Our coach forbids (us) 'drinking'/'to drink'?

Question

In my grammar book "Grammatica Inglese Facile (Simple English Grammar)" I read that the following sentences are both correct:>- Our coach _forbids drinking_.>- Our coach _forbids us to drink_.But the book adds that the latter cannot rewritten in this way:>- Our coach _forbids us drinking_.However the book doesn't explain its last statement, thus I'm asking if someone can explain whether what the book states true is. If so, why?

Answer 1

You can say Our coach forbids drinking instead of Our coach forbids us drinking. Our coach forbids us to drink is the more acceptable use, as an infinitive. Our coach forbids that we drink also sounds clunky (if you understand what I mean by clunky). It is understood that 'Our coach forbids drinking' would apply to his team members. I couldn't find a specific name for the use of 'us' with a gerund, drinking.
