1个回答

prepare作此意讲时是及物动词 应该直接接物,而不需要其他介词,

有个用法是prepare sth for sb 意思是：为某人准备某物

下面是详

prepare vt.

1.准备;使...准备好[(+for)][O2]

They prepared themselves for the worst.

他们作了最坏的打算.

2.筹备,筹划[(+for)]

3.做(饭菜);制作;调制[O1]

When we arrived home,mother had already prepared dinner for us.

当我们到家时,母亲已为我们准备好了晚餐.

4.起草;编纂

不及物动词 vi.

1.准备,预备[(+for)][+to-v]

I was preparing for bed when I heard a knock at the door.

我正准备睡觉时听到有人敲门.

希望能够帮到你!
