I am a British English Teacher, so I am not familiar with the North American use of "gotten" in the Passive Perfect Tenses. In these tenses, does the word "been" always get replaced by "gotten" in American English or is it sometimes a choice between "gotten" & "got"?
Here are some example sentences, can you give me the correct passive form in American English please?
The flying car had been invented by Oleg before he died.
The flying car had got \ gotten invented by Oleg before he died.
The report has not been published by the government.
The report has not got \ gotten published by the government.
