A great French writer said that we should help everyone as much as possible because we often need help ourselves. The small even can help the great. To this effect, he tells a simple story. 

An ant was drinking at a small river and fell in. She tried hard to reach the side, but made no progress at all. The poor ant, almost tired out, was still bravely doing her best when a bird saw her. Moved with pity, the bird threw her a blade (叶片) of grass, which supported her like a boat, and thus she reached the bank again. While she was resting and drying herself in the grass she heard a man coming near. He was walking along barefooted and carrying a gun in his hand. As he saw the bird he wished to kill her, and he would certainly have done so, but the ant bit him in the foot just before he raised his gun to fire. He stopped to see what had bit him, and the bird immediately flew away. It was an animal much weaker and smaller than herself that had saved her life.
