a dollar and a letter. This is what the letter said:
Dear Tom,
Great! You lost your first tooth. I will keep it forever. You should buy something nice for yourself with this money.
Love,
The Tooth Fairy
