When I was teaching a Grade One class, Billy's tooth just popped out. He was examming it in wonderment when Joan turned around to tell him about the tooth fairy: how she put her tooth under her pillow when she went to bed, and when she woke in the morning, the tooth was gone, a shiny quarter in its place. Billy put his tooth in his pocket thoughtfully. When it was time to go home, Billy walked over to Joan, handed her the tooth and said:"you can put my tooth under your pillow and bring the money on Monday."

我那时正在教一年级的一个班。比利的一颗牙齿掉下来了。他正好奇地研究它，这时，琼转过来告诉他牙齿精灵的故事:她上床睡觉的时候把牙齿放在枕头底下，早上起来的时候，牙齿不见了，却放着一枚光闪闪的2角5分硬币。比利小心地把牙齿放在口袋里。到了该回家的时候，比利走到琼身边，把牙齿交给她说道，“你可以把我的牙齿放在枕头底下，星期一的时候把钱带给我就行了.”

Tooth fairy: 牙齿精灵,是西方文化中儿童喜欢的人物。儿童把掉下的乳牙送给精灵，会得到小额金钱或者小礼物。
