a grammar question

<p>someone told me that if a sentence is in passive voice, the preposition "on" can only be followed by "the", but not words like "his". SO</p>

<p>Tom was hit on the head with a baton. CORRECT
Tom was hit on his head with a baton. INCORRECT</p>

<p>is there such a rule?</p>

<p>Is this tested on the SAT?</p>

<p>i can't remember exactly, he said it was on Jan 2009 test; the correct answer choice was
"was hit on the..." and the other was "was hit on his ... "; so he told me sth like i said before</p>
