Which present do I should pay for teacher(girl) as a final gift? She is about 28 years old . She teaches us Physics. And I want to know . Which present most of young teacher like?? Any Suggestion!!

Because she's a teacher you are in "love" with I would buy her nothing.

Yeah... but I want to give present her as a teacher.. not my girl!

I repeat what I said - any present is inappropriate. You have feelings she cannot share because she's your teacher. I'm not sure it's appropriate for her to accept gifts.

Leave her alone.

I want to tell you... I give her present as a teacher not a girl... Not only me but also all of my friends will also give all the teachers...
You r just misunderstanding...

No, I think you're the one that is misunderstanding. Judy is absolutely right, any personal gift from you would be inappropriate in this situation. If all of the other students are really getting gifts, then perhaps the class should get a gift together as a group and you can contribute to it.
