I'm a flash animator studying classic animation, theoretically I find some trouble to understand the difference between terms (shot on two's, or one's), but practically I can't differentiate between them at all, say that I'm looking at frames drawn on animation papers, how should I say that this is shot on two's or on one's, and also when I want to draw my frames, how should I distinguish between the two types of animation's rate, is it that I can't do this comparison without the help of a camera, or is it possible just by checking the drawings, or what is it?

Thanks in advance, :)

Usually when they refer to the term Shot on one's or two's they're referring to the key frames. Shot on four's for example would be a key frame every four frames.
How you determine @ which animation rate is depending on what the action is calling for.
As I'm sure you know you always need your key poses..once that is settled than your going to need your primary breakdowns. Primary breakdowns define Overlap, drag, or weight. Once you have those you need secondary breakdowns to help you get from your key poses to your primary breakdowns..these will help you accentuate your drag or overlap etc.. now there's no set number or law (that I'm aware of) that state how many breakdowns you can have...if you need to convey certain information in a short amount of time..then maybe you'd be better animating on two's to get your poses clear and across..maybe you need to convey info in a longer period of time maybe 4's or 8's would be a number for holds or keep alives....

So to answer your question, what rate you animate on is up to you as long as you poses are clear..you may want to check out Jason Ryan or Kieth Lango very affordable tutorials..
I also recommend the book if you don't have it already..The Animators survival Kit..

I always thought the terms 'ones' and 'twos' etc. would tell how long a frame is hold during animation. Lets say whe have 30 fps in an movie. When it is shot on twos, every image is hold for two frames, so you'd have essentially only 15 different images per second. Correct me if I am wrong.

That's correct 15 different poses. One new pose every 2 frames.

My teachers would say sometimes.."This part of the animation seems kind of wrong, when you get to this section trying animating on two's or maybe one's..." That's how they would use the term...

Standard NTSC video would be 30 fps, and if "shot on twos" there would be 15 fps, with each frame repeated twice.
