The very daylight seemed crepuscular; immeasurable clouds, passing slowly overhead, darkened the whole country at broad noon. The wind blew constantly with the sound of a great cathedral organ at a distance, but playing profane, despairing dirges; at other times the noise came close to the door, like the howling of wild beasts.英文原著 · 《AN ICELAND FISHERMAN》
"Both the sharp-tailed and the seaside finches are crepuscular," says Dr. Abbott, in "The Birds About Us." They run up and down the reeds and on the water's edge long after most birds have gone to sleep.英文原著 · 《Bird Neighbors》
It was rather laughable to hear a cadet, who was expounding the theory of twilight, say, pointing to his figure on the blackboard: "If a spectator should cross this limit of the crepuscular zone he would enter into final darkness."英文原著 · 《Henry Ossian Flipper》
Now "final darkness," as we usually understand it, refers to something having no resemblance whatever to the characteristics of the crepuscular zone.英文原著 · 《Henry Ossian Flipper》
"Of all colors, white is the prevailing one; and of white flowers a considerably larger proportion smell sweetly than of any other color, namely, 14.6 per cent; of red only 8.2 per cent are odoriferous. The fact of a large proportion of white flowers smelling sweetly may depend in part on those which are fertilized by moths requiring the double aid of conspicuousness in the dusk and of odor. So great is the economy of Nature, that most flowers which are fertilized by crepuscular or nocturnal insects emit their odor chiefly or exclusively in the evening." - Charles Darwin.英文原著 · 《WILD FLOWERS》
