Question

【题目】 ---Excuse me, Mum. When can we have dinner?

---Not until it ___________ in half an hour.

A. is prepared B. will be prepared

C. has been prepared D. was prepared

Answer 1

【答案】A

【解析】

试题分析：句意：-打扰了，妈妈。我们什么时候可以吃饭？-再有半个小时就准备好了。结合语境可知下文为省略句，根据连词until可知后面状语从句，根据语境及时间状语可知下文主句描述的是将来的动作，故条件从句中用一般现在时态表示将来动作，故选A。
