If life is a grass, I would like to offer a little green for spring. How to imitate?

If life is a big tree, I would like to sow a shade for the earth (summer); if life is a flower, I would like to offer a ray of fragrance to the world; if life is a grass, I would like to offer a little green for spring; if life is a bunch of flowers, I would like to dye it brilliant for summer; if life is a big tree, I would like to cheer loudly for the autumn harvest; if life is a fruit.
