Each of us should unite. Unity is success. Only unity can lead to a happy life today, so unity is strength. If everyone is not United and only cares about themselves, nothing can be done. Every one of us can unite as one and do things wholeheartedly, even if it is a big difficulty, it can be overcome. As long as we unite to do it. No matter how hard it is. I'm sure I can do it well.

The members of the oral family are lips, teeth, tongue and saliva. They are United as a happy family. Have you noticed? They have been quietly serving us.

Lips are red, which adds luster to our faces and makes our faces red; Teeth, although inside, will grind food and send it to our stomachs; Where's the tongue? It usually doesn't appear, but it will turn the food over and help the teeth; ; The saliva that also serves the people silently can make the lips moist.

If you have a toothache, they will let the doctor see you. If the doctor wants to pull out a tooth, the tooth is very sad. They don't hurt, they just want to lose a brother. Others are equally depressed! If, when eating, your teeth bite food, you think too fast and accidentally bite your tongue. Teeth will apologize. Say sorry. Although the tongue hurts, it will say it doesn't matter.

Look! How humble they are and how helpful they are! They unite as one and serve the people silently. Not only the family, but also serving the people and bricks.

Not only do they unite as one, but we humans should also unite and help each other like them. Looking at them, I feel: share weal and woe!
