If someone is in a coma, they have been unconscious for a long time, usually after a serious injury or illness. They do not wake when you speak or touch them, the way a sleeping person would.

If someone is in a coma如果有人陷入昏迷，they have been unconscious for a long time他們已經失去意識很長一段時間，usually after a serious injury or illness通常是因為嚴重的受傷或疾病。They do not wake when you speak or touch them你跟他們說話或碰他們，他們不會醒來，the way a sleeping person would不像睡著的人那樣。

Doctors watch them in hospital; some people come out of a coma, and some do not. We say in a coma and come out of a coma.

Doctors watch them in hospital醫生會在醫院裡觀察他們；some people come out of a coma, and some do not有些人會醒過來，有些人不會。We say in a coma and come out of a coma我們會說in a coma（處於昏迷中）和come out of a coma（脫離昏迷）。

It is a careful medical word. People sometimes joke that they were “in a coma” on the sofa, meaning only very tired — that is not the real meaning.

It is a careful medical word這是一個嚴謹的醫學用字。People sometimes joke that they were "in a coma" on the sofa有些人開玩笑說自己「in a coma」躺在沙發上，meaning only very tired意思只是說非常累——that is not the real meaning那不是真正的意思。

Though actually, a vegetative state is not the same thing either: the body may still show sleep-and-wake cycles. A coma is deeper and quieter than that.

Though actually不過其實，a vegetative state is not the same thing either植物人狀態也不是同一回事：the body may still show sleep-and-wake cycles身體可能還會出現睡眠與清醒的週期。A coma is deeper and quieter than that昏迷比那更深沉、更靜止。
