用法筆記
Often used with verbs of occurrence, movement, or communication — for example, happen, occur, arrive, speak, start, press, buzz, or ring. The word can move freely within a clause without changing the core meaning: before the main verb (simultaneously checked), after the verb phrase (opened simultaneously), or at the start of the clause (Simultaneously, the audience rose).
