| 释义 | fast (once / 46 pages) 1adjadv 2adjadv 3adj 4adj 5adj 6vn When you see fast, you might think of Olympic runner Usain "Lightning" Bolt or a Porsche 911 Turbo.

Fast is another of those deceptively simple words that have a number of other meanings beyond their most common usages. If something "sticks fast" it means it cannot be removed — like a leech or a stain. "To stand fast" means not to give up your point of view or to remain loyal. Then there's also the slang meaning of living beyond the constraints of normal behavior — as in "the fast life," "the fast track," or "the fast lane."
