A few minutes ago chuyển thành gì trong thể bị động zậy. Tự dưng quên mất tiêu :))

- A few minutes ago khi chuyển sang bị động thì vẫn giữ nguyên.

Ex: I bought a present a few minutes ago.

-> A present was bought a few minutes go.

- A few minutes khi chuyển sang câu tường thuật thì là " a few minutes before" 

Ex: " I came a few minutes ago." She said

-> She said that she had come a few minutes before.
