Intransitive verbs can't be put in the passive voice.

As Chris says, there is no passive voice form of this sentence.

Why is crying being done by you? Just joking - the others are right - it can't really be put into passive voice.

Mingalabar, There is no passive for this, Aung. Passive. Life can only be used with certain verbs, actually transitive verbs that means those verbs have an object. Cry is not a transitive verb, therefore no object. If you want to know more on this, you are welcome to afl or have a free class with me.
