You did a venderful job,just with some little grammar problem.So let me try do some thing for you if you don't mind...
Kevin Garnett is my favourite basketball player.He is very handsome and sexy.He's from the US and plaied basketball for Celtics,Boston
I love him very much because he worked very hard.No matter how difficult,he never gave up.Till the end of his seccess,he got the coveted championship ring.But now he is suffered from injuries.He is no longer able to touch rebouds above.But I still cared about him just like before.Because I am not only appreciate his playing but also his attitude for everything like:serious,persistent and fearless.He taught me how to active during my life.Of course he is very attractive that's only part of all the reasons that I love him.
He is my favorite person.I will love him forever.
