题目内容
【题目】-Who will be the winner of the speech contest?
-No one can know the result until it ____________tomorrow morning.
A. will announce B. will be announced
C. is announced D. announces
【答案】C
【解析】
试题分析:句意:-谁将是这次演讲比赛的冠军?-直到明天早上宣布了结果才会知道。it (result)是announce这一动作的对象,该用被动语态。虽然由时间状语tomorrow morning,但在时间状语从句中通常用一般现在时代替一般将来时。所以选C。
