文法句型

convulse with + [laughter/anger/sobs/grief]

用法筆記

Almost always used with 'with' followed by an emotion noun. The subject can be a person ('he convulsed with laughter'), a body part ('her face convulsed with grief'), or a group ('the room convulsed with laughter'). Never used transitively in this sense — you cannot say 'the joke convulsed him' (you must say 'he convulsed with laughter at the joke').

常見錯誤

❌The joke convulsed everyone.
✅Everyone convulsed with laughter at the joke.
💡This sense is always intransitive and requires 'with + emotion'.
