时态讲解！谢！have you been fighting against your brother again?

这就话是说："你又和你得兄弟打起来了吗？"这句话的意思我明白，可是时态我老是搞不明白。这句话的肯定形式是：you have been fighting against your brother again.这是什么时态？fight为什么要加ing ？为什么要加been,直接写成you have fighted against your brother again.（用现在完成时）不行吗？那么疑问句应该是：have you fighted against your brother again?难道这样写不对吗？我好困惑请赐教！
