A Skiing Holiday in the Italian Alps
Three years ago I went with some friends on a skiing holiday in the Italian Alps. We flew to Milan airport from London and then took a coach to Trivera. There was a lot of snow on the mountains and the sun shone every day. The snow conditions were great. We skied a lot and on some days I took lessons in ski school to learn new techniques. In the evenings we went to the local discotheque. We danced and met a lot of people. At the beginning of the holiday I was an intermediate skier, but now, after those ten days, I'm an advanced skier.

How long did the young man stay in the Alps?
