晚上，当小主人在灯下看书的时候，卫生间传来一阵吵闹声，原来是牙膏大哥和牙刷小弟在争论谁更有价值。“第三次世界大战”就要开始了。牙刷小弟双手叉着腰说：“如果没有我，你就不能帮小主人刷好牙！如果不是我，你肯定要被扔进垃圾桶里！”牙膏大歌听了牙刷小弟的话，气得火冒三丈，瞪着眼睛说：“才不对呢！如果没有我，你就算能帮小主人刷牙，也不能把牙齿里的蛀虫消灭掉。”
In the evening, when the little master was reading under the light, there was a loud noise in the bathroom. It turned out that the big brother of toothpaste and the little brother of toothbrush were arguing about who was more valuable. The third world war is about to begin. "Toothbrush little brother hands crossed waist said:" if not for me, you can not help the little master brush teeth! If it wasn't for me, you'd be in the trash! " The toothpaste song listened to the words of the toothbrush younger brother. He was so angry that he stared and said, "it's not right! If you don't have me, even if you can help the little master brush his teeth, you can't eliminate the moths in his teeth. "
就在它们争论得不可开交的时候，小主人来到卫生间，打算要刷牙，卫生间里立刻安静下来。只见小主人把牙膏挤在牙刷上，把清水装在杯子叔叔的胸怀里，就开始刷牙了，边刷还边哼起了《刷牙歌》……
Just as they were arguing, the little master came to the bathroom and planned to brush his teeth. The bathroom was quiet immediately. I saw the little master squeeze the toothpaste on the toothbrush, put the clear water in the cup uncle's chest, and began to brush his teeth, while brushing and humming the "brushing song"
小主人刷好牙去睡觉了。杯子叔叔就对牙膏大哥、牙刷小弟说：“你们不要吵了！看到了吧！小主人刷牙的时候，缺少谁都不行，只有大家团结合作，才能帮小主人把蛀牙刷成一副洁白的牙齿，你们说是不是呢？”听了杯子叔叔的话，牙膏大哥和牙刷小弟都红了脸，惭愧地低下了头，说：“杯子叔叔，你说得对，我们以后再也不吵架了！”
The little master brushed his teeth and went to bed. Uncle cup said to big brother toothpaste and little brother toothbrush, "don't quarrel! See! When I brush my teeth, I can't do without anyone. Only when we work together, can we help my little master brush the decayed teeth into a pair of white teeth, don't you think? " After listening to Uncle cup's words, brother toothpaste and brother toothbrush blushed, lowered their heads in shame, and said, "Uncle cup, you are right, we will never quarrel again!"
房子里的灯熄灭了，它们的小主人睡着了，杯子叔叔它们也睡觉了。整个屋子都安静下来，只有天上的星星宝宝和月亮妈妈在微笑着……
The lights in the house went out, their little owner fell asleep, and their uncle cup fell asleep. The whole house is quiet, only the stars in the sky and the mother moon are smiling
