«I come from England but now I live permanently in Quebec, Canada.When my parents __________________(BRING) me to Canada, I was fifteen.»
I come from England but now I live permanently in Quйbec, Canada. When my parents __________________(BRING) me to Canada, I was fifteen. It was the winter and I __________________(IMPRESS) by the amount of snow there. I asked my new friends what they usually __________________(DO) for entertainment in such a cold climate. Their answer was simple, “In winter __________________(CHILD) and adults go skiing and skating.”Before arriving in Canada I had never tried skating and my Canadian ice experience was really painful. To start with, it took __________________(I) half an hour to pu on the skates. I _________________(NOT/KNOW) how to move so my new friends showed me some basic techniques. However, when I was left alone on the ice, I __________________(FALL) over immediately. When I opened my eyes, my new friends were standing around. They weren’t laughing, they looked worried. “Are you OK?” they asked. “Fine,” I said, “I wish I __________________(CAN) skate as easily as you do.” “You definitely will,” they smiled. And they were right. By the end of my __________________(ONE) winter in Canada, I felt confident on the ice. More than that, I found out that skating was a really exciting activity!
