介绍:
10 Teeth and lips are good friends.They help each other all the time.We can enjoy delicious food with their help. One day the Teeth say to the Lips,"We're more important than you. We can eat soft food and hard food.You can't do anything." The Lips don't say a word,but they leave the Teeth.Then,the teeth are out all day.They are cold and dirty.Now the teeth know they are wrong.The Lips are very important ,too.
