please help me make a choice
--Let's see if the baseball game has started? --Started?It must be clear who ____________by now. A. is winning B. wins C. has win D. will win
选c 不过答案应改为 has won。此题的关键词是by now。 by后面跟过去时间，句子用过去完成时。例如：They had finished the work by the end of last week. by后面跟现在时间，句子用现在完成时。例如：They have finished the work by now。 by后面跟将来时间，句子用将来完成时。例如：They willhave finished the work by next Friday.
妈个B，加上我，就只有三个人知道要选A，大家10年英语怎么学的？ 顺便说一下，be+动词进行时在口语里等于will+动词原型。
是高考题 我上周做的。 C 还没有比完，但是结果已经一目了然。
D. will win 现在都能知道谁将会赢了.
c 这是以前的一道高考题吧
C 谁要胜已经能知道了
A，知道谁快要赢了。
c has won
Ｃ 让我们看看是否比赛开始了 已经开始了 现在 一定是谁已经赢得比赛也清楚了 所以应该是完成时
