Question

【题目】—Mother's Day is coming, what will you do for your mom, Peter?

—I have booked some flowers online and they will arrive two days.

A. inB. forC. before

Answer 1

【答案】A

【解析】

句意：——母亲节就要到来了，彼得，你将要为你妈妈做什么？——我已经在网上预订了一些花，它们将在两天后到达。in two days表示将在两天后，for two days长达两天，before two days在两天之前。根据will arrive可知此处用一般将来时，故用in+时间短语，故选A。
