短语
paint the Forth Bridge
- used to indicate that a task is never-ending用以表示没完没了的事情永远完不成任务：
it's all over for another year except that we must immediately set about seeking next year's sponsor - it's a bit like painting the Forth Bridge.
又一年过去了, 只是我们必须马上开始找来年的赞助商——这有点儿像一件永远完不成的任务。
ORIGIN: with reference to the fact that the railway bridge is so long that once its painters had reached one end, they would have to begin again at the other.
