My dream was to see some real snow, so during the Christmas holiday, we took our passports and flew 1 the Pacific to Calgary, Canada. We took a bus to a ski resort in the Canadian Rockies. As the bus climbed 2 the mountains, we saw the thick snow on the trees. I was 3 (die) to get out and play with it! At last, we reached the resort and quickly jumped out of the bus. This was our first experience with snow. We were like little children – we made snowballs, and threw them at one another! Then we checked in at the hotel. We could see the ski slope 4 the hotel. We could not wait to go skiing. The next day, we put on our ski suits and gloves, took our skis and went outside onto the snow. 5 (wear) skis for the first time made me feel strange. Suddenly I found 6 (I) 7 (able) to walk! Then we had a skiing lesson with a young couple. Our instructor took us to a gentle slope, and showed us some basic skills. To be honest, that first lesson was not a great success. I kept on 8 (fall) over, and I had to hold on to a rope to keep my balance. However, the next day, I only fell over a few times, and I managed to do a few rapid runs. I felt 9 (please) with myself, and my instructor told me I was doing much better. 10 it was very cold, I spent most of my holiday skiing. I had a wonderful time. It was all over too soon. It was a shame, but we had to leave. I wish my parents would take me back for another wonderful skiing holiday this year. More practice Read this article about the Olympic Games.
