But hot tempers on a hot rock beats being on the outside trying to get in. This exclusive resort, isn’t accepting new guests.
Come evening, a cool mist hangs over the lake, as the last of the egg-laying caddis flies get picked off by ducks and bears.
Brown bears are crepuscular 1, preferring to venture out at dawn or dusk. They have a fantastic sense of smell, and can track the scent 2 of the carcass for over three kilometers. But they are not alone in that respect. Two predators 3 are after the same prize, but there is no way a fifty-kilogram wolf will challenge a 500-kilogram bear. Getting in first, the weaker wolf steals what it can, a large leg bone, but stopping to watch its back is a mistake.
adj.晨曦的；黄昏的；昏暗的
- Bats are crepuscular creatures.蝙蝠是在黎明或黄昏时分活动的动物。
- It has nothing to do with walk,this is called a crepuscular walk.这和散步没有任何关系，这叫黄昏漫步。
n.气味，香味，香水，线索，嗅觉；v.嗅，发觉
- The air was filled with the scent of lilac.空气中弥漫着丁香花的芬芳。
- The flowers give off a heady scent at night.这些花晚上散发出醉人的芳香。
