Conjugaison du verbe "to be" après "none" en anglais

Question

Dans les notes, le prof écrivait plusieurs fois "None of them are ....".  En fait, "none" en anglais est une contraction de "not one", si la bonne conjugaison du verbe en anglais serait "None of them is .....".

Accepted Answer

William, 
this debate may be nearly as old as the word ‘none’ itself.  Either singular or plural verb form can be correct English grammar, depending on context, and there is a note in the lesson on this. 
There are examples of both English grammatical forms in the lesson - with the point being that the singular verb form is always used with aucun/aucune in French, regardless of whether the English form could be singular or plural.

Ha! Indeed, something you could argue over long into the night!!

I'm going to stick my head above the parapet and say that in less formal spoken English, where there is an option, I think you'd hear the plural verb form more often than not...
