IV. Read Leo's report about his favourite sport. Choose the correct answer A, B or C "Water polo is a new sport at our school, but we have a good team now. We practise after school on Thursday at the Northside Pool and we're doing well in the National Schools Competition. There are seven players in a water polo team. The game is a bit like football because each team tries to score a goal with a ball. But in water polo you don't use your feet - you catch and throw the ball with one hand. And you never stop swimming. A game lasts 32 minutes, and in that time you swim up and down a 30-metre pool lots of times. If you aren't fit, water polo isn't the sport for you! For me, it's great, because I love being in the water and I can swim fast. I also enjoy being part of a team. We have some excellent players and we're all good friends. So it's fun, and it's also a fantastic way to get fit." Leo Johnson 1. People play water polo __________. A. in a stadium B. in a swimming pool C. at the beach 2. His team plays __________.
