生病短语用英语表示为 "to fall ill" 或 "to become ill"。这两个短语都指的是生病。
"to fall ill" 来源于古英语中的 "feallan"，意思是 "倒下" 或 "倒地"，后来引申为 "生病"。
"to become ill" 则是由 "to become" 和 "ill" 两个词组成，"to become" 意思是 "成为"，"ill" 意思是 "不适" 或 "生病"。
例句:
He fell ill last week and had to stay in bed for a few days. (他上周生病了，不得不卧床几天。)
She became ill with a cold. (她感冒了。)
