X. Read the email then answer the questions. From: Brett.walker149@gmail.com To: Subject: Re: sports Dear Brett Thanks for your email. You do lots of sports at school in Canada. I’d love to play ice hockey one day. We do lots of sports at our school too. We’ve got a swimming pool at school and our class go swimming every Wednesday. We also play tennis, volleyball and football, but football in Australia is different to soccer. You can touch the ball with your hands! There are lots of after-school sports clubs in Australia too. I go to a surfing club after school on Tuesdays and Thursdays. We go to the beach and learn how to surf. It’s great fun! Can you surf in your country?
