A few days ago, our class-外二B went roller-skating in Taipei Arena.  This is my first

time to roller on the knife, I felt interesing and thrilling.    At the begining, I almost fell

down and I very scared, but skated many times, I wouldn't frightened anymore. 

Afterwards, I felt roller-skating is interesting, and I was addict to playing it.  Although

many classmates skated better than me, but I still skated practiced again and again. 

Because I believe, I will skate smooth and be successful.  Maybe next time when I

was free, I would go roller-skating with my classmates.Also, Perhaps, roller-skaing

will become one of my favorite sports.
