haven't finished
现在完成时是以现在的时间为切入点看到问题的,虽然动作发生在过去,但对现在的影响是:我无法加入你们之中去玩.

haven't finished

你把选项写上

must finish或have to finish 或have not finished

haven't finished

haven't finished
我觉得

应该是haven’t finished吧,句子意为我还没有做完作业呢,我恐怕不能加入你(的活动),现在完成时的否定

have not finished
I guess I can't join you.这句为一般现在时那么导致这个结果的原因就应该是现在完成时态

haven't finished
