萬不能已,漢語成語,意思是表示無可奈何,不能不這樣。可以翻譯為have no other choice but,out of absolute necessity。與英文慣用語as a last resort意思相近,表示as a final option, usually when preferable ones have failed。
例句:
這是一個萬不能已的方法。
This is the last resort.
萬不能已時,大夫將進行手術。
As a last resort, the doctor will perform surgery.
不是萬不能已,大家不會出此下策。
If it hadnt been out of absolute necessity, we would not have taken such an unwise decision.
