英语好的同学来帮~：求“Tom eat an Apple”的被动语态，和must，mustn't，needn't和had to的中文意思及用

被动语态要：一般现在时，一般将来时，现在进行时，一般过去时，现在完成时，过去完成时，过去进行时，must，can的语态（就是把Tom eat an Apple转化成那个句子）。
请顺便把定义写上去：如当一般现在时时：Tom后加BEING？（指什么什么词（态）如加过去分词）

首先，“Tom eat an Apple”是错误的。改为Tom eats an Apple（不推荐这个。一般现在时一般用来陈述说明性的事情）或者Tom ate an Apple(推荐改为这个，表示已经发生的事，用过去式)。
被动语态：
一般现在时：An apple is eaten by Tom.
一般将来时 An apple will be eaten by Tom。
现在进行时 An apple is being eaten by Tom.
一般过去时 An apple was eaten by Tom.
现在完成时 An apple has been eaten by Tom.
过去完成时 An apple had been eaten by Tom.
过去进行时 An apple was being eaten by Tom.
must句型 An apple must be eaten by Tom.
can 句型 An apple can be eaten by Tom.
