"it is about ski" - the commonapp 150words short answer

it is about ski, but I think the ending should be improved and some unneceessary part should be deleted. Maybe the beginning should be revised too. anyway, just please give me some comments, thanks a lot!

A perfect parabola swept over the snow-white world and that meteor was me.
I started skiing when I was in primary school. I can still remember the first time I wore the ski boot--the tight feeling around my shins increased the tension deep inside my heart. And the nervousness get even worse as I standing on the top of the small hill since I am a little acrophobic. I stood still Looking down at the height under my feet until my classmate playfully pushed me down. Wind whipped through my coat and tore at my face. I wanted to stop, but the board attached to my feet just go down faster and faster. I arrived at the foot of the hill, surprisingly, without a tumble. It's amazing! Skiing seems to be intimidating at first, but the excitement after landing at the foot keeps me do it again and again.

"A perfect parabola swept over the snow-white world and that meteor was me."
I would add a comma between world & and....^here

"And the nervousness get even worse as I standing on the top"
1. It is generally a bad idea to start a sentence with "and".
2. "get" should be "got"
3. should be "...as I was standing at the top"

still L ooking
should be lower case

foot keeps me do it again and again
This isn't written as clear as it could be, but if you keep it this way "do" should be "doing"

I'd have a teacher look over this for you, you can do better with grammar.

thanks so much for your advices~!

Use a comma for a compound sentence:
A perfect parabola swept over the snow-white world, and that meteor was me.

I started skiing when I was in primary school. --I don't think this sentence is necessary or helpful.

I can still remember ---this is a cliche... overused.

This is great description! ---> first time I wore the ski boot--the tight feeling around my shins increased the tension deep inside my heart.

Don't capitalize that L unnecessarily.----> Looking down ...

This is a nice description of skiing, but it is possible to somehow infer some meaning or significance? Something it taught you about your own personality?
