From: Rustam To: Sam Subject: Hello from Almaty! Hi Sam Thanks for your email about the London 0lympics. It sounded amazingl You were lucky to get tickets for the 100 metres finall
i am lucky too because I went to the Asian Winter Games in 2011. Did I tell you about it? It happened in the winter, so the sports were different from the summer games, For example, have you heard of bandy? It's a bit like ice hockey, but there are players in each team and they play with a small red ball A lot of the events were in Chimbulak, about 25 kilometres from Almaty. Other events happened in Astana. My dad and l went to see some of the skiing events. When we arrived, we couldn't believe how many people were there. heard on the news that 2,000 journalists and 10,000 visitors came from other countries to watch the games incredible! Kazakhstan did really well in the skiing events l saw We won a gold medal in the women's and men's ski orienteering, and two gold medals in the freestyle skiing. Then won two more gold medals in the cross-country skiing, so six in total. In fact, we won 70 medals all together and we came top of the medals table: 32 gold medals, 21 silver and 17 bronze. Japan came second and South Korea was third What happened to stadiums in London when the 0lympic Games finished? When the Asian Games finished here, the Kazakhstani people could use the stadiums and the ski slopes. I'm really excited because this year, my family and are having a holiday at Chimbulak ski resort, and I'm going to have skiing lessons. Perhaps one day, I'll compete in the Asian Games Best wishes Rustam
