When I was young, I didn't like to clean my teeth. I often find many excuses(借口)to go to bed wbrushing my teeth.
One day, I read a story about the tooth fairy(牙仙). It is said that if a child puts a fallen(落下来的)tooth under the pillow(枕头), the tooth fairy will take it away and lmoney when the child falls asleep at night. I asked my mum, "Is there really a tooth fairy, Mum?" "Maybe there is, "my mum smiled and answered. "But your teeth are terrible. The tooth fairy won't like them. "
A few days later, one of my teeth fell out. Just like my mother said, it was very terrible. It was yellow with a black hin it. I rushed into the bathroom to brush it and use a toothpick to pick it carefully. After that, I put it under my pillow.
The next day, I woke up early and checked my pillow g. The terrible tooth was m！One yuan with a piece of paper was under my pillow！It said:" You should protect your teeth more carefully. If you give me a terrible tooth like that a, I won't like it. "
Days passed fast. I knew that the tooth fairy was my mum, though no one told me the truth.
