英文問題:In a flash是什麼詞?

意思是「一瞬間」或一段很小的時間，好似閃光燈閃一閃送這麼快，不是"突然間"
e.g
I will be back in a flash.

It is a phrase.

To be exact, it should be called a prepositional phase ( because there is a preposition in front of the phrase e.g. in the morning, over the rainbow).

It is a ph.It means for a short period of time.NOT SUDDNELY

In a flash 解作 非常快

這是口頭慣用語，屬副詞
