答案都不对
应该是
WILL BE ON
你是不是把最后那个选项也写错了?
be careful next time!
good luck~

选A。
理由：首先用排除法，排除了D，因为will后一定要跟动词原形（be/do形式）
其次，根据题意：我在看一场比赛，比赛晚上7点开始的，到现在已经持续了半个小时了。“比看赛”是一个发生在过去，并一直持续到现在，并对现在有影响的动作，因此正是现在完成时。而选项里，A是现在完成时，B是过去时，C是过去完成时（动作发生在过去并在过去结束）
综上所述，选A。...

选A。
理由：首先用排除法，排除了D，因为will后一定要跟动词原形（be/do形式）
其次，根据题意：我在看一场比赛，比赛晚上7点开始的，到现在已经持续了半个小时了。“比看赛”是一个发生在过去，并一直持续到现在，并对现在有影响的动作，因此正是现在完成时。而选项里，A是现在完成时，B是过去时，C是过去完成时（动作发生在过去并在过去结束）
综上所述，选A。

收起

CHAD been 过去完成式。

选D
因为句子的意思是，我在看比赛，七点开始的，还有半小时才结束，所以不应该是过去的时态，排除B C，A是完成时也不对，应该是将来时，还有半小时。

A.has been 后面应该有一个on
现在完成式（has been）跟一段时间连用for+一段时间
