為什麼你使用not before而不是after ?

Rachel 說不not before此之前的原因是為了補充她之前的評論, Right after you left, they wheeled her off to the delivery 。通過使用not before ,您表明這是她去產房之前發生的事情。 not before可以表示打算在開始之前完成某件事!例: After breakfast, you can go outside, but not before the dishes are washed. (吃完早飯,洗完碗就可以出去了。) 例子: She left the room crying, but not before she cursed the teacher out. (她罵完老師後哭著離開了房間。)
