8．
In class，Peter put up his hand and said to his teacher，"I lost my baby tooth．"
"Congratulations，"Mrs．Gilbert said．Then she asked the class if anyone had any advice for Peter．
Keiko，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 properly．"
"You shouldn't throw your baby tooth away，Peter．You should keep it and give it to your mother，"said Jack，a French boy．
"Why should I do that？"asked Peter．
"She will make it into a necklace（項鏈） for you to wear，"said Jack．
Jorge，who was from Mexico，had some different advice．"You should take your tooth home and put it under your pillow（枕頭） when you go to sleep，"Jorge said．
"Why should I do that？"asked Peter．
"Because the tooth fairy（牙仙） will come to keep your tooth and give you good luck．Sometimes she even brings a small toy．"
Peter liked Jorge's advice the best．Mrs．Gilbert said to him，"Whatever you decide，you should show your mother your tooth when you et home．"
When Peter got home，he showed his mother his tooth and told her his plan．The next morning，Peter 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 Peter，
Congratulations!You lost your first tooth．I will keep it forever．You should buy something nice for yourself with this money．
Love，
The Tooth Fairy
