今天，我知道了什么是团结力量大，植树节老师让我们分组三人植一棵树。
Today, I know what is unity and strength. The tree planting day teacher asked us to plant a tree in three groups.
开始植树了可是三人都想自己植，不想让其他人参与，就这样三人发生了争吵。
They started to plant trees, but they all wanted to plant by themselves, and they didn't want other people to participate. So they had a quarrel.
老师看到了就过来了给我们讲了一个团结的故事，听完之后三个人想变了个人似的互相帮助。
When the teacher saw it, he came and told us a story of unity. After listening, the three people wanted to help each other as if they were individuals.
就这样三人从此团结友爱互帮互助。
In this way, the three people will unite, love and help each other.
