[译] 患病的工程师已经康复。
[误] The ill engineer has recovered.

[正] The sick engineer has recovered.
[注] ill 和 sick 都是形容词，都可作表语，如：He is ill with bad cold. 他患重感冒。/I began to feel sick as soon as the ship started to move. 刚一开始我开始恶心。做完语时 ill 可作"邪恶的"、"坏的"解，无"生病的"之意；而 sick 可作"生病的"解，如：I visited a sick friend in hospital yesterday. 昨天我到医院去看望过一位患病的朋友。
