问答题

Joy in living comes from having fine emotions, trusting them, giving them the freedom of a bird in the open air. Joy in living can never be assumed as a pose, or put on from the outside as a mask. People who have this joy do not need to talk about it; they radiate it. they just live out their joy and let it splash its sunlight and glow into other lives as naturally as birds sing.
To speak truly, few adult persons can see nature. Most persons do not see the sun, at least they have a very superficial seeing. The sun illuminates only the eye of the man, but shines into the eye and the heart of the child. The lover of nature is he whose inward and outward senses are still truly adjusted to each other; who has retained the spirit of infancy even into the era of manhood.
