    Re: grammar

    You don't have to change the modal here, it can stay as it is.
    The lesson can be explained is fine.

    Yes. In fact, it's stronger than "You don't have to". You shouldn't - otherwise you're doing something more than just changing the sentence from active to passive.

    Re: grammar

    Either is correct depending on context and what you want to express.
    "The lesson can be explained". (Someone is able to explain the lesson with no qualification or condition)
    "The lesson could be explained." (Suggests that there might be some qualification or condition that has either been stated previously or will follow.)

    Re: grammar

    bill, that's true that either COULD be correct, but the original sentence in the active voice used "can" and the transformed sentence should use the same form or you change the meaning of the sentence.
    I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.

    Re: grammar

    Hi Barb_D,

    I'm not sure I understand your comment but yes, each of my examples has a different meaning. "Can" indicates an ability and "could" suggests a possibility "if" something else occurs or some condition exists. I'm in PA too. Where are you?

    Re: grammar

    The clue is in the original poster's first line. He wants to know how to make a passive voice sentence from an active voice sentence.
    The passive voice equivalent of: "The teacher can explain the lesson" is
    "The lesson can be explained by the teacher", not
    "The lesson could be explained by the teacher."
    That's all it is.
