Hi, my name is Darwin Watterson, I'm ten years old and I live in Elmore. I go to school from Monday to Friday but when I'm not at school, I practice sports. My favorite sports are extreme sports, especially water sports. I practice white-water rafting, kayaking and canyoning.

I always go kayaking on Monday and on Wednesday. When I finish school and after I finish my homework, I take my kayak and I go to the beach with my friend Tobias. On Tuesday and on Thursday, I go white-water rafting. You need a group to do white-water rafting, it is difficult but it is really exciting. I go canyoning on Friday afternoon. Canyoning is my favorite sport: you have to go down a river canyon using your hands, legs and some ropes. You need some special equipment to practice canyoning: you need a helmet to protect your head, a wetsuit not to feel cold, ropes and harness to go down the canyon. Finally, I take a rest on the weekend to play some videogames with my brother, Gumball. He doesn't like practicing sports.

When does he play video games with his brother?

What is his favorite sport?

He always gets up late and _______.

_______ do you go to school? Every morning.
