Teeth and Lips are good friends．They help eath

other all the time．We can enjoy delicious food with

their help.

One day the Teeth say to the Lips，“We're more importantthanyou． Wecaneatsoftfoodandhard 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 drty．

Now the teeth know they are wrong. The Lips are very important，too．

唇亡齿寒

牙齿和嘴唇是好朋友，它们一直互相帮助。在它们的帮助下，人们能够享用美味的食物。

一天，牙齿对嘴唇说：“我们比你们重要得多。我们不仅可以吃软的食物，还可以吃硬的食物。你们什么也不会做。”

嘴唇一句话也没说，但他们离开了牙齿。然后，牙齿整日露在外面。他们又冷又脏。

现在牙齿知道它们错了，原来嘴唇也是很重要的。
