If you don't mind,I could provide an explanation in Chinese. smettere:（动词原型）停止，中止。 smetterà 是这个动词的第三人称将来式。 fare il pompiere：做消防队员，从事消防员这个工作。 句子的意思是：可能他将不再从事消防队员这个工作。 PS:Could I put another question here,folks? Is it still correct if it is translated into "Maybe he's going to quit as firefighter."? Is "quit to be" equal to "quit as" in all senses?

Maybe he's going to quit to be a firefighter
