The play【 may be begun or may have begun 】already?哪个对?

The play【 may be begun or may have begun 】already?哪个对? The play may have begun already.对不?我认为应该把begun放在already前面吧? It may have begun already It may have begun already.跟It may have already begun.是一样的吗 it may have begun already.这里为什么不用has it may have begun already.这里为什么不用has而用have The day must be breaking,_the birds have begun singing. 还有些 How long have you come here Hurry up!The play has begun the seed had already taken root.it had begun to______ we have only just begun May be or May not翻译中文 the show may begin at any moment.it ()already.为什么要写may have
