急求英语演讲稿一篇!关于运动话题的!

i love swimming
i am not that kind of sport person.i have many interests,but not many for sports.i only enjoy watching sports.
but it is a differnet story for swimming.i have been growingly interested in it recently.
what swim brings to me is the feeling of freedom.on the earth,there are animals flying,swimming,and walking.while the other two groupd enjoy three dimension world,the third group can only move at a two dimention surface.unfortunately,human is among the last group.it is really hard for human to fly; fortunately,we can still swim.
within water,the world is expanded from 2 dimension to 3.that is the beauty.
also,swim is not as tough as running.both running and swimming are healthy sports.running,to me,is a kind of suffer; while swimming is really a pleasure.at least,that is my personal feeling.
so,i will keep my current plan,swim three days a week,at least half an hour each time.
