- 1危及生命的、可能致命的
A life-threatening illness, injury, or situation is one that could cause a person to die. Doctors use it with care: a bad cold is not life-threatening; a heart attack may be. News reports use it for accidents, storms, and disease. It is serious, ordinary-to-formal English, not a joke. Though actually “could cause death” is the test, not “feels very scary.” Many painful things are not life-threatening, and a quiet problem — internal bleeding, a hidden allergy — can be. Before a noun, the is the normal spelling: a life-threatening injury.
「life-threatening」指可能讓人死亡的疾病、傷害或狀況。判斷的標準是可能致死，不是看起來很嚇人，所以很多痛的情況並不算，而一些不明顯的問題，例如內出血或隱藏的過敏，卻可能是。醫生會謹慎使用這個字：一般的重感冒不算，心臟病發作則可能算。新聞也常用它來形容意外、暴風雨和疾病。它的語氣嚴肅，放在名詞前通常加連字號，例如「a life-threatening injury」危及生命的傷害。
From the word’s history
