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
