Let‘s see if the baseball game has started yet.
Started?It must be clear who ( ) by now.
A:is winning B:wins C:has won D:would win
这题选A:is winning
原句还原是：It must be clear to find out who is winning at the moment（by now）
by now 可用于多种时态,要根据语境具体分析哦.

到这时,罗马帝国已日益衰败.

如对回答满意,
再问： 答案说选D！是答案错了吗
再答： 嗯，可以保证答案是A，这题之前做过。 解析如下： 句意：让我们看看篮球比赛是否已经开始了？开始了？现在一定能看出谁将赢了。B一般现在时，表经常性动作或状态，明显不对；C现在完成时，表动作已经完成，也明显错；D过去将来时，表过去某时间之后要发生的事情，也不对，故选A，现在进行时表将来。
