Skiing

by Vanessa Luo 

Skiing is my favourite sport，even though I have only skied for four days in my whole life!Last year my father promised to take me on a holiday if I did well in my exams.When I got straight A's, Dad said, "How about a weekend at the Botanical Gardens?"

However, my mum said, “No，you promised a special holiday. Ithink you ought to keep your word."And，despite the expense，he did.

My dream was to see some real snow，so in the Christmas vacation we flew to Seoul，South Korea, and then took a shuttle bus which runs back and forth between Seoul and Muju Resort. As the bus climbed through the mountains，we saw the snow onthe trees. I was dying to get out and play with it! At last, we reached the resort and quickly scrambled out of the bus.

No one in my family had ever touched snow before. We were all like little children-we picked it up，made snowballs，and threw them at each other!

Then we checked in at the hotel. Our room overlooked one of the ski slopes. The slope was floodlit,so we watched people skiing until 10 p.m. We could not wait to try it ourselves.

The next day we had our first skiing lesson. We rented our ski suits, boots and skis, and went outside onto the snow. Wearing skis for the first time makes you feel very strange. Suddenly you find you cannot even walk.

Our instructor took us onto a gentle slope，and showed us some basic skills. In order to go up a hill，you have to stand sideways, and go up step by step. You must point the tips of your skis together sothat youcan stop.

However，the tips must not cross，or you willfall. You should not ski alone in case you fall and get injured. To be honest, that first lesson was not a great success，and I kept on falling down!  However, the next day, I definitely improved, Ionly fell over a few times，and I managed to do a few longer runs. I felt pleased with myself, and the instructor congratulated me,so I felt great.Althoughit was very cold, I spent most of that holiday skiing. It was the most wonderful time of my life. Nevertheless，it was all over too soon. Now I have decided to work part-timethis summer, so I can earn enough money for another super skiing holiday
