passive sentence began with auxiliary verb + the past participle form

[Mohammad Ahmad]

Vocabulary lexical question in grammar :
As we know the passive sentence began with auxiliary verb + the past participle form, but till now I didn’t see any one use the auxiliary verb do or did or the derivatives verb does …..
Let me say that, I find the possibility in that why no ?
e.g. what do u. mean ? what he meant by that ? or: what does he mean by that ? or: what did he mean by his speech ? .. etc.
while I am wanting to say what does he meant , or what does it meant , I find the smell of the passive here .. why no ..let me see your opinion or your suggestion or your deep thought , some times I listen to my self and I find the English language easy and feet able more than other language , but we had to be obliged by our teachers to say what they demand and they always have to say ; your sentence are bizarre and more strange , why we still follow the others as a blind one and have to do what their mind ness need or their mind ness level ? why we didn’t bring the new elements in our thought and have to advocated our theories ? The language are wide and each years had to come a new vocabularies idioms slang or natural , we aren’t in arithmetic to add 1+1 and the result must be two. I am waiting your comments and your geniuses.

I'm not sure I understand everything you have written, but I'll try to explain it.

The only reason not to use "do" for the auxiliary verb in the passive is that it's not the auxiliary verb we use in the passive. There is no reason; it just isn't used, and it doesn't have a passive meaning. In fact, the auxiliary verb "do" has no meaning at all, and so it can't convey any meaning, not even the passive. Also, the auxiliary verb "do" cannot be followed by a past participle, so that's another reason why it can't form the passive.

So the only auxiliaries we use "be" and "get" for the passive, but that is all, if I remember correctly.
