What is the passive voice of this sentence…?
“He will be driving to Russia”: A native speaker will not put this sentence into the passive voice. Your first suggestion (“Russia will be driven to by him”) is technically correct and does employ the passive. But you wouldn’t hear a native speaker say it. In linguistic terms, it lacks “grammatical competence” – it’s theoretically correct, but you’ll never see or hear it. Your second option (“To Russia will be driven by him”) is wrong – there’s no subject in the sentence. “He will be driving us to Russia”: The usual formation of the passive version would be your first option, “We will be driven to Russia by him.” But it’s unusual to see the passive used with the pronoun like that – it’s more likely to be “We will be driven to Russia by Sergei.” Your second option (“To Russia we will be driven by him”) is another example of a lack of “grammatical competence” – technically the syntax is correct, but you’ll never hear it. It’s just not the word order we use in English.
