The children were above themselves having heard about the suprise. There's no sense to wait for help from above, I should solve the problem by myself.

The manager was impressed because Le Yunyi went above and beyond his expectations and performed excellent work that she did not need to do! "There is no need to get above yourself" said Lee.

1. the sun is ABOVE us. the rainbow is OVER us. the hat is ON my head. my idea: "above" is to show a point higher without contact/touch, "over" is to show a track or a area higher without contact, and "on" is to show something high but has directly touch. 2. the road is BEYOND the hill. i think "beyond" means far out a certain range.
