If you win / won 1 million dollars, please give me some.

Which bold word should I use? Thanks.

I'd say: If I won a million dollars please give it to me.

This would imply that somebody said you had won the million dollars, and now you want to get paid.

Using win would imply that it might happen in the future.

If I win a million dollars, I am going to live in France.

I am going somewhere there is no snow.

I'd say: If I won a million dollars please give it to me.

But if you won a million dollars would you give some to me?
( for a train ticket to come visit you in France f.i.?)

But if you won a million dollars would you give some to me?

But of course.

(for a train ticket to come visit you in France f.i.?)

How did you know I was thinking of moving to France? I work with a fellow who left Paris to work and live in Sunnyvale. I spent two years working in and commuting to Sunnyvale, and I would rather live in Philadelphia or Emden.

Ah, so this was just an example. Well, Paris is France but France isn't Paris.

Well, Paris is France but France isn't Paris.

I would probably live out in the provinces. Paris is a nice place to visit but not necessarily where I would want to live. (Oh, all right if somebody gave me an apartment in Paris, Id use it as a ]i]pied-à-terre[/i].

... was in 1954. I've visited La Belle France many times since, but have absolutely no desire to re-visit that lovely city inhabited by rather unlovely people. The oinhabitants of the rest of France are, by and large, excellent and ffriendly people.
(One might well say all that about London, too! - I was born on London's outskirts, but have emigrated 'up North' and try to avoid visits to the captal as far as possible!)

One could say the same is true of the
very busy residents of New York City.

... and probably of all Capital cities (except Oslo, of course!)

Somebody once ran a test of willingness of people to help out someone in need. They ran the test in New York City and Memphis. They had someone stopping pedestrians and asking for a small sum of money for a good purpose. The good citizens of Memphis were much more willing to help out than were the citizens of NYC. Then they figured that maybe they weren't playing on a level playing field since the NYCers would have many more demands upon their generosity. So they seeded the Memphis crowd with beggars that the Memphis folks would have to pass by before meeting the target. The NYC folks did far better than the Memphis folk in this adjusted test.

I'll bite, why not Oslo?

I notice that the original question has only been answered partially.

saying:
if you win 1 million dollars, please give me some
This definitely and correctly refers to a future possibility.

saying:
if you won 1 million dollars, please give me some
the phrase refers to a past fact, i.e. the beggar has been told that you won.
The other possibility is the past subjunctive mood. In that case the first part of the sentence would refer to a hypothetical (irreal) possibility (like "if I were a rich man") - and your original second part would not fit it, as Branshea correctly remarked.

You win, wsieber. You won my heart with this one.
But if, for example, I won 1 million dollars I will not give you none.

I guess you have to live there to really understand. The capital of Norway is just one fair-sized provincial town and has no real sense of urgency. It's a nice place, if a bit boring! Mind you, it may have changed since I was there, which was quite a while ago!

Gotch'a thanks.
