They're studying old, dead, stale coffee!

它们在研究陈旧、死的咖啡！

Stale coffee in some greasy spoon.

路边小店里的劣质咖啡。

Outside of some of the doors were trestles with banked-up oranges and apples, spotted pears and dusty raspberries; and the air reeked with the smell of fruit and stale coffee, beer and sarsaparilla and fried potatoes.

几扇门外的架子上放着堆成一团的橘子和苹果、有斑点的梨和落满灰尘的覆盆子。空气中弥漫着水果、陈旧的咖啡、啤酒、菝葜和炸土豆的气味。
