三者均可表示“随身带着”,有时可互换。如:
I have no money about [on, with] me. 我身上没带钱。
三者的细微区别是:
(1) about 一般指随身带的小物品:
Have you a ballpoint pen about you? 你身上带圆珠笔了吗?
(2) with 多指带较大的东西(也可指较小的东西):
He took an umbrella with him. 他随身带了把伞。
(3) on 表示带在身上(如在口袋里):
Have you any money on you? 你身上带有钱吗?
此例若用 with 或 about,则不一定放在身上,也可能放在皮包里等。
