English is kept on being spoken by her.
Let me break down why:
* Subject: The original subject is "she," but in the passive voice, it becomes the agent (who performs the action). This is often placed in a "by" phrase at the end.
* Verb: The verb "keeps on speaking" becomes "is kept on being spoken." This uses the auxiliary verb "is" and the past participle "spoken."
* Object: The original object "English" becomes the subject of the passive sentence.
While grammatically correct, this passive sentence sounds quite awkward and unnatural in English. It's much more common to use the active voice, which is more direct and concise.
