in its true nature

Pluto is not included in either category, because its great distance from Earth and its small size make this planet's true nature a mystery.

冥王星不属于这两类，因为它离地球太远，体积又小，使得它的真正性质成为一个谜。

The value of life-worrying works lies in its transcendency of time and space, of ancient and modern times, of life and nature, thus pursuing "liberal personality" with true significance.

忧生之作所表现出的悲剧精神，其价值就在于它超越时空、超越古今、超越生命、超越自然，从而追求真正意义上的“自由人格”。

Its size will have to be reduced in the next few years -agassiz's admonishment to "Study Nature not Books" posted near the entrance to the library will finally come true.

在未来的几年中，它的规模将不得不有所缩小。贴在图书馆入口处的Agassiz的警语：“钻研自然而非书籍”最终将变为现实。
