Could you tell me if I can say

I want to present you something
instead of
I want to present you with something.

Is the first sentences correct?

present somebody with something, usually to accuse or criticize; "We confronted him with the evidence"

Is this the meaning you want?
'Present' takes 'to' if 'you' is the recipient; otherwise, 'you' would be the object. The choices:

I want to present an award to you. (= give)
I want to present you to Pope Benedict XVI. (= introduce)
I want to present you with an award. (= give)

As you can imagine, 'I want to present you Pope Benedict XVI' or 'I want to present Pope Benedict XVI you' would be quite strange.

By 'present' I meant "to show" or something like that.

What do you think about my examples?
a)I want to present you the results of my findings.
Should it be?
b)I want to present the results of my findings to you.

I want to present you with the results of my findings.

If 1(a or b) and 2 are correct, what's the difference between 1 and 2?

Ah, I see. #1b in this case means to me 'make a presentation of' or 'show' the findings ('results of the findings' seems redundant, by the way; 'results' = 'findings'), while #2 seems more to suggest a 'gift' or 'submission' of the findings. Not a big difference in this instance, but perhaps significantly different in other cases.

#1a is certainly intelligible, but not, I believe, grammatical.
thank you Mister Micawber,

I have one more question that I hope will clear my doubts.
Could you please tell me when the difference between 'present sb with sth' and 'present sth to sb' is significant? ( in which other cases)

Could you give any examples or maybe some general information on when to use which of the constructions with "present'?

Well, Yogi, my brain and other current resources do not come up with a clear answer for this.

Creating hypothetical sentences in my head produces the feeling that (when 'present sb with sth' and 'present sth to sb' mean 'show' or 'give') the latter suggests the more straightforward action from giver to receiver, where the former suggests a sort of fait accompli or a greater focus on the gift itself.

'This presents us with a problem' is not concerned so much with the source as it is with the resulting situation. 'This presents a problem to us' seems a bit unnatural here, for that reason ('this presents a problem for us', however, works fine-- but is not our concern at the moment).

'She presented us with her homework', contrariwise, sounds a little unexpected because the activity-- the handing over and receiving of the assignment-- is what we are focussed on rather than the result. Here, 'she presented her homework to us' seems more usual to me.

That is all the significance I can extract from these two forms. Perhaps we can get an opinion from another member.
